Proprietors Of Locks And Canals
The Proprietors of Locks and Canals on Merrimack River is a limited liability corporation founded on June 27, 1792, making it one of the oldest corporations in the United States. Its named incorporators were Dudley Atkins Tyng, William Coombs, Joseph Tyler, Nicholas Johnson, and Joshua Carter. The company was founded to construct the Pawtucket Canal around the Pawtucket Falls on the Merrimack River, in East Chelmsford, Massachusetts. Over a mile long with four lock chambers, the Pawtucket Canal was finished in 1796. Although the canal allowed for lumber and other goods to be transmitted from New Hampshire to the shipyards of Newburyport, the competing Middlesex Canal, a direct route to Boston, opened just ten years later, ruining the Pawtucket's business. In 1821, The Boston Manufacturing Company of Waltham, Massachusetts, purchased the charter of the Proprietors of Locks and Canals, incorporating it into the new Merrimack Manufacturing Company. In the early 1820s, the Pawtucke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limited Liability Corporation
A limited liability company (LLC for short) is the US-specific form of a private limited company. It is a business structure that can combine the pass-through taxation of a partnership or sole proprietorship with the limited liability of a corporation. An LLC is not a corporation under state law; it is a legal form of a company that provides limited liability to its owners in many jurisdictions. LLCs are well known for the flexibility that they provide to business owners; depending on the situation, an LLC may elect to use corporate tax rules instead of being treated as a partnership, and, under certain circumstances, LLCs may be organized as not-for-profit. In certain U.S. states (for example, Texas), businesses that provide professional services requiring a state professional license, such as legal or medical services, may not be allowed to form an LLC but may be required to form a similar entity called a professional limited liability company (PLLC). An LLC is a hybrid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patrick Tracy Jackson
Patrick Tracy Jackson (August 14, 1780 – September 12, 1847) was an American manufacturer, one of the founders of the Boston Manufacturing Company of Waltham, Massachusetts, and later a founder of the Merrimack Manufacturing Company, whose developments formed the nucleus of Lowell, Massachusetts. Early life and education He was born in Newburyport, Massachusetts, the youngest son of Jonathan Jackson and his second wife, Hannah Tracy Jackson, who was the daughter of Irish-born merchant Patrick Tracy. He enjoyed more schooling than most young men in post-Revolutionary America, attending Newburyport public schools as well as the private Dummer Academy. Growing up in a commercial family, however, Jackson was anxious to prove his business acumen, so in 1795, at the age of fifteen, he served as an apprentice clerk to William Bartlett, a wealthy Newburyport merchant, and as captain's clerk to his elder brother Henry. He spent several years at sea on behalf of Bartlett and his bro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canals In Lowell, Massachusetts
Canals or artificial waterways are waterways or engineered channels built for drainage management (e.g. flood control and irrigation) or for conveyancing water transport vehicles (e.g. water taxi). They carry free, calm surface flow under atmospheric pressure, and can be thought of as artificial rivers. In most cases, a canal has a series of dams and locks that create reservoirs of low speed current flow. These reservoirs are referred to as ''slack water levels'', often just called ''levels''. A canal can be called a ''navigation canal'' when it parallels a natural river and shares part of the latter's discharges and drainage basin, and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley. A canal can cut across a drainage divide atop a ridge, generally requiring an external water source above the highest elevation. The best-known example of such a canal is the Panama Canal. Man ...

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.

Wood Preservation
Wood easily degrades without sufficient preservation. Apart from structural wood preservation measures, there are a number of different chemical preservatives and processes (also known as "timber treatment", "lumber treatment" or "pressure treatment") that can extend the life of wood, timber, and their associated products, including engineered wood. These generally increase the durability and resistance from being destroyed by insects or fungi. History As proposed by Richardson, treatment of wood has been practiced for almost as long as the use of wood itself. There are records of wood preservation reaching back to ancient Greece during Alexander the Great's rule, where bridge wood was soaked in olive oil. The Romans protected their ship hulls by brushing the wood with tar. During the Industrial Revolution, wood preservation became a cornerstone of the wood processing industry. Inventors and scientists such as Bethell, Boucherie, Burnett and Kyan made historic developments in wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Washington Whistler
George Washington Whistler (May 19, 1800 – April 7, 1849) was a prominent American civil engineer best known for building steam locomotives and railroads. He is credited with introducing the steam whistle to American locomotives. In 1842, Tsar Nicholas I hired him to build the Saint Petersburg–Moscow Railway, Russia's first large-scale railroad.Gasparini, D. A., K. Nizamiev, and C. Tardini. "GW Whistler and the Howe Bridges on the Nikolaev Railway, 1842–1851", American Society of Civil Engineers, ''Journal of Performance of Constructed Facilities'' 30.3 (2015): DOI link:04015046.https://dx.doi.org/10.1061/(ASCE)CF.1943-5509.0000791 One of Whistler's important influences was the introduction of the Howe truss for the Russian railroad's bridges. This inspired the renowned Russian engineer Dmitrii Ivanovich Zhuravskii (1821–1891) to perform studies and develop structural analysis techniques for Howe truss bridges. He was the father of American artist James McNeill Whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Francis Turbine
The Francis turbine is a type of water turbine. It is an inward-flow reaction turbine that combines radial and axial flow concepts. Francis turbines are the most common water turbine in use today, and can achieve over 95% efficiency. The process of arriving at the modern Francis runner design took from 1848 to approximately 1920. It became known as the Francis turbine around 1920, being named after British-American engineer James B. Francis who in 1848 created a new turbine design. Francis turbines are primarily used for producing electricity. The power output of the electric generators generally ranges from just a few kilowatts up to 1000 MW, though mini-hydro installations may be lower. The best performance is seen when the head height is between . Penstock diameters are between . The speeds of different turbine units range from 70 to 1000 rpm. A wicket gate around the outside of the turbine's rotating runner controls the rate of water flow through the turbine for d ...

Paul Moody (inventor)
Paul Moody (May 23, 1779 – July 5, 1831) was a U.S. textile machinery inventor born in Byfield, Massachusetts (Town of Newbury). He is often credited with developing and perfecting the first power loom in America, which launched the first successful integrated cotton mill at Waltham, Massachusetts in 1814, under the leadership of Francis Cabot Lowell and his associates. Early life Paul Moody was born May 24, 1779 at Byfield, Massachusetts, the son of Paul Moody and one of nine children. Although Moody's academic education was limited, at age sixteen he learned the weaver's craft, and soon became an expert. He later went to work at a nail factory of Jacob Perkins, first in Byfield and later in Amesbury, Massachusetts when the company moved. In 1812 he worked for Kendrick and Worthen, makers of carding machinery. On July 13, 1800 (one source says September 1798), he married Susan Morrill of Amesbury. The couple went on to have three sons. Soon after his marriage, he partnered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
