Patent GB-189827607-A (GB)
Title: Improvements in Railway Signals.
Inventor: TYER EDWARD
Filed: 1898-12-31
Granted: 1899-02-04
Abstract: 27,607. Tyer, E. Dec. 31. Controlling and locking signals ; signalling and communicating between trains ; contacts, mechanical contacts, electric.-Two sliding bars P, P', mounted in the casing A close to one of the rails R, are connected, respectively, by the pulls p<1>, p, to the signal lever in the cabin and to the balance lever L of the ordinary semaphore signal, the free end of the bar P being connected to the counterweight p<4>. A slot in the bar P is formed with a notch to receive a stud on the pawl E, which is pivoted on the bar P<1>. When the stud rests in the notch, the operation of the signal lever lowers the signal, the bars moving together in the casing. The signal is automatically returned to ' danger' by a train passing over the blade s on the counterweighted rocking shaft S, the arm s<2> on this shaft raising the pawl E and releasing the stud from the notch in the bar P. A check pawl engaging the arm s<3> on the rocking shaft prevents the blade s from rising until the signal has been again put to 'safety.' Instead of being controlled directly, the pawl E may be controlled indirectly by an electromagnet energized by the train passing over the blade s, &c. To enable the operation of the signal to be controlled from one or more independent points, the signaloperating rod c is provided with a hinged part c', having a roller c<2> which bears on the rod c<3>, the latter rod bearing on the rod C connected to the balance lever. The part c' is normally held in position on the rod c<3> by the spring h<1> and roller h<2>, but, when the electromagnet H is energized, from the controlling point or points, its armature h forces the part c<1> clear of the rod c<3>, so that the signal cannot be lowered. An alternative arrangement is described, in which the parts are normally disconnected, and are connected when the electromagnet is energized.

Title: Production of Alpha Isatine Anilide and of Isatine.
Inventor: SHILLITO THOMAS RICHARD
Filed: 1899-07-27
Granted: 1900-05-26
Abstract: 15,416. Shillito, T. R., [Geigg & Co., J. R.] July 27. alpha-Isatine anilide and isatine.-Isonitrosoethenyldiphenylamidine is first produced by the gradual addition of chloral hydrate to a mixture of aniline and hydroxylamine hydrochlorate heated to 90‹-100‹ C. When cool, the mixture is poured into ice water, caustic soda lye is added, aniline and bye-products are extracted by ether, the solution is acidified, and the oily isonitroso compound liberated is extracted with ether. The product, when purified, is a slightly-yellowish crystalline powder, which melts at 131‹-132‹ C. alpha-Isatine anilide is produced by dissolving the foregoing isonitroso compound in concentrated sulphuric acid at 40‹-50‹ C.. and then heating the mixture to 100‹-105‹ C. It is precipitated by pouring the reaction mixture, when cool, into an iced solution of sodium carbonate, and the precipitate is filtered off and dried at a low temperature. The anilide forms a cinnabar red hydrazone with phenylhydrazine. By boiling alpha-isatine anilide with diluted sulphuric or other mineral acid, isatine itself is obtained.

Title: An Improved Manufacture of Alcoholic Spirits and Apparatus therefor.
Inventor: BARBET EMILE
Filed: 1899-08-09
Granted: 1900-04-28
Abstract: 16,233. Barbet, E. Aug. 9. Drawings to Specification. Spirits.-The object is to produce on the large scale from grain, potatoes, beet-roots, artichokes, and other comparatively-cheap agricultural products a spirit which shall have the flavour of the best brandy. The starch or sugar is first extracted from these materials by ordinary means, and the starch is saccharified by boiling it with sulphuric acid, first in an open vessel, and then in a closed vessel, after which it is filtered and decolorized. The wort thus obtained is flavoured by the addition of the lees of fruit juices from which the spirit has been distilled ; wine, cider, dry raisins, figs, apples, cream of tartar, citric or malic acid, and ammonium phosphate may also be employed for this purpose. The fermentation is effected by yeast, which may be prepared as described in Specification No. 16,159, A.D. 1899. The wort is matured before distillation by heating it while it is flowing through a series of vessels, and the carbonic acid which collects in the fermenting vessels is also forced into the wort. The wort is distilled in any ordinary way, and the distillate may be re-distilled and is then allowed to mature in tuns and casks.
