Patent GB-2209859-A (GB)
Title: Monitoring of personnel in working environments
Inventor: HALL STEVEN FRANK
IPC: G08B26/00
Filed: 1988-08-12
Abstract: Personnel working in environments in which they may be exposed to health risks are equipped with dosemeters 1 which may incorporate a Geiger counter. The dosemeter is linked by radio with a central remotely located monitoring station 2-5 programmed to interrogate each dosemeter periodically to read the count accumulated over the period between scans, and operate an audio signalling device so that the operative is reassured that monitoring is taking place. After each reading, the monitoring station produces a signal which resets an internal counter of the dosemeter. The central station monitors each operative's dose in terms of dose accumulated and dose rate and at a predetermined threshold level, a signal is transmitted to the relevant dosemeter so the operative can take appropriate action. <IMAGE>
Patent GB-2209620-A (GB)
Title: Compact audio disc autochanger
Inventor: KAWAKAMI HIROSHI
IPC: G11B17/26
Filed: 1988-09-07
Abstract: To select and play one of a number of optical discs carried on trays shelved in a cartridge, a transporting table 501 is elevated to be in register with a shelf and a rack and pinion system (Figs 6 to 8) pulls the tray and disc onto the table, the final part of the drive for this being obtained from a cam wheel 703 which on one side locks a follower into a peripheral circular track to hold the rack and pinion system fully extended while the cam wheel continues to rotate, the other side of the cam wheel 703 having as many contours 720a to 720g as there are cartridge shelves so as to lower the table from the selected shelf onto the playing deck and to raise it back to the shelf for unloading. Connection between the rack and pinion system and a selected disc tray is through a telescopic strut (Figs 11 to 13) that allows for rise and fall of the table 501. A screw drive (Figs 1, 3, 4, 5) positions the transporting table to register with a selected shelf, the table being unlatched from an index member (306) of the screw drive to allow the table to be lowered and raised by the cam wheel, the table latching back to the index member when the table returns to replace the disc in the cartridge.

Title: System for processing line scan video image signal information
Inventor: FUCHS MILAN
IPC: G01N21/89
Filed: 1989-09-21
Abstract: The speed of processing is increased by providing a plurality of image processors 16 each of which processes concurrently a different package of the image signal information derived from the video signal. Each image processor has an input buffer set up to recognise and store only information derived from pixels in a group the numbers of which it has in memory. The signal information supplied to the image processors is simplified by a video signal processor 11 which compares the individual pixel signals in the video signal input with computer-controlled threshold values and outputs to an image information bus only signals representing the occurrences and directions of threshold crossings and the numbers of the pixels concerned. The system is especially for the detection of faults in travelling materials or objects. <IMAGE>

Title: Hazardous emission detection training
Inventor: WARD DAVID ROBERT
IPC: G09B9/00
Filed: 1990-02-27
Abstract: The use of first detection apparatus responsive to a first emission of a hazardous nature (e.g. radio-active or ionising radiations, toxic or nerve gases is taught by training in the use of a second detection apparatus responsive to a second emission of a non-hazardous nature (e.g. a relatively harmless gas). The harmless gas may be given off by a self-contained movable carrier which may comprise activated carbon, or silica gel, or a molecular sieve, and may take the form of a simulated nut or bolt, or a particulate material, or a simulated pebble or stone, or a grease. The gaseous material may comprise ethylene, or butane, or a chlorinated hydrocarbon, e.g. chloroform. A detector of the harmless gas may comprise an explosive atmosphere detector, or a sensitive gas leak detector, or a specific gas monitor, or an electron capture detector and may be calibrated in units of the hazardous emission.

Title: Figurine.
Inventor: CHAN CECIL SHU-ON
IPC: A63H3/00
Filed: 1992-05-29
Abstract: A figurine formed from a gelatinous composition, preferably a melt blend admixture of poly(styrene-ethylene-butylene- styrene) triblock copolymer and plasticising oils has a tacky and soft touch and has a high elongation and tensile strength with excellent shape retention after extreme deformation. The figurine 20 may be formed with an internal cavity 21 with a narrow opening 22 so that the figurine can be turned inside out and remain in a semi-stable form, preferably in the shape of an egg with a hole on top. Downward pressure around the edge of the hole enables the figurine to restore to its original shape giving the illusion of the figurine being hatched from an egg. The figurine may be attached to a wall and as the adhesion fades, it will tumble down the wall. Alternatively two figurines (10, 10', Figs 2 to 5) may be combined by twisting their limbs together and as they untwist themselves, the figurines will move in the manner of wrestlers. <IMAGE>
