Title: Improvements in and relating to safety release mechanisms
Inventor: FLETCHER STEPHEN BALDWIN DUNWI
IPC: G21C9/027
Filed: 1958-09-08
Abstract: 872,092. Controlling reactors. NUCLEAR POWER PLANT CO. Ltd. Aug. 14, 1959 [Sept. 8, 1958], No. 28768/58. Class 39(4). A safety release mechanism for releasing a member from a parent member in response to changes in pressure in a fluid in which the releasable member is immersed comprises a push rod attached to the releasable member and operable to trip a latch mechanism joining the releasable member to the parent member and a pressure sensitive device located in the releasable member and forming an enclosed space therein; the pressure sensitive device being responsive to pressure changes between the enclosed space and fluid surrounding the releasable member and exerting a force on the push rod sufficient to trip the latch mechanism when a predetermined pressure change occurs. Fig. 1 shows an arrangement for releasing a control or safety rod in a gascooled nuclear reactor. The control rod comprises a tube 2 containing boron and arranged between inner and outer stainless steel tubes 1, 3. The outer tube 1 is welded to a tube 21 attached to a lifting head 13. A bellows 6 provided with an orifice 9 forms an enclosed chamber within the control rod so that if the gas pressure outside the rod falls, the bellows expand pushing up push rods 10 which act on a plate 15 and a further push rod 14 to actuate a latch mechanism and release the control rod. If the temperature of the gas around the control rod rises excessively tube 21 expands thus causing an end cap 11 to press down on the ends of levers 26 which push up the rods 10 and release the control rod. To retrieve the rod from the reactor the member 20 is lowered by a rope or chain until it contacts the top of the rod where, due to the geometry of the system, the pawls 24 under the weight of member 20 are rotated into the locking position by cam action of the pawls 24 on the inclined faces of lifting head 13.

In apparatus, for mounting tyres on wheel rims, wherein a lever 1 has journal means 6 co-operating with a pillar mounted coaxially with the wheel and carries an assembly comprising a flanged roller 11 and a guide roll 14 whereby when the lever is swung about the pillar the guide roll 14 guides the tyre bead over the wheel rim flange and under the flange 11b of the roller 11, said roller 11 bearing on the rim with its flange 11b overhanging the rim flange edge, the journal means 6 and the said assembly are relatively movable along the lever 1 during the swinging movement of the lever about the pillar so that the assembly is at all times located in the correct operative position by the wheel rim flange. As shown the lever 1 has a neck 16 at one end terminating in a ball 15, for use in removal of a tyre from a wheel rim, and at its other end has a depending lug 2 from the lower end of which a stub axle 10 extends parallel with the lever 1 to carry the flanged roller 11. Laterally spaced ribbed vertical plates 3, 4 extend from the side edges of the lug 2 to provide an extension of the lever 1 and define a vertical slot in which is slidably mounted the journal means 6. The journal means 6 comprises vertically spaced horizontal apertured plates 8, 9 interconnected by two vertical members 7 so that they overlie the edges of the plates 3, 4 with their apertures aligned to sleeve over the pillar (not shown). The members 7 are of greater height than the depth of the slot to provide for rocking movement of the lever 1 relative to the journal means 6. The guide roll 14 is carried on a vertically disposed stub axle 13 depending from a bracket 12 which extends laterally of the lever 1 from the underside of the plates 3, 4 adjacent the lug 2, the guide roll 14 being formed with a waist about mid-way between its ends and being dimensioned so that its lower end face lies above the level of the lowermost point of a hub 11a of the flanged roller 11. This hub 11a of the roller 11 is cylindrical, to run on the lateral surface of the wheel rim flange, and connects into the flange 11b which projects outwardly at an acute angle to the hub to hook over the rim flange edge, the flange having a frustoconical end face 11d to engage the tyre side wall and derive a thrust therefrom to maintain the flange 11b firmly against the rim flange edge. In an alternative arrangement the necked ball end 15 of the lever 1 may be replaced by a spade formation.
