Drilling
–
Drilling is a cutting process that uses a drill bit to cut a hole of circular cross-section in solid materials. The drill bit is usually a rotary cutting tool, often multipoint, the bit is pressed against the workpiece and rotated at rates from hundreds to thousands of revolutions per minute. This forces the cutting edge against the workpiece, cutting off chips from the hole as it is drilled, in rock drilling, the hole is usually not made through a circular cutting motion, though the bit is usually rotated. Instead, the hole is made by hammering a drill bit into the hole with quickly repeated short movements. The hammering action can be performed from outside of the hole or within the hole, drills used for horizontal drilling are called drifter drills. In rare cases, specially-shaped bits are used to cut holes of non-circular cross-section, drilled holes are characterized by their sharp edge on the entrance side and the presence of burrs on the exit side. Also, the inside of the hole usually has helical feed marks and this causes the workpiece to become more susceptible to corrosion and crack propagation at the stressed surface. A finish operation may be done to avoid these detrimental conditions, for fluted drill bits, any chips are removed via the flutes. Chips may form long spirals or small flakes, depending on the material, the type of chips formed can be an indicator of the machinability of the material, with long chips suggesting poor material machinability. When possible drilled holes should be located perpendicular to the workpiece surface and this minimizes the drill bits tendency to walk, that is, to be deflected from the intended center-line of the bore, causing the hole to be misplaced. The higher the ratio of the drill bit, the greater the tendency to walk. Constraining the position of the drill bit using a jig with drill bushings Surface finish produced by drilling may range from 32 to 500 microinches. Finish cuts will generate surfaces near 32 microinches, and roughing will be near 500 microinches, cutting fluid is commonly used to cool the drill bit, increase tool life, increase speeds and feeds, increase the surface finish, and aid in ejecting chips. Application of these fluids is usually done by flooding the workpiece with coolant and lubricant or by applying a spray mist, in deciding which drill to use it is important to consider the task at hand and evaluate which drill would best accomplish the task. There are a variety of styles that each serve a different purpose. The subland drill is capable of drilling more than one diameter, the spade drill is used to drill larger hole sizes. The indexable drill is useful in managing chips, the purpose of spot drilling is to drill a hole that will act as a guide for drilling the final hole. The hole is only drilled part way into the workpiece because it is used to guide the beginning of the next drilling process

Manufacturing
–
Manufacturing is the value added to production of merchandise for use or sale using labour and machines, tools, chemical and biological processing, or formulation. Manufacturing engineering or manufacturing process are the steps through which raw materials are transformed into a final product, the manufacturing process begins with the product design, and materials specification from which the product is made. These materials are modified through manufacturing processes to become the required part. Manufacturing takes turns under all types of economic systems, in a free market economy, manufacturing is usually directed toward the mass production of products for sale to consumers at a profit. In a collectivist economy, manufacturing is more directed by the state to supply a centrally planned economy. In mixed market economies, manufacturing occurs under some degree of government regulation, modern manufacturing includes all intermediate processes required the production and integration of a products components. Some industries, such as semiconductor and steel manufacturers use the term fabrication instead, the manufacturing sector is closely connected with engineering and industrial design. Examples of major manufacturers in North America include General Motors Corporation, General Electric, Procter & Gamble, General Dynamics, Boeing, Pfizer, examples in Europe include Volkswagen Group, Siemens, and Michelin. Examples in Asia include Sony, Huawei, Lenovo, Toyota, Samsung, in its earliest form, manufacturing was usually carried out by a single skilled artisan with assistants. In much of the world, the guild system protected the privileges. Before the Industrial Revolution, most manufacturing occurred in rural areas, entrepreneurs organized a number of manufacturing households into a single enterprise through the putting-out system. Toll manufacturing is an arrangement whereby a first firm with specialized equipment processes raw materials or semi-finished goods for a second firm, manufacturing provides important material support for national infrastructure and for national defense. On the other hand, most manufacturing may involve significant social and environmental costs, the clean-up costs of hazardous waste, for example, may outweigh the benefits of a product that creates it. Hazardous materials may expose workers to health risks and these costs are now well known and there is effort to address them by improving efficiency, reducing waste, using industrial symbiosis, and eliminating harmful chemicals. The negative costs of manufacturing can also be addressed legally, developed countries regulate manufacturing activity with labor laws and environmental laws. Across the globe, manufacturers can be subject to regulations and pollution taxes to offset the costs of manufacturing activities. Labor unions and craft guilds have played a role in the negotiation of worker rights. Environment laws and labor protections that are available in developed nations may not be available in the third world, tort law and product liability impose additional costs on manufacturing

Texas
–
Texas is the second largest state in the United States by both area and population. Other major cities include Austin, the second most populous state capital in the U. S. Texas is nicknamed the Lone Star State to signify its former status as an independent republic, and as a reminder of the states struggle for independence from Mexico. The Lone Star can be found on the Texan state flag, the origin of Texass name is from the word Tejas, which means friends in the Caddo language. Due to its size and geologic features such as the Balcones Fault, although Texas is popularly associated with the U. S. southwestern deserts, less than 10 percent of Texas land area is desert. Most of the centers are located in areas of former prairies, grasslands, forests. Traveling from east to west, one can observe terrain that ranges from coastal swamps and piney woods, to rolling plains and rugged hills, the term six flags over Texas refers to several nations that have ruled over the territory. Spain was the first European country to claim the area of Texas, Mexico controlled the territory until 1836 when Texas won its independence, becoming an independent Republic. In 1845, Texas joined the United States as the 28th state, the states annexation set off a chain of events that caused the Mexican–American War in 1846. A slave state before the American Civil War, Texas declared its secession from the U. S. in early 1861, after the Civil War and the restoration of its representation in the federal government, Texas entered a long period of economic stagnation. One Texan industry that thrived after the Civil War was cattle, due to its long history as a center of the industry, Texas is associated with the image of the cowboy. The states economic fortunes changed in the early 20th century, when oil discoveries initiated a boom in the state. With strong investments in universities, Texas developed a diversified economy, as of 2010 it shares the top of the list of the most Fortune 500 companies with California at 57. With a growing base of industry, the leads in many industries, including agriculture, petrochemicals, energy, computers and electronics, aerospace. Texas has led the nation in export revenue since 2002 and has the second-highest gross state product. The name Texas, based on the Caddo word tejas meaning friends or allies, was applied by the Spanish to the Caddo themselves, during Spanish colonial rule, the area was officially known as the Nuevo Reino de Filipinas, La Provincia de Texas. Texas is the second largest U. S. state, behind Alaska, though 10 percent larger than France and almost twice as large as Germany or Japan, it ranks only 27th worldwide amongst country subdivisions by size. If it were an independent country, Texas would be the 40th largest behind Chile, Texas is in the south central part of the United States of America. Three of its borders are defined by rivers, the Rio Grande forms a natural border with the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas to the south

Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

Howard Hughes
–
Howard Robard Hughes Jr. was an American businessman, investor, pilot, film director, and philanthropist, known during his lifetime as one of the most financially successful individuals in the world. He first made a name for himself as a film producer, later in life, he became known for his eccentric behavior and reclusive lifestyle, oddities that were caused in part by a worsening obsessive–compulsive disorder and chronic pain from a plane crash. As a maverick film tycoon, Hughes gained prominence in Hollywood beginning in the late 1920s, when he made big-budget and often controversial films like The Racket, Hells Angels, later he controlled the RKO film studio. Hughes formed the Hughes Aircraft Company in 1932, hiring numerous engineers and designers and he spent the rest of the 1930s setting multiple world air speed records and building the Hughes H-1 Racer and H-4 Hercules. He acquired and expanded Trans World Airlines and later acquired Air West, Hughes was included in Flying Magazines list of the 51 Heroes of Aviation, ranked at No.25. Today, his legacy is maintained through the Howard Hughes Medical Institute, the birthplace of Howard Hughes is recorded as either Humble or Houston, Texas. The date remains uncertain due to conflicting dates from various sources and he repeatedly claimed that his birthday was on Christmas Eve. A1941 affidavit birth certificate of Hughes that was signed by his aunt Annette Gano Lummis and Estelle Boughton Sharp states that he was born on December 24,1905, in Harris County, Texas. Hughes was the son of Allene Stone Gano and Howard R. Hughes Sr. a successful inventor and he was of English, and some French Huguenot, ancestry, and was a descendant of John Gano, a minister who allegedly baptized George Washington. His father had patented the two-cone roller bit, which allowed rotary drilling for petroleum in previously inaccessible places, the senior Hughes made the shrewd and lucrative decision to commercialize the invention by leasing the bits instead of selling them, and founded the Hughes Tool Company in 1909. Hughes uncle was the famed novelist, screenwriter, and film director Rupert Hughes, at a young age, Hughes demonstrated interest in science and technology. In particular, he had great engineering aptitude and built Houstons first wireless radio transmitter at age 11 and he went on to be one of the first licensed ham radio operators in Houston, having the assigned callsign W5CY. At 12, Hughes was photographed in the newspaper, identified as being the first boy in Houston to have a motorized bicycle. He was an indifferent student, with a liking for mathematics, flying and he took his first flying lesson at 14, and later attended math and aeronautical engineering courses at Caltech. The red brick house where Hughes lived as a teenager at 3921 Yoakum St. Houston today serves as the headquarters of the Theology Department of the University of St. Thomas and his mother Allene died in March 1922 from complications of an ectopic pregnancy. Howard Hughes Sr. died of an attack in 1924. Their deaths apparently inspired Hughes to include the creation of a research laboratory in the will that he signed in 1925 at age 19. Howard Sr. s will had not been updated since Allenes death, on his 19th birthday, Hughes was declared an emancipated minor, enabling him to take full control of his life

Drill bit
–
Drill bits are cutting tools used to remove material to create holes, almost always of circular cross-section. Drill bits come in sizes and shape and can create different kinds of holes in many different materials. In order to create holes drill bits are attached to a drill, the drill will grasp the upper end of a bit called the shank in the chuck. Drill bits come in sizes, described in the drill bit sizes article. A comprehensive drill bit and tap size chart lists metric and imperial sized drill bits alongside the required screw tap sizes, there are also certain specialized drill bits that can create holes with a non-circular cross-section. While the term drill may refer to either a machine or a drill bit for use in a drilling machine. In this article, for clarity, drill bit or bit is used throughout to refer to a bit for use in a drilling machine, Drill bit geometry has several characteristics, The spiral in the drill bit controls the rate of chip removal. A fast spiral drill bit is used in high feed rate applications under low spindle speeds, the point angle, or the angle formed at the tip of the bit, is determined by the material the bit will be operating in. Harder materials require a larger point angle, and softer materials require a sharper angle, the correct point angle for the hardness of the material influences wandering, chatter, hole shape, and wear rate. The lip angle determines the amount of support provided to the cutting edge, a greater lip angle will cause the bit to cut more aggressively under the same amount of point pressure as a bit with a smaller lip angle. Both conditions can cause binding, wear, and eventual failure of the tool. The proper amount of lip clearance is determined by the point angle, the length of a bit determines how deep a hole can be drilled, and also determines the stiffness of the bit and accuracy of the resultant hole. While longer bits can drill deeper holes, they are flexible meaning that the holes they drill may have an inaccurate location or wander from the intended axis. Twist drill bits are available in lengths, referred to as Stub-length or Screw-Machine-length, the extremely common Jobber-length. Most drill bits for use have straight shanks. For heavy duty drilling in industry, bits with tapered shanks are sometimes used, other types shanks used include hex-shaped, and various proprietary quick release systems. The diameter-to-length ratio of the bit is usually between 1,1 and 1,10. Much higher ratios are possible, but the higher the ratio, the best geometry to use depends upon the properties of the material being drilled

Drilling rig
–
A drilling rig is a machine that creates holes in the earth sub-surface. Drilling rigs can be mobile equipment mounted on trucks, tracks or trailers, the term rig therefore generally refers to the complex of equipment that is used to penetrate the surface of the Earths crust. Small to medium-sized drilling rigs are mobile, such as used in mineral exploration drilling, blast-hole, water wells. Hoists in the rig can lift hundreds of tons of pipe, other equipment can force acid or sand into reservoirs to facilitate extraction of the oil or natural gas, and in remote locations there can be permanent living accommodation and catering for crews. Marine rigs may operate thousands of miles distant from the base with infrequent crew rotation or cycle. Oil and natural gas drilling rigs are used not only to identify geologic reservoirs and this frees up the drilling rig to drill another hole and streamlines the operation as well as allowing for specialization of certain services, i. e. completions vs. drilling. New portable drillcat technology uses smaller portable trailer mounted rigs with shorter 3-metre drill pipe, the shorter drill pipe also allows a much smaller mast. Portable trailer mounted drilling rigs have drill ratings from 90 to 200 metres depending on mud pump flow and pressure ratings, other, heavier, truck rigs are more complicated, thus requiring more skill to run. Theyre also more difficult to handle due to the longer 6-to-9-metre drill pipe. Large truck rigs also require a much higher overhead clearance to operate, large truck drills can use over 570 litres of fuel per day, while the smaller Deeprock Style portable drills use a mere 20 to 75 litres of fuel per day. This makes smaller, more portable rigs preferable in remote or hard-to-reach places, Drilling rigs used for rock blasting for surface mines vary in size dependent on the size of the hole desired, and is typically classified into smaller pre-split and larger production holes. Underground mining uses a variety of drill rigs dependent on the purpose, such as production, bolting, cabling. Until internal combustion engines were developed in the late 19th century, the drilling of wells for the manufacture of salt began by the Song Dynasty in China. The well had a small mouth, as small as a small bowl. Archaeological evidence of the tools used in deep-well dwelling are kept. According to Salt, A World History, a Qing Dynasty well, also located in Zigong, diamond drilling has remained essentially unchanged since its inception. In early oil exploration, drilling rigs were semi-permanent in nature, in more recent times drilling rigs are expensive custom-built machines that can be moved from well to well. Some light duty drilling rigs are like a crane and are more usually used to drill water wells

Rice University
–
William Marsh Rice University, commonly referred to as Rice University or Rice, is a private research university located on a 295-acre campus in Houston, Texas, United States. The university is situated near the Houston Museum District and is adjacent to the Texas Medical Center, Rice is generally considered the top university and the most selective institute of higher education in the state of Texas. Opened in 1912 after the murder of its namesake William Marsh Rice, Rice is now a university with an undergraduate focus. Its emphasis on education is demonstrated by a student body and 6,1 student-faculty ratio. The university has a high level of research activity for its size. Rice is noted for its science programs in the fields of artificial heart research, structural chemical analysis, signal processing, space science. It was ranked first in the world in materials science research by the Times Higher Education in 2010, Rice is a member of the Association of American Universities. Graduate programs are offered through the Jesse H. Jones Graduate School of Business, School of Architecture, Shepherd School of Music, Rice students are bound by the strict Honor Code, which is enforced by a student-run Honor Council. Rice competes in 14 NCAA Division I varsity sports and is a part of Conference USA, intramural and club sports are offered in a wide variety of activities such as jiu jitsu, water polo, and crew. In 1891, Rice decided to charter a free-tuition educational institute in Houston, bearing his name, to be created upon his death, Rices will specified the institution was to be a competitive institution of the highest grade and that only white students would be permitted to attend. On the morning of September 23,1900, Rice, age 84, was dead by his valet. Shortly thereafter, a large check made out to Rices New York City lawyer. The lawyer, Albert T. Patrick, then announced that Rice had changed his will to leave the bulk of his fortune to Patrick, rather than to the creation of Rices educational institute. Rices friend and personal lawyer in Houston, James A. Baker, Jones was not prosecuted since he cooperated with the district attorney, and testified against Patrick. Patrick was found guilty of conspiring to steal Rices fortune and convicted of murder in 1901, Baker helped Rices estate direct the fortune, worth $4.6 million in 1904, towards the founding of what was to be called the Rice Institute. The board took control of the assets on April 29 of that year and he came recommended by Princetons president, Woodrow Wilson. In 1908, Lovett accepted the challenge, and was inaugurated as the Institutes first president on October 12,1912. Lovett undertook extensive research before formalizing plans for the new Institute, Lovett called for the establishment of a university of the highest grade, an institution of liberal and technical learning devoted quite as much to investigation as to instruction

RKO Pictures
–
RKO Pictures Inc. also known as RKO Radio Pictures and in its later years RKO Teleradio Pictures, was an American film production and distribution company. It was one of the Big Five studios of Hollywoods Golden Age, RCA chief David Sarnoff engineered the merger to create a market for the companys sound-on-film technology, RCA Photophone. By the mid-1940s, the studio was under the control of investor Floyd Odlum, RKO has long been celebrated for its series of musicals starring Fred Astaire and Ginger Rogers in the mid-to-late 1930s. Actors Katharine Hepburn and, later, Robert Mitchum had their first major successes at the studio, cary Grant was a mainstay for years. The work of producer Val Lewtons low-budget horror unit and RKOs many ventures into the now known as film noir have been acclaimed, largely after the fact, by film critics. The studio produced two of the most famous films in motion picture history, King Kong and Citizen Kane, RKO Pictures is also a member of Motion Picture Association of America. Maverick industrialist Howard Hughes took over RKO in 1948, after years of turmoil and decline under his control, Hughes sold the troubled studio to General Tire and Rubber Company in 1955. The original RKO Pictures ceased production in 1957 and was dissolved two years later. In 1981, broadcaster RKO General, the heir, revived it as a production subsidiary. In October 1927, Warner Bros. released The Jazz Singer and its success prompted Hollywood to convert from silent to sound film production en masse. The Radio Corporation of America controlled an advanced optical sound-on-film system, RCA Photophone, the industrys two largest major studios, Paramount and Loews/MGM, with two other studios Universal and First National, were poised to contract with ERPI for sound conversion as well. Next on the agenda was securing a string of exhibition venues like those the leading Hollywood production companies owned, Kennedy began investigating the possibility of such a purchase. Around that time, the large Keith-Albee-Orpheum circuit of theaters, built around the medium of live vaudeville, was attempting a transition to the movie business. In mid-1927, the operations of Pathé Exchange and Cecil B. De Milles Producers Distributing Corporation had united under KAOs control, early in 1928, KAO general manager John J. Murdock, who had assumed the presidency of Pathé, turned to Kennedy as an adviser in consolidating the studio with De Milles company, PDC. This was the relationship Sarnoff and Kennedy sought, on October 23,1928, RCA announced the creation of the Radio-Keith-Orpheum holding company, with Sarnoff as chairman of the board. Kennedy, who withdrew from his positions in the merged companies, kept Pathé separate from RKO. RCA owned the governing stock interest in RKO,22 percent, in the early 1930s, the companys production and distribution arm, presided over by former FBO vice-president Joseph I
