Title: Improvements relating to water heaters
Inventor: GARDOM GEORGE WILLIAM
IPC: F24H9/20
Filed: 1967-08-04
Abstract: 1,236,934. Liquid flow heater. GARDOM & LOCK Ltd. 23 July, 1968 [4 Aug., 1967], No. 61009/70. Divided out of 1,236,933. Heading H5H. In an electric water flow heater comprising a block of insulation 10 with a passageway 13, 14 ... 28 containing one or more resistive heating elements 33, 34 controlled by a switch (not shown) actuated by pressure-responsive means connected to different parts of the flow passage so that, in use, the pressures in said parts act in opposition on the actuating means so that it will not respond to static pressure variations but will respond to a pressure differential between said parts, an automatic non-return valve 46 is provided in series with said passage to prevent reverse flow through the heater. The valve 46 comprises a cylindrical chamber 47 formed in body 10 into which extends a flanged plastics case 48. A rubber or plastics plunger 50 having an enlarged raised annular rim 51 slides in the case 48. An "O" ring 49a between the flange of case 48 and a shoulder of block 10 seals the chamber. Under static conditions, the plunger 50 overlies outlet port 14 in the side of chamber 47. Under forward flow the plunger 50 is urged into case 48 to expose the outlet port 14, and under reverse pressure the plunger 50 is forced downwards to close inlet bore 13. The flow heater is identical with that described in the Parent Specification.

Patent GB-2049998-A (GB)
Title: Improvements relating to pressure relief systems
IPC: F16K17/10
Filed: 1979-05-25
Abstract: A pressure relief system is provided for attachment to a pressure relief vessel and is required to provide rapid venting when an allowable maximum pressure is exceeded. The system incorporates a pressure inlet (5) which is normally in communication with a minor venting outlet (16) leading to a pressure relief device (17). A major venting outlet (13) is normally closed by a piston (10) which is held normally in an outer position within a cylinder (7) whose cylinder chamber (9) is in communication with the pressure inlet (5) via a narrow passageway (11). When pressure in the pressure vessel (3) exceeds the maximum this will cause operation of the device (17) resulting in the rapid drop in pressure in the chamber (9) so that a pressure difference applied to the two sides of the piston (10) will cause the piston to move to an inner position allowing the pressure inlet (5) to communicate directly with the major venting outlet (13) thus ensuring rapid venting. The pressure relief device (17) ideally comprises a rupture disc. Spring biasing means may be provided to hold the piston (10) lightly in its outer position. <IMAGE>

Patent GB-2030288-A (GB)
Title: Photo-electric fire detectors
IPC: G08B17/12
Filed: 1979-08-10
Abstract: A fire-radiation detector (Figure 3) comprises sensitive elements (R, B) having different spectral response ranges. The a.c. output of each element is amplified by a respective multistage amplifier (17, 20; 57, 60). The outputs of each pair of corresponding stages are applied to respective comparators (34, 44) each yielding an alarm output when the output of the element (R) sensitive to longer wavelengths exceeds that of the other element. To avoid malfunctions due to the circuitry saturating in the presence of strong radiation, a further comparator 23 produces an alarm signal if the d.c. level of such radiation received by element R exceeds a pre-set level. The detector can thus signal fires at a large distance without the danger of failure to signal a nearby fire due to saturation. <IMAGE>
