Title: Improvements relating to fluid shut-off valves
IPC: F16K31/42
Filed: 1959-10-16
Abstract: 897,225. Valves. FRAZER-NASH, A.G. Oct. 14, 1960 [Oct. 16, 1959], No. 35126/59. Class 135. Upon energizing a pair of solenoids 12 over a switch, not shown, a spring-loaded ball 3 is lifted a small distance off its seat by a rod 10 and allows compressed-air from an inlet 6 to flow via a filter 7 and through a duct 19 to move a piston 21 against spring-loading so connecting the duct 19 to the outlet 26 and translating a shaft 22 thereby opening contacts 27 and de-energizing the solenoids 12; a cam surface 23 on the shaft 22 also lifts the rod 10 to fully unseat the ball 3. When a release mechanism connected to the outlet 26 has been operated the pressure in the outlet 26 builds up and enters a reservoir 33 via an opening 32, the size of which is adjustable by a needle valve, not shown; when the reservoir pressure is high enough it moves a piston 30 to the left, and, through an extension 28, a piston 21 returns the parts to the positions shown so that the contacts 27 close and the ball 3 seats. Accidental operation of the release mechanism due to air leaking past the ball 3 is prevented by providing a vent hole in the duct 19 which is closed by the shaft 22 when it moves rightwardly. The armature extensions 13 of each solenoid 12 are attached to different arms of a lever 15, Fig. 2, each by a lost-motion connection, i.e. whilst pivoted on the same axis as the lever 15 are two further levers 17, each having one arm connected to a different one of the two extensions 13 and each of the other arms of levers 17 carrying a balancing weight. When the armatures are energized they move in opposite directions; should one solenoid fail the lost-motion connection enables the armature to remain stationary whilst the other solenoid effects actuation of the ball valve 3. The ball 3 is urged on to the tapered end of a resilient thin-walled alloy tubular seat 5 by a spring 4 and distorts the seat to ensure a good seal; the whole unit is replaceable upon removing a cap 35.

Title: Improvements in or relating to nuclear fuel compacts of coated particle fuel
Inventor: STURGE DEREK WILLIAM JAMES
IPC: B28B3/02
Filed: 1969-07-11
Abstract: 1282454 Fuel material UNITED KINGDOM ATOMIC ENERGY AUTHORITY 13 April 1970 [11 July 1969] 35156/69 Heading G6C A nuclear fuel compact comprises a plurality of fuel particles, each having a fission product retaining coating, distributed in a firm matrix material incorporating a polymerized bonding agent. It is formed by applying to each of a number of coated particles an overcoating of the matrix material with its bending agent in an unpolymerized condition, placing the particles in a die cavity with a layer of matrix material containing unpolymerized bonding agent disposed against at least some surfaces of the cavity, such that the coated fuel particles adjacent these surfaces are separated from them by a layer of matrix material of a thickness greater than that of the overcoating on these particles, pressing the particles in the cavity whilst heating them to melt the bonding agent and maintaining the pressure whilst further heating the cavity contents to polymerize the bonding agent. The layer of matrix material may be in the form of a preformed coupon placed on one or more surfaces of the die cavity to reduce the effect of particles protruding through their overcoating. In the preferred embodiment, an annular coupon was placed in the base of an annular cylindrical die cavity and a second annular coupon between the particles in the cavity and an annular punch inserted into the die. The coupons were of the same material as the overcoating, e.g. graphite powder in admixture with phenolformaldehyde resin. The contents of the die were raised to 100‹ C., at which temperature the resin was plastic and subjected to a pressure of 2000 p.s.i. Then the temperature was raised to 180‹ C., at this pressure, to polymerize the resin. The buffer layer of matrix material may alternatively be provided by an extra thick overcoating on those coated particles lying adjacent the die cavity surfaces, or it may be provided by a layer of microspheres of matrix material, without fuel, disposed adjacent the die vavity surfaces. As a further alternative, a layer of powdered matrix material may be placed between the overcoated particles and the surfaces of the cavity. In all cases the buffer layer incorporates unpolymerized resin bonding and becomes a part of the formed compact.

Title: Improvements in or relating to traffic control systems
Inventor: RANGE ALAN LESLIE
IPC: G08G1/08
Filed: 1955-12-09
Abstract: 803,916. Road signals for controlling traffic. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Dec. 3, 1956 [Dec. 9, 1955], No. 35334/55. Drawings to Specification. Class 118 (2). In a traffic signalling system arranged so that an extension of right-of-way is given to a vehicle approaching an intersection on a traffic lane already possessing right-of-way but that right-of-way is terminated after it has been given for a maximum period if it is required by another lane, and arranged so that the warning or amber signals on the two conflicting lanes are of fixed duration but capable of displacement in order to give a suitable clearance period, arrangements are provided whereby, if withdrawal of right-of-way is effected due to expiry of the maximum period, the amber displacement period is automatically increased or an amber displacement is introduced if the amber periods are normally concurrent, so as to give adequate clearance for the vehicle which is losing right-ofway. The facility provided by the invention is particularly necessary where a vehicle loses right-of-way on a maximum change immediately it has passed the road detector. Two arrangements are described. In the first, Fig. 1 (not shown), a fixed increase is made in the amber displacement. The system includes a timer circuit for the amber displacement utilizing the discharge of a capacitor to time the displacement and the arrangement operates to increase the resistance of the discharge path when a change takes place on maximum. In the second, Fig. 2 (not shown), the clearance period is variable depending on traffic conditions. The system again includes a timer for the amber displacement, but when a change takes place on maximum, although amber is displayed to the lane losing right-of-way, the start of the displacement timer is delayed until the full extension period applicable to the last vehicle to pass the road detector has expired. The effective displacement is thus increased and a vehicle always receives a clearance period equal to the sum of the whole of the extension period and the amber displacement period. It is stated that the amber displacement may be such that the two amber periods do not overlap and are separated by an all-red period. The normal amber displacement, i.e. for changes other than at maximum, may be reduced, possibly even to zero. Specification 725,475 is referred to.

Patent GB-808571-A (GB)
Title: Improvements in or relating to polyurethanes
IPC: C08G18/12
Filed: 1955-12-12
Abstract: A process for the production of polyurethanes from polyesters modified by isocyanates and cross-linking agents for the modified polyesters, comprises mixing at most 50 per cent by weight of the modified polyester with the amount of the cross-linking agent necessary to react with all of the modified polyester, said cross-linking agent being a polyfunctional compound containing active hydrogen atoms, thereby forming a cross-linking mixture and then mixing the last-mentioned material with the remainder of the polyester.  By the phrase "polyesters modified by polyisocyanates" is meant a rubber-like material produced by the action on the polyesters of an excess within the region of 20-250 per cent by weight of diisocyanates so that polyesterurethanes of various chain lengths with isocyanate groups in the end-position result.  Advantageously a plasticiser, e.g. dibutyl or dioctyl phthalate, hydrocarbons, diacetin or dicresyl glyceryl ether monoacetate, is added to the reactants employed in the formation of the cross-linking mixture. The reactions may also be effected with the reactants dissolved or dispersed in, for example, ethyl acetate or methylene chloride. Suitable fillers are soot, chalk, aluminium hydroxide, aluminium silicate or calcium silicate, silicic acid, powdered glass, glass fibres and asbestos fibres.  In examples the modified polyester is a product prepared by reacting an hydroxy adipic acid/ethylene glycol polyester with excess 1,5-naphthalene diisocyanate.  A portion of this product is reacted with excess 1,3-butanediol (in amount sufficient to react with all the modified polyester) to give the cross-linking mixture, which is then stirred into the hot, main quantity of modified polyester.  In examples: (3) and (5) dibutyl phthalate, diacetin and dicresyl-glyceryl ether monoacetate, respectively, are added to the cross-linking mixture; (4) the final reaction is effected in ethyl acetate or methylene chloride, to give a coating composition; (6) the products obtained in examples 1 to 3 are mixed with 10 to 15 per cent of a dried filler, comprising soot, silicic acid, powdered glass, glass fibres and asbestos fibres, respectively.  Specifications 700,608 and 700,610 are referred to.
