Thomas Davenport (inventor)
Thomas Davenport (July 9, 1802 – July 6, 1851) was a Vermont blacksmith who, with his wife Emily, constructed the first American Direct current, DC electric motor in 1834. Biography Davenport was born in Williamstown, Vermont. He lived in Forest Dale, a village in the town of Brandon, Vermont, Brandon. As early as 1834, he and his wife Emily Davenport developed a battery-powered electric motor. They used it to operate a small model car on a short section of track, paving the way for the later electrification of streetcars. It is the first attempt to apply electrification to locomotion. Davenport's 1833 visit to the Penfield and Taft iron works at Crown Point, New York, where an electromagnet was operating, based on the design of Joseph Henry, was an impetus for his electromagnetic undertakings. Davenport bought an electromagnet from the Crown Point factory and took it apart to see how it worked. Then he forged a better iron core and redid the wiring, using silk from his wif ...

Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an sufficiency of disclosure, enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private la ...

People Associated With Electricity
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

19th-century American Inventors
The 19th century began on 1 January 1801 (represented by the Roman numerals MDCCCI), and ended on 31 December 1900 (MCM). It was the 9th century of the 2nd millennium. It was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanded beyond its British homeland for the first time during the 19th century, particularly remaking the economies and societies of the Low Countries, France, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Catholic Church, in response to the growing influence and power of modernism, secularism and materialism, formed the First Vatican Council in the late 19th century to deal with such problems and confirm ce ...

Charles Grafton Page
Charles Grafton Page (January 25, 1812 – May 5, 1868) was an American electrical experimenter and inventor, physician, patent examiner, patent advocate, and professor of chemistry. Like his more famous contemporaries Michael Faraday and Joseph Henry, Page began his career as an astute natural philosopher who developed innovative work with natural phenomena through direct observation and experimenting. Toward the later part of their careers, the science of the day had moved on to a more mathematical emphasis in which these scientists did not participate. Through his exploratory experiments and distinctive inventions, Page developed a deep understanding of electromagnetism. He applied this understanding in the service of the US Patent Office, in support of other inventors, and in pursuing his own ill-fated dream of electromagnetic locomotion. His work had a lasting impact on telegraphy and in the practice and politics of patenting scientific innovation, challenging the rising scie ...

The Electro-Magnetic And Mechanics Intelligencer
''The'' is a grammatical article in English, denoting nouns that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pronoun ''thee'' ...

Joseph Henry
Joseph Henry (December 17, 1797– May 13, 1878) was an American physicist and inventor who served as the first secretary of the Smithsonian Institution. He was the secretary for the National Institute for the Promotion of Science, a precursor of the Smithsonian Institution. He also served as president of the National Academy of Sciences from 1868 to 1878. While building electromagnets, Henry discovered the electromagnetism, electromagnetic phenomenon of self-inductance. He also discovered mutual inductance independently of Michael Faraday, though Faraday was the first to make the discovery and publish his results. Henry developed the electromagnet into a practical device. He invented a precursor to the electric doorbell (specifically a bell that could be rung at a distance via an electric wire, 1831) and electric relay (1835). His work on the electromagnetic relay was the basis of the practical electrical telegraph, invented separately by Samuel Morse, Samuel F. B. Morse and Ch ...
