Title: Process for production of matrix molding board
IPC: B41C3/00
Filed: 1970-02-13
Abstract: 1,262,067. Matrix moulding boards. SUMITOMO BAKELITE CO. Ltd. 13 Feb., 1970 [15 Feb., 1969 (3); 27 Dec., 1969 (4)], No. 7067/70. Heading B6C. A process for the production of a matrix moulding board comprises mixing fibrous materials with a thermosettable resin such that the resulting mixture consists of chips of the materials impregnated with the resin. After drying, the chips are converted into fibres in a pulverizer or disc-refiner before dry-forming the resulting composition into a mat. A layer of a moulding mixture prepared from a thermosettable resin, which may be the same as or different from the first mentioned resin, and a filler is placed on one side of the mat before pressing the thus treated mat at 80 to 750 C., the compressed materials being in an intermediate condition such that, under heat and pressure, the thermosettable resin or resins can soften, flow and be converted into an infusible, insoluble form. Instead of treating the mat with a layer of moulding mixture a base sheet impregnated with the resin and filler may be applied to one side of the mat. The apparatus for making a matrix using the board may comprise two hot platens between which are placed the board, an original forme and a metal plate which may be of wire netting or a perforated and grooved plate. The thermosettable resins employed may be phenolic, amino, epoxy or unsaturated polyester resins. The fibrous material may be asbestos, synthetic and regenerated fibres, yarn, cotton wool, rock wool, glass wool, wood pulp, cotton pulp and rayon pulp. Paper chips may also be used. The filler may be powdery silica, alumina, calcium carbonate or wood flour.

Filed: 1967-02-20
Abstract: 1,139,536. Two-for-one twisting machines, singeing yarns. PALITEX PROJECT-Co. G.m.b.H. 20 Feb., 1967 [21 Feb., 1966], No. 7901/67. Headings DID and D1F. A two-for-one twisting machine has provision to singe the yarn. Yarn 1 from a spool 2 is drawn off upwardly and passed downwardly through a spindle 3, leaves the spindle radially between a cage 4 and a balloon limiting device 5, passes through a guide ring 13, around a stripper 12, over a guide 6 and is wound by a traversing mechanism 7 onto a package 8 driven by a friction roller 9. Between the ring 13 and a guide eye 19 the balloon of yarn passes through the gas flames of a singeing device 11. The device 11 may be of arcuate shape (Fig. 2, not shown), circular shape (Fig. 5, not shown) or may be an electrically heated ring (Fig. 6, not shown) with a polygonal shaped inner surface whose flats contact the yarn. In Fig. 10 (not shown) the yarn is singed above the guide 19 where it is caused to revolve in a inverted cone orientation by a guide (24) on a plate that is driven by a friction wheel. In Fig. 11 (not shown) the rotation is cylindrical and is caused by two guides driven by the friction wheel. In Fig. 12 (not shown) the singeing device is a roller with gas jets driven in the opposite direction to the passage of the yarn. In Fig. 13 (not shown) the roller is electrically heated and in Fig. 14 (not shown) the electrical heating is radiant so that only the portion of the roller over which the yarn passes is heated. In Fig. 15 yarn 44 from a stationary package is drawn upwardly through a rotating spindle 45, radially outwardly and then downwardly through a tube 49 to be wound by a traversing mechanism 51 onto a package 52 that does not rotate with the spindle 45. In Figure 17 yarn from a stationary package 2 is drawn upwardly through a rotating spindle 61 from which it passes radially to a rotating guide 66. The package 2 is maintained stationary magnetically. Fig. 18 (not shown) shows a similar arrangement in which the package rotates. The guide ring 13 (Fig. 3, not shown) is in three pieces with a ceramic facing 14. The stripper 12 is a roller with slot of zig-zag formation around which the yarn passes.

Title: Process for the elimination of iron from aqueous liquors
Inventor: FLETCHER ARCHIBALD WILLIAM
IPC: C22B3/32
Filed: 1963-02-27
Abstract: Ferric iron is separated from aqueous solutions containing it in a concentration of not more than 4g./l. and other metal values by contacting the aqueous solution, at a pH not less than 0.5 of a pH unit below the pH of hydrolysis of the iron salt in solution, with a solution in an organic solvent of one or more saturated aliphatic monocarboxylic acids having from 8 to 11 carbon atoms and separating the aqueous and organic phases obtained.  At higher initial Fe3+ concentrations, say 20 g./l., it is necessary to reduce the iron concentration by conventional methods, e.g. precipitation with alkali, before applying the process of the invention.  The pH of the aqueous solution is adjusted with alkali immediately before extraction.  The raffinate may be extracted repeatedly and the iron-loaded organic phase may be contacted with dilute acid, e.g. H2SO4 to regenerate the organic reagent which is then recycled. Specified acids are 2-ethyl hexanoic acid, pelargonic acid and Versatic acid, Versatic is a Registered Trade Mark, a mixture containing a ,a 1-dialkyl propionic acids, for which kerosene is a suitable solvent. Comparatively high quantities of iron may be removed from solutions also containing Cu and Ni by precipitating Fe(OH)3, substantially free of Cu and Ni at pH 2.5 and removing the remaining iron by extraction.

B l o w i n g ; delivering molten metal.-In a rotarytable machine, of the type described in Specification 23478/11, in which the parison moulds are raised into the blow-moulds for the filling and pressing operations, two or more parison moulds are combined with each blowmould and are arranged to come into action on alternate or successive revolutions of the machine. As shown, the parison moulds c, Figs. 1 and 2, carried by the lower part a<1> of the rotating table are arranged in pairs, each pair being carried by a plate c<x> on a pivoted arm c<1> connected by an adjustable safety link d' to a crank d. A disk e on the axle of the crank carries rollers e<1> which engage stops on a bracket e<2> during the rotation of the table, so that the crank is turned through half a revolution and the moulds c changed over. The parison mould is raised by a lever f, Fig. 5, operated by a cam t<4> on a side shaft h<2>, and a trigger g supports the mould while it is charged with glass from the device r. At the pressing position a dog h, Fig. 3, operated by a cam h<1> on the shaft h<2> holds the mould c against the shoulder of the blow-mould b. A pivoted spring-pressed wedgeshaped tongue i co-operates with the dog h so that, if a mould c is down, the tongue yields, but with the mould in proper position, the lower end of its stem c' rides over the tongue. i and the trigger g is thrown back by contacting with a roller g<2>.
