Title: LF amplifier for car radio - has preamplifier stage to control amplifier distortion factor with limiter controlled by comparator
Inventor: WEISHAUPT WALTER ING GRAD
IPC: H03G1/04
Filed: 1980-08-09
Abstract: The low frequency amplifier circuit includes a facility by which the distortion factor is not substantially charged by amplitude adjustment. The amplifier circuit is suitable for use in road vehicle radio or cassette units. The amplifier has a voltage controlled stereo low frequency preamplifier (1), that processes the right and left stereo channel signals (2,3) and transmits outputs (4,5). The preamplifier is controlled by low and high frequency regulators (6,7) and a balance control (8). The volume control unit (9) is coupled over a volume limiting stage (10) to an input (11) on the amplifier. The limiter is controlled by a comparator (12) coupled to the control voltage stage (13).

Title: Control device activated by pressure medium
Inventor: GOETTLING HELMUT
IPC: F16P3/22
Filed: 1981-05-29
Abstract: The invention relates to a control device which is activated by pressure medium and is used for a double-acting working cylinder, in particular for machine tools. The control device has a first multi-directional valve, via which the chambers of the working cylinder can be connected alternatingly to a pressure medium source.

Patent DE-3138547-A1 (DE)
Inventor: WEYL HELMUT DIPL ING
IPC: G01N27/416
Filed: 1981-09-28
Abstract: It is proposed to embody the heating element of an electrochemical detector probe by means of a resistance with a positive temperature coefficient (PTC) or to connect such a resistance in series with the heating element, the probe being immersed in the medium to be measured. There is thus obtained a drop of the heating output of the heating element of the measuring probe when the temperature of the gas to be measured is high. The damage to the probe by a overheating is then prevented. As a resistance wire, nickel or nickel-iron alloys may be used.

Title: Ignition timing control system for an internal combustion engine
Inventor: SUZUKI MIKIO
IPC: F02P5/155
Filed: 1981-11-03
Abstract: An ignition timing control system for an internal combustion engine is characterised by an ignition device, a power increase sensing device, a control device and a temperature sensing device. The ignition device produces an ignition spark in an engine combustion chamber. The power increase sensing device detects an increase in the output power required by the engine. The control device is connected to the ignition device for controlling the ignition timing and likewise to the power increase sensing device in order to retard the ignition timing in line with the engine crank angle when an increase is required in the output power of the engine. The temperature sensing device senses the temperature of the engine coolant and, in response to the coolant temperature, temporarily reverses the retardation of the ignition timing due to the increase in engine power.

Title: Microwave antenna array
Inventor: BRAEUNER WALTER DIPL ING
IPC: H01Q3/30
Filed: 1982-02-24
Abstract: A teaching is specified for calculating the phase values for each aerial element of the antenna array required to generate a desired antenna directional characteristic, it being assumed that, for given amplitude shading, only the phase shading has to be calculated as the variable. In the past, it was only known for the beam deflection and beam widening to be achieved by phase control of aerial elements. A more wide-reaching beam modification, that is to say beam forming, is made possible for the first time by the invention. The invention can be used, for example, in electronically phase-controlled radar antennas. <IMAGE>

Patent DE-3210823-A1 (DE)
Title: Push button tuner
Inventor: CHAKI TAKAO
IPC: H03J5/12
Filed: 1982-03-24
Abstract: A push button tuner comprises actuation rods (23) which can be moved in the forward and reverse direction of the tuner and at the front ends of which push buttons (24) are mounted. At a central position of each actuation rod, an engagement area (28) is formed which engages a locking element (30) in order to lock the actuation rod in a certain position when the associated push button is pressed in. A tuning mechanism can be operated by the actuation rod locked by the locking element. The push button tuner is distinguished by the fact that at least one locking release device (24C, 33A, 33) is provided in order to release the actuation rods locked by the locking element when the associated push button is pushed in deeper. This prevents these push buttons from no longer being returnable to their starting positions when all push buttons are pushed in due to an operator error. <IMAGE>
Patent DE-3225506-A1 (DE)
Title: Anti-theft device and recovery unit for vehicles
Inventor: TINOCO GUTIERREZ CARLOS
IPC: B60R25/102
Filed: 1982-07-08
Abstract: The invention relates to an anti-theft device and a recovery unit for vehicles, having a radio transmitter which, in the event of unauthorised use, emits a signal received by one or more receivers accommodated stationarily or moveably in vehicles. The reception of such a signal makes it possible to locate a stolen or unauthorisedly used vehicle in the shortest possible time and even in concealment or after a change in the characteristic of a vehicle, for example the numberplates or the colour. In a development, a signal can be transmitted in reverse to the vehicle and, via a receiver and a circuit, stops the ignition of the vehicle in question and therefore the vehicle engine.

Title: Method and device for the continuous packaging of explosive cartridges
Inventor: GREIFFENBERG HERBERT
IPC: B29C48/157
Filed: 1982-11-19
Abstract: The object of the invention is a method for the continuous packaging of explosive cartridges in plastic flexible tubes produced by pneumatic extrusion, which are cut to length by automatic welding and cutting devices. During this process, the air fed to the blowing head for pneumatic extrusion of the plastic flexible tube is sucked away by a slide-in tube which is used for continuous delivery of the explosive cartridges in batches. The plastic flexible tube is cut to length without additional perforation in a single operating cycle by means of a welding and cutting device which moves in the direction of feed and is known per se. The invention facilitates in an advantageous fashion the removal of air from the plastic flexible tube, production of explosive cartridge packaging which is completely sealed without exerting stress on the welding seams, and more economical production.
