Title: Magnetic bearing operation with controller and power amplifiers - involves use of electromagnet current positive and negative directional measurements in position assessment of levitated object
Inventor: TRAXLER ALFONS DR
IPC: F16C39/06
Filed: 1989-11-13
Abstract: Two electromagnets (1,1') are energised from separate power amplifiers (3,3') to exert a lifting force on the rotor (4) of a rotating machine positioned between them. The control (5) operates on signals (yip,yin) from current transformers (2,2') in the power lines from the amplifiers (3,3'): to the respective electromagnets (1,1'). The state of movement of the rotor (4) is worked out for  the purpose of stabilising its contactless floating position by reaction on the amplifier inputs. This method renders movement sensors, as such, superfluous and eliminates errors by using data obtd. from the bearing itself and not from sensors making measurements at another location. ADVANTAGE - More compact and less costly structure enables air gap data to be used instead of movement measurements by sensors sepd. from bearing.

Title: Dispenser for delivery of pasty compounds
Inventor: SCHUCKMANN ALFRED VON
IPC: B65D83/00
Filed: 1990-03-01
Abstract: The dispenser comprises a tubular housing (1) and a plug-in cartridge (2) associated with it in an axially displaceable fashion. The section (1') of the cartridge that projects beyond one end of the housing has an actuating surface (4) and the delivery mouthpiece (6). The plunger (9) is moved stepwise in the direction of the mouthpiece upon actuation. The advance of the plunger, which is guided by the plug-in cartridge, is achieved by  displacement of the cartridge against a support plate (10) of the housing, which plate is resettable in the direction of the delivery mouthpiece. The resetting may be achieved by means of a locking connection (80/81) between the plunger and the support plate, the latter being seated on a column (5) that is extensible, the column being constituted by parts that can be telescoped with respect to one another.

Title: Airship with static lift by air compression - has airtight shell, forming hollow, cylindrical composite structure
IPC: B64B1/06
Filed: 1990-03-27
Abstract: An airship is constructed with a hollow cylindrical body, which encloses one or more air-tight compartments constructed to resist an external pressure.
