Patent GB-2076195-A (GB)
Title: Non-home-run zoning system
IPC: G08B13/00
Filed: 1981-05-20
Abstract: Zone indication is provided for a monitoring and control system by providing the system's sensors 12 and control unit 10 with counters 30, 32 which are simultaneously incremented with clock pulses from control unit 10. In one embodiment, each sensor output is enabled only during the occurrence of a corresponding count (jumper) from its counter. When the sensors are used to sense alarm conditions, the sensor sending an alarm signal is identified when an alarm condition signal exists simultaneously with a particular count from the counter at the control unit 10, with the particular count indicating which sensor is sending the alarm signal. Remote data can be transmitted between counter clock pulses. Should transmission of complex data be required, the counter clock pulses are inhibited and complex data is then read out, from the sensor actuated when the counter clock pulses are inhibited, at a rate governed by a different type of pulsed signal transmitted to the sensor. Zone indication signals can be made compatible with sensor control signals so as to establish compatibility with previously installed in-place systems. <IMAGE>

Title: Fluid control valve
Inventor: EVANS GERALD JOHN
IPC: F16K43/00
Filed: 1983-02-10
Abstract: This invention relates to fluid control valves. It has particular application to such valves in which the internal parts of the valve may be removed for maintenance whilst the valve is "under pressure", that is to say fluid is being supplied to and from the valve whilst the maintenance of the valve is carried out. An improved valve of this type is disclosed in our co-pending U.K. application No. 8123569. One of the situations in which it is particularly valuable to be able to maintain a valve whilst under pressure is when the valve is being used as a stop-cock valve such as in the ordinary domestic water supply. As shown in Fig. 18 the valve 231 has a base plate 233 screwed on to its stem with a chamber 232, with a sealed lid 239, attached to the base plate. Threaded flange 236 is provided for attachment of a standpipe. The crutch handle 2 is removable with a dust cap 4 to expose the internal parts of the valve. Special tools are provided to enable the valve to be maintained whilst under pressure. <IMAGE>

Title: Sustained release lithium-containing tablets and method for their manufacture
Inventor: TRIGGER DAVID JOHN
IPC: A61K9/20
Filed: 1983-04-19
Abstract: The release pattern of sustained release lithium carbonate tablets is improved by using a particular form of lithium carbonate material. This should have acicular crystals with a substantially monomodal particle size distribution in which the curve showing volume percentages of particles of different sizes shows a peak at a particle diameter of between 10 and 25  mu m. Moreover not more than 20% by volume of the material should have a particular diameter above 30  mu m. A preferred sustained release agent is a mixture of glyceryl mono-di- and tri-esters of straight chain saturated fatty acids. The tablets may be made by a moist granulation technique, followed by screening to ensure a granulate of appropriate grain sizes, after which the granulate is compacted into tablets.

Title: Fusible element
Inventor: GRATTON ARTHUR DAVID
IPC: H01H85/055
Filed: 1983-05-05
Abstract: A fusible element comprises a continuous strip 1 of copper, or a composite strip comprising end sections of copper and a bridging section of silver; at least a portion of the copper strip or at least one copper end section being adapted for fusion upon passage of a short circuit current. A coating or body 3 of solder overlies an intermediate portion 2 of the copper strip or the silver bridging section and will alloy eutectically with copper or silver upon fusion arising from passage of a sustained overload. At least portions of the copper strip 1 or copper end sections immediately adjacent the intermediate portion 2 or bridging section have an overlying layer of e.g. nickel which, on occurrence of a sustained overload, will prohibit or resist dispersion of the solder 3 from the intermediate portion 2 or bridging section and over the copper strip 1 or end sections. The fusible element is reliable and the nickel layer prevents oxidation and thus deterioration of the fusible element. <IMAGE>

Title: A data processing system including an infra-red coupled remote data entry device
Inventor: BEAVERS JOHN ANDREW
IPC: H04L25/493
Filed: 1984-07-03
Abstract: A battery powered keyboard entry device (1) includes an infra- red generator for coupling the device to a processor (2) which includes an infrared receiver. Each input binary signal (A) is transmitted as a few (e.g. two or three) short infra-red pulses (D) indicating the leading edge of the binary signal. In the receiver, the receiving groups of pulses, after detection and amplification, are stretched by a single-shot circuit (22) to produce binary signals of substantially the same length as the original binary signals. As each transmission is substantially shorter than each binary signal, power consumption in the keyboard entry device is substantially reduced as compared with a system in which the infra-red pulses for each input signal extend over the input signal length. <IMAGE>

Title: Self-circulating solar water heater
Inventor: ROBERTSON THOMAS JOHN MCNEEL
IPC: F24S10/60
Filed: 1985-01-12
Abstract: In a water heating system using solar energy heat collecting surfaces the water pump is powered by solar energy which heats and thereby raises the pressure of a gas in a chamber 3. This pumps water through T-pieces 5 and non-return valve 8 into reservoir 7. The temperature of this gas is lowered by intermittent discharge of water over the surface of the chamber (e.g. via syphing). This alternating heating and cooling is used to give a water flow over surfaces exposed to solar radiation. <IMAGE>
