Title: Improvements in or relating to railway car couplers
IPC: B61G3/20
Filed: 1930-09-05
Abstract: 358,223. Automatic couplings for railway vehicles. NATIONAL MALLEABLE & STEEL CASTINGS CO., 10600, Quincy Avenue, Cleveland, Ohio, U.S.A.-(Assignees of Bazeley, A. J. ; 9718, Logan Court, Cleveland, Ohio, U.S.A.) Sept. 5, 1930, No. 26622. Convention date, Sept. 9, 1929. [Class 103 (v).] In an automatic coupling for railway vehicles of the rigid-jaw type, e.g. as described in Specification 252,567, [Class 103 (v), Railway &c. vehicles, Draught &c. appliances for], in which co-operating hooks and shoulders engage by a lateral swinging movement and each coupler-head is fitted with a gravity sliding lock, the latter is adapted to be retained in a raised or inoperative position for shunting and like purposes through the medium of a pivoted latch 21 that engages a member, such as a hand-wheel 10, of the uncoupling mechanism, and is maintained in engagement therewith by an independently movable weighted arm 23. In the construction shown the wheel 10 is secured to a transverse shaft 6 on which is arranged to wind and unwind a chain 11 connected to the lock actuating lever 13. A second chain 14 associated with a counterweight 15 is adapted to restore the wheel to its initial position after an uncoupling operation has been effected and the latch 21 subsequently released, while a further chain 17, Fig. 3, prevents rotation of the wheel in the wrong direction at the commencement of an uncoupling operation. The notch 29 on the wheel 10 with which the latch 21 engages is furnished by a pair of spaced dogs 28 adjustable in slots 31 and, in the normal or operative position of the couplerhead, Fig. 1, the wheel is so positioned that the chain 11 is slack. By rotating the wheel 10 through the necessary angle, in the example shown 1<1>/6 revolutions approximately, the latch 21 is allowed to drop into the notch 29 as the chain 11 becomes taut, and the lock is thus held in an inoperative position as long as is desired. In a modification a series of stops designed to co-operate with the latch 21 is formed integrally with the wheel 10, and a hand-lever is provided for effecting the rotation of the wheel.

Title: Improvements in and relating to the conversion of sulphur dioxide to sulphur trioxide
Inventor: DAVIES PHINEAS
IPC: B01J23/22
Filed: 1953-10-02
Abstract: Sulphur trioxide is produced by contacting a mixture of sulphur dioxide and a gas containing free oxygen with a catalyst comprising oxides of vanadium, potassium, and silicon, the molar ratio of K2O : V2O5 being from 4.5 : 1 to 6 : 1 and the reaction being initiated at a temperature within the range of 380 DEG  to 400 DEG C.  At temperatures of 380 DEG , 390 DEG , and 400 DEG , the optimum K2O : V2O5 ratios are 5.4 : 1, 5 : 1, and 4.5 : respectively.  The oxides of vanadium, potassium, and silicon may be present in combination, e.g. as potassium silicate or potassium vanadate.  The catalyst is prepared by adding potassium silicate solution to dilute sulphuric acid, at a pH not greater than 4, to form a silica sol, mixing the sol with a soluble vanadium compound and coprecipitating silica and an insoluble vanadium compound by the addition of ammonia.  Suitable soluble vanadium compounds are vanadyl sulphate, vanadyl chloride, vanadyl oxalate, and ammonium vanadate.  The reactant concentrations are preferably controlled to give a gel product free from supernatant liquid.  A preferred vanadium content is 6-7.5 per cent by weight, as V2O5.  The catalyst may contain an inert filler, such as kieselguhr, in an amount of up to 50 per cent by weight.  The oxidation process may be carried out in three successive reaction zones, the inlet temperature to each zone being, for example, 380 DEG C. and the outlet temperature from the third zone 410 DEG C.  The composition of the catalyst may vary throughout each bed, but especially the third bed, so as to give maximum conversion at all parts of the bed. Specification 705,615 is referred to.

Title: Process of manufacturing fuel and the product produced by such process
IPC: C10L5/14
Filed: 1924-11-17
Abstract: 228,862. Trent, W. E. Feb. 9, 1924, [Convention date]. Composition fuel.-Finely pulverized fuel such as anthracite, bituminous coal, lignite, coke breeze, or ashes, after being wetted as by suspension in water is treated by agitating with a hydrocarbon agent comprising hydrocarbons of both high and low boiling points, in sufficient quantity to exclude the water from the coal and hydrocarbon agglomerate, which is subjected to a low temperature heat treatment so as to vaporize the low bolling point fraction without vaporizing the high boiling point fraction or the volatile ingredients of the coal. Plastic masses, freed from water and in large part from impurities, are formed by the agitation treatment of size varying from one-eighth of an inch to two inches in diameter according to the amount of water present, the violence of agitation and the temperature. The masses are gradually heated to a temperature depending upon the vaporizing point of the less volatile constituent of the hydrocarbon, e.g. about 300‹ C., the whole of the more volatile constituent being distilled. Or the treatment may be such as merely to remove the low boiling point fraction from the exterior portion of the masses. When cool, the coal particles containing substantially all their original volatile content form a hard smokeless fuel with the normally solid fraction. Kerosene, benzol, or light fuel oils may be used as the low boiling point fraction, or heavy fuel oils or refinery residues may be used which contain fractions sufficiently solid after the heat treatment. In an example 200 grams of coal of 200 mesh in fineness are treated in aqueous suspension with 80 grams of a blended oil containing two-thirds by weight of kerosene and one third of asphalt or similar normally solid substance. The amalgamated masses may be passed through moulding machines before being heated. The vaporized hydrocarbon mav be condensed and re-used in the agglomerating step. Specification 151.236 is referred to.
