Title: Manufacture of shaped articles such as filaments of aromatic polysulphonamides
Inventor: MARSDEN RALPH JOHN BASIL
IPC: D01F6/76
Filed: 1957-11-25
Abstract: A solution containing both para- and meta-substituted aromatic polysulphonamides is spun into an aqueous coagulating bath to form filaments, the solvent of the solution being miscible with the bath liquid in all proportions.  The polymers are made from the meta- and para-substituted aromatic disulphonic acids and diamines such as hexa-methylenediamine.  The spinning solution preferably contains not more than 5% by weight of the meta-substituted polysulphonamide, based on the total weight of the polysulphonamides in the solution. The spinning solution solvent may be an aqueous solution of a base such as caustic soda, dimethyl formamide or ethylene carbonate.  In an example, a 25% solution of polyhexamethylene benzene metadisulphonamide and the corresponding para-compound in the relative proportions of 5 : 95 dissolved in an aqueous solution of 200 grams of caustic soda per litre is extruded into an aqueous coagulating bath containing 164 grams per litre of sodium acetate in a 4,5% solution of acetic acid at about 64 DEG C.  Specifications 875,067, 875,069, 875,070 and 875,071 are referred to.

Title: Hydraulic valve
IPC: F16K1/12
Filed: 1962-10-01
Abstract: 976,657. Valves. FMC CORPORATION. Oct. 1, 1962 [Oct. 18, 1961], No. 37030/62. Heading F2V. A valve comprises a housing 12, Fig. 1, having an inlet 14 and an outlet 16. A valve assembly 30 is mounted in the housing and comprises a cylindrical body 32 forming a chamber 44 which is in communication with the inlet through passages 40, 42 controlled by a throttle valve 48. A piston member 57 is slidable in the chamber and carries a seating ring 62 which co-operates with a valve seat 86, surrounding the outlet. The seating ring also forms a seat for a pressurerelieving valve member 81 which is loaded by a spring 82 and controls a bleed port 98 leading to the outlet by ports 100. The stem 78 of the valve 81 carries a collar 106 and a slot 110 which receives an actuating lever 114. To open the valve, the lever is actuated to open the pressure-relieving valve to allow escape of fluid from the chamber 44 and the collar 106 then abuts a cap 64 of the piston and the lever then opens the main valve. When the lever is released, the pressure-relieving valve closes and the flow of fluid through the restricted passage 40, 42 allows slow closing of the main valve. The valve may be closed quickly by hand, by rotating the lever to engage a pin 124, such movement of the piston 57 creates a suction effect in the chamber 44 and the valve must be held closed until the chamber is filled through the restricted passage. The cap member 64, Fig. 5, is formed with three equally spaced concave surfaces 104 separated by cavities 102. The cavities have holes 68 for attaching the cap by bolts to the piston member 57 and ports 100 leading from the bleed port 98. When the valve is being opened, flow past the surfaces 104 creates a suction effect in the cavities 102 which assists the bleed from the chamber 44. When the valve is closing, the flow past the valve seat is changed in direction by the concavities 104 and the reaction forces act against the valve closure movement to prevent chatter and the valve slamming to the closed position. The surfaces 104 may be formed as surface of a cylinder having a radius equal to that of the piston 57 and axis tangential to the piston 57.

Title: Donning device and bobbin handling means therefor
IPC: B65H67/06
Filed: 1965-09-01
Abstract: 1,111,907. Donning and doffing apparatus. WILLCOX & GIBBS. 1 Sept.. 1965 [2 April, 1965], No. 37272/65. Headings DID and D1F. A donning and doffing carriage which can travel along a row of spinning spindles, has a supply of bobbins, of which the tip and butt ends are of different diameters, arranged in random fashion, and means are provided to segregate the bobbins according to the diameters of the ends facing in one direction, and orienting the bobbins so segregated that they are delivered to a receiver with all the foremost ends being of the same diameter. The carriage and donning device are generally of the kind described in Specification 1064466 and the doffing device is of the kind described in Specification 965,166. The supply comprises a hopper Fig. 5 from which the bobbins in random arrangement are fed into a shoot 42 and prevented from jamming by rotating paddle wheels 43, 44, 45. They are picked up one at a time from the shoot by a rotating paddle-wheel 51 in the lowermost pocket of which the bobbins are acted upon by cam-surfaces at each end of the wheel, so that lying horizontally, they are shifted in the direction of the tip-end. Accordingly all. the bobbins with the tips facing one way are displaced relatively to those with the tips facing the other way. The bobbins thus segregated are raised to an orienting member 65 in vertical guides 55 by pairs of toothed racks 62, 63 alternately projected into the path of the bobbins by rotating eccentrics as described in Specification 1064466. The member 65 comprises a hub fixed on a rotating shaft 66 Fig. 8, parallel to the direction in which the bobbins lie. On the hub are heads mounted to rock independently of one another about an axis at right angles to the shaft 66 against the tension of springs connecting the heads to the hub. Each head has fingers 82 adapted to pick up one bobbin at a time from the top of the guides 55 as the hub rotates. The bobbins, projecting some to the right and some to the left, encounter one or other of two pads 85 which retard the bobbins at one end causing them to tilt and rotate the heads one way or the other according to which pad is engaged. As a head rotates. pins 86 thereon are made to engage fixed pins 87 causing the head to rotate still further and turn the bobbin through 90. With continued rotation of the head, the butt end of the bobbin is engaged by a stripper bar at the top of a supply shoot whereby the bobbin is released to be moved to the vertical by a yoke 90. As the bobbin is turned through 90, the head is latched against return, the latch being released when it engages a fixed cam after the bobbin is released. The drive for the device may be derived from the railengaging wheels of the carriage, from a starwheel engaging successive spindles as the carriage moves, or from a motor supplying a torque-amplifier controlled by the star wheel. The latter is mounted by a clutch preventing strain on the spindles, and allowing the carriage to move backward freely.

Abstract: 1,028,200. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. Sept. 25, 1963, No. 37713/63. Heading H1K. A semi-conductor device is made by providing a protective layer on a plane face of a low resistivity N(P) type semi-conductor body, diffusing an acceptor (donor) impurity into the wafer through a hole in the layer to give a surface acceptor concentration fully compensating the donor concentration, and producing a zone of P(N) type in the high resistivity zone thus produced by a further diffusion step. Typically, in forming a diode, boron is diffused into an N+ silicon wafer through an aperture formed by a photolithographic process in a protective silicon oxide layer to produce a compensated N zone. Boron at a higher concentration is then diffused through a smaller aperture to produce a P zone. Contacts are then made to opposite sides of the PN junction, preferably through holes in the oxide. To form a transistor, a further N zone is formed within the P zone by diffusion and appropriate contacts made to the three zones. Similar processes may be effected on germanium bodies.
