Title: Improvements in and relating to the treatment of copper alloys
IPC: C22F1/08
Filed: 1921-04-09
Abstract: 161,537. Isabellen-H³tte Ges. April 10, 1920, [Convention date]. Alloys.-Relates to the heat-treatment of copper alloys containing manganese and small amounts of aluminium, zinc, tin or silicon, and consists in subjecting the alloys, after they have been cast, rolled or forged, to a prolonged heating at a temperature below red heat. In an example an alloy consisting of 10-15 per cent manganese, 10-15 per cent aluminium, the remainder being copper, is improved by heating to a. temperature of 220‹ C. for 20 hours. The treatment is stated to render the metal suitable for the manufacture of knives. A marked hardening effect takes place in the case of brass alloys containing a high proportion of manganese. Such an alloy containing 51 per cent copper, 40 per cent zinc and 9 per cent manganese after rolling at a high temperature, forging and annealing at 600‹ C. and cooling shows a tensile strength of 54 kilogrammes per square millimetre, extension 11 per cent and a Brinell hardness of 166. After heating for 36 hours at 230‹ C., the same alloy shows a tensile strength of 60 kilogrammes per square millimetre, extension 2 per cent and a Brinell hardness of 260. Manganese, silicon and copper alloys hardened by this method at temperatures of 200 to 400‹ C. may be used in place of tin alloys for heating liners. Other examples are given in the Specification.

Title: Improvements in disc brakes
Inventor: SPENCE PETER
IPC: F16D65/14
Filed: 1964-03-14
Abstract: 1,099,402. Disc brakes. DOWTY TECHNICAL DEVELOPMENTS Ltd. March 12, 1965 [March 14, 1964], No. 10912/64. Headings F2E and F2F. A spot-type disc brake comprises at least one piston-and-cylinder hydraulic device of the two-stage type in which an increased hydraulic pressure acting on a first-stage piston is generated by a second-stage differential piston. As shown, brake pads 14, 15 are moved into contact with a brake disc 16 by hydraulic pressure from a master cylinder 36 acting on first-stage pistons 17 against tension springs 20. At low pressures, the hydraulic fluid passes directly to spaces 25 behind the first pistons through passages 33, 34, past ball valves 28 which are held open by rods 29 secured to a common casing 18, and through bores 26 in second-stage pistons 21. When the pressure increases further the second-stage pistons are deflected against compression springs 30, enabling springs 31 to close the ball valves, thus interrupting the direct fluid connection between the master cylinder and the spaces 25. Further increase in fluid pressure moves the second-stage pistons 21 further inwards, moving piston-rods 23 into the spaces 25 and thereby the pressure in the spaces 25 to increase more rapidly than the master cylinder pressure due to the difference in area between each piston 21 and its piston-rod 23. In another embodiment (not shown), a single piston and cylinder may operate a floating-calliper type of disc brake.

Title: Improvements in or relating to carbonaceous materials of low permeability and their manufacture
Inventor: BEAN LEONARD WILLIAM
IPC: C04B35/528
Filed: 1963-03-21
Abstract: Materials substantially impermeable to gases, composed of carbon having an inorganic substance other than free carbon dispersed therein, are produced by forming a dispersion of cellulosic or hemicellulosic material in an aqueous liquid in which dispersion the initial fibrous structure of the said material has been broken down to form small, hydrated, fibrous particles, regenerating said material from the dispersion by removal of the free water, drying the regenerated material to remove the bound water of hydration therefrom, impregnating partially regenerated (i.e. a dispersion containing at least 10% by volume solid material) or regenerated, or dried material with the said inorganic substance or with a compound from which said substance is derived on heating, and heating the dried, impregnated material slowly to at least 1350 DEG  C. to effect carbonisation and render the carbon so formed substantially impermeable to gases.  The inorganic substance may be a metal, say uranium or thorium, free or in the combined state e.g. as oxide or carbide, or a non-metal excluding free carbon.  The impregnation step may be carried out by mixing the partially regenerated cellulosic, or hemicellulosic material, with the powdered, inorganic substance or compound, or by soaking the regenerated or partially regenerated or dried material in an aqueous solution of a water-soluble salt, e.g. uranyl acetate or nitrate, at ambient or increased temperature.  The initial, aqueous dispersion containing say 2% by volume of solid material is centrifuged to a pulp which is then mixed with water to form a stiff paste and cast into a brass tube with nickel gauze and filter paper fitted over the end.  The filled tube is enclosed in a vacuum vessel the pressure being reduced to 4-5 cms. mercury and the pulp tamped down during and after evacuation.  The residual, stiff, pulp is dried in an oven at 70 DEG  C. to a rigid rod which is machined into pieces of the required shapes and these pieces are soaked in the impregnating solution for the required length of time. The impregnated pieces are dried at ambient temperature and subjected to carbonising heat treatment wherein the material is baked slowly at up to 300 atmospheres pressure in nitrogen or inert gas atmosphere to 350 DEG  to 420 DEG  C. and then heated under atmospheric pressure in an inert atmosphere to 1350 DEG  C. to 1500 DEG  C., further treatment at higher temperatures e.g. a graphitizing temperature of at least 2100 DEG  C., being optional.  The uranium or thorium containing carbonaceous materials produced above are advantageously used as fuel elements in nuclear reactors.
