Abstract: 1,171,739. Microporous rubber articles with foam core; solid tyres. CONTINENTAL GUMMI-WERKE A.G. 20 Sept., 1968 [22 Sept., 1967], No. 44926/68. Heading B5A. [Also in Division B7] Articles e.g. tyres of rubber or synthetic elastomer with a porous core and a microporous outer layer, the outer layer comprising <SP>1</SP>/ 10 -<SP>2</SP>/ 3 of the radial cross-section, are made from a mixture of elastomer and blowing agent. A mould of volume 10-20% less than that of the desired article is filled with a blank of elastomer-blowing agent mixture. After closing the mould it is heated so that the outer layer of elastomer is cross-linked and the core and blowing agent are unaffected. The partially cross-linked blank is removed from the mould and heated again to decompose the blowing agent and cross-link the rest of the elastomer. The resulting article has a foamed core, and a transition zone of decreasing porosity leading to the outer layer in which the bubbles are not visible to the naked eyes. Non-porous areas may be provided in the outer layer of the article by incorporating sections of elastomer without blowing agent in the mould, these sections being no thicker than the thickness of the outer layer in the formed article. The process can be used to make tyres for vehicle wheels, caterpillar track guide wheels and and rollers.

Title: Improvements in or relating to subhallide distillation process for the recovery of aluminium
IPC: C22B21/00
Filed: 1963-11-22
Abstract: Phosphine together with methane is produced by treating with water the residue produced by extracting aluminium in a converter using the sub-halide process.  The residue is passed from converter to treatment zone without intermediate exposure to the atmosphere and the gases evolved are withdrawn from the treatment zone.  A suitable apparatus is shown in the Figure where residue from converter 10 is discharged from 22 into an enclosed hammer mill 23, where the residue is comminuted to pass through screen 23-preferably 0.25 inch mesh. From 23 it falls into hopper 27 which narrows to form tube 30 of diameter at least 8 times greater than the maximum diameter of the particles.  Tube 30 when filled with particles <PICT:1028375/C1/1> forms a dust seal between the converter 10 and the quench tank 47 and inhibits the passage of gas between them.  The particles pass from 30 through conveyer 36 and fall into water contained in tank 47.  The temp. of the mix produced is maintained at 30 DEG  C. by suitable addition of water by pipe 53 and withdrawal of slurry via pipe 52 into the stripper tank 57 which is supplied with steam by pipe 58 to heat the slurry and drive off all the evolved gases through vent 61. If the residue contains only a slight amount of aluminium, the amount of gas evolved may be only small, and the use of the stripper tank unnecessary.  The venting of gases from tank 47 through pipe 54 is subject to the control of system 72, which is set to equalize the pressures between the ends of the dust seal column 31.  This serves to reinforce the efficiency of the seal in inhibiting the transfer of gas between the quench tank and the converter.  The level of particles in 27 is monitored by sensing device 44 which controls the speed of transporting screw 35 so as to maintain the residue level constant and thus maintain the efficiency of the dust seal.  The gases evolved from the treatment zone are usually phosphine and methane produced by the action of water on the AIP and the A13C4 content of the residue. The phosphine may be oxidized to phosphoric acid.

Abstract: 1358336 Heat exchangers GULF OIL CORP 10 Oct 1972 [28 Oct 1971] 46649/72 Heading F4A A heat exchange arrangement comprises a plurality of tubes for fluid to be heated arranged as an assembly of coaxial helical coils in a flow of heating fluid; the tubes being linked in pairs at one end of the assembly and means being provided at the other to introduce fluid under pressure into one tube of each pair and to receive heated fluid from the other. In the arrangement shown the helically arranged heat exchange tubes 13 are employed in the reheater of a steam generator associated with a gascooled nuclear reactor. The steam generator 39 receives primary gas, helium or carbon dioxide, through duct 43 from core area 33, and the gas generates steam in tubes 63 before being returned to the core through duct 45. Steam for reheat is passed into inlet tubes 105, which constitute half of the tubes 13, and at the end of the tubes remote from the inlet passes through linking sections 21 into the remainder of the tubes to travel back to the outlet tubes 107. As shown there are even numbers of coaxial coils and pairs of coils are linked by the sections 21. In an alternative embodiment (Figs. 3, 4, not shown) each coil has an even number of tubes and pairs of tubes in the same coil are linked. In the steam generation section, feedwater enters at 57 and passes through tubes 61 arranged between double walls 17 to steam bundle 63 which constitutes a combined evaporatoreconomizer and superheater arrangement; steam then passing via tubes 65 down cylinder 67 to outlet 71. Heating gas moves from inlet 43 down over the tubes 13, which are arranged between walls 17 and 19 then up the duct formed between wall 19 and the cylinder 67. At the top of the assembly the gas is diverted by wall 89 down over the tubes 63, then is drawn around the lower edges of shell 81 and up over the outside of the shell by gas circulator 41; moving into duct 99 which communicates in an upper region (not shown) with the outlet duct 45.
