Title: Improvements in the Production of Oxypurines and their Alkyl Derivatives from Trichloropurine.
Inventor: JOHNSON JAMES YATE
Filed: 1897-10-09
Granted: 1898-10-08
Abstract: 23,227. Johnson, J. Y., [Boehringer & S÷hne, C. F.]. Oct. 9. Hypoxanthine, xanthine, and alkyl derivatives thereof are prepared from trichloropurine by the following processes :-2 8 - dichloro - 6- ethoxy- or methoxy-purine is first obtained by acting upon trichloropurine with an ethyl or methyl alcohol solution of sodium at the ordinary temperature, and this compound is converted into 6-oxy-2 :8- dichloropurine by heating it with hydrochloric acid. The latter compound may also be obtained directly by heating trichloropurine with an aqueous solution of an alkali at 100‹ C. for several hours. Hypoxanthine is then produced by reducing 6-oxy-2 : 8 dichloropurine or 2 : 8 dichloro-6- ethoxypurine with hydriodic acid and phosphonium iodide or yellow phosphorus. Dimethylhypoxanthine is prepared by heating 6-oxy-2 : 8- dichloropurine with potash lye and methyl iodide in a closed vessel. When trichloropurine is heated with excess of sodium ethylate or methylate in a closed vessel at 100‹ C. for several hours it is converted into 8-chloro-2 : 6-diethoxy- or dimethoxypurine. This compound is reduced to 2 : 6-diethoxy- or dimethoxy - purine by acting upon it with hydriodic acid and phosphonium iodide, and on subsequently heating the mixture upon a water bath the ethyl or methyl groups are split off, and xanthine is formed. Chloroxanthine is obtained by heating 8 - chloro- 2 : 6 - diethoxypurine with hydrochloric acid, and it is converted into chlorocaffeine, which is identical with the compound obtained by chlorinating natural caffeine, by heating it with potash lye and methyl iodide at 80‹ C. in a closed vessel for two hours.

Granted: 1899-07-01
Abstract: 18,233. Luck, A., and Cross, C. F. Aug. 24. Nitro-cellulose is converted into hard non-fibrous grains by treating fibrous grains with a solvent diluted with a non-solvent liquid, as for instance acetone mixed with one-tenth of its volume of water, for about ten minutes, with gentle agitation. The liquid may be heated or boiled, to increase the subsequent hardening. The mixture is then diluted with more of the non-solvent liquid, or the solvent is distilled off, when the grains become hard and compact. The grains are afterwards washed and dried. The fibrous grains may be made from highly-nitrated cotton in a revolving drum or pill-coating machine ; the cotton may be mixed with starch paste and passed through a sieve. The grains are preferably dried before treatment with the solvent mixture. Specification No. 5286, A.D. 1898, is referred to, describing the use of partial solvents for rendering nitro-cellulose non-fibrous, and purifying it.

Title: Improvements in Signalling Apparatus for Railways and the like.
Inventor: MARA WILLIAM PATRICK
Filed: 1900-04-11
Granted: 1901-04-11
Abstract: 6833. Mara, W. P. April 11. Signals on engines and trains; indicators and repeaters, signal; contacts, mechanical ; contacts, electric.-Relates to signalling-apparatus for railways, tramways, &c., applicable for use in conjunction with, or in substitution for, the ordinary signals, to indicate to the driver the positions of the ordinary signals, or whether the line is ' blocked ' or 'clear.' The indications are given on the engine &c. by means of miniature semaphores, electric or other bells, whistles, or the like. When employed in conjunction with the ordinary signals, one or more pairs (preferably a series of pairs) of bell-crank levers A, B are mounted near the rails, as shown, in the neighbourhood of the ordinary signals. Each lever is provided with a contactarm a<4>, b<4>, adapted to operate corresponding depending bars c<4> on each side of the engine. One arm of each lever A is connected by a rod &c. to the ordinary signal-operating mechanism, and another arm is connected by the rod a<3> to an arm of the lever B, so that both levers are worked simultaneously, the lever A being operative when B is inoperative, and vice versÔ. The levers A are intended to give ' danger' signals, and the levers B line clear signals. Each depending bar c<4> is preferably of greater length than the distance between two consecutive levers A, and is carried by levers c<1>, pivoted on brackets on the engine. The arms a<4>, b<4> of the levers at the 'distant' signal may differ in length from those at the ' home' signal, so as to distinguish between the two signals by the difference in the operative movement of the levers c<1>. Fig. 5 shows a contact-mechanism D, employed for operating electric bells and visible indicators on the engine, the spring-controlled bolt d' being connected by the pin d to the upper arm of the lever c<1>. When the lever is operated, by contact of its bar c<4> with a lever A or B at a ' distant' signal, the bolt d<1> raises the lever d<5> so that it connects the contacts d<7>, thereby completing the circuit of a bell and indicator &c. At a 'home' signal, the bolt d' actuates both levers d<5>, d<6> to connect their respective contacts d', d<8>, so completing two signalling-circuits. In the arrangement shown in Figs. 2 and 3, a mechanical device is employed, a shoulder on the bolt d' engaging forked arms on the rods d<9>, d<10>, d<11>, d<15>, so that the rods are oscillated when the bolt is operated. This movement may effect the operation of a miniature semaphore indicator &c., by means of cords &c. connected to arms on the rods d<9> &c. The application of the invention for operating the indicator described in Specification No. 16,240, A.D. 1900, is described. In a modification of the bell-crank levers A, adapted to enable the apparatus to be put out of or into action as required, each lever is made in two parts, which can be moved independentiy, the upper part carrying the arm a', while the lower part is connected to the rod a<3>.
