Title: Improvements in and relating to the Separation of Nitrogen from Air.
Inventor: HEYS WILLIAM GEORGE
IPC: B01D53/46
Filed: 1910-10-21
Granted: 1911-04-06
Abstract: 24,413. Heys, W. G., [Nitrogen Co.]. Oct. 21. Nitrogen is obtained continuously from air, either pure or partly deprived of its oxygen, by oxidizing molten potassium or sodium cyanide, single or mixed, therewith, while simultaneously reducing the resultant cyanate with certain metals, say iron or zinc, or carbon. The apparatus for carrying out this process comprises a shallow pot 1 of copper &c., which may be fitted with a refractory lining 2 of magnesia or alumina brick &c. The gas-tight cover 3 carries on its underside a bell 4, and inside this a heavy wire-cloth basket 6 which communicates with a closable hopper 5 on the outside. The pot 1 is nearly filled with molten sodium cyanide 9, and the basket 6 is filled with carbon 10, say anthracite. The apparatus is heated in a furnace, or, in a modification, by passing an alternating electric current between the carbon 10 and the pot 1. The carbon electrodes, embedded in the carbon 10, may be a secondary source of carbon, or the coal may be omitted. In operation, the air, previously deprived of all moisture and carbon dioxide, passes through a pipe 7 into the space over the cyanide, passes slowly thereon, being forced to take a circuitous path by means of suitable baffles attached to the cover 3 and dipping into the cyanide. The oxygen having been extracted by the conversion of a portion of the cyanide into cyanate, the nitrogen passes out through an exit pipe 8. The molten cyanate produced on the surface of the melt diffuses therethrough and, coming into contact with the carbon 10, is reduced again to cyanide with evolution of carbon monoxide; this gas is collected by the bell 4, and passing up through the carbon, escapes through a pipe 13 attached to the hopper 5. Any particles of carbon falling out of the basket 6 are prevented from passing from under the bell 4 by an annular rib 15 on the bottom of the pot 1.

Granted: 1912-03-28
Abstract: 10,232. Bloxam, A. G., [Thomson & Co., J.]. April 27. Rolling for graining. In a machine for impressing a grain on leather, a short, smooth roller presses the leather on to an underlying pattern sheet, and an elastic sheet is placed under the roller to distribute the pressure and prevent the formation of streaks as the whole surface of the leather is treated in successive narrow strips. The machine is shown in side elevation and transverse section in Figs. 1 and 2. The upper movable beam a carries tension links b which are pivoted to elbow levers d on the fixed beam c, these being tied by a link e and attached, by a chain and leverage pulleys g, to a weight f, which thus cause a downward pressure to be transmitted through the beam a to the carriage h. These carry narrow pressing-rolls i, which are linked by members l to the nuts k of the traversing-screw which rotates in fixed bearings. The table p carries the pattern plate n and is supported by wheels q on transverse rails r. The leather is laid on the pattern plate and is overlaid by a rubber or like elastic sheet upon which the smooth rollers i bear. The underside of the table has adjustable stop-pieces u adapted to engage a pawl v on the lower beam c. When the pawl is disengaged by depression of the pedal m, the table may be traversed by hand or automatically to bring an untreated strip of leather under the rollers. The table is supported by springs s and during the rolling operation these yield sufficiently to allow the table to rest on the beam c, which thus takes the load. The table is also guided transversely by rollers t.

Inventor: SUTTON GILBERT WILLIAM
IPC: B29C65/00
Filed: 1911-12-07
Granted: 1912-12-09
Abstract: 27,424. Sutton, G. W. Dec. 7. Latex, coagulating.-Relates to apparatus for smoking and coagulating latex in which the latex is fed from a closed light-excluding container on to an endless band travelling through a smoke chamber in which the smoke is forced in a direction opposite to the travel of the hand. The latex container 2 is gradually tilted through screw-and-nut and worm gearing connected to the shaft 16. When the container is empty, the descent of a cross-bar 7 on to a lever 13 automatically unclutches the gearing from the shaft 16. When thus disconnected, the container may be tilted by hand, if desired, through the gearing. The latex falls upon an inclined travelling band 19 formed with flanged edges to retain the latex. A fan 26 forces smoke from a box 30 through slits in a flue 20 in a direction opposed to that of the band, and the smoke returns beneath the band as shown by the arrows. The uncoagulated latex may fall on to a second band 19, and so on. The bands or conveyers are heated by steam or hot water supplied through pipes 22. Specification 9190/11 is referred to.

Granted: 1912-01-30
Abstract: 354. Dawson, Sir A. T., and Buckham, G. T. Jan. 30, 1911. Dismounting; recoil apparatus. - Relates to siege-gun mountings, for example of the kind described in Specification 2384/11, and consists in apparatus for relieving the connexion between the gun-barrel and the hydro-pneumatic run-out recuperator of the pressure of the recuperator when the connecting bolt is to be removed. The apparatus may also be used to take the pressure off the gland through which the rod of the floating-piston passes, when the gland requires attention. Means are also provided for supporting the ram of the recuperator when the gun is removed from the mounting. The hollow ram f of the recuperator is connected to the gun-barrel A by a cross-head F<2> and bolt f<2>, and is provided at its front end with a gland F<Î> through which passes the rod f<1> of the floating piston that separates the air in the rear end of the recuperator cylinder from the liquid in the front end, and in the hollow ram f. To take the pressure of the ram off the cross-head F<2> and bolt f<2>, a forked member F<3> is hooked on to studs b on the cradle B, and pressure is applied by a set-screw f<3> to the ram f through a cap F<4> fitted upon the end of the rod f<1>, and bearing upon the end of the ram. When the cap is absent, the set-screw f<3> bears upon the end of the rod f<1> and relieves the liquid in the ram f of pressure, so that the gland F<Î> may be attended to. When the gun is in the run-out position, wings f<2Î> on the cross-head F<2> enter keyways b<1> in the cradle B and bring up against nuts b<2Î> on the inner ends of the studs b. The ram f is thus supported when the gun-barrel is dismounted.

Title: Improvements in Furnaces for Heating Copper Ingots and for other like uses.
Inventor: GIBBONS GEORGE BENJAMIN ALBERT
IPC: C21D9/00
Filed: 1912-03-25
Granted: 1913-02-06
Abstract: 7203. Gibbons, G. B. A., and Masters, R. March 25. Metal-heating furnaces; hearths.-A regenerative gas furnace for heating copper ingots, annealing iron castings, and for like purposes, consists of a circular dome - topped heating- chamber having in its floor one or more gas up-cast shafts and having a regenerator built in an annular shape underneath the floor, the hot air outlets from which lead into the upcast shaft. or shafts, there being waste-gas outlets in the circular wall of the furnace communicating by down-cast passages with the regenerator. In the furnace shown in Figs. 1 and 4, of which Fig. 4 is a sectional plan on the line Y Y of Fig. 1, gas from a producer 6 passes up a central up-cast shaft 4, where it is supplied with secondary air from ports 13 in the upper part 5 of the shaft. The combustion products pass over the hearth 3 and leave by down-cast passages 15, which open into the side walls of the furnace immediately above the hearth. These passages, which are preferably arranged in pairs, as shown, between the feeding-holes 17, lead to an annular waste-gas flue 14, from which down-cast passages 18, Fig. 4, lead to the flue 19. Air for secondary combustion is first heated in zig-zag passages 35 in the walls of the producer, and then passes to annular zigzag passages regeneratively heated by the waste-gas flue 14. As shown in Fig. 4, these passages are arranged in two sections, in one of which the air, arriving by up-cast passages 34 from one set of zigzag passages 35, circulates in the passages 22, 23, 24, and passes by ducts 42 to the ports 13, the other section being similarly arranged. In the form shown in Fig. 5, the furnace is provided with a revolving hearth, formed of sector-shaped plates 43 with a refractory covering 47, and having sand seals 49, 51 at its outer and inner peripheries. It is supported on rollers 53, 54 and kept in position by horizontal rollers 59, which contact with a circular rim 61 on the underside of the table. A toothed ring 62 gearing with a bevelled pinion provides the driving- means. The waste-gas flues 15 communicate by radial flues 71 with an annular flue 14 between the annular air-passages 72, 73. The secondary air flows downwards through the outer passage 72, through radial passages crossing the flue 14, upwards through the inner passage 73, and thence through ducts 42 to the ports 13. An annular space 69 filled with heat-insulating material minimizes heat radiation from the gas up-cast shaft 4.

Abstract: 7368. Bruce, C. W. W. March 26. [Cognate Application, 18,884/12.] Bottles, washing.-Bottles and like vessels are packed horizontally between adjustable partitions mounted in a fixed semicircular soaking-tank and are moved round within the tank by projections attached to the partitions. Fig. 2 shows an apparatus of this kind having a fixed tank provided with a renewable liner, a well v, and bearings for a horizontal shaft b, which can be rotated from a hand wheel through the medium of a worm n. The partitions c are loosely-mounted or feathered on the shaft and are fitted with split collars d which surround the shaft and carry pinions e engaging a rack thereon. By rotating the pinions through the medium of the hand-wheels h, the partitions can be spaced on the shaft to receive bottles of any length. In the form shown, the split collars are clamped to the shaft bv hand-nuts j. The annular space through which the bottles travel is completed by overlapping plates p carried by the partitions. To move the bottles round in the tank, curved push-plates q carried by the partitions are bent up at their ends to engage the row of bottles next to the periphery of the tank. The plates q have a pin-and-slot connexion with plates q<1> for purposes of adjustment. In operation, the shaft and partitions are reciprocated by the worm gear to deliver a few bottles at each stroke, more bottles being added at the inlet side of the tank between each stroke. The pushing action may be assisted by piling the bottles at the inlet side of the tank higher than at the outlet side, thus forming a ' head ' of bottles.
