Title: Sewing machine fabric advance - has a worm gearing with cam to reduce play
Inventor: GUDER KLAUS
IPC: F16H37/14
Filed: 1979-01-25
Abstract: In the fabric advance mechanism of a sewing machine, using a worm gearing, the worm has a constant pitch, while a keyed cam is mounted with an axial sliding action. A section of the edge of the cam engages in a fixed guide. One part of the edge corresponds with a negative pitch of the worm, while the remainder of the edge gives a positive pitch.

Title: Step-ladder providing compact storage - has pivoting steps which are horizontal in working position but vertical when not in use
Inventor: KUEMMERLIN WALTER
IPC: E06C1/393
Filed: 1980-05-21
Abstract: A step-ladder has a pair of front legs (201) hinged to a pair of rear legs (202). The front legs consist of two main side members (203) with pivots (218) to support the steps (220). The inner ends of the steps are pivoted to a bar (211) which is also connected by a pivot (242) to the rear legs. When the legs are swung apart to their working position the bar brings all the steps to the horizontal position to provide level steps. At the same time the bar increases the rigidity of the side members. When the legs are brought together the bar swings the steps so that they are aligned with the main side members and so need less storage space.

Title: Position location of contact point on data panel - has signals generated by pointer contact detected by electroacoustic converters and evaluated by digital circuit
Inventor: CRINGLE FRANK
IPC: G06F3/043
Filed: 1980-07-23
Abstract: A digital system is used to interpret the output of electro- acoustic detectors to identify the location of a hand held pointer on an X-Y data field. When the pointer is tapped on the surface of the data panel, built in electro acoustic detectors (A,B,C) are existed. The sinusoidal outputs are processed by differentiator stages (7) to indiate the first zero-crossing points. Threshold trigger stages (8) identify a set level and flip-flops (21,23) are set to gate clock pulses into counters (10-12) for a specific period. At the end of the period the counter states identify the co-ordinate location of the entry point.

Title: Wind power generator with turbine and converter - has control unit regulating energy conversion to minium during start=up phase
Inventor: KRAMER PETER DIPL ING
IPC: F03D9/25
Filed: 1980-07-29
Abstract: The wind-operated power generator consists of a wind turbine with rotor blades and an energy converter. The rotational energy of the wind turbine is converted into a suitable form of energy. It does not require any complicated mechanical regulation. The energy converter (4) is controllable. The control unit (7) regulates the conversion of the energy in the energy converter. The control unit keeps the converted energy in the energy converter to a minimum during the start-up phase of the wind turbine (1). The output power of the energy converter can be made proportional to the surge power of the speed of the wind turbine. The output is kept constant at high speeds.
Patent DE-3029485-A1 (DE)
Title: Hydraulic multiway motor control valve independent of load - has load-pressure passage controllable by pressure-compensation valve slide
Inventor: BERNHARDT WOLFGANG
IPC: F15B11/044
Filed: 1980-08-02
Abstract: The hydraulic valve controls a hydraulic motor independently of load, having a pressure-compensation valve upstream of the control valve slide. The compensation valve slide is adjusted dependent on pressure, being subjected to upstream pressure in opposition to its spring, and to downstream pressure in the opposite direction. This keeps the pressure drop across the first throttling positions at the control slide constant independent of the value of a positive load on the motor. Second throttles at the control slide pass the fluid from the motor to the tank. Downstream of the control slide and in the return pipe to the tank is a second pressure-compensation valve, subjected to the pressures upstream and downstream of the second throttles in opposition to a spring, keeping the pressure drop across the second throttles constant under a negative load on the motor. A load pressure passage feeds the pressure in the motor chamber connected to the inlet back to a control pressure union. The load pressure passage (64) is controllable by the slide (17) of the second pressure-compensation valve.
