Title: Improvements in nuclear fuel elements
IPC: G21C3/18
Filed: 1961-05-29
Abstract: 918,224. Nuclear fuel elements. GENERAL DYNAMICS CORPORATION. May 29, 1961 [June 8, 1960], No. 19363/61. Class 39 (4). A nuclear fuel element comprises a solid fuel body 23 and cylinders 27 of moderator material enclosed in a sheath 7 having a cylindrical sidewall 9 and closed by top and bottom end fixtures 11, 13 respectively the fuel body 23 having tapered ends and a polished surface. The inner surface 31 of the sheath 7 is also smooth so that there is little frictional contact at the interface of the fuel body and sheath. The top end fixture 11 and the adjacent cylinder 27 are separated by a small expansion gap which also extends between the sidewall 9 and cylinder 27, wafers 25 of burnable poison are disposed on either side of the fuel body 23, and a hightemperature lubricant 33, e.g. colloidal graphite or molybdenum disulphide, is disposed between the sidewall 9 and the fuel body 23. A suitable taper for a fuel body 23 having a length of 14 inches is 0.025 inch over a distance of 2 inches at each end and the surface irregularities should have an average height reduced to within the range 10 to 20 micro-inches. A suitable fuel comprises a homogenous mixture of 8% wt. U-238 (enriched to 20% U-235) and 92% wt. zirconium hydride (moderator material) and the sheath 7 is formed from annealed aluminium. Beryllium, beryllium oxide, graphite or other moderator can be used for the cylinders 27. The combination of the taper, polish, lubrication, expansion gap and use of annealed aluminium substantially reduces the tendency of the sheath to irreversibly elongate and crack.

Abstract: 1,249,690. Galvanic cell. HELLESENS A/S. 17 April, 1969 [18 April, 1968], No. 19625/69. Heading H1B. A galvanic cell which comprises a metal can closed by a lid-formed contact member embedded in insulating material is characterised in that the insulating sealing material and the said lid are attached between the bent edge of the metal can and a ring-formed or disc-formed supporting member which may be of'metal or plastics and which is fixed along its periphery to the can wall. In one embodiment the cell construction is identical to that of Fig. 2 of the copending application 19624/69 in which the supporting member is ring-shaped and is attached to the inner side of the metal can. In another embodiment, Fig. 2, the supporting member is a flat diaphragm 14 which is integral with and forms the bottom of a canformed top part 15. The top part 15 with contact member 7 and sealing material 16 may be made as a prefabricated unit which is joined to the upper edge of can 17 after the electrically active material has been deposited in the can, for example, by welding or gluing in combination with an outer clamping ring 18. Diaphragm 14 has a hole to permit insulated passage of a connecting member between one of the cell electrodes and contact 7.

Title: Improvements in or relating to the decarburizing of iron and steel and their alloys
IPC: C21C7/00
Filed: 1929-06-26
Abstract: 314,439. Siemens & Halske Akt.-Ges. June 27, 1928, [Convention date]. Cementation; purifying and refining. - In a process for decarbonizing iron or steel by heating to a red heat or melting in an atmosphere of hydrogen, the pressure in the chamber in which they are heated is about 100 atmospheres. The temperature used may be 1000‹ Celsius and the walls of the chamber may be kept at a low temperature. The chamber may comprise an airtight crucible of ceramic material which is heated by high frequency current or electric resistances. The hydrogen is blown into the material continuously and the methane formed during the process removed by treatment outside the chamber, e.g. by selective absorption media, the introduction and removal of the gases forming part of a closed cycle of circulation. After the process is finished, the hydrogen is withdrawn by a pump, the chamber evacuated and the iron heated to a high temperature to expel any occluded hydrogen. The cooling down of the iron after the treatment may take place in a vacuum. Specifications 260,646 and 317,180 are referred to.

Title: Method of repairing or retreading vehicle tyres

Filed: 1975-05-12
Abstract: 1482504 Retreading or repairing tyres VAKUUM VULK HOLDINGS Ltd 12 May 1975 [13 May 1974] 19919/75 Heading B7C A method of effecting a local repair in a tyre or of retreading the whole or a portion of a tyre comprises placing a flexible cover 3 over the area to be repaired or over the tread region after the damaged area has been filled with unvulcanized bonding rubber or an unvulcanized bonding rubber layer 10a has been placed between the tread or tread portion and tyre carcass, sealing the edge(s) of the cover to the tyre by employing an adhesive 14, evacuating the region beneath the cover and/or applying pressure to the outer surface of the cover and heating the region to vulcanize the rubber filling or layer. The adhesive may be vulcanizable at the temperature required to vulcanize the rubber filling or layer, e.g. bonding rubber or non-vulcanizable, e.g. PTFE, or bonding rubber minus vulcanizing agents. The sealing may be effected to each side of the tyre, where the tyre is being retreaded, by a ring 15 coated with adhesive 14 or having the adhesive on one or two sides of the ring. A vacuum can be induced via pipe 6 and pressure and heat or heat alone may be applied in an autoclave, the medium for heat and pressure or heat alone being water, steam, hot air or a mixture of steam and air. The adhesive may be applied as a strip or in liquid form, and it may be necessary to roughen the tyre to promote adhesion of the cover to the tyre. If portions of the cover edge(s) remain adhered to the tyre after cover removal, those portions may be ground away. To enable easy removal of the cover, the tyre portion, which is to receive the adhesive, is first coated with silicon. When effecting a local repair the rubber filler may be vulcanized by heating elements in the cover.

Fig. 1 shows a block provided with two partitions 5, 5 which form plaques D, D<1> Fig. 2, additional to the plaques A, B, C, A<1>, B<1>, C<1>, formed from the sides of the block. The portions 6, 6 which connect the sides 2, 4 with the partitions 5, 5, and the other pieces of the block not shown in Fig. 2, are discarded when the block is split up. The plaques A, A<1> &c. are formed with dovetailed grooves 10, 10 &c. and the surfaces e, g, e<1>, g<1>, &c., at which the plaques were severed from the blocks are disposed away from those edges of the plaques that are to be juxtaposed when the plaques are assembled in use. For supporting the blocks on a flat surface during drying the surface 3 is provided with ribs 3a. An alternative construction is described in which the partitions 5, 5 are formed parallel with the sides 2, 4, and the block may be split into fourteen plaques.

[Class 39 (i).] The amount of caesium in the oxide coated cathode of a photo-electric cell is regulated by introducing into the tube an excess of caesium and absorbing that not required in the coating by means of lead oxide or other absorbent material which is supported within the tube and to which heat can be supplied. Potassium, sodium, rubidium or other alkali metal may be used instead of caesium and silver oxide or copper oxide may be used as absorbents. A photo-electric cell may be made by providing an evacuated tube with an anode of nickel and a cathode consisting of a metal plate having a coating of silver which may be electrodeposited. A part of the wall of the tube is painted with a paste of lead oxide and amyl acetate or the oxide may be deposited on a filament that can be heated or on a metal body which can be heated by induction. Oxygen is introduced into the tube and the silver coating on the cathode oxidized by a discharge. An excess of caesium is then placed in the tube which is heated to 200‹ C. Some of the caesium combines with the silver oxide coating, the excess of caesium being absorbed by the layer of lead oxide.
