Title: Television receivers for time division multiplexed signals
Inventor: MURRAY BRUCE
IPC: H04N9/64
Filed: 1983-02-14
Abstract: In a television receiver for signals according to the C-MAC system where the chrominance and luminance signals are compressed and transmitted sequentially during television line periods, the demodulated analogue signal is applied to an analogue-to-digital converter 9. The zero level of chrominance reference is extracted by a clamp circuit 10 whilst the black level reference is extracted by a further clamp circuit 13. These reference levels are applied to a difference circuit 18 and the resulting difference subjected to amplification in an amplifier 19. The output of amplifier 19 is applied to the reference input of the converter 9. In the received signal the chrominance component has a larger maximum amplitude than that of the luminance component. To enable the converter 9 to produce digital signals proportional to content rather than absolute value the amplifier 19 is arranged to change its gain such that its output is greater during periods containing the chrominance component than during periods containing the luminance component. <IMAGE>

Title: The production of thin marble sheets
Inventor: PATCHAKAPATI MANAROJ
IPC: B28D1/04
Filed: 1984-07-16
Abstract: Thinner marble sheets are produced by making a first cut from one longitudinal side edge of an intermediate size sheet and a second cut from the opposite side edge. The results should be to approximately the longitudinal centre line of the intermediate sheet. If the two cuts intersect then a spacer can be fitted in the region of the first cut to hold the final two sheets apart to prevent the cutting blade being trapped during the second cut. If the two cuts do not intersect then a small longitudinal column of marble is left which can be fractured after compression of the two cuts by simply pressing together one side edge of the cut sheet. Preferably, the first and second cuts are made with the intermediate sheet in a horizontal orientation.

Filed: 1984-12-21
Abstract: A plurality of infra-red detector elements D1-DNx are, in a simplest case, arranged in two parallel lines I and II with the elements of one line shifted with respect to the elements of the other line by a distance  DELTA xs in the direction of the lines. Each line has DNx, individual elements. Signals from the detector lines are processed in delay and interlacing devices. The length of each line corresponds to a complete horizontal field of vision spanning 2Nx columns of the imaged scene. This field of vision is scanned vertically by a mirror sweeping over the fixed detector array during a TV field duration, an object line raster being produced by each line after optoelectronic conversion of the incident radiation. These object line rasters are interlaced by means of the delay and interlacing devices to produce, on a TV monitor, a video signal which can be represented without interposition of a standard converter and which is free from aliasing effects. <IMAGE>

Patent GB-2180452-A (GB)
Title: A sterilising vessel
Inventor: BRADFORD WILLIAM DEREK
IPC: A61L2/07
Filed: 1986-09-16
Abstract: A sterilising vessel has a container (20) in which the objects to be sterilised are placed. The container is placed inside a pressure-tight jacket (10) which contains a small volume of water (18). The water is heated until it boils, and the resulting steam passes up a gap between the jacket and the container and then into the container from above. The steam then displaces the air which initially is present inside the vessel downwardly through a valve (28) and this valve is arranged so that it closes once all the air has been displaced and steam starts to be vented. Because the exit opening from the container for the air or the steam is at the lower part of the container, one can be sure that all the air has been displaced from the container once steam starts to pass through the valve (28). <IMAGE>
