Abstract: The invention relates to apparatus for inserting fibres (6, 6') into helical grooves (7, 7') provided in the surface of a carrier core (8) driven in a longitudinal translation movement. The apparatus includes a support member (3) rotated by a motor (2), feed spools (4, 4') for supplying optical fibres (6, 6') being mounted on said support (3), said carrier core (8) passing through a die (10) which is rotatable in its own plane, said die having a first angular position detector (11) while a second angular position detector (12) is associated with the motor (2), these detectors being connected to a comparator amplifier (13) which is itself connected to a unit (14) for controlling said motor (2). The signals emitted by said detectors are processed by said comparator amplifier (13) which generates an error signal addressed to said unit (14) for controlling the motor (2) so that the rotation of the support (3) is such that each optical fibre (6, 6') is inserted into a groove (7, 7') of the core (8). The invention is used in undersea telecommunications cables. <IMAGE>

Title: Private communication system
Inventor: ANDRICH WOLFGANG
IPC: H04N21/2365
Filed: 1982-09-03
Abstract: From a central station, television picture signals are sent as modulated light, via optical fibres (VLKI...VLKm), to the terminal stations (TInI). The sound portion of television programs, the radio broadcasting sound signals and data signals, after converted to a digital format, are combined by a multiplexor (MUX) to form a time- division multiplex (TDM) signal and transmitted as pulse-modulated light, via an optical fibre (TLK) to such terminal stations. At the terminal stations, the light signals are coupled out, reconverted into electric signals and by them, using a television monitor (VM), television pictures are displayed together with the accompanying sound. The data are displayed on a data display unit (V) and the radio broadcasting programs are reproduced either by the sound section of the monitor (VM) or can be heard via separate earphones (H), or possibly loudspeakers. <IMAGE>

Title: Measuring and recording system for steady-state and transient torques
Inventor: LEUNG WAI SUN
IPC: G01M15/04
Filed: 1982-09-16
Abstract: The system consists of a test bed on which the motor on test is supported by bearings at both ends of its shaft such that the frame (including the stator) of the motor is free of swing. When the motor is energised, its torque, whether stationary or rotational, is transmitted to the frame which tends to swing. The frame is held stationary by a transducer which senses the torque of the motor. The signal of the transducer is fed via an electrical measurement bridge and amplifier(s) to analogue and/or digital voltmeters which are calibrated to measure the torque directly. A tachometer, a variable load, and if necessary a flywheel, are mechanically coupled to the motor. The signal of the tachometer, which senses the speed of the motor, can be fed via amplifier(s) to voltage measuring or recording instruments. When the torque and speed measurements of a motor are taken simultaneously on a cathode ray oscilloscope or an X-Y recorder, the transient torque of the motor from zero speed to full speed can be measured and recorded.

Title: Electro-optical line of sight communications apparatus
Inventor: HAREL ABRAHAM
IPC: H04B10/00
Filed: 1983-04-05
Abstract: A directable optical transmitter 62 formed by an optical fibre is moveable by means of a piezoelectric bending assembly. A receiver 64 receives a light beam transmitted by the transmitter and provides a feedback signal via a wide beam transmitter 74 and receiver 76 to control the direction of the transmitter in dependence upon the accuracy of aim at the receiver. The bending assembly is controlled by a microprocessor, first in a raster pattern search mode. When a signal is first received the raster is stopped and the x, y co-ordinates stored. Bending then takes place one step at a time in an optimising mode and continues until the received signal is a maximum. If the signal should then drop below this level the beam is directed on the stored co-ordinates and the optimising routine is repeated. <IMAGE>
