Patent DE-2836485-A1 (DE)
IPC: G07F17/12
Filed: 1978-08-21
Abstract: When the bolt of the coin-insertion lock is closed in reverse, the individual key (34) located in the lock cylinder (10) cannot be withdrawn. For this purpose, the bolt has to be closed forwards. If the forward closure of the bolt takes place without a coin, the blocking boss (20) of the blocking pawl (17) butts against the blocking edge (22) of the bolt (19), thus making it possible only to close the bolt (19) forwards to a limited extent. In order to close it forwards completely, a coin (35) has to be introduced. This is held by the supporting shoulder (33) and the pin (32). During the forward closure of the bolt, the coin (35), with its edge face, lifts the blocking pawl (17) via the blocking boss (20). In the final phase of the forward-closing movement, the coin-holding rocker (30) butts with its edge (30') against the portion (9') of the lock cover, with the result that the coin (35) is released. When it slides downwards, it comes up against the holding projection (36) and the supporting strip (37) of the lock case (1). Only when the bolt (19) is closed in reverse does the coin (35) fall into the coin-return compartment (38) of the lock mounted on the inside of the door. This lock is simple and cost-saving, since a saving of lock components is achieved, whilst a locking mode unsusceptible to faults is obtained. <IMAGE>

Title: Automatic disconnection of unwanted part of radio programme - filtering certain part of AF spectrum and providing control voltage, after amplifying
Inventor: MATTERN JUERGEN DIPL ING
IPC: H04B1/16
Filed: 1980-06-19
Abstract: The disconnection can take place while a programme is being received, e.g. to switch off advertising matter. Certain portions of the a.f. spectrum of a radio programme are filtered out, amplified, and used for generation of a control voltage. The latter is used for transmission of a switching signal at the start of the radio selection via a switching stage. The signal blanks out the programme portion, and/or provides an automatic programme change. The switching stage either disconnects the receiver loudspeaker, or reduces the amplifying rate of an end stage. Pref. the signal of the switching stage selects the frequency of another radio transmitter. At the beginning of the programme section the switching signal may start a timer which cancels the blanking out after an adjustable time interval, or possibly selects again the frequency of the originally selected radio transmitter.

Title: Overload indicator for electrical distribution networks - uses magnetic field induced by overload current to stir up powder in liquid-filled capsule
Inventor: VIS SIETSE
IPC: G01R19/165
Filed: 1980-11-03
Abstract: This device for locating short circuits and overloads in electrical distribution networks, and is mounted on a vertical conductor (3). It consists of iron brackets (4 and 5) in which a glass capsule (2) is mounted. The capsule contains a clear liquid, an insoluble coloured powder and a magnetic disc (1). An overload current induces a magnetic field via the iron brackets, causing the disc to vibrate, stirring up the powder in the liquid. After the overload ends, the liquid starts to clear from the top of the capsule as the powder slowly settles. There is a non-magnetic spacer between the two brackets. The strength of the field due to a particular current is proportional to the thickness of the spacer, so that different thicknesses of spacers can be used to set the threshold at which the indicator starts to operate.

Title: Method for carrying out cold-pump and heat-pump processes on the compression principle with solution circulation
Inventor: MALEWSKI WERNER DR ING
IPC: F25B25/02
Filed: 1981-01-02
Abstract: The invention relates to cold-pump and heat-pump processes which are operated with a complex mixture as a working medium, the latter being evaporated at a sliding temperature and the mixture vapour being compressed and resorbed again by the deconcentrated solution. The solution mixture restored to the former concentration is conveyed back to the evaporation point, thereby closing the circuit. The process-related operations are coupled material and heat transport cycles which, in the event of changes in concentration, take place in counterflow and during the compression and the technical practicability of which has not hitherto been solved in terms of either the appliances or the compressor. The new method of invention allows technical constructions and circulation-process efficiencies which are well above those of the compression principle with unitary working media. Because, according to the invention, the circulating deconcentrated solution is injected into the compressor during the compression of the mixture vapour, as shown in the diagrammatic drawing, the following are achieved: cooling during the compression operation, with virtually isothermal compression, direct heat exchange without a transmission surface, oil-free compression with high compression efficiencies. An advance into the temperature range of between 100 and 200 DEG C, with vapour generation from waste heat, is thus possible. <IMAGE>

Title: Device for generating a frequency-modulated signal
Inventor: LEITL FRANZ DIPL ING
IPC: H03C3/09
Filed: 1981-01-22
Abstract: A part of the frequency-modulated output signal of a voltage-controlled oscillator (1) is coupled out and supplied directly, on the one hand, and delayed by the time  tau , on the other hand, to a phase discriminator (3). The output signal of the phase discriminator triggers a flip flop (7), which outputs a periodic squarewave signal, the period of which, in the settled state, is equal to the period of the modulation signal and which, on the one hand, is compared with nominal values and, on the other hand, controls a switching device (11). From the comparison of nominal and actual values, a control signal is generated which controls the amount of the amplitude of a direct voltage signal, generated in a direct-voltage generator (10), which is supplied with positive and negative signs to the switching device (11). The output signal of the switching device (11) is supplied to an integrator (12) and the output signal of the latter is the control signal for the voltage-controlled oscillator. <IMAGE>
