Title: Improvements in or relating to the treatment of artificial silk
IPC: D01D10/04
Filed: 1931-01-01
Abstract: <PICT:0369675/IV/1> <PICT:0369675/IV/2> <PICT:0369675/IV/3> For the treatment of artificial silk cakes with washing, desulphurizing, bleaching, soaping, or dyeing liquids, or with drying air, the cakes are superposed and arranged in column formation with a separating member between each two cakes in a column, and treating fluids are passed transversely through the cakes.  The separating member comprises a base upon which the cake rests and an upstanding portion having a continuous peripheral wall which is perforated and extends into the interior of the cake.  The height of the upstanding portion is less than that of the cake to be supported upon the base of the separating member, and its diameter is preferably less than that of the adjacent portion of the bore of the cake.  Fig. 1 shows a hollow separating member 10 made of aluminium sheet and comprising an annular base 11 with a cylindrical skirt portion 12 and a conical portion 13. The conical portion is perforated.  A number of holes 16 are provided in the base 11 adjacent the wall 13 for drainage purposes.  Alternatively, the upstanding portion may be cylindrical. Fig.3 shows a separating member 10 made of porcelain.  The separating member may be made of steel lined with ebonite, of "Bakelite," rubber, or absorbent textile material. Fig. 5 shows a treating apparatus in which the separating members are employed.  A number of cakes 17 are superposed in columns with a separating member 10 between each two cakes in a column.  The cake columns are arranged in a receptacle 18 having vertical side and end walls 20.  A framework structure 25 is detachably bolted to the flanges 21 of the receptacle 18.  This frame-work supports and maintains the outer columns of cakes in an upright position. The cakes are subjected to compression by means of a weighted board 28.  The weights 29 are selected according to the pressure desired.  The board is counterbalanced by weights 30.  Liquid is supplied under pressure to the trough 24 from which it passes through perforations 33 into the interior of the cake columns, through the perforated walls of the separating members 10 and through the cake material.  When the liquid passes through the cakes they expand therefore against a resistance and any subsequent contraction when the liquid ceases to pass through is assisted. Specifications 297,118, 319,766, [Class 2 (ii), Cellulose &c.], and 358,151 are referred to.  The Provisional Specification comprises also the step of rotating the cakes to assist the penetration of the treating fluids.

Title: A rotary electric switch with resilient contacts
IPC: H01H1/06
Filed: 1957-01-01
Abstract: 840,322. Switch contacts ; mechanical switches, without quick-action. TESLA NARODNI PODNIK. Jan. 1, 1957, No. 98/57. Class 38 (5). In a rotary switch, some of the contacts are formed by U-shaped wire springs which are arranged with their bends disposed towards the axis of rotation and their legs extending towards the periphery of the switch. In one form, Figs. 3, 6 and 8, a rotatable disc 1 carries wire contacts 2, the ends of which are sprung into conical holes 11 and cemented in place. The stator 3 has a circular flange with radial slots 32, 33 and a central aperture 30 with radial grooves 31. The U-shaped contacts 4 are fixed with their bends in grooves 31, their free ends 42 in slots 32 and their parts 43 in slots 33 where they are cemented at 34. The parts 43 are bent to form loops and the free ends are also located in slots 33, their springiness helping to fix the contacts. The contacts 2 are aligned as shown in Fig. 8 so that upon rotation, the point of contact F moves along the contacts 4. In a modification, Fig. 10 (not shown), the moving contacts are formed by segment-shaped foils secured to the surface of the disc 1. Contacts may be arranged on both sides of disc 1 to cooperate with two sets of fixed contacts, and several switches may be assembled on a common spindle, Fig. 12 (not shown), the U-shaped springs may be on the rotatable member.

Title: Improvements in or relating to the synthesis of hydrocarbons and oxygenated organic compounds
IPC: C07C1/02
Filed: 1948-01-07
Abstract: In the synthesis of hydrocarbons and oxygenated compounds by passing a feed gas containing H2, CO and CO2 upwards through a zone containing an iron catalyst, chiefly of about 1-200 micron particle size, at a temperature of at least 550 DEG  F., and a pressure above 150 p.s.i., to maintain a dense phase fluidized condition, the H2 : CO : CO2 ratio in the total feed is 2-6 : 1 : 1-3, and the quotient of mol. per cent H2 X mol. per cent CO2 over (mol. per cent CO)2 is about 3-9.  The amount of CO should be about 8-15 mol. per cent, although only about 2 per cent may be present when starting up with active catalyst.  The synthesis gas may be obtained by reaction of methane and about 10 per cent excess oxygen at about 200-300 pounds per square inch, and at least 2200 DEG  F. to yield a gas with a H2 : CO ratio of 1.8-2 : 1.  By addition of CO2 and other diluents or by recycling of tail gas, the H2 : CO : CO2 relationship is adjusted to within the required limits.  The preferred catalyst is made by heating ferric oxide to incipient fusion and reducing with hydrogen and contains 1-2 per cent potassium.  The reactor (see Group III) may have an upper enlarged settling chamber and cooling means comprising vertical tubes arranged about 3 inches apart over the cross-sectional area, closed at their bases, and open at the tops to receive concentric open tubes to which cooling fluid is supplied.  About 5-15 cubic feet CO per hour is introduced per lb. of catalyst.  Cooling or diluent liquid such as hydrocarbons may be sprayed into the dense phase at different heights in the form of fine drops or cooling gas may be introduced.  Catalyst may be recirculated from the upper levels to the feed gas by a stand-pipe.  The product is fractionated to yield a gasoline which is contacted with silica-alumina or bauxite at 200-1000 DEG  F., and up to 50 pounds per square inch, space velocity 2-20, to improve the O.N. and convert oxygenated compounds to hydrocarbons.  Reference has been directed by the Comptroller to Specification 664,346.ALSO:<PICT:0655454/III/1> A reactor for the synthesis of hydrocarbons from H2, CO and CO2, using a fluidized iron catalyst comprises an enlarged upper settling chamber with cyclone separators 63, 65 within and/or outside it, a series of concentric tubes 47, 49 spaced about 3 inches apart over the cross-sectional area and fed with cooling fluid from reservoir 51 and vessel 53.

The cationic surface active agent may be N-alkyl-diamines, N-alkyl-triamines, N-alkyl oxypropyl-diamines, N-alkyloxypropyl-triamines, N-alkyl B amino propionic acids, N-alkyl oxyproply-B amino propionic acids, alkyl quaternary ammonium compounds, alkyl oxypropyl quaternary ammonium compounds, alkyl diethanal benzyl quaternary ammonium compounds, N-B alkyl amidoethyl-ethylene amines, N-alkyl-N-ethyl-ethanal amines, 1-ethyl, 2-alkyl imidazalines.  The cationic surface active agents may be in the form of soluble salts.  Specific cationic surface active agents are listed.  The alkyl radicals may be those obtained from coconut oil, tallow, soybean oil, tall oil and other triglycerides. Either the anodic passifier or cathodic passifier may be admixed in liquid form with the granular salt.  The salt may be mixed with the anodic passifier and an anti-caking agent such as sodium ferrocyanide added to the dry mixture, an aqueous solution of the cathodic passifier then being sprayed on to the mixture which is suitably agitated to insure even distribution and then dried by heating in an oven or storing in an area of low humidity to produce a granular, free flowing salt.  A dispersing agent may be included in the sprayed cathodic passifier, and also a dye.  The salt may be sprayed with an aqueous solution of both the anodic and cathodic passifier, or the cathodic passifier added in dry form and the anodic passifier sprayed, or all the chemicals added in dry form.
