Powder Measure
A powder measure is a device for dispensing consistent amounts of smokeless powder or black powder as charges for handloading cartridges used as small arms ammunition. Propellant evolution Firearms using gunpowder could be loaded using a small scoop or charge cup to determine the correct amount for each shot. Some early smokeless propellants called bulk propellants were designed for a similar volume and reaction rate as gunpowder, but most modern smokeless powders have improved efficiency offering more energy from smaller charges. This improved efficiency allows smaller cartridges for increased ammunition capacity. Modern smokeless propellants come in a wide variety of shapes, density, reaction rates, and energy to weight relationships. Similar volumes of different smokeless propellants may produce dangerously different pressures in the same cartridge. Dispenser design Adjustable powder measures became available in the 1880s. One of the earliest was designed by John M. Barlow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ivory Powder Measure - DPLA - Eaab2fc72b4fb9a1d2c4b7a5d31bffd1 (cropped)
Ivory is a hard, white material from the tusks (traditionally from elephants) and teeth of animals, that consists mainly of dentine, one of the physical structures of teeth and tusks. The chemical structure of the teeth and tusks of mammals is the same, regardless of the species of origin, but ivory contains structures of mineralised collagen. The trade in certain teeth and tusks other than elephant is well established and widespread; therefore, "ivory" can correctly be used to describe any mammalian teeth or tusks of commercial interest which are large enough to be carved or scrimshawed. Besides natural ivory, ivory can also be produced synthetically, hence (unlike natural ivory) not requiring the retrieval of the material from animals. Tagua nuts can also be carved like ivory. The trade of finished goods of ivory products has its origins in the Indus Valley. Ivory is a main product that is seen in abundance and was used for trading in Harappan civilization. Finished ivory pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vibration
Vibration () is a mechanical phenomenon whereby oscillations occur about an equilibrium point. Vibration may be deterministic if the oscillations can be characterised precisely (e.g. the periodic motion of a pendulum), or random if the oscillations can only be analysed statistically (e.g. the movement of a tire on a gravel road). Vibration can be desirable: for example, the motion of a tuning fork, the reed in a woodwind instrument or harmonica, a mobile phone, or the cone of a loudspeaker. In many cases, however, vibration is undesirable, wasting energy and creating unwanted sound. For example, the vibrational motions of engines, electric motor An electric motor is a 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 gene ...s, or any Machine, mechanical device in operation are typically unwanted. ...

Bend, Oregon
Bend is a city in central Oregon and the county seat of Deschutes County, Oregon, Deschutes County, Oregon, United States. It is located to the east of the Cascade Range, on the Deschutes River. The site became known by pioneers as a ford (crossing), fordable crossing point of the river, where it ran through a bend. An 1870s ranch popularized the name "Farewell Bend", with the post office later distinguishing the area as Bend. It was incorporated as a city in 1905, starting off as a logging town. In 1910, Mirror Pond was created as a dammed river reservoir to provide energy. In 1950, the two major logging companies were consolidated due to depleted timber, causing an economic drop. In later decades, it experienced rapid growth as a center of recreation. Situated in the High Desert (Oregon), high desert, Bend is bordered by the Deschutes National Forest to the southwest. Economically, it is a tourist destination, featuring recreational attractions (e.g. breweries, Hayden Homes Am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Olin Corporation
Olin Corporation is an American manufacturer of ammunition, chlorine, and sodium hydroxide. The company traces its roots to two companies, both founded in 1892: Franklin W. Olin's Equitable Powder Company and the Mathieson Alkali Works. Accidents at Olin chemical plants have exposed employees and nearby residents to health hazards.

Improved Military Rifle Powder
Improved military rifle propellants are tubular nitrocellulose propellants evolved from World War I through World War II for loading military and commercial ammunition and sold to civilians for reloading rifle ammunition for hunting and target shooting. These propellants were DuPont modifications of United States artillery propellants.Davis pp.296&297 DuPont miniaturized the large artillery grains to form military rifle propellants suitable for use in small arms. These were improved during the First World War to be more efficient in rimless military cartridges replacing earlier rimmed rifle cartridges. Four-digit numbers identified experimental propellants, and a few successful varieties warranted extensive production by several manufacturers. Some were used almost exclusively for military contracts, or commercial ammunition production, but a few have been distributed for civilian use in handloading. Improved military rifle propellants are coated with dinitrotoluene (DNT) to slow ini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ball Propellant
Ball propellant (trademarked as Ball Powder by Olin Corporation and marketed as spherical powder by Hodgdon Powder CompanyWootters, John ''Propellant Profiles'' (1982) Wolfe Publishing Company pp.95,101,136-138,141,149&155 ) is a form of nitrocellulose used in small arms cartridges. Ball propellant can be manufactured more rapidly with greater safety and less expense than extruded propellants. Ball propellant was first used to load military small arms cartridges during World War II and has been manufactured for sale to handloading civilians since 1960. History The United States military replaced black powder during the first decade of the 20th century with smokeless powders formulated from nitrocellulose colloided with ether and alcohol. Large quantities were manufactured for World War I and significant amounts remained unused after the war. Nitrocellulose deteriorates in storage, but military quantities of old smokeless propellant were sometimes reworked into new lots of pr ...
