Title: Cable winding machine - has proximity switches to register material on spools to control rotary twisting speeds
IPC: D07B3/06
Filed: 1978-07-19
Abstract: The speed control on the rotating parts is determined according to the quantity of material present on the unwinding spools. The system ensures that the twisting machine capacity is used to the full, without incurring a moving mass level which could cause damage. The rotary drive speed is increased so that the unwinding spools maintain a constant centrifugal force effect. The operating rotary speed is programme controlled, and there is a sensor to register the amt. of material on the spools. The sensor registers the max. amt. of material on a spool on each spool carrier unit. There is a sensor circuit for the sensors of several spool carrier units, so that the spool with the max. material on it can be selected as the datum point for the rotary speed control unit.

Title: Electromagnetic relay operation direction indicator - has arrow or flag on or over armature to indicate movement direction when energised or de-energised
Inventor: BRANDT MANFRED
IPC: H01H50/08
Filed: 1978-11-03
Abstract: Electromagnetic relay has a flag or compass needle type indicator on the armature to indicate the direction of movement. The armature also operates the spring sets and so the indicator shows which spring sets are operated. The indicators may be either clipped to the relay armatures or clipped over the realy dust cover. They are intended for relays which move a horizontal armature upwards when energised. One alternative is a flat (132) on a bar (131) across the armature (13, 14, 15, 16) which moves the spring sets. When the relay is energised the flag will flip over to pointup ards as the armature moves. The indicators show where the relay armatures should be when several relays are arranged together in equipment, e.g. relays (13, 15) which are energised and where the armatures have moved up show the flag up (132, 152) and have moved (bars 131, 151 up).

Title: Scanning oscillator system for GHZ range - has two mixers with phase locking oscillator and corrective control signal oscillator at their inputs
Inventor: HAMMERSCHMID WALTER
IPC: H03L7/20
Filed: 1978-12-22
Abstract: The sweep oscillator has a reference signal oscillator and a main oscillator with adjustable frequency via a phase loop. A first mixer (AM1) acts as phase comparator in a phase locked loop, and a second mixer (AM2) is used for any frequency tubing. Both mixers treat a voltage controlled oscillator (HO) output with two different frequencies (F1, F2) derived from two different sources (O1, O2). A correction signal (S3) is added (S) to the control signal from the first mixer applied to the VCO control input. The correction signal is derived from the second mixer output, describing the frequency differences, using logic (AL) coupled to the channel and a waveband selecting unit (EV). The latter is preferably switchable to deal with two, or more, frequency timing ranges.
