Shanti Lal Khanna
Shanti Lal Khanna (d. c. 1980s) was an Indian businessman and doctor. Khanna was born in the Punjab Province, British India. He initially established a dental practice before founding a business in Lahore with interests in the travel and agriculture industries. In 1939, Khanna founded a manufacturing company that became the sole authorized manufacturer of weights and measures in the Punjab Province. After the Partition of India in 1947, Khanna resettled in Delhi. Although he lost his earlier wealth during the Partition, he later founded Delhi Small Scale Industries in the 1950s. The company manufactured various products and also had an import-export business. He also held positions on the Bureau of Indian Standards' product specification committees, leadership posts in textile associations, and was a high-ranking Freemason. Khanna died at an unknown date in the 1980s. He was the first notable member of the Khanna family. Background and early career Shanti Lal Khanna was ...

Punjab Province (British India)
Punjab was a province of British India. Most of the Punjab region was annexed by the East India Company in 2 April 1849, and declared a province of British Rule, it was one of the last areas of the Indian subcontinent to fall under British control. In 1858, the Punjab, along with the rest of British India, came under the direct rule of the British Crown. It had an area of 358,354.5 km2. The province comprised four natural geographic regions – ''Indo-Gangetic Plain West'', ''Himalayan'', ''Sub-Himalayan'', and the ''North-West Dry Area'' – along with five administrative divisions – Delhi, Jullundur, Lahore, Multan, and Rawalpindi – and a number of princely states. In 1947, the Partition of India led to the province's division into East Punjab and West Punjab, in the newly independent dominions of India and Pakistan respectively.

Okhla
Okhla is a suburban village located near Okhla barrage in the South East Delhi district of Delhi near the border between Delhi and Uttar Pradesh. Its nearest industrial area called commonly as Okhla Industrial Area (OIA) or Okhla Industrial Estate, an industrial suburb in South Delhi which is mainly divided into three Phases. It stands for Old Kanal Housing and Land Authority (Kanal was used instead of canal since "ch" in the abbreviated form would have been pronounced differently). Okhla has lent its name to the nearby planned township of New Okhla Industrial Development Authority or NOIDA. Okhla is also an assembly constituency. About Okhla is one of the oldest villages in Delhi near the bank of Yamuna River. This can be judged from the making of Okhla canal (Agra Canal) by Britishers in 1874, presently known as Okhla Head. History The Okhla barrage, is a barrage, which was developed by British, is also the starting point of the Agra Canal built in 1874, today it is also t ...

Carbon Steel
Carbon steel is a steel with carbon content from about 0.05 up to 2.1 percent by weight. The definition of carbon steel from the American Iron and Steel Institute (AISI) states: * no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium, zirconium, or any other element to be added to obtain a desired alloying effect; * the specified minimum for copper does not exceed 0.40%; * or the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65%; silicon 0.60%; copper 0.60%. The term ''carbon steel'' may also be used in reference to steel which is not stainless steel; in this use carbon steel may include alloy steels. High carbon steel has many different uses such as milling machines, cutting tools (such as chisels) and high strength wires. These applications require a much finer microstructure, which improves the toughness. Carbon steel is a popular metal choic ...

Electric Motor
An electric motor is an Electric machine, electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a Electromagnetic coil, wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy. Electric motors can be powered by direct current (DC) sources, such as from batteries, or rectifiers, or by alternating current (AC) sources, such as a power grid, Inverter (electrical), inverters or electrical generators. Electric motors may be classified by considerations such as power source type, construction, application and type of motion output. They can be powered by AC or DC, be Brushed motor, brushed or Brushless motor, brushless, single-phase, Two-phase electric power, two-p ...

Reduction Drive
A reduction drive is a mechanical device to shift rotational speed. A planetary reduction drive is a small scale version using ball bearings in an epicyclic arrangement instead of toothed gears. Reduction drives are used in engines of all kinds to increase the amount of torque per revolution of a shaft: the gearbox of any car is a ubiquitous example of a reduction drive. Common household uses are washing machines, food blenders and window-winders. Reduction drives are also used to decrease the rotational speed of an input shaft to an appropriate output speed. Reduction drives can be a gear train design or belt driven. Planetary reduction drives are typically attached between the shaft of the variable capacitor and the tuning knob of any radio, to allow fine adjustments of the tuning capacitor with smooth movements of the knob. Planetary drives are used in this situation to avoid "backlash", which makes tuning easier. If the capacitor drive has backlash, when one attempts to tune i ...

Wire
Overhead power cabling. The conductor consists of seven strands of steel (centre, high tensile strength), surrounded by four outer layers of aluminium (high conductivity). Sample diameter 40 mm A wire is a flexible strand of metal. Wire is commonly formed by drawing the metal through a hole in a die or draw plate. Wire gauges come in various standard sizes, as expressed in terms of a gauge number. Wires are used to bear mechanical loads, often in the form of wire rope. In electricity and telecommunications signals, a "wire" can refer to an electrical cable, which can contain a "solid core" of a single wire or separate strands in stranded or braided forms. Usually cylindrical in geometry, wire can also be made in square, hexagonal, flattened rectangular, or other cross-sections, either for decorative purposes, or for technical purposes such as high-efficiency voice coils in loudspeakers. Edge-wound coil springs, such as the Slinky toy, are made of special flatten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bronze
Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals, such as phosphorus, or metalloids such as arsenic or silicon. These additions produce a range of alloys that may be harder than copper alone, or have other useful properties, such as ultimate tensile strength, strength, ductility, or machinability. The three-age system, archaeological period in which bronze was the hardest metal in widespread use is known as the Bronze Age. The beginning of the Bronze Age in western Eurasia and India is conventionally dated to the mid-4th millennium BCE (~3500 BCE), and to the early 2nd millennium BCE in China; elsewhere it gradually spread across regions. The Bronze Age was followed by the Iron Age starting from about 1300 BCE and reaching most of Eurasia by about 500 BCE, although bronze continued to be much more widely used than it is in mod ...

Rolling-element Bearing
In mechanical engineering, a rolling-element bearing, also known as a rolling bearing, is a bearing which carries a load by placing rolling elements (such as balls or rollers) between two concentric, grooved rings called races. The relative motion of the races causes the rolling elements to roll with very little rolling resistance and with little sliding. One of the earliest and best-known rolling-element bearings are sets of logs laid on the ground with a large stone block on top. As the stone is pulled, the logs roll along the ground with little sliding friction. As each log comes out the back, it is moved to the front where the block then rolls on to it. It is possible to imitate such a bearing by placing several pens or pencils on a table and placing an item on top of them. See " bearings" for more on the historical development of bearings. A rolling element rotary bearing uses a shaft in a much larger hole, and cylinders called "rollers" tightly fill the space between t ...

Pile (textile)
Pile is the raised surface or nap of a fabric, consisting of upright loops or strands of yarn."Pile." ''The Oxford English Dictionary''. 2nd ed. 1989. Examples of pile textiles are carpets, corduroy, velvet, plush, and Turkish towels. The word is derived from Latin ''pilus'' for "hair". " Online Etymology Dictionary. Douglas Harper, Historian. retrieved from 10 September 2007. Length and density The surface and the yarn in these fabrics are also called "pile". In particular "pile length" or "pile depth" refer to the length of the yarn strands (half-length of the loops). Pile length affects and is affected by |
Blanket
A blanket is a swath of soft cloth large enough either to cover or to enfold most of the user's body and thick enough to keep the body warm by trapping radiant body heat that otherwise would be lost through convection. Etymology The term arose from the generalization of a specific fabric called ''Blanket fabric'', a heavily napped woolen weave pioneered by Thomas Blanket (Blanquette), a Flemish weaver who lived in Bristol, England, in the 14th century. Earlier usage of the term is possible through its derivation from the French word for white: . According to the Oxford English Dictionary, the word was used a noun as long ago as the 14th century. William Shakespeare is recognised as the first person to use the verb ''blanket'', meaning to 'cover with or as with a blanket'. In the play ''King Lear'', published in 1608, the character Edgar says: "My face ile grime with filth, Blanket my loynes, else all my haire with knots." History An ancient form of blanket is recor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Metal Fabrication
Metal fabrication is the creation of metal structures by cutting, bending and assembling processes. It is a value-added process involving the creation of machines, parts, and structures from various raw materials. Typically, a fabrication shop bids on a job, usually based on engineering drawings, and if awarded the contract, builds the product. Large fab shops employ a multitude of value-added processes, including welding, cutting, forming and machining. As with other manufacturing processes, both human labor and automation are commonly used. A fabricated product may be called a ''fabrication'', and shops specializing in this type of work are called ''fab shops''. The end products of other common types of metalworking, such as machining, metal stamping, forging, and casting, may be similar in shape and function, but those processes are not classified as fabrication. Processes *''Cutting'' is done by sawing, shearing, or chiselling (all with manual and powered variants); ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
