Title: Conference circuit for PBX - has switches time multiplexing transmit and receive amplifiers to line
Inventor: STEUER BERND DIPL ING
IPC: H04M3/56
Filed: 1978-07-25
Abstract: The conference provides each subscriber with transmit and receive amplifiers. Both amplifiers at each subscriber station are mutually decoupled by time multiplexing using clocked switches. The output of the transmit amplifier is connected via a transmit switch to the transmission line linking the subscriber stations. The output of the receive amplifier is connected via a receive switch to the transmission line. The transmit switches are operated sequentially so that no two are closed at the same time. The receive switches are similarly controlled.

Title: Sandwich structure semi-finished constructional material - comprises tubes of fibrous material impregnated with synthetic resin and glued together
Inventor: UFER ERICH DIPL ING
IPC: B64C1/00
Filed: 1978-08-19
Abstract: The semi-finished material is for lightweight sandwich structures, being made of small tubes of fibrous material such as paper. The tubes are impregnated with synthetic resin, either in the moist or dry state, assembled and glued together, and hardened to form core-filling material. They can be wholly or partly filled with foam material to prevent water absorption or provide additional stiffness. Additional fibre such as carbon fibre can be mixed in with the fibre material and aligned in the tubes, being typically used as a coating for the latter, running in the lengthwise direction or intersecting diagonally.

Title: Control for IC engines fuel injection pump - has solenoid-operated valve de-energised to stop engine by returning pump output directly to fuel tank
Inventor: KNORRECK PETER ING GRAD
IPC: F02D1/02
Filed: 1978-08-31
Abstract: A fuel injection pump includes a control member which releasably engages a stop connected to a fuel feed regulator. The control member is biassed by a cut-off spring to displace the regulator towards its zero position for stopping the engine. To start the engine, hydraulic fluid from the feed pump displaces the control member against the force of a spring displacing the regulator towards a starting position. The device coupling the control member with the regulator consists of a ball and spring socket. The coupling is disengaged by the movement of the control member to a position beyond the "start" position so that the regulators is free to move in response to a governor.

Title: Remote control manipulator gripping tool - has backrest with granule-filled inflatable and evacuable bag formed integrally with gripping tool
Inventor: SCHMIDT INGO DIPL ING
IPC: B25J15/00
Filed: 1978-09-15
Abstract: The manipulator gripping tool has a deformable jaw consisting of an elastic bag filled with granules which move easily against each other. The bag is fitted against a backrest forming an integral part of the gripping tool. By means of a channel the bag can be connected with the atmosphere or put undernegative pressure by evacuation. At the beginning of the gripping operation the workpiece is pressed against the yielding body of the bag while it is under atmospheric pressure. When the bag adapts its shape to that of the workpiece, air is evacuated from the bag and the subsequent vacuum keeps the granules inside the bag in a solidified state, so that a positive hold on the workpiece is achieved.

Patent DE-2900358-A1 (DE)
Title: Central heating system furnace - has fuel gas flow detector switch, thermostat and position indicator switches coupled to circuit which controls damper drive motor
Inventor: SATTMANN KARL
IPC: F23N3/08
Filed: 1979-01-05
Abstract: A gas furnace employs an exhaust flue damper driven by an electric motor equipped with position indicating switches. A gas flow detector switch supported in the gas line has a vertical passage and a valve member gravity biased into a rest position in which it blocks gas flow through the passage. Fuel flow through the line creates a differential pressure on the valve, raising it above the rest position. Circuitry interconnecting the damper drive and position indicating switches and the gas flow switch with the furnace thermostat and the gas line control valve, positions the damper in a closed position when there is no gas flow to the furnace.
Patent DE-2903146-A1 (DE)
Title: Trigger switch for pistol grip of electric drill - has locking lever and spring attached for optional permanent engagement
Inventor: SCHNIZLER JUN ALBRECHT ING GRA
IPC: H01H13/62
Filed: 1979-01-27
Abstract: The trigger switch (3) built into the pistol grip of an electric drill, incorporates an auxiliary switch (16) which enables it to be easily released from a locked position. It is operated just as easily by left handed as by right handed persons. The auxiliary switch is mounted on a pin (9) passing through the trigger itself so that its upper hooked end (12) can lock behind a nose (13) on the casing. When the trigger is pulled against the force of a spring (6) behind it, this hooked end moves backwards with the trigger, and is released. It is then swung into a disengaged position by a second spring (15) behind it, housed in a recess inside the rear of the trigger, and is not engaged again unless pulled back against the force of the latter spring.

Title: Drain valve automatic shutting mechanism - has splash-proof sensor moistened by reverse flow in pipe
Inventor: BIGALKE ERHARD DIPL ING
IPC: E03F7/04
Filed: 1979-03-16
Abstract: The mechanism automatically shuts a slide valve in a pipe, partic. a cellar drain pipe, handling fluid, on reversal of flow. A splash-proof liq. sensor is mounted in the pipe before the shut position of the valve, when seen in the reverse flow direction.

Patent DE-2912308-A1 (DE)
Inventor: MORHARD ALFRED
IPC: B21C37/12
Filed: 1979-03-28
Abstract: A method of making a multi-layer tube includes the steps of pre-heating two elongate metal strips and bending each to a substantially arcuate curvature. Each strip is then wound helically with abutting edges, one strip being closely concentrically wound around and axially offset with respect to the other, so that the strips define a cylindrical tube. A synthetic resin is applied between the strips and to the interior of the tube during the winding step and is then pre-cured. Thereafter, a coating of the synthetic resin is applied to the exterior of the tube and then all of the synthetic resin is fully cured.
