Abstract: 483,212. Lubricating. SULZER FRERES SOC. ANON. Sept. 29, 1937, No. 26344. Convention date, Oct. 19, 1936. [Class 12 (iii)] [Also in Groups XXIX and XXVI] In an internal-combustion engine, a pump 21, Fig. 1, draws from a sump 18, into which used lubricating oil drains, and delivers through a pipe 22, a pressure-responsive valve 23, and a cooler 26 into a chamber 10 from which the lubricating pump 8 draws. The cooler 26 is provided with a byepass 76 controlled by a manually-operated valve 25, the pipe having a restriction 77 such as to ensure that the resistance to flow through the pipe 76 approximates to that through the cooler. Alternatively, a thermally-actuated valve may be provided to regulate the flow through the cooler and byepass so as to maintain a constant temperature of the oil. Thus, as shown in Fig. 2, a double-valve 86, 87 is connected to a rod 80 arranged in a casing, the rod having a greater coefficient of expansion than the casing. Springs 85, 88, arranged as shown, allow further expansion or contraction of the rod 80 after the valve 86 or 87 is fully closed.

Title: Improvements in or relating to the separation of at least one constituent from a gaseous mixture
Inventor: FABRE CLAUDE
IPC: C01G43/06
Filed: 1960-08-03
Abstract: A process for the continuous separation of one or more constituents of a gaseous mixture containing at least one sublimable material, in particular uranium hexafluoride, consists in cooling an initial gaseous current of the mixture to cause the formation within the current of crystals of the one or more constituents to be separated, separating the crystals from the other non-condensed constituents, contacting the crystals with a surface which is sufficiently hot to cause at least partial sublimation thereof, and recovering the one or more constituents formed during the sublimation separately from the other non-condensed constituents. The cooling may be effected by adiabatic expansion for example in a turbine. The separation of the crystals may be effected by means of a cyclone. Fig. 2 shows an apparatus for effecting the purification of uranium hexafluoride, and Fig. 3 is a detailed view of the subliming cyclone. Thus, in Fig. 2, uranium hexafluoride vapour enters at 1, passes through turbine 2 and expansion chamber 3, where UF6 crystals are formed, the suspension thus formed being passed to cyclone 4 where the crystals are separated and sublimed, pure UF6 exiting at 6. In Fig. 3, the suspension enters at 13. The walls of the cyclone are heated by hot fluid circulating in double wall 16 subliming the cake of UF6, crystals 19 deposited on the wall of the cyclone, the vapour thus formed exiting at 14. <PICT:0956278/C1/1> <PICT:0956278/C1/2>

Title: Improved method of coating polytetrafluoroethylene
Inventor: CROZE MARTIN W
IPC: D06Q1/04
Filed: 1954-09-20
Abstract: A firmly bonded metallic coating is formed on a surface of sintered polytetrafluoroethylene by depositing, from the vapour state in vacuo, a metallic coating, non-fusing at the sintering temperature, on the unsintered material, and then sintering the polytetrafluoroethylene without fusing or oxidizing the metallic coating.  Materials, e.g. adhesives, electrical insulating waxes and resins, varnishes and labels, normally non-adherent to polytetrafluoroethylene may be bonded thereto by metal coating the surface and then bonding the material to the metallized surface. Examples describe (a) the metallizing of a thin self-supporting extruded polytetrafluoroethylene film oriented in the direction of extrusion by depositing gold in vacuo, heating in air to a sintering temperature of about 450 DEG C. and finally quenching in water and (b) coating a film as in (a) with copper followed by sintering in vacuo.  Additional metal may be added as by electroplating.  The copper coating may be removed from specified areas by chemical action or electrical discharge in order to produce printed circuits, condenser elements and test electrodes. Alternatively the metal vapour may be applied initially through screens or masks or portions of the metal coating may be removed before sintering.  Other metals that may be applied include nickel, silver and aluminium and the coatings may be further treated, e.g. aluminium may be anodized. Bodies of polytetrafluoroethylene other than films may be coated, e.g. electrical conductors, such as copper cables, wires, or coils, which have been covered with a layer of unsintered polytetrafluoroethylene, may be provided with a thin conductive metal sheath, and the polymer then sintered.  It is stated that the invention is equally applicable to co-polymers of tetrafluoroethylene with small amounts of other copolymerizable monomers.  Reference has been directed by the Comptroller to Specification 686,031.
