Patent GB-707733-A (GB)
Title: Preparation of steroid compounds
IPC: C07J75/00
Filed: 1949-10-25
Abstract: 12-Hydroxysteroids having a double bond in the 9,11-position are manufactured by reducing the corresponding 12-ketosteroids with hydrogen in the presence of a hydrogenation catalyst and a catalytic amount of a mineral acid, in solution in a lower (1-6 C) aliphatic alcohol.  The process is applicable in particular to the reduction of 3-hydroxy-D 9,11-12-ketocholenic acid, or a lower (1-6 C) alkyl ester prepared therefrom by the action of the lower aliphatic alcohol and mineral acid prior to the addition of the hydrogenation catalyst, to a lower alkyl ester of 3 - hydroxy - D 9,11 - 12 - hydroxycholenic acid, which may then be converted to the corresponding 12-lower alkoxy ester by treating it, after removal of the hydrogenation catalyst, with a lower aliphatic alcohol in the presence of mineral acid. Advantageously the hydrogenation catalyst is of the noble metal group and the mineral acid is a hydrogen halide or sulphuric acid. In examples: (1) 3 - hydroxy - D 9,11 - 12 - ketocholenic acid is allowed to stand at room temperature with methanol and a trace of aqueous hydrochloric acid, the resulting solution of the methyl ester is shaken with hydrogen in the presence of platinum oxide catalyst, the latter is removed by filtration, and the product is allowed to stand at 0 DEG  C. with additional methanolic hydrochloric acid, yielding methyl 3-hydroxy-D 9,11-12-methoxycholenate; (2) the initial period of standing for the esterification of the keto-acid is omitted.  The Specification as open to inspection under Sect. 91 comprises the reduction of any unsaturated ketosteroid to an unsaturated hydroxysteroid by the above method.  This subject-matter does not appear in the Specification as accepted.

Title: New biologically active substance from urine or suprarenal glands and a process for its manufacture
IPC: A61K31/573
Filed: 1957-08-30
Abstract: The invention comprises a sublimable, crystalline substance, m.p. 258-60 DEG , having the effect of eliminating sodium from the human or animal organism, and its preparation by separating by further distribution chromatography and/or with the aid of carboxyl reagents the amorphous fractions remaining after the almost complete separation of the known steroids from extracts of urine or suprarenal glands, and isolating the active substance in crystalline form from the biologically active fractions or the carbonyl portion.  In examples, extracts from urine or adrenal, glands are purified by distribution and adsorption chromatography, the remaining amorphous fractions subjected to paper chromatography, e.g. using formamide/benzene-chloroform or propylene glycol/toluene or benzene-ligroin-methanol-water and the product preferably further purified with Gignard T reagent to yield the carbonyl containing active substance.ALSO:Pharmaceutical compositions for restoring a disturbed sodium balance contain as active principle a sublimate, crystalline substance C21H34O3, melting-point 258-260 DEG  C. (having the effect of eliminating sodium from the human or animal organism, and isolated from urine and suprarenal glands), together with a solid or liquid carrier.  The active substance is substantially free from other active compounds occurring in urine and suprarenals, and is administered by enteral, parenteral or topical methods, e.g. in the form of aqueous or oleaginous solutions, suspensions, emulsions, implantates, tablets, dragees, salves or creams.  The compositions may include auxiliaries, e.g. preserving, wetting, stabilizing, emulsifying and buffering agents and other therapeutic compounds. Examples 4-6 detail specific compositions.

Title: Improvements in the process for the manufacture of the arsenates of the alkaline-earth metals
IPC: C01G28/02
Filed: 1924-11-18
Abstract: The production of alkaline earth arsenates by heating the arsenites in presence of oxygen as described in the parent case, is effected at temperatures above 450 DEG C., for instance 600-700 DEG  C. or even a cherry-red heat.  The air may be heated to the necessary temperature before being passed over the arsenite, or combustion gases containing excess of oxygen may be brought into contact with the arsenite.  In an example the hot gases from a furnace containing excess of oxygen or with the addition of air are passed through a rotary kiln containing the arsenite.  The Specification as open to inspection under Sect. 91 (3) (a) mentions the use of a rotary kiln heated by a pulverized coal burner.

In a method of splicing wires to leads extending from opposite sides of electrical components, the components are fed into position with each lead resting in a U- shaped electrical connector, a wire is laid in each connector parallel with the lead and the connector simultaneously crimped about the wires and leads. A machine for carrying out this operation comprises a reciprocating ram 14 which drives a pair of feed fingers 18 and to which are mounted pairs of dies 20, depressors 22, a plate 24 carrying a manual feed mechanism 26, a mechanism 28 and a feed mechanism 30 for a connector strip 10. The mechanism 26 comprises a block 34 carrying a spring-loaded slide 36 retained by a bolt 40 and a stirrup 42 and to which is secured a finger-piece 46. The mechanism 28 comprises a well 48 in which is mounted a spring-loaded double-ended anvil 50 and a pair of shear members 52 retained and limited in operation by keys 56. The mechanism 30 comprises a plate 68, a spacer bar 70 and spring-loaded holddown plates 72 having slots through which the pins 76 of the fingers 18 engage the holes 12 of the connector strip 10. In operation, with a pair of connector strips 10 in position the finger-piece 46 is moved forward to feed the leads 4 of a pre-positioned component 6 into the U-shaped connector 8, pieces of wire 2 are positioned in the notches 58 of the members 52 so that the ends engage the connector, and the press operated. As the ram descends the dies 20 crimp the connectors about the leads and wires and the depressor 22 operates the shear member 52 to shear the connector 8 and the strip along the lines A-A, B-B. As the ram 14 ascends the pins 76 engage the holes 12 of the strips 10 to feed them between the plates 68, 72 whilst the assembled component is stripped from the dies 20. In a modification the components 6 may be fed from a magazine 78 mounted above the plate 68.

Title: Improvements in and relating to insulated metal wire and coating compositions for use in the production thereof
IPC: C09D5/25
Filed: 1951-11-30
Abstract: Insulating coatings on wire are formed by passing the wire through a solution of a mixture of more than 50 per cent. of an epoxide resin having more than one epoxy group per molecule with a mixed curing agent consisting of an alkylated amino-formaldehyde resin and a polybasic acid, and with an alkyd resin as plasticizer, and baking the varnish.  The proportion of plasticizer is adjusted in accordance with that of curing agent to give the required flexibility and hardness to the film.  The term alkyd resin is defined as including alkyds modified by monobasic acids or monohydric alcohols.  The flexibility required in the films is defined by tests applicable to different gauges of wire being coated.  The preferred epoxide resin is a condensation product of epichlorhydrin and 4,41- dioxy-diphenyl-dimethylmethane.  Such resins are marketed under the R.T.M. "Epikote."  The preferred amino resin is a butylated urea or melamine-formaldehyde resin.  Suitable p  compositions contain the following ingredients.  (1) "Epikote" resin, citric acid, butyl alcohol solution of butylated melamine-formaldehyde resin, butyl alcoholxylol solution of butylated urea-formaldehyde resin, castor oil modified glyptal resin, diacetone alcohol, solvent naphtha and butyl alcohol.
