Euclid Township, Cuyahoga County, Ohio
Cuyahoga County, Ohio, United States is divided into 21 townships. When Cuyahoga County was founded, it was divided into civil townships for purposes of rural government, as were other Ohio counties. By 1990, this county was the most urbanized county in Ohio, and as a result, most of its townships have been annexed by the city of Cleveland or one of the other municipalities in Cuyahoga County. In Ohio, when the entirety of a civil township has been annexed by one or more municipalities, it ceases to have governmental powers and becomes a paper township, existing on maps, but possessing no governmental powers. Today, 19 of Cuyahoga County's townships are paper townships, with only a part of Olmsted Township and a tiny section of Chagrin Falls Township remaining as civil townships — just of Cuyahoga County's total area of . Bedford Township Although the land that became Bedford Township was bought by the Connecticut Land Company in 1795, no white settlers came until Elijah N ...

Gramme Machine
A Gramme machine, Gramme ring, Gramme magneto, or Gramme dynamo is an electrical generator that produces direct current, named for its Belgian inventor, Zénobe Gramme, and was built as either a dynamo or a magneto. It was the first generator to produce power on a commercial scale for industry. Inspired by a machine invented by Antonio Pacinotti in 1860, Gramme was the developer of a new induced rotor in form of a wire-wrapped ring (Gramme ring) and demonstrated this apparatus to the Academy of Sciences in Paris in 1871. Although popular in 19th century electrical machines, the Gramme winding principle is no longer used since it makes inefficient use of the conductors. The portion of the winding on the interior of the ring cuts no flux and does not contribute to energy conversion in the machine. The winding requires twice the number of turns and twice the number of commutator bars as an equivalent drum-wound armature. Description The Gramme machine used a ring armature, with a se ...

Electrical Generator
In electricity generation, a generator is a device that converts motive power (mechanical energy) or fuel-based power (chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. Generators provide nearly all of the power for electric power grids. In addition to electromechanical designs, photovoltaic and fuel cell powered generators utilize solar power and hydrogen-based fuels, respectively, to generate electrical output. The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors and generators have many similarities. Many motors can be mechanically driven to generate electricity; frequently they make acceptable manual generators. Terminology Electromagnetic ...

American Revolution
The American Revolution was an ideological and political revolution that occurred in British America between 1765 and 1791. The Americans in the Thirteen Colonies formed independent states that defeated the British in the American Revolutionary War (1775–1783), gaining independence from the British Crown and establishing the United States of America as the first nation-state founded on Enlightenment principles of liberal democracy. American colonists objected to being taxed by the Parliament of Great Britain, a body in which they had no direct representation. Before the 1760s, Britain's American colonies had enjoyed a high level of autonomy in their internal affairs, which were locally governed by colonial legislatures. During the 1760s, however, the British Parliament passed a number of acts that were intended to bring the American colonies under more direct rule from the British metropole and increasingly intertwine the economies of the colonies with those of Brit ...

Continental Congress
The Continental Congress was a series of legislative bodies, with some executive function, for thirteen of Britain's colonies in North America, and the newly declared United States just before, during, and after the American Revolutionary War. The term "Continental Congress" most specifically refers to the First and Second Congresses of 1774–1781 and, at the time, was also used to refer to the Congress of the Confederation of 1781–1789, which operated as the first national government of the United States until being replaced under the Constitution of the United States. Thus, the term covers the three congressional bodies of the Thirteen Colonies and the new United States that met between 1774 and 1789. The First Continental Congress was called in 1774 in response to growing tensions between the colonies culminating in the passage of the Intolerable Acts by the British Parliament. It met for about six weeks and sought to repair the fraying relationship between Britain and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
