Title: Process for the making of adrenocorticotrophin preparations having a prolonged action
Filed: 1952-03-25
Abstract: Adrenocorticotrophin (ACTH) preparations for implantation or injection intramuscularly or subcutaneously to give a prolonged action, are prepared by adding an alkaline protein, or protein degradation product, and a water-soluble zinc salt to an adrenocorticotrophin solution in water, and adjusting the pH of the solution to pH 6-8 by the addition of a buffer salt or a buffer salt mixture.  Protamine sulphate is the preferred alkaline protein, and zinc sulphate the preferred zinc salt.  A preservative such as tricresol is incorporated after the adjustment of pH.  The preferred buffer is trisodium phosphate. In the example, ACTH is dissolved in 1 per cent aqueous protamine sulphate solution, a solution of zinc sulphate and glucose in water is added, and the pH adjusted to pH 7.0-7.2 by the addition of trisodium phosphate in water.  Tricresol is then added.  If desired the adrenocorticotrophin preparation may be separated from the aqueous suspension by filtration or centrifugation, and resuspended in other media e.g. waxes (tablets for implantation) and vegetable oils (injections).

Title: Improvements in and relating to insulating and dielectric compositions
IPC: H01B19/02
Filed: 1938-03-15
Abstract: 506,560. Electric insulation; electric condensers. BRITISH THOMSON-HOUSTON CO., Ltd. March 15, 1938, No. 8032. Convention date, March 18, 1937. [Classes 36 and 37] [Also in Groups III, IV, and VIII] An electric insulation comprises a porous cellulosic material impregnated with a dielectric substance consisting wholly or partly of a chlorinated diphenylene oxide that is solid at normal temperatures. In particular a fibrous cellulosic material impregnated with a mixture of chlorinated diphenylene oxide and pentachlordiphenyl, the mixture being solid at normal temperatures. Direct chlorination of diphenylene oxide, e.g. at 125-180‹ C., in the presence of a catalyst such as iron, antimony or iron' chloride or antimony chloride produces solid products of wax-like consistency having high dielectric constants. After chlorination, the products are washed with dilute aqueous alkali and fractionally distilled preferably under reduced pressure. Mixtures of isomers are generally employed, and a table is given of their properties. Suitable capacitors consist of aluminium foil with interposed sheets of Kraft paper impregnated with the dielectric Such capacitors have high capacity, low power factor, and the variation of capacity with temperature is small. Monochlordiphenylene oxide is specifically mentioned as suitable for capacitors and for wrappings of cable joints. The tetrachlor compound is mentioned in connection with capacitors and transformer insulation wrappings. A capacitor is mentioned with Kraft paper impregnated with the isomeric mixture of the trichlordiphenylene oxide as dielectric. The tetra- and pentachlor derivatives are preferred when non-inflammability is important. Chlorinated diphenylene oxide may be used in admixture with mineral oil, waxes, tars, asphalts, pitches and other dielectric liquids or solids, e.g. pentachlor diphenyl or pentachlordiphenyl oxide or trichlorbenzene or chlorinated diphenyl and trichlorbenzene. Condensers employing chlorinated diphenyl or chlorinated diphenyl oxide as dielectrics decrease in capacity as temperature increases from 25-76‹ C. The capacity of capacitors using chlorinated diphenylene oxide on the other hand increases, so that by suitably blending, a dielectric can be obtained of substantially constant capacity over the temperature range 25-76‹ C. The Specification as open to inspection under Sect. 91 is not limited to the use of cellulosic material impregnated with a halogenated diphenylene oxide but includes insulating compositions generally comprising halogenated diphenylene oxides. It is stated that these compounds may be prepared with fluorine, bromine or iodine in place of chlorine. This subject-matter does not appear in the Specification as accepted.
