Title: Improvements in and relating to devices for sensing the relative location of two nuclear fuel elements
Inventor: COOKE BRIAN FREDERICK
IPC: G21C17/10
Filed: 1969-12-09
Abstract: 1279875 Fuelling reactors NUCLEAR POWER GROUP 27 Aug 1970 [9 Dec 1969] 59945/69 Headings G4F and G6C An arrangement for indicating the correct seating of an upper nuclear fuel element 4 upon a lower fuel element 9 during a fuelling operation employing a grab 1 having jaws 5, comprises providing a gas supply in the hoist cable 2 and providing each fuel element with a gas passage 7 terminating in a perpendicular passage 8a in a projection 8. A spring-loaded dowel 3 in the grab makes a gas-tight connection with the element 4 so that during a lower operation the gas flows freely through that element until the projection 8 enters the passage 7 of the element 9 whereupon the passage 8a in element 4 is obstructed. This obstruction causes a change in pressure in the cable 2 which is detected by a pressure gauge.

Filed: 1968-12-30
Abstract: 1,273,567. Injection moulds. IMPERIAL CHEMICAL INDUSTRIES Ltd. 15 Dec., 1969 [30 Dec., 1968], No. 61659/68. Heading B5A. [Also in Division B3] An injection mould comprises male and female mould halves wherein metal shells are provided with cooling pipes 6, 16 and thermocouples 7, 15, and are set in aluminous cement in bolster frames.

Patent GB-665245-A (GB)
Abstract: 665,245. Thermal switches. PHILIPS ELECTRICAL, Ltd. Aug. 4, 1949. [Aug. 7 1948 Dec. 2, 1948] Nos. 20322/49, 20323/49. Drawings to Specification. Class 38 (v). [Also in Group XXXV] A thermal lock-out switch for preventing continued operation of the starter switch of a discharge tube, after a number of unsuccessful attempts to start, is opened by heat developed in the starter switch itself and is then maintained open by a heater resistance previously short-circuited by the lock-out switch. If the starter switch is of the electro-magnetically operated type, the bimetal element of the lockout switch may be carried by a metal member which also carries the fixed contact of the starter switch and through which the heat due to arcing at the starter contacts is transmitted to the bimetal element. In the case of a starting switch of the glow discharge type, the lock-out switch may be located in the same envelope as the starter, the thermally responsive element of the lock-out being in direct contact with one electrode of the starter. Alternatively, the lock-out switch may be strapped to the outside of the envelope of the starter switch, one electrode of which may extend to the inner wall of the envelope adjacent the lock-out and which may be bimetallic so as to press outwardly into close contact with the wall under the heat from the discharge.

Title: Automatic exhaust stack damper control
IPC: F27D21/00
Filed: 1978-07-24
Abstract: In a fuel-burning device having a combustion chamber, (12) a burner (19) with a control, an exhaust stack (15) connected to said chamber, an air diverter (17) in said stack and a thermostat connected to said burner control; the improvement which comprises a damper section (21) in the stack downstream of the diverter. The damper (31) is disposed within and journalled upon bearings (33) attached to the damper section. A motor (51) on the damper section has an output shaft (49) connected to the damper and includes a rotary switch (67) on said shaft. An electrical circuit includes a relay switch interconnecting the thermostat, burner control, motor and rotary switch. The motor output shaft is intermittently rotatable through successive arcs of 90 degrees, through 360 degrees, whereby the damper normally closes the stack preventing escape of room air therethrough when the burner is not operating. The thermostat, when calling for heat, closes the circuit to the motor rotating the damper 90 degrees to open position and successively energizing the burner. The thermostat, when no longer calling for heat, closes a portion of the circuit activating the motor causing rotation of the damper an additional 90 degrees in the same direction to stack closing position and to successively deenergize said burner after the damper and rotary switch have rotated several degrees. The damper has a weight (55) biasing it to open position. A fusible link (43) interconnects the motor output shaft (49) and damper whereby, if the burner fails to shut off with the damper closed, hot exhaust gases fuse the link and the damper rotates automatically to open position. <IMAGE>

Title: A method of, and apparatus for, detecting or monitoring the movement of a chain
IPC: G01B7/04
Filed: 1979-10-04
Abstract: Apparatus used to detect the movement of a chain, such as a plough drive-chain of a mineral mining installation, employs one or more ring-like inductive sensing devices 10 surrounding the chain.
