Patent DE-3144883-A1 (DE)
Title: Electrical switch, especially for a central door-locking system in motor vehicles
Inventor: MUTSCHLER ERICH
IPC: E05B77/48
Filed: 1981-11-12
Abstract: The invention is based on an electrical switch, especially for a central door-locking system in motor vehicles. This switch has a contact support on which a plurality of stationary contacts are seated, and a switching element which can move with respect to the contact support and by which at least one contact link can be controlled, by means of which at least two of the stationary contacts can be stressed in a specific direction. In order to be able to produce a left-hand and a right-hand version of such a switch with as many identical parts as possible, it is proposed according to the invention that both the contact support and the switching element be constructed in each case symmetrically with respect to a central plane to which the specific direction is at right angles. The different switch versions can then be obtained just by different fitment of the contact support and of the switching element, and by mirror-image mounting of these parts.

Title: Multi-gear free-wheeling hub for bicycles in a full-floating axle design
Inventor: KELLER JOSEF ING GRAD
IPC: B62M11/16
Filed: 1982-01-30
Abstract: Drive hub (10) with a multi-gear internal hub gear change which can be actuated via axially displaceable pawls (35). In order to transmit the axially directed changing movement, a changing bushing (12) which is arranged, fixed in terms of rotation, in an axial groove (24) but is axially displaceable, is assigned to the latch carrier (11). The changing bushing (12) is connected to a rotatable, but axially fixed threaded bushing (13) via a rising toothed thread (23) to a rotational, but axially fixed thread bushing (13). This rotatable threaded bushing (13) can be rotated concentrically with respect to the hub axis (41) via a tangentially extending changing wire cable (17) by means of a radial changing lever (16) which engages on said threaded bushing (13), as a result of which an actuation of the internal hub gear change is brought about. In the hub axis (41) which is no longer taken up by the changing cable, the continuous tensioning pin (43) of a quick-tensioning device can now be arranged.   <IMAGE>

Title: Device for keeping constant the reduced bearing pressure of a working appliance
Inventor: SCHLIESING HANS
IPC: A01D34/86
Filed: 1982-02-25
Abstract: Working appliances, such as, for example, flail-type mowers, which are articulated on the free end of a jib mounted on a carrier vehicle, are, when in use, to exert a load on the ground with only some of their weight. The invention provides a device by means of which a set reduced bearing pressure of the working appliance on the ground is kept constant even when the working distance from the carrier vehicle varies. There is therefore no need for a separate raising and lowering of the jib during such a change. For this, the pressure-medium cylinder pivoting the jib arm located near the vehicle can be connected selectively to the hydraulic system of the carrier vehicle or to the hydraulic system of the working appliance. A throttle is arranged in its main pressure-medium line, and a pressure-regulating valve is arranged in a pressure-medium feed line branching off to the pressure-medium cylinder in front of the throttle. Further measures ensure that the moment resulting from the force of the pressure-medium cylinder and its effective distance from the point of articulation of the jib arm is proportional to the distance of the working appliance from the carrier vehicle. <IMAGE>

Title: Automatic screwing device for electricity meters
Inventor: HEMMING BERNHARD DIPL ING
IPC: B23P19/06
Filed: 1982-05-04
Abstract: During the testing of electricity meters, it is required to open the connection (calibration tab) existing between the current and voltage paths, which is closed during operation of the meters, and to close it again after the testing. To reduce the not inconsiderable time consumed during the manual screwing-down, a device has been developed in which the electricity meters are pushed onto an inclined plane of about 45 DEG  via a conveyor belt before and after the testing. The screws of the calibration tabs are opened via pneumatic screwdrivers with the aid of a programmed controller. During this process, the calibration tabs, which are constructed as folding or sliding tabs, are shifted by vibrating the meter.

Patent DE-3230726-A1 (DE)
Title: Method for interference-proof short-wave radio transmission
Inventor: HANNI MANFRED
IPC: H04B1/713
Filed: 1982-08-18
Abstract: In short-wave radio transmission, in particular in telex connections, measures must be provided for data security in the form of FEC or ARQ in the case of more stringent requirements in terms of the quality and availability of the transmission path. As in the radio bit rate upwardly limited by short-time fading, a correspondingly lower useful bit rate must be accepted for the sake of data security. A further reduction in the essentially available radio bit rate for the useful information is produced with the additional use of a diversity. To enable transmission which is interference-proof even to specific extraneous interference, it is proposed that, along with data security measures in the form of FEC or ARQ and an "in-band diversity", the frequency of the radio frequency carrier (fr) is additionally modified in pseudo-random fashion in a fast changeover matched to the information block pattern of the information and the reciprocal time shift of the information transmitted simultaneously in the in-band diversity channels is to be selected at least equal to the shift interval of the radio carrier frequency. <IMAGE>

Patent DE-3312885-A1 (DE)
Inventor: BLUMRICH GERALD DIPL ING
IPC: F24C15/34
Filed: 1983-04-11
Abstract: The present systems for heat distribution for heating building rooms in general do not take into account the physiological human needs, respectively are not adapted to the present confort and operation standards and may hardly be integrated in the construction elements which delimit the rooms, since the sizes of those heating elements, respectively their thermal outputs may be varied only insufficiently. The present invention remedies to these various disadvantages by assembling a ceramic wall heating element from isolated modules (1) to a desired size and by integrating the element to the wall of the room to be heated; all isolated modules comprise parallel channels (4) arranged to receive pipes wherein a heat conveying medium circulates. Thereby, a ceramic wall heating element is obtained which enables a heat output in the room essentially in the form of radiating heat.

Patent DE-3319588-A1 (DE)
Title: Method for transmitting signals by means of an alternating current heterodyned from two alternating currents of the same frequency phase shifted by 90 DEG
Inventor: DIRR JOSEF DIPL ING
IPC: H04N11/06
Filed: 1983-05-30
Abstract: The amplitudes of alternating currents are in many cases provided for the coding of information. In this connection, two such alternating coding currents of the same frequency are frequently phase-shifted by 90 DEG  and heterodyned. This produces an alternating heterodyned current with the frequency of the alternating coding currents and their information. When the amplitude of the alternating coding currents changes, a phase shift occurs in the heterodyned alternating current, which has a disadvantageous effect on the band width and on the evaluation. This phase change is reduced or compensated for by the invention in that either a constant is added to each alternating coding current or/and in that the alternating current periods are transmitted more frequently with each phase or quasi-phase change.
