American Powder Mills
American Powder Mills (1883–1929) was a Massachusetts gunpowder manufacturing complex on the Assabet River. It expanded to include forty buildings along both sides of the river in the towns of Acton, Massachusetts, Acton, Concord, Massachusetts, Concord, Maynard, Massachusetts, Maynard, and Sudbury, Massachusetts, Sudbury. Press mills, kernelling mills, glazing mills, and storehouses were dispersed over four-hundred acres to minimize damage during explosions. A narrow gauge railway transferred raw materials and products between the buildings. History Nathan Pratt purchased a mill pond dam on the Assabet River and converted the former sawmill to a powder mill in 1835. Pratt sold the mill to the American Powder Company in 1864. The mill manufactured of gunpowder per day through the American civil war. In 1872 American Powder Company joined the United States Gunpowder Trade Association, popularly known as the Trust (monopoly), powder trust, with Austin Powder Company, DuPont, Haza ...

Privately Held Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or Over-the-counter (finance), over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their public company, publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''. In 2005, using a substantially smaller pool size (22.7%) for comparison, the 339 companies on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trust (monopoly)
A trust or corporate trust is a large grouping of business interests with significant market power, which may be embodied as a corporation or as a group of corporations that cooperate with one another in various ways. These ways can include constituting a trade association, owning stock in one another, constituting a corporate group (sometimes specifically a conglomerate), or combinations thereof. The term ''trust'' is often used in a historical sense to refer to monopolies or near-monopolies in the United States during the Second Industrial Revolution in the 19th century and early 20th century. The use of corporate trusts during this period is the historical reason for the name "antitrust law". In the broader sense of the term, relating to trust law, a trust is a centuries-old legal arrangement whereby one party conveys legal possession and title of certain property to a second party, called a trustee. While that trustee has ownership, they cannot use the property for herself, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Explosives Manufacturers
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or BLEVE * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are said to be "low explosives". Explosives may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ammunition Manufacturers
Ammunition (informally ammo) is the material fired, scattered, dropped, or detonated from any weapon or weapon system. Ammunition is both expendable weapons (e.g., bombs, missiles, grenades, land mines) and the component parts of other weapons that create the effect on a target (e.g., bullets and warheads). The purpose of ammunition is to project a force against a selected target to have an effect (usually, but not always, lethal). An example of ammunition is the firearm cartridge, which includes all components required to deliver the weapon effect in a single package. Until the 20th century, black powder was the most common propellant used but has now been replaced in nearly all cases by modern compounds. Ammunition comes in a great range of sizes and types and is often designed to work only in specific weapons systems. However, there are internationally recognized standards for certain ammunition types (e.g., 5.56×45mm NATO) that enable their use across different weapon ...

Hydroelectricity
Hydroelectricity, or hydroelectric power, is Electricity generation, electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other Renewable energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Lowell, Massachusetts
Lowell () is a city in Massachusetts, in the United States. Alongside Cambridge, It is one of two traditional seats of Middlesex County.

Oriental Powder Company
Oriental Powder Company was a gunpowder manufacturer with mills located on the Presumpscot River in Gorham and Windham, Maine. The company was one of the four largest suppliers to Union forces through the American Civil War. History The Presumpscot River dropped 16 feet at Gambo Falls where the river formed the border between the towns of Windham and Gorham. Sebago Lake formed a large natural reservoir upstream of Gambo giving the falls an unusually reliable water supply with comparatively minor flow peaking from storm runoff.Wells, Walter ''The water-power of Maine'' (1869) Sprague, Owen & Nash, Augusta Early European settlers built a sawmill powered by the falls. In 1824 the sawmill was converted to a powder mill by Edmund Fowler and Lester Laflin. Their Gorham Powder Company became known among the local population as the Gambo powder mills. Lester Laflin was a grandson of American Revolutionary War gunpowder manufacturer Matthew Laflin. The Laflin family manufactured gunpowd ...

Miami Powder Company
Miami Powder Company operated a gunpowder manufacturing complex on the Little Miami River at Goes Station, Ohio from 1855 to 1925. Willows growing along the banks of the Little Miami River provided the charcoal required for gunpowder. Production was approximately 75 percent rifle powder and 25 percent blasting powder. History Brothers by the name of Chapman built a mill pond dam on the Little Miami River about 1825 to power a mill manufacturing scythes. About 1846 Benjamin Carlton and the Austin brothers of the Austin Powder Company formed the Austin & Carlton Powder Company to convert the mill to the manufacture of gunpowder. Joseph W. King purchased the Austin & Carleton powder mill in 1855 and expanded it as the Miami Powder Company including a steam power plant and employee residences for the company town of Goes Station. In 1872 Miami Powder Company formed the United States Gunpowder Trade Association, popularly known as the powder trust, with American Powder Mills, Austin P ...
