Patent DE-2314436-A1 (DE)
Title: Vibration damping system for high yield speed centrifuges - having both electromagnetic and mechanical damping components
Inventor: BOEHRINGER ANDREAS PROF DR ING
IPC: B04B9/12
Filed: 1973-03-23
Abstract: Rotor motion of high speed centrifuges is stabilised by a damping system. There is no mechanical connection between the rotor and its surroundings and the restraining force necessary to maintain the rotor on its rotational axis is provided by means of magnetic forces. The damping system is provided partly or completely by mechanical, hydraulic or hydropneumatic forces acting on the rotor. This damping functions partly or completely through a damping/bearing system mechanically connected to the rotor and which rotates with it but has no mechanical connection to the surroundings. A ring of solid material rotates with the rotor and is connected to it by a series of springs and wires to form flexible connections. This permits motion relative to the rotor and the vibration is damped hydraulically, hydropneumatically or by eddy currents. For use on high speed centrifuges operating at >=1000 revolutions per second above in which the rotor has velocities of 500 m/s or over. The problems with existing systems (a) for effective magnetic damping it is not always possible to keep the physical gap close enough for magnetic forces to be effective (b) the stabilising forces being too low, the damping to poor (c) further variation the stabilising forces occurs if the gap increases due to elastic deformation of the rotor. The system overcomes these problems.

Title: Cyclone dust separator with filter on dust outlet - permits concentration of gas entering filter thus reducing size
Inventor: HAAF AUGUST WILHELM
IPC: B01D50/00
Filed: 1973-06-08
Abstract: A dust separator for gases comprises >=1 cyclones and a filter. The dust extraction pipe from the cyclone(s) is connected to a suction line leading to the filter. Where there is a single cyclone, this dust extraction line leads directly to the filter; where there are several cyclones, the dust extraction pipe leads to the cyclone next downstream and so finally to the filter. Since the clean gas outlets from the cyclones lead directly to the clean gas removal duct without any intermediate filters, the quantity of air required to pass through the filter is considerably reduced and is highly enriched. This enables the size of filter to be reduced appreciably.
