IPC: H01G4/35
Filed: 1949-01-14
Abstract: 671,347. Condensers; mounting terminals. BRITISH THOMSON-HOUSTON CO., Ltd., and DYER, G. H. Jan. 11, 1950 [Jan. 14, 1949], No. 1112/49. Classes 37 and 38 (i). A condenser comprises a single, solid, rigid conductor extending through both ends of a metal casing 1 which houses a condenser unit 6, the leads of which being connected one to the casing 1 'and one to the conductor 2, and each end of the casing 1 is sealed by a bushing 3 or 13, e.g. of rubber, glass, or ceramic, engaged intermediate its length by a metal cover 10 or 12 secured to the casing 1. The condenser unit 6, which is of the rolled type, is insulated by cylinders 8, 9 from the conductor 2 and casing 1 respectively. The bushings 3, 13 are carried between flanges 5, 4 and 14, 15 respectively on the conductor 2. A spacer 11, e.g. a cup-shaped washer, separates the cover 12 from a cupshaped plate 10 which serves as an electrical connection between the unit 6 and .casing 1. At the other end a washer 7 serves the same purpose between the unit 6 and conductor 2. If the bushings 3, 13 are of glass or ceramic, metal members may be soldered thereto, these being then soldered to the cover and conductor. Alternatively the bushing may be soldered directly to the cover and conductor, 671,356. Electro-deposition of gallium. FRARY, F. C. March 31, 1948 [April 5, 1947]; No. 9079/48.

Title: Improvements in or relating to valves for reducing gaseous pressure
Inventor: YOUNG DAVID HERBERT
IPC: G05D16/06
Filed: 1956-01-12
Abstract: 833,221. Fluid-actuated valves. KIDDE CO. Ltd., W. Jan. 3, 1957 [Jan. 12, 1956], No. 1134/56. Class 135. A pressure-reducing valve for connection, e.g. to a gas cylinder, comprises a valve body 2 having inlet and outlet connections 1, 38 and a chamber 35 housing a diaphragm 18 clamped between the valve body and a cap nut 22. The diaphragm is loaded by a spring 20 in opposition to outlet pressure and carries an internallythreaded bush 23 which co-operates with an adjustable plunger 24. Adjustment of the plunger is accomplished by rotation of a cover 27 secured by screws to a cap member 26 having a splined connection with the plunger head. Balls 28 prevent axial movement of the cap member and its cover relative to the valve body and the engagement of a spring-loaded ball 29 in a series of recesses 30 in the cap member permits the adjustment of the plunger to various positions to rapidly adjust the valve outlet pressure. The plunger 24 abuts a valve support member 9 to hold a valve member 3 off its seat 5. The valve member being screwed into the support member and locked in position by a lock-pin 10. The support member is hexagonally shaped with rounded corners to permit sliding movement in a tubular guide 7 and the passage of gas through the guide. The outlet from the chamber 35 is provided with a filter 36 and a throttling screw 41. A relief valve 31 similar in construction to a conventional tyre inflating valve relieves pressure to the atmosphere when its stem abuts an adjustable screw 32 consequent upon the diaphragm being subjected to excessive pressure. In a modified construction the spring-loaded diaphragm 18 may be replaced by a spring-loaded piston provided with splines or other means to prevent its rotation. According to the Provisional Specification a spring-loaded bellows may be used instead of the diaphragm.

Title: Improvements in the manufacture of polymeric nitrogenous derivatives
IPC: C08G69/28
Filed: 1940-01-19
Abstract: 538,120. Polymeric nitrogenous derivatives. HARRISON, W. Jan. 19, 1940, No. 1175. [Class 2 (iii)] High molecular weight long-chain nitrogenous compounds are prepared by bringing together a diamine or a polyamine, or an oxygen-linked chain diamine or a sulphur-linked chain diamine, and a carbothiolic acid, and heating the ingredients or the reaction products of the ingredients to a temperature below 180‹C., with or without subsequent heating to carry further the polymerization of the compound. The carbothiolic acid itself may have an oxygen-linked or sulphur-linked chain. Alternatively, the'starting materials may be amine derivatives containing, at one end of the molecule, a terminal - SH group, and at the other end a -NH 2  or - NH group, the terminal groups being separated by at least one carbon atom. When the basic constituents are in sufficient excess to prevent the retention of terminal -COSH groups, and the reactions are carried out in the absence of air or oxidizing agents, the compounds formed are usually identical with those formed when dibasic carboxylic acids are used instead of carbothiolic acids. When the acid constituents are in excess, there remain terminal -COSH groups which may be reacted with oxidizing agents, aldehydes &c., to modify the products. According to examples : (1) the salt prepared from hexamethylene diamine and di-thio-adipic acid is dissolved in mixed xylenols and heated for 2 hours at 130‹C. in an atmosphere of nitrogen. The temperature is then raised to 150‹C. and heating continued for another 2-4 hours ; (2)the salt from decamethylene diamine and thioldiglycollic acid is heated in meta-cresol for 4-6 hours at from 130-150‹C., and the solvent then removed by distillation in vacuo; (3) the salt from pentamethylene diamine and dithio-thiolglycollic acid is treated as in Example 2 ; (4) diamino diethyl ether is substituted for decamethylene diamine in Example 2 ; (5) diamino triethyl ether is substituted for pentamethylene diamine in Example 3 ; (6) the salt from diethylen triamine and dithio-azelaic acid is heated in mixed xylenols for 2 hours at 160‹C. in an atmosphere of nitrogen. The temperature is then raised to 140-150‹C. and heating con tinued for a further 2-3 hours. A water-soluble viscous product results. Further heating at 160-200‹C. gives an insoluble resin ; (7) the salt from hexamethylene diamine and imino thiolglycollic acid is treated as in Example 6 ; (8) 6-amino-thio-caproic acid is heated in phenol for 4-6 hours at 130-160‹C. in an atmosphere of nitrogen.

Filed: 1954-01-20
Abstract: 761,385. Damp proof courses. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 19, 1955 [Jan. 20, 1954; Feb. 1, 1955], Nos. 1751/54 and 2988/55. Class 20(4)  In a method of forming a damp course in situ in a porous wall structure a waterproofing material in a liquid state is brought into contact with one or both faces of the wall and allowed to percolate into and through the wall. The waterproofing material may be a dilute solution of a wax, e.g. paraffin wax (m.p. 49‹C.), a metal soap, e.g. calcium and aluminium stearates and oleates, or a silicone, e.g. tertiary alkoxy-chloro- (or amino-) silanes and methyl chloro- or methylaminosilanes. Suitable solvents for the waterproofing materials are white spirit, toluene or xylene, or mixtures thereof or carbon tetrachloride. Alternatively a wax, grease or metal soap which is solid at normal temperatures and will not migrate at such temperatures through a porous material may be used and be maintained in a liquid state to penetrate the wall by local heating of the wall and the material, e.g. by steam, electric, infra red or high frequency heaters. In applying the water-proofing material holes may be drilled into or through the wall from one or both faces thereof. Holes not extending through the wall are downwardly inclined from the entry end. The water-proofing material may be applied by feeding it at constant level or under pressure to hollow spikes having perforated walls which are inserted in the holes. In modifications the water proofing material is contained in a gutter or a trough as shown in Fig. 1. or it may be held in a porous pad maintained against the wall as shown in Fig. 4. The wall is preferably treated in a dry state. Walls which are not dry may be pretreated with a 1-3 per cent solution of a water displacing fluid, for example cetyl pyridium bromide, cocoamine-technical or the di-amine or cocamine acetate technical dissolved in carbon tetrachloride or in white spirit, xylene, toluene or mixtures thereof. Alternatively water displacing fluids may be incorporated in the waterproofing composition. In an example a waterproofing composition containing water displacing fluid consisted of silicone 5 parts by weight; cocodiamine technical 2 parts by weight; white spirit 65 parts by weight; toluene 18 parts by weight; butyl alcohol 10 parts by weight. A wall may require more than one treatment to provide an effective damp course.

Abstract: 737,934. Internal shoe-drum brakes. BRISSON, L. C. Jan. 23, 1953 [Jan. 26, 1952], No. 2087/53. Class 103 (1). In an internal shoe-drum brake, a brake application is initiated by applying an auxiliary or starting shoe 2 to the drum, preferably by supply of fluid pressure to an actuator cylinder 5, the force of the drum on the shoe 2 causing rotation of a member 6 which through the reduction gearing 8, 9 causes rotation of an eccentric cam 12 to apply a primary main shoe 4 which itself acts through a linkage 16, 19, 21 upon a secondary main shoe 3, one end of which bears against a fixed abutment surface. As shown the pivotal rotation of the main shoes 3 and 4 is opposite to that of the auxiliary shoe 2 and non-self-energizing with respect to a drum rotation as shown by the arrow, but a more powerful brake could be provided by arranging for the main shoes to pivot at the other ends. A further eccentric cam, not shown, would be provided to give operation for a reversed rotation of the drum. In another embodiment the link 19 connecting the primary and secondary main shoes is disposed above instead of below the brake axis. The brake is similar in certain respects to that described in Specification 737,935.
