Title: Power-lift control system for motor vehicles
Inventor: TRUMP GERHARD
IPC: A01B63/111
Filed: 1981-07-09
Abstract: The invention serves for supplementing internal types of control, such as position control or pull control in power-lift control systems for motor vehicles, especially farm tractors, by an external control. A connection is made on the transmission elements between the internal pulse generators and the control valve, so that subsequent incorporation is possible in a simple way and the internal controls can be used without disturbance when the external control is not in use. External controls are, for example, the maintenance of the ground clearance of mounted appliances, such as beet lifters or mowing machines, random control as remote operation or the control of the fifth-wheel weight of a mounted appliance by recording the pressure in a working cylinder.

Patent DE-3201885-A1 (DE)
Title: Slidingly guided conveyor belt
Inventor: BRAEUTIGAM JUERGEN ING GRAD
IPC: B65G15/34
Filed: 1982-01-22
Abstract: The slidingly guided feedbelt for wood-sanding machines and the like which are made of rubber or plastic with embedded fabric reinforcements have a tendency to sustain distortions due to their unsymmetrical layer structure which continuously impair their plane-parallel guiding in the work region and questions their very suitability. The invention provides only a single reinforcement layer on the underside of the fabric sliding layer in symmetrical alignment therewith, so that the unavoidable vulcanisation shrinkage balances out and as a result the desired plane-parallel disposition is maintained.

Patent DE-3214665-A1 (DE)
Title: Reflector lighting fixture
IPC: F21V7/04
Filed: 1982-04-21
Abstract: The reflector lighting fixture according to the invention radiates the light energy principally as far as exclusively in the useful range between an upper emission angle and a lower emission angle. By contrast with what is known, in the lighting fixture according to the invention the light energy radiated into the useful range is substantially increased by the component which has previously been directly emitted outside the useful range in what is known. Since the reflector lighting fixture according to the invention radiates no light or only very little in the range below the lower emission angle, troublesome reflections of the lamp body on a glossy visual task are not perceptible. The invention uses a light distribution plate known per se, which has been applied to date in such a way that although it has produced a non-glare range below an angle approximately comparable to the lower emission angle, the guidance of the light in specific privilege directions has been effected exclusively by means of the light distribution plate which has, consequently, also covered the entire light exit opening of the previously known lighting fixture. However, the invention uses the known light distribution plate only partially with a narrow basic form of a long rectangle (in the case of elongated tubular lamps) or with a basic form approximately having the shape of a circular disc with a relatively small diameter (in the case of essentially spherical lamps).

Patent DE-3219445-A1 (DE)
Title: Multi-channel transmission system
Inventor: CERNY JOSEF DR
IPC: H04N7/54
Filed: 1982-05-24
Abstract: A multi-channel transmission system for sound, voice, signalling, acknowledgement and control signals in the form of continuously modulated needle pulses in time-division multiplex, particularly by means of an infrared link. Low-frequency channels with a bandwidth which is wide compared with voice channels are sampled several times at the transmitting end, by means of an analog switch in a modulator (MOD), which analog switch is controlled by a channel shift register (M) via register positions (R) and an OR gate (O1). At the receiving end, a demodulator (DEM) is controlled in the same manner (DM, R, O2). The register positions are selected in such a manner that, assuming a medium modulation deviation in all signal pulses, the individual pulses from the multiple sampling in the entire pulse sequence and in the pulse sequence packet are equidistant in time with respect to one another and mutually in the case of several pulse sequences. This system is used, in particular, for conference systems and central television or broadcast commentator systems with remote commentator stations. <IMAGE>
Patent DE-3220692-A1 (DE)
Title: Portable cooling box
Inventor: ZORN EDGAR
IPC: B65D25/32
Filed: 1982-06-02
Abstract: The portable cooling box has bearing pins which engage through the wall of the cooling box into recesses in the lid and are displaceable axially against an elastic force which results from the deformation of the carrying handle. The pins are cylindrical in shape and have a conical free end which cooperates with a sloping surface on the lid when the latter is pressed into the closed position, so that the pins are pressed outwards against the elastic action of the carrying handle, which is undergoing deformation. In the closed position the pins are pressed by the carrying handle into recesses in the lid. These recesses are cylindrical, so that the lid cannot be opened without pulling out the pins. The pins are pulled out by means of ramps which are arranged on the exterior of the cooling box and with which the carrying handle cooperates within a limited pivoting region, such that the ends of the carrying handle, and thus the pins which are connected to the carrying handle, are pressed outwards.

Title: Closure for the filling opening of a container, for example, for a fruit preparation or the like to be introduced while hot
Inventor: STUMPF FRIEDRICH
IPC: B67C3/22
Filed: 1982-09-04
Abstract: The closure serves for the liquid- and aroma-tight, but detachable closure of the filling opening of a container having been filled with, for example, a fruit preparation to be introduced while hot. Extending through the closure is a flow path in which a shut-off member, for instance a ball valve known per se, which is actuable between a closed position and an open position is arranged. Expediently, this ball valve is fixedly, but detachably associated with the closure, so that instead of a ball valve of this type, it is possible to assign to the lid, for example, a stirring lance which then extends through a closure opening into the container filling.

Patent DE-3300108-A1 (DE)
Title: Electronic anti-theft protection device for motor vehicles
Inventor: FAEHRMANN KURT
IPC: B60R25/045
Filed: 1983-01-04
Abstract: The invention is based on the object of equipping motor vehicles with an anti-theft protection system which prevents, and thus renders impossible, the starting of the engine by unauthorised persons, thanks to this electronic anti-theft protection device: composed of a numerical computer and the associated controllable relay in the engine compartment and a section of connecting cable leading to the number input unit in the region of the driver's seat. The relay opens the circuit if the input numbers correspond to the stored number in the numerical computer and the engine can be started. Short-circuiting at the ignition lock or other tampering with the dashboard area are impossible. The reason is that the electronic controlled relay with the numerical computer is located in the engine compartment in, or downstream of, the distributor. The only possibility open to unauthorised persons would be to attach a jump cable from the distributor to the starter and ignition coil. The numerical computer is preprogrammed with a 5-digit number by the manufacturer, this number is therefore only known to the manufacturer and the owner of the vehicle. The preprogrammed number is entered via the numerical input unit and thus causes the relay to close the interrupted circuit.
