Title: Improvements in or relating to the manufacture of artificial filaments
IPC: D01D5/06
Filed: 1943-05-26
Abstract: In the production of artificial filaments by the extrusion of viscous solutions of colloidal material in aqueous media of alkaline or acid reaction through metal spinnerets into coagulating baths comprising aqueous solutions of electrolytes of acid or alkaline reaction respectively, the tendency of the orifices of the spinneret to clog is reduced by passing an electrolytic electric current through the coagulating bath, in such a direction that the spinneret is the cathode or the anode according as to whether the viscous spinning solution is alkaline or acid respectively.  The process is applicable to the spinning of viscous solutions of protein, e.g. casein or denatured vegetable globulins into an aqueous acidified saline solution, but it is also applicable to the extrusion of viscose, alkali - soluble cellulose ether solutions, or solutions of partially de-acetylated chitin in dilute acetic acid.  The voltage of the current is such as to cause a slight evolution of hydrogen at one of the electrodes.  The direction of the current is such that the zone of coagulation is removed from the spinneret, and any tendency of the zone to shift towards the spinneret is counteracted by increasing the voltage applied.  In an example, a solution of peanut globulin in sodium hydroxide is extruded into an aqueous coagulating bath containing sulphuric acid, sodium sulphate and sodium chloride, at 30 DEG  C., and through which an electric current is passed, the spinneret being the cathode and the metal bath the anode.  The filaments are withdrawn, treated in an extended state with a saturated brine solution, and finally treated with an insolubilising solution.  In the Provisional Specification it is stated that the process is applicable to the extrusion of cuprammonium-cellulose solutions.

Plug couplings and connectors.-A contact for a plug and socket type switch has two groups of at least two contacts all electrically connected together, the groups being resiliently urged in different directions normal to the contact surfaces, and the groups are located one within the other to engage the inner and outer surfaces of the co-operating contact. The socket comprises four pairs of plates 1 - - 4 to each of which is riveted a pair of studs 5 surrounded by compression springs and passing through apertures in a housing 6, the apertures being large enough to allow of a limited amount of selfadjustment. Each plate consists of a U-shaped copper sheet, between the arms of which is riveted, as by the studs 5, a strip 9 of copper braid extending in the form of a flexible pig-tail to a common terminal 8. The pig-tails are bent to conform to the, preferably cylindrical, periphery of the member 8 to which they are bound by wires 11 and sweated if desired, an external clamping ring 12 being added. The co-operating plug 13 is a hollow square section member and four more plates 14 and rivets 15 are provided to engage its inner surface. The parts of the plug and socket which first meet on closure are wedge-shaped or rounded off. The housing 6 is bolted to a flange 10 on the member 8, and the flange is secured by bolts 18 to a cylindrical conductor 19 surrounded by an insulator 20, which is cemented in a flange tube 22 secured to the casing 23 of the movable part of a drawout type switchgear.

In a rectifier having intermediate electrodes between the cathode and anode kept at progressively increasing potentials, the portion of the envelope surrounding these electrodes is formed of a pile of elements sealed together by material 2<SP>1</SP> softenable above 350‹ C. Such material may be a glass flux or silver metal or alloy. The rectifier may consist of a metal condensation chamber, Fig. 1 (not shown), housing the mercury cathode and supporting insulating envelope elements sealed end-to-end and carrying ring electrodes connected through leading- in wires to tappings on a potentiometer. The ring electrode nearest the cathode is connected to an impulse generator to form the control grid. End flanges on the elements may be sealed together to form annular recesses to increase surface resistance to breakdown voltages; alternatively a number of recesses or bosses may be provided around each element and may be provided with metal caps or internal discs, Fig. 5 (not shown), to support the leading-in wires. An annular recess may have an annular band supporting the electrode through a spider. Similarly, the elements may be provided with external fins. Tapered glass elements 41, Fig. 4, may be sealed together at shoulders 42 and be extended to form skirts 43 each having a beaded edge 44 and carrying an electrode through a spring ring 45. The leading-in bosses 47 are arranged in staggered formation. The lowest element may be sealed to a metal flange on the condensation chamber by a glass flux; alternatively the sharp edge of a steel ring may be forced into the chamfered lower edge of a glass element or a cylindrical groove in the edge of the chamber may embrace the thickened end of the element. The tube may have an oxide cathode adjacent which is arranged a mercury pocket in the envelope. Flanged ceramic elements 2, Fig. 9, carry the insulating mercury cathode container 6 housing the ignitron 92, spot fixing element 90 and exciter anode 93. An oil or water cooling system 90A is provided. A dome-shaped insulating element 94 carries a graphite anode 8 having an electrical heater 95; and the nearest auxiliary electrode 2 is provided with an extension 96 surrounding the anode. Air from a blower 99 is forced through the jacket 97 and heated by an element 101 so that the temperature gradient is 250-450‹ C. at the top to 20‹ C. at the bottom. Both heaters may be fed from the transformer 102. Gas diffuses to the cold lower end where it is bound by a getter and continuous pumping of the rectifier is eliminated. The ring-shaped electrodes may be provided with inclined strips or helical plates to check the axial movement of charged particles. Specifications 442,092 and 488,209 are referred to.

[Class 83 (iv)] In upsetting machines of the type having two electrodes in the form of an anvil and vice between which the work is electrically heated and upset by pressing it against the anvil, means is provided for simultaneously controlling the fluid pressure in the cylinder of the upsetting ram and the anvil supporting ram. As shows, a vice B, Fig. 1, supports the work a, but allows of it sliding through. Oil under pressure in a cylinder C operates a ram C pressing the work against the anvil. A ram F carries an anvil D. The ram C carries two cam plates, one g of which is shown. The plate g when moved causes a horizontally disposed lever H to rock and vary the pressure of a pad j, Fig. 3, spring j<3>, and pad j4, acting on a ball valve K. Thereby the pressure behind the ram F is varied in accordance with the shaping of the plate g. The second cam plate in similar manner rocks a second horizontally disposed lever to vary the pressure on a ball valve in the housing of a pump casing leading by a pipe m<2> to a cock R. A hand lever 2 operating the cock R may be coupled to a hand lever controlling a cock Q connected by a pipe q<1> to a ram cylinder f containing the ram F. The cock Q is also connected by a pipe n to a pump J driven from a motor U and by a pipe q<2> to a tank P. The cock R is connected by a pipe r<4> to the vice B by a pipe r<3> to the back of the ram cylinder c and by a pipe r<1> to the tank P. A pipe k<3> connects the tank P to the pump J.
