    The EMD SW1500 is a 1,500 hp (1,119 kW) diesel-electric switcher locomotive built by General Motors' Electro-Motive Division from 1966 to 1974. [1] The SW1500 replaced the SW1200 in the EMD product line.

  3. Air-start system - Wikipedia

    en.wikipedia.org/wiki/Air-start_system

    An early axial compressor turbojet had an ATS located in the compressor nose cone (eg particular variants of the J79). Air impingement starting was not used for US military aircraft after the F-4B, A-5A [6] and F-5 as the pneumatic energy requirement was several times greater than when using an air turbine starter. The gas turbine compressor ...

  4. Rotary-screw compressor - Wikipedia

    en.wikipedia.org/wiki/Rotary-screw_compressor

    Consequently, air treatment identical to that used for an oil-flooded screw compressor is frequently required to ensure quality compressed air. In small piston compressors carpenters homeowners sometimes use "oil free" compressors in which oil free is a reference to not using oil but Teflon type of coatings permanently adhered to wear surfaces.

    Included system-oriented layers and troubleshooting, assembly and disassembly aspects. The Advanced Interactive Electronic Technical Manual (A-IETM 1992) was an R&D Augmented Reality (AR) version of this system designed to help to guide the standards used in the mark-up of the documentation - the idea being a UI-independent data stream.

  7. Scroll compressor - Wikipedia

    en.wikipedia.org/wiki/Scroll_compressor

    Animation of a spinning scroll compressor. Léon Creux first patented a scroll compressor in 1905 in France and the US. [2] Creux invented the compressor as a rotary steam engine concept, but the metal casting technology of the period was not sufficiently advanced to construct a working prototype, since a scroll compressor demands very tight tolerances to function effectively.

  9. 1176 Peak Limiter - Wikipedia

    en.wikipedia.org/wiki/1176_Peak_Limiter

    The way the 1176 sounds, and specifically, the way all-button mode sounds, is partially due to its being a program dependent compressor. The attack and release are program dependent, as is the ratio. The 1176 will faithfully compress or limit at the selected ratio for transients, but the ratio will always increase a bit after the transient.
