Title: Improvements in or relating to self-baking anodes for electric furnaces
IPC: C25C3/22
Filed: 1954-07-17
Abstract: 767,147. Electric furnaces with self-baking electrodes. KAISER CO., H. J. July 19, 1954 [July 20, 1953], No. 21033/54. Class 39(3) A self-baking anode in an electric furnace for melting ferro-alloys, producing calcium carbide or the electrolytic production of alumnium has a central hollow part forming a chamber 40 lying wholly below the unbaked surface of the anode, and furnace gases-including fluorine and carbon monoxide are withdrawn from the furnace through this chamber. The lower edge of the chamber 40 extending to just above the molten charge. The tar vapours at the top surface of the anode may be led away with the other furnace vapours and are burnt. In Fig. 1 in which inclined contact pins 29 supply current to the electrode in an anode casing 25, a hollow vane with side walls 45 open at the bottom 42 and converging at the top to form a thin upper edge 47 dividing the electrode mass is inserted in the anode mass parallel with the transverse sides of the anode casing 25 and extends wholly across the electrode. The walls 45 are connected by a rib 41 which rises as shown in Fig. 2 from a central low point to the sides of the electrode and guides the rising furnace gases through apertures 43 in the vane 45 into gas outlet pipes 44 in which the gases are burnt at 49 and detoxicated in pipes 50. The anode casing 25 is closed at the top by hinged flaps 27, and tar vapours from the top surface of the anode pass through apertures 48 into the outlet pipes 44. The inner ends of the inclined contact pins are nearer to the. walls 45 of the vane than to the electrode casing 25, whereby the lower electrode surface slopes upwardly towards the gas collection chamber. Vertical contact pins may be inserted from above into the anode paste instead of the inclined pins. Flexible connections 30 are made from the inclined pins 29 to a bus-bar 31 on each side of the electrode. The anode is supported from the lower contact pins 29 by suspension means 33 connected to jacking devices controlled by a wheel 34. Alumina is added to the furnace through bins 36. During operation of the furnace; the newly added croylite and alumina form a solidified crust between the bottom of the anode 24 and the vertical wall of the cavity 14 in the cathode 13 thereby forming an effective gas seal, so that furnace gases may be withdrawn by an exhaust blower through the electrode. Thin aluminium sheet may be used to obviate sticking between the anode mass and the walls of the casing or of the vane. Current is fed to the cathode by parallel rows of opposed contact rods 18 extending inwardly almost to the median line of the cathode.

Title: Improvements in and relating to the manufacture of antibacterial sulphanilamido compounds
IPC: A01N41/08
Filed: 1943-12-17
Abstract: Sulphanilamido compounds having antibacterial properties and of the general formula <FORM:0570196/IV/1> wherein X represents a benzene nucleus which carries a nitrile group in any one of the o-, m-or p-positions to the sulphonamide group, are prepared by interaction of an aminobenzene derivative carrying a nitrile group as a nuclear substituent in the o-, m- or p-position with (a) a benzenesulphonyl halide, advantageously in presence of an acid acceptor, such halide containing in the p-position a substituent readily convertible into an amino group, viz. an amino group protected by an acyl or other easily removable group or a nitro, nitroso, azo, hydrazo or other group capable of reduction to an amino group or a halogen atom, or (b) a benzenesulphonyl ester similarly substituted or substituted by an amino group in the p-position and subsequent conversion of the said convertible substituent, if present, into an amino group, e.g. by mild hydrolysis of an acylamino group, performed so as to leave the nitrile group unaffected.  In examples: (1) o-sulphanilamidobenzonitrile is obtained by slowly adding acetylsulphanilyl chloride to o-aminobenzonitrile, in pyridine, heating for 1 hour on the steam-bath, hydrolysing the precipitated N4-acetyl compound by boiling with hydrochloric acid and isolating the free o-sulphonamidobenzonitrile by neutralizing the solution; (2) m-sulphanilamidobenzonitrile; and (3) p-sulphanilamidobenzonitrile are similarly obtained from the m- and p-aminobenzonitriles respectively.  o-Aminobenzonitrile is obtained by reduction of the corresponding nitro-compound, which has been specially purified by passing the crude product in benzene through an alumina column, washing the alumina with benzene, concentrating the filtrate and adding light petroleum.

Title: New or improved method of and mechanism for effecting reverse plating on knitting machines
IPC: D04B9/26
Filed: 1932-07-27
Abstract: 388,661. Knitting-machines. HEMPHILL CO., Central Falls, Rhode Island, U.S.A.-(Assignees of Lawson, R. H. ; 55, Cooke Street, Pawtucket, Rhode Island, U.S.A.) July 27, 1932, No. 21219. Convention date, July 30, 1931. [Class 74 (ii).] To reverse plate in circular machines by the co-operative action of needles and sinkers, the needles being preferably controlled in the usual manner, each sinker has mounted below it a jack 43 provided with a number of upper and lower butts or surfaces for engagement by cams. Connected to the sinker cam 9 is a bar or plate 13 by which it may be moved radially in a slotted plate 15 depending from the sinker cap plate 16. This is done by a lever 17 operated by connections from the pattern drum. Immediately prior to resumption of circular knitting, e.g. after knitting stocking heels and toes the cam 9 is projected radially to act on butts 42 of the jacks 43 and position them for further selection. The jacks may also be acted on by other cams, such as 54, 55, and 58 .. 64. Multiple cams 65 act on frangible butts 66, 67, under selective control. Selected jacks having been advanced by a cam 68, the butts 11 of the companion sinkers are acted on by a cam 8 and thus moved outwardly. Subsequently the selected jacks are retracted by the interaction of shoulders 69, 70. By engagement of a cam 72 with these jacks, they and the companion sinkers are then advanced. During this movement the nibs enter between the body and plating yarns for plain plating or above the yarns for reverse plating. Subsequently the jacks and sinkers are retracted by cams 76, 77. Cams 79, 80 restore to position sinkers and jacks accidentally displaced, e.g. during reciprocation. In making heels &c. the jacks are projected by cams 72, 82 during forward (anticlockwise) and reverse (clockwise) strokes respectively. At the start of heel or toe knitting the cam cap 5 is itself advanced by connections from the pattern drum, in order that the sinkers may reach the knocking-over position before the needles have descended, with the result that the heel and toe yarns are measured over the backs of the sinker nibs. Specification 256,612, [Class 74 (ii), Knitting &c.], is referred to.
