Title: Improvements in electrodes for electro-chemical devices
IPC: H01M4/86
Filed: 1963-11-25
Abstract: A fuel cell electrode has its metallic catalyst partly coated with copper, silver, cadmium, mercury or a mixture or alloy of these metals. The catalyst may be Raney Ni, Fe or Co.  A bi-porous double-skeleton Raney nickel electrode was coated with copper by precipitation from copper nitrate and heating to 80 DEG C.; with mercury by precipitation from mercury nitrate and heating to 100 DEG C.; with silver by precipitation from silver nitrate or with cadmium by precipitation from cadmium nitrate.  The electrode may be in the form of Raney nickel particles coated with mercury (by dipping in mercury and squeezing to remove excess) or copper disposed between metal sieves. The coating may be formed electrolytically.  The catalyst may contain a promoter e.g. platinum, palladium, iridium, rhodium, chromium, tungsten or molybdenum.  In one Example 1 part of a Raney alloy comprising 50% wt Al, 25% wt Fe and 25% wt Ni, was compressed with 0.65 parts of carbonyl nickel and 0.65 parts of carbonyl iron prior to sintering in hydrogen at 700 DEG C.  The sintered body was then immersed in a 6N KOH solution containing 1% Seignette salt.  After twenty four hours mercury nitrate was added and the partial coating was completed at boiling point.

Filed: 1973-10-09
Abstract: 1443470 Prosthetic implant SULZER BROS Ltd 9 Oct 1973 [26 Oct 1972] 47106/73 Heading A5R A prosthetic implant comprises a socket 6 which is adapted to be anchored in a bone 1 e.g. a finger bone and a bone replacement member having an articular surface (not shown) and including a shank 4 which is releasably inserted in said socket 6. The socket, of a plastics material, such as polyester or polythene, and the bone replacement member, an alloy, are correspondingly tapered, the tapered shank 4 fitting into a blind tapered hole 5 in the socket 6. Owing to the shapes of these members the implant when assembled requires a minimum force which is greater than the normal loading in use to separate the members. A slot 8, formed at the outer end of the socket 6 receives a corresponding portion 9 of the shank to prevent rotation of the bone replacement member relative to the socket. In an alternative embodiment, the bone replacement member and the socket 6 may both have uniform circular or elliptical cross sections. The socket 6 is secured in the bone by means of bone cement 7 e.g. methyl methacrylate, the outer surface then being grooved, or alternatively the outer surface may be porous, enabling the living bone tissue to grow thereinto.

Title: Solvent dewaxing of mineral oil

IPC: C10G73/06
Filed: 1970-10-09
Abstract: 1,267,464. Solvent dewaxing mineral oils. TEXACO DEVELOPMENT CORP. 9 Oct., 1970, No. 48064/70. Headings C5E and C5W. In the separation of wax from mineral oils using a dewaxing solvent comprising an aromatic hydrocarbon and a ketone cooling of the solvent-oil mixture at a rate of 1-30‹ F. per minute is effected by mixing a liquid refrigerant with the mixture at a pressure sufficient to maintain the refrigerant in the liquid phase and then reducing the pressure to vaporize the refrigerant with concomitant cooling of the mixture and crystallization of the wax. A lube oil feed, e.g. a solvent refined vacuum distillate, is mixed with a liquid refrigerant 53, e.g. ammonia, propane or chlorofluorocarbons, and a dewaxing solvent 51, e.g. a mixture of toluene and methyl ethyl ketone, and the mixture is heated to 130‹ F. at 54 to effect complete solution and then cooled to 110‹ F. at 56 by indirect heat exchange. The mixture is then passed into one of the crystallizers 60a, 60b, 60c and 60d, e.g. 60a, and the pressure is reduced via one of the valves 63a, 63b, 63c and 63d to an intermediate pressure and then through one of the valves 76a, 76b, 76c and 76d to the final low pressure. The refrigerant vapour inline 78 at low pressure is compressed at 85 to the higher pressure of the refrigerant vapour in line 69, the two vapour streams are combined and compressed at 71 and cooled at 73 for recycle as stream 53. The cooled wax-oil-solvent mixture from the crystallizers is filtered at 89. The slack wax is washed, then repulped with additional solvent and filtered at 100, again washed and the solvent is stripped from the deoiled wax. The dewaxed oil stream 90 is stripped at 91 and the wax stream 105 is stripped at 106 to provide vapour streams 92 and 107 which are condensed and recycled as the solvent stream 51. The four crystallizers 60a, 60b, 60c and 60d are arranged so that the overall effect is to carry out the functions of filling, first and second stage cooling and emptying continuously.
