Abstract: 985,887. Spinnerets. MONSANTO CO. June 24, 1963 [June 25, 1962], No. 24995/63. Heading B5B. A spinneret suitable for making conjugate filaments comprises a spinning head 11 having concentric annular chambers 12, 13, 14 which are separated by concentric annular walls 17 18 tapered to knife-edges at their outer ends, and a spinning plate 19 secured thereto provided with a pair of concentric annular V-shaped ridges 24 and 25 the apices of which are engaged by the walls 17 and 18. The apex of each V-shaped ridge is provided with a plurality of spinning orifices 27, conically counterbored as at 28 (Fig. 3) to provide for a free flow of the spinning solutions past the knife edge. A first spinning solution is fed through bores 30, 31 from a source 32 into the chambers 12, 14. A second spinning solution is fed through a bore 35 in the head 11 from a source 36 to the annular chamber 13. The two spinning solutions flow past the tapered ends of the walls 17 and 18 and exit through the spinning orifices 27 as conjugate filaments. The V-shaped ridges prevent bulging of the plate 19 under pressure, and consequent separation from the walls 17 and 18. Hence accurate control of the flow of the two spinning solutions to the orifices 27 is ensured.

Abstract: 411,002. Photo electric cells. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. Sept. 9, 1933, No. 25034. Convention date, Dec. 31, 1932. [Class 39 (i).] A cell having a photoelectric electrode with an adsorbed layer of alkali metal, contains a quantity of one of the alkaline earth metals calcium, barium, or strontium which does not form part of the photoelectric electrode ; the alkaline earth metal removes hydrogen or other gas formed by the action of alkali metal on glass. As shown, a piece of calcium is placed in a heating coil 13 mounted below and connected at one end with a tinned screen 9 which prevents the deposition of silver and alkali metal on the lower part of the wall, and removes excess alkali metal. The screen is insulated by a tube 10 from one end of the anode 6. After evacuation, silver applied to the anode is vaporized to form a deposit on the wall. Oxygen is admitted and a discharge passed to form silver oxide. A small quantity of calcium is vaporized to clean up gas and form a deposit 15 on the wall. Calcium is introduced, the cell sealed off, and the calcium heated again to deposit a further layer. The cell is heated to form a layer consisting of a mixture of calcium oxide, silver and calcium with a thin adsorbed layer of calcium. Hydrogen or other gas is removed by the calcium layer, and a further quantity of calcium may be vaporized. Excess calcium combines with tin on the screen. In a modification, a mixture or an alloy of calcium and tin is contained in a capsule mounted on a wire on the foot, the upper part of the capsule forming a screen. The capsule is heated by induced current and a layer of calcium and tin is formed on the lower part of the wall. In other arrangements calcium is obtained by heating a mixture of calcium oxide and zirconium or thorium, and tin from a mixture of tin oxide and zirconium ; or calcium and tin are obtained from calcium stannate. Carbon or lead glass may be used for removing excess calcium. Specification 396,348 is referred to.

Abstract: 1447437 Continuous casing SCHLOEMANNSIEMAG AG 7 June 1974 [9 June 1973] 25504/74 Heading B3F A continuous casting mould 9 is carried by a carrier 2, journalled by trunnions 3 on a support frame 1, so that it can be swung up (by an hydraulic device 5) about the axis of 3 to carry the mould 9 out of casting position as indicated in chain lines (it bears a spherical abutment 6 normally resting a plate 7 where it is located by a pin 8) there being also an oscillatory drive 16 on the frame 1 from which a push rod 15 extends to a pivot P on an oscillating lever 12 mounted by a pivot fulcrum 13 on the carrier 2 and connected to the mould 9 to reciprocate it; the position of the pivot P in relation to the axis 3 is such that the mould can be stopped at a selected position within its reciprocation stroke so that when the mould carrier 2 is swung up, any displacement of the mould 9, relative to the carrier due to displacement of the lever 12 because of the swing, is within the stroke of the mould. The arrangement, Fig. 4 (not shown), may be such that, during the throw of the pivot P with oscillation, it passes through the axis of the carrier trunnions 3 so that the drive 16 can be stopped when the pivot is coaxial with the axis and consequently there should be no movement of the mould 9 relative to the carrier 2. In Fig. 1 the pivot P is between the axis 3 and the fulcrum pivot 13 of the oscillating lever 12 so that the throw of the pivot is above the axis. In Fig. 3, the axis 3 is between the pivot P 1  and the fulcrum 13, and when P 1  is at its bottom dead centre as shown and the carrier 2 is swung up, it moves to P 1 <SP>1</SP> and the mould 9 correspondingly moves through a distance α relative to the carrier and back again.

Filed: 1950-10-20
Abstract: Flexible bags are made from a plasticized copolymer containing from 90 to 92 per cent by weight of vinylidene chloride and from 10 to 8 per cent of acrylonitrile, by extruding the polymer into a tube which is super-cooled, then extended longitudinally and radially to align the submicroscopic crystallites parallel to the film surface, and finally sealed at one end, e.g. by flattening and heating under moderate pressure.  The bags may be made with pockets or other special shapes by welding the flattened tube along the desired contour lines.  In use, a bag slightly larger than the article to be protected is employed and the bag shrunk on to the article.  In an example a copolymer comprising 90.6 per cent vinylidene chloride and 9.4 per cent acrylonitrile was prepared by polymerizing a mixture of vinylidene chloride monomer and acrylonitrile in water in the presence of the sodium salt of the dihexyl ester of sulphosuccinic acid and as catalyst hydrogen peroxide and sufficient ferric nitrate to provide 14 parts of iron per million parts of the mixed monomers. The mixture was emulsified and was held at 45 DEG  C. for 22 hours, at which time polymerization was 80 per cent complete.  The copolymer was coagulated from its latex, washed, dried, plasticized with 10 per cent of its weight of dibutyl sebacate, stabilized with 2.0 per cent of tetrasodium pyrophosphate, and then extruded into tubes. Specification 518,470, [Group VI], is referred to.

Title: Improvements in or relating to the manufacture of printed electric circuits
IPC: H05K3/04
Filed: 1956-08-22
Abstract: A method of making a printed circuit panel from a non-conducting sheet having on one surface a conducting layer comprises placing the non-conducting side of the sheet on the face of a die formed with indentations corresponding to the required conducting strips or areas in the circuit panel, causing the sheet to be deformed into intimate contact with the indented die surface and machining the conducting layer from those parts of the sheet which were not forced into the indentations.  When the indented die has been made (see Group XXII) a plaster cast of the die is formed and used for the production of working dies in type metal or in a resin.  A sheet of polyvinyl chloride is clamped across a mould 5, Fig. 2, the assembly warmed to make the sheet plastic and air is then evacuated from the outlet 8 so that the sheet is sucked into close contact with the mould and allowed to set.  A sheet of copper foil 14 is fixed by adhesive to the bottom of the plastic-tray 12 thus produced and the latter is inverted and clamped, as shown in Fig. 4, on an indented die 16 extending across a vessel 18.  Holes 15 are drilled through the die so that the indentations are in communication with the vessel.  The plastic sheet is again warmed and the vessel evacuated from the outlet 20 so that the sheet with the foil attached is sucked into the indentations and allowed to set in that shape.  The copper foil is machined from the top face of the sheet, leaving that in the indentations which is then given a solder coating 27 by dipping, Fig. 5.
