摘要： 451,119. Pipe joints. SWINDIN, N., and NORDAC, Ltd., Rosslyn Crescent, Wealdstone, Harrow, Middlesex. Feb. 8, 1935, No. 4174. [Class 99 (i)] In a joint of the kind in which a pipe of rubber or containing rubber has its flared end clamped on to a tapered union-plug by a sleeve and coupling nut, the plug, sleeve and nut are formed from or coated with a corrosion-resistant material comprising rubber, preferably the material known under the Registered Trade Mark " Vulcoferran." Two pipes are connected by a double conical plug 29, sleeves 34, 35 and a nut 36 screwing on to sleeve 34. The coned plug is formed as shown to connect pipes of different sizes. In joining a pipe to a valveplate 40, Fig. 3, a metal nipple 42 having a tapered extension 44 is screwed into the valve plate, the nipple and rear side of the plate having a covering 45 of corrosion-resistant material.

摘要： 353,520. Flexible pipe couplings. SWINDIN, N. and NORDAC, Ltd., Reno Works, Rosslyn Crescent, Wealdstone, Middlesex. April 25, 1930, No. 12856. [Classes 99 (i) and 99 (ii).] A flexible pipe coupling has one or more circumferential folds 17 so that it can be compressed longitudinally for connection to the nipples 11, 21, and the ends of the coupling are formed internally or externally with screw threads preferably of opposite hand so that rotation of the coupling suffices to screw it into position. The coupling may be made wholly or in part of a rubber composition such as that known under the registered Trade Mark "Nordac," containing not more than 55 per cent of rubber. The ends of the coupling may be of hard rubber or vulcanite moulded integrally with the softer intermediate portion.

摘要： 339,002. Swindin, N., and Nordac, Ltd. Sept. 5, 1929. Emulsions, making.-An aqueous liquid is dispersed in unvulcanized rubber by kneading after the rubber has been softened by heating or the use of a solvent, if desired with the addition of a hard, porous, inert powder such as coke dust, which acts as a triturating agent. An emulsifying agent such as soap, saponin, borax, ammonia or soda may be added if other substances are to be milled into the rubber. The paste is mixed with a water-setting cement to form acid-resisting linings, floor coverings &c. The retarding effect on the setting of the cement of the solvent when used in minimized by the addition of high melting resins or bitumens such as cumar or gilsonite.

摘要： 660,254. Rubber &c. tubes; pipe joints. NORMAN A. E., and NORDAC, Ltd. Oct. 7,1949, No. 13012/47. Class 99 (i) and 99 (ii). A reinforced tube of ebonite, vulcanisable rubber, or other thermo-setting material, which is perforated and used for spraying or aerating corrosible liquids is manufactured by arranging an inner tube of the material on a mandrel, locating metal reinforcing strips 2 on said tube parallel to the axis and spaced symmetrically around the circumference, securing the ends of the strip by vulcanisable type, and wrapping an outer sheet of the material around the inner tube, the composite tube being then cured. Perforations 4 are formed in the spaces between the strips 2 and a thin strip of coloured rubber 5 may be embedded in the outer layer to indicate the position for drilling of the holes 4, and the end of the tube is thickened at 7 and threaded after vulcanisation. The strips 2, may be flat, Fig. 1, or curved to conform with the tube wall, and they may be of iron, steel, brass, or any rigid material which bonds with the ebonite or like material. A T-fitting may also be manufactured as above, using two mandrels and banding the reinforcing strips at the junction.

摘要： 551,528. Pumps and valves for corrosive fluids. SWINDEN, N., and NORDAC, Ltd. July 24, 1941, No. 9418. [Classes 8 (i) and 102 (ii)] [Also in Group XXIX] A pump or valve for corrosive fluids includes a deformable tube of rubber or like material the volume of which is varied by contracting and expanding its substance by direct compression and release therefrom in a direction parallel to its own axis. The deformable tube 10, Fig. 1, of a liquid pump is built up from a number of superposed bevelled rings 13 vulcanized to narrower surrounding steel restraining rings 14, and separated by thin steel washers 31 which are of the same diameter as the rings 14 and are rubber covered on their inner peripheries. The parts 13, 14, 34 are vulcanized together and to an upper flange 24 and a lower rubber-covered end plate 31, the latter being driven from a shaft 17 by a crosshead 20. The rings 14 may have eyes 36 to slide on vertical guide rods 37, and the tube 10 communicates with a rubberlined body 64. The latter has lateral connections containing automatic or mechanically operated rubber inlet and outlet valves and shock-absorbing air chambers 30. In a modified form, the inner instead of the outer wall of the tube 10 is capable of compression. Fig. 7 shows the upper part 39 of a valve chamber 42 constituted by such a deformable tube, Fig. 8, shows a tube 46 for a valve 45, and Fig. 10 shows a gas pump in which the tube is connected to the reciprocable end plate 53 of an ebonite plunger 54. Specification 542,040, [Group XXIX], is referred to.

摘要： 387,450. Tanks. CASTLE FIRE BRICK CO., Ltd., Northop, Flintshire, NORDAC, Ltd., Reno Works, Wealdstone, Middlesex, and ALLETSON, H. J., Ewloe Wood, Northop, Flintshire. Nov. 24, 1931, No. 32485. [Class 69 (i).] The walls of receptacles for corrosive fluids are built up of corrosion-resistant bricks or tiles bonded by a corrosion-resisting cement and having associated therewith reinforcing members of corrosion-resisting materials. The tiles may be formed of the acid-resisting fireclay of the Buckley district of Flintshire, and the reinforcing members may consist of metal coated with rubber, vulcanite, phenol-formaldehyde resin, or the material sold under the Trade Mark " Nordac." The reinforcing members 3, Fig. 2, may have a web entering recesses 6, or may be as shown in Figs. 3 to 6, and a covering of acid-proof material may be provided over the whole outer surface of the receptacle.
