Abstract: "CHIMNEY CLOSURE APPARATUS"        ABSTRACT OF THE DISCLOSURE               A supporting frame is engaged within the upper end of is the chimney and/sealed around the base thereof adjacent the flue liner and supported by overlapping pegs extending from the frame and engaging the upper edges of the flue liner or chimney.  In one embodiment a damper plate is hinged to one side of the lower end of the frame and hangs vertically against the side of the flue liner when open but is pulled upwardly into engagement with the under side of the frame when closed.  In another embodiment, the damper plate is hinged centrally of the frame base and hangs vertically, when open, with the upper half extending above the frame base and the other, weighted half, extending below the frame base.  Vertically staggered halves of damper plate engag-ing strips are provided one on each half of the frame with the upper half of the damper plate, when closed, engaging the upper surface of one of the strips and the lower half of the damper plate engaging the under side of the other of the strips.  In both embodiments, the damper plate is actuated by cable but will move to the open position if the cable breaks or becomes dis-connected from the damper plate.

Abstract: ABSTRACT           The invention provides a method of operating a cascade gas separation process and a gas separation cascade (10) useful for uranium refining and employing a carrier gas. The method and cascade of the invention involve arranging relative  gas flow rates between at least some modules (12) in the cascade so that the relative proportions of process gas leaving and entering each of said modules are such that there is a  substantially constant molar flow rate of gas in each direction along the cascade through said modules. The proportion of carrier gas relative to process gass increased in opposite directions from the feed (14) to the opposite ends (20, 22) of the cascade and the modules through which the constant molar flow rate takes place have substantially the same size, capacity and construction.

Abstract: ABSTRACT   A safety belt buckle comprises a tongue part and a latch part adapted to releasably engage the tongue part in locking relationship, said latch part having a locking member pivotally mounted therein and arranged to be set between a position releasing said tongue part and a position locking said tongue part.  A spring urges the locking member to pivot to its releasing position and the latch part further includes a detent member resettable between a detent position in which said locking member is prevented from being reset from its locking position and a releasing position in which the locking member is permitted to pivot to its releasing position.  An ejector part is arranged to eject the tongue part by the action of the spring then the locking member is reset to the locking position.   A link mechanism connects the detent member to the ejector part, such link being loaded by the spring attempting to move said ejector part to an outer position.  The link is further arranged so as to bring with it the detent member away from its releasing position when the ejector part is pushed in by means of said tongue and so as to move the detent member to the locking position by the action of said spring and, when the detent member is moved from its locking position, so as to move the detent member to the releasing position as well as to move said ejector part to its outer position by the action of the spring.  The invention overcomes the problem of partial locking, whilst providing a buckle which is simple to manufacture but meets stringent standards of operational reliability and durability.

Abstract: POWER STEERING PUMP                         Abstract A pump has an inlet, an outlet, and a fluid displace-ment mechanism operable to pump fluid from the inlet to the outlet.  A cheek plate in the pump is movable to control a flow of fluid from the outlet back to the inlet and thereby to vary the fluid flow to a hydraulic system supplied by the pump.  Acting on different and unequal surface areas of the cheek plate are two fluid pressure forces.  The fluid pres-sure force is provided by fluid pressure in a cheek plate control chamber.  The force acts with a spring biasing force to bias the cheek plate into a position blocking the flow of fluid from the outlet back to the inlet.  The second fluid pressure force acts on the cheek plate against the spring force and the first fluid pressure force.  A first orifice communicates the pump outlet with the hydraulic system, a second orifice communicates the system with the control chamber, and a third orifice communicates the control chamber with the pump inlet.  The second and third orifices are sized relative to each other to provide, at a predetermined rate of flow to the system, a fluid pressure in the control chamber which has a ratio to system pressure generally equal to the ratio of (a) the area of the cheek plate surface on which the second fluid pressure force acts to (b) the area of the cheek plate surface on which the first fluid pressure force acts.

The device (20) has a polymeric liner (22) that is bonded to the inside of the pipe, the liner being driven outwards into contact with the pipe on activation of a delivery arrangement (26) by heating the pipe from outside.   The delivery arrangement (26) may be of a shape memory metal or of a high modulus engineering plastics material.   The bonding material (24) is applied progressively to the inside of the pipe, thereby to preclude entrapment of air between the liner (22) and the inside of the pipe.
