IPC: G01F13/00
Filed: 1923-09-07
Abstract: 223,365. Paget, G. Sept. 7, 1923. Fixed-chamber apparatus, in control of supply reservoir, valve systems for and varying quantity measured in.-Relates to containers in which a bucket member is reciprocated within the container for separating the liquid from bulk and directly supplying this liquid to a measuring delivery chamber, and consists of a construction in which the bucket member is operated from outside the container without bringing the liquid into contact with the atmosphere. In one form a cylindrical container 1 is provided with a tightfitting cover 2. A bucket 3 within the container is adapted to be vertically reciprocated by an attached rod 4 passing through a stuffing-box in the cover. Secured to the lower end of the rod 4 within the bucket is a crank arm 9 connected by a pivoted link 10 to the stem 11 of a valve 12. The valve is attached by a cross-piece 18 to a sleeve 17 adapted to slide with the valve in the valve chamber 13. A spring 15 normally urges the valve 12 to close the openings 14 in the valve chamber. Attached outside the container is the delivery chamber 19 connected to the container at its upper end by the pipe 20. The chamber is made of glass supported in a metal holder and is graduated. A draw-off tap 23 is provided. In use, the handle 8 and crank 9 are normally turned by the spring 15 so that the valve 12 is closed and the sleeve 17 drawn within the valve casing. The bucket is moved vertically downwards to dip into the liquid which may enter through a non- return ball valve 24. At the top of the up-stroke the handle 8 is turned and the valve moved to open position, the sleeve being moved outwards and the liquid entering the measuring vessel 19. In a modification the container 1 is provided with a tray which slopes down towards the top of the chamber 19 which is fitted with a cork. The bucket is hinged to the lower end of the rod and moves in vertical guides curved over at the top so that the bucket tips its contents into the tray.

Title: Improvements relating to the preparation of hydrocarbon conversion catalysts and their use
IPC: B01J23/00
Filed: 1963-06-07
Abstract: A catalyst for hydrocarbon conversion is prepared by impregnating a refractory oxide support with a compound of a metal from Group VIa and VIII of the Periodic Table, washing the impregnated support with water to remove all metal cations not chemically bound to the support and drying the washed support.  In a specific example SiO2-Al2O3 support is impregnated with NiNO3 solution, washed with de-ionized water and dried e.g. by blowing air through the heated catalyst. The catalyst may be calcined and then reduced with H2 prior to use.  Pt and Pd we also mentioned as suitable catalyst metals. Support materials may be oxides of Groups II to IV e.g. MgO, boria or TiO2. The support may be calcined before impregnation or after washing and drying.  The temperature of the water for washing may be 15 DEG C. to the boiling point of water at the pressure used.

Patent GB-442528-A (GB)
Title: Improvements in or relating to the manufacture of alkali metal cyanides
IPC: C01C3/10
Filed: 1934-08-08
Abstract: Alkali metal cyanides are obtained by reacting hydrogen cyanide or ammonium cyanide with an anhydrous alkali metal carbonate at elevated temperature, treating the resulting gaseous mixture to remove water vapour and/or carbon dioxide and preferably also ammonia, and either reintroducing the gases resulting from such treatment into the reaction zone or bringing them into contact with a fresh quantity of anhydrous alkali metal carbonate at elevated temperature.  According to a modification, formamide is employed as a starting material, ammonia as well as water vapour and/or carbon dioxide being removed from the resulting gases before their further treatment. Temperatures of 200--500 DEG  C. may be employed.  If desired, a plurality of carbonate containing reaction vessels connected in series may be used, the gases being passed through the entire series with intervening removal of water vapour and/or carbon dioxide.  When the carbonate in the first reaction vessel has been sufficiently converted into cyanide, the hydrocyanic acid gas may be led directly into the second vessel while the exit gases from the last reaction vessel after dehydration are passed into a fresh charge of carbonate. According to an example, formamide vapour and nitrogen are passed through finely divided anhydrous sodium carbonate at 415--435 DEG  C. The ammonia is removed from the exit gases by means of dilute sulphuric acid and the water vapour by means of calcium chloride, the exit gases from the calcium chloride tube containing hydrocyanic acid being passed through a second reaction vessel containing finely divided anhydrous sodium carbonate heated to 445--455 DEG  C.  The exit gases from the second reaction vessel are passed through sodium hydroxide solution to absorb residual hydrocyanic acid.
