Title: Control Apparatus for Induction Motors
IPC: H02P1/44
Filed: 1981-07-16
Abstract: Phase of voltage supplied to the induction motor and phase of current flowing in the induction motor are detected and compared with each other. Variable impedance means connected to the induction motor is controlled on the basis of result of the comparison. To this end, the control apparatus for the induction motor comprises variable impedance means (5, 12, 18) connected to the primary or secondary side of the induction motor, first detector means (7, 7') for detecting phase of current flowing in the induction motor, second detector means (8, 8', 8'') for detecting phase of voltage supplied voltage has attained a predetermined value, and phase difference detecting means (9, 9') for detecting through comparison the phase difference between the outputs from the first and the second detector means. When the phase relation detected by the first and the second detector means is reversed, impedance of the variable impedance means is varied under the control of the phase difference detecting means. The apparatus may be used to cut out the auxiliary starting winding of the motor, to short circuit inductances in series with the motor windings, to change between star and delta connections or to control plugging of a 3-phase induction motor. <IMAGE>

Patent GB-2105915-A (GB)
Title: A filter for suppressing or removing harmonic frequencies generated by an output device of a radio frequency source
Inventor: REDFERN JOHN LESLIE
IPC: H03H1/00
Filed: 1981-09-12
Abstract: A filter wherein an inductor L1 and a capacitor C1 receive the signal to be filtered. From the inductor L1, the signal passes along the live plate of a second capacitor C2 to a second inductor L2 laterally displaced from the inductor L1. The signal from L2 similarly passes along the live plate of a capacitor C3 to a third inductor L3 part of which is laterally displaced from L2 and another part of which is at right angles thereto. From the inductor L3 the signal passes to capacitor C4 attached to a transmission line (25) which leads to an antenna (not shown). The signal thus follows a sinuous path and the arrangement of the capacitors allows the inductors to be fitted conveniently into a small housing. Inductance values can be trimmed by adjusting the position of moveable walls (22, 23 and 24). The whole housing 12 can be fitted onto the back of another housing containing the output valve (5, Fig. 3) of the transmitter. The latter housing is usually air cooled and thus the filter can benefit from the same cooling arrangement. <IMAGE>

Title: Metallic cladding of concrete and other structures
Inventor: COUNSELL PATRICK JAMES CLAUDE
IPC: E04C2/26
Filed: 1981-10-01
Abstract: Metallic cladding may be desirable on surfaces of concrete or other structures. A sheet material for effecting such cladding comprises a substrate of fibrous material and/or foamed plastics material with a metallic membrane bonded to one surface and impregnated from its other surface with a cementitious composition reactive with water to form a set mass. The metallic membrane may be a metal foil, for example of copper, or a membrane of non-metallic material such as a silicone rubber composition in which is intimately mixed a proportion of metal powder particles, for example of copper. A structure may be clad by wetting the cementitious composition of the sheet material and applying it to the surface of the structure. A concrete structure with a metallic-clad surface may be produced by lining a mould with the sheet material with the cementitious composition innermost and pouring wet concrete into the mould.

Title: Apparatus for combatting targets
Inventor: SCHUCK WOLF-DIETER
IPC: F41G5/12
Filed: 1982-10-11
Abstract: Apparatus for combatting targets, such as tanks or grounded aircraft, comprise a directable launcher which is coupled with a target location device (9) which controls the alignment movements of the launcher and the triggering of the projectile fired. The target location device (9) has a passive acoustic direction sensor (15) as well as an active acoustic range sensor (17). A common directional microphone arrangement (11) is used for both sensors. As soon as a target is located with the passive direction sensor, the active range sensor (17) is switched on and a short sound impulse is sent out from a sound source (27). The sound reflected by the target is picked up by the microphone arrangement (11) and evaluated in a transit time circuit (29) to determine the range of the target. The launcher is aligned at the target by virtue of the direction signals of the passive direction sensor (15) and the range signals of the active range sensor (17). <IMAGE>

Patent GB-2154787-A (GB)
Title: Laser stabilisation circuit
Inventor: JONES ROGER EDWARD
IPC: H01S5/0687
Filed: 1984-01-17
Abstract: To stabilise the light output from a semiconductor laser (1), that output is split into beams in two optical fibres by a coupler (6). One output beam is the effective output of the laser while the other is a reference output. The reference output is applied via a Fabry Perot fibre optic interferometer (9) to a detector (11) where it is compared with a reference parameter. Any difference results in an error signal which is used to appropriately adjust the laser's current supply to give the light output the required characteristics.   As shown the effective output goes to another Fabry Perot optic interferometer (10) used as a sensor. <IMAGE>

Title: Video noise meter
Inventor: CLEMOW RICHARD DAVID
IPC: H04N17/00
Filed: 1984-03-06
Abstract: In a video signal-to-noise meter for use with a video disc player, the video signals are processed such that the desired vertical insertion test signals (VITS) are picked out from the remaining signal and suitably expanded. Then by operation of the video switch 1, either the video input signal or the expanded VITS signal can be selectively fed to the noise meter in order to obtain the signal-to-noise measurement. Thus, in this first stage the video signal is fed into an analogue-to-digital converter 2 which then passes the signal in digital form to a 1K byte RAM store 3. A Horizontal and Vertical Timing unit 4, which is fed with line select data from a line counter 5, controls the "write" operation of store 3 so that only the desired VITS signals enter it. Likewise, unit 4 controls the "read" operation of store 3 such that its output is a suitable repetition of the stored VITS signal(s) which is then supplied to switch 1 after being put in analogue form by converter 6. <IMAGE>
