Title: Improvements in machines for cutting insole and sole blanks for use in the manufacture of boots and shoes
IPC: C14B5/00
Filed: 1934-08-15
Abstract: 422,692. Cutting-machines. COMPO SHOE MACHINERY CORPORATION, 565, 5th Avenue, New York, U.S.A. Aug. 15, 1934, No. 23584. Convention date, May 29. [Class 31 (i)] A machine for cutting complementary insoles and outsoles from a single rounded blank, Fig. 9, comprises feeding and guiding means for the blank, and a cutting device 18, Fig. 10, which starting from a preformed slash A, continues a split B and also extends the cut to the surface of the blank so as to leave the part D integral with the outside. The knife has cutting edges 21, 22 at right angles to one another. Feeding and guiding means are shown generally in Fig. 1. An operator takes the sole blank previously slashed and split and by means of a treadle connected to a rod 56 elevates the feed apparatus pivoted at 44 so as to insert the work beneath a feed wheel 57. The knife 18 is inserted in the split B at the slash A while the blank is positioned against an edge gauge 69. The treadle is released and a spring 51 clamps the feed wheel 57 against the blank. The operator pulls a handle 36 in a clockwise direction, Fig. 6, causing a lever 34 to pivot at 35 so that a wedge face 37 forces a constantly rotating pulley 24 against a friction wheel 26, Fig. 1. This drives the shaft 29 and feed wheel 57 which directs work to the knife. The handle 36 rotates in the grasp of the operator only as long as required. The knife 18 can be adjusted by screws 15, 19 in a head 10. A presser foot 58 lies behind the feed wheel 57 and is adjustable on a strap 43 by a screw passing through a slot 60 and a vertical adjusting screw 61 which has a flange 62 slidable in a groove in the upper end of the presser foot. A circular work support 63 is arranged beneath the feed wheel and knife and has a spindle 64 running on a ball race. The upper end of a bushing 65 includes a projection 68 affording a mounting for an edge gauge 69. Vertical adjustment of the support is possible by a screw 73. The work contacting portion of the gauge is located almost opposite, but preferably a little in advance of, the axis of the work support, while the knife edge at 21 is positioned just beyond this axis. This effects almost automatic positioning of the work. U.S.A. Specifications 1,838,708 and 1,902,725 are referred to.
Patent GB-599336-A (GB)
Title: Improvements in or relating to the separation and purification of diolefins
IPC: C07C7/148
Filed: 1945-09-14
Abstract: In a process for separating diolefins from mixtures of C5 or C6 hydrocarbons containing also acetylenes by contacting with ammoniacal cuprous salt solutions, a solution is used containing at least 1 gram mol. per litre of copper and at least 0.5 gram mol. of ammonia or an amine in excess of that required to solubilize the copper, the amount of solution being sufficient to dissolve only the acetylenes.  A C5 or C6 cut may be extracted with aqueous acetone, for example, to give a diolefin, for example isoprene, containing 1-2 per cent of a -acetylenes which is then treated by the process, for example with a cuprous solution of 3 molar copper, 4 molar ammonium acetate, and 7 molar ammonia content using 1 volume of solution to 2 of hydrocarbon. For isoprene extraction, suitable temperatures are 70-150 DEG  F. Extraction of a C6 diolefin such as methyl pentadienes-1,3 may be effected in liquid phase at 0 DEG  C.  The solubilities of diolefins and acetylenes in cuprous solutions of various composition, including cuprous acetate-ammonia, cuprous sulphate - pyridine, and cuprous chloride - monoethanolamine solutions, are given.  The solution containing acetylenes may be heated to polymerize the latter, if desired after adding to a solution used in butadiene separation according to the process of the parent Specification.  Piperylene, and 2,3-diimethylbutadiene are other diolefins specified.
Patent GB-501805-A (GB)
Title: Improvements in the production or treatment of pigments and textile and other materials containing them
IPC: D06M11/46
Filed: 1937-09-01
Abstract: 501,805. Artificial filaments, films, etc.; treating textiles with liquids; dyeing processes ; pigments; metallic oxides &c. ELLIS, G. H., and STANLEY, E. Sept. 1, 1937, No. 23923. [Classes 2 (ii) and 15 (ii)] [Also in Group III] A product suitable for use as a pigment in artificial silk, films, moulded articles, and the like is obtained by a process wherein titanium dioxide is associated or treated with a compound of a metal of Group V, subgroup A, of the Periodic Table, at normal or moderately elevated temperature only. The titanium dioxide may be in a textile material, film, or moulded article. The presence of a compound of vanadium, tantalum, or similar element counteracts the tendency for artificial silk delustred with titanium oxide to lose strength when exposed to light, and for dyeings on such materials to fade. The titanium dioxide may be associated with a copper compound together with the vanadium compound The vanadium compound may be incorporated with titanium dioxide before or after the latter is incorporated in the artificial silk and before or after dyeing. It may be incorporated in the solution from which filaments or films are obtained. Vanadium trichloride, ammonium vanadate, or other salts may be used in the form of dilute aqueous solutions containing, if desired, formic, acetic, or other organic acid. The titanium dioxide in finely divided form may be heated or boiled with a solution of a vanadium salt. The treatment may be such that an oxide, hydroxide, or other water-insoluble compound of vanadium is fixed on the titanium dioxide or material containing it. The vanadium compound may be directly mixed with the titanium dioxide. The fastness of water-soluble azo dyes on regenerated cellulose, or soluble or insoluble azo dyes on cellulose acetate when these materials contain titanium dioxide, is improved by the process. The process may be used in association with the dyeing of cellulose acetate materials containing titanium dioxide, with aminoanthraquinone dyes, e.g. 1À4-diamino or 1À4-amino-oxy-anthraquinone or their substitution products, or with indigoid dyes, or waterinsoluble azo dyes produced on the fibre, e.g. those produced by coupling diazotized amines with #-naphthol, arylamides of 2À3-oxy-naphthoic acid, or diacyl-acetyl derivatives of aromatic diamines. In an example, finely divided titanium dioxide is heated at 85-90 C. with a solution of ammonium vanadate and formic acid in water, filtered, washed, dried, and incorporated in a cellulose acetate spinning solution. In another example, a cellulose acetate fabric of low lustre due to the presence of titanium dioxide is treated with a hot solution of ammonium vanadate and formic acid in water. Specification 475,356 is referred to.
Patent GB-705489-A (GB)
Title: Improvements in or relating to protein-containing materials suitable for use in foodproducts
IPC: A23J3/32
Filed: 1949-09-19
Abstract: Protein-containing materials are treated to remove objectionable tastes and smells by a process which comprises degrading the material by subjecting it to hydrolysis at elevated temperature by subjecting it to hydrolysis at elevated temperature in aqueous alkaline solution or suspension until the viscosity of a 10-15 per cent. aqueous solution of the hydrolysed material has become approximately equal to that of water at the same temperature, the measured viscosity of the solution being less than 10 centipoises, treating an aqueous solution of the degraded material in known manner with activated carbon and filtering the solution thus treated.  The initial aqueous solution or suspension can contain up to 5 per cent. or more by weight of an alkali, such as caustic soda, caustic potash or sodium carbonate. After hydrolysis the excess alkali may be neutralized by means of a mineral acid such as hydrochloric acid or an organic acid such as acetic acid or citric acid.  The hydrolysis is usually carried out by heating the aqueous alkaline solution or suspension under reflux if preferred at a temperature in the range 50-100 DEG C. or, if desired, under pressure at a temperature up to about 140 DEG C.  In the examples (a) commercial fish albumen is mixed with water and the resulting paste heated and treated with caustic soda, the heating is continued until the viscosity falls to below 10 centipoises, the solution is neutralized with hydrochloric acid, treated with activated carbon and filtered to give a clean odourless solution which can be used to replace egg albumen in food products; (b) oil-free fish meal is heated with water and hydrochloric acid is added, the mixture is neutralized with caustic soda and washed; the washed damp meal is then treated as in (a); (c) commercial peanut protein powder is treated as in (a). Specification 501,630, [Group IV], is referred to.ALSO:Protein-containing material, which has been subjected to a treatment including degrading it by hydrolysis at elevated temperature in aqueous alkaline solution until the viscosity of a 10-15 per cent solution is less than 10 centipoises, treating an aqueous solution of the degraded material with active carbon and filtering the resultant mixture, may be used as a foaming agent suitable for use in sweet food product.

Title: Improvements in shock absorber for vehicles
IPC: F16F7/04
Filed: 1925-10-05
Abstract: 241,540. Eclipse Machine Co., (Assignees of Lansing, R. P.). Oct. 16, 1924, [Convention date]. Vibration-dampers. - In a vehicle vibrationdamper of the rebound type having a differential or one-way action, a pressure member is adapted to apply greater or less pressure to frictional elements according to whether it is rotated in one direction or the other. The apparatus is constructed in two main parts, one part being connected to the. frame and consisting of a plate 1 with securing bolts 3 and a spindle 6 fixed in the plate and supporting, slidably but non-rotatably, a threaded sleeve 40. Teeth 43 on the sleeve 40 engage corresponding teeth in the extension of the plate 1. The other main part consists of a hollow casing in several parts 10, 18, 22, 28 bolted together, the part 18 being formed with the operating arm 17 connected to the axle. The friction elements consist of discs 25 alternately connected to the part 22 and to the pressure member 50 which is threaded to engage the sleeve 40. When the arm 17 and connected parts are moved in one direction, the pressure member 50 is screwed up the sleeve 40 until the clearance 42 is taken up and the two are locked together. Further rotation of the pressure member is thus prevented and it forces the friction discs together with the full pressure of the helical spring 70 acting on the flanged washer 75. When the arm 17 is moved in the opposite direction, the pressure member is screwed down the sleeve 40 until the pressure on the friction discs is relieved and slipping takes place. When this action occurs, the sleeve 40 abuts against a distancemember 45. A small amount of free movement is thus allowed before the friction discs act. An oil-retaining washer 14 is interposed between the relatively moving surfaces to prevent escape of grease or oil from the casing.
