Title: Improvements relating to apparatus for drying air for fluid pressure braking apparatus
IPC: B01D53/26
Filed: 1944-03-09
Abstract: 577,050. Drying air for railway brake equipments. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and CADMAN. N. G. March 9, 1944, No. 4390. [Class 34 (i)] [Also in Groups III and XXXIV] In apparatus for removing moisture from compressed air used for operating fluidpressure railway brake equipments by means of silica gel &c. the silica gel is regenerated by the simultaneous application of heat and the passage therethrough of a current of exhaust air from said equipment. In the construction shown, in which the heating of the silica gel is effected by the heat evolved by the compression of the air to be dried, two dehydrator elements 1, 2 are employed, each comprising a casing 4 containing a body 3 of silica gel within which is embedded a multi-tubular heater 5, the pipes leading to and from the elements being interconnected by rotary change-over valves 6, 7. The valve 6 controls pipes 14, 21 respectively leading from the air compressor, not shown, and the exhaust port of the brake control valve 18, and the valve 7 controls pipes 17, 25 respectively leading to a compressed air reservoir, not shown, in communication with the valve 18 through a pipe 19, and to atmosphere. With the valves 6, 7 in the positions shown, air from the compressor passes through the pipes 14, 26, the heater 5 in the inoperative dehydrator 2, the pipe 15, the silica gel in the operative dehydrator 1, the pipes 16, 17, the compressed air reservoir and the pipe 19 to the brake valve 18, while the exhaust from the latter passes through the pipes 21, 22 to the heater 5 in the dehydrator 1, the pipe 23, the silica gel in the dehydrator 2, and pipes 24, 25 to atmosphere. When the silica gel in the inoperative dehydrator 2 has been regenerated the settings of the valves 6, 7 are reversed to change the paths of flow of the compressed and exhaust air respectively through the two dehydrators 1, 2, the dehydrator 2 now becoming the operative one.

Title: Hydrodesulfurization of hydrocarbon feeds containing sulfur contaminants
IPC: C10G65/00
Filed: 1955-02-15
Abstract: Hydrocarbons are hydro-desulphurized and a portion of the products are again hydro-desulphurized.  The desulphurization may be carried out at a temperature of 500-800 DEG  F., a pressure of 50-1000 p.s.i. and a feed rate of 0.5-8 v/v/hr., depending on the particular hydrocarbon fraction being treated; catalysts specified are cobalt and molybdenum oxides, or cobalt molybdate, and nickel and tungsten sulphides and these catalysts may be supported on alumina.  Hydrogen or a mixture of gases containing hydrogen may be used for the hydro-desulphurization.  Hydrocarbon products, e.g. boiling within the range 400-1050 DEG  F. from the coking of residual fuels, e.g. a blend of naphtha and gas oil, may be treated.  The hydro-sulphurization of products from a heavy residual fuel, either with recycle of the higher boiling constituents or with their further treatment in a second desulphurization zone, is described.  The higher boiling constituents may be mixed with a hydrocarbon boiling in the motor fuel or heating oil ranges before the second desulphurization. Alternatively, the hydrocarbons from the coking operation may first be separated into a heavy gas oil fraction and a lower boiling fraction, the lower boiling fraction being blended with the desulphurized heavy gas oil before a second desulphurization, and the heavy gas oil separated therefrom recycled to the initial desulphurization zone.

IPC: C08L21/00
Filed: 1952-03-05
Abstract: Rubber-asphalt compositions for road surfacings and joints, roofing paints and papers, undercoatings for cars and trucks, and floor tiles are obtained by mixing with asphalt a free-flowing powder containing 10-50 per cent of unvulcanized rubber and 90-50 per cent of a carrier, e.g. barytes, perlite, fly ash, ground quartz, carbon black, soapstone or limestone, obtained by co-precipitating the unvulcanized rubber and the carrier from aqueous suspension and removing water from the precipitate, and, if necessary, comminuting.  According to an example, a road building component of composition 47 per cent asphalt, 47 per cent barytes and 6 per cent rubber is made by mixing an aqueous slurry of barytes with 30 per cent GR-S latex, coagulating by adding 0,5 per cent aluminium sulphate solution, filtering off the precipitate and drying it to 25-30 per cent water content, extruding the partly dried product as rods, drying the rods to less than 0,5 per cent water content, pulverizing, and mixing the powder so produced with powdered asphalt.

[Class 80 (ii)] A hub gear for cycles comprises a casing 3 integral with a chain sprocket 4 which is connected through two chains of pawls with a driven part 6 screwed on the hub 1. One set of pawls 60a is adapted to engage with an internal ratchet 17 on a ring 9 screwed to the part 6 and the other 60 with a similar ratchet on a ring 24 screwed into the casing. The pawls are pivoted at 59 to links 58, two sets of which are pivoted to an intermediate annulus 55 through pins 56. The annulus works on a ball race on a ring 31 movable on an eccentric 29 on a shaft 2 formed with a groove in which engages a lug 52, Fig. 9, on a guide member 48 bearing against a rack 39. A pivot pin 33 in the ring 31 projects into a groove 27 in a plate 26 having notches 35, Fig. 3, adapted to receive lugs 37 on a disc 38. Teeth on the disc 38, which is mounted on the shaft 2, are engaged by the rack, movement of which therefore shifts the annulus 55 in an up or down direction. In operation, the annulus 55 is driven by the casing 3 by that pawl 60 which has the lowest angular velocity, i.e. the topmost one in Fig. 4, the pawls engaging in succession with the ratchet 24. Similarly the annulus drives the part 6 by the pawl with highest velocity, i.e. the one at the bottom of the Figure. Progressive changes of gear ratio are obtained by moving the rack by means of any suitable control. In a modified form the links 58 are dispensed with and the connection of the pawls with the annulus 55 comprises shoes 66, Fig. 14, sliding in grooves 68 on each face of the annulus.
