Tiefschwarz

Tiefschwarz is a tech house group comprising brothers, Alexander "Ali" (June 7, 1967-) and Sebastian "Basti" (December 28, 1969-) Schwarz, which formed in Stuttgart in 1996. Peter Hoff, who runs the Benztown studios in Stuttgart, joined later, and completed the first Tiefschwarz production team. Their name means "deep black" in German, and is a combination of the brothers' surnames, and their love of deep house.

Their earliest productions were released on the Continuemusics label in 1997, and their first taste of a well-respected label was with their Music track on François Kevorkian's Wave Music label in 1999. The team released their first album, RAL9005 on the Four Music label in 2001, which was later licensed to Derrick Carter and Luke Solomon's Classic Recordings label. Tiefschwarz continued to release on Classic until its collapse in 2005, as well as releasing on labels such as Fine and International DeeJay Gigolo Records. Many of their tracks have been licensed to compilations, from the Stereo Sushi series, to compilations for Bugged Out!, Get Physical and Renaissance, and in 2006, they released a mix of their own for the Fabric (London) mix series.

Pistonless rotary engine

A pistonless rotary engine is an internal combustion engine that does not use pistons in the way a reciprocating engine does, but instead uses one or more rotors, sometimes called rotary pistons. An example of a pistonless rotary engine is the Wankel engine.

The term rotary combustion engine has been suggested as an alternative name for these engines to distinguish them from early (generally up to the early 1920s) aircraft engines and motorcycle engines also known as rotary engines. However, both continue to be called rotary engines and only the context determines which type is meant.

Pistonless rotary engines

The basic concept of a (pistonless) rotary engine avoids the reciprocating motion of the piston with its inherent vibration and rotational-speed-related mechanical stress. As of 2006 the Wankel engine is the only successful pistonless rotary engine, but many similar concepts have been proposed and are under various stages of development. Examples of rotary engines include:

Turbine

A turbine (from the Latin turbo, a vortex, related to the Greek τύρβη, tyrbē, meaning "turbulence"), is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Early turbine examples are windmills and waterwheels.

Gas, steam, and water turbines have a casing around the blades that contains and controls the working fluid. Credit for invention of the steam turbine is given both to the British engineer Sir Charles Parsons (1854–1931), for invention of the reaction turbine and to Swedish engineer Gustaf de Laval (1845–1913), for invention of the impulse turbine. Modern steam turbines frequently employ both reaction and impulse in the same unit, typically varying the degree of reaction and impulse from the blade root to its periphery.
