Patent GB-2178759-A (GB)
Title: Electrochemical ion exchange
Inventor: BRIDGER NEVILL JOHN
IPC: B01J49/00
Filed: 1986-06-13
Abstract: Ion exchange material having ions absorbed thereon is regenerated by incorporating it into a compartment of an electrochemical cell defined by a cell separator permeable to said ions and including a working electrode. The ion exchange material and the working electrode are not bonded to one another but are in sufficiently close proximity for the pH of the electrolyte adjacent the material to be controlled by the polarity of the working electrode and the current passing. Thus, at an appropriate pH during operation of the cell, the ions are eluted into the electrolyte. Ion exchange material thereby regenerated may be removed from the cell, used to extract ions from an aqueous solution and subsequently returned to the electrochemical cell for regeneration.

Title: Water supply apparatus
Inventor: BRIGGS PETER
IPC: F04D15/00
Filed: 1987-11-19
Abstract: Apparatus for supplying water under pressure to two outlets comprises two pumps 1, 2, a shuttle valve 6 connected between the outlet ducts 5 of the pumps, a pressure operated switch 15, and a diaphragm tank 18. The shuttle valve is responsive to fluid pressures in the outlet ducts to isolate the pressure operated switch and the diaphragm tank from the outlet duct of one of the pumps when the fluid pressure in that outlet duct is greater than the fluid pressure in the other outlet duct. Thus when one or both of the outlet ducts is supplying water the pressure operated switch will maintain the motor in operation. Two motors may be provided to drive the pumps, both motors being connected to a single pressure switch. <IMAGE>

Abstract: A resistive-divider current sensor employs a first resistor R1, e.g. a disk 22, and a second resistor R2, e.g. a wire 32, of substantially larger resistance connected in parallel. The current I entering and leaving at terminals 30 divides between the resistors according to the ratio of the resistances, and an output signal, reduced at least in accordance with a ratio of resistances is obtained from the second resistor. A current transformer 15/40 may employ the second resistor as a primary to step down further the current in the output signal. Resistive heating is reduced by using resistors of low temperature coefficient material. …<IMAGE>…

Title: Portable water-purifying devices
Inventor: MEAD ROBERT JAMES
IPC: C02F9/00
Filed: 1988-02-29
Abstract: A portable water-purifying device comprises a primary disinfecting chamber (50) and a combined secondary disinfecting chamber and post-filter (30). Water to be purified can be scooped by means of a cover (12) into a receptacle (90) containing a pre-filter media (39) of preferably silvered activated carbon beneath a coarse entry filter pad (102). From that receptacle (90) the water enters the primary disinfecting chamber (50), flowing downwards through nine or so passage-forming segments (22) filled with a microbiocide (56), to effect primary disinfection, that is, to kill a substantial number of pathogenic organisms, but probably not all. Each passage (22) is at least three times longer than it is wide, to prevent channelling of the water through the microbiocide. Disinfectant from the microbiocide (56) enters the water as it passes through. The disinfectant-containing water from the primary disinfecting chamber (50) enters the combined secondary disinfecting chamber and post-filter (30) - ''second chamber (30)'' - down a centre tube (44) to be stored for, say, two minutes or so for any remaining viruses, as well as any other remaining pathogenic organisms, to be killed. The second chamber (30) is then inverted, whereupon the water flows through a charge media (48) of preferably silvered granular activated carbon which effects post-filtration, substantially removing the disinfectant from the water, which flows thence into a drinking cup (10).

Title: Coding/decoding analogue signals using master and two slave codebooks
Inventor: MOULSLEY TIMOTHY JAMES
IPC: G10L25/27
Filed: 1990-09-28
Abstract: In a CELP analogue signal coding system, sequences from master codebook 40, which is one dimensional, are filtered in unit 42 and orthogonalised in unit 68 to give codebooks (70, 72) containing even and odd frequency sequences. input analogue signals 20 are filtered in units 34, 36 and orthogonalised in unit 66 to give odd and even frequency sequences. One odd (c<i)<n)) and one even (c<i)<n)) frequency codebook sequence are amplified and compared in units 78, 80 with the filtered and orthogonalised input signals and an optimum pair of sequences and gains are selected. Since odd and even frequency components are orthogonal, sequences are selected from codebooks 70, 72 and compared in units 78, 80 with the filtered incoming analogue signals entirely independently. This effects a reduction in codebook search complexity over a one codebook system. Other means of orthogonalising the codebook, and the incoming sequences, include frequency or time domain divisions. This can be used for speech or video input. <IMAGE>

Title: Radio receiver interference cancelling system with noise reduction features
Inventor: TALWAR ASHOK KUMAR
IPC: H04B1/12
Filed: 1991-02-19
Abstract: An auxiliary antenna 66, directional couplers 68, 78, a synchronous detector 72 and a signal controller 76 provide an interference cancellation signal, controlled in amplitude and phase, for subtraction 82 from the signal output of a receiver antenna 60, and in order to prevent the cancellation system injecting noise into the receiver when no interfering signals are present, the latter condition is sensed to open a switch 98 between controller 76 and subtractor 82. The switch 98 may be controlled by a comparator 96 which compares the signal from auxiliary antenna 66, or from receiver antenna 60, (Fig. 6), with a reference. Alternatively, the comparator 96 may compare the reference with the ratio of the signal powers at the antennae 60 and 66, (Figs 4, 5). Switches (100), (102), (Figs 3, 5) providing a path from antenna 60 to receiver 62 bypassing subtractor 82 may be used instead of the switch 98. <IMAGE>
