Patent DE-2832796-A1 (DE)
Title: Metering circuit for small PBXS - uses digital blocking signal to prevent double counting
Inventor: BRAUNBECK WERNER
IPC: H04M15/34
Filed: 1978-07-26
Abstract: The metering circuit for small p.b.x.s. has meters associated with each subscriber connection. The meters are controlled by a count pulse provided by the respective exchange contact and control circuit. A digital blocking potential is applied for a short time interval synchronized to the arrival of the local call charge pulse each time the exchange line is occupied and each time the count pulse is recorded. The blocking voltage prevents the initial state of the control circuit from changing. This applies to all other control circuits with the exception of that one which has prepared the appropriate gate associated with the meter. This avoids double counting of a pulse occurring during the call transfer interval.

Title: Telephone call-charge display system - has knobs to set tariff rates and calculates charge from tariff rates and call duration
Inventor: WOBBERMIN HEINZ
IPC: H04M15/28
Filed: 1978-07-31
Abstract: The call-charge display system has an evaluation circuit receiving the call metering pulses sent to the telephone set from the exchange. The evaluation circuit calculates the cost of the telephone call from the tariff rate and the call's duration. The calculated cost is displayed. The tariff rates can be entered in the evaluation circuit using controls knobs. The system does not require direct wiring to the telephone set. The evaluation circuit reconstructs the dialled telephone number from the noise pulse generated during dialling.

Title: Switching delay circuit for amplifier network - has controllable transistors connected in signal path from end stage transistorised circuit
Inventor: KOEPKE WOLFGANG ING GRAD
IPC: H03G3/34
Filed: 1978-12-15
Abstract: The switching delay circuit is intended for audio appts. amplifiers with an input and output stage network respectively, in which undesirable noise during switching-on may be suppressed. A controllable electronic device, such as a transistor (20, 30) is connected in the signal path of transistors in the output stage network (25, 35). This connection is pref. carried out via a time element. The controllable transistors are connectable as a short-term short circuit path for the signal. Alternately, the controllable transistors may be connected in the signal path as a controllable negative feedback. An operational transistor may also form the controllable device. The circuit ensures that the input signal voltage is controlled in front of the output stage. Thus low signal power has to be processed without application of any relays, while maintaining favourable noise suppression for loudspeaker or headset.

Title: Safety ball valve with damper - has non return and suction valve between medium and damper plunger chamber
Inventor: BRUNNER RUDOLF
IPC: F16K17/04
Filed: 1979-01-18
Abstract: The safety valve has a ball pressed by a spring against a seat and against the flow direction. To damp the closing movement, there is a spring-loaded plunger upstream of the seat, with a mushroom-shaped tappet acting against the ball. The piston works in a chamber connected via a throttle to the flowing medium. Between the chamber (11) and the path of the medium (3) is a non-return and suction valve. When the pressure in the medium path momentarily exceeds that in the chamber this valve (22) opens and forms an additional connection.

Title: Extended range acoustic guitar - has bridge on neck side of sound hole and has normal cut-away portion of body
Inventor: LOHBERG PETER ING GRAD
IPC: G10D1/08
Filed: 1979-02-17
Abstract: An extended range acoustic guitar has the sound hole displaced towards the bottom end of the case and the bridge set on the neck side of the hole. This allows the fingering to reach the shorter end of the strings with just a normal cutaway so that a wider range of notes is possible on each string. The strings are taken over the bridge and down through the top of the case for securing on the inside rear wall of the case. This enhances the sounding effect of the case.

Title: Monitor for period of nuclear reactor - gives alarm if reactor power signal rises so fast that reference signal cannot follow
Inventor: JOHANSSON LARS OVE
IPC: G21C17/14
Filed: 1979-03-15
Abstract: The period of a nuclear reactor is supervised by generation of a reference signal, R, which is compared with the power signal, S, and, depending on the results, an outgoing signal, R1, which influences R to follows S is generated. The time derivative of R is set not to be greater than the max, allowed derivative for S and if the power increases so fast that the level of S is different from that of R and alarm level signal, L, is generated. The level of L corresponds to that of R multiplied by a factor (a) greater than 1. An alarm signal starts if the level of S is the same or greater than that of L. A device for monitoring the reactor period is also claimed. The method is partic. suitable for monitoring a power signal comprising several linear areas, e.g. the IRM part of the SRM-IRM system.

Title: Waste gas flaring-off burner - has flaps thrust mechanically into position shutting mixing tube primary air inlets
Inventor: BEYER JOHANNES DIPL ING
IPC: F23G7/08
Filed: 1979-08-25
Abstract: The gas burner is particularly for flaring off waste gas. It has a gas outlet nozzle discharging into a mixing tube extending upwards and containing lateral inlets at the nozzle opening for primary air. These inlets can be shut by flaps thrust by mechanical pressure into the shut position. The flaps are so mounted that the pressure difference generated by the gas flow from the nozzle between the static pressures on outside and inside causes them to move into the open position. The inlets and flaps can be spaced round the periphery of the mixing tube.

Title: Air cleaning plant for removing noxious impurities - where wash liq. is sprayed into air and then removed via sepg. drum
Inventor: BASSFELD JOACHIM DIPL KFM
IPC: B01D47/06
Filed: 1979-08-31
Abstract: Waste air, contg. solid-, liq.-, and/or gaseous-impurities is fed through an inlet duct (3) into a separator drum (5). On the axis of duct (3) is at least one nozzle, spraying a wah liq. into the stream of air, and also a baffle which imparts a swirling or rotary motion to the air stream. The wash liq. is fed from a tank by a pump to the nozzle, and then falls into the sump of drum (5), from which it drains back to the tank. The clean gas then flows through an exit duct (9) coaxial with duct (3). Several such gas washers may be used in series and employing several wash liqs., and the lower part of the drum (5) may be used to hold a wash liq. instead of employing a separate tank. Contaminated air flowing at up to 10 m/s can be cleaned with virtually no drop in pressure.

Title: Exertion percussive force on workpiece - has working chamber pressurised by working fluid and damping occurring when working piston enters annular piston recess at end of stroke
Inventor: BALTSCHUN HORST
IPC: B21J7/28
Filed: 1979-09-28
Abstract: The device for exerting percussive forces on workpieces has a cylinder (1) with pistons (3, 5). The cylinder is divided by the annular piston (5) into a gas filled chamber (7) and a working fluid chamber (6). The latter chamber is initially charged with a predetermined quantity of pressurised working fluid. Damping at the end of the working stroke occurs when the piston enters a recess (9) in the annular piston (5). The volume of the gas-filled chamber increases during the working cycle since the annular piston moves towards the cylinder end face. The increase is accompanied by a fall in the pressure of the pressurised gas. The pressurised gas in the pressurised gas chamber returns the pistons into their end positions.

Title: Control of coin-operated gaming machine - using magnetic disc to store data and control operating cycle
Inventor: GAUSELMANN PAUL
IPC: G07F17/32
Filed: 1979-10-26
Abstract: A coin-operated gaming machine, e.g. slot machine uses a magnetic disc to store data and control information. The use of the disc avoids the loss of stored data when power is lost. The magnetic disc is driven by a coupled electric motor. The disc has two tracks, one for the storage of data that has associated read, write and erase heads, and a control track that has only a read head. Attached to the spindle of the disc is a cam that controls the start and end points of a cycle. The output of the control track head is fed to a decoder that generates outputs to control the cycle. A counter and comparator determine the winning combination states.
