A shoe is an item of footwear intended to protect and comfort the human foot. Though the human foot can adapt to varied terrains and climate conditions, it is vulnerable, and shoes provide protection. Form was originally tied to function but over time shoes also became fashion items. Some shoes are worn as safety equipment, such as steel-toe boots, which are required footwear at industrial worksites.
A tape drive is a data storage device that reads and writes data on a magnetic tape. Magnetic-tape data storage is typically used for offline, archival data storage. Tape media generally has a favorable unit cost and a long archival stability.
An oil well is a drillhole boring in Earth that is designed to bring petroleum oil hydrocarbons to the surface. Usually some natural gas is released as associated petroleum gas along with the oil. A well that is designed to produce only gas may be termed a gas well. Wells are created by drilling down into an oil or gas reserve that is then mounted with an extraction device such as a pumpjack which allows extraction from the reserve. Creating the wells can be an expensive process, costing at least hundreds of thousands of dollars, and costing much more when in hard to reach areas, e.g., when creating offshore oil platforms. The process of modern drilling for wells first started in the 19th century, but was made more efficient with advances to oil drilling rigs during the 20th century.
A pumpjack is the overground drive for a reciprocating piston pump in an oil well.
A grommet is a ring or edge strip inserted into a hole through thin material, typically a sheet of textile fabric, sheet metal or composite of carbon fiber, wood or honeycomb. Grommets are generally flared or collared on each side to keep them in place, and are often made of metal, plastic, or rubber. They may be used to prevent tearing or abrasion of the pierced material or protection from abrasion of the insulation on the wire, cable, line being routed through the penetration, and to cover sharp edges of the piercing, or all of the above.
Shoemaking is the process of making footwear.
Reuben Carlton "Carl" Baker, Sr. was an American oil industry drilling pioneer. He established Baker Oil Tools in 1907 after developing a casing shoe that revolutionized cable tool drilling. In 1903, he introduced the offset bit for cable tool drilling to enable casing wells in hard rock and in 1912 the cement retainer that allowed casing to be cemented in the wells. Baker further improved the process with the float shoe in 1923. Having only a third grade education, he obtained more than 150 patents on oil drilling tools. Baker Oil Tools merged with Hughes Tool Company in 1987 to form Baker Hughes Incorporated.
Cycling shoes are shoes purpose-built for cycling. There are a variety of designs depending on the type and intensity of the cycling for which they are intended. Key features include rigidity, for more-efficient transfer of power from the cyclist to the pedals, weight, a method of attaching the shoe firmly to the pedal and adaptability for use on and off the bicycle. Most high-performance cycling shoes can be adjusted while in use, via a quick-adjusting system that has largely replaced laces.
Casing is a large diameter pipe that is assembled and inserted into a recently drilled section of a borehole. Similar to the bones of a spine protecting the spinal cord, casing is set inside the drilled borehole to protect and support the wellstream. The lower portion is typically held in place with cement. Deeper strings usually are not cemented all the way to the surface, so the weight of the pipe must be partially supported by a casing hanger in the wellhead.
A Goodyear welt is a strip of leather, rubber, or plastic that runs along the perimeter of a shoe outsole. The basic principle behind the Goodyear welt machine was invented in 1862 by August Destouy who designed a machine with a curved needle to stitch turned shoes. The machine was then improved in 1869 and later by Destouy and, more importantly, Daniel Mills, an English mechanic, both employed by Charles Goodyear Jr., the son of Charles Goodyear. It has been noted by historians that Goodyear was a frequent visitor to the shoe factory of William J. Dudley, founder of Johnston & Murphy, where early work on sole stitching equipment was performed.
A wellhead is the component at the surface of an oil or gas well that provides the structural and pressure-containing interface for the drilling and production equipment.
A ballet shoe, or ballet slipper, is a lightweight shoe designed specifically for ballet dancing. It may be made from soft leather, canvas, or satin, and has flexible, thin full or split soles. Traditionally, women wear pink shoes and men wear white or black shoes. Skin-colored slippers—which are unobtrusive and thus give the appearance of dancing barefoot—are worn in modern ballets and sometimes modern dancing by both men and women.
The Bali catshark is a species of catshark, belonging to the family Scyliorhinidae, found only off the Indonesian island of Bali. It can grow up to 47 cm (19 in). Atelomycterus baliensis inhabits the deep coastal waters of Bali, Indonesia, feeding on small fish and invertebrates.
Pipe ramming is a trenchless method for installation of steel pipes and casings. Distances of 30 m or more and over 500 mm in diameter are common, although the method can be used for much longer and larger installations. The method is useful for pipe and casing installations under railway lines and roads, where other trenchless methods could cause subsidence or heaving. The majority of installations are horizontal, although the method can be used for vertical installations.
Maximum Allowable Annulus Surface Pressure is an absolute upper limit for the pressure in the annulus of an oil and gas well as measured at the wellhead.
Brigadier General (BGen) (Swedish: Brigadgeneral, Bgen) is a one-star commissioned officer rank in the Swedish Army, Swedish Air Force and Swedish Amphibious Corps. A Brigadier general ranks immediately above a colonel and below a major general. The rank is equivalent to rear admiral (lower half) in the Swedish Navy.
Well completion is the process of making a well ready for production after drilling operations. This principally involves preparing the bottom of the hole to the required specifications, running in the production tubing and its associated down hole tools as well as perforating and stimulating as required. Sometimes, the process of running in and cementing the casing is also included. After a well has been drilled, should the drilling fluids be removed, the well would eventually close in upon itself. Casing ensures that this will not happen while also protecting the wellstream from outside incumbents, like water or sand.
Drum hardware is the set of parts of a drum or drum kit that are used to tension, position, and otherwise support the instruments themselves.
Jaguar's independent rear suspension (IRS) unit has been a common component of a number of Jaguar production cars since 1961, passing through two major changes of configuration up to 2006 and last used in the Jaguar XK8 and Aston Martin DB7. This article concentrates on the first generation Jaguar IRS, which firmly established the marque's reputation for suspension sophistication, combining as it did smooth ride with excellent roadholding and low levels of noise, vibration, and harshness (NVH). The two generations overlap in time due to their being used in both full size and sports models that were updated at different times.
Oil Well Cementing Equipment are essential for the Oil/Gas exploration or production wells and are must used oilfield equipments while drilling a well.
