Paraphrase. A paraphrase or rephrase ( / ˈpærəˌfreɪz /) is the rendering of the same text in different words without losing the meaning of the text itself. [ 1] More often than not, a paraphrased text can convey its meaning better than the original words. In other words, it is a copy of the text in meaning, but which is different from the ...
Free-piston engine used as a gas generator to drive a turbine. A free-piston engine is a linear, 'crankless' internal combustion engine, in which the piston motion is not controlled by a crankshaft but determined by the interaction of forces from the combustion chamber gases, a rebound device (e.g., a piston in a closed cylinder) and a load device (e.g. a gas compressor or a linear alternator).
Compressor. A small stationary high pressure breathing air compressor for filling scuba cylinders. Natural gas compressor at a gas well. High pressure reciprocating compressor from Belliss and Morcom, used in the bottling industry. A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.
Analytical chemistry: Nitrogen generators are required for various forms of analytical chemistry such as liquid chromatography–mass spectrometry and gas chromatography where a stable and continuous supply of nitrogen is necessary. Aircraft & motor vehicle tires: Although air is 78% nitrogen, most aircraft tires are filled with pure nitrogen.
A linear compressor is a gas compressor where the piston moves along a linear track to minimize friction and reduce energy loss during conversion of motion. This technology has been successfully used in cryogenic applications which must be oil-less. The suspension spring can be flexure type or coil type. An oil-free valved linear compressor ...
Micro hydro is a type of hydroelectric power that typically produces from 5 kW to 100 kW of electricity using the natural flow of water. Installations below 5 kW are called pico hydro. [ 1] These installations can provide power to an isolated home or small community, or are sometimes connected to electric power networks, particularly where net ...
