Granted: 1904-01-21
Abstract: 5790. Armstrong, Whitworth, & Co., Sir W. G., and Hadcock, A. G. March 12. Ordnance breech mechanism; mountings; loading-appliances.-Relates to automatic guns. The vertically-sliding breech-block a, shown in side elevation, Fig. 1<a>, is operated by a roller a<1> on the crank-arm a<3> of the shaft a'. The operating-lever may be formed in two parts, one part b<1> with which is formed the handle being keyed to the shaft a<4>, and the other part b<2> being free to turn against a spring b<3> when a toe b' upon it meets an arm b<5> on the mounting during the recoil. The toe b' engages with the arm b<5> as the gun runs out, and the shaft a' is turned to open the breech. Instead of making the operating-lever in two parts, the toe b' may be made solid with the lever and the end of the arm on the mounting is pivoted. The wedge-shaped lips c' of the doublearmed extractor c, pivoted on an axis, as shown in the vertical longitudinal section, Fig. 3, are carried under the cartridge rim as the block descends ; the arms are actuated by toes c' on the gun. The breech-block is held down by the bolt d, pushed out by a spring d<2> or, if the spring fails, by a pivoted lever d<3>, as shown in the horizontal section, Fig. 5, until the bolt d is pushed in by the rim of the fresh cartridge engaging with the inclined face d<5> of the lever d'. The breechblock is raised by a spring shown in Fig. 1<a>. The lowest cartridge in the hopper e, Figs. 1 and 1<a>, is supported by its flange resting on projections e<1> and by the spring catches e<3>, Fig. 7, at its forward end until it is pushed forward a short distance by a spring finger e<2> on the injector g, the catches e<3> being released by the stirrup e<4> carrying forward the inclines e<4> against which the catches e<4> bear. The injector is held in the cocked position by its arm g' engaging behind a lever h until this is struck by the empty cartridge case. The injector then moves the lowest cartridge forward, so that it is freed from its supports, as described. While the cartridge is falling, the injector is held by a lever which engages with a projection on the training arm until tripped by the falling cartridge. A tray k, made in the shape of a fork to permit the empty case to drop through, guides the cartridge into the gun.

Patent GB-190413981-A (GB)
Title: Improvements in Processes and Apparatus for Manufacturing Carbonic Acid.
Inventor: BEHRENS ERNST AUGUST
Filed: 1904-06-20
Granted: 1905-06-20
Abstract: 13,981. Behrens, E. A., and Behrens, J. G. June 20. Carbonic acid; potassium carbonate.- Carbon dioxide is produced by burning coke to carbon monoxide in some form of gas-producer, burning this with the calculated quantity of air, and, after condensing any water present, forcing the resulting mixed gases under pressure into a solution of potassium carbonate maintained at the dissociation temperature of potassium-hydrogen carbonate. Potassium-hydrogen carbonate is produced, and when the pressure is removed, the excess of carbon dioxide is evolved and passes to a liquefying- compressor. The energy required to liquefy the carbon dioxide, and to compress the burnt gases, is obtained chiefly from a gas engine in which the producer gases from the coke are consumed, the exhaust being conducted to the potassium-carbonate solution so as to maintain it at the desired temperature, and to convert it into bicarbonate. The carbonate solution is contained in a boiler which it does not quite fill, and which has two openings in the bottom, one for the introduction of the exhaust gases, and another through which the bicarbonate solution continuously flows away to a vessel where, owing to the reduced pressure, it gives up its excess of carbon dioxide, and whence the resulting solution of carbonate is pumped back to the pressure chamber through one of two openings at the top ; the second opening serves for the escape of the unabsorbed gases.
