Abstract: 1,125,993. Cupric oxychloride. INSTYTUT PRZEMYSLU ORGANICZNE GO. 24 Jan., 1967 [24 Jan., 1966], No. 3433/67. Heading C1A. Cupric oxychloride is produced from metallic copper by preparing a solution of a complex of cuprous chloride and a chloride of an alkali metal by means of a free chlorine containing gas and oxidizing said complex by means of a free oxygencontaining gas, the solution of the complex being passed through an impeller-type pump to which the free oxygen-containing gas is simultaneously supplied. Usually, the free oxygen-containing gas is air. Preferably, suction is applied to the free oxygencontaining gas by means of the impeller pump. In an example, as shown, the column 1, in which a solution of the cuprous complex Na 2 CuCl 3  is formed by reaction of metallic copper scraps with a mixed solution of cupric chloride and sodium chloride, and the impeller pump 2 form an internal cycle in which the solution circulates, chlorine being added if necessary from 7 to maintain the optimum concentration of cupric chloride. A portion of the solution is drained to an outer cycle consisting of impeller pump 4, column 5 and selfacting suction device 3. Air is continuously sucked through the solution. Cupric oxychloride is removed by the filter assembly 6 and the solution returned to the internal cycle through pump 2.

Abstract: 398,210. Separating solid materials. COOK, J. A., 101, Bayswater Road, West Jesmond, Newcastle-on-Tyne. Feb. 5, 1932, No. 3487. [Class 117.] Apparatus for separating mixtures of materials the constituents of which, such as coal and stone, have different rolling or sliding velocities on an inclined surface, comprises a number of such surfaces each of which has a wide gap at its lower end and one or more narrower gaps between it and the upper end. The surfaces are disposed so as to provide a progressive separation of the constituents. The Figure shows an arrangement for separating the products of a grader A such as described in Specification 396,748. The separator B comprises two parallel inclined surfaces 1, 4 and four parallel oppositely inclined surfaces 2, 3, 5, 6, preferably perforated to increase friction. The surfaces are provided with gaps 1d, lc, 2c at their lower ends of such width that only the faster moving constituent, e.g. coal, can jump across to discharge shoots C<1> .. C<6>, the remaining material falling through the gaps either into discharge bins S<1> .. S<4> or on to another surface for further treatment. Above these gaps are disposed narrower gaps 1b, 2a, 2b by which the slower moving constituent, e.g. stone or a product containing it, is passed to the discharge bins. Preferably guide plates are provided at the gaps where the stream changes direction in order to break its fall, and the lower edge of the gap may be bevelled or lipped inwards. In a modification the surfaces 2, 3, 5, 6 may lead on to a further surface parallel to the surfaces 1, 4, and the bins for collecting the stone may be adapted to discharge at both sides of the apparatus.

Abstract: 877,141. Making heat exchanger panels; stamping. OLIN MATHIESON CHEMICAL CORPORATION. Feb. 2, 1960 [Feb. 18, 1959], No. 3696/60. Classes 83 (2) and 83 (4). A method of fabricating a roll forged panel for refrigerator heat exchangers comprising interposing a weld - preventing material between superimposed metal sheets in a predetermined pattern of passageways and welding said sheets in their areas not separated by said weld preventing material is characterized in that the width of the applied weld inhibiting material 2 for each passageway 3 is in excess of the width required for distension of the desired configuration of the passageways, a restraining force being applied over the area of excess weldinhibiting material whilst the remaining unwelded portions of the panel are distended by pressure. The restraining force is effected by dies 6 and 7, the die 6 being recessed to impart the desired configuration, e.g. triangular, semicircular or rectangular to the expanded passages. The method gives added resiliency to the panel to withstand sudden pressure surges in the passageways. In a modification, the panel is expanded between unyielding platens 13 and 14, Fig. 8, with inserts 15 interposed between the platens and the excess width of weldinhibiting material 9. In a further modification, the lower inserts are dispensed with and inserts 16 of circular cross-section, Fig. 9, are substituted for the upper inserts. Specification 759,804 is referred to.

Filed: 1974-01-30
Abstract: 1433083 Slub yarns MITSUBISHI RAYON CO Ltd 30 Jan 1974 04222/74 Headings D1F and D1W A process for continuously producing slub yarns comprises passing a multifilament yarn 1 through a reduced pressure region produced by sucking air from atmosphere through the region. Apparatus for carrying out the process comprises a hollow column 12 having end plates 13, 15 with yarn supply and delivery holes 14, 16 respectively open directly to the atmosphere, the periphery of the column 12 being connected to a vacuum source via a pipe 17, and the apparatus including feed and delivery means arranged to deliver the yarn from the column 12 at a slower rate than the feed rate. Air is sucked from the atmosphere through the column 12 via the holes 14 and 16, and creates a turbulence in the column which forms the slubs 7a on the yarn. An air permeable partition may be aranged in the pipe 17 or in the column 12 between the yarn path and the pipe 17 so that the yarn is sucked against the partition to increase the agitation of the yarn. In a further embodiment. Fig. 8, a yarn storage inner hollow column 42 is provided fixed to the end plate 13 and provided with holes 43 at the yarn entry end; the holes 43 may be arranged so that their axes do or do not intersect the axis of the column 42. An air vortex hollow column 52 is preferably also provided extending from an air suction device 45 adjacent the other end plate 15. The column 52 is provided with peripheral holes 56, the axes of which do not intersect the axis of the column 52. Air is sucked through holes 47 in the device 45 into the column 52 where a vortex is created as the air leaves via holes 56. The multifilament yarn is agitated and the slubs formed in the column 42 by virtue of the holes 43. In a further embodiment the air vortex column 52 may be omitted, but the air suction device 45 is provided adjacent the end plate 15. The yarn may be comprised of a single multifilament yarn or a plurality thereof, either the same or different. In the case of different multifilament yarns being used, they are preferably thermoplastic polymer yarns one of which has a lower melting point than the other, and the slub yarn is heat treated to bond the yarn due to melting of the lower melting point component. A heat treatment may be used to effect tightening of the stub yarn by shrinkage of the component filaments. The yarn may be crimped as by gear crimping or false-twist crimping before or after slub formation. The yarn may be entangled by an air jet prior to entry into the reduced pressure region; or the slub yarn may be treated with an air jet after slub formation to consolidate the yarn. The yarn may also be given a fluffy appearance by the presence of abrasive particles on the inner surface of the column 12 or the hollow column 42.
