Title: Improvements in and relating to wire connectors
IPC: H01R13/115
Filed: 1940-03-28
Abstract: 539,811. Two-part couplings. UNITEDCARR FASTENER CORPORATION. March 28, 1940, Nos. 5620 and 5621. Convention dates, March 31, 1939 and April 1, 1939. [Class 38 (i)] A wire coupling comprises a socket-like member attached to one wire and a co-operating flat or cylindrical terminal attached to the other wire each having means for gripping the insulation of the wire and a portion for securing the wire conductively to the socket, this portion being exposed for access with a soldering iron or spot-welding electrode. In one form the socket 5, Fig. 9, is flattened and contains a spring member 22 that presses the co-operating terminal 24 against the upper part 13 of the socket. A pair of claws 20 bent up from opposite sides of the shank 10 of the socket grip the insulation 1 of the wire 4, and the bared end of the wire lies upon an exposed surface 21 of the shank and is soldered or spot-welded thereto. The terminal 24 is formed with shoulders 38, Fig. 7, which engage behind ears turned down at opposite corners of the edge 17 of the socket. Dis-engagement is effected by pressing down the end 37 of the terminal against the action of the spring- member 22 and if the coupling is enclosed in a rubber sleeve 7 a protuberance 39 marks the point at which pressure should be applied. In a modification, the socket 47, Fig. 13, is formed on the opposite side of the base 42 to the claws 49 and the wiresecuring surface 46, and the spring member 52 presses the terminal 60 against the base 42 and has a projection 53 that engages a hole 62 in the terminal to retain it. The terminal is released by a direct pull. In a further modification the socket 65, Figs. 22, 23 is cylindrical and resilient and has a depression 74 constituting a retaining means for engaging an annular groove 82 in the ferrule 77 that forms the co-operating terminal. The groove 82 corresponds to an internal rib 81 that grips the insulation of the wire 2, the bared wire 4 being exposed through an opening 78 so that it can be secured by solder.

Abstract: 780,308. Blasting devices. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Sept. 19, 1955 [Feb. 25, 1955], No. 5676/55. Class 9(1) A package for use in blasting operations comprises a cylindrical waterproof container enclosing two non-explosive charges which are kept apart until the package is to be used and when mixed form an explosive. One charge is predominantly ammonium nitrate and the other consists of particles of a solid fuel which may be finely divided dried organic material such as wood, cork dust, charcoal, cereal meals, peat. lignite, coal or anthracite. Paint fine aluminium powder may be mixed with the fuel. The container 1 may be a metal cylinder containing the ammonium nitrate 5 and a rubber bag 4 filled with the fuel 6. A cup-shaped lid 2 closing the package is secured by an adhesive strip 3. To use the package, the bag 4 is taken out and its contents poured into the ammonium nitrate. The lid 2 is replaced and the packet shaken to mix the contents. In the arrangement of Fig. 2, the fuel 6 is separated from the charge 5 by a stretched membrane 10 adapted to be pierced by a pin 9 projecting from the lid 2, when the lid is forced downwards. During storage a stop 7 prevents movement of the lid. The explosive mixture obtained on mixing the charges may be 90 per cent ammonium nitrate, 5 per cent aluminium and 5 per cent bagasse, all parts being by weight. Specification 780,309 is referred to.

Title: Manufacture of new esters of 4-sulphophthalic acid or its substitution products
IPC: C07C303/22
Filed: 1940-04-01
Abstract: 540,095. 4-Sulphophthalic acid esters. SOC. OF CHEMICAL INDUSTRY IN BASLE. April 1, 1940, Nos. 5811 and 5812. Convention dates, April 4, 1939, and March 4, 1940. [Class 2 (iii)] 4-Sulphophthalic acid and substitution products thereof are esterified on one carboxyl group with 2-ethyl-butanol and on the other carboxyl group with an alcohol containing at least four carbon atoms. Suitable alcohols mentioned include butyl-, isobutyl-, amyl-, n-hexyl-alcohols, 2-ethylbutanol-(1), methyl propyl carbin-carbinol, 2-ethyl-hexanol-(1), methylcyclohexanol, and decyl-, dodecyl-, hexadecyl-, octadecyl-alcohols. Instead of the free acid there may be used the corresponding anhydrides, acid halides, and esters. In the. latter case a re-esterification takes place. A salt of the sulphonic acid may also be used. In this case a slightly higher temperature is employed and promoters such as gaseous hydrochloric acid or concentrated sulphuric acid may be present. The esterification is also assisted by removal of water from the re-action mixture in any known manner and particularly with the assistance of a substance which forms an azeotropic mixture with water such as benzene or toluene. The esterification may also be conducted under pressure. In examples : (1) Phthalic acid is sulphonated with sulphur trioxide and the product so obtained is esterified, in the presence of sulphuric acid first with 2-ethylhexanol and then with 2-ethylbutanol to give a colourless solid mass which is a good framing agent. (2) 4-Sulphophthalic anhydride is treated with 2-ethyl-butanol-(1), and the product neutralized with caustic soda. (3) As in example (2) using a lower esterification temperature. The products of the invention are useful as wetting agents and may be used alone or in combination with solubility improvers such as urea or sodium cymene sulphonate, or soaps, protective colloids, dressing agents, weighting agents, softening agents or matting agents. In particular in admixture with fat solvents such as pine oil, methyl-cyclohexanol, or tetrahydronaphthalene products with a good wetting action are obtained. Specification 481,346 is referred to.
