Patent GB-2313721-A (GB)
Title: Battery charging; backup power supply
Inventor: KITAGAWA SEIYA
IPC: H02J9/06
Filed: 1996-12-02
Abstract: In a first arrangement, a charging switch 35 is ON/OFF controlled by a charge control 36 during charging of a battery 33 from an external supply 31 which also supplies a load 43, and the battery 33 discharges through the same switch 35 to supply the load 43 when the external supply is not available, switch 35 being maintained ON by a power status detector 34 during battery discharging. This reduces the number of back current preventing diodes that are required compared to the prior art (Fig. 1). In a second arrangement, charge current and discharge current flow through the same current sense resistor R connected to a current sensor 37, which is used not only for ON/OFF PWM control of switch 35 during charging but also for turning off switch 35 in response to overcharge and for turning off a discharge switch 40 in response to overdischarge. This reduces the number of current sense resistors compared to the prior art (Figs. 1,2). The first and second arrangements may be combined, Fig. 8, or discharge current may flow through another switch (51, Fig.9) in the second arrangement rather than through the charging switch. Charge control 36 may give a constant current/constant voltage characteristic for Li-ion batteries, or constant current for Ni-Cd or Ni-MH. Power status detector 34 may operate by sensing the voltage from external supply 31 (Figs. 10A, 10B), or by sensing the direction of current flow in current sense resistor R (Fig.11).

Title: Water saving insert for W.C. cistern
Inventor: KERWIN COLIN JOHN
IPC: E03D1/14
Filed: 1997-10-16
Abstract: A water saving device for water storage vessels such as flush cisterns, the device comprising a perforated plastics bag (11) containing, in granular form, a super-absorbent polymer which, when wetted, expands to two hundred times its pre-absorption volume.

Patent GB-2317072-A (GB)
Title: Apparatus and method for increasing the intelligibility of a loudspeaker output and for echo cancellation in telephones
Inventor: RASMUSSON JIM A J
IPC: H04M9/08
Filed: 1996-05-30
Abstract: A telephone having a method and apparatus for increasing the intelligibility of the loudspeaker output and for echo cancellation. The telephone includes an intelligibility booster for processing a speech input signal to generate an intelligibility-enhanced signal. The intelligibility booster includes a revereration signal path for generating a reverberation signal, a direct signal path for generating an anenuated direct signal corresponding to the input signal, and an adder for combining the reverberation signal and direct signal to generate the intelligibility-enhanced signal. The reverberation signal path includes an intelligibility-information emphasizer followed by a reverberation unit. In the preferred embodiment, the intelligibility information emphasizer is a high pass filter and/or compressor that generates an intelligibility-dense signal to generate the reverberation signal. The reverberation unit processes the intelligibility-dense signal which includes a stream of reverberation sequences of weighted delay signals. The weighted delay signals of each reverberation sequence are weighted according to an exponential decay pattern and so that the time delays between weighted delay signals tend to increase over the reverberation period. In response to the intelligibility-enhanced signal, a loudspeaker outputs a speech sound wave having an artificial reverberation component corresponding to the reverberation signal. An echo canceller uses the intelligibility-enhanced signal in cancelling an echo component in a microphone signal generated by the microphone of the telephone.

Title: Sealing member and valve closure member
Inventor: DOUST PHILIP GEORGE
IPC: F16K1/36
Filed: 1998-02-04
Abstract: A sealing member 10 for a valve 12 includes a body 14 defining a cavity 16 and, a resiliently deformable membrane 18 extending across a lower end 20 of the body 14. The membrane 18 is provided with an aperture 22 through which fluid can flow to enter the cavity 16. The valve 12 typically has an inlet 24, an outlet 26, and a seat 28 through which fluid must flow in order to pass from the inlet 24 to the outlet 26. The sealing member 10 is configured to seal against the seat 28. When the sealing member 10 is seated on seat 28 to at least partially seal the valve 12, fluid enters the cavity 16 through aperture 22 and, by action of fluid pressure in the fluid, forces the resiliently deformable membrane 18 against the valve seat 28 to further seal the valve 12.

Title: Frozen food defrost indicator
Inventor: WILLIS STUART CHARLES
IPC: G01K11/06
Filed: 1998-11-12
Abstract: A defrost indicator for providing a non-reversible visible indication of whether frozen food has been exposed to unacceptable high temperatures. The indicator comprises a liquid 13 and a coloured weight 12 housed within a container having a transparent part 11 and a non-transparent part 10. To prime the indicator the container is oriented with the non-transparent part 10 lowermost and then frozen to entrap the weight 12 within the frozen liquid 13. In use the indicator is inverted to the position shown in figure 3 and placed within a frozen food store. If partial defrosting of the food store occurs the frozen liquid 13 melts sufficiently to drop into the transparent part 11 as in figure 4. If complete defrosting of the frozen food store occurs the weight 12 will sink through the defrosted liquid 13 to rest on the bottom of the container as shown in figure 5.

Title: Routing signals through a wireless communication system comprising a network of linked nodes
Inventor: HUGHES PHILIP THOMAS
IPC: H04L45/42
Filed: 1997-12-18
Abstract: A wireless communication system comprises a network of nodes 2 connected by point-to-point links 3 using highly directional antennae. Each node determines if a received signal includes information for another node and if so, a signal including the information is transmitted to another node. Information is routed or hopped from node to node until it reaches its destination node. The nodes may be subscriber stations or repeaters. Various network topologies are described including fully interconnected, linear chain, tree, lattice, hypercube and combinations. Each link is associated with a distinct time slot and links may form loops to provide plural path choices each consisting of an even number of links to maintain synchronisation of transmission and reception between nodes. A copy of the information may be sent on a different path or the information may be split between two paths. Traffic is routed by addresses added at each node or by a central system controller, and may be determined by congestion or node . At least one link of a node may use a different frequency to prevent interference.

Title: Gambling machines connected to a further game of chance
Inventor: WATTS RONALD ARTHUR
IPC: G07F17/32
Filed: 1999-01-26
Abstract: A gambling machine system comprises a plurality of first games 1, each separately operable by a player using a coin or token, connected to a further game 2, which is operable when any one of a first set of results is obtained on one of the first games, to produce a second set of results where at least one of the second set of results generates a major prize. Preferably all the first games are of a standard type, e.g. reel 4 fruit machines, and are mounted in a row in a common housing with the further game adjacent the row. The further game may be the same as the first games, e.g. a reel 3 fruit machine, but may have a different number of reels, symbol positions on the reels, or number or type of symbols. The further game may be triggered automatically and have no player operated controls or the player may be offered a choice of actuating the further game. The further game may also be operable multiple times upon a single first result set outcome. The winning conditions of the first games may be identical or may be different and the further game of chance may compensate for any difference. Preferably prizes may be won from the individual machines or from the further game of chance, and a prize won from a first game may be gambled on the further game for a greater prize.
