Principal view of the pumping action of a twin-screw pump with a six-lobe female screw and a five-lobe male screw. A compressor (as opposed to a pump) would be shaped the same way, except that the shape of the lobes would change along the length of the screw, so that the volume of the trapped pockets would get squeezed smaller as they get closer to the exhaust port.
In the axial compressor the air flows parallel to the axis of rotation. Axial compressors are made to be multi-staged. A stage consists of a row of rotating blades called the rotor, which are connected to the central shaft and a row of stationary or fixed blades called stator. In axial flow compressor, the air flows from stage to stage.

A cobalt bomb is a type of "salted bomb": a nuclear weapon designed to produce enhanced amounts of radioactive fallout, intended to contaminate a large area with radioactive material, potentially for the purpose of radiological warfare, mutual assured destruction or as doomsday devices.
Riefensthal also "reversed the film to make the divers turn backwards, holding them in the air as if to defy the laws of gravity". [38] Many of these shots were relatively unheard of at the time, but Riefenstahl's use and augmentation of them set a standard, and is the reason they are still used to this day. [ 44 ]
The HVAC system uses an AC induction motor to drive a sealed-system scroll compressor, a design principle not usually used in automotive applications. Using a scroll compressor increases the efficiency of the system while driving it with an AC induction motor makes the system more flexible, so the AC can run while the engine is off. Because the ...
The metal has the unfortunate property of producing a fine dust, causing problems with radiation protection. Cobalt from radiotherapy machines has been a serious hazard when not discarded properly, and one of the worst radiation contamination accidents in North America occurred in 1984, when a discarded radiotherapy unit containing cobalt-60 ...
