Title: Improvements in and relating to the production of saturated and unsaturated devivatives of pregnane dione
IPC: C07J75/00
Filed: 1940-09-05
Abstract: 544,484. Derivatives of pregnane dione. ORGANON LABORATORIES, Ltd. Sept. 4, 1940, Nos. 13879 and 13880. Convention dates, Sept. 7,1939, and Jan. 9, 1940. Addition to 502,289. [Class 2 (iii)] 3-Hydroxy-21-diazo-pregnane compounds are oxidized in a neutral medium to the corresponding 3-keto compounds. The preferred oxidizing agent is a carbonyl compound in the presence of an aluminium alcoholate. The ring system may contain as additional substituents o-alkyl, o-aralkyl, o-acyl or oxygen groups, and it may be saturated or unsaturated. If in addition to the 3-hydroxyl group, other hydroxyl groups are present, these may also be oxidized to keto groups. In examples (1) 21-Diazo-pregnene-5-ol-3-one-20 is oxidized in benzene solution with acetone in the presence of aluminium tertiary butylate. (2) 21- Diazo-pregnene-5-ol-3-one-20 are treated with the same reagents as in example (1) under slightly varying conditions. In each case 21-diazo-progesterone is produced. Specifications 487,360 and 500,767 are referred to. The Specification as open to inspection under Sect. 91 includes also examples describing the preparation of 21-chloro-progesterone by the action of dry gaseous hydrogen chloride in ether on 21-diazo-progesterone, the treatment of 21-diazo-progesterone with dilute sulphuric acid to give desoxycorticosterone, with glacial acetic acid to give desoxycorticosterone acetate, with benzoic acid to give desoxycorticosterone benzoate, with anhydrous phosphoric acid to give desoxycorticosterone phosphate.

Title: Improvements in Buffers for Railway Vehicles and the like.
Inventor: WATSON CECIL
IPC: B61G11/18
Filed: 1917-09-29
Abstract: 119,510. Pawsey, R. F., and Watson, D. C., (Executors of Watson, C.). Sept. 29, 1917. Buffers.-Relates to spring buffers of the eelfcontained type in which a plunger works in a casing having an internal shoulder adapted to be engaged by a stop or retaining-device on the outer surface of the plunger to arrest the recoil. According to the invention, the retaining-device is applied to the plunger from the inside and is arranged to project through the walls of the plunger so as to contact with the casing shoulder. In the construction shown in Figs. 3, 5, 6, and 7, the retaining-device is in the form of a split ring a lying in a groove b<1> in the plunger b and having parts a<1> projecting through slots b<2> in the plunger to engage the shoulder c' of the casing c. The projections a<1> preferably engage grooves c<3> in the casing to prevent rotation of the plunger, and may be formed separately from but attached to the split ring a instead of integral therewith. The ring may be prevented from collapsing by a projection on the plunger entering the opening in the ring. In the modification shown in Fig. 9, the projections are in the form of blocks d pressed outwards either by means of a split ring e or by a split tubular sleeve, the blocks d being capable of passing freely through the slots b<2> or, as shown, being prevented from so doing by means of lugs d<1>. The retaining-device can be applied to the plunger either before or after the latter is inserted in the casing. In the former instance, it is preferable to taper one edge d<3> of the blocks as shown in Fig. 12, so that they cause the ring e to collapse when the plunger is forced into the casing. In order to allow the buffer to be dismantled, threaded holes g may be provided in the casing c through which a set-screw h can be passed to collapse the split ring or sleeve.

Title: Improvements in or relating to the production of skins or tubes
IPC: A22C13/00
Filed: 1936-05-22
Abstract: <PICT:0471566/IV/1> <PICT:0471566/IV/2> Ring-shaped tubes, particularly for sausage casings are made by extruding a plastic kneadable fibrous mass of animal origin through an annular nozzle whilst blowing gases into the interior of the tube being formed, and withdrawing the tube helically. The fibrous mass is extruded through the nozzle 1 (Fig. 1) and the tube is passed helically around the series of rollers 5 within the drying channel.  The rollers 5 are driven from the central shaft 7.  A suitable extrusion nozzle is described in Specification 433,245.  In order to produce tubes of uniform wall thickness, a tube is formed by extrusion through an annular nozzle with an eccentrically-disposed core, and the tube is withdrawn so that the thickened part of the wall lies on the outside of the helix. Again, the fibrous mass may be extruded through an annular nozzle having a bevelled orifice, with or without rotating parts, and the curved tube thus formed withdrawn helically.  The tubes, after drying, may be rendered resistant to boiling by treatment with water-displacing or tanning agents, e.g., aluminium sulphate, alumina, tannin or products of the slow combustion, distillation or carbonization of cellulose-and lignin-containing products.  The protein-containing fibrous pastes employed as starting materials may be obtained from hide, de-tanned leather, sinews, muscles, flesh and the like by loosening or disintegrating and afterwards mechanically comminuting or shredding.  The Specification as open to inspection under Sect. 91 describes also an extrusion device consisting of pots 2 and 3, Fig. 1 (Cancelled), mounted on the framework 1 and capable of being brought alternately into operative position on the table of the press 6.  The fibrous mass is forced into the cylinder 17 which serves as a supply chamber and buffer. Pressure is maintained in this cylinder by means of the press 18. From the cylinder 17 the mass is fed alternately into the high pressure cylinders 27 and 28, which force it into the annular nozzle 37, consisting of a stationary part 36 and a rotatable core 38.  Air is blown in through the hollow axle 40.  This subject-matter does not appear in the Specification as accepted.

Abstract: 440,026. Proofing fabrics and paper against liquids and fire. BRICK TRUST, Ltd., 1, London Wall Buildings, London.-(Assignees of Leroy, (nÚe Ombredane), Y. A. R. ; 31, Rue Magenta, Asnieres, Seine, France). May 15, 1934, No. 14630. Convention date, May 16, 1933. [Classes 96 and 140] Fibrous materials such as paper, pasteboard, and fabric are rendered impervious to liquids and fireproof by first impregnating the material with an insoluble salt of a higher fatty acid, for example by treatment successively with the soluble salt of the fatty acid and a metallic salt which will precipitate the fatty acid, then treating the impregnated material at a temperature of 30 to 75‹ C. with a fireproofing solution and with a solution of gelatine or other albuminoid substance which is hardened, for example with formaldehyde. A higher fatty acid is defined as an acid derived from an oil or fat the salts of which form soaps, e.g. stearic and oleic acids. For the first impregnation an aqueous solution of stearic acid and alkali carbonate may be used, followed by zinc sulphate solution. The fireproofing agent may be made by mixing a solution of sodium tungstate, borax, tri-sodium phosphate and ammonium phosphate with a solution of phospho-triamide made by dissolving phosphorus oxychloride in aqueous ammonia. Gelatine solution is added to this mixture. The treatments may be effected by dipping or spraying and the material may be pressed or dried after each impregnation ; or paper may be treated in pulp form. The product may be used for making receptacles such as boxes, containers, bottles, pots, tubes and sacks, garments, gloves, and packing materials.
