Granted: 1900-06-23
Abstract: 23,340. Haddan, R., [Roubertie, P. J. J.]. Nov. 22. Chlorine.-Relates to a process or series of operations for obtaining caustic soda or potash and chlorine, in which all the materials used are regenerated for re-use. (1) A solution of sodium or potassium chloride is decomposed by silver oxide or carbonate, forming caustic or carbonate i alkali and silver chloride. (2) The silver oxide or carbonate is preferably regenerated as follows:- (a) The chloride is decomposed by means of powdered iron with a slight excess ot water, whereby silver is precipitated and iron chloride obtained. (b) After separating the silver by filtration, the iron chloride is evaporated and dried in an oven out uf contact with air. (c) Air previously freed from carbonic acid, dried, and heated is passed through the oven, chlorine being evolved and led to lime chambers. (d) The iron oxide left is reduced by carbonic oxide to the metallic state in the form of powder for re-use. (e) The metallic silver obtained in the form of powder is treated with nitric acid, and the silver nitrate formed is treated with milk of lime, baryta, or strontia. Silver oxide is precipitated for re-use. (f) The nitrate is dried and calcined, producing lime, baryta, or strontia for re-use, and liberating nitrous gases, which are condensed to reform nitric acid. (3) In another method, the silver oxide or carbonate is regenerated as follows :-(a) Sulphuric acid is added to the silver chloride to form silver sulphate, and hydrochloric acid, which is condensed. (b) The silver sulphate is treated with ammonia or ammonium carbonate, whereby silver oxide or carbonate is precipitated for re-use, and ammonium sulphate remains in solution. (c) The ammonium sulphate is treated with lime, obtaining ammonia for re-use and calcium sulphate as a bye-product. A suitable apparatus for carrying out the operations, in which the silver can be decomposed and regenerated without removal, consists of a vessel a having an agitator c, inlet and outlet openings i for gases, and inclined bottom, and an outlet for liquids provided with a casing 2 in which a cellulose or asbestos layer is placed between the perforated side 2<a> and the removable perforated plate 3. The cock 1 is attached to the filter.

Title: Improvements in or relating to Friction Clutches particularly adapted for Hoisting and like Apparatus.
Inventor: BOLZANI ANTON
Filed: 1902-06-10
Granted: 1903-06-10
Abstract: 13,206. Bolzani, A. June 10. Lifts; brakes.-A friction clutch for operating a lift, hoist, &c. is combined with a safety apparatus which prevents descent of the load when the driving-effort ceases. Two eccentrics b, f, separated by a swinging ring c, are fitted within a casing e having ratchet teeth engaged by a pawl l. The eccentric b, loose on the shaft, receives the driving-effort by means of a wheel x &c., and, in the act of rotating, wedges the eccentric f against the casing e, which consequently rotates in the direction of the arrow together with the two eccentrics. The shaft a, which works the lift &c., is driven from the eccentric f by a pin g engaging a slot in a disc h keyed on the shaft. If the driving-effort ceases, backward rotation of the shaft is prevented by the pawl and the wedging action of the eccentrics. If, however, the driving- eccentric b is rotated backwards, the wedging action is slackened sufficiently to allow the driven eccentric f to follow the motion of the eccentric b and lower the load. The arrangement may be used to couple co-linear shafts.
