Title: Testing inductive direct voltage loads in domestic equipment - by varying control voltage and evaluating load voltage change using microcomputer
Inventor: SIFFRIN EUGEN ING GRAD
IPC: G01R31/72
Filed: 1980-02-28
Abstract: The method is for testing and monitoring inductive direct voltage loads for functioning and operating condition and is esp. applicable to domestic equipment switched by program control devices via amplifiers, pref. inverters. It enables the associated switching and control elements and cabling to be tested as well as the operating equipment. The control voltage which determines the operating mode, and which is applied to the load, is transiently passed by or cut off by the switching inverters (3,4). The resulting pulse shaped load voltage change, which is caused by the bad power variation associated with the switching process, is measured for height and, where required, for pulse duration. The transient control voltage variation is performed by an electronic control unit, e.g. a microcomputer. The signal voltage change is evaluated in the same unit.

Patent DE-3105944-A1 (DE)
Title: Positive-displacement machine for compressible media
Inventor: EMMENTHAL KLAUS-DIETER
IPC: F01C1/02
Filed: 1981-02-18
Abstract: The invention relates to a positive-displacement machine for compressible media, having at least one spiral-shaped impeller chamber arranged in a slot-like manner in a fixed casing and having a strip-like or tongue-like impeller (displacer), which is likewise fashioned in the manner of a spiral and is retained in each impeller chamber, eccentrically drivable in such a way that each of its points carries out a circular motion delimited by the peripheral walls of the impeller chamber. The curvature of the impeller is to be defined in such a way, compared to that of the impeller chamber, that the impeller nearly touches the inner and outer peripheral walls of the impeller chamber at at least one sealing line, which continuously advances as the impeller is driven. In order to achieve improved sealing between the individual working chambers formed on one side of the impeller, the impeller is to have spaced groove-like or channel-like recesses, which essentially run transversely to the circumferential direction, at its sides facing the peripheral walls of the impeller chamber.
Patent DE-3111121-A1 (DE)
Title: Belt for windsurfers with a releasing mechanism for a rope end of a wishbone boom
Inventor: FRICKE KARL HEINZ
IPC: B63B35/79
Filed: 1981-03-20
Abstract: Belts for windsurfers with a releasing mechanism for a rope end of a wishbone boom are known which have a hook which can be pivoted about a horizontal axis, is open at the bottom and is returned automatically. The pivoting capacity of the hook is limited by a fixed stop and a movable stop, a rip cord acting on the movable stop in order to trigger the releasing mechanism. Hooks of this type do not always function reliably enough, because a dead centre position has to be crossed in order to release them. To remove these disadvantages, the hook is locked in a dead centre position in the initial position, from which it swings over with a snap effect into the released position. This is effected owing to the fact that the hook is made of bar-shaped round material bent roughly at an angle of 90 DEG  and is mounted like a rocking lever on a horizontal pivot at a distance from its top end, that the movable stop essentially consists of a spring which is coiled on a block and is in compression in the non-released state and is in turn mounted at the top end of the hook and on the other side at the housing of the releasing mechanism, and that the releasing mechanism has a pin, bolt or the like which is connected to the rip cord and is mounted in the centre area of the spring in such a way as to be movable transversely to the axis of the spring.

Patent DE-3123105-A1 (DE)
Title: Load interrupter switch
Inventor: LANGMATZ HANS
IPC: H01H9/32
Filed: 1981-06-11
Abstract: The invention is based on a load interrupter switch, especially for cable distribution cabinets, in which no arc is intended to be produced during switching-on or switching-off and which nevertheless dispenses with an automatic interrupter device operating using powerful tension springs, so that it is of relatively small construction. For this purpose, the live metal part (15) of its switching lever (3) is constructed in a U-shape in such a manner that the bevelled lower surface (20) of one limb (18a) is intended to make contact with the input rail (4), and the other limb (18b), which is constructed in like manner, is intended to make contact with the output rail (5). Located in the pivoting zone of the limbs (18a, 18b) are sprung tongues (26) which consist of a plastic which is highly resistant to heat and whose free ends (in the contact position) extend as far as the lower surfaces (20) of the limbs. In the event of switching off by pivoting the switching lever (3), the levers (18a, 18b) also pivot. The free ends of the tongues (26) are then pushed between the surfaces of the rails (4, 5) and the lower surfaces (20) of the limbs and thus prevent an arc being formed. <IMAGE>

Title: Percussion drilling machine
Inventor: BALANDIN VLADIMIR PORFIRIEVIC
IPC: B25D16/00
Filed: 1981-06-23
Abstract: A percussion drilling machine is proposed which contains a housing (1) with a drive and a change-over device for a drilling tool (7), which includes a driving gear (11) with two transmission stages (12 and 13), a bush (14) with a non-circular bore (15) for accommodating a shank (6) of the drilling tool (7), and a safety clutch (A) attached to the bush (14) and meshing with one of the transmission stages (12) of the driving gear (11). Provided in the machine is a driven gear (16) which is attached to the bush (14) in such a way as to be independently rotatable relative to the latter in the housing (1) and meshes with the stage (13) of the driving gear (11). A bore (21) for accommodating a drill chuck (9) is provided in the driven gear (16). The bore (21) has a transverse dimension which exceeds the size of the bore (15) in the bush (14) of the safety clutch. The transmission stage (12) of the driving gear (11) has a smaller number of teeth than the transmission stage (13). This circumstance gives rise to different transmission ratios between the gears (11 and 16) and between the gear (11) and the safety clutch (A), as a result of which it is possible to set optimum rotary speeds of both the drilling tool (7) and the drill chuck (9). <IMAGE>
