Title: Improvements in electrochemical processes
IPC: H01M8/00
Filed: 1928-12-24
Abstract: 303,027. Citovich, E. Dec. 24, 1927, [Convention date]. Gas cells.-Electrolytic processes are carried out with an aqueous electrolyte at a temperature between 100‹ C. and the critical temperature. Under these conditions the processes are reversible and the products may be made to recombine with generation of electrical power. The process may be carried out in a high-pressure apparatus of the filter-press type the elements a of which are of a circular periphery. The end cells are supported rigidlv; the intermediate joints are rendered gas-tight by thermal expansion. The electrodes d are of fine copper or other gauze. Pipes c are provided for the introduction of electrolyte and reaction materials and for withdrawal of products. In an example, an alkaline solution is electrolyzed at 300‹ C. to produce hydrogen and oxygen which are collected in highpressure receivers initially filled. with steam at the cell-pressure the steam being gradually displaced. By slightly raising the temperature the steam-presure is raised so as to cause gas to reenter the electrode chambers; the reaction thereupon proceeds in the opposite direction and the apparatus functions as a galvanic battery. The anode may be in contact with carbon monoxide or other reducing gas or vapour or with an organic substance such as an oil which is oxidized bv the electrolytic action. A solid fuel in powdered form may be suspended in the anolyte and oxidized during electrolysis. A solid or liquid fuel may be heated with water and a catalyst such as a dissolved salt or copper turnings in an auxiliary high-pressure vessel to form a gaseous fuel which is then led to the anode. In another example air is led to the cathode; the oxygen is converted to water vapour and pure nitrogen remains. In the generation of oxygen an oxidizing electrode of ferric oxide or copper oxide may be employed. Precious metals, alloys, iron. nickel, oxides, sulphides, and graphite may be used as electrodes. Calcium chloride may be dissolved in the electrolyte to reduce the vapour pressure.

Abstract: 825,807. Mandrels for making wound tubes. PERMA TUBES Ltd. Dec. 13, 1957 [July 9, 1957], No. 38740/57. Class 99(2). A mandrel M on to which is wound helically paper strip impregnated with tar or asphalt comprises a number of slides S mounted for longitudinal reciprocating movement on a core 48, driving means for rotating the core and slides, and mechanism for causing one of the slides to move rapidly in a return direction while the remaining slides move slowly in the opposite direction. As shown, eight slides S are provided with arcuate outer surfaces 50 forming a cylindrical contour and longitudinally extending ribs 51 received in correspondingly shaped grooves 52 in the tubular core 48, the bore of the latter communicating by way of radial holes 55 with the grooves 52 and sliding surfaces 54 and 53 of the slides and core respectively. Each slide carries a radial arm 56 having secured thereto a pair of rods 57, 58 supporting a block 59 carrying a shaft 60 journalled on which is a cam roller 61 engaged in the cam track 64 of a cylindrical cam 63 keyed to a driving spindle 42. The cam track 64 has a "return" portion which in length is one-eighth the length of the track so that as the cam rotates seven slides are moved outwardly at a relatively slow rate of speed while a single slide is moved inwardly at a relatively high rate of speed. The rods 57, 58 are accommodated for reciprocating movement in a housing 68 which is rotated independently of the spindle 42. The mandrel is mounted in a casing provided with a reservoir for a hydraulic medium which is supplied to pumps coupled to an electric motor and driving hydraulic motors respectively coupled by chain reduction gearing to a drive sleeve secured to the housing 68, and by a chain to the spindle 42. A passage 106 supplies lubricant to the surfaces 53, 54, and a tube 88 carries a cooling fluid such as water to the ends of the mandrel to be projected onto the inner surface of a tube being formed ; another tube applies cooling water to the outer surface of the tube being made, and the water is collected in a sump to be returned to the cooling system. In operation, although the wound paper strip frictionally engages all the slides, the frictional engagement with the seven slides that move outwardly overcomes the frictional engagement with the single slide that moves inwardly resulting in outward longitudinal movement being imparted to the tube as the latter is formed on the mandrel. While the machine is in operation the helix angle of winding is adjusted by varying the differential between the driving speeds of the sleeve 35 and spindle 42, and the rate at which tubing is produced is varied by adjusting the speed of both the sleeve and the spindle.
