Patent GB-190821857-A (GB)
Title: Improvements in and relating to Signals for Railway and like Systems.
Filed: 1908-10-15
Granted: 1909-07-01
Abstract: 21,857. British Thomson-Houston Co., [General Electric Co.]. Oct. 15. Semaphore signals; controlling signals.-A threeposition signal operated electrically is provided with contacts on the spindle, which are set so as to close circuits to the motor and clutch magnet to stop the signal at 'caution' if required by a train backing into the section, without it being first put to 'danger' and then replaced by the motor. The signal is fast on the spindle C which carries contacts h coacting with fixed contacts H, and also an arm E supporting an electro-magnet F, the armature e<1> of which holds the tooth ein position to engage the projections b on the wheel B which is driven by the motor A. When a train is in a section, the clutch magnet F is de-energized and the signal is at ' danger.' When the section is cleared, the motor drives the wheel B and one of the studs b engages the tooth e and drives the signal to caution,' where it remains until, as the train clears the advance section, the motor and clutch magnet circuits are so energized as to drive it to 'clear.' The clutch magnet has two windings, one of which is in series with the motor so as to strengthen the magnet when the motor is driving. In order to stop the signal at ' caution' on its way from' clear' without first putting it to danger,' the contacts are so arranged that the signal passes just beyond its caution' position ; as it passes this position, the motor and magnet circuits are closed, the magnet being then sufficiently strong to hold the tooth e as the latter engages the studs b. With a semaphore having an angular difference in position of forty-five degrees, seven studs b give sufficient excess movement to allow the magnet to be strengthened to hold the armature e<1> against the force of the blow as the tooth e engages the stud b.

Granted: 1910-05-05
Abstract: 10,667. Spigno, G. B. M. May 5. Processes and materials for treating hides and skins.-Leather that has been tanned by a non- fatty vegetable process is treated with solutions of glue or gelatine, free from lime and iron, whereby the free tannin in the hide is fixed and decolorizing is effected without the employment of acids or salts. The hides are dried prior to the glue treatment, without being rinsed free from the tanning-solution. The glue or gelatine bath may be of animal or vegetable origin, and may be applied to the hides between successive dippings in the ordinary tanning-bath. Fleshings, shavings, or other gelatinous substances may be acted on by hot water in the bath in substitution for ready-made glue &c. The application to sole leather is instanced by treatment with a mixture of baryta white and a glue solution containing barium chloride, sodium borate, whale oil, and glucose in stated proportions. According to the Provisional Specification, the hides may sometimes be rinsed and pressed before being treated with the glue, or they may be rinsed with formaldehyde or other substances that will fix the gelatinous material; also it is stated that ordinary glue may be employed, and that the treatment is applicable to mineraltanned hides.

Title: Improvements in the Manufacture of Ammonia, and Aluminium Compounds, from Mixtures containing Aluminium Nitride.
Inventor: JOHNSON JAMES YATE
IPC: C01F7/02
Filed: 1910-03-03
Granted: 1911-03-03
Abstract: 5382. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. March 3. Ammonia; ammonium salts.-Ammonia and practically pure aluminium compounds are obtained from raw or impure mixtures containing aluminium nitride by treating the mixtures with such limited quantities of acid or alkali, or by carrying out the reaction under such mild conditions, that the aluminium nitride alone is decomposed. The use of mild conditions consists in a suitable choice of concentration of the ingredients, and the temperature and time during which the reaction takes place. The bodies treated are such as are obtained by heating minerals containing aluminium with carbon in a current of nitrogen gas, and the impurities are mainly nitrides, carbides, and oxides of silicon and titanium. When an acid is used, the amount added may be such as to convert the ammonia and the aluminium into the salt of the acid; or a less quantity of acid may be employed, the aluminium salt in this case reacting with more aluminium nitride. Other salts, such as iron chloride, of which the bases are precipitated by ammonia, may be used, and acid salts may be also employed for carrying out the process. Further, carbonic acid, or an acid incapable of forming stable salts with aluminium, may be used. When using an alkaline reagent, the amount used may be such as will form aluminate with the aluminium, although a smaller quantity may be employed. The aluminate solution is filtered off, and any undissolved aluminium compound can be brought into solution by means of an acid, or an alkali. Double salts may be prepared from the raw product thus obtained by adding an acid, or an acid salt, and any alkali. It is advantageous, especially when a limited quantity of alkali is used, to add a neutral salt, which has the effect of increasing the evolution of ammonia, and this addition is particularly advantageous when preparing double salts. The raw nitride may be first treated with steam or water, or it may be purified by any suitable process before being treated with acid or an alkali.

Abstract: 7053. Baumann, A. March 22, 1909, [Convention date]. Aerostats.-The stiffening-frame of aerostats is arranged in the air - bag or ballonet, the gas-bag being strengthened by rigid or inflated flexible pipes secured thereto longitudinally. The framing of the air-bag b comprises longitudinal tubes or bars c connected together by cross-tubes d, f arranged as shown. The gasbag a is stiffened by pipes arranged inside as at i, or preferably outside as at h, these pipes being connected to the framing by gas-tight material, or, as shown, by ropes k, l. The framing c, d, f, regarded as a whole, may be of T, I, or V form in cross-section. The air and gas-bags may be of the same length and may have pointed ends, or an independent collapsible or rigid gas-bag may be provided at each end. The dimensions are chosen so that the gas-bag can be arranged in longitudinal folds around the air-bag, thus diminishing the air-space between them sufficiently to prevent the purity of the hydrogen gas from being impaired. The air-bag may be placed in the lower part of the gas-bag, or may project below the lower wall thereof. The gas and air bags may be divided into compartments by partitions. The tubular framing may be filled with compressed gas; or the exhaust gases from the motor, or the cooling-fluid, may pass through the tubes. Cars.-The car n may be connected to the gas-bag by gas-tight material, or by ropes m as shown; or the ropes may pass round the outside of the gas-bag. The lower tubes f of the airbag framing described above may be provided with a floor, so that the air-bag may serve to contain passengers, stores, or machines.
