Patent GB-2042288-A (GB)
Title: Controllable rectifier circuit including turn-off arrangement
IPC: H03K17/73
Filed: 1980-01-21
Abstract: When the forward load current through a thyristor is commutated it does not immediately recover its availability to block forward current flow due to re-applied forward voltage, the time taken for this blocking ability to return is known as the thyristor turn-off time. Hitherto a low-valued current has been passed through the thyristor immediately after commutation in the reverse direction to achieve reduction of the turn-off time. The present invention operates to achieve a greater reduction of the turn-off time by passing a low-valued current through the thyristor in a forward direction immediately after commutation. Several alternative circuit arrangements and operating configurations for supplying the forward recovery current are described.

Title: Coin-operated gaming or amusement machine
Inventor: WATTS RONALD ARTHUR
IPC: G07F17/34
Filed: 1981-08-11
Abstract: A fruit machine has a video display simulating mechanical reels. The number of symbols visible on each reel is usually constant for the normal reel spin, but when an adjustment feature such as nudging is available the "windows" may enlarge above and below their normal extent to show more symbols. Thus a player can better judge how to adjust the reels. As the reels are adjusted, the windows may close up again, or cease to display symbols in the vacated positions, in order not to reveal too much of the symbol pattern. <IMAGE>
Patent GB-2082340-A (GB)
Title: Production of Photographic Masked Colour Images
IPC: G03C7/18
Filed: 1981-08-13
Abstract: Masks for photographic dye images have been described which improve colour quality or correct tone reproduction. They are of opposite sign to the image being reproduced or printed, and preferably deliberately made unsharp. According to the invention there is provided a method of producing a photographic dye image masked by an unsharp masking dye image in a mask layer characterised in that the unsharpness of the masking dye image is obtained by causing the masking dye to diffuse over a distance into the mask layer from another layer. The photographic dye image and the masking dye image are preferably produced concomitantly. In an example, a redox dye releaser associated with an imagewise exposed negative working silver halide emulsion on development releases a diffusible dye in the light-struck areas which diffuses over a distance into the mask layer forming a masking dye image for the retained dye image. A masked positive transparency can be produced in this way.

Title: Disc spring clip
IPC: F16B21/20
Filed: 1981-08-28
Abstract: A disc spring clip, for use in securing a shaft in a bore or a wheel on a shaft, e.g. for retaining a handwheel on the shaft of a vehicle seat-reclining mechanism, has a central aperture (2) defined by four equally-spaced teeth (3) directed inwardly of the disc. The innermost edges (4) of the teeth are spaced from the plane of the periphery of the disc and are preferably arranged helically so as to permit the clip to be screwed off the shaft. This may be accomplished by a suitable tool having pegs engaging in holes (5) in the disc. The disc may thus be pushed on to the shaft for ease of installation of a seat- reclining mechanism, but may be screwed off, e.g. for repair or maintenance of the mechanism. <IMAGE>

Title: Apparatus for transferring data between relatively rotating members
Inventor: COLLIER MARTIN JOHN
IPC: H04B10/00
Filed: 1981-10-14
Abstract: When data is transmitted between relatively rotating members in the form of electrical signals, this can be done using slip ring contacts. If, however, the information is required to be transmitted in optical form conventional slip rings obviously cannot be used. The problem is particularly acute when the information is to be transmitted along more than one optical line which would become twisted. Figure 2 shows a multiplexer (6) which multiplexes data from a number of inputs (5), each carrying light of different wavelengths  lambda 1,  lambda 2,  lambda 3,  lambda 4, onto a common optical line (7). This passes from one member (1) to another member (2) via a rotary joint (8) on the axis of rotation (X). The data is then demultiplexed by a demultiplexer (9) onto optical fibre outputs (10) which correspond to the inputs to the multiplexer (6) and carries the same wavelength  lambda 1,  lambda 2,  lambda 3,  lambda 4 as the inputs. Thuds by multiplexing the data only one line need be used and the rotary joint prevents the one becoming twisted. <IMAGE>

The image memory (4) may store one page of data and may be linked with a disc store (5) for storage of more pages of data. These may be printed serially on the same sheet. Also disclosed is apparatus for refeeding a printing sheet so that it is printed on both sides, and for controlling the position of the sheet to select the reproduced image position. <IMAGE>

Title: Heat exchanger having a bundle of parallel tubes and method of assembling its component parts
Inventor: CADARS PATRICK
IPC: F28F9/16
Filed: 1982-09-09
Abstract: The heat exchanger (10), e.g. a motor vehicle radiator, has a bundle of thin-walled metal tubes (12) passing through a perforated plate or collector (18) via holes (23) therethrough. The collector plate is made with holes having walls that are highly elastic, either by the collector being molded from a highly elastic plastic, or by the collector plate being made from a sheet of metal with the holes being formed with spring shaped rims. The elasticity is used to grip and seal the tubes (12) in the holes (23) through the collector plate, and the relative strengths of the tubes and the plate are such that the portions (38, 61, 92) of the tubes thus elastically gripped in said holes are contracted by the elastic grip and are flanked on either side by non-contracted portions (42, 41; 66, 74; 93, 94) of tube which ensure that the tubes are held fast against longitudinal movement in either direction relative to the collector plate.
