IPC: G21C3/33
Filed: 1966-02-11
Abstract: 1,113,465. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 3 Feb., 1967 [11 Feb., 1966], No. 6259/66. Heading G6C. A fuel element in which a cluster of parallel fuel rods is supported and which is intended to be positioned in a fuel element channel in endto-end association with one or more similar fuel elements to form a unitary assembly which is manipulatable into and out of the channel, is characterized by deformable latch means for engagement with non-deformable latch means of an endwise adjacent fuel element, and by releasable locking means for holding the latch means in the engaged position. In the embodiment. shown in Fig. 3, a guide tube 1 (1<SP>1</SP>) extends axially along each fuel element through intermediate fuel rod locating grids (not shown) and a top support grid 6. At its lower end, the guide tube 1 (1<SP>1</SP>) is disposed within a sleeve 2 welded to radial supports 3 which form part of a fuel rod support grid 4. The guide tube 1(1<SP>1</SP>) is disposed within a sleeve 7 welded to the support grid 6. Members 91 formed at the upper, end portion of sleeve 7 have part-annular projections 10<SP>1</SP> with inclined surfaces 12<SP>1</SP>, 20. An inwardly extending annular projection 13<SP>1</SP> formed at the lower end of sleeve 2 has inclined surfaces 15<SP>1</SP>, 21. Relative axial movement of the adjacent fuel elements towards one another causes the members 9<SP>1</SP> to be moved inwardly until the projections 101 have passed the projection 131. A lifting member 18<SP>1</SP>, or its enlarged portion 191 as shown, as the case may be, serves to prevent unwanted unlatching. After removal of the lifting member 18<SP>1</SP>, the fuel elements may be separated by relative axial withdrawal only, the inclined surface 21 engaging the inclined surfaces 20 and serving to move the members 91 inwardly until the projections 10<SP>1</SP> can pass the projection 13<SP>1</SP> and pass out of the sleeve 2. In two alternative embodiments, a latch release member associated with the latch means but movable relative thereto serves to effect positive release of the latch means following release of the looking means, and the locking means comprises a member associated with the latch means and movable relative thereto, respectively.

Abstract: 677,176. Hydraulic shock - absorbers. McINTYRE, B. D., McINTYRE W. D., and McINTYRE, C. S., (trading as PATENT DEVELOPMENT CO.). March 13, 1950 [Dec. 17, 1949], No. 6268/50. Class 108(iii) The piston rod of an hydraulic shock-absorber has a fluid flow orifice 37, the effectiveness of which is controlled by an associated movable valve member 39, operable by the fluid pressure fluid thus being able to flow from one side of the piston to the opposite side via a piston rod passageway 49, the piston also having fluid flow passage means 55 and associated valve means 67, the arrangement being such that at low fluid pressures the valve 67 is closed, and flow takes place through the orifice 37, while at increased pressure the valve member 39 closes the orifice 37, and the valve means 67 opens. The valve 39 comprises a plunger slidable in an axial bore 33 in the piston rod. A spring 51 normally retains the plunger 39 in the position shown, in which a tranverse passageway 43 and circumferential groove 42 in the plunger wall, are in alignment with the orifice 37. The valve means 67 comprises laminated discs which rest on spaced lands 69 and are loaded by a spring 73. The spring abutment 75 comprises a clamping nut for securing the piston rod on the piston body 19. Flow in the opposite direction through the piston occurs through outer ports 53 controlled by a starspring loaded disc-valve 57. A base valve assembly 29 comprises a valve body 76 having inner and outer circumferential series 79, 77 of ports. flow through which is controlled respectively by a stack of discs 109 and a star-spring-loaded disc-valve 103. The valve 109 rests on a single land 111 and is secured by spinning over the edge 113 of a valve cage member 83. A hollow enlarged head-portion of the member 83 has an annular shoulder 95 formed by a washer which forms a stop for a hexagonal shaped valve member 91, (Fig. 2.). The valve member 91 can be driven by fluid pressure against the action of a spring 99 to seat on a shoulder 89 of the member 83 and cut off liquid flow therethrough. In the position shown, flow can take place between the inner periphery of the shoulder 95 and the flat sides of the valve member 91. Operation. On normal compression movement, liquid passes round the valve member 91 to the reserve chamber. On faster compression movement, the valve 91 is seated and prevents flow through the valve cage member 83, but the disc valve 109 lifts. On normal rebound, the valve 67 remains closed and flow takes place through the orifice 37 and passageway 49. On faster rebound, the plunger 39 is displaced and cuts off flow therethrough, but the disc valves 67 are opened. The disc valves 67 may open in advance of the closing of the plunger flow-passage, also the valve 109 may open in advance of the closing of the valve 91.
