Title: Method and apparatus for manufacturing coiled sliding clasp fastener elements
IPC: B29D5/06
Filed: 1964-08-20
Abstract: 1,065,155. Moulding helical sliding-clasp fasteners. YOSHIDA KOGYO KABUSHIKI KAISHA. Aug. 20, 1964 [Nov. 13, 1963; Nov. 20, 1963], No. 34077/64. Heading B5A. A machine for making a substantially oval, generally helical stringer for a sliding-clasp fastener from a filament W of resinous thermoplastics material, comprises a rod 11 which extends between screws 13, 14 of substantially the same pitch, a relatively short rod 12, and a vertically reciprocable clamp 8 which holds both rods. The clamp 8 derives its motion from a shaft (7), Fig. 3 (not shown), and the filament (W) is led from a bobbin (4) fixed to a rotatable table (1) and is initially coiled around rods 11, 12, Figs. 4, 5 adjacent the nose of clamp 8 which is stepped as at 9. The screws 13, 14 are displaced relative to one another, as shown, so that on raising clamp 8 the coiled filament C is initially fed upwardly by screw 13 only. The left-hand side of the coil is delayed on encountering screw 14, until picked up by thread end 17, the coil thereby assuming the configuration shown between the screws. The function of rod 12 is to allow a loop to be formed of sufficient diameter to permit this configuration without damage to the filament. If the crests 16, 17 of screws 13, 14 are in horizontal alignment as shown, the legs (47), (48), Figs. 1a lb (not shown), of each turn of the coil lie in the same plane, but the vertical positions of the screws may be adjusted by movement of blocks (28), (29), Fig. 2 (not shown), which hold upper, non-threaded, extensions of the screws. Heaters (26), (27), Fig. 3 (not shown), soften filament (W) to facilitate deformation and a punch (33) is provided to form interengageable heads (50), Fig. 1a (not shown), on each turn of the coil. The latter is cooled by air from a nozzle (44), Fig. 2 (not shown), and in the event of fouling, the filament (W) may be cut by a knife (43).

Title: Process for recovering dimethylnaphthalenes from cracked gas-oil by azeotropic distillation
Inventor: WYNKOOP RAYMOND
IPC: C10G21/00
Filed: 1963-08-30
Abstract: A dimethylnaphthalene concentrate containing 2,6- and 2,7-isomers is obtained from a cracked gas oil containing dimethylnaphthalenes and boiling within the range 400-650 DEG  F. by mixing with a polyalkylene glycol or a mixed ethylene glycol-propylene glycol ether and subjecting the mixture to azeotropic distillation and recovering dimethylnaphthalenes from the overhead.  The gas oil preferably boils in the range 480-515 DEG  F. and contains at least 40% aromatics. The glycol is preferably an aqueous diethylene glycol containing up to 20% by weight of water and is added in a ratio to hydrocarbon of 1-10 : 1.  The mixture is distilled to remove material boiling below 450 DEG  F. and from the bottoms is recovered, by further distillation, an overhead azeotrope boiling in the range 451-454 DEG F.  In cooling to below 100 DEG  F. the azeotrope separates into two phases; the glycol may be recycled and the dimethylnaphthalenes are recovered and separated by crystallization if desired.

Title: Improvements relating to the recovery of solvents
IPC: B01D53/04
Filed: 1932-12-09
Abstract: In the recovery by adsorption of solvents that are contaminated with corrosive substances such as sulphur chloride, the solventladen air or gas is treated to remove said impurities and their decomposition-products before it is passed through the adsorption apparatus.  For example the air either with or without a preliminary treatment with steam may be scrubbed with water or a weak alkaline solution to decompose the sulphur chloride and dissolve the resulting acids.  The invention finds particular application in the cold curing of rubber.

Abstract: 1,195,024. Injection moulding footwear. BRITISH UNITED SHOE MACHINERY CO. Ltd. 9 Aug., 1967 [10 Aug., 1966], No. 35727/66. Heading B5A. An injection moulding machine for moulding footwear has means for separating the mould members by a controlled amount (À015 to À045 inch) on completion of injection and prior to solidification of the injected material, thus enabling the moulded articles to be removed from the mould sooner than where the injection pressure is not relieved. A foot form 16 is moved to a lowered position to co-operate with a mould assembly 20 by means of an operating device 50 and toggle mechanism 52. Between the device 50 and the foot form 16 is a pressure relieving device 70 comprising a fluid pressure cylinder 79 having a piston-rod 78 connected by a link 83 to a pivoted cam member 72. On termination of injection a valve is actuated to retract the piston-rod 78 an amount controlled by a manually operated member 80. This causes movement of the point of engagement between the cam member 72 and the link 54, thus allowing upward movement of the cam member and thus of the foot form 16 due to pressure in the mould cavity.

Abstract: 937,789. Selective printing. MITE CORPORATION. Oct. 11, 1961 [Oct. 20, 1960], No. 36520/61. Class 100 (4). [Also in Group XL (b)] A teleprinter comprises a type cylinder, a first cable to move the cylinder axially on a shaft extending across the front end of the printer, a second cable to rotate the shaft, solenoids alternately oppositely directed and disposed longitudinally in the upper half of the printer for one of the cables and similarly arranged solenoids in the lower half of the printer for the other cable. The teleprinter described is of cylindrical shape, Fig. 1, of 3# inches diameter, for mounting in an aircraft dashboard. Typed tape emerges from a slit 24 and each character can be seen immediately it is typed through a window 26. Type selection.-An octagonal type-bearing prism 32, Fig. 11, can be rotated by solenoiddisplaceable pulleys 0, 1, 2 so that any one of its faces is parallel to the paper tape, the solenoids being so arranged that they produce displacements of , # and 1/16 respectively, and a similar pulley system (Fig. 12, not shown) is arranged to slide the type prism 32 to any one of eight positions along the shaft 34 on which the prism is splined. Fig. 3 (plan view) shows solenoids 100, 101, 102 which effect rotation of the type prism and Fig. 6 (bottom view) shows solenoids 103, 104, 105 which effect its lateral displacement. Paper tape and inking ribbon.-Paper tape 72 passes from a reel 70, Fig. 5 (side view), and Fig. 6, horizontally mounted at the rear of the printer, along a channel in the side of the printer and round a guide pivot to the front of the printer, Fig. 2, where it is frictionally gripped by drive wheels 92, 94 and rollers 98 before emerging from the slit 24. The inking ribbon comprises an endless tape 110, shown dotted in Figs. 5, 6 and 2, which passes over an inking felt 130, Fig. 6, and then along the length of the printer to drive-wheels 115, 117, Fig. 2, and rollers 132 so as to pass transversely across the paper tape. The paper tape and inking ribbon drive-wheels are geared together as shown and are advanced by a pawl and ratchet arrangement (Fig. 10, not shown) when the print hammer returns to its normal position after printing a character. The paper tape gripping rollers 98, Fig. 2, can be raised by depression of a button 30 to permit blank tape to be pulled from the printer. Printing hammer.-The type hammer, which comprises a sprung hammer head 91 mounted on a lever 114, Fig. 2A, is controlled by a solenoid 140, Figs. 3 and 5, which, by means of links 144 and 162, Fig. 3, causes a pin 170, Figs. 2, 2A and 3, to hit the hammer which, in turn, hits the inking ribbon on to the paper tape. Adjustable stops are provided to ensure that the pin 170 stops moving before the hammer hits the inking ribbon to ensure that a clean impression is made. Specifications 786,831 and 799,956 are referred to.
