Patent GB-2059569-A (GB)
Title: Improvements in and relating to cooling apparatus
IPC: H01L23/467
Filed: 1979-09-12
Abstract: A heat sink and cooler for a portable radio transmitter comprises an aluminium casing 5 whose interior is split up into water compartments 18, 20, 22 and 24, in communication with each other, and an air compartment 26 which is sealed from the water compartments. The electrical or electronic components 6 are mounted on the outside of the casing 5 and they and the casing are mounted inside a thermally insulated outer case 32. Heat produced by the components 6 is dissipated in the water. The water is cooled by passing air through the compartment 26. The air flow may be switched on intermittently, for example when the transmitter is not operating, so as to remove heat previously stored in the water during a cycle of operation of the transmitter. Instead, the air flow can be on continuously while the transmitter is operating. <IMAGE>

Title: Bale accumulators
IPC: A01D85/00
Filed: 1979-10-02
Abstract: A diverter 11 diverts successive bales alternately to compartments 5, 6 and 7, 8 at opposite sides of an accumulator 1. A passing bale engages an actuating arm 13, which actuates the diverter 11 by an indirect and/or intermittent drive connection. For example, a first gear 21 pivots with the actuating arm 13, and engages a second gear 18 for only a portion of its travel. The gear 18 operates an overcentre spring 19, which in turn operates to urge the diverter 11 to pivot between end positions. A second overcentre spring 22 operates to bias the actuating arm 13 into an end position. Because of the nature of the drive connection between the actuating arm 13 and diverter 11, the accumulator is especially adept in accommodating irregularly delivered bales. It is suitable for forming, inter alia, bales in flat-eight array. <IMAGE>

Title: Camera exposure control circuit
IPC: G03B7/081
Filed: 1979-11-09
Abstract: Upon shutter release:   (a) brightness measured at 2 with the diaphragm 1 fully open is stored at 5 to calculate shutter time (b) the diaphragm stops down to a manually pre-set value, but is halted before reaching that value if the detected brightness falls below a certain value (set in at 4). Preferably if the diaphragm does reach its pre-set value, the shutter time is automatically re-adjusted to take account of any difference between the actual and pre-set diaphragm values. If the diaphragm is halted before reaching its pre-set value, no adjustment of shutter time is made.   In this manner the exposure setting errors arising in the case of lower illuminances on the photo-conductive cell 2 are eliminated and the measurement range of the camera is increased. <IMAGE>

Title: Engine Speed Measuring System
IPC: G01P3/64
Filed: 1980-06-09
Abstract: This disclosure relates to a system for measuring the instantaneous speed of an index point on a rotating part. The part may be a toothed gear 63 or a wheel of an engine 10, and the index point may be an identifiable point on the part. The system comprises a sensor 61 that is mounted adjacent the part, the sensor including two sensing elements 71, 72 that are spaced apart in the direction of movement of the point as the part rotates. As the point passes the sensor, it causes a first pulse to be produced by one element 71 and then a second pulse to be produced by the other element 72. The system further includes circuitry 22 that responds to the two time-spaced pulses and produces an indication of the time interval between the two pulses. This time interval is a function of the speed of the point which in turn is proportional to the rate of rotation of the part. In the instance where the part is attached to an engine flywheel, the time interval is also an inverse function of engine RPM. <IMAGE>

Title: Incandescent and fluorescent caplight device
IPC: F21L14/02
Filed: 1982-04-26
Abstract: An illuminating device for affixing to a miner's cap is provided with an incandescent bulb and a fluorescent bulb within a housing with selective energization of either the incandescent bulb 20 or the fluorescent bulb 32. A quartz/halogen incandescent bulb 20 provides a higher intensity spot beam and the fluorescent bulb 32 provides a wider and more peripheral lighting as is desired for close work. The light shines through a clear, plastic lens 24 which may be broken and, if it is broken, the high intensity incandescent bulb is shifted to open the electrical circuit for the incandescent bulb 20. Preferably, the incandescent bulb 20 is spaced from the lens 24 by a spacing means 30 in the form of a transparent tube 33 which holds the bulb 20 against the biasing force of a spring ejector mechanism. When the lens 24 is broken, the spacer tube 33 falls allowing the ejector mechanism to shift the incandescent bulb 20 to a position opening its electrical circuit. <IMAGE>

Title: Metal-insulator-semiconductor devices
Inventor: WHITE ANTHONY MICHAEL
IPC: H01L21/34
Filed: 1982-06-16
Abstract: The insulator under the gate (12) of an MIS device is formed as a double layer (4, 5); the first layer (4, 18) next to the substrate, is thin, e.g. less than 250 ANGSTROM , whilst the second layer (5, 19) is thicker, e.g. more than 350 ANGSTROM  thick, one layer is accumulating whilst the other is depleting. Whether accumulation, depletion or inversion occurs at the substrate insulator interface is controlled by the thickness of the first layer (4, 18), which therefore also controls the gate voltage and sign at which the device turns between on and off. The device utilizes quantum mechanical effects. Substrate materials include CDxHg1-xTe, Si, InP, GaAs, GaAlAs. The first layer (4, 18) may be of anodic oxide. The second layer (5, 19) may be ZnS. Field effect transducers and charge coupled devices may be made incorporating the double layer gate insulator. <IMAGE>
