Patent GB-2152160-A (GB)
Title: Ratchet clutch
Inventor: SCHWERDHOFER HANS JOACHIM
IPC: F16D41/30
Filed: 1984-12-19
Abstract: The ratchet clutch comprises at least two pivotably mounted pawls 33,35 offset in angle in relation to one another about the rotation axis. The pawls are resiliently initially stressed in the direction of engagement with teeth 13. The angular intervals of the pawls 33 and 35 are made unequal to an integral multiple of the angular interval of the teeth of the ratchet toothing. In this way even when the ratchet toothing has a small number of teeth the idle motion of the ratchet freewheel in the transition from the freewheeling function to the driving function can be kept slight. <IMAGE>

Patent GB-2234392-A (GB)
Title: Switch and power limiter device
Inventor: KRUMM CHARLES F
IPC: H01L21/263
Filed: 1985-05-15
Abstract: The device for use in microwave application is made with conventional FET processing technology, a current conducting layer (14) being formed at a surface of a substrate (12), the device then being electrically isolated by using any one of a number of conventional processes. Ohmic contacts (16, 18) are deposited to make electrical contact at the conducting layer. A groove (20) is then cut with a focused ion beam across the conducting layer and between the ohmic contacts. The length ( alpha ) of the groove controls the threshold voltage for the device and the depth (d) controls the saturation current. Very low values of saturation current can be obtained by controlling the groove dimensions thus significantly reducing the DC power drain when the device is operated just above saturation. A very high differential resistance ratio is obtained by adjusting the threshold voltage of the device. <IMAGE>

Title: Switches
Inventor: FU CHI-CHIEH
IPC: G04C23/22
Filed: 1986-04-11
Abstract: A switch comprises a motor 3 for driving minute and hour hands, a set of cams 5 movable with the minute hand for repeatedly opening and closing contact sets and a slotted wheel 4 movable with the hour hand for sequentially connecting the contact stets in circuit. A one hour time cycle is obtained by connecting one of the contact sets in circuit with an output socket 9 by a switch 8 and by turning a selector 6 from the position shown to its other position in circuit with the switch 8. The on and off times the power supplied to the output 9 during each hour of operation will then be determined by the shape of the cam 5 controlling the selected contact set. To provide a 12 hour time cycle, the selector 6 is turned to the position shown to cause a mmber movable in the slot in the wheel 4 to be connected in circuit with each of the conrtact sets in turn in a sequence determined by the shape of the slot. <IMAGE>

Title: Video special effects system with luminance modification
Inventor: KAWABE SHIGEHISA
IPC: H04N5/265
Filed: 1988-11-07
Abstract: A special effect system for a television video signal has an A/D converter 2 for obtaining a digital video signal from an analog video signal, a video memory 4 for storing the digital video signal, a write address generator 3 for generating write addresses determining the locations in the video memory at which the digital video is written, a read address generator 5 for generating read addresses to read out the stored digital video signal from the video memory 4, and a D/A converter 7 for converting the digital video signal read out of the video memory into an analog video signal. A luminance modifying circuit 12 is coupled between the video memory 4 and the D/A converter 7 for modifying a luminance level of the digital video signal read out. The read address generator 5 includes a distance calculator 24 for calculating the distance between the position of each picture element of a video image and a predetermined straight line in the field of the video image. A first function generator (25, 26) is responsive to the calculated distance to generate a first function by transforming the calculated distance to produce a read address, and a second function generator (13, 14) is responsive to the calculated distance for generating a second function by transforming said distance to produce a control signal supplied to the luminance modifying circuit to modify the luminance level of the digital video signal in accordance with the control signal. The luminance level is thereby modified to create an illusion of three dimensions in the geometrically transformation effected by the first function generator (25, 26). The system may be used to produce a three dimensional "page-turning" effect, in which the brightness of pixels near the "highest" portion of the turn (lying on a straight line) is increased most. …<IMAGE>…

IPC: B60H1/00
Filed: 1990-03-24
Abstract: A compact, exhaust gas driven air cycle air conditioning system comprising an expansion turbine (18), two compressors (12, 14), two heat exchangers (16, 20) and an exhaust turbine (38) is preferably controlled by means of an exhaust gas bypass arrangement (44, 46, 48) and supplies either hot or cold conditioned air, as required, to a load air space (26). Switching between cooling and heating modes is implemented using two-way valves (28, 30) such that the same components may be used, and in all embodiments the conditioning air is supplied from a dry, closed loop. In reverse flow embodiments the working air enters the turbine first. In all embodiments moisture removal devices (22, 32, 62) are incorporated to avoid heat exchanger icing and also control humidity. In addition, de-icing systems may be included for use in those applications where heat exchanger icing is a particular problem. Further embodiments allow control over the temperature at which air is delivered to the load by diverting controlled amounts of hot or cold air, as appropriate, to be mixed with the conditioning air. An extra compressor may be driven by a high speed motor as an additional means of power input under conditions of low exhaust gas energy. <IMAGE>
