Abstract: 220,309. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Wensley, R. J.). Aug. 6, 1923, [Convention date]. Drawings to Specification. Selective distant control systems and apparatus; order apparatus.-In a system for supervising from a remote point the operation of a number of apparatus units at a substation, by the transmission of a signal over a trunk extending from the substation to the control office, means are provided for repeatedly selecting the supervisory signal at the control office on its failure to operate. The invention is described with reference to a system for controlling and supervising the automatic substations of an elec. tric supply system, similar to that described in Specification 216,085 with the exception that whereas in the previously-mentioned Specification the sending apparatus at the control station is held in use over a circuit including an actuated pair of springs of the control key, (which remains in the, position last operated until it is automatically released on the desired operation taking place) in the present system the control key is only thrown momentarily and causes the energization of one of two relays, which locks up over a circuit including a pair of normally-closed springs on the opposite side of the key and holds the signal-sending apparatus until the desired operation is effected and this relay unlocked. The holding relays also close circuits for monitoring lamps. The operator may release the sending apparatus at any time by momentarily throwing the key to the other side and thereby unlocking the holding relay. Two modifications are described in which a single holding relay and a single monitoring lamp are provided for each key.

Title: Method for the production of amido sulphonic acid
IPC: C01B21/096
Filed: 1948-07-13
Abstract: In making amido-sulphonic acid by hydrolysing ammonium imido-sulphonate with or without ammonium - nitrolo - sulphonate and separating crystals of the acid, the hydrolysis is carried out at an elevated temperature, e.g. at about 50 DEG  C., in sulphuric acid solution of such concentration that after separating the amido-sulphonic acid crystals, the mother liquor contains at least 50 per cent sulphuric acid.  Where ammonium nitrilo-sulphonate is present, it is first hydrolysed to the imido-sulphonate in solution in water or dilute sulphuric acid, and the imido-sulphonate is then hydrolysed as above.  After hydrolysis the mixture may be allowed to cool and stand for some hours before suction filtration of the acid crystals which may be washed with a saturated aqueous solution of amido-sulphonic acid. According to the prior art, amido-sulphonic acid has been produced from ammonium imido-sulphonate by hydrolysis in weakly acid solution saturated with ammonium sulphate, followed by neutralization with ammonia gas, the solution after separation of amido-sulphonic acid being worked up to yield further amido - sulphonic acid and ammonium sulphate (vide German Specification 564,123).  In another process, solid or dissolved salts of amido- or imido-sulphonic acid are treated with excess nitric acid or determined concentration, use being made of the low solubility of amido-sulphonic acid in 50-60 per cent nitric acid by adjusting the concentration of the acid to give this concentration in the reaction liquid after precipitation of the amido-sulphonic acid.

Filed: 1971-06-04
Abstract: 1303961 Coated microporous film CELANESE CORP 4 June 1971 [4 June 1970] 18919/71 Heading B2E An air-permeable and waterproof sheet material comprises an open-celled microporous film of a polymer having a crystallinity above 30%, in which film the pore size is less than 5,000 Angstrom units, and on at least one face of the film a layer of filamentary polymeric material of varying crystallinity and diameter bonded to itself at filament crossing points and to the film at a multiplicity of points over the face of the film so that the said face possesses both the appearance and feel of a textile fabric. The sheet material may be produced by forming an elastic film from the polymer having a crystallinity of 30%, rendering the film porous by stretching and annealing it and before or after the stretching and annealing, spray spinning a molten polymer as a continuous filamentary material and depositing the filamentary material while still tacky on to at least one face of the film. The polymers from which the open-cell films may be formed may be olefin polymers or copolymers, especially isotactic polypropylene, oxymethylene polymers and copolymers, preferably copolymers of trioxane and cyclic ethers containing at least two adjacent carbon atoms, polyalkylene sulfides, polyarylene oxide, polyamides, and polyesters. The film may be produced by extrusion, preferably with rapid cooling and rapid draw-down to obtain maximum elasticity. Before being converted to porous film the extruded film may be heattreated or annealed to improve its crystal structure. The film may be rendered porous preferably by first cold stretching and then hot stretching. After the stretching operation the stretched film may be heat-set. The preferred filamentary polymeric material are the polyolefins, especially polypropylene. Other polymers mentioned include polyethylene, cellulose acetate, polyamides, oxymethylene polymers, polyalkylene sulfides, polyarylene oxides and polyesters. The extrusion orifice may be such as to produce filaments of round or oval cross-section, or of trilobal cross-section. The film may be moved between two or more spray spinning orifices so that the filamentary material is received on both faces of the film. A plurality of spray nozzles may be positioned to project filamentary material on to the film surface in overlapping patterns and/or back and forth relative movements in a lateral direction may be effected as between the spray nozzle and the film so that the spray pattern traverses back and forth across the width of the film. The products may be calendered to improve their fabric-like properties, preferably at such temperatures that no additional thermal self-bonding of the filamentary material occurs.

Abstract: 1409410 Isostatic compaction NATIONAL FORGE CO 30 April 1974 [11 May 1973] 18932/74 Heading B5A A method of isostatically pressing a porous body, e.g. of metallic powder 48 in a plastic can 50, comprises heating the body to a temperature above that at which it is compressed and below its fusion temperature, inserting it in a pressure vessel 12 which is then closed and sealed by a plug 14, rapidly pumping liquid pressurizing medium into the vessel to fill it while avoiding contact of the liquid with the body until the vessel is substantially filled and then rapidly increasing the pressure, by pumping, to a level above the critical pressure of the liquid. The body is placed in a shielding container 38 whereby the pumped liquid fed through a port 20 overflows the container to contact the body when the space in the vessel is almost full; a pressure release device 36 is provided. On pressure release, the liquid is drained through a port 20, and liquid surrounding the body vapourizes. In a modification a cylindrical heat sink is located between the body and the shielding container and transfers heat to the body after the body is placed in the container. In Fig. 7 the body 80 is mounted on a support 74 and pressure liquid is fed tangentially to the pressure vessel wall through an inlet 72 ensuring that it does not contact the body until the vessel is substantially full. In Fig. 9, not shown, the liquid is supplied to a cylindrical pressure vessel via an inlet central of its base, and the vessel is rotated to centrifuge the liquid outwardly and upwardly along its wall.

Title: Preparation of sulfo esters of ª‡-methylene carboxylic acids
Inventor: SHEETZ DAVID PATRICK
IPC: C07C309/12
Filed: 1966-05-03
Abstract: Sulpho esters of a -methylene carboxylic acids are prepared by direct esterification of an hydroxy aliphatic sulphonic acid with an a -methylene carboxylic acid using sufficient of the a -methylene carboxylic acid to esterify the hydroxy sulphonic acid, followed by azeotropic removal of the water formed or present. From 3 to 10 mole proportions of the a -methylene carboxylic acid per mole of hydroxy sulphonic acid are advantageously employed. Suitable a -methylene carboxylic acids include those of the formula CH2=C(R)-CO2H, where R is hydrogen, halogen or an organic radical such as alkyl, and suitable hydroxy aliphatic sulphonic acids include those of the formula HO-Q-SO3H, where Q represents a bivalent organic radical in which the -OH radical is attached to an aliphatic carbon atom.  The reaction is advantageously carried out at subatmospheric pressure, preferably in the range from 20 to 200 mm. of Hg and at a temperature between 50 DEG  and 175 DEG  C.  A polymerization inhibitor is usually added.  The monomeric sulpho esters of mixtures thereof may be homopolymerized or copolymerized. The polymerization is accelerated by heat, by activation with ionizing radiations and by catalysis with free-radical producing materials such as a ,a 1-azobisisobutyronitrile and peroxygen compounds.  The polymers are used as soil conditioners, stabilizers for aqueous colloidal dispersions and emulsions, surfaceactive agents, antistatic finishes for textiles and plastics, adhesives, sizes for textiles and paper, and dye assistants.  The monomers have similar uses and are polymerizable in such compositions.
