Title: Apparatus for multiple use of the end sensing of a cassette tape
Inventor: GAWANKA JOACHIM
IPC: G11B23/087
Filed: 1985-03-26
Abstract: Apparatus for multiple use of the end sensing of a cassette tape by deflecting the light path, which usually runs rectilinearally, and an additional movable diaphragm (14), which initiates a switching function other than that provided, depending on the direction of rotation. On loading the existing tape cassette in a commercially available cassette player, the light signal of the provided light-transmitting element (9) is emitted via the input prism (12) and the light guide (11) to the output prism (13), without loss past the cassette tape (5) to the light-receiving element (10). On actuating the "play" or "forward" function button, the tape reel (4) is set rotating to the right and, by means of the sliding link (15) pushes the diaphragm (14) between the output prism (13) and the light-receiving element (10). The normal sequence of events is ensured, as in the case of a normal tape cassette, until at the end of the tape (5) the transparent tape (6) appears on the reel (3) and the normal end-of-tape switch-off can be performed. The then automatically occurring rewinding, or else a rewinding manually actuated in the meantime, has the consequence that the tape reel (4) is set rotating to the left and the sliding link (15) brings the diaphragm (14) into its other end position, this clearing the light path from the output prism (13) to the light-receiving element (10) and consequently initiating the "end-of-tape stop" function. Rewinding is consequently ruled out. Each ... Original abstract incomplete. <IMAGE>
Patent DE-3511661-A1 (DE)
Title: Ballast apparatus for gas-discharge lamps
Inventor: SOEYLEMEZ ALI-IHSAN
IPC: H05B41/295
Filed: 1985-03-29
Abstract: The apparatus contains a free-running semiconductor chopper as an AC voltage generator, and LC series-resonance circuit which is acted on by the AC voltage and has a capacitor in parallel with the lamp, and a feedback loop which is provided with a saturation current transformer (Tr1, Tr3) which determines the frequency. In the starting phase, the apparatus oscillates at a frequency fz which is above the resonant frequency fro of the undamped series tuned circuit, and, after starting, it oscillates in normal operation at a frequency fn < fro. The value of fz is shifted relatively severely with respect to fro by relieving the load on the transformer secondary, during the starting phase. Advantages: the lamp is preheated and the current-carrying components are protected in this phase. The relief can be implemented, for example, by means of an NTC thermistor (NTC1) or by means of a transistor (T11) in the circuit of an additional secondary winding (n10). The NTC thermistor at the same time provides a certain amount of temperature stabilisation and, if a transistor is used, comprehensive power stabilisation can be achieved. Main field of application: operation of fluorescent lamps using MOS switching transistors. <IMAGE>

Title: Method for synchronising and routing in partially meshed communication networks
Inventor: KLOSTERMANN DETLEF DIPL ING
IPC: H04W88/08
Filed: 1986-05-06
Abstract: A station newly switched on searches for the control channel on which all stations are transmitting control blocks consisting of synchronisation block, master or slave identification and routing table under random control within a predetermined time limit; when it detects the control channel, it locks to the received TDM frame and transmits control blocks with slave identification. If it does not detect the control channel within the time limit, the station newly switched on generates a TDM frame and randomly seizes the control channel for transmitting control blocks with master identification. If it detects a number of different control blocks with master identification, the station newly switched on checks the various control blocks for the extent of their routing tables and accepts the station having the most extensive routing table as master station; to the other stations it issues, after having in each case locked to their TDM frames, the command for stopping their transmissions and subsequent resynchronisation; it then locks to the TDM frame of the accepted master station and transmits control blocks with slave identification.

Title: Detonation signalling device
Inventor: NAVE PETER DR
IPC: G08B17/12
Filed: 1986-06-04
Abstract: The present invention relates to a detonation signalling device for signalling the frequencies and intensities of spectral radiations from detonations of long-range projectiles. Different detonations are determined on the basis of their type and origin by continuously measuring and assessing the time behaviours of the spectral radiations in the IR and UV bands. A plurality of spectral channels, whose frequency ranges differ and which have appropriate sensors, are used for this purpose. The detonation signalling device is in this case constructed such that it can be detached from the projectiles and, after ejection, is automatically and forcibly oriented in the direction of the target by a parachute.

Title: Device for producing patties
Inventor: MUELLER FRANZJOSEF
IPC: A22C11/00
Filed: 1986-06-27
Abstract: The device is used to produce patties made of a core composed of one kind of sausage meat and a casing which surrounds the core and is made of another kind of sausage meat. It contains a hydraulically or pneumatically controllable reciprocating plate and two filling pipes which are arranged above and concentrically with the latter. The said plates are connected to filling devices for the two kinds of sausage meat. To produce a patty, a container is placed on the plate. The latter is then raised, causing the container to be pushed across the two filling pipes. Then the two kinds of sausage meat are pressed into the container via the filling pipes as the plate, and therefore the container, are lowered. In a known device of this type, the two kinds of sausage meat can become mixed up. To ensure precise mutual delimitation of the two kinds of sausage meat, according to the invention the inner filling pipe is situated opposite the outer filling pipe. This ensures that the sausage meat first emerges from the outer filling pipe and has already adopted a specific shape before the sausage also emerges from the inner filling pipe as the container starts to descend.
