Title: Improvements in or relating to circular knitting machines
IPC: D04B15/88
Filed: 1941-10-20
Abstract: 551,287. Knitting machines. ME L LOR, BROMLEY & CO., Ltd., BROMLEY, T. C., and SHORTLAND, A. Oct. 20, 1941, No. 13484. [Class 74 (ii)] For tensioning fabric having pouches knitted upon a circular machine, fabric-engaging members 12 are pivotally or slidably mounted upon a device movable axially of the needle cylinder or cylinders so that during the formation or after the completion of a pouch the operative ends 12b of the members conform to the path followed by the fabric as it leaves the needles. The members 12 may be arranged radially around the axis of the machine, or a single fabric engaging member or a group of such members is directed towards the group of needles knitting the pouch. In one form, Fig. 1, as applied to a double-cylinder machine having inside sinkers, the members 12 are pivotally mounted in tricks 13a in a carrier 13 secured to the end of a rod 16 movable axially under control of the machine timing mechanism, and are held by a spring ring 20 against a tricked cam block 17 so that as the rod is lowered, the ends 12b of the members 12 are swung inwardly to conform to the surface of the sinker cup 6 over which the fabric passes. In another form, a tensioning member is slidably mounted in a disc and is slotted to receive a cam projecting from the underside of the usual adjustable verge arranged at the lower end of the rib cylinder. In operation, as the disc is lowered and raised by the control rod, the slidable tensioning member is moved radially by the cam member. In a modification the slidable member 12 is arranged between discs 30, 31 embracing a pinion 37 secured to a screwed sleeve 38 engaging a nut 39 secured to the bottom of the control rod 27. The discs 30, 31 are held against rotation by a rod 35, so that upon the member 12 engaging the fabric furthering lowering of the rod 27 causes the sleeve 38 and pinion 37 to rotate. The pinion engages a toothed rack upon the member 12. In the upward movement, the pinion 37 engages a stop 36, and upon continued movement of the rod 27, the member 12 is moved radially outwards to its inoperative position.

Title: Storage and supply of electrical energy by an electro-chemical process
IPC: H01M8/00
Filed: 1920-05-17
Abstract: 143,532. Habicht, F. P. May 17, 1919, [Convention date]. Electrodes; electrolytes.-The oxidizable electrode of a battery consists of an alkali metal or alloy thereof which is supplied in liquid form to the battery during its operation. The resulting compounds are continuously withdrawn, the alkali metal being recovered electrolytically for reuse in the battery. Fig. 1 shows a cell employing fused sodium 36 as one electrode in an electrolyte of fused caustic soda. The other electrode 4 consists of a metal such as iron or silver in the form of filings &c. through which air and water vapour are blown through a pipe 5. Channels 6 are provided to carry off the air and water vapour and prevent their access to the melted sodium. A diaphragm of magnesia may be interposed between the electrodes for the same purpose. The air supplied may be previously heated by the issuing air. Caustic soda formed in the cell is withdrawn through a pipe 7 and subsequently treated electrolytically for the recovery of sodium to be used again as the negative electrode. Various constructions are described for preventing the air and water vapour from having access to the melted sodium. For this purpose the sodium may be contained in inverted troughs within the cell, the other electrode and air supply pipes being above or to one side of the troughs. The positive electrode may be surrounded by a mixture of fused caustic soda and manganese dioxide, which when reduced may be re-oxidized to manganate by blowing air into the fused mass. Instead of sodium and caustic soda other alkali metals and their hydroxides may be used. In another construction, sodium is injected in fine sprays through a layer of molten lead or tin at the bottom of the cell, an electrode of silver being supported in the upper part of the cell. The Specification as open to inspection under Sect. 91 (3) (a) describes a cell in which two corrosion-resisting electrodes are placed in a cell divided into compartments by a diaphragm and through which a fluid passes which is capable of being reduced and oxidized. Solutions of salts of cerium, chromium, iron, or manganese at high temperatures may be used. This subject-matter does not appear in the Specification as accepted.

Abstract: 792,588. Centrifugal separators. RESEARCH-COTTRELL. Inc. May 3, 1956 [July 29, 1955], No. 13695/56. Class 23 [Also in Group XL(a)] In a combined electrostatic and mechanical gas cleaning apparatus, tubular collecting electrodes 24, which are supported in a header plate 22, are positioned vertically above separator tubes 44 supported in a header plate 42. Discharge electrodes 38, having disc-like members which provide a plurality of corona discharge edges, depend from a high tension frame 30. Gas containing suspended particulate material enters the apparatus through the inlet 16 and is then mixed with water particles from spray nozzles 62. The gas and entrained water passes between the lower, narrower portions of the collecting electrodes and the inner surfaces of the separator tubes where it is given a vortical motion by means such as vanes or tangential inlets. The gas is subjected to centrifugal separation within the tubes 44 and a portion of the particulate material leaves the tubes through narrow outlets communicating with hopper means at the lower end of the apparatus. The gas stream then passes up through the collecting electrodes where corona discharge and the high voltage maintained between the discharge electrodes and the collecting electrodes separates the remainder of the material suspended in the gas stream which is precipitated upon the inner surfaces of the collecting electrodes. Flushing liquid from the ponds maintained by conduit means 28 above the plate 22 flushes the precipitated material from the inner surfaces of the collecting electrodes down through the outlets of the separator tubes 44.

Title: Improvements in or relating to a self-supporting aerial
IPC: H01Q1/40
Filed: 1956-05-04
Abstract: 801,200. Aerials. COLUMBIA PRODUCTS CO. May 4, 1956 [July 14, 1955], No. 13946/56. Class 40 (7). A resonant aerial suitable for use on a motor vehicle comprises a conductive core embedded in an insulating rod comprising glass fibres and a bonding agent therefor. The aerial is made flexible and resilient and is capable of withstanding considerable impact shocks. Moreover, as the ratio of glass fibres to bonding agent is made high the conductor coating has a high dielectric constant and the aerial length for a given operating frequency is less than that of a simple resonant conductor not encased in dielectric. Preferably the conductor 11 is first surrounded by a plurality of longitudinally extending glass fibres 10a acting as tension members and the whole then spirally wound with further glass fibres 10b forming an impact resisting layer. All the fibres are coated with a suitable bonding agent, for example a resin of the polyester type, and the assembly may be wound with tape to retain the desired arrangement during curing of the resin. In order to make the dielectric constant of the insulating material high, it should consist of approximately 70 per cent fibre glass and 30 per cent bonding agent by weight. In order to raise the dielectric constant of the material further the bonding agent may comprise resin loaded with materials such as titanium dioxide or barium titanate. The conductive core 11 may be attached to a metal socket at one end of the aerial and may comprise solid or stranded wire or a group of spaced wires where a broad bandwidth is desired. The lengths of the longitudinally extending glass fibres may be graded to give the tapered shape shown and the free end of the aerial may terminate in a ball.
