Title: Production adjustment to logarithmic variable resistor - uses section of resistive base cut out to bring device to required value
Inventor: BRETSCHER HELMUT W DIPL ING
IPC: H01C17/235
Filed: 1980-04-05
Abstract: The method is used for adjusting the overall value of a slide variable resistor, especially one with a logarithmic characteristic, so that its characteristic curve is as required after any e.g. hardening processes the resistive material might be subjected to. The resistive material (5) is a slice with a supply connection (2) at one end and a shunt electrode along it (3) which connects with a conducting rail (4) by using a slide. The value of the resistive material and its geometry is selected so that after the burning in time and temperature produce a resistive slice (5) with an entry or low value resistance which is lower than that finally required. To increase the value of a laser source is used to cut (7,8) the resistive material so that pieces may be removed (9) to increase the initial value between input electrode (2) and slide shunt electrode (3). The cut sections are completely removed and the cut conforms to the requirements of the resistors characteristic curve.

Title: Bio-gas generation from household refuse and clarifying sludge - by mixing and grinding, swelling, flotation, water-extn., anaerobic putrefaction and composting
Inventor: KNEER FRANZ XAVER
IPC: C02F11/12
Filed: 1980-04-21
Abstract: Bio-gas generation comprises comminuting and mixing untreated household refuse with non-dehydrated clarifying sludge by a 2- or multi-step grinding process, pref using a 2- or multi- compartment ball mill. The sludge obtd is swelled for several hrs. All sludge components incapable of rotting, including plastics, are sepd by one or more flotation processes. The solids content of the remaining sludge is increased to 40% by mechanical water-extn. The dehydrated sludge mixt is made to undergo a controlled anaerobic putrefaction at 30-35 deg C. Anaerobic putrefaction is broken off on reaching max combustible bio-gas yield. A controlled aerobic composting process is then applied to increase hygiene and form humus. The heat required for anaerobic putrefaction is abstracted from the composting process. The compost can be used as soil-improver. The sludge can be used without processing and the refuse requires no preliminary sorting.

Title: Circuit device for brake lights
Inventor: GESSEL JUERGEN
IPC: B60Q1/44
Filed: 1981-01-02
Abstract: The invention relates to a circuit device for brake lights of vehicles in particular for supplementary brake lights. It consists of a pendulum-like switching element (5) which, given a specific deceleration of the vehicle (23), swivels out of a position of rest and actuates a switching contact (9) of a switch. By means of the switch (4), a circuit (24) for the brake lights or supplementary brake lights is closed. The switching element (5) can be swivelled about a bearing pin (16) in the direction of travel. The swivel angle ( alpha ) of the switching element (5) is bounded by a stop. The switching element (5) is constructed in such a way that it is only actuated by centrifugal force and actuates the switch (4) in the event of a very hard braking of the vehicle (23). During normal travel mode with customary, decelerating braking, the switching element (5) is not actuated because the centrifugal force is too small. <IMAGE>
Patent DE-3108283-A1 (DE)
Title: Guided missile
Inventor: KRANZ WALTER
Filed: 1981-03-05
Abstract: In the case of guided missiles which are provided, for thrust-vector control, with one or more pivoting nozzles which are supported on the guided missile so that they can move in terms of angle, in order to reduce the moment of inertia during a change in the pivoting position and in order to keep the radial pivoting nozzle deflection movements within the missile calibre over a large pivoting range even in the case of thin missiles, each pivoting nozzle is divided into a group, which is equivalent thereto with respect to the thrust-vector control, of identically acting, parallel-connected individual pivoting nozzles, which are supported such that they can pivot individually and are driven jointly in synchronism, having individual thrust performance which is reduced corresponding to the number of nozzles in each group, as a result of which the nozzle dimensions are reduced to such an extent that the moment of inertia of the entire pivoting nozzle group is considerably less than that of the pivoting nozzle replaced by the group, and the free space which is required for the pivoting movements of the nozzle group in the radial direction of the missile is quite considerably reduced. <IMAGE>
Patent DE-3115788-A1 (DE)
Title: Shaft coupling with flexible intermediate ring
IPC: F16D3/76
Filed: 1981-04-18
Abstract: This shaft coupling contains at least one intermediate ring (3) which connects the inner and outer coupling part, is made of flexible material, such as elastomers or the like and is held in a positively locking manner by tooth-like elevations on its inner and outer surface in recesses on the inner and outer coupling part (2 and 1, respectively). Vulcanised into the intermediate ring (3) are spring plates (7) which follow one another in the circumferential direction, lie in radial axial planes and the inner ends of which project beyond the inner cylindrical surface of the intermediate ring (3) and engage in a positively locking manner in recesses (8) in the inner coupling part (2). In order to prevent the elevations from slipping out of the recesses (5) in the outer coupling part (1), there are advantageously vulcanised into the intermediate ring (3), between the spring plates (7) projecting beyond the inner surface, further spring plates (6) which begin at a distance from the inner surface and project by their outer ends into the recesses (5) between adjacent elevations (4) on the outer coupling part (1). In the circumferential direction, the different spring plates (6 and 7) are preferably arranged in an alternating manner. <IMAGE>

Title: Wheel slip control device
Inventor: BERTLING HANNES DR-ING
IPC: B60T8/48
Filed: 1981-05-19
Abstract: A wheel slip control device is proposed which although combined with an antilock device is hydraulically separate from it. A chamber (18, 47) is connected into the brake line (2), which chamber remains unchanged in normal braking but can be adjusted so as to pressurise the brake line (2) should the wheel slip control device respond. This not only prevents the master cylinder top-up reservoir from running empty but also avoids any change in the characteristic curve when braking. The wheel slip control device is used on the drive axle of a motor vehicle, preferably a passenger car. <IMAGE>
