Patent GB-625146-A (GB)
Title: Improvements in or relating to a process for the separation of histamine from streptomycin
Filed: 1946-12-12
Abstract: Histamine is removed from streptomycin by adsorbing said substances from their aqueous solutions on to an inorganic base exchange material and removing the streptomycin by selective elution with a dilute aqueous solution of a material capable of displacing the streptomycin therefrom by base exchange such as alkali metal and ammonium salts or hydroxides.  Preferred base exchange materials are the natural or synthetic alkali metal or alkaline earth metal alumino-silicates especially sodium alumino-silicates.  Preferred eluants are aqueous solutions of sodium chloride of a concentration of 1-8 per cent, preferably 3-5 per cent.  When solutions of a concentration of more than 4 per cent are used for regenerating the base exchange material the resulting solution remains contaminated with histamine which may be removed by treatment with fresh base exchange material. Histidine present in the original streptomycin solution may be removed from the base exchange material by treatment with very dilute sodium chloride solution, e.g. 0.5 to 1.0 per cent or a 0.5 to 2 per cent pyridine solution.  The histamine may be recovered by its salt with 2 : 4-dinitro-1-naphthol-7-sulphonic acid. In examples: (1) streptomycin is purified by adsorption on a synthetic sodium alumino-silicate and elution with 1 per cent sodium chloride; (2) streptomycin is freed from histidine and histamine by adsorption on synthetic sodium aluminosilicate, washing with 1 per cent aqueous pyridine, elution with 5 per cent sodium chloride and passing the resultant solution through a fresh bed of ion-exchange material to remove the remaining histamine. Specification 616,955 is referred to.

[Class 138 (ii)] The shoe 8 of an ironing-machine is mounted on a rod 11 which is carried by a member'21 pivoted to the housing 3 and releasably latched thereto through an intermediate member 39 which is pivoted to the member 21 and is forced - by a spring 32 against a web 34 of the housing 3, the spring determining the pressure exerted between the roller and shoe. The parts 21 and 39 are locked together by a slidable and rotatable rod 37 which engages an aperture 40 in 'the member 21. Rotation of the shaft 37 acting through a cam causes the shaft to slide and be withdrawn from the aperture 40 whilst another cam on the shaft positively engages a part of the member 21 and positively moves it so that the shoe moves out of engagement with the roller. The shoe is mounted on the rod 11 through a sleeve 10 which is provided with cam surfaces 12, 12a engaging a pin 13 projecting from the rod whereby the shoe may pivot relatively to the rod. The roller 51 is moved into and out of contact with the shoe by each half-rotation of the eccentric 57 on which the roller is mounted. The shaft 70 on which the eccentric is secured is clutched to the constantly running worm-wheel 90 by a clutch operated by a knee pad under the control of 'the operator, the clutch being automatically thrown out after a half revolution.

Title: Basic perinone dyestuffs and processes for their manufacture
IPC: C09B57/12
Filed: 1966-08-23
Abstract: The invention comprises basic perinone dyes of the general formula <FORM:1112734/C4-C5/1> wherein A and B are aryl residues, e.g. benzene or naphthalene condensed with the heterocyclic ring system in the ortho or peri positions, "alk" is an alkylene group, preferably having one or two carbon atoms, R1, R2 and R3 are each alkyl or aralkyl residues or together with the N atom may form a heterocyclic ring, e.g. pyridinium, and X is an anion.  They are prepared by reacting an appropriate halogeno-acylperinone having a group =B-CO-alk-halogen with an excess of a tertiary amine N(R1)(R2)R3 (or pyridine), or with a theoretical amount of amine in presence of an inert solvent e.g. dimethylformamide.  The anion X may be derived from halo-acids, sulphuric, phosphoric, formic, acetic, chloro-acetic, oxalic, lactic or tartaric acids and double salts with zinc or cadmium chlorides may be obtained.  The dyes give orange-red shades on tannined cellulose, silk, hair, leather, polyacrylonitrile or polyvinylidene cyanide.ALSO:Phthaloperinone is worked into a sludge with carbon disulphide and then reacted with chloracetyl chloride and aluminium chloride at room temperature for 10-15 hours with stirring. The carbon disulphide is decanted and the residue decomposed by adding ice. The chloracetyl compound which separates is filtered and dried.

Title: Skid control system
IPC: B60T8/50
Filed: 1975-09-16
Abstract: 1527902 Antiskid braking systems EATON CORP 16 Sept 1975 [26 Sept 1974] 38082/75 Addition to 1389845 Heading F2F  A pressure modulating valve assembly 30 allows a rapid exhaust of brake pressure from a brake cylinder 14 when a sensor 40 detects an incipient skid followed by a rapid rise to a lower pressure than at first (see K in Fig. 6) followed by a further increase at a reduced rate on subsequent brake application. To this end the assembly 30 includes a relay valve 70 with a first piston portion 78 responsive to control pressure in an inlet chamber 44 and the opposed brake or outlet pressure in a chamber 46, a second piston portion 89, preferably of the same effective diameter as the first portion 78, responsive to a bias pressure in a chamber 52, and an opposed compensating pressure in a chamber 50 which communicates with the outlet or brake pressure through passages 98 and 99 and a valve 100 with a bleed hole 104 in parallel to a dump valve 108. This opens at a predetermined pressure differential to limit the differential between the chambers 46 and 50. In the absence of skidding the piston part 78 acts as a normal self-lapping relay valve, biased by a spring 90, in response to a control pressure from a drivers valve 24 communicated through an open modulating valve 62. Control pressure air passes through an orifice 97 and passage 96 to raise the bias chamber pressure to the control pressure. The spring 92 maintains the second piston portion 89 against a stop 94. In the skid mode the solenoid valve 62 closes the passage 58, which, while allowing the bias chamber pressure to increase, exhausts the chamber 44 through passage 60 and an exhaust port 68 allowing the piston portion 78 to rise and exhaust the brake cylinder through exhaust passage 122.  On reapplication of the brakes the bias chamber pressure acting below the piston portion 89 is effective to close the inlet valve at successively lower pressures than before, the subsequent low rate of pressure rise (from the knee K of Fig. 6) occurring as the compensating chamber pressure differential bleeds through the valve 100 to the chamber 46.

Abstract: A water-soluble sizing material in sheet form is made by converting fibrous cellulosic material in sheet form and of appropriate thickness into sodium carboxymethyl cellulose while maintaining the original fibrous structure of the cellulosic material, so that the sodium carboxymethyl cellulose fibres thus made are separated by many capillary air spaces which prevent the fibres from sticking to each other.  The cellulosic material, which may be wood pulp, may be treated first with aqueous caustic soda and then with aqueous sodium chloroacetate, or vice versa, the product being thereafter purified, or neutralised and purified, care being taken throughout not to deform the original structure of the cellulosic material. Preferably, the aqueous reagents contain as little water as possible, and a hydrophilic organic solvent, e.g. methanol, ethanol or sec- or tert-butanol, may be added to each.  The product may be purified by washing with an aqeuous solution of one of these solvents, and may be neutralised, before or after purification, with an acid, preferably an organic acid, e.g. acetic acid, in hydrophilic alcoholic solution. A water-soluble fluorescent bleaching agent, e.g. "Blankophor B" (Registered Trade Mark), and a water-soluble colourless and odourless germicide, e.g. hexachlorophene, may be absorbed on the fibres of the product.
