Filed: 1948-12-20
Abstract: 656,004. Two-part couplings. DOANE, L. C. Dec. 20, 1948, No. 32885. Convention date, Dec. 20, 1947. [Class 38 (i)] A vapour - proof plug - and - socket connector comprises a socket member having a body 21 provided with openings 44 through which project the plug pins 29, 30 and with a uniformly thick flexible insulating diaphragm 45 with self-closing apertures 47 in alignment with the openings 44. The body 21 also receives a yieldable base-member 48 in which are mounted the split socket contacts 49 which are pressed on by the base member which has recesses adjacent thereto to form chambers for quenching the arcs as the plug pins are withdrawn from the socket contacts. The plug body 20 carries an insulating base 32 for the pins which are surrounded at their lower ends by a flexible corrugated washer 34 of which the corrugations 35 are flattened when the plug-and-socket connector is assembled. A spring. clip 36 in a groove 37 on the plug body retains the connector parts together by engaging projections 42 on the socket body 21, the plug body being grooved to accommodate them. To completely seal off the plug cable 22, an extension 23 on the plug body is provided with bushings 25 acted on by a screw plug 24. The apertures 47 terminate the conical projections 46 in the diaphragm 45, and may be either round or flat, Figs. 13, 16 (not shown). The connector can also be made liquid-tight by placing a concavo-convex flexible washer 110 with its projections facing outwards in the body of the socket member between rigid discs 112, 114 apertured for the plug pins, Fig. 15. Several socket members may be mounted in a single casing provided with plug ejectors and a hinged lid and a magnet on the base of the casing to retain it in position on steel surfaces (Figs. 9, 10, 11, not shown).

Title: Improvements in the manufacture of ª‡-chlor-ethyl-benzene and related compounds
IPC: C07C17/08
Filed: 1932-11-24
Abstract: a -Chlorethylbenzene is produced by the addition of hydrogen chloride to styrene in the presence of substances capable of forming loose addition compounds with hydrogen chloride, which compounds are again readily split into their components.  Suitable substances include methyl and other alcohols, acetone, dimethylaniline and other amines especially tertiary amines and water in the presence of an emulsifying agent.  In examples (1) hydrogen chloride is passed into a solution of styrene in xylene containing dimethylaniline, methyl alcohol or butyl alcohol, acetone or water in the presence of dibutylnaphthalene sulphuric acid and polyglycerine.  The solution of styrene in xylene may be replaced by solvent naphtha containing styrene obtainable by fractionating crude coke oven benzene.

Title: Improvements in or relating to the production of pseudo-alloys
IPC: C22C1/04
Filed: 1947-12-29
Abstract: A method for producing sintered bodies of two or more metals which do not alloy with each other in the liquid state consists in reducing metal compounds, in the form of mixed crystals which contain the said metals in proportions corresponding to the desired composition of the alloy to be produced, to metal mixtures under such conditions as to avoid separation of the metals, and compressing and sintering the metal powder mixture so produced.  Thus copper-iron alloys may be formed from chalcopyrite by desulphuration followed by reduction pressing and sintering.  Alternatively the copper-iron mixture may be formed by reduction of mixed crystals of copper chloride and iron chloride with hydrogen.
