Title: Improvements in or relating to coal treatment
IPC: B03B1/04
Filed: 1959-09-14
Abstract: Coal is treated by a method which comprises intimately mixing a dry or only surface-wet raw coal fraction containing fines and/or smalls with not more than 10% by weight of oil or other non-aqueous reagent, whereby the particles of such coal are rendered hydrophobic, mixing the thus-treated coal with water and charging it into a coal-treatment machine from which the coal is recovered.  The hydrophobication causes the fine particles to agglomerate, or to adhere to larger particles, when the mixing with water takes place. Preferably the mixing with oil is carried out at an elevated temperature which may be provided by direct steam.  The treatment can be improved by providing, before the actual washing process, a wet intermediate treatment of the pretreated coal in mixers, on wet screens or in a purification drum.  Examples are given of the treatment of fines of various compositions.

As described the direction changing arrangement is incorporated in a burrowing device of the type described in Specification 1392868. The guide member 54 is fixed in the housing 12 by a retainer 58 and is provided with a pair of grooves 60 (Fig. 4). The valve member 42 is provided with a middle stop in the form of a pair of keys 52 and with two end stops in the form of collars 48, 50. The valve member 42 is held in one or other of its operative positions by the guide member 54 being located between the middle stop 52 and one or other of the end stops 48, 50, the valve member 42 being prevented from rotating by a ball catch 62 (Fig. 5) engaging one of two recesses (not shown) formed in the valve member. The ball catch 62 can be released by moving an actuator pin 64 rearwardly 'by pulling on a cable secured to an extension 66 of the pin 64. The pin 64 is biassed forwardly by spring 68. In operation, to change the direction of travel, the pin 64 is moved rearwardly by pulling in the cable to release the ball catch 62, the valve member 42 is rotated (by manipulating the air hose) until the keys 52 are aligned with the grooves 60, the valve member 42 is then moved axially to its other operative position and is then rotated to lock it in this position, the ball catch 62 again engaging a recess in the valve member 42.

In an air traffic control system, a control officer sees aircraft on his ground radar and interrogates aircraft, which replies by giving its own position co-ordinates as determined by any known, e.g. hyperbolic, means. These co-ordinates are compared with those on radar and aircraft is thus identified. Any difference between radar co-ordinates and aircraft determined co-ordinates causes correction signal to be transmitted to aircraft to correct its instruments. Ground system also includes tracking system for interpolating aircraft position should aircraft position finding means break down. Comparison between radar co-ordinates and aircraft determined co-ordinates may be made on aircraft.

Filed: 1956-10-22
Abstract: 818,265. Screw-and-nut gearing. SPARK - LETS Ltd. Oct. 10, 1957 [Oct. 22, 1956], No. 32122/56. Class 80 (3). [Also in Group XXIX] An actuating device for an axially-movable valve spindle 18 of a single-beat lift valve 17 fitted in the outlet of a compressed gas container and held closed by gas pressure, comprises a pulley-like actuating member 37 rotatably held in a casing 27 by a cap 43, an actuated member 40 which is fitted with a stem 54, for abutting against the valve spindle, and has a squared end 51 slidably guided in splines 52 formed in the casing, and an intermediate member 38 coupled to the actuating member by a coarse screwthread and the actuated member bv a fine screw-thread of the same hand. A pin 47 which holds the stem 54 in place in the actuated member projects therefrom to form an abutment for shoulders 46 on the intermediate member to limit its rotational movement. In operation, when the pulley-like actuating member 37 is rotated by means of a pull cord fitted at 64 the friction of the coarse thread causes the intermediate member 38 to rotate and its fine thread moves the actuated member 40 axially with a large mechanical advantage to crack open the valve against gas pressure, continued rotation causes a shoulder 46 on the intermediate member to abut against the pin 47 of the actuated member and lock the two parts to. gether when the action of the coarse thread, with a lower mechanical advantage, rapidly, fully opens the valve against the reduced closing force of the gas. An indication that the actuating mechanism is set for operation is pro. vided by a coloured disc on the top face of the pulley which is visible through an aperture 78 in the housing cap, and the recess 63 in the actuating member which houses a ball on the end of the pull cord is so shaped that the pull cord is freed from the mechanism when it is actuated. A pin 44 in the actuating member co-operates with a stop in the actuating mechanism housing to limit its movement to one revolution. According to the Provisional Specification the differential actuating screw-threads may also be of opposite hand and also means may be provided for actuating the valve member directly.

Abstract: 990,993. Measuring electrically. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 19, 1961 [Sept. 19, 1960], No. 32129/60. Heading G1N. An electrical signal generator for producing a signal representing speed and direction of rotation comprises two stationary Hall plates 3, 3a, disposed radially of a shaft 2 and mutually displaced by a small angle x, and a U-shaped magnet 1 secured to shaft 2 so that when the latter rotates the flux from the magnet traverses the Hall plates to produce mutually overlapping flat-topped output pulses therefrom, the output pulses from one of the Hall plates being differentiated to produce peaked pulses of opposite sign at the beginning and end of each output pulse, while the output pulses from the other Hall plate control a gating circuit to allow one of the two peaked pulses to pass to indicating or controlling means, the sign of the pulse passed being indicative of the direction of rotation of the shaft. Preferably the output pulses of the one Hall plate are squared, as by a bi-stable flip-flop circuit, before being differentiated. Two or more magnets may be symmetrically mounted around the shaft; in this case, the angle x of displacement between the Hall plates is increased by the amount of the angular displacement between the magnets.
