Abstract: 1523603 Gyratory crushers, jaw crushers, impact mills, ball-and-ring mills, roller mills, comminuting coal KAMYR INC 4 Aug 1975 [8 Aug 1974] 32520/75 Heading B2A A comminuting system particularly for coal gasification comprises a chute 1 Fig. 1 a transmission device 2 which transfers coal from a low pressure liquid system to a high pressure liquid system in which the coal is fed to a dewatering separator 3, and thence to a centrifugal separator 4. The dewatered coal is crushed in a roller crusher 5, and metered into a pressurized ball-and-ring mill 6 which includes an integral cyclone separator 416 which returns insufficiently ground material to the mill. The coal is thence blown to a cyclone 7 by a fan 22. The cyclone 7 discharges into a fluidized bed gasifier 8a or a suspended particle gasifier 8b. Both being of known types. The centrifuge 4 comprises two concentric cones 38, 39 in a pressurized housing. The inner cone 39 is turned by shafts 211, 213 and has screw-form scraper plates 204. Surface water is thrown through the outer cone 38 (which is a screen) and the water is drained into a trap 215. The water level is monitored by a sensor 21 which controls a valve 19. The ball and ring mill 6 includes a stationary race 410 forced down on the balls 409 by springs 411. The force is adjusted by a mechanism 412, 414. Other coal crushers may replace the roller mill 5 e.g. a Bradford breaker, single roll crusher hammermill, ring crusher, cone crusher or jaw crusher. Water level in the chute 1 is controlled by a sensor 15 controlling a valve 13. Water level 111 in the dewaterer 3 Fig. 1, 100 Fig. 2, is controlled by a sensor 18 and a valve 16. Temperature in the pulverizer is controlled by valves 23, 25. Valve 25 permits cool gas to escape into the produced gas. Valve 23 permits hot gas to mix with recycled gas. A valve 24 controls the gas velocity in the system and thus the proper size classification in the pulverizer 6.  In the transmission device 2 coal enters via an inlet port 74 into a pocket or, as shown, two pockets 81 of a rotor 79, and is retained there by a screen 80 in the outlet port. As the rotor turns the coal is carried from the pocket through a port e.g. port 97 into conduits 71, 72 and thence into the inlet port 99 of the separator 100. The motor rotates within a liner 92 which includes four peripherally spaced ports 94....97 Fig. 4. Clearances due to wear are taken up by a handwheel 85, and pressures at the ends of the rotor are balanced by a pipe 89.

Abstract: 307,375. Johnson, J., Y., (I. G. Farben. industrie Akt.-Ges.). Dec. 5, 1927. Addition to 300,719. Synthetic caoutchouc.-Rubber is coagulated from emulsions of synthetic rubber or from mixtures thereof with natural latices, by means of enzymes having a proteolytic action. Suitable enzymes are papain, the secretes or extracts of pancreas, and the sap or juices from ficus or musa species, such as ficus carica, ficus rostrata, ficus bengaleusis and banana. Substances which enhance the activity of the enzymes, such as hydrocyanic acid or hydrogen sulphide, or saline mixtures possessing buffer properties, may be added. The rate of coagulation can be controlled by adjusting the pH of the emulsion. In an example rubber latex, freed from ammonia by dialysis, is mixed with synthetic rubber (prepared by emulsifying butadiene or its homologues by water and polymerizing the emulsion); disodium citrate is added to impart a slight acidity, .and then an aqueous solution of papain activated with hydrocyanic acid, whereupon the whole rub. ber is precipitated in a short time. Specification 300,719, [Class 70, Indiarubber &c.], is referred to.

Abstract: 521,054. Variable speed gear ; telemotors. OLIVER, A. V. Nov. 12, 1938, No. 32932. [Class 80 (ii)] [Also in Group XXIX] In a change-speed gear in which synchronisation of the dog clutch or gear about to be engaged is dependent upon and produced positively by the load applied to a pedal during its downward movement, the actual engagement being effected during upward movement of the pedal, both operations occurring with the mechanism disconnected from the engine, the operation of the gear change rod b and the rod a controlling the transmission clutch are effected hydraulically in the desired sequence by the progressive operation of a plurality of plungers. As the pedal c is depressed to move the plunger c<2> the plunger d moves to disengage the transmission clutch, the auxiliary plunger i then moves to effect gear disengagement, and plunger m then moves to admit pressure fluid behind the plunger h which moves to effect synchronisation between the selected gear and its mating member. On the return of the pedal the pressure on the rod b is reduced and the selected gear is positively engaged by a spring and further reduction of pressure on the rod a allows the clutch to be re-engaged by springs. A liquid reservoir s keeps the system filled and an air release valve u is provided. Instead of operating from a master cylinder c' a source of pressure supply provided with a reducing valve may be utilised. Specifications 459,556 and 484,816 are referred to.
