Title: Limiting the Variation in Gassing Current in Batteries
IPC: H02J7/14
Filed: 1981-10-30
Abstract: A regulator (1) for a three-phase generator (2) in a motor vehicle or the like effects temperature-dependent limitation of the variation of the gassing current of a starter battery (B) dependent upon age and variations in operating characteristics. The battery charging current and the battery voltage (UB) are measured by means of a measuring shunt RSh in the connection lead (5) between the generator (2) and the battery (B) and are utilised by the regulator, such that high gassing currents are reduced and low gassing currents are increased by varying the output voltage (UG) of the generator. A sensor (8) responds to battery temperature and a temperature-dependent desired voltage of the battery is combined with the adjusting voltage from the battery voltage and charging current in a Schmitt trigger which controls the generator field current. The regulator de-energizes the three-phase generator in the event of overvoltage as sensed at the output D+ used also as a source for the generator field current. <IMAGE>

Title: Game-playing machines
IPC: G07F17/32
Filed: 1982-04-01
Abstract: A fruit machine comprises a control system 1 which supplies drive signals to a reel mechanism 2 in response to actuation of a game-initiating button 3 to cause the reels bearing fruit and other symbols to be spun and to come to rest with a combination of symbols in a viewing zone. If this combination is one of a number of possible winning combinations a prize may be awarded by a pay-out control 5 or alternatively a guaranteed-win feature may be made available to the player by a game- feature processor 6. This enables the player to gamble for a win of a higher value by depressing a guaranteed-win button 7. Depression of the button 7 causes a guaranteed-win selector 8 to select one of the possible winning combinations, and the control system 1 then causes the reels to be respun and to come to rest with the selected winning combination in the viewing zone. A prize, which may or may not higher than the prize which would otherwise have been obtained, is then awarded by the pay-out control 5. <IMAGE>

Title: Electronic augmentation of radar techniques
Inventor: MITCHELL RICHARD LEE
IPC: G01S7/38
Filed: 1983-01-24
Abstract: Apparatus and methods are disclosed in which a radar target can be electronically disguised to appear like another target. The technique is based on the generation of a desired synthetic target signature that is superimposed on the normal radar echo for the moving simulation platform. The simulation system consists of multiple antennae with tapped delay lines and signal modulators to provide the means of generating the desired target signal that is extended in angle and range. It is possible to utilize very realistic models of the desired target; the necessary information can be collected on a high-resolution measurement range. The general technique works against any pulsed radar in a monostatic geometry. A modified technique for operation against continued wave and bistatic radars is also discussed. The applications of the technique include the testing of missileborne guidance radars against cooperative targets and electronic countermeasures (ECM) applied to a target vehicle to deceive the radar. In either case, the physical target will be electronically augmented so that it appears like an entirely different target to the radar. <IMAGE>

Patent GB-2165062-A (GB)
Title: Optically controlled actuator
Inventor: WEBB DAVID JOHN
IPC: F15C1/04
Filed: 1984-09-28
Abstract: Compressed air to a pneumatic actuator 8 is supplied through a control device 1 having an air inlet 3 an air outlet 4 and a vent 5. Normally a smooth lamina flow stream passes between the inlet 3 and the outlet 4 and relatively little air is lost through the vent 5. The flow can be interrupted by supplying pulses of light from a source 9 along an optical fibre 11 and into the control device 1 where it strikes an absorber 6 producing acoustic energy which generates turbulence in the flow stream causing the compressed air to be vented at 5. The resulting reduction in pressure at the outlet 4 causes the pneumatic actuator 8 to produce some mechanical control function. In an alternative arrangement (not shown) the light falls on a flexible beam within the control device 1 and the resulting heating effect on the beam causes the latter to bend into the flow stream producing a similar effect. <IMAGE>
