Title: Punctiform signal transmission from track to rail vehicle - has three optical couplers for control of light signal generators each with transmitter and receiver
Inventor: HINTZ HARALD ING GRAD
IPC: B61L3/12
Filed: 1980-12-08
Abstract: The transmission operates with modulated alternating voltages of a train control device, which has on the track side a preset number of modulation frequency generators, corresponding to the signals to be transmitted. The rail vehicles carry receivers, demodulators, and evaluators. For the transmission of a single signal of two individually or simultaneously switchable light signals (LSR, LSG) the control of the generators (140-143) is carried out by three optical couplers (OR1,OR2,OR3). Each coupler comprises a radiation transmitter (OR11) with an optically coupled radiation receiver (OR12). The radiation transmitter of the first coupler, or both transmitters (OR21, OR31) of the second and third coupler, are connected to the circuit (L6,L8) of the signal lamp of one or the other light signal. The radiation receivers (OR12, OR21) of the first two couplers serve for enabling of the associated generators. The receiver (OR32) of the third coupler blocks the first coupler.

Title: Stringed instrument
Inventor: HOPF DIETER
IPC: G10D3/02
Filed: 1981-01-20
Abstract: A stringed instrument, especially a guitar, is to be equipped, in the region of the bridge base (15) mounted in vibration-transmitting connection with the casing of the instrument body, with at least one removable or exchangeable mechanical vibrating element (10) projecting into the cavity of the instrument body (16). When a string is struck, such a vibrating element (10) absorbs a correspondingly high vibrational energy, thus leading in the first place to an initial damping of the struck string. When the natural vibration of the struck string is damped as a result of the emission of the sound, the mechanical vibrating element feeds its own vibration back to the vibration of the string, in order to reinforce the vibration of the string when the sound fades away. The mechanical vibrating element (10) can be designed preferably in the manner of a pendulum, consisting of an inherently rigid pendulum rod (12) fastened rigidly to a plug part (11) and of a weight attached to the free end of the said pendulum rod (12). To receive the mechanical vibrating element (10), bores (18) made to narrow conically towards the inside of the instrument body (16) are preferably arranged in the region of the bridge base or directly in the bridge base. <IMAGE>

Title: Device for vacuum extraction
Inventor: SANNER BERT ING GRAD
IPC: A61B17/44
Filed: 1981-09-29
Abstract: In order to reduce the risk of brain damage caused by the scalp snapping back when the suction cup is removed during vacuum extraction, there is additionally provided in the inside of the suction cup a tissue-retention arrangement which is under the same partial vacuum as the suction cup itself. The tissue-retention cup is connected via a spring to the traction grip, so that only slight traction forces act upon it and a sudden removal from the scalp is ruled out. Since the inside of the tissue-retention arrangement is connected to the inside of the suction cup via a throttle arrangement, the partial vacuum in the tissue-retention arrangement is maintained for some time after the removal of the suction cup, so that the scalp can return slowly to its normal position.

Title: Device for cutting frozen material
Inventor: DOERSCHNER ULRICH
IPC: B26D7/02
Filed: 1981-11-13
Abstract: The invention relates to a device for cutting frozen material, having a guillotine-like cutting mechanism, which is constructed such that the frozen material is firmly held during the cutting operation. The object is to reduce the energy consumption and the time losses when detaching and holding the frozen-material block during the cutting. The object is to develop a block-holding device such that an automatic continuous stroke limiting of the pressure plate to the frozen-material passage height takes place. According to the invention, a touch sensor having a sensing edge and an impact surface is movably arranged on the pressure plate of the block-holding device. A signal transmitter is situated on the pressure plate for triggering the control processes. The impact surface of the touch sensor is situated at an acute angle to the supporting plate of the frozen-material block. The pivot point of the touch sensor was chosen such that it is situated on the pressure plate close to the knife holder. A stop is attached to the pressure plate for limiting the movement of the touch sensor. The impact surface of the touch sensor is formed from an acute-angled moulding. Energy- and time-consuming strokes of the block-holding device as far as the end position are avoided. <IMAGE>

Title: Device for portioning and compacting foods
Inventor: REIFENHAEUSER TONI
IPC: B26D7/06
Filed: 1981-12-02
Abstract: In a chamber (3), portioned foods are compacted by a side wall of the chamber (3) being designed displaceably in such a manner that it can be transferred from a position defining a maximum volume of the chamber (3) into a position defining the minimum volume of the chamber (3). The position defining the maximum volume of the chamber (3) of the side wall, which is formed from a flap (4) or a prepressing ram (4'), is steplessly adjustable in a defined range by a locking member (5) which limits the pivoting movement of the flap (4), or an adjustment screw (5') which limits the starting position of the prepressing ram (4'). As a result, it is possible to produce portions with a different degree of compaction for a subsequent cutting process. Before the compaction process starts, the cutting member (1), which is essentially driven in the same direction as the flap (4) or the prepressing ram (4'), is transferred into a position blocking the filling cross-section of the chamber (3) so that no material can escape from the chamber (3) as a result of the compaction process. <IMAGE>
