Title: Improvements in or relating to an apparatus for the transport of coal or other minerals from mines
IPC: B65G53/30
Filed: 1945-09-14
Abstract: 599,284. Lifting coal &c. to the surface by a liquid medium. CRAVEN. R. H. Sept. 14, 1945, No. 23711. [Class 102 (ii)] A system for transporting coal &c., from a mine to the surface out of contact with the atmosphere, comprises a closed gravity-operated system of pipes fed as shown, from a tank 1; Fig. 1; out of which brine or other liquid descends a pipe 19 to mixing chambers 15, 16 where the coal is introduced, and thence flows together with the coal, along a pipe 14 to a rising main 3 which delivers it to a trommel 4 at surface level above a reception tank 2 for the coal, the freed liquid being pumped thence to the tank 1, gravity traps for heavy material being provided in the horizontal run 14 of the pipes, all of which are lined with rubber &c. to protect them from abrasion and electrolytic action. The horizontal pipes may be large enough to permit the passage of a man and so provide an emergency exit. Coal crushed to suitable size is dropped alternately from hoppers 11, 12 past a valve 18, Fig. 2, into the mixing chamber, which may be formed from sections designed for easy transport through the mine, while the mixing chamber is empty of liquid when it has been filled, liquid from an intermediate tank 17 is run in. filling being completed by opening a valve leading from the pipe 19. Air in the spaces between the coal lumps is driven out into cylinders 20, 21 and there retained. When pressures within and outside the mixing chamber have been equalized, a valve 42 is lowered from its seat 45 and the chamber discharges along the pipe 14 to the riser 3. The coal having been discharged, liquid is ejected from the chamber in part by compressed air from one of the cylinders 20, 21 which delivers it to the tank 17, the remainder being withdrawn through a port 26A by a pump 28 which also receives coal dust removed from the atmospheric air by a cyclone separator 32 and feeds the whole to the riser 3. To assist the upward flow, air or concentrated brine &c. from a high level tank 36 may be fed to the bottom of the riser which may comprise a spiral providing an inclined path for the coal.

Title: Magnetic device
IPC: G11C19/06
Filed: 1958-07-23
Abstract: 878,156. Transfluxors. HUGHES AIRCRAFT CO. July 23, 1958 [Aug. 2, 1957], No. 23772/58. Class 40 (9). A stepping register uses transfluxors. The transfluxor of Fig. 1 is set to the " zero " state shown in Fig. 3 by a drive winding and is set to the " one " state by an input winding. The ''one'' state may be changed to a " prime " state using a prime winding and this change produces an output in the output winding, an output also being produced by the drive winding when the "prime" state is switched back to the " zero " state. The stepping register is shown in Fig. 4 where alternate transfluxors are set to " zero " over wires D1, D2, and are made " prime " over wires P1, P2. The output winding of one transfluxor is connected to the input winding of the next transfluxor and a " one " stage injected into the first transfluxor is stepped from left to right in response to successive prime and drive pulses. By using a storage circuit in the input output loops alternate prime and drive wires are not necessary. The speed at which a transfluxor may be switched is increased by winding a portion of the " prime " winding in opposition to the drive winding (see Fig. 7, not shown). The transfluxors may be made from thin magnetic films. Specification 874,373 is referred to.

Title: Improvements in or relating to processes for the production of graphite
Inventor: DAVIDSON HUGH WILSON
IPC: C04B35/524
Filed: 1956-08-07
Abstract: Substantially impermeable graphite used particularly for the manufacture of fuel support sleeves for nuclear reactors is produced by joining a dispersion of cellulose in which the fibrous structure of the cellulose is broken down in an aqueous medium, regenerating the cellulose from the dispersion, carbonizing the regenerated cellulose and graphitizing the carbon at 2500-3000 DEG  C. Cellulose, e.g. blotting paper or cotton wool, may be beaten or milled until substantially non-fibrous to the naked eye and dispersed in water, preferably being beaten or milled during dispersion formation, or be dispersed without such treatment in water containing a chemical dispersing-agent, e.g. zinc chloride. The cellulose may be regenerated from the dispersion by removal of supernatant water by filtration or centrifugation and drying of the cellulose at, say, 15-40 DEG  C.  When chemical dispersing agents are employed the chemical is washed out of the dispersion before removal of the water. The regenerated cellulose mass may be formed and machined preferably before carbonization instead of after final graphitization. Alternatively, the dispersion of cellulose, preferably that formed without the aid of a chemical dispersing agent, or the regenerated cellulose may be employed as a binder instead of, say, pitch for admixture with coke prior to extrusion or moulding, firing and graphitization to form a substantially impermeable graphite mass or graphite masses produced by known processes may be made impermeable by impregnation with a dispersion of cellulose followed by carbonization and graphitization thereof.

Abstract: 1305345 Detecting position INTERNATIONAL STANDARD ELECTRIC CORP 19 April 1971 [23 March 1970] 24509/71 Heading G4H [Also in Division H1] A photoelectric object location tube for locating the position in a field of view of an object, such as a star or a jet engine, distinguished from its background by colour or luminosity, comprises a photocathode the output of which is directed to an assembly of channel multipliers which are connected at each end in a polar or a cartesian co-ordinate system. When the co-ordinate system is cartesian, the channels 20 of the multiplier (shown as resistances in Fig. 7) are connected in rows and columns to respective resistances 22 and 21 as shown. When a particular channel corresponding in position to that of the image of a bright object on the photocathode receives an input from the photocathode the current through it increases and the potentials across its associated row and column resistances increase; these potentials may be monitored sequentially and used to feed a cathode ray tube display which indicates the position. The resistances 21 and 22 may each be connected through a threshold detector and amplifier to a clamp (Fig. 8, not shown) which allows noise fluctuations and background illumination to be eliminated, and the clamps are connected sequentially to the intensity control of a cathode ray tube under the control of pulses from generator 37, Fig. 9. The generator also triggers a sawtooth generator 49 and a counter 39. When the rows are being sampled, a step voltage is fed from coverter 42 through gate 45 to the vertical deflection and the sawtooth wave is connected through gate 47 to the horizontal deflection, so that the vertical position of any channel energized is indicated by a bright horizontal line on the tube, subsequently the columns are sampled and the horizontal position is similarly indicated by a vertical line. Instead of the same voltage being applied to all resistors 21 different voltages may be used (Fig. 10, not shown) so that it is possible to detect more than one target, and the resistances of the channels 20 may be different.
