    Abstract: The invention relates to a passive reply device for use, for example, in automatic wireless transmission of multi-place numerical information between it and an active interrogation device which are movable with respect to one another, particularly for track-bound transport apparatus, which comprises a high frequency line section having a high frequency antenna at one end, and short circuited at its opposite end, and a plurality of high frequency coaxial resonators extending transversely to and carried by such line section, with a number of resonators being proportional to the number of places of the information to be transmitted. The resonators consist of individual elements which are inserted in appropriate bores of the line section with a press fit. The tuning of the individual resonators is determined by the particular shape of the bottom wall of each resonator, with the resonators otherwise being similar in construction. The invention also involves a novel method of effecting the tuning of the resonators by taking like resonators, formed from a relatively soft malleable metallic material and deforming the respective resonator bottom walls in axial direction inwardly and outwardly, by the application of external forces thereto, thereby effecting frequency shifts in the respective resonators.

    Abstract: A transducer plate comprises electrically-conductive material on both sides and carries a respective piezoceramic on each side which has a respective electrode. The piezoceramics are electrically connected in parallel and are connected to the transducer plate via a respective, insulating adhesive layer. For the purpose of contacting the two inner electrodes, a passage is provided in the transducer plate and a connector ribbon is located between the adhesive layer and the inner electrode of one side and extends through the passage 2 to a position between the inner electrode and the adhesive layer of the other side. Only a single connector ribbon is therefore required for the pressure contacting of the two inner electrodes. Apparatus for threading the connector ribbon through the passage comprises bed dies having guide channels for the connector ribbon, whereby the connector ribbon is threaded through the passage either by way of a hob extruding die or by way of a curved-shaped surface of a guide channel.

    Abstract: A method and apparatus for separating twisted wires, such as switching cables, has a rotatably driven central shaft to which a cable to be untwisted is co-rotatably mounted so that the cable ends are free. The cable is rotated inside of a stationary protective housing, having paddles movably mounted in the interior of the housing to momentarily engage the free cable ends as the cable rotates. The wire ends are thus diverted from the rotating plane at least twice per revolution, and are thereby stimulated to oscillate such that untwisting results. The angle of inclination of the paddles is selectively adjustable to adapt to cables of various numbers of twisted pairs and differing wire gauges.

    Abstract: A piezo-electric acoustic transducer has two strip-shaped terminal leads for connection of an acoustic-electric transducer plate to an amplifier assembly of the microphone. Previously the two leads were manually soldered to Griplet soldering rivets on the component side of the circuit boards with the addition of soldering tin, and were insulated from the housing by means of an insulating ring. In the present invention, the terminal strips are directly soldered to the connector paths of a flat amplifier assembly and are electrically insulated from the housing by means of a tab. With this type of automated soldering and insulation, a work piece carrier is provided with a plurality of devices for the mounting of the flat assembly on the carrier plate.
