Title: Improvements in leached foam type electrodes and methods for their manufacture
IPC: H01M4/86
Filed: 1968-06-28
Abstract: 1,221,543. Porous gas electrodes. GENERAL ELECTRIC CO. 28 June, 1968 [30 June, 1967], No. 31057/68. Heading H1B. Gas electrodes comprise a fluid-permeable electrocatalytically active mass having an internal pore network having the same geometric configuration as the solid material of an open cellular foam, and a current collector in electrical contact therewith. The electrodes are formed by contacting an open cellular foam with a more noble current collector, filling at least the voids of the foam with the active mass and removing the material of the foam. The active mass may also contain particles of a leachable substance to produce secondary pores, and a layer of a gas-permeable hydrophobic polymer may be applied to one surface of the electrode. The current collector may be a screen, expanded metal, foam or felt of Ti, Ta, Pt, An or Ag or their alloys. The open foam may be of metal, e.g. Ni, Fe, Co, Zn, Cu, Ag, Al, Mg or their alloys, and be removed by leaching with an acid, e.g. HNO 3 , or it may be of an organic polymer which may be removed chemically or by burning out or vaporization, e.g. during the sintering of the active mass. The active mass preferably comprises a perfluorinated polymer binder and an electrocatalyst, e.g. Pt or a spinal with or without an additional electrical conductor, e.g. C or B 4 C, whilst the leachable particles therein may be of e.g. calcim metasilicate or SiO 2 . The active mass is applied to the foam in the form of a paste. Examples describe making of electrodes by pressing a Pt-screen into an Ni-foam, pasting the composite with a Pt-PTFE composition optionally containing particles of SiO 2  or calcium metasilicate, leaching the foam with HNO 3 , the SiO 2  with aq. NaOH, and the metasilicate in an aq. HNO 3  + HF and optionally applying a PTFE film to one surface. In another example the foam of an Ni-foam, Ptscreen composite is platinized and the composite is pasted with an aq. mixture of B 4 C 3  and PTFE. After drying and sintering the Ni-foam is leached out with aq. HNO 3  and a PTFE film is sprayed on to the surface of the leached foam side. The electrodes can be used in fuel cells with aqueous or ion-exchange membrane electrolytes as either anode or cathode and as cathodes in metal-air cells.

Abstract: 634,753. Switch handles ; switch cases BLOIS, W. H., and MARKS, A. E. Nov. 25, 1947, No. 31160. [Class 38 (v)] An isolating switch which interrupts the supply to an electrical apparatus when the cover of the apparatus is removed, has attached to the cover a switch-operating member in the form of a plug having pins which move the actuating member of the switch on the apparatus. The actuating member is a block 12, which rests on a base plate 11 and is biassed into the position shown by a spring 14 fixed between a post 13 on the block 12 and a post 16 fixed on the base 11. When the cover of the apparatus is replaced the pins 3, 4 of the plug enter holes 7, 8 in the switch casing. The pin 4, which is hollow and is longer than pin 3, engages an inclined surface 23 of the block 12 so moving the block to the right from the position shown. The end of the post 16 is now exposed in a hole 18 in the block and on the continued insertion of the pin 4, it engages the end of the post 16 and forms a pivot about which the block 12 can rotate. The conical end of the plug pin 3 having entered the hole 7 now engages an inclined surface 24, so that the pin 3 now causes the block to rotate to close and hold a " micro " switch 20. When the cover of the apparatus is removed the spring 14 returns the block to its original position and the switch is opened. For maintenance purposes, a coin 26 may be inserted in a slot 25 where it engages an inclined surface 27 and causes the block to pivot about the end of the post 16 to close the switch 20. Should the coin be left in the slot when the apparatus cover is replaced a pin 28 ejects the coin as the block moves to the right.

Title: Improved wool scouring process
IPC: D06L1/22
Filed: 1966-07-12
Abstract: Wool is scoured by washing it with water to remove suint and then passing it through a series of stages in which it is washed with an organic solvent or mixture of organic solvents in which wool wax is soluble, which is miscible with water and has a boiling point or boiling point range below the boiling point of water, the solvent passing from one stage to another countercurrent to the wool and the solvent from at least one of the stages being treated where necessary to remove substantially all the wool wax dissolved therein before being fed to the next stage.  The solvent may be acetone, isopropyl alcohol, a mixture of ethyl alcohol, ethyl acetate and acetone or a mixture of ethyl alcohol, ethyl acetate and isopropyl ether.  The treatment of the solvent to remove the wool wax may be carried out between the solvent stage in which the wool wax remains completely in solution and the immediately preceding stage to which the addition of the solvent flowing rearwardly from the stage ahead causes separation of the wool wax in the immediately preceding stage when operated at or about the same temperature, for example between the third and second stages or second and first stages in a four stage solvent washing section.  The water washing and solvent washing stages preceding the treatment of the solvent to remove the wool wax dissolved therein may be carried out at or below ambient temperature and the latter stages of solvent washing carried out at a temperature of from 45 DEG C to the boiling point of the solvent. The wool wax may be removed from the solvent by filtering or centrifuging to remove dirt and solid particles, cooling the liquid to a temperature between 0 DEG C and -50 DEG C, and separating the precipitated wool wax from the solvent by settling, centrifuging or filtration.  The washing with water may be effected by passing the wool through a cold water bath or by spraying the wool with cold water and removing excess water by squeezing or the washing may comprise two or more such washes with cold water moving from one bath to another in countercurrent to the passage of the wool. The wool may be passed through the solvent washing section positioned between two carrier bands of nylon mesh or woven wire mesh, the solvent washing section comprising a series of vessels filled with solvents and squeezing means to remove excess solvent from the wool before it passes to the next bath, the excess solvent flowing back into the vessel from which the wool has been withdrawn, and solvent passing from one stage to the preceding stage being allowed to flow over or being sprayed over the wool as it leaves the preceding stage and before excess liquor is removed from the wool.  In the latter solvent stages the wool may be agitated by mechanical, sonic or ultrasonic vibrations or by pulsation of the liquid.  The scoured wool may be dried in a drier working under a closed nitrogen system at 60 DEG -70 DEG C.
