Abstract: 506,427. Hydrocarbon polymers. STANDARD OIL DEVELOPMENT CO. Oct. 26, 1937, No. 29219. Convention date, Dec. 11, 1936. [Class 2 (iii)] Vulcanized rubber-like products are prepared by treating an isobutylene-polymer having a molecular weight below 40,000 with sulphur monochloride or dichloride in an amount of from 1 to 100 per cent of the polymer treated, at a temperature of between 80 and 200 C. for a. time between 10 minutes and 50 hours. Fillers and reinforcing agents such as carbon black, litharge, and zinc oxide, and rubber vulcanization accelerators such. as organic amines, e.g. hexamethylene tetramine, or di- or triphenyl guanidine, may be mixed with the polymer before treatment. The treatment may be carried out in the presence of a solvent or diluent such as naphtha; carbon tetrachloride or carbon disulphide. The product may be precipitated from the solvent by alcohol or acetone and may be purified by dissolving in benzene, adding a diatomaceous earth and filtering through powdered sodium hydroxide. The products may be used for the preparation of rubber goods, e.g. tyres, and in the preparation of high-pressure lubricants. In examples, polyisobutylene, either alone or dissolved in 1 : 1 : 2 : 2-tetrachloroethylene or o-dichlorobenzene, is treated with sulphur monochloride. According to the Specification as open to inspection under Sect. 91, the process is applied to a plastic or elastic substantially saturated linear type hydrocarbon material having a molecular weight below 40,000. This subjectmatter does not appear in the Specification as accepted.

Title: A method of hardening cast iron
Filed: 1929-09-27
Abstract: Cast iron is locally hardened, e.g. in the formation of a turning or other machine tool, by bringing copper or other suitable non-ferrous metal e.g. copper alloys close to the cast iron and generating intense heat by passing an electric current between them causing a penetration of the copper &c. into the cast iron.  A continuous arc may be struck between a copper electrode and the cast-iron bar or intermittent contact as in flash welding may be employed the castiron electrode being preferably sheathed with copper or a cast-iron bar may be mounted in a practically enclosed crucible between one or more pairs of non-ferrous metal contacts and a heavy electric current passed until the metals are melted at the points of contact.

Title: Improvements relating to liquid measuring and dispensing apparatus
Inventor: SMALE NORMAN EDWIN
IPC: B67D7/16
Filed: 1950-11-30
Abstract: 711,274. Dispensing liquids. WAYNE TANK & PUMP CO., Ltd.. and SMALE, N. E. Nov. 29, 1951 [Nov. 30, 1950], No. 29315/50. Class 116 [Also in Group XIX] In a liquid fuel measuring and dispensing apparatus comprising an electricmotor-driven pump which forces the fuel through an air separator, a meter associated with indicating mechanism, and a flexible hose to a dispensing nozzle, after the motor has been switched off at the end of a dispensing operation, a connecting member is rendered incapable of transmitting an operative effort from a switch control means to a switch operating means until zeroizing has been performed, so that manipulation of the switch control means in an attempt to switch on the motor prior to zeroizing is ineffective. The invention is described in connection with an electricmotor-driven petrol pump comprising mechanism (not shown), including numeral drums, for indicating the quantity of petrol dispensed, and a zeroizing shaft 22 therefor which is adapted to be rotated through 405 degrees and spring-returned through 45 degrees. If the motor-switchcontrol arm 10 is moved up from the " off " position shown, a shaft 11 and T-member 13 will be rotated clockwise thus causing a peg 182 on a trip member 18 to ride into recess 132 and rotating the lever 14 on which the trip member is pivoted at 17. This lever is freely mounted on a bearing bush for shaft 11, and has at one end a swivel which is slidable between adjustable lock-nuts 145 on a switch-actuating rod 15, and at the other end a locking face 144 which co-acts with a recess 212 on a member fixed to the shaft 22 to prevent zeroizing while the motor is switched on. When the arm 10 is returned, to switch off the motor, the peg 182 will be released so that the member 18 will be rotated away from the member 13 by spring 19, and, after lost motion, a cranked portion 134 will engage the lever 14 to cause it to rotate to the "off" position with the member 13. The motor cannot now be switched on again until zeroizing is effected and a projection 211 co-acts with arm 184 to return the trip member 18 to the operative position shown during the return movement of shaft 22. According to the Provisional Specification, the functions of the T-member are performed by a cam.

Title: Process for dyeing and printing textile materials
IPC: D06P1/00
Filed: 1960-08-25
Abstract: In the dyeing or printing of textile materials with vat dyestuffs, the materials are impregnated or printed with a vat dyestuff in which a reactive hydrogen atom, e.g., the hydrogen atom of a hydroxyl or -NH- group, has been replaced by an organic acyl residue containing at least one water-solubilising group, e.g. a quaternary ammonium or sulphonic acid group, and at any stage of the dyeing or printing operation, prior to the final oxidation step, the dyestuff is treated with an alkali and a reducing agent, to form the leuco compound and split-off the acyl residue, whereupon the so-formed leuco compound is fixed on the fibre and finally oxidised.  The aqueous dyebath, padding liquor or printing paste may contain the dyestuff, the alkali, e.g. sodium hydroxide, and the reducing agent, e.g. sodium hydrosulphite or thiourea dioxide, or alternatively, the materials may first be padded with an aqueous solution of the dyestuff, then, if desired, dried, and subsequently treated with an aqueous solution of the alkali and the reducing agent.  The vat dyestuff may be of the anthraquinone, perylene, pyrenequinone or indigoid series and the acyl residue may be that of an aliphatic, heterocyclic or aromatic carboxylic or sulphonic acid.  Examples are given.  The acyl residue may be introduced into the vat dyestuff by reaction with a sulphocarboxylic acid halide, especially a sulphobenzoic acid chloride, in the presence of a tertiary base such as pyridine, or with the reaction product of sulphur trioxide and benzoyl chloride. Typical dyestuffs are those of the formulae <FORM:0891214/IV (c)/1>

Abstract: 696,383. Electrolysis; batteries. BABCOCK & WILCOX CO. Dec. 8, 1950 [Dec. 28, 1949], No. 30123/50. Classes 41 and 53. A method of circulating electrolyte in a cell includes establishing a vertically-extending laterally-confined zone of electrolyte, the zone extending to the surface of the electrolyte and communicating at its lower end with the lower strata of electrolyte, and applying a gas through a lateral opening to the electrolyte in the upper portion of the zone at a pressure only just sufficiently greater than the electrolyte head at the point of introduction, to ensure a flow of gas to aerate the confined electrolyte and decrease its average density, whereby circulation is effected from the lower strata of electrolyte through the confined zone to the surface of the body of electrolyte. In the storage battery cell shown, which contains electrodes 12, 13 spaced apart by separators 14, a vertical tube 20 at one end of the cell extends from a point near the bottom of the cell to a point above the upper surface of the electrolyte 15. A lateral orifice 21 in the tube is connected to an air blower 30 which may comprise the source of ventilating air for the battery room. Air flowing into the tube causes a circulation of the electrolyte from the main body into the tube at the bottom, the electrolyte overflowing at the top of the tube. In a modification the tube is replaced by a compartment formed by a vertical bore formed in an end wall of the cell, lateral openings being formed at the top and bottom for communication with the main body of electrolyte. The air-blower communicates with the bore through an opening in the end wall.

Abstract: <PICT:0713414/III/1> <PICT:0713414/III/2> In a gas washing process (see Group XII) wherein sulphuretted hydrogen and other impurities are extracted from the gas by methanol in three stages at a pressure of 22 atmospheres and a temperature of -30 DEG  C., the methanol containing H2S, CO2 and inert gases (H2, CO, CH4 and N2) in solution obtained in the second stage is passed from the washer 4 into a vessel 5 wherein the pressure is reduced to 5 atmospheres, about one third of the CO2 content and all the inert gases but only a minor proportion of the H2S being freed at this pressure, to be withdrawn through a pipe 15.  The solvent is then passed into a degasifier 6 wherein the pressure is reduced to atmospheric and then to vacuum, the H2S and CO2 evolved in volume proportions of about one to ten being withdrawn though a vapour trap 18.  The H2S concentration in the degasifier gas may be raised to 95 per cent. by passing the solvent from the washer 4 into a vessel 45 (Fig. 2), at 3 atmospheres pressure, the CO2 and inert gases being purged from the liquid by a countercurrent stream of gas rich in H2S pumped from vessel 46 and column 47 by a compressor 49, the solvent passing from 45 into vessel 46 which is at a pressure of 1.2 atmospheres and from which 95 per cent. pure H2S is withdrawn.  The remaining H2S in the solvent is purged therefrom in column 47 by a stream of nitrogen.

A level controller, e. g. for the collector tank 10 of an aircraft fuel system, comprises a floatoperated double beat pilot valve 15 controlling leak-off from a chamber 29 supplied from the inlet 21 via a guide tube 27 for the main valve closure member 19, a slot 34 in the said tube and ports 32 in an extension 26 of member 19. The main valve closure member is carried by a diaphragm 24 and urged to engage its seat 20 by a spring 30. When the float 13 closes the pilot valve, pressure within chamber 29 builds up to inlet pressure and closes the main valve. When the level falls, the pilot valve opens to decrease the pressure in chamber 29 and thereby allow the pressure in the inlet to open the main valve. As the main valve opens, it increases the available flow area of slot 34 and thereby provides a positional feedback. The shape of slot 34 is such as to provide proportionality between the extent of opening of the pilot valve and that of the main valve. A relief valve 31 obviates damage due to pressure surges in the inlet.
