Patent GB-2183326-A (GB)
Title: Latent heat thermal storage heaters
Inventor: CROSSLEY PETER WILLIAM
IPC: F28D20/02
Filed: 1986-11-20
Abstract: A storage heater comprises a latent heat store 1, the preferred medium being caustic soda. The store may be surrounded by a fluid 6 which is contained in an outer tank 3 filled to a level 7. Heat is provided by a heating element 2. During heat output the heating element 2 is switched off, the baffles 5 are opened and the fluid 6 rises in natural convection currents, circulating around the divider plates 4 and thus carrying heat away from the heat store 1. During heat input the heating element 2 is turned on and the baffles 5 are closed, resulting in very little heat transfer to the outer tank 3 or the surrounding air. The store may be in direct heat exchange contact with air, either by natural or forced convection. The store may comprise a plurality of separate containers. <IMAGE>

Title: Controlling a heating installation
Inventor: GAYLARD LESLIE RONALD
IPC: F23N1/00
Filed: 1987-04-03
Abstract: Apparatus for controlling a heat generator of a heating installation is provided comprising timer means arranged to provide a heat generating signal to generate heat over a first predetermined time period and a heat suspension signal to substantially stop heat generation for a second predetermined time period. The signals may, for example, control the pump of a central heating installation. The apparatus is arranged to provide the signals alternately during a heating period and the frequency of repetition is sufficiently high that, when used to control a central heating installation for a building, a substantially constant temperature of heating is obtained. The lengths of first and/or second time periods may lie within the range 1 to 30 minutes each. In an embodiment of the invention, two frequency selection devices (5, 6) are provided for controlling the frequency of operation of a pulse generator (1). The pulse generator is connected to a pulse counter (2) and means (3) are provided, responsive to the pulse counter, for controlling the frequency selection devices whenever the pulse counter counts a predetermined number of pulses from the pulse generator.

Title: Nutcracker with controllable force
Inventor: DAVEL PETER ERNEST
IPC: A47J43/26
Filed: 1987-06-04
Abstract: In a manually operated nutcracker in which the nut is held within a cylindrical nut holder 12 force is applied against the nut shell by pumping a spring-loaded pivotal handle 1 acting on a movable cracker jaw 11 within the cylindrical nut holder. A trigger device 7 locks the cracker jaw against backward movement between strokes (pumps). The step wise movement of the cracker jaw within the cylindrical holder permits sensitive control of the force applied to the nut shell.

Title: Multi-stage parallel binary adders and/or subtractors
Inventor: ROBERTSON IAIN CRAIG
IPC: G06F7/50
Filed: 1988-02-25
Abstract: A multi-stage parallel binary adder and/or subtractor has a plurality of stages 0-31 divided into a plurality of groups p1-p16 of consecutive stages. Each group of stages can produce a carry propagate signal and/or carry generate signal respectively for controlling a series-connected MOS transistor and a shunt-connected MOS transistor along a carry path. A carry break signal produced by NAND gates M1, M2 ---, selectively disconnects the carry propagate signal(s) from the series-connected transistor(s) and blocks the conduction of the shunt connected transistor to separate the carry output from one group of stages from the carry path of the next group. The stages may form a single adder/subtractor, or may be divided into independent equal groups of 2, 4, 8, or 16 stages, depending on selection signals J, K1-K4. <IMAGE>
Patent GB-2204764-A (GB)
Title: Time division multiplex data system
Inventor: FERGUSON STEPHEN PATRICK
IPC: H04J3/16
Filed: 1988-04-20
Abstract: A Multiplexer contains means for detecting whether an incoming data stream is synchronous or plesiochronous and for controlling the digital switch of the multiplexer in response to the detecting means so that on detection of synchronous traffic successive bytes of traffic are switched to different tributaries and on reception of plesiochronous traffic successive bytes are periodically switched to the same tributary. For plesiochronous traffic, sub-frame capacity is reduced to 60 channels each sending 32 bytes in 30 sub-frames, the remaining 2-subframes being then available for justification overheads. To effect this, each channel sends two bytes in two of the 30 sub-frames and one in each of the other 28. <IMAGE>

Patent GB-2236450-A (GB)
Title: Method and apparatus for dithering graphic images
Inventor: CARRIE SUSAN
IPC: H04N1/41
Filed: 1990-05-08
Abstract: In the method and apparatus of the present invention, the distance between the intensity value of the base value (that is, the closest quantized intensity value less than the input intensity value) and the input intensity value is adjusted according to a mapping function between the size of the interval between the intensity values of the base value and the base value +1 (i.e., the next large quantized intensity value) and the range of values in the dither matrix. By adjusting the distance between the base value and the input intensity value, the correct proportion of base values and base values +1 is maintained regardless of the difference in size of the interval and the range of the dither matrix, thereby insuring that the intermediate intensity values between quantized values are accurately simulated. In one embodiment of the present invention, the range of input intensity values is mapped to the full range of quantized intensity values by mapping the minimum and maximum input intensity values respectively to the minimum and maximum quantized intensity values and evenly distributing the remaining input intensity values between the minimum and maximum quantized intensity values. A second mapping function is then generated between the size of the interval and the size of the dither matrix to adjust the distance values and insure the accurate simulation of intermediate intensity values. In the resulting output, the accumulated error is reduced and the error is evenly balanced and distributed such that the image energy, and therefore the image brightness, is conserved. <IMAGE>

Title: Treatment of video signals produced by aperture correctors
Inventor: OSBORNE TREVOR MALCOLM
IPC: H04N5/208
Filed: 1991-03-20
Abstract: To reduce artefacts in signals produced by aperture correctors a limiting signal C' is formed which clips the correction signal at a given amplitude (Fig 2 (iii)). The limiting signal is derived from a user input which, after processing in a polarity selector 11 is subtracted from the correction signal by subtractor 10. The output of the subtractor is clipped 12 to eliminate any part of the signal which has crossed the zero axis and the clipped signal, which is the limiting signal, is subtracted from the correction signal in subtractor 14. <IMAGE>
