Patent GB-189823410-A (GB)
Title: Improvements in Explosive Signalling Apparatus for Railways.
Filed: 1898-11-07
Granted: 1899-12-07
Abstract: 23,410. Electric Fog Signal Syndicate and Sykes, W. R. Nov. 7. Fog and audible signals; indicators and repeaters, signal; signalling to cabins; contacts, electric.- Relates to electrically-controlled fog-signalling apparatus for railways. The signal cartridges are mounted in pairs in the chambers a of the gravityoperated carrier A, which is allowed to fall, stepby-step, to bring the pairs of cartridges successively into position to be fired by the hammers C acting on the firing-pins F. The hammers are normally held in the raised or 'set' position, as shown, by the latch d, and are released, to fire the cartridges, when the latch is raised by the electromagnet D. The circuit of this magnet has two gaps, one on the signal post, which is closed when the ordinary signal is at 'danger,' and the other at a treadle contact close to one of the rails. When the signal is at 'danger,' the circuit is completed, and a pair of cartridges fired, by a train passing over the treadle. The explosion of the cartridges acts through the bell receiver H, lever H<1>, band h<2>, and pulleys H<2>, I, to re-set the hammers. Should the re-setting apparatus fail to act, a spring r, which is normally supported by the cam R on the hammer spindle, completes, with the contact r<1>, the circuit of an alarm bell in the signal cabin. The carrier A is mounted in vertical guides B, and is held steady by the roller p<1> on the weighted lever P. The downward movement of the carrier is controlled by the Y-shaped escapement lever K, acting in conjunction with oppositely-directed ratchets on the sides of the carrier. The weighted lever M, which actuates the escapement to release the carrier, is normally held by the latch n on the armature of the electromagnet O. The hammers C in falling actuate the switch U, which breaks the circuit of the magnet D and closes a gap in the circuit of the magnet 0, the latter circuit being finally completed, to actuate the feed-mechanism, by the train passing over a second treadle contact located a suitable distance in advance of that controlling the magnet D. For single lines &c., a treadle controlling the magnet 0 is placed on each side of that controlling the magnet D, the first of these treadles passed over by a particular train being inoperative owing to the position of the switch U. The switch is re-set to its normal position by the lever K. When the top of the carrier A falls below a certain level, it engages a lever which completes the circuit of the alarm bell in the cabin, indicating that the cartridges in the carrier are almost exhausted. The apparatus is re-charged by inserting a fresh carrier at the top of the guides B, the first being left to fall out below when exhausted. When not required the apparatus is cut out of operation by a switch in the signal cabin.

Abstract: 25,319. Reuse, J. Nov. 30. Cigars.-Relates to machines for making the fillers of cigars. Fig. 1 shows a side elevation, and Fig. 3 a plan of the machine with some parts removed. On a bed A is mounted a sliding frame a to which is pivoted at f<1> a cover-plate f which carries the plunger g. Sliding within the frame a is a second frame b, which is normally prevented from moving relatively to the frame a by ' detent lever c. The detent is drawn back by the contact-pin c' with the fixed bevelled surface c' when the frame a advances. A third sliding frame d is free to move within the frame b, and is provided with a handle e. Sufficient tobacco to form one filler is placed in the space X between the curved surfaces b<1>, d<1> of the parts b, d. By means of the handle e the frame d is pushed forward, compressing the tobacco between the curved surfaces until the pressure causes the frame a to advance, when the detent c releases the frame b. The advance of the frame a is limited by a slot a<2> in which moves the stop a<1>, the frame b continuing to advance until the stop f<2> is reached. The tobacco is then forced out from between the surfaces a<1>, b<1> by the descent of the plunger g, and falls into a pocket i<1> in the swinging part i of the rolling-table h. By means of a treadle-lever and the gearing s, r<1>, the levers r which carry the roller g are caused to advance, and the tobacco is rolled in a leaf laid on the rolling-apron l. Springs p and cords o return the slack in the apron to the pocket i<1> after a filler has been rolled.

Abstract: 26,261. Johnson, J. Y., [Boehringer & Soehne, C. F.]. Dec. 12. Chloro-paraxanthine and paraxanthine.-Caffeine or chloro-caffeine is heated with about 1¢ molecular proportions of phosphorus pentachloride and a solvent such as phosphorus oxychloride or chloroform, at about 150‹-155‹ C., for 8 to 9 hours, in an autoclave. After evaporation of the product in vacuo and further purification, 3<1> : 8-dichlorocaffeine (in which the methyl group attached to the nitrogen-3 is chlorinated) is obtained in colourless crystals which melt at 144‹-145‹À5 C. This product is boiled with water until formaldehyde is no longer evolved, and the solution after filtration is treated with charcoal and evaporated to half its bulk, whereupon crystals of chloro-paraxanthine (1 : 7-dimethyl-8-chloro-caffeine) are obtained which melt with evolution of gas at 281‹ C. When reduced by hydriodic acid and phosphonium iodide chloro-paraxanthine is reduced to paraxanthine which is identical with the known compound.
