Title: Test system for subassemblies in telephone exchange - compares outputs of pairs of identical synchronised subassemblies to detect differences
Inventor: SAUTER HERBERT DIPL ING
IPC: H04M3/26
Filed: 1979-03-15
Abstract: The test system routinely checks all subassemblies used by an exchanged by comparing the functioning of two identical subassemblies operating in parallel and synchronously. One subassembly operates within the exchange as normal, whilst the second subassembly receives the same input signals as the first but its outputs are not fed to the exchange, instead they pass to the comparator. The comparator also receives the outputs of the first subassembly (which are fed to the exchange). If the two sets of outputs are found to differ the comparator initiates the recording of the output signals and if necessary also the input signals. The exchange does not receive those output signals that are produced by a subassembly under test and therefore supposed faulty.

Title: Radio control system using PWM - forming pulse packets which are averaged at receiver to generate reference potential for pulse regeneration
Inventor: ESSL HARTWIG
IPC: H04L25/49
Filed: 1979-09-06
Abstract: The radio control system, for time multiplexed transmissions, has the time sum of pulses of different potentials equal to one another within one pulse packet. At the receiver a reference potential is generated by averaging the potentials of the received pulse packets. The reference potential is used for evaluating the received potentials and for generating the received pulses. The advantage lies in simplicity and noise immunity in that the reference signal needed for pulse regeneration is derived directly from the pulse packets. The arithmetic mean is constructed using an integrator.

Title: AM radio tuner with HF amplifier stage - has aerial circuit output signal applicator to amplifiers with high and low gain respectively
Inventor: O'KEEFE GERALD T
IPC: H03G3/30
Filed: 1980-06-12
Abstract: The high frequency amplifier stage has an output line to a mixer stage, as well as input lines from an aerial circuit and a source of automatic amplification control voltage, proportional to the level of the signal output in the aerial circuit. The latter circuit output signal is applied directly in parallel to a high and low rate amplifier respectively. The amplifier stage has a fixed bias device for switching-on the high gain amplifier and for switching-off of the low gain amplifier, using the biasing voltage on absence of any signals from the aerial circuit. An applicator feeds the automatic amplifying control voltage to the circuit controlling both amplifiers. Thus the amplifying effect of the high gain amplifier is considerably reduced and that of the low gain amplifier considerably increased in response to the increase of the automatic amplifying control voltage.

Title: Programme sequence control in a multi-programme language teaching system
Inventor: MATJASIC JOSEF
IPC: G09B5/12
Filed: 1981-01-24
Abstract: To distribute the sound and switching signals present within an electronically controlled electro-acoustic multi-programme language teaching system between the circuits of a central switching station and those of a number of student's stations, a control value with several inputs and outputs is provided which, by means of preprogrammed logical line connections provides the possibility that each learning programme can be called up from each student's station by a fast copying process and disadvantageous mutual interaction is avoided in the case of multiple selection of the same programme. These mechanical or electronic line connections can be controlled at the central switching station. They can be cancelled here at any time as freely determined by the controller or a particular learning programme can be mandatorily connected to one or a number of student's stations. The state of programme allocation is transferred to the student's stations via suitable signalling devices.

Title: Electronic musical instrument in a vehicle, for example in a motor vehicle
Inventor: NARDIN H PETER DIPL ING
IPC: B60Q5/00
Filed: 1981-04-27
Abstract: The invention relates to electronic sound and music generators as vehicle-mounted hazard-warning and monitoring systems in vehicles, in particular in the cockpit of a motor vehicle, in conjunction with display instruments which operate on an analog basis and in conjunction with digital information and display systems. In this arrangement, the optical reading of the instruments which serve for traffic safety is to be promoted and facilitated by means of audible signals on the basis of simple electronic sound and music generators or also on the basis of magnetic tape playback devices for complete sequences of tunes. Furthermore, melodies can be preselected by changing ROMs in order to conform to general tastes. In contrast with the arrangement of instruments in the cockpit of an aeroplane, the arrangement of groups of instruments in the cockpit of a motor vehicle by means of additional audible signals in the form of sequences of sounds and tunes has a large influence on the driver of the vehicle since he determines the road holding and maintains the direction of the motor vehicle steered by him on a two-dimensional surface.
