Title: Surveillance of parallel power generators - uses service parameter measurement with threshold detector
Inventor: UDVARDI-LAKOS JANOS DIPL ING
IPC: H02H3/36
Filed: 1975-02-24
Abstract: The system uses a '2 from 3' comparison and each power generating group has sensors to measure the service parameters. Each group has a protection stage and some method by which it is taken out of service. Differential service parameters are sensed by a threshold detector which can take the groups out of service. This surveillance system monitors the failure of performance of one power generator from a multiple of such generators that have parallel and common outputs.

Title: Signal selector for radio communications system - has blocking circuit briefly blocking frequency sweep and actuating identifier
Inventor: BROEMSSEN KNUT THORKEL VON DIP
IPC: H04W48/16
Filed: 1975-05-14
Abstract: The signal selector, for a radio communications system, has a blocking circuit between the discriminator and the flipflop circuit. This blocking circuit responds to a control signal from the discriminator and briefly acts on the flipflop circuit such that this flipflop circuit output voltage is held constant. The output voltage controls the local oscillator, and when held constant in this manner effectively interrupts the scanning process for the short time for which the blocking circuit has blocked the flipflop circuit. During its blocking interval, the blocking circuit alss actuates the identifying circuit.

Title: Address-multiplex concentrator for data transmission - prevents loss of messages at peak loads of system with polarity change transmitted in sequence
Inventor: KAMMERL ANTON DR ING
IPC: H04L12/52
Filed: 1975-08-12
Abstract: The method is for the transmission of data signals between a number of subscriber lines through a common channel, for signals consisting of polarity alternation coded messages with an indicator for the polarity change, a line address, and time code date, in which the polarity change is transmitted in sequence of the time of incidence together with the line according to the holding procedure. The polarity change messages are written at the transmitter into a memory containing several telegrams (ZSP) so that if several messages are held they are transmitted in sequence. If a large number of messages are held the content of the time code in formation of the messages is held in the form of one or more time code bits in the memory in a predetermined time raster and raised by one on transmission.

Patent DE-2550444-A1 (DE)
Inventor: HOLZAPFEL KLAUS DIPL ING
IPC: B61L3/12
Filed: 1975-11-10
Abstract: In a train protection system with intermittent automatic transmission of information from the railway tract to the trains, the trains determine the permissible travel speed on the flat and on inclines from the information transmitted to them as they pass fixed transmission devices, the said information relating to target speed (in VS) and distance from a destination (in WS) for their respective location. The respective lower value of the two speeds is selected (in V1) and compared with the vehicle's own maximum speed (in V2). Subsequently, the respective lower value of the two speed variables is determined and compared with the output signal of a speed signal generator (VG) for the actual speed of the vehicle (in V3); an automatic braking stop of the vehicle is brought about as soon as the actual speed exceeds the permissible travel speed formed from the maximum permissible speed for the route and the vehicle's own maximum speed. As a result, a reliable selective braking of the trains is possible without the fixed transmission devices having to transmit information relating to possible inclines on the route to the trains. The transmission devices which act in an intermittent automatic fashion can be arranged at different distances in front of hazardous locations. <IMAGE>

Title: Carrier for sliding clasp fastener with separate latches - is knitted fabric with latches sewn to bead threads
IPC: A44B19/34
Filed: 1976-06-15
Abstract: A carrier for a sliding clasp fasteners, consisting of a narrow warp knitted fabric with a wale structure of ribs and grooves, has a thickened edge for a row of latches. For the attachment of a row latches consisting of separate stampings or castings of metal or synthetic material, and so that they can be set astride the edge of the carrier, this is thickened by bead thread(s) laid into a groove close to the edge. The bead thread is sewn by a seam the stitches of which penetrate the fabric in the groove. The thickened edge may be improved by a second bead thread secured to the opposite face of the fabric in line with the groove holding the first bead thread. The seam is a double chain stitch seam the threads of which are embedded in the bead threads. The ground fabric for the carrier is fully synthetic yarn, e.g. polyester staple fibres, and for pref. the two bead threads with the sewing threads, are of cotton. This makes it possible to use as the carrier for a fastener, the rows of latches of which are separate details of metal or plastic, a warp knitted tape. The bead threads distribute the lateral loading on the feet of the latches so that they can be tolerated.

Title: Pneumatic spiked tyres for clear or icy roads - the spikes being kept out of contact with a clear road surface by webs
Inventor: BELLAN HEINRICH
IPC: B60C11/16
Filed: 1976-12-08
Abstract: Pneumatic spiked tyres have the same road holding and braking characteristics on both clear or ice or sleet covered roads in that the spikes which are let into the tyre periphery in axially spaced peripheral arrays are delimited bilaterally by one or more divergently directed supporting webs. In the case of a clear road surface, the webs keep the spikes out of contact with the surface due to high frictional resistance between webs and surface. In the case of an ice or sleet covered surface the reduced coefficient of friction between the webs and the surfaces causes the webs to deflect bilaterally to bring the spikes into contact with the surface.
