Patent GB-2275540-A (GB)
Title: Gas leak sensor system
Inventor: RIDENOUR RALPH GAYLORD
IPC: G01M3/04
Filed: 1993-08-25
Abstract: A gas leak sensor system detects the presence of gas leaking into any one of a plurality of test spaces (11 - 16), for example, refrigeration gas into a refrigeration case. A plurality of tubes (18) extend from each of the test spaces to a sensor location whereat a selector valve (26) is connected to each tube. A controller (22) actuates the selector valves to select tubes in a particular order and a vacuum source (30) draws air and any leaking gas through a selected tube and through a gas sensor (19) to activate an alarm (20). The gas sensor is purged at least each time a leaking gas has been sensed. <IMAGE>

Title: Liner for dispensing container
Inventor: WINER ROBERT
IPC: B65D83/00
Filed: 1994-08-03
Abstract: Liner (14) for a dispensing container, especially a self-pressurized container of the non-aerosol type with a liner type sleeve assembly comprising the liner inside an essentially cylindrical elastomeric sleeve. The liner is generally cylindrical, having a sidewall (34) extending from an open end to a closed end, and a tip (36) at the closed end, and comprising a regularly convoluted portion comprising longitudinally extending convolutions (48) which extend from the upper sidewall toward the closed end and terminate at the tip (36). These convolutions (48) or pleats are formed by alternating longitudinally extending peaks (50) and valleys (52). The convoluted mid section (34) of the liner is both radially expandable and flexible, but the entire liner is stiff enough to retain its shape in the unstressed state. The liner has memory so that it returns to its unstressed shape, when stress is removed. The average sidewall thickness at any cross-section along the length of the liner is about 0.010 inch to about 0.020 inch, and the wall thickness in the axial direction at the tip is about 0.1 inch to about 0.3 inch. <IMAGE>

Title: Saw filter
Inventor: KONDRATYEV SERGEI N
IPC: H03H9/64
Filed: 1994-09-21
Abstract: The filter has an even number of tracks 10, 11, each track comprising reflective input and output IDTs 4, 5, 6, 7 having a partially reflecting grating 8, 9 disposed between them. One of the IDTs 5 of each pair of tracks has its electrodes connected in opposite polarity to those of the other IDTs of the pair of tracks and the separation of the input and output IDTs of respective tracks of each pair of tracks is substantially the same. The relative dispositions of the partially reflecting gratings are such that waves launched into respective tracks of a pair of tracks undergo at least one reflection from the partially reflecting grating prior to being coherently incident on the output IDTs. By virtue of the oppositely connected electrodes of one of the IDTs, direct coupling through the tracks is inhibited at substantially all frequencies. <IMAGE>

Title: Two-handled lifting device
Inventor: HART DOUGLAS
IPC: B65G7/12
Filed: 1995-09-22
Abstract: A lifting device comprises a hollow elongate centre-section with two slightly larger hollow elongate sections telescoping from it at either end. Flat plates pivot from the free ends of the larger sections and extend downwards from them and act to clamp two sides of an object to be lifted. Handles are fixed to these plates and extend above and substantially parallel to the elongate members. The separation of the plates can be fixed by pins which engage with co-operating holes in the small and larger sections.

Title: Magnetic bingo board
Inventor: ITKIS YURI
IPC: A63F3/00
Filed: 1995-10-03
Abstract: A transparent bingo card 2 overlays a magnetic indicator board 1. The bingo numbers on the card are marked with a magnetic wand 3 that darkens the area of the magnetic indicator board immediately underneath the bingo number. All marks are erased at the start of new bingo game by an eraser magnet 9 sliding inside of the indicator board. The indicator board incorporates a microprocessor that optically tracks all cards being played by reading data marks on the transparent bingo board. A point of sales terminal, in which game card identification number, credit authorisation and end of accounting period are input, enables usage of a game card to be accounted. The darkening of the magnetic indicator board may be caused by the upward movement of magnetic particles (Figure 6) or a magnetic, hollow body (55, Figure 22), or by the rotation of a suitably coloured indicator magnet (61, Figure 24), these movements being magnetically induced. The magnetic particles may be free-floating in air, or suspended in a liquid of appropriate viscosity.

Title: A compact cam drive assembly for moving a lens of an electrophotographic apparatus
Inventor: MEIJER WIL
IPC: F16H25/14
Filed: 1997-02-28
Abstract: A cam drive assembly comprises at least two cam surfaces 42, 44 rotational driven by motor 49 via gear 48. As cams 42, 44 rotate they cooperate with cam follower 50, thereby causing lever 54 to pivot, either towards or away from the rotational axis of cams 42, 44, about shaft 56. Cam follower 50 is connected to a spring 66 via first wire 60 and pulley 64 which is in engagement with second pulley 76. As the lever 54 pivots the first wire 60 is drawn through pulley 64 causing it to rotate, this rotation is transmitted to the second pulley 76 thereby moving second wire 70. Both ends 72, 74 of second wire 70 are attached, via further pulleys 77, 78, 79, to an optical arrangement 20, eg a lens of a copying machine, so that movement of the second wire 70 causes translation of the lens 20 along non parallel guide edges 22a, 22b of support 21. This translation of the lens 20 allows for simple control of magnification.

Patent GB-2323982-A (GB)
Title: Mains flicker reduction
Inventor: HAMER RICHARD ASHLEY
IPC: G03G15/00
Filed: 1997-04-01
Abstract: Control of a mains powered high current element 130, such as a heater element in a washing machine or, particularly a fuser system for reprographic apparatus, is effected by use of a multi-tap transformer 110, whereby the element 130 can be switched between at least two non-zero power levels. An existing control system, which produces a duty cycle or phase angle control signal, may be modified by translating the existing control signal into a signal which controls a switch 140 to select the transformer tap giving the equivalent average power output from the fuser 130. Tap changing occurs at mains voltage zero crossings. The arrangement reduces the number of times the fuser is switched between off and on in a given time period, thereby reducing the amount of flicker in adjacent mains powered lighting.
Patent GB-2314737-A (GB)
Title: Rapid handoff in a TDMA wireless communication system
Inventor: KOTZIN MICHAEL D
IPC: H04B7/26
Filed: 1997-05-23
Abstract: In a wireless communication system transmitting in time frames such as a GSM system, a mobile unit monitors its current traffic channel signal quality (bit error rate or frame error rate). If the quality degrades to a predetermined threshold, control channels of adjacent base stations are immediately monitored by interrupting and ignoring the traffic channel information in a current receive slot. The time delay necessary for an idle frame to align with a base station control channel SCH frame is eliminated and potential handover candidates are thus rapidly found. The lost speech or data on the traffic channel can be recovered using speech extrapolation techniques. Traffic channel interruption can also occur when insufficient neighbour cell information is available at the beginning of a call or immediately after handover. The mobile requests a handover when a stronger base station is found. If cell sites are synchronised the mobile Unit can intelligently interrupt speech when it knows a SCH frame of the base station control channel can be monitored. The invention applies to any TDM or TDMA system for cellular radiotelephones, pagers, electronic organizers or computers.
