Title: Improvements in or relating to steroid derivatives
Inventor: PHILLIPPS GORDON HANLEY
IPC: C07J75/00
Filed: 1958-08-08
Abstract: The invention comprises P1p2-bis-steroid 21-pyrophosphates and salts thereof, the steroid being additionally characterized by a D 4- or D 1,4-double bond or bonds, 3- and 20-keto groups, an 11b -hydroxy or 11-keto groups and a 17a -hydroxy group; and their preparation by (1) de-aralkylation of an appropriate P1P2-bis-steroid diaralkyl pyrophosphate with an alkali metal halide in an organic solvent, to give a dialkali metal salt of the required pyrophosphate; or (2) condensing 2 molecules of a corresponding orthophosphate or a mono-sodium salt thereof in the presence of a carbodiimide R7N:C:NR8 (R7 and R8 being alkyl, cycloalkyl, aryl or aralkyl groups) or of cyanamide or a mono- or dialkylcyanamide.  Suitable alkyl halides for use in process (1) are sodium iodide and lithium chloride, and the process may be combined with the preparation of the diaralkyl pyrophosphate starting material by condensing 2 molecules of a corresponding steroid 21-aralkyl hydrogen phosphate (obtained by acidification of a corresponding salt thereof) in the presence of one of the condensing agents referred to above or by condensing an appropriate 21-halogeno steroid with a P1P2 diaralkyl disilver pyrophosphate.  The steroids of the invention may also contain 2- and/or 6-and/or 16-alkyl substituents, and/or 9-halo substituents, and/or a 6-fluoro substituent, and/or a 16-hydroxy or -acyloxy substituent, and they may form salts with, for example, alkali or alkaline earth metals, ammonia or organic bases such as N,N1-dibenzylethylene-diamine, the last named type of salts being prepared either from the free pyrophosphate and the free organic base or from an alkali metal or ammonium salt of the pyrophosphate and a salt of the base.  Examples illustrate the compounds of the invention and their preparation by the above processes, and reference is also made to the conversion of corresponding pyrophosphates having a different steroid moiety, e.g. a saturated ring A, to the pyrophosphates of the invention, which have adrenocortical activity. The steroid pyrophosphates of the invention may be made up into pharmaceutical compositions with suitable carriers or diluents. These may take the form of solutions, tablets, capsules, syrups, elixirs, ointments, lotions, suppositories, or aerosols.  In the Provisional Specification 21-pyrophosphates of steroids containing additionally or alternatively a saturated ring A, a D 5-double bond, no 11-substituent and no 17-substituent or a 17-acyloxy group are also referred to, and the pyrophosphate derived from pregnan-21-ol-3,20-dione and its alkali metal salts, which are intravenous anaesthetics, is stated to have improved solubility. De-aralkylation of diaralkyl steroid pyrophosphates by hydrogenolysis and treatment with anhydrous tertiary amines is also referred to. Specification 902,225 is referred to.

IPC: F28B1/02
Filed: 1921-09-30
Abstract: 169,977. Ginabat, A. Oct. 5, 1920, [Convention date]. Surface condensers.-In the various groups of tubes in a condenser, zones such as h, i, k are formed with tubes j, through which passes water or liquid cooler than that passing in the surrounding tubes, so as to cool air collecting therein and to lead the air to the pump outlet J. These zones are preferably in the middle of the banks of tubes separated by steam channels c, d, e, g. The liquid supplied to the tubes j may be specially cooled and passes by way of subsidiary headers m, n, p, within the main headers F, G, and in the case of water may join the main circulation at the outlet H. If there is no special cool water available the water flowing through the tubes j is kept at a lower temperature than that in the other tubes by making the tubes j of larger cross-section with or without subsidiary headers s, t, u, Fig. 6, extending into the upper part of the condenser. The spaces x, which would ordinarily have no tubes owing to the position of the division plates a, b in the headers, are filled by dummy tubes.

Title: Improvements in or relating to flexible abrasive articles and methods of making the same
IPC: B24D11/00
Filed: 1945-10-08
Abstract: Aqueous emulsions of polyvinyl resins produced by emulsion polymerization are used for impregnating the absorbent backing of a flexible abrasive article.  In examples: (1) a wetting agent such as sodium lauryl sulphate, ammonium persulphate, and triethanol-amine are dissolved in water and mixed with an aqueous solution of polyvinyl alcohol.  The mixture is cooled to 52 DEG  C. and a mixture of monomeric vinyl acetate, methyl methacrylate, diamyl fumarate, and di-isoamyl ethylene di-fumarate is added while allowing the temperature to rise to 71 DEG  C. from which it is gradually increased to 84 DEG  C., the pH value being maintained between 4 and 5 by slight additions of triethanolamine.  A small amount of octyl alcohol may be added as a foam depressant; (2) as in (1) except that the mixture of monomers consists of methyl acrylate, vinyl acetate, and di-isoamyl ethylene di-fumarate; (3) as in (1) but omitting methyl methacrylate from the mixture of monomers; (4) benzoyl peroxide is dissolved in methyl acrylate and the resulting solution stirred into a heated aqueous solution of wetting agent and hydrogen peroxide; (5) vinyl acetate, formic acid, and ammonium persulphate are added to an aqueous solution of polyvinyl alcohol, and the mixture is heated to 72 DEG  C. so that refluxing takes place.  When refluxing stops, the temperature is allowed to rise to 81 DEG  C., after which the resulting emulsion is cooled.  Specifications 633,012 and 651,321 are referred to.  The Specification as open to inspection under Sect. 91 comprises also the use of an emulsion made by working until smooth a heated mixture of polyvinyl butyral resin, coumarone resin, tricresyl phosphate, and oleic acid, adding water a little at a time, adding potassium hydroxide solution until the emulsion inverts to a resin-in-water one, and diluting with water.  This subject-matter does not appear in the Specification as accepted.
