Jerome H. Lemelson
Jerome "Jerry" Hal Lemelson (July 18, 1923 – October 1, 1997) was an American engineer, inventor, and patent holder. Several of his inventions relate to warehouses, industrial robots, cordless telephones, fax machines, videocassette recorders, camcorders, and the magnetic tape drive. Lemelson's 605 patents made him one of the most prolific inventors in American history. Lemelson was an advocate for the rights of independent inventors; he served on a federal advisory committee on patent issues from 1976 to 1979. A series of patent litigations and subsequent licensing negotiations made him a controversial figure, seen as staunch supporter for the rights of independent inventors, while criticized by patent attorneys and directors of some of the companies with whom he was involved in litigation. In 1993, Lemelson and his family established the Lemelson Foundation, a philanthropy with the mission to support invention and innovation to improve lives in the United States and ...

They come in four main pairs of shapes, as given in the box to the right, which also gives their names, that vary between British English, British and American English. "Brackets", without further qualification, are in British English the ... marks and in American English the ... marks. Other symbols are repurposed as brackets in specialist contexts, such as International Phonetic Alphabet#Brackets and transcription delimiters, those used by linguists. Brackets are typically deployed in symmetric pairs, and an individual bracket may be identified as a "left" or "right" bracket or, alternatively, an "opening bracket" or "closing bracket", respectively, depending on the Writing system#Directionality, directionality of the context. In casual writing and in technical fields such as computing or linguistic analysis of grammar, brackets ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pulse Jet
file:Pulse Jet Engine.PNG, 300px, Diagram of a valved pulsejet. 1 - Air enters through valve and is mixed with fuel. 2 - The mixture is ignited, expands, closes the valve and exits through the tailpipe, creating thrust.3 - Low pressure in the engine opens the valve and draws in air. A pulsejet engine (or pulse jet) is a type of jet engine in which combustion occurs in Pulse (physics), pulses. A pulsejet engine can be made with few or no moving parts, and is capable of running statically (that is, it does not need to have air forced into its inlet, typically by forward motion). The best known example is the Argus As 014, Argus As 109-014 used to propel Nazi Germany's V-1 flying bomb. Pulsejet engines are a lightweight form of jet propulsion, but usually have a poor compression ratio, and hence give a low specific impulse. The two main types of pulsejet engines use resonant combustion and harness the combustion products to form a pulsating exhaust jet that intermittently produces ...

Project SQUID
Project SQUID was a United States defense effort post-World War II effort to develop and improve pulsejet and rocket engines, run by the Office of Naval Researchbr> It was started by discovery of the German Argus As 014 pulsejet used on the V1 buzzbomb, which was reverse-engineered as the Republic Ford JB-2, the first American cruise missile. It produced extensive research in the areas of computational flow dynamic and was used to improve the design of the experimental Fairchild XH-26 Jet Jeep, XH-26 Jeep Jet, which used pulsejets on the rotor tips instead of a central engine. The research led to development of pulse detonation engines, which have been suggested as the engines powering the postulated Aurora An aurora ( aurorae or auroras), also commonly known as the northern lights (aurora borealis) or southern lights (aurora australis), is a natural light display in Earth's sky, predominantly observed in high-latitude regions (around the Arc ... spyplane. {{reflist E ...

Aeronautical Engineering
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It has two major and overlapping branches: aeronautical engineering and astronautical engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering. "Aeronautical engineering" was the original term for the field. As flight technology advanced to include vehicles operating in outer space, the broader term "aerospace engineering" has come into use. Aerospace engineering, particularly the astronautics branch, is often colloquially referred to as "rocket science". Overview Flight vehicles are subjected to demanding conditions such as those caused by changes in atmospheric pressure and temperature, with structural loads applied upon vehicle components. Consequently, they are usually the products of various technological and engineering disciplines including aerodynamics, air propulsion, avionics, materials science, st ...

United States Army Air Corps
The United States Army Air Corps (USAAC) was the aerial warfare service component of the United States Army between 1926 and 1941. After World War I, as early aviation became an increasingly important part of modern warfare, a philosophical rift developed between more traditional ground-based army personnel and those who felt that aircraft were being underutilized and that air operations were being stifled for political reasons unrelated to their effectiveness. The USAAC was renamed from the earlier United States Army Air Service on 2 July 1926, and was part of the larger United States Army. The Air Corps became the United States Army Air Forces (USAAF) on 20 June 1941, giving it greater autonomy from the Army's middle-level command structure. During World War II, although not an administrative echelon, the Air Corps (AC) remained as one of the combat arms of the Army until 1947, when it was legally abolished by legislation establishing the United States Department of the Air Fo ...
