摘要： A back-to-back impeller for a radial turbo machine having a first and a second low pressure end (2, 2ʹ) and one high pressure end, which impeller in operation transfers two opposed axial low pressure flows of fluid to one radial high pressure flow of fluid or vice versa. the impeller comprises a first and a second set of impeller blades on a hub, symmetric relative to the impeller axis. These blades define a first and a second set of channels respectively communicating between said first low pressure end (2) and the high pressure end and said second low pressure end (2ʹ) and the high pressure end, respectively. Said blades (4, 4ʹ) are gradually thickened from the low pressure end towards the high pressure end and each channel of said first set of channels is at the periphery portion of the impeller embedded in a blade (4ʹ) of said second set of blades and vice versa. In this way a common high pressure end (5) is formed having all the channel openings in one file around the impeller periphery.

摘要： A fluid pump in which an elastic tube (31) provided with helically extending reinforcing threads (42) acts as pump. The pumping is accomplished by moving one end (32) of tube (31) by means of pressure changes in another elastic tube (21) connected with tube (31).

摘要： A method and a device for controlling a brushless alter-Hating current motor (23) driven by an inverter (31-36) connected to a direct current supply (24,25). The direct current supplied to the inverter is sensed. The signal is passed through a peak detector (41) to a regulator (45), which decreases its frequency controlling output signal if the peak value input signal exceeds a predetermined value. A control signal corresponding to the torque demand of the motor is also produced. This signal controls the voltage supplied to the motor. Negative pulses at the turning off of the inverter switches are also sensed and used for controlling the degree of magnetization of the motor.

摘要： A method of producing large objects from rapidly quenched non-equilibrium powders in which the powder is first slowly precompacted to a predetermined density without causing any substantial temperature rise. The powder is then rapidly compacted by a shock wave having a short rise time In this way thin surface regions on the particles are rapidly brought to melting to cause interwelding of the particles. These thin surface regions are then rapidly quenched by conduction of heat to the interior of the particles. Because of the very rapid heating and quenching, in the order of a few microseconds, degradation of the material is avoided.

摘要： A rotary vane machine having vanes with a three component wear resistant material. The matrix is a fluorocarbon polymer, e.g. PTFE. Furthermore, there are hard phases whose hardness deviates less than 20%from that of the counterface. Glass or carbon is preferable against steel orcast iron. Furthermore an inorganic solid lubricant has been added to the wear resistant material. Lead and lead oxides are particularly good.
