Title: Improvements in or relating to methods of spinning fine fibres and like structures
IPC: D01F6/18
Filed: 1953-06-01
Abstract: In the wet spinning of aqueous salt solutions of polymers containing 85 per cent or more of acrylonitrile, from 2 to 30 per cent by weight of an organic peptizing agent (i.e. an organic compound capable of dissolving or swelling the polymers) is introduced into the spun product either by dissolving from 2 to 30 per cent of the agent, based on the weight of polymer, in the spinning solution, or by passing the freshly spun product through an aqueous bath containing from 5 to 30 per cent of the agent until the spun product has absorbed from 2 to 30 per cent of the agent.  Peptizing agents specified are dimethylformamide, 2 - (N - hydroxyethyl N - methylformamide), dimethyl cyanamide, acetonitrile, succinonitrile, nitromethane, nitroethane, 2-nitropropane, unsymmetrical diethylurea, dichloroformal, di-(2-chloroethyl) formal, dimethyl sulphone, tetramethylene cyclic sulphone, 1,4-dioxane, butyrolactone, gamma - phenylvalerolactone, gamma - caprolactone, phenylpyrollidone, oxindole, acetoxindole, para - toluenesulphonamide, phenol, thymol, 4,41 - dihydroxy diphenylmethane, and tertiary butyl phenol.  The peptizing agent may be incorporated in the polymer by polymerizing acrylonitrile in an aqueous salt solution containing the agent which serves to lower the molecular weight of the polymer produced, and also, in the case of phenols, accelerate the polymerization. Alternatively the polymer particles may be swelled by contact with the agent and then dissolved in the aqueous salt solution, or the agent may be added directly to the polymer solution.  When the peptizing agent is applied to the polymer after spinning the agent may be present in the initial coagulating bath or in any subsequent washing bath.  The aqueous salt solutions used may comprise both a solvent salt such as zinc chloride and a non-solvent salt such as calcium chloride.

Title: Improvements in and relating to electric welding apparatus
IPC: B23K11/24
Filed: 1936-06-02
Abstract: 459,346. Supply systems for resistance welding. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. June 2, 1936, No. 15403. Convention date, June 1, 1935. [Class 38 (iv)] In A.C. spot or seam welding in which a part of one or more cycles is utilized for each timed weld, and in which rectifiers controlled by phase variable A.C. grid potential are blocked to terminate the weld when a timing or control condenser is sufficiently charged, the condenser is charged by impulses produced in dependence upon the phase .variable grid potential applied to the rectifiers. The primary of the welding transformer 2 is supplied from the mains 1 through opposed rectifiers 4, 5 in parallel, the follower valve 5 being controlled in dependence upon the pilot valve 4. The control potential for the grids of the rectifiers is taken from the mains 1 through a phase shifter 6 and transformer 9. The secondary winding 10<1> in the circuit of the control grid of the pilot valve 4 is short-circuited between welds by the auxiliary valve 11, the grid of which is connected to the positive pole of the battery 14 through resistances. When the control switch 12 is actuated to connect contacts a, b, current from the battery charges the adjustable control condenser C and the potential on the grid of the valve 11 drops so that a positive grid potential from the transformer 9 ignites the pilot valve 4. This potential simultaneously is applied to the grid of the valve 7, to complete a circuit through the primary of control transformer 15 in parallel with the primary 10 of the grid transformer 9. The secondary 16<1> of the control transformer thereby applies through the rectifier 17 an impulse dependent upon the main grid potential to complete the charging of the control condenser C. When the condenser is sufficiently charged, the potential applied by the battery 14 to the grid of the auxiliary valve 11 renders it conducting, thus short-circuiting secondary 101 and blocking the pivot valve 4. Secondary 16<11> of control transformer 15 charges condenser 22 which is associated with resistance 23 and rectifier 24 so as to co-operate with secondary 10<11> of grid transformer 9 to start and stop follower valve 5 to deal with the negative part of each cycle in dependence upon pilot valve 4. Valve 5 may be cut out by switch 21. By operating switch 13, valve 11 may be cut out, the ratios of current and pause for seam welding being then regulated by a rotating switch drum 25.

An electron source comprises within a vacuum-tight envelope 1, Fig. 5, a plasma source, e.g. an ultra-violet ray lamp 100 for ionizing caesium vapour evaporated from bath 12 by heating chamber 4, a coil 2 for applying an ariel magnetic field in the interaction space, the intensity of which is a periodic function of time, whereby the ions and electrons of the plasma are rotationally accelerated and radially separated, the peripheries of electrodes 5, 6 being used for capturing the ions and aerial apertures thereof for extracting the electrons in a beam. The magnetic coil 2 carries a sawtooth or sinusoidal current and the magnetic field is uniform though time varying. The chamber 4 which contains silicone oil at 200‹ C. may have its temperature varied to adjust the beam density. Grid 5 and accelerating anodes 6, 7 are slitted to prevent the flow of induced currents. Voltage pulses are applied to 5, 6, 7 at the end of each cycle of the magnetic field, sources 8, 9 being synchronized by devices 11 so that grid 5 goes negative and 6, 7 positive with respect to ground. An auxiliary coil 10 assists in forming the electron beam.

Patent GB-1161927-A (GB)
Title: Improvements in or relating to Fluid Pressure Valves
IPC: F16K17/194
Filed: 1967-04-04
Abstract: 1,161,927. Fluid-pressure servomotor systems. VAREC Inc. April 4, 1967, No. 15494/67. Heading G3P. [Also in Division F2] A valve, for automatically venting a storage vessel 11 when the pressure therein is either below or above atmospheric pressure, includes a twopart valve casing 10 secured to a pipe section 12 which is welded to the vessel 11, the upper part of the casing, which is in the form of a dome 18, carrying a pressure responsive pilot valve 34, and the lower part of the casing, formed as an open support from a series of spaced rib members 13E, being secured, together with a plate 13 having an upstanding cylindrical portion 13C, to the pipe section 12. The portion 13C constitutes a valve seat engageable by a valve closure member 20 which is carried by a diaphragm 17 secured between the two parts of the casing 10. A tapered pipe section 24 is secured to the closure member 20 and is telescopically received within a similar pipe section 32 secured to the pilot valve. In operation, upon the vessel pressure exceeding atmospheric pressure, a similar rise in pressure occurs in a chamber 26, defined by the dome 18 and diaphragm 17, and this pressure acts on the pilot valve closure member 40 tending to raise it from its seat. Upon this occurring, flow from the vessel 11 takes place through pipes 24, 32 and openings 44C to atmosphere, and flow from chamber 26 takes place through openings 38A and 44C to atmosphere, the first flow, on account of the tapered portions 24A and 32A of the pipes 24, 32, developing a velocity head which enhances exhaustion of chamber 26, serves to maintain member 40 unseated and so permits member 20 to become unseated. Upon the vessel pressure falling below atmospheric pressure, the pressure differential across the diaphragm becomes such that atmospheric pressure acting on the underside of the diaphragm raises member 20 from its seat so allowing the vessel pressure to be increased. Should the diaphragm become ruptured so preventing member 20 from unseating, then if the pressure built up in chamber 26 becomes sufficient to raise a disc like closure member 28 from its seat, on to which it is held by a magnet 30 or a spring (50, Fig. 2, not shown), a free transfer of pressure takes place through apertures 20C formed in the closure member 20.
