Patent GB-816853-A (GB)
Title: Improvements in or relating to the manufacture and treatment of porous rubber and like materials
Inventor: EVERETT LILIAN FRANCES
IPC: B29C67/24
Filed: 1954-12-21
Abstract: Resilient foam material suitable for upholstery is prepared by foaming a liquid natural or synthetic rubber mix containing ungelatinised starch, setting the foam to a self-supporting cellular mass having interconnecting cells without heating sufficiently to gelatinise the starch, and thereafter heating the mass to gelatinise the starch.  To a latex mix containing vulcanized, unvulcanized, or partly vulcanized natural or synthetic rubber, and desired compounding ingredients, may be added an ungelatinized aqueous dispersion of starch, the amount of starch thus added being 1 to 8 per cent. by weight of the total p  solid content of the mix.  The mix may then be foamed and gelled by freezing and treating with carbon dioxide gas, or by adding a delayed action setting agent, e.g. sodium silico-fluoride.  The starch is then gelatinised with swelling and bursting of the starch grains by heat applied during the initial stage of the vulcanizing, or drying operation.  In an Example a mix comprising 5 parts by weight of a 35 per cent. aqueous dispersion of maize starch, 100 parts 60 per cent. centrifuged unvulcanized latex, and vulcanizing and other ingredients is gelled by freezing and passing carbon dioxide therethrough.  The gelled mass is then heated to gelatinize the starch and vulcanize the rubber by passing a liquid or gas therethrough at a temperature of 100 DEG C.  A foam material having a high resistance to compression is produced. This resistance may be increased by a further treatment of the foam material by the method described in Specification 816,854 [Group IV(a)].

Title: A cable-hauled rail vehicle incorporating a safety brake
IPC: B61H9/02
Filed: 1964-09-11
Abstract: 1,070,296. Rope railways. SOCIETE DES FORGES ET ATELIERS DU CREUSOT. Sept. 11, 1964 [Oct. 4, 1963], No. 37354/64. Heading B7L. [Also in Division F2] In a safety brake of a cable-hauled rail vehicle system wherein the or each cable runs over a drive winch (not shown) at one end of the path and round a reversing wheel (not shown) at the other end of the path, cable ends 5a, 5b are coupled by fixed and movable spindles 7 and 10 respectively to a bracket 8 mounted on the vehicle 1, the latter spindle being urged to the right-hand end of a slot 11 under normal operating conditions against the bias of spring 13 on a rod 12, which is also pivoted on spindle 10, by tension exerted in the cable by a counterweight connected to the reversing wheel. As illustrated in Fig. 3 (not shown), rod 12 is mechanically linked by pivoted levers 17, longitudinal rods (20) and pivoted levers (23) to a spring-biased catch bolt (25) at each end of the vehicle, each bolt retaining a crossmember 30 bearing brake shoes 31. On failure of a cable, the spring 13 urges the rod 12 to the left and through corresponding movement of the linkage, disengages each catch bolt (29) from the associated cross-member allowing its free fall, the forwardmost member, with respect to the direction of motion, braking the vehicle by engagement of the shoes between wheels and rails. The cable and coupling arrangement is duplicated on either side of the vehicle to form a two-cable system, slots (20a) at the end of each longitudinal rod (20) permitting release of the cross-members regardless of which cable breaks. A simplified form of the brake can be used for a central, single cablehauled rail vehicle. Where vehicle axles are close together, the haulage cables may be connected to a cross-member carrying two double shoes disposed between the axles. If two haulage cables are used, the drive winches are driven through a differential so that, firstly the tension in each cable is the same, and secondly, on breaking of one cable, the other ceases to pull the vehicle.

Title: The production of hexafluoroacetone and perchlorofluoroacetones
IPC: C07C49/167

Abstract: A dichromium trioxide catalyst is made by precipitating hydrous chromic oxide from a solution of a trivalent chromium salt, e.g. by adding sodium or potassium hydroxide, or, preferably, ammonia gas or aqueous ammonium hydroxide, and subsequently heating it to 300-400 DEG  C. for not less than one hour.  For example, aqueous ammonia is added to a heated aqueous solution of Cr(NO3)3.9H2O to pH7, the solution is boiled and filtered hot, the precipitate hot water-washed and, dried by heating under vacuum or in an inert gas stream or in equipment with facilities for steam escape, at 100-200 DEG C.  The partially dehydrated oxide is granulated to 4-20 mesh or pressed to pellets 3 mm. x 10 mm. and subjected to heat treatment at 300-400 DEG C. for a substantial period. The heat treatment may take place in an atmosphere consisting of water vapour and optionally an inert gas for at least two hours. The catalysts are substantially amorphous and have a surface area at least 5m2/g and usually above 50m2/g. Specification 794,075 is referred to.ALSO:Hexafluoroacetone, perfluorochloroacetone or a mixture thereof is made by contacting in the vapour phase at least one perhalogenated acetone containing two to five fluorine atoms and no halogen other than chlorine and fluorine at an elevated temperature up to 500 DEG  C. with a dichromium trioxide catalyst obtained by precipitating hydrous chromic oxide from a solution of a trivalent chromium salt and subsequently heating it to 300 DEG -400 DEG  C. for not less than one hour.  The catalyst may be used in unsupported granular or pelleted form or supported on inert refractory material.  The preferred starting materials are perhalogenated acetones containing two to four fluorine atoms. The process may be operated continuously and the products separated by fractional distillation. In examples using sym-tetrafluorodichloroacetone, 1,1,2 - trifluoro - 1,2,2 - tricloroacetone or pentafluorochloroacetone, the main products were CF3COCF3, CF3COCF2Cl, CF3 COCFCL2 and CF3COCL3 with CF2ClCoCCL3 in addition in the first two examples.

A nuclear reactor core comprises a plurality of rotary fuel elements each having eccentric multiplying and non-multiplying regions (i.e. regions having infinite multiplication factors greater than unity and less than unity respectively) and being mounted for rotation to afford control of the reactor by the interchange of the positions of the multiplying and non-multiplying regions in the core. By way of example, the core of a fast fission reactor has seven fuel elements in the form of six drums 12 to 17 encircling a seventh drum 11, each of the outer drums being rotatable about its longitudinal axis and comprising distinct semicircular sectors 18, 19. The sectors 18 include natural uranium fuel enriched in the fissile 235-isotope and act as the multiplying regions while the sectors 19 contain a predominance of fertile material, e.g. the 238-isotope in natural uranium which has been depleted in the fissile 235- isotope, and act as the non-multiplying regions. The central fuel drum 11 is stationary. A reflector structure 20, e.g. iron or graphite bricks, or, alternatively, a fertile material, fills the outer interstitial spaces between the drums while the inner interstitial spaces afford locations for the insertion of conventional control rods 21 or further fertile material.
