Title: Step-down controller for switched-mode power switchgear units
Inventor: LUETTICH ROLF DIPL ING
IPC: H02M3/155
Filed: 1987-03-26
Abstract: To avoid dangerous interference voltage peaks during rapid blocking and connecting-through (reverse-recovery time) of the freewheeling diode (D0) of a switched-mode power supply unit, an additional relieving network comprising a choke (L1), capacitor (C1) and diode (D1) is connected ahead of the usual forward converter (L0, D0, C0, RA). For the required charging of the capacitor (C1) to the initial state, an additional branch comprising a choke (L2) and diode (D2) is also required. The components (D1, C1, L1) cause the freewheeling diode (D0) to be switched slowly to a conducting state and the choke (L1) causes it to be brought into the blocked state with a defined delay. <IMAGE>

Title: Coupling connection for combination vehicles comprising wheelchair and bicycle
Inventor: REICHMANN HELMUT PROF DR
IPC: B62K13/00
Filed: 1987-04-28
Abstract: The invention relates to the connecting mechanism of combination vehicles which comprise a wheelchair and the rear structure of a bicycle arranged in a pushing manner. In order to reduce the constructional complexity, to facilitate the coupling and uncoupling and to improve the stowability of the vehicle parts in the uncoupled state, it is proposed to design the coupling connection in such a manner that when coupling takes place a joint is produced. This can take place in that there are attached to the inside of the main wheel axles of the wheelchair swivelling bearing bushes into which there are inserted, when coupling up, transverse axles which are situated on a transverse support in front of the steering head. At least one of the axles is displaceable in the axial direction. In the case of folding wheelchairs, coupling and uncoupling takes place in the opened-out state via a rotary handle. The disabled person may at the same time remain seated in the wheelchair. If the procedure of opening out the wheelchair is for its part used to produce the connection by connection bushes, which are fixed on the insides in the region of the main wheel axles, being pushed via axle stubs which protrude inwards in a claw-like manner in front of a transverse support mounted in front of the bicycle-side steering head, the constructional complexity is further reduced. Both connections are so practicable that in less than 10 seconds coupling or uncoupling can take place.

Patent DE-3722060-A1 (DE)
Title: Safety valve protective system
Inventor: SCHUBERT WERNER DR MED
IPC: F16K17/24
Filed: 1987-07-03
Abstract: Incidents in pipes are caused mainly by excess pressures. Excess pressures, as well as pressure surges, have an immediate effect on pneumatic cushions by reducing volume. Such pressure-responsive bodies, which form part of valve bodies in protective systems which can be fitted in pipes exposed to pressure surges, permit automatic pressure-surge dependent valve closures as a precautionary safety measure similar to the known electric current fuse. Several forms of safety valve protective systems of this type are shown with further regard to other safety measures against pipe bursts.

Title: Axial piston machine
Inventor: FETTING DIETER DIPL ING
IPC: F01B3/00
Filed: 1987-10-05
Abstract: The axial piston machine has pistons (21) arranged in bores of a rotating cylinder body (18), which pistons are supported by spherical caps (22) on a pressure disc (23), which in turn bears on a reciprocating body (27). The pressure disc (23) has a central bore (24), which touches an articulated body (25), which is arranged rotationally fixed on the drive shaft (14) for the cylinder drum (18). Due to the friction between the articulated body (25) and the bore (24), the pressure disc (23) is set in rotation as a result of sliding friction, so that the relative speed between the spherical caps (22) of the pistons and the pressure disc (23) is reduced or negated. In this way, wear on the surface of the pressure disc (23) is prevented. <IMAGE>

Title: Tank with water-level indicator as device for long-term care of plants
Inventor: BLOCK HUBERT K
IPC: A01G27/02
Filed: 1987-12-12
Abstract: Conventional subatmospheric-pressure tanks lack mainly:     a) good space utilisation;   b) great capacity;   c) flexibility in tank accommodation;   d) flexibility in water-level levellability;   e) a ("short-stroke") tank water-level indicator;   f) combinable manufacture with other types of tank; g) a good - quick - post-fitting facility in large containers which are already planted; h) a functionally reliable filling technique without movable or compressing elements.   This innovation achieves the aim by means of a compact and/or folding subatmospheric-pressure tank (made: blowing process) which works in a similar manner to the siphon principle, the compact tank, as e.g. a cork-granulate (14a) coated tall tank (3) corresponding on the bottom side to the shape of a cultivation pot (rapid exchange and introduction into existing installations). As tank-content indicator, use is made of a flat, limitedly flexible, longitudinally curved, strip-shaped bar (12b rolled bar dimension) which at one end ends on the weighted float (12a) and the other side (12m) of which, after completion of the actual visible semi-circle (12g), is rigidly locked (12j/k). Alternately, in each case on suspension of the subatmospheric pressure in the tank (3), the respective water level (17a) which is present in the tank (3) is indicated (17b; 12c/d/m) in the externally arranged indicator (12). After the respective introduction of the subatmospheric pressure in the tank (3), the indicating visible strip arch (12g) indicates the water level in the large container (1). <IMAGE>
