Title: Infrared remote control for radio and TV receivers - has indicating LED switched off when battery volts drop below min.
Inventor: ROSSTEUTSCHER GERHARD
IPC: H03J9/06
Filed: 1978-10-28
Abstract: The infra-red remote control has the supply voltage for the battery-powered transmitter connected to a monitor that interrupts the current being supplied to the light source (that indicates that the transmitter is functioning) when the supply voltage drops below a given lower limit. The extinguishing of the light source therefore indicates that the battery transmitter needs charging. The monitor is switched on only whilst a function key is operated. The given lower limit to the battery supply voltage is chosen as that voltage at which the power supplied to the infrared diodes is inadequate to permit their radiation to travel the required distance with the required intensity.

Patent DE-2929041-A1 (DE)
Title: Monolithic integrated limiter circuit - employs transistor controlled by voltage divider as voltage sensitive element
Inventor: MUENDEL GERALD DIPL ING
IPC: H03G11/00
Filed: 1979-07-18
Abstract: The limiter circuit modification eliminates the use of a Zener diode as the voltage sensing element. The Zener diode is replaced by a transistor (T) and voltage divider (R1,R2,R3,R4). The advantages offered by the substitution are twofold. Where a Zener diode is employed it is necessary to provide a filter circuit to suppress internally generated noise, for the diode may be called upon to operate on the noisiest part of its characteristic. Substituting a transistor eliminates the filters. It also gives a wide ranging choice of set points for the voltage regulator action. Using a transistor the set point depends only upon the relative magnitude of the ohmic values of the resistors in the divider chain. The modification simplifies the circuit construction, and at the same time improves performance.

Title: Safety device for target practice on firing ranges - uses modulated IR transmitters at target which are decoded electronically at weapon after passing through optical lens systems
Inventor: WARMT RUDOLF
IPC: F41J11/02
Filed: 1979-10-05
Abstract: The firing range consists of a target holder with a target disc on either side of which are two infrared transmitters emitting differently coded modulated IR beams. Two optical lens systems (6a,6b) are fixed to the barrel of the weapon (4) and are adjusted so that by directing the gun onto the target (2) the IR transmitters form images on sensitive transducers (7a,7b). These transducers feed separate amplifiers (9a,9b) whose outputs are taken to decoders (10a,10b) tuned to the different carrier frequencies of the transmitters. The two outputs of the decoders are connected to the inputs of an 'AND' gate (11) whose output signal feeds the locking mechanism of the weapon, allowing it to be fired. A second input channel from one decoder only (10a) allows loading and unloading of the weapon.

Title: Concrete pile driven plugged tube section coupling - involves bolts filling recess pockets formed in plugged and overlapping sockets ends
Inventor: LUDWIG HANNS-CHRISTIAN
IPC: E02D5/52
Filed: 1979-11-10
Abstract: Section ends are alternately formed as plugs and sockets, with bolting couplings, in sections of tubes driven in so as to provide site concrete piles. In each case the tube end (4) with a socket (3) overlaps its socket far enough for form and force-locking fitting against the inserted end (2) of the next section (1). Socket and inserted end have exterior distributed chord-type coupling recesses (5,6) combining to form tangentially accessible pockets to accommodate bolting pieces (8) which fill them. This permits rapid and easy pipe lengthening or shortening, and can transmit very powerful driving forces.

Title: Non-binding pad mounting for full disc brake - has sprung support to follow wheel distortion during vehicle cornering
Inventor: KLAUE HERMANN DR ING
IPC: B60T1/06
Filed: 1980-03-08
Abstract: The pad mounting for a full disc brake has the brake segments (7) on a support plate (7.3) secured on the hub support arms (9) with an axially sliding fit. A pressure cylinder is formed by two sections (12,13) which are splayed apart by hydraulic pressure, with a reaction force on the brake segments. The cylinder mounting is on a ball race (9.3) so that the brake segments adapt to the distortion in the wheel during braking and cornering. The alloy wheel twists during cornering and the limited play in the brake pads and disc would cause the brakes to jam or operate unevenly. The ball mounting provides a semi floating support for the thrust side of the brake, with a cup spring (22) to hold off the brake effect.
