Title: Process for the extraction of high-grade products from raw material containing pit coal or brown coal
IPC: C10L9/00
Filed: 1952-12-19
Abstract: In the process of the parent Specification, intensive admixture of the coal particles with oil in the presence of water is effected by subjecting the mixture to intensive turbulence whilst causing it to pass continuously under pressure through a zone defined by losely adjacent surfaces and ejecting it from such zone through a narrow opening into a region of lower pressure so that it undergoes a sudden pressure reduction.  Such treatment may be effected in a baffle-plate mill having one rotating and one stationary baffle plate and a centrifugal wheel between the plates rotating in a direction opposite to that of the rotating plate, or in a mill having two baffle plates rotating in opposite directions; in either case, an annulur slot being formed round the periphery of the plates.  Air may be forced into the pulp during treatment or steam may be introduced. Subsequent to this treatment but prior to separation and dewatering, coarse constituents may be removed by cyclone, hydraulic classifiers, flatstone cells, jigs or heavy liquid treatment.

[Class 82 (ii).] In a process for separating coal, ores, or other granular materials from refuse in which the separation is effected in a high density fluid comprising a suspension of a finely divided solid such as sand in a liquid such as water, the suspension being maintained by mechanical or hydraulic agitation, means are provided to prevent the accumulation in the system of fine coal, ore, &c. either present in the feed or produced by attrition in the separating tank. Coal is fed over a screen 2 to a separating tank 3 containing a suspension of sand in water of sufficient density to float the coal while allowing the refuse to sink to a refuse chamber 5 controlled by valves 4. Coal, mixed with fine coal and the suspension liquid, overflows to a vibrating screen 7 from which the clean coal is discharged at 9 while the refuse is discharged from the chamber 5 on to a vibrating screen 6 along which it passes to a discharge trough 8. The fine coal and suspension liquid passing through the screen 7 and the suspension liquid passing through the screen 6 are led by a pipe 10 to near the bottom of a vessel 11, in which the water and fine coal tend to rise and overflow into a tank 16 while a dense suspension of sand is withdrawn from the bottom by a pump 14 and returned to the separating tank 3. Some of the fine coal and water in the tank 16 is discharged at an overflow 20 or through valve spigots 21, the rate of discharge being controlled to prevent accumulation of fine coal in the system. Additional water is supplied at any point of the system by a valved pipe 22, the remaining water and fine coal in the tank 16 being recirculated by the pump 18 to the bottom of the tank 3 where it helps to maintain the suspension, and to the screen sprays. A plurality of vessels 11, tanks 16, sand pumps 14, and water pumps 18 may be employed. Specification 119,038, [Class 82 (ii), Washing granular &c.], is referred to.

Title: Improvements in or relating to rudder servo-motors for vehicles, in particular aircraft
IPC: G05D1/00
Filed: 1937-11-26
Abstract: 506,360. Fluid - pressure servomotors. SIEMENS APPARATE UND MASCHINENGES. Nov. 26, 1937, Nos. 32702 and 32703. Convention dates, Nov. 26. 1936 and Nov. 12, 1937. [Class 135] In a rudder servomotor more particularly for aircraft rudders in which the two ends 1, 2 can be placed in communication by means of a normally closed change-over valve 7 actuated by the same source of pressure as is supplied to the servomotor control valve 5, loss of fluid past the control valve 5 is prevented or is so far reduced that an adequate pressure of fluid for closing the change-over valve 7 is maintained in the system. The valve 7 may control a byepass 6 as shown or separate valves may control outlets additional to those formed by conduits 3, 4. The arrangement is such that in changing over from manual to automatic steering, the necessary pressure for closing the bye pass valve 7 is available even if the slide valve 5 has been left away from the neutral position. Moreover the change over may be effected without cutting off the pressure medium supply whilst if the latter fails, the valve 7 opens automatically to permit manual operation of the servomotor. As shown in Fig. 1, the valves 14, 16 are operatively connected so that the valve 16 closes before the valve 14 opens and opens after the valve 14 has closed. The valves 14, 16 may be operated electromagnetically, hydraulically, pneumatically or mechanically from a remote point such as the pilot's seat. The desired sequence of operation can also be effected when the valves< >are reversed in the position of rest from that shown i.e. the valve 16 is closed and the valve 14 open. Alternatively, the separate valves may be operated in the desired sequence from a single control. A throttle 13 in the pipe 8 connecting the valve 7, to the main supply pipe 17 permits pressure to be built up in the pipe 8 when the valve 14 cuts off the exhaust pipe 12 whilst preventing appreciable loss of medium when the valve 14 is open. The vave 7 is opened by a spring 9. In Fig. 2, the valve 14 is separate from the valve 16 which is formed as a piston 16 rigigly connected to the valve 7 which is also a piston. The valves 7, 16 are operated by it piston 19 under the control of the valve 14 and their movement is limited by stops 21, 22. The valve 16 does not open the connection between the conduits 10, 17 until the valve 7 has passed the conduit 4. In either modification a throttling point may be substituted for the valve 16 in the conduit 10. The cut off valves 14, 16 of serveral servomotors may be controlled from a remote point, or the two valves 14, 16 may serve more than one servomotor. Additional pistons corresponding to the number of servomotors may be provided on the rod 18 Fig. 2. Further the rotative positions of the valve 14 and throttle 13, Fig. 1, may be reversed.
