Title: Improvements in sterol derivatives and process of making same
IPC: C07J9/00
Filed: 1938-03-04
Abstract: 509,063. Sterol derivatives. PARKE, DAVIS, & CO. March 4, 1938, No. 6840. Convention date, March 12, 1937. [Class 2 (iii)] A process for preparing 7-hydroxy-cholesteryl halides comprises reducing a 7-keto-cholesteryl halide compound. The hydroxy compound may be treated with an acylating agent to obtain an ester. Thus, 7 - keto - cholesteryl chloride is obtained by treating cholesteryl chloride in acetic acid with chromic oxide in water and glacial acetic acid, and adding ethyl alcohol. The product is reduced by dissolving in glacial acetic acid and shaking with hydrogen under 45 lbs. pressure in the presence of platinum oxide, to give a crystalline precipitate of alpha-cholestyl chloride and a mother liquor containing 7-hydroxy-cholestyl chloride. Crude 7-hydroxy-cholestyl chloride in dry boiling amyl alcohol is treated with sodium to give cholestanol-7. Cholestanone - 7 is obtained by treating 7-hydroxy-cholestane in acetic acid with chromic oxide in acetic acid. 7-Hydroxycholesteryl chloride is obtained by adding aluminium isopropylate to a solution of 7-ketocholesteryl chloride in dry isopropyl alcohol. The benzoate is obtained by shaking 7-hydroxycholesteryl chloride in dry pyridine with benzoyl chloride.

Abstract: 1406317 Heat treatment of metals STANDARD TELEPHONES & CABLES Ltd 4 Oct 1973 [11 Oct 1972 13 Feb 19731 ] 46781/72 and 6943/73 Heading C7N [Also in Division H5] In apparatus for the thermal conditioning of wire of the type in which wire 1 is passed over two or more electrically conductive pulleys, 2, 5, 6 via which heating current is supplied to the wire, that part 20 of each pulley which makes contact with the wire 1 is made of or faced with a contact material having a melting point not less than 1200‹C. Suitable materials are two-phase tungsten-copper and tungsten-silver materials, tungsten, tantalum and their carbides. Where only a surface layer is provided this layer may comprise chromium, a cobalt alloy containing chromium tungsten and optionally molybdenum, or a boride, nitride or carbide. Pulleys 2 and 6 are connected to the earthed side of supply 9 and pulley 5 to the live side so that no extraneous current is supplied by supply 9 to the wire 1 before pulley 2 or after pulley 6. The section of wire 1 between pulley 2 and pulley 5 is greater than that between pulley 5 and pulley 6 so that the first section acts as a pre-heater and the second section as an annealer. The pulley 6 is cooled by an air or water jet to reduce the plasticity of the wire at this point. The invention may also be applied to apparatus for thermal conditioning previously annealed wire prior to applying electrical insulation. Copper, aluminium, nickel and tinned copper wire may be treated. Each pulley comprises a high melting point contact tyre 20 removably mounted on a two-part pulley 21, 22. The pulley rotates in a low friction precision ball journal type bearing 24 or an air bearing. Current is supplied by means of a carbon brush 25 biased against a boss 27 on the pulley. Alternatively, Fig. 3 (not shown), the boss has a circumferential flange which dips in molten metal in a heated vessel.

Abstract: In the ammonia-soda process, ammonia and carbon dioxide are employed under pressure, preferably in the liquid condition, and the low temperature produced by their expansion is utilized to cool the reaction liquors.  The heat absorbed by the expansion of ammonia and that absorbed by the expansion of the carbon-dioxide are utilized in the absorbing and carbonating towers respectively. After passing through the expansion valves and cooling coils, the carbon dioxide is advantageously diluted to the extent of 40-45 per cent, with nitrogen in order to moderate the reaction.  The nitrogen is supplied under pressure and preferably in "pulses," and is collected for re-use after passage through the carbonating-towers.  Specification 131,870 is referred to.  The Specification as open to inspection under Sect. 91 (3) (a) states also that the carbon dioxide may be used to cool the absorbers.
