Title: Highway radio telephone system - makes duplex signalling channel allocated to each radio band between vehicle and station
Inventor: PORTSCHT RAINER DR ING
IPC: H04W72/04
Filed: 1975-08-23
Abstract: A radio telephone system for highways uses stationary transmitters and stationary or moving subscribers. It permits a large number of speech channels with a highly efficient channel access. Each of the 7 to 9 radio traffic ranges receives an allocated duplex signalling channel for signal transmission and information exchange between stationary and mobile stations. This applies both in the dormant period and during the making of a connection. This achieves a decoupling of signals transmitted by the stationary transmitter stations of adjacent radio traffic ranges. These duplex signalling channels are used in both signalling directions.

Title: Drive circuit for loudspeaker - has feedback dependent on difference between membrane movement and input signal
Inventor: PUETZ GERT ING GRAD
IPC: H04R3/00
Filed: 1975-08-27
Abstract: The drive circuit, for a loudspeaker, has a sensor detecting the actual acceleration experienced by the membrane and passing a signal proportional to this acceleration to a comparator (8). The comparator compares it with the loudspeaker (2) input signal to produce a difference signal. The difference signal is applied to the input of a PID regulator (10) whose output is coupled back into the loudspeaker input circuit. The advantage of the circuit lies in its not just using a feeback signal dependent on membrane acceleration but one that compensates for the difference between membrane movement and input signal.

Title: Flat magnetic card reader head - uses ferrite cores with square loop toroids switched between two stable states
Inventor: FAYLING RICHARD E
IPC: G06K7/08
Filed: 1976-08-27
Abstract: The magnetic card reader comprises a flat rectangular housing (3) containing a matrix of individual data bit detectors. Each detector element consists of a ferromagnetic torroid (13) having a hysteresis curve giving two stable states of remanence. A pair of conductors runs through the centre of each torroid for control and detection purposes. The drive or control line carries an alternating waveform which normally drives the ferrite core from one stable magnetic state to the other. If however, a magnetic data bit in the surface of a magnetically-encoded card or document is brought into close proximity with the core, the change from one to the other of the magnetic states is inhibited. The detector or read conductor signal is altered accordingly and acted upon by the electronic circuits coupled to the reader head.

Title: Cone warping machine control - which utilises electronic calculation for the values for each winding section to give self-correction
Inventor: MAROTZ ERWIN
IPC: D02H3/00
Filed: 1976-09-21
Abstract: In a cone warping machine, the advance of the warps has to be controlled according to the conical angle and the increase of the diameter as the warps are wound round the beam. As the warps are wound continuously, the winding operation is divided into a number of winding sections. While one section is being wound, the amt. of advance for the next phase is calculated electronically from the formula of advance=increase divided by the tangent of the conical angle in the next winding section, before the next section is wound. Process allows a conical warping machine to be operated with minimum supervision as the winding action is self-controlling and continuous.
