Title: A fragmentation body for fragmentation projectiles and warheads
Inventor: NUSSBAUM HELMUT
IPC: F42B12/32
Filed: 1981-11-30
Abstract: A hollow body, for use as a fragmentation case for a warhead or missile, comprises preformed fragments 2, 15 and a cast or moulded matrix. The fragments have basal recesses 4 by means of which the fragments are located in a predetermined pattern upon projections of a mould during casting or moulding of the matrix in a mould cavity.

Title: Gaming machines
IPC: G07F17/34
Filed: 1982-04-01
Abstract: A fruit machine includes a control system 1 which supplies drive signals to a reel mechanism 2 in response to actuation of a game-initiating button 3 to cause the reels bearing fruit and other symbols to be spun and to come to rest with a combination of symbols in a viewing zone. This combination is compared with a list of winning combinations and a prize is awarded in the event of a match. In dependence on the result of the game or on a random basis, a hidden-win detection unit 8 determines whether there is a combination of symbols on the reels along a line which is not visible, or is only partially visible, in the viewing zone which, if within the viewing zone, would constitute a winning combination. If such a combination exists the player may depress a hidden-win button 7 so as to index the reel mechanism 2 to cause the detected combination to appear within the viewing zone, and a prize is then awarded in the usual manner. <IMAGE>

Title: Generating a monitor display cut-out from a matrix of images
Inventor: STICKEL DR ROBERT
IPC: G09G5/34
Filed: 1983-01-31
Abstract: In an apparatus for generating on a monitor display, e.g. for weapon training, a randomly chosen cutout of an overall image stored as an array of images in a mass memory 240, contiguously joined individual images are loaded into a scratch pad memory with fast access, the scratch pad memory 220 consisting of individual video image memories. A laser disc is the mass memory and a process control computer 120, on displacement of the cutout evaluates the direction of displacement and erases certain video images from the scratch pad memory and reloads new ones from the laser disc. Depending upon the direction of displacement, one or a plurality of video images on the scratch pad memory may be involved at reloading. A second embodiment comprises a plurality of mass memories (240, Fig. 2) all storing the same overall array of images: the addressing of said mass memories is then changed according to the direction of displacement of the image cutout. In this embodiment the scratch pad memory is omitted. <IMAGE>

Title: Voice Communication System
Inventor: BRIERLEY WILLIAM EDWARD
IPC: H04B1/46
Filed: 1983-03-12
Abstract: A voice communication system is provided with a voice operated switch 7 which is rendered conductive when a voice signal originating at a microphone 1 or the mouth piece of a telephone is detected by a detector 9. A delay line 8 having a delay of about 5 mS is positioned ahead of the switch 7, to prevent first syllable clipping of a voice signal.

Title: Heat transfer device
Inventor: MOUSLEY JOHN ERNEST
IPC: F24F1/02
Filed: 1983-04-06
Abstract: A heat transfer device 1 for space cooling of the type in which a vaporisable refrigerant is circulated in a closed circuit including an evaporator 3 for collecting heat from air passed over the evaporator thus vaporising the refrigerant, a compressor 4 to compress the vaporised refrigerant and a condenser 5 to dissipate the heat collected to condense the refrigerant. The closed refrigerant circuit is housed in a casing 2 which is positioned in a cold space the air temperature of which is to be controlled and the heat generated during operation of the device 1 is prevented from returning to the cold space by surrounding the condenser 5 with thermally insulating material and positioning the compressor 4 in the air flow path to the evaporator 3. The condenser 5 forms part of a heat exchanger 18 connected to supply and return lines for circulation of a cooling fluid, e.g. water, to which the heat dissipated by the condenser is transferred. The device 1 may form part of a combined space cooling/water heating system in which the heat dissipated by the condenser is utilised to heat the water in a hot water supply. <IMAGE>
