William Stanley Jr.
William Stanley Jr. (November 28, 1858 – May 14, 1916) was an American physicist born in Brooklyn, New York. During his career, he obtained 129 patents covering a variety of electric devices. In 1913, he also patented an all-steel vacuum bottle, and formed the Stanley Bottle Company. Early life and education Stanley was born November 28, 1858, in Brooklyn, New York, the son of William Stanley and Elizabeth A. Parsons Stanley. William Jr. attended Williston Seminary and later graduated from Yale University with the class of 1881. Career Stanley was as an electrician working with tele keys and fire alarms of an early manufacturer. In Philadelphia, Stanley designed one of the first electrical installations (at a Fifth Avenue store). Shortly thereafter, George Westinghouse hired Stanley as his chief engineer at his Pittsburgh factory. In 1885, Stanley built the first practical alternating current transformer based on Lucien Gaulard and John Dixon Gibbs' prototype of 1881. This ...

Electrical Installation
Electrical wiring is an electrical installation of cabling and associated devices such as switches, distribution boards, sockets, and light fittings in a structure. Wiring is subject to safety standards for design and installation. Allowable wire and cable types and sizes are specified according to the circuit operating voltage and electric current capability, with further restrictions on the environmental conditions, such as ambient temperature range, moisture levels, and exposure to sunlight and chemicals. Associated circuit protection, control, and distribution devices within a building's wiring system are subject to voltage, current, and functional specifications. Wiring safety codes vary by locality, country, or region. The International Electrotechnical Commission (IEC) is attempting to harmonise wiring standards among member countries, but significant variations in design and installation requirements still exist.

Morgan Stanley
Morgan Stanley is an American multinational investment bank and financial services company headquartered at 1585 Broadway in Midtown Manhattan, New York City. With offices in 42 countries and more than 80,000 employees, the firm's clients include corporations, governments, institutions, and individuals. Morgan Stanley ranked No. 61 in the 2023 Fortune 500 list of the largest United States corporations by total revenue and in the same year ranked #30 in Forbes Global 2000. The original Morgan Stanley, formed by J.P. Morgan & Co. partners Henry Sturgis Morgan (a grandson of J.P. Morgan), Harold Stanley, and others, came into existence on September 16, 1935, in response to the Glass–Steagall Act, which required the splitting of American commercial and investment banking businesses. In its first year, the company operated with a 24% market share (US$1.1 billion) in public offerings and private placements. The current Morgan Stanley is the result of the merger of the origi ...

Edison 7949430936 A7aee4bddd O
Thomas Alva Edison (February11, 1847October18, 1931) was an American inventor and businessman. He developed many devices in fields such as electric power generation, mass communication, sound recording, and motion pictures. These inventions, which include the phonograph, the motion picture camera, and early versions of the electric light bulb, have had a widespread impact on the modern industrialized world. He was one of the first inventors to apply the principles of organized science and teamwork to the process of invention, working with many researchers and employees. He established the first industrial research laboratory. Edison was raised in the American Midwest. Early in his career he worked as a telegraph operator, which inspired some of his earliest inventions. In 1876, he established his first laboratory facility in Menlo Park, New Jersey, where many of his early inventions were developed. He later established a botanical laboratory in Fort Myers, Florida, in collab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Electric Corporation
General Electric Company (GE) was an American multinational conglomerate founded in 1892, incorporated in the state of New York and headquartered in Boston. Over the years, the company had multiple divisions, including aerospace, energy, healthcare, lighting, locomotives, appliances, and finance. In 2020, GE ranked among the ''Fortune'' 500 as the 33rd largest firm in the United States by gross revenue. In 2023, the company was ranked 64th in the ''Forbes'' Global 2000. In 2011, GE ranked among the Fortune 20 as the 14th most profitable company, but later very severely underperformed the market (by about 75%) as its profitability collapsed. Two employees of GE—Irving Langmuir (1932) and Ivar Giaever (1973)—have been awarded the Nobel Prize. From 1986 until 2013, GE was the owner of the NBC television network through its purchase of its former subsidiary RCA before its acquisition of NBC's parent company NBCUniversal by Comcast in 2011.

Transformer
In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple Electrical network, circuits. A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force, electromotive force (EMF) across any other coils wound around the same core. Electrical energy can be transferred between separate coils without a metallic (conductive) connection between the two circuits. Faraday's law of induction, discovered in 1831, describes the induced voltage effect in any coil due to a changing magnetic flux encircled by the coil. Transformers are used to change Alternating current, AC voltage levels, such transformers being termed step-up or step-down type to increase or decrease voltage level, respectively. Transformers can also be used to provide galvanic isolation between circuits as well as to couple stages of signa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Dixon Gibbs
John Dixon Gibbs (1834–1912) was a British engineer and financier who, together with Lucien Gaulard, is often credited as the co-inventor of the AC step-down transformer. The transformer was first demonstrated in 1883 at London's Royal Aquarium. At the time the term "transformer" had not yet been invented, so instead it was referred to as a "secondary generator". Although he is usually credited equally with Gaulard, Gibb's role in the invention appears to have been more that of a financial backer and businessman. Although the underlying physics of the transformer, mainly Faraday's law of induction, had been known since the 1830s, transformers became viable only after the introduction of Gaulard and Gibbs's transformer design in 1883. The breakthrough was to build an iron transformer core which could act as a magnetic circuit. At the time, their invention was seen as overcomplicated since it contained a movable armature. It caught the attention of Sir Coutts Lindsay, who used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
