Title: Pendulum lever drive driven by muscle power
Inventor: JUSTUS OTTO
IPC: B62M1/24
Filed: 1988-02-17
Abstract: By means of sensible use of simple control elements, this invention achieves the object of providing a drive driven by muscle power, which controls a mechanical advantage adaptation in dependence on the load and thus automatically, steplessly and continuously with such a degree of accuracy that even small load changes are immediately corrected. These control characteristics also have an effect in the case of the operation of a plurality of pendulum lever drives, namely as a result of the fact that all of the active pendulum levers are simultaneously controlled by a common load. A not unimportant feature is the possibility of accelerating or slowing down the control operation, so that it deviates from the basic setting, by individual setting of the spring prestress. The simple, compact construction of the pendulum levers and the maintenance-free control elements, which exhibit extremely low wear, are a further positive factor. The pendulum levers are illustrated diagrammatically and also show functional elements which are not the subject of the invention but contribute to a better understanding of the explanation.
Patent DE-3805427-A1 (DE)
Title: Method for reproducing the opening states of roof-ventilation devices
Inventor: MEIER SIEGFRIED DIPL ING
IPC: F24F7/02
Filed: 1988-02-22
Abstract: Method for determining and reproducing the opening states of roof-ventilation devices, such as motor-driven roof domes. After cancellation of all closing commands to all ventilation elements, for example from wind and rain detectors or time switches, old opening states have hitherto not been reproduced. By means of a new measuring and controlling method, the opening states are determined and reproduced without the use of direct measuring devices on the ventilation elements. A microcomputer determines the opening state indirectly from the running times of the drives. The running and running direction of the drives is recognised from the signals to the drives and the current flow to the drives. These are stored and thus permit reproduction of old opening states after cancellation of all closing commands.

Title: Single-pole plug connection
Inventor: MANG HEINO
IPC: F02B3/06
Filed: 1988-09-23
Abstract: The invention relates to a single-pole plug connection having a pin part (2, 3) and having a socket part (1) which has an insulating housing (9, 10) and, arranged in it, a plug socket (8) and a locking spring (21) which engages automatically in a cut-out (7) in the plug pin (2), when the plug connection is mated. This plug connection is intended to be developed in a manner which is as simple and cost-effective as possible such that, in contrast to the prior art, it is suitable for the use of plug pins and plug sockets having, in principle, any desired cross-section, ensures a high current load capacity, even at high temperatures, with the spring force of the locking spring at the same time being of equal magnitude, and is constructed without any parts which move significantly with respect to one another. To this end, it is provided that the locking spring (21) is a separate part, at least one section (23) of which passes through a cut-out (20) in the plug socket (8), projects into the cut-out (7) in the plug pin (2) when the plug connection is locked and has two free limbs (22) which project approximately radially outwards from the plug socket (8) and between which a wedge (26), which is connected to the insulating housing (9), is inserted when the plug connection is being broken, in order to unlock it. An advantageous refinement of the invention comprises, for example, the plug pin (2) forming the cable connecting part of a glow plug (3) for diesel engines. <IMAGE>

Title: Back rest for a weaving machine
Inventor: BOEHM HEINZ-DIETER DR ING
IPC: D03D49/22
Filed: 1988-11-26
Abstract: The endeavour to design the back rest serving for compensating the shed movement with as little mass as possible, in order to prevent the effects of inertia force on the warp threads, is restricted by the constructive requirements for sufficient stability of the back rest. By means of the present invention, it is proposed to design the back rest in two parts and to design the guide face for the warp threads, for example, as the outer face of a top which is articulated elastically movably on a gutter-like basic body and which is pressed against the warp threads by a cavity loaded with gas pressure. As a result of this design, the forces exerted by the warp threads are absorbed by the pressure forces in the cavity. The top part itself can be made light and with low inertia. Use in weaving machines. <IMAGE>
