Abstract: 756,505. Cutting plaster bandages. AKTIEBOLAGET DENTATUS. June 17,1954 [June 30, 1953], No. 17796/54. Class 81(2). [Also in Groups VIII and XXIII]- A surgical hand tool is provided with a hydraulic pressure operated working member carrying a working tool for reciprocatory movement and is connected by a .pressure conduit with a pressure impulse generator so that pressure pulses are transmitted to the working member. A plaster or bandage cutter 10 is secured to a piston rod 9 and piston 7 which are reciprocated within a cylinder 3 and a casing 1 by impulses transmitted by a pressure fluid e.g. oil, in a conduit 4 which is connected with a space in the cylinder 3 above the piston 7. On a downward movement of the piston 7 against a spring 11, the cylinder 3 moves upwardly to an adjustable limiting screw 22. An upper holding-on tool 17 secured to the cylinder 3 is provided. A lower holding- on tool 18, which is provided with a part 19 projecting beneath the cutter 10 and upwardly projecting shoulders for stressing the material to be cut, is secured to the casing 1.

Abstract: 828,801. Resilient mountings; assembling rubber-bush mountings. GENERAL TIRE & RUBBER CO. June 8, 1956 [June 14, 1955], No. 17814/56. Class 108(3) The invention relates to a resilient mounting comprising a rubber insert 3a radially compressed between a rigid outer sleeve 1a and an inner rigid sleeve or core 2a, and having when unstressed, before assembly, a radial thickness greater than the radial distance between the sleeves 1a and 2a, and being inserted between the latter with the aid of a temporary lubricant absorbable by the insert 3a. According to the invention, a single internal axially-concave circumferential recess 7a is provided in the sleeve 1a to hold the insert 3a in place until the lubricant is absorbed thereby, the radial depth of the recess 7a being approximately 10 to 20% of the radial thickness of the sleeve 1a and its axial width being several times this radial thickness. As shown, the sleeve 1a is formed with two bores 6a, 18, of different respective diameters, and a flange 4a. The ends 19, 20 of the sleeve 2a are serrated. In its unstressed condition before assembly, the insert 3a is annular in shape except for a flared mouth to its bore at the flange end, and a tapered outer circumference at the other end. The recess 7a may alternatively be of the shape shown in Fig. 7 at 7b. Another construction is described (Figs. 1 to 4, not shown) in which the insert is formed with a flange in its uncompressed state and the inner sleeve 2a and the insert 3a extend beyond the end of the sleeve 1a at the end of the mounting opposite to the flange 4a. The sleeve 1a may be formed by a punching operation the recess 7a being produced by drawing.

Abstract: 1275345 Salts of α-carboxybenzylpenicillin PFIZER Inc 14 April 1970 [30 Dec 1969] 17817/70 Heading C2A Crystalline mono-sodium or mono-potassium α-carboxybenzylpenicillinate is prepared by extracting an aqueous solution containing 5-40% by weight of α-carboxybenzylpenicillin with nbutanol, n-amyl alcohol, isoamyl alcohol, methyl ethyl ketone, or methyl isobutyl ketone at pH 2-3À5, separating the organic layer and adding thereto at least an equivalent amount of sodium or potassium lactate as aqueous solution of 70-90% of the lactate, and recovering the resulting precipitate of mono-sodium or monopotassium α-carboxybenzylpenicillin. The starting aqueous solution may be of α-carboxybenzylpenicillin itself, a salt thereof such as mono- or di-alkali or alkaline earth metal, amine, ammonium or substituted ammonium salts, or an impure reaction solution containing the penicillin, such as solutions resulting from procedures used to prepare α-carboxybenzylpenicillin (e.g. alkaline hydrolysis of α-carboxybenzylpenicillin phenyl ester). Adjustment of the pH to 2-3À5 may be effected before or after mixing the aqueous solution and extracting solvent, e.g. using HC1, HBr or H 2 SO 4 . The organic solvent extract is preferably at least partially dried after separation, e.g. with a drying -agent or by azeotropic distillation in vacuo. Alternatively the ratio of organic solvent : water contained therein may be reduced by addition of dry further solvent. The precipitated required salt may be washed with an organic solvent and dried. The inventive mono-sodium or -potassium salts may be converted to the corresponding dialkali metal salt by suspending in water, adding the stoichiometric amount of sodium or potassium hydroxide isopropoxide, butoxide, bicarbonate or carbonate, and isolating the resulting di-salt, e.g. by spray-drying, lyophilization or addition of a water-miscible non-solvent. The mono-sodium salts may be solubilized, e.g. for use as injectable preparations, by intimately mixing with a stoichiometric amount of sodium glycinate. Pharmaceutical compositions for reconstitution with water to provide an injectable form comprise a dry sterile mixture of the inventive crystalline mono-sodium α-carboxybenzylpenicillinate and a stoichiometric amount of sodium glycinate to form the disodium salt.
