Title: Combined door locking linkage - has central locking and emergency opening lever and parallel guides for locking elements
Inventor: GEYER WOLFGANG E
IPC: E05C9/02
Filed: 1973-09-24
Abstract: The arrangement is intended for doors with a certain degree of air tightness in closed position. This assumes a certain number of locking handles located in different heights on the door leaf and/or frame. Apart from the time consuming operation to attend to the different handles individually, some of them might be located in such a position which is awkward to reach. The present arrangement envisages a single manual handle to operate which automatically moves all locking levers at the same time. The design allows mounting within the double skin of a door so that only the manual handle is visible. Each individual locking lever is adjustable in respect of travel and amount of tightening force.

Title: Emergency wheel inside pneumatic tyre compriises radial plates - with buffer strips forming closed ring to prevent collapse
Inventor: TIEMANN REINHARD DIPL ING
IPC: B60C17/06
Filed: 1974-02-11
Abstract: An emergency running wheel for incorporation inside a pneumatic tyre, to take the load if a puncture should occur, is of smaller external radius to avoid transmission of the load during normal running and consists of a large number of normally radial plates (in planes parallel to the axis of rotation) which can accept load and also pivot out of their radial position under load. The free ends of these plates have thickened-out, compressible bars or strips which are all in successive contact with one another to form a virtually closed, compressible ring inside the tyre. These thickened zones are pref. of natural or synthetic rubber, plastics, or similar matls. They may be circumferentially prestressed, or interlinked. Alternatively there are compressible strips between the plates. The ability to carry load does not depend upon friction of the plate edges where they bear against the inner face of the tyre.

Title: Piston rod guide and seal - has radiused wall of sealing ring groove giving line contact with rod
Inventor: GRUENERT WOLFGANG
IPC: B60T8/18
Filed: 1974-10-03
Abstract: The guide is for use where the piston diameter is large in relation to the guide length of the rod, being particularly for compressed-air brake control units on rail vehicles. The rod passes through a guide portion with an annular groove accommodating a sealing ring. The wall (14) of the grooves (8) nearest the piston forms with the rod (6) a first annular gap (16). The wall (15) furthest from the piston is radiused (18) on the inside. Thus even when the piston is tilted this latter wall gives a virtual line contact with the rod, leaving an annular gap (19) which is very narrow compared with the first one (16).

Patent DE-2536203-A1 (DE)
Title: Rolling mill with hydraulic thickness control - load reducing piston speed acceleration is controlled by feed back system
Inventor: ICHIRYU KEN
IPC: B21B37/62
Filed: 1975-08-13
Abstract: The control maintains constant the thickness of the rolled material. It contains a first amplifier (20) to amplify an input signal by a certain factor (Ka) the input signal being the resultant signal of the negative return of the amount of displacement of a load reducing piston, to the sum of an external reference vlue, and a value, representing the rolling pressure. A phase lead element (21) leads a pre-dettermined phase after an input value has been issued, which is determined by the return of the speed reference, or the sum of speed and acceleration of the load reducing piston, to the output signal of the first amplifier. The output signal of the phase lead element operates a servo valve (22) so that the actual position of the piston may be converged with the rated value, given by the guide reference due to the hydraulically actuated load reducing piston being controlled.

Patent DE-2554191-A1 (DE)
Title: Impulse synchronised motor circuit - uses rotor pulses in combination with control pulses to set applied voltage
Inventor: MAIDA OSAMU
IPC: H02P7/291
Filed: 1975-12-02
Abstract: The dc motor has an impulse generator, typically a switch on its rotor which, in combination with a shaping circuit provides impulses to one input of a bistable switch. The other input is a similar pulse train from a controller. The pulses combine to form an output train whose pulse duration depends on the relative displacement of the two inputs. This output controls the mark-space ratio of the voltage setting circuit (3) and therefore the mean applied voltage of the motor thus controlling the speed. The application is typically to camera or projector drives where the motor speeds has to be synchronised with that of another camera or with external channels such as sound.
