Patent GB-754798-A (GB)
Title: Sizing textile yarn and the like
IPC: D06B3/18
Filed: 1954-08-09
Abstract: <PICT:0754798/IV(c)/1> A process for sizing yarn comprises squeezing it in the dry state then without exposing it to the air drawing it under tension through a size bath and squeezing it again before withdrawal from the bath.  Fig. 1 shows a textile treating apparatus in which yarn is to be passed through a sizing bath 1 the yarn passing over roller 32 and being squeezed between feeding roller 31 and bath roller 2.  It then passes through a trough of liquid formed between bath roller 2 and sinking roller 4 into the bath and out between rollers 5 and 3.  A tension measuring device 30 applies a differential control to the drive to rollers 2 and 2 so that the tension in the yarn is maintained at a pre-determined value.  The sinking rollers 4 and 5 are connected by a toggle linkage 6, 7 to an operating member via a hydraulic or pneumatic system 15, 16 and 17, 18 so that the sinking rollers 4, 5 may be raised entirely out of the bath at the end of a treatment process, and the pressure between squeezing rollers 2, 4 and 3, 5 respectively adjusted, if necessary unequally, in dependence upon a number of variable influences.  The bath rollers 2 and 3 can be moved in a substantially horizontal plane.  In a modification.  Figs. 2, 2A (not shown) the roller 32 of Fig. 1 is dispensed with.

Patent GB-920012-A (GB)
Title: Selective hydrogenation and catalyst therefor
IPC: C07C7/167
Filed: 1959-07-08
Abstract: Highly unsaturated hydrocarbons such as acetylenes and diolefins in gas mixtures containing high concentrations of olefins are subjected to selective hydrogenation by passing such a mixture at a temperature in the range 100 DEG -400 DEG F. and at an hourly space velocity of 300-1,600 under a catalyst which comprises palladium metal deposited on an alumina carrier, and which has a pore volume of surface pores with a threshold diameter not exceeding 800  in the range of between 0,0 and 0,4 c.c./gm., the palladium being concentrated predominantly on the external surface of the alumina carrier.  The catalyst may be obtained by spraying a palladium salt solution on to an alumina carrier having an appropriate initial pore volume of surface pores and pores of appropriate threshold diameter as indicated above. Preferably the palladium salt is applied so as to produce a catalyst containing 0,01-0,09% of palladium.  A solution of palladium nitrate or chloride may be used.  The impregnated catalyst may be calcined and subjected to reduction with hydrogen prior to being used in the selective hydrogenation of olefin mixtures.  The catalyst may be regenerated by steaming.  In an example, a dry gas containing mainly propylene with propadiene, nitrogen, propane, and hydrogen is passed over the prepared catalyst so as to remove the propadiene by selective hydrogenation.  Another example describes the treatment of a mixture containing ethylene, methane, propylene, acetylene, and hydrogen, to remove the acetylene by selective hydrogenation.

Abstract: 1381565 Storage systems P KOCH 17 May 1973 [19 May 1972 (2) 11 April 1973] 23616/73 Heading B8E  In a storage system comprising compartments 4 having supports 27 on which the edges of pallets 5 are supported, and an elevator 3 having a platform 3a which carries a device for inserting pallets into, or removing them from, the compartments, the platform 3a is flanked by boards 96 for receiving pallets from the device, and the device comprises a jib 6 which can be extended into a compartment 4 and is composed of telescopic members 7-9 each of which comprises a pair of trolleys 10 adapted to run on rails 28 in the compartment and having parts 31 which can be raised to lift a pallet from the supports 27. Each trolley has a frame 29 supported by rollers 30 and supporting rams 33 which carry the part 31. The frames 29 are formed with guides 22, 23 adapted to interengage when the members 7-9 are extended or retracted, the members being interconnected by electromagnetic couplings 40-42 when they are extended. The two trolleys 10 of the member 9 are interconnected by cross-bars 11, 12 formed with guides 17, 18. The ends 19 of a lazy-tongs linkage 39 are engaged in the guide 18, the other ends 47 of the linkage being engaged in guides 48 on the platform 3a. The piston 52 of a cylinder 54 on the platform engages a bush 53 on the linkage 39 to extend or collapse the linkage and thus the jib. If the jib is to be extended to the other side of the platform to that shown in Fig. 3, the ends 19 of the linkage 39 are engaged in guides 65 on the platform 3a, and the ends 47 of the linkage are engaged in the guide 17 on the member 9, the piston 68 of a second cylinder 67 being engaged in a linkagebush 51 adjacent the ends 19. In operation, the jib is extended and the pallets in a compartment are lifted from the supports 27. The jib is then retracted until the member 7 is positioned on the platform and the pallets on the member 7 are lifted by rollers 99, which are raised by rams 61 on the platform, and the pallets are pushed on to the boards 96. The coupling 42 is released and retraction continued until the member 8 is positioned on the platform for unloading. The coupling 41 is then released and the member 9 is retracted on to the platform. In other embodiments (Figs. 12-16), the trolleys are driven by gears carried by a drive shaft on the platform and engaging racks on the trolleys or are driven by rams connected between respective trolleys, the parts 31 extend below the supports and both have cut-outs to permit raising of the parts, and the boards 96 carry sets of rollers for handling the pallets.

Title: Improvements in and relating to the manufacture of electrical contacts

Filed: 1953-08-27
Abstract: 749,390. Making electrical contacts. MALLORY METALLURGICAL PRODUCTS, Ltd. Nov. 12, 1954 [Aug. 27, 1953], No. 23694/53. Classes 83 (2) and 83 (4). Powder metallurgy.-In a method of making an electrical contact, a powder compact having a facing layer in which precious metal predominates and a backing layer of a base metal is sintered to form a composite contact piece which is then subjected to a pressing operation to extrude a shank or riveting portion from the backing layer. In a modification a composite sintered strip is formed and the contact pieces are punched from the strip and then pressed to extrude the shank portion. In an example 700 grams precipitated silver powder and 300 grams carbonyl nickel powder were mixed in a porcelain mill for 6 hours and screened through a 60 mesh sieve. To make a single contact piece 0.013 grams of the mixture was placed in a die of 0.182 inch diameter on top of the same weight of electrolytic copper powder of between 100 and 300 mesh. The double layer was then compressed to a density of 7.5 grams/cc. to produce a compact 0.080 inch thick which is sintered at 750‹ C. in cracked ammonia for 15 minutes. Instead of a single compacting step, the powder may be lightly pressed, sintered at 800-900‹ C., repressed and resintered at a temperature below 780‹ C. The sintered contact piece is then pressed to extrude the shank portion. Specification 642,648 is referred to.

Title: Epoxidation process
Inventor: RUSSELL JOSEPH LEE
IPC: C07D301/19
Filed: 1965-06-03
Abstract: Epoxy compounds are prepared by reacting an olefinically unsaturated compound with a hydroperoxide of an aralkane, having at least one hydrogen atom on a carbon atom adjacent to the aromatic ring, in the liquid phase in the presence of a metal epoxidation catalyst, the amount of hydroperoxide employed being 0.1-1.0 mol per mol olefinic groups and the reaction being continued until hydroperoxide conversion is at least 95%.  It is preferred to continue the reaction until hydroperoxide conversion is at least 98%.  The preferred epoxidation catalysts are V, W, Mo and Se, particularly compounds thereof which are soluble in the reaction mixture, e.g. carboxylates. Preferred hydroperoxides are those of cumene and ethyl-benzene. Specified olefinic reactants include olefins, alcohols, esters, ethers, ketones and organic halides.  The preferred olefinic group: hydroperoxide ratios are in the range 2:1 to 5:1. It is preferred to operate at - 10 DEG  C. to 175 DEG  C. in the presence of an organic solvent.  In the course of the reaction, the hydroperoxide is reduced to an alcohol having the same carbon skeleton.  This alcohol can be recovered and reacted with hydrogen to effect reduction to the corresponding hydrocarbon which on reaction with molecular oxygen yields the hydroperoxide which may be recycled.  Examples relate to the preparation of propylene oxide using cumene hydroperoxide, which is prepared by oxidation of cumene.  Cumyl alcohol is obtained as a by-product.
