Abstract: 1367318 Electrolytic purification of liquids BATTELLE MEMORIAL INSTITUTE 15 Sept 1971 [15 Sept 1970] 43076/71 Heading B1X [Also in Division C7] An electrolytic method of removing a dissolved or suspended constituent from an ionically conducting solution comprises selective absorbtion on conductive particles. It utilises a cell having two electrodes separated by a porous partition. At least one of the electrode compartments is provided with absorbent partides and means to agitate the solution so that the particles contact the electrode, become electrically charged and so permit selective absorption of the constituents. Container 1 is separated into two compartments 1A, 1B by porous PVC partition 2. Platinised titanium electrode 3A, graphite counter electrode 3B and saturated calomel reference electrode ER and connected to potentiostate PS. The absorbent particles may be iron or activated carbon. The solution is agitated by stirrer 5, by convection currents produced by a heater, or simply by rocking the container. In other embodiments the solution is recycled, if so the inlet and outlet ducts of the compartments may be provided with porous membranes to prevent the escape of the particles. The apparatus may be used for blood dialysis, desalination of sea water or for the absorption of gases dissolved in liquids.

Abstract: 1,163,331. Making heat exchangers; shearing; welding by pressure. D. DALIN. 30 Sept., 1966 [30 Sept., 1965], No. 43814/66. Headings B3A, B3R and B3W. [Also in Division F4] A method of making a heat exchanger comprises forming an elongated bimetallic strip having a core of good heat conductivity metal encased in a sheath of corrosion resistant material, forming the strip into a row of spaced apart, but connected fingers, welding the strip to a heat conducting wall of the exchanger with the strip fingers projecting from the wall as extended surface, and pressing the strip against the wall with sufficient force to compact the core metal. The strip is made from a copper or aluminium core with a stainless steel sheath and in one embodiment two adjacent strips are wound helically around a stainless steel tube 20. In an alternative embodiment, the heat conducting wall is flat instead of tubular. The inner bends 24 are connected to terminals 27, 27<SP>1</SP> of a source of welding current by electrodes 28, 28<SP>1</SP> so that the current flows through the intervening section of tube wall. The strips are pressed by tools which act after the welding operation, or the electrodes may be forced against the bends 24 after the flow of welding current is stopped. The strips may be flat or round, Figs. 4, 5 (not shown) and the extreme ends are sealed by the sheath material. Alternatively the strips may be made by passing a heated copper or aluminium ribbon 42 and heated stainless steel ribbons 41, 43 between rolls 46, 47, which initially compact the ribbons and turn in the edge portions of ribbons 41, 43. A second set of rolls 49, 50 bonds together the edge portions and the strip may be reheated for a shearing operation wherein an interleaved comb-like structure is formed. Rolls 51, 52 and 53, 54 have knife edges which shear the strip into a pair of combs (56) having interengaged teeth (57), Fig. 12 (not shown), and the rolls coact to shape the sheath so that the core is completely enclosed. The strip may also be sheared so as to form combs 60, 61, the latter having two rows of teeth, which may be aligned or staggered, and which are bent upwardly. The teeth of the comb 60 may be bent similarly. The comb 61 is secured to a tube 65 by projecting molten metal from a nozzle 66, the subsequent pressure being applied by a roller 67. Pairs of combs 60 are similarly secured, Fig. 27 (not shown).

IPC: C07C255/24
Filed: 1966-09-30
Abstract: Aminonitriles of the formula H2N-R-CN in which R is a substituted or unsubstituted alkylene radical, are obtained by contacting a mixture of ammonia and a lactam of the formula <FORM:1121038/C2/1> at 250-450 DEG  C. with a dehydration catalyst that gives an acid reaction in water.  The reaction is suitably carried out by passing a mixture of lactam vapour and gaseous ammonia over the catalyst which is in granular form. In the examples, o -amino capronitrile is prepared by reacting NH3 with caprolactam, employing as catalysts, a calcined mixture of phosphoric and boric acids and phosphoric acid on kieselguhr.  Small quantities of 5-hexenitrile are also produced.

Abstract: 1,066,656. Spray carburetters. SOCIETE INDUSTRIELLE DE BREVETS ET D'ETUDES S.I.B.E. Oct.18, 1965 [Nov.16, 1964], No.44063/65. Heading F1B. Mixture enrichment is provided by fuel supplied from the float chamber 4 through conduits 18, 19 via a suction actuated valve 21 to a jet 17 downstream of the choke valve 5. The height H of the jet 17 above the normal fuel level N is such that mixture enrichment occurs only at starting, when the choke valve is closed and the suction at jet 17 is therefore high, or at high speeds corresponding to nearly full load, when the air flow rate past jet 17 and therefore the suction thereat is high. As soon as the engine starts or as soon as the throttle 2 is closed at high engine speeds, the high suction downstream of the throttle acts on a diaphragm 23 to close the valve 21 whereupon mixture enrichment ceases. The carburetter may work in parallel during normal running conditions with a second carburetter having no choke valve, the first carburetter working alone during starting.

The flanges may extend away from both faces of web 11, containing a series of ribs 15, so that the formed grid may be fully encased in the material 20. Alternatively, the grid may be partially encased. The member 10, preferably made of extruded aluminium alloy, is deformed in a stretching machine in order to increase the distance between the flanges 12. A settable material, e.g. Plaster of Paris, Portland cement, Lignocellulose chips, or urea formaldehyde resin, is poured between the flanges so as to form when set a reinforced panel suitable as a wall panel. In a further embodiment, Figs. 5-7 (not shown), the member (24) has a constant cross-section comprising a central flange (25), edge flanges (26) and stiffening ribs (27) in the web 11, the ribs imparting resistance to bending at right angles to the plane of the web. In this case the openings 16 are made between the ribs and flanges such that the intermediate openings connect with the outer openings adjacent the edge flanges and so allow the bending of deformable ribs (31) to form a grid, Fig. 7, which is then treated with settable material to form a panel suitable for a ceiling.
