Title: Temperature control means
IPC: A47J27/62
Filed: 1971-12-21
Abstract: 1372698 Automatic control of temperature HEATING EQUIPMENT Ltd 21 Dec 1971 [22 Dec 1970] 60893/70 Heading G3R  [Also in Division F4 and H2] In a water boiler, when water in a vessel 1 Fig.1, reaches boiling point steam will be generated at such a rate that it passes through apertures 8, 9 with such velocity that it impinges on a thermostat 10 in a compartment 7 which thermostat accordingly operates a switch 11 of an electric immersion heater 2 cutting the heater off. Steam produced prior to boiling point will not operate the thermostat but will pass mostly via passage 8, to a compartment 6 and is vented to atmosphere through a perforated cover at the upper end thereof. The frequency at which the thermostat cuts-on and cuts off the heater depends upon the differential temperature at which it is set, the water being maintained at or about its boiling point. Alternatively the thermostat may control the supply of gas in the case of a gas-fired boiler.

Abstract: 1,221,376. Mercury cells activated with ammonia. HONEYWELL Inc. 23 Dec., 1968 [29 Dec., 1967], No. 61204/68. Heading HlB. An electric cell activateable by addition of ammonia comprises a cathode current collector 3 in contact with active material 4 consisting of a finely divided mixture of an ammoniated mercuric salt and mercury or a finely divided mercurous salt capable of disproportionating into such a mixture when contacted with ammonia.

The mixture may be deposited from a slurry in water, toluene or acetone. The mercurous salt may be treated with ammonia outside the cell, inside the cell before activation or inside the cell at the same time as activation. The ammonia may be liquid or gaseous and may contain 1 mole per cent or more of an ionizing solute, e.g. KSCN, NH 4 SCN, LiBF4 or CH 3 COOK. Alternatively, the ionizing solute may be present in the cell. In a particular embodiment, cathode current collector 3, cathode active material 4, separator 5, anode 6 and plastics cover 8 are stacked in cylindrical plastics container 1.

Title: A device for use in driving instruction or physiotherapy
Inventor: RATCLIFFE GEORGE DENNIS
IPC: G09B19/16
Filed: 1968-12-24
Abstract: 1,260,849. Simulated steering wheel arrangement for driving instruction. G. D. RATCLIFFE. 22 Dec., 1969 [24 Dec., 1968], No. 61467/68. Heading B7H.  A portable simulated steering wheel arrangement for driving instruction comprises a steering wheel 1 secured to a shaft 2 mounted in brackets 3, 4 attached to a base 5 provided with suckers 6 enabling the unit to be placed on a table and retained in position. A pair of band brakes 21 surround a drum 28 on the shaft 2 and are manually adjustable to vary the resistance to rotation of the wheel 1. In addition a bush 17 surrounding the shaft 2 has a section radially movable under the influence of a spring strip 18 to provide a permanent damping effect on the movement of the wheel 1 by pressing on the shaft 2. The drum 28 is freely mounted on the shaft 2 and has a pin 29 which projects into a recess of a disc 30. A coil spring 31 surrounds the shaft and has its end projecting on either side of a dowel 32 in the disc 30 and also of the pin 29. Consequently rotation of the wheel 1 and shaft 2 causes disc 30 and its dowel 32 to tighten the spring 31 until the effort is sufficient to move the pin 29 and drum 28 against the frictional grip imposed by the brakes 27. Should the latter be such that the spring fails to move the drum ultimately one or other edge of the recess of the disc 30 engages the pin 29 and the drum is then positively rotated by the shaft 2. To enable the effect of the hand brakes to be increased or decreased brackets 20, 26 support a handle 7 coupled to a disc 8 having arcuate slots which engage projections 11 extending from the bands 27 such that rotation of the disc 8 by handle 7 causes the projections to move towards or away from each other to tighten or loosen the bands. The opposite ends of the bands have projections 22 adjustably secured to brackets 23, 24.

Title: Helically corrugated tubing
IPC: F16L9/06
Filed: 1978-08-22
Abstract: The invention relates to improved helically corrugated tubing with corrugations of variable depth which may be manufactured in a twisting machine by rotating one end of a deformable tube T relative to the opposite end and simultaneously applying axially directed forces to the tube to progressively develop the helical corrugations in the tube wall. The depth of the corrugations is varied by means of a tapered mandrel 50 which is located within the tube while the corrugations are being formed. Tubing sections with variable depth corrugations define flow paths in which the effective cross- sectional area varies correspondingly, and such sections are useful in various heat exchangers. <IMAGE>

Patent GB-2049976-A (GB)
Title: Improvements in or relating to clamps
IPC: G02B6/38
Filed: 1979-05-23
Abstract: A clamp for an optical fibre (1) has a sleeve (14) into which the optical fibre is inserted in a bore (17) and which has slots at each end (15; 16). The sleeve (14) is housed within a connector (4) which has two parts (5, 6) which are screwed together. The screwing together of these parts (5, 6) causes internal surfaces (24a, 24b) of the connector to abut the ends (15, 16) of the sleeve (14). This reduces the width of the slots and hence the circumference of the bore (17) which then grips the optical fibre (1). The optical fibre (1) is thus gripped securely within the connector (4). Hence one end (2) of the optical fibre (1) can be accurately located in a suitable position, relative to the end face (8) of the connector (4). The connector (4) can then be located in a socket (not shown) by means of a plug (26) which screws into the socket. <IMAGE>
