Title: Improvements in the working up of materials containing lead
IPC: C03C1/00
Filed: 1934-12-11
Abstract: Lead silicates or frits or glazes containing them are obtained from sulphur-containing lead ores, dressing or smelting products, or accumulator sludge by heating them, after conversion of any sulphide present to sulphate, in the presence of reducing agents which reduce the temperature of reduction of the lead sulphate to 800--1000 DEG C. and remain inactive at low temperatures, the remaining constituents of the glazing batch, when glazes are to be produced, being added before or during the reduction of the sulphate.  Suitable reducing agents are metal carbides, silicon carbide, aluminium, or sulphides, but graphite powder may also be used.  The reducing agent may be added in portions as the reaction proceeds or be used in grains of varying sizes to regulate the speed of reaction.  Two or more reducing agents operative at different temperatures, for instance sulphides and carbides, may be used together.  Oxidation of sulphides present in the initial material may be assisted by means of oxidizing agents such as ammonium, potassium, or sodium nitrate, or barium peroxide.  In preparing glazes, the mixture of the necessary constituents may be heated to the fusion temperature of the glaze in the fritting furnace, or be applied to a ceramic body as a crude glaze by firing.  In the latter case, oxidation of sulphides may first be effected in an oxidizing atmosphere, and reduction be then effected in a reducing atmosphere.  The process is effective for destroying sulphates of other metals present in the glazes. Examples relate to the production of lead monosilicate from a mixture of accumulator sludge, sand, and silicon carbide, of a white ware frit from a slime containing 50 per cent each of lead sulphide and silica, by roasting the slime and heating the roasted material with chalk, feldspar, boric acid, and silicon carbide, and of a crude pottery glaze from galena, feldspar, sand, and silicon carbide.
Patent GB-972459-A (GB)
Title: Improvements in or relating to the manufacture of confectionary products by extrusion
IPC: A23G3/42
Filed: 1962-09-18
Abstract: A confectionery product (candy) is made by subjecting a mixture of starch, a sugar, and water to simultaneous heat pressure and shearing action by means of a hot extrusion step thereby effecting a dissolution of the starch product and sugar with simultaneous mixing and mastication of the mixture with the resulting formation of a shape retaining plastic confectionery mass.  The starch products include dextrins derived from corn, high amylose corn, sago, wheat, rice, sweet potatoes, sorghum, waxy sorghum, waxy maize, potatoes, tapioca, and amylose, amylopectin and their acetate esters and other edible derivatives.  Sugars include dextrose, levulose, sucrose, lactose, maltose, sorbitol, and mannitol.  The starch product comprises 300% to 10% by weight of the sugar content.  Up to 50% plasticizer (based on the combined weight of starch and sugar) such as the polyhydroxy alcohols, glyerine and sorbitol, may be added to improve the plasticity of the mix.  Other additives include colour, flavouring, humectants, preservatives and acidifiers.  The inherent water content of the sugar starch mix may be sufficient to provide a mouldable mass, but water may be added to bring the content to 25% for soft candies.  The starch product and sugar are mixed together, the p  plasticizer and other water dispersible additives are dissolved in water, and sprayed on to the sugar-starch mix which is thoroughly agitated.  The resulting mass is pelletized and fed to a heated screw extruder (180 DEG -360 DEG F.) where it is subjected to heat, shear and pressure and extruded into shapes.  A torpedo head may be fitted into the extruder screw to obtain more intimate mixing.

Title: Fuse structure
IPC: H01H85/42
Filed: 1964-09-01
Abstract: 1,022,224. Fusible cut-outs. WESTINGHOUSE ELECTRIC CORPORATION. Sept. 1, 1964 [Sept. 30, 1963], No. 35747/64. Heading H2G. A high voltage fuse, comprising an elongated insulating tube 13 with end terminals 14, 15, has separate means for interrupting high and low currents. Fuse elements 16 are connected between an arcing tube 22 and a terminal block 29 and when they are fused, the arcing rod is pulled to the right by a spring 26, and a pin 25 actuates the ejection mechanism of the fuse unit. Contact is maintained with the arcing tube 22 by fingers 35a embraced by a spring 38. If the current is large, an arc is drawn out to the end of the tube 22 in the annular space between a gas-evolving tube 28 and gas-evolving ring blocks 17 and the resulting gas passes through the opening 21. The tube 28 may be formed with a spiral groove in its outer surface to increase the length of the arc, Fig. 5 (not shown). Corona discharge is minimized by the relatively large diameter of the arcing tube 22, by a corona tube 18 with an in-turned end 18a to grade the electrostatic field, and by a corona shield 39. If the current is small, it is passed for an instant by a fixed conductor 31 initially engaged by a conductor 34 which is secured to the right end of the arcing tube- 22. As the arcing tube 22 moves to the right, the conductors 31 and 34 separate and an arc is drawn in the bore 40 of the tube 28. With a high current, the conductors 31 and 34 fuse simultaneously with the elements 16.

Abstract: 904,431. Copy-milling. HAYES ENGINEERS (LEEDS) Ltd. Oct. 6, 1960 [Oct. 26, 1959], No. 36166/59. Class 83 (3). An hydraulic valve unit comprises a hollow valve element 2 and a stylus carrier 9 laterally movable in a housing 3, and a series of plungers 29 arranged to operate the element and being controlled by hydraulic pressure regulated by a part 15 of the stylus carrier. The element is restrained from axial or angular movement by a flange 4 running between balls 5, the degree of freedom being determined by balls 32 adjusted by a sleeve 31 and a nut 30. The flange is urged by spring-pressed plungers against the rods 7 of two valves, each controlling an hydraulic motor. The stylus carrier 9 passes through the element and has a flange 10 guided by balls 11 and centralized by spring- loaded plungers. The stylus 13 is mounted in a socket 12 which can move laterally a predetermined distance before deflecting the element. The control part 15 is mounted by a selfaligning ball bearing and is surrounded by twelve chambers 17, each bearing an inlet port 19b slightly smaller than an outlet 18. The inlet port 19b is formed in a plunger 19a but may be formed simply by an orifice 19. Fluid leaving the outlets is confined by seals 24, 25 and exhausted through a pipe 26. The direction of movement of the element 2 is determined by the particular one of the chambers 17 to which each plunger is connected, closure of a chamber 17 by the part 15 causing movement of the associated plunger 29 towards the element. The connections between the chambers 17 and the plungers 29 may be mounted on a rotatable ring to enable the direction of traverse of the cutter to be altered relatively to the direction of the template or, by partly moving the ring, to render the tracer inoperative. The carrier 9 may be hollow and contain an axiallymovable rod for a depth control valve.

Title: Process for the recovery of copper
IPC: B01J41/00
Filed: 1957-11-22
Abstract: Brine from a dicyanobutene synthesis which contains cuprocyanide ions is acidified to precipitate the major part of the copper as cuprous cyanide, which is separated, and the liquor passed through an anion exchange resin in the chloride form.  The loaded resin is then eluted with a solution containing cyanide ions to give an eluate containing cuprocyanide ions, the resin is regenerated with a solution containing chloride ions and the process repeated.  In the preferred process, the copper-containing brine is brought to a pH of 1.5 \sB 0.5 with hydrochloric acid, heated to 30-75 DEG  C. and passed through a bed of strongly basic anion exchanger containing quaternary ammonium groups.  If desired the bed may then be washed with soft water to prevent darkening of the products due to HCN polymerization. When copper begins to increase in the effluent, the bed is eluted with a 5-7 N alkali metal (e.g. sodium) cyanide solution, whereby an alkali metal cuprocyanide solution of increased concentration is obtained and the temperature of the bed rises e.g. to 85-95 DEG C. due to the reaction.  The bed may then be washed with water again, and the cyanide ion displaced by means of 1-5 N brine.  The latter may be supplied in the form of filtered acidified brine from dicyanobutene synthesis, before or after removal of copper by anion exchange.  When using untreated copper-containing brine, one or two bed volumes are utilized to regenerate the chloride form of the resin and the resultant effluent containing copper passed to other parts of the cyanobutene synthesis: thereafter the copper content of the effluent drops and the continued passage of the brine results in absorption of copper as before.  It is preferred to use downward flow through the bed of exchange resin in each of the absorption and elution steps and to prevent channeling a backwash of soft water may be employed after downflow washing of the bed following elution with the cyanide solution.
