Title: Telephone for the disabled
Inventor: WEALTHY PETER BROADBENT
IPC: H04M1/72502
Filed: 1991-05-30
Abstract: A telephone for the disabled has a Dodecahedron body 1 which has twelve pressure sensitive switches 2, one on each face of the body. The method of dialling would be to roll the body with the foot until the digit required was upwardly facing and then apply firm downward pressure to the upwardly facing pressure sensitive switch. The body would then be rolled to the next digit required and the same process repeated. This procedure would then be repeated until the whole number required had been dialled. <IMAGE>

Title: An apparatus for the control of an access to a video memory
Inventor: YAMAMURA KIMIO
IPC: G09G5/391
Filed: 1991-09-02
Abstract: Apparatus for the control of access to a video memory 7 comprises a memory width register (in control unit 20) storing display dot width data (in bits 0 and 1). Access timing is determined by this data, to allow for different display resolutions. Therefore, access timing is easily controlled, dependent on the memory speed of the video memory and resolutions by merely changing said content of the memory width register. When the video memory 7 is accessed (CPU -> VRAM) during a display cycle of the video memory, video data may be stored (WAIT) in a buffer memory 22, and transferred (VRAM WR or VRAM RD) from the buffer memory after the display cycle is finished. <IMAGE>

Patent GB-2252163-A (GB)
Title: Temperature sensing apparatus
Inventor: MELTON DAVID LAURENCE
IPC: A62C37/48
Filed: 1991-12-10
Abstract: In order to sense the reaching of a predetermined temperature level, a gaseous medium which has a critical temperature coinciding with the predetermined temperature is contained within an enclosure (16). A pressure responsive component (22) is in communication with the enclosure. When the predetermined temperature is reached, the gaseous medium will expand explosively because it has reached its critical temperature and will burst the enclosure. The pressure responsive component will sense the sudden drop of pressure and will produce a signal or operate some other mechanism in response to the attainment of the predetermined temperature. The component (22) may be a valve or a cylinder (12) supplying gas to a vessel (10) or an actuator which closes louvres in an air conditioning duct. Pressure may be sensed by a bellows or a diaphragm; the latter may retain a weighted lever until pressure is lost. <IMAGE>

Title: Liquid transfer device
Inventor: BUNCE ROGER ABRAHAM
IPC: B01L3/00
Filed: 1994-11-25
Abstract: The device comprises first and second capillary flow channels (210, 212) in abutment over an interface region (218), the first channel having a capillarity which is higher than that of the second channel.   Typically, the first channel (210) defines a volume definition zone for a first liquid (223) in fluid connection with the second channel (212) and means (219) for receiving excess first liquid, wherein the second channel is arranged for application of a second liquid (236). The first liquid may be blood plasma, and the second liquid diluent. The device allows the application of sample in excess, application of diluent liquid leading to reaction of assay reagents (228, 230) with sample in the volume definition zone only. A third channel (214) of lower capillarity than that of the first channel (210) may provide means by which liquid is introduced to the first channel, and/or means for receiving excess first liquid. The difference in capillarity between the channels may arise from differing pore sizes and/or wetting characteristics or compression of material. Utility is in diagnostic assays. <IMAGE>
