Title: Improvements in the treatment of coal and other minerals
Inventor: MOSS GERALD
IPC: B03D1/04
Filed: 1965-07-08
Abstract: 1,123,597. Flotation. ESSO RESEARCH & ENG. CO. 17 June, 1966 [8 July, 1965; 19 Jan., 1966], Nos. 29063/65 and 2540/66. Heading B2H. Powdered coal or another mineral e.g. bauxite, phosphate rock, fluorspar, iron, copper, lead or zinc ores, is mixed with water in a vessel 1 and metered by a pump 2 into a line 3, where it is mixed with a volatile organic liquid, e.g. pentane, liquid butane or propane, which may also contain a less volatile liquid e.g. fuel oil such as kerosene, gas oil, phenol extracts, or coal tar. The volatile organic liquid aqueous coal suspension may be agglomerated in the line 3 and/or on entry into a closed vessel containing an inert atmosphere (which may be the exhaust from a dieseldriven heat pump). Here it is heated as by a steam coil 20 from the heat pump. Alternatively the light liquid may be evaporated by pressure reduction. The coal agglomerates as a froth, is picked up by a scoop 6 and fed to a rotary screen 7, which has coarse and fine mesh regions 8, 9. Coal agglomerates are retained in the screen 7 and the water drains into the vessel, the ash sinking to the bottom. Evaporating organic liquid is condensed at 13 by cooling with a refrigerating coil 14 cooled by the heat pump. De-ashed and de-watered coal is delivered via the seal 11 and hood 12. The condensed organic liquid is fed by a line 15 to a pump 4 and recirculated, and fuel oil e.g. kerosene is metered by a pumped 19. The ash is drawn off and filtered at 17, the water being returned to the vessel 1. The screen may be replaced by a vacuum filter drum. Alcohol additives, e.g. cetyl alcohol may be used together with flotation reagents, viz. oleic acid, sodium carbonate, lime, sodium ethyl xanthate, sodium alkyl sulphates, sulphuric acid, dextrin, starch, terpineol and phenol.

[Class 146 (iii)] In a refillable pencil having a longitudinally movable, leadgripping point-section, and a lead-clamping member which, after the point has advanced, carrying the lead with it, holds the lead in advanced position while the point recedes, the movable point-section 8 and clamping-member 3 are both moved relative to the stem 1 by a cap 10, which first carries the point section 8 with it for a predetermined distance d, and then engages the rear end 11 of the lead-clamping member, so that the pointsection 8 first advances a distance d from the clamping-member, and the latter is then released from a clamping - sleeve 4, and the lead then falls and engages the bore 9 of the point section; when the cap 10 is released, the members 8 and 3 move back together under the action of springs 5, 7, until the member 3 is again clamped, when the point moves on alone over the clamped lead which projects from the bore an amount equal to the last movement minus the length of the bore 9. The point section 8 is secured to the cap 10 by a tube 6, the lower end of which is split into externally-screwed fingers 6<a>, so as to pass through slots in the clamping-sleeve 4. The point section 8 is cone-shaped on the inside so as to co-operate with the clamping-member 3 in gripping the lead. The member 3 is integral with a tube 2 forming a lead chamber. The distance d through which the lead is advanced may be adjusted by screwing the cap 10 on to or off the tube 6.

[Class 59] The pressure of a grinding bar on a roll is effected by a hand-operated single mechanical arrangement through means which act simultaneously and equally on at least two blocks arranged so as to apply a uniform pressure on the whole length of the bar. As shown the breast bar 1 is pressed evenly against the roller 2 by blocks 14 ... 17, and the blocks 14, 15 are connected by pivoted links 12<1>, 122 to a beam 12 whilst the blocks 16,17 are connected by pivoted links 13<1>, 13<2> to a beam 13. The beams 12, 13 have equal pressures applied to their central points by pivoted links 11<1>, 112 connected to the ends of a beam 11 to which a pressure is applied at its central position by a hand wheel 10 screwed to a rod 9 attached to the mill frame. In a modification the bar 1 is moved by opposed wedges which bear against the underside of a cross-member 3 and an opposed wedge block resting on the bar 1, the opposed wedges being connected together by a right and left-hand screw bolt operated by a worm and wormwheel.

Class 23 [Also in Group XXVI] In a centrifugal pump for use with liquids which are highly volatile or contain gases, gas or vapour is separated from the liquid about to enter the impeller 41 by means of a separator 24 located beneath the impeller and having an inlet at the bottom, a central outlet for gas or vapour at the top and a peripheral outlet at or near the top for the liquid, the drum having helical vanes 32 around its inner surface. Subsidiary vanes 34 are intercalated between the vanes 32; both sets of vanes increase in pitch towards the top of the drum 24 until they extend substantially axially at their upper ends. The separated liquid passes around a sharp edge 37 of the impeller shaft 15 into the impeller 41. The gases and vapours pass upwardly through the shaft 15 to a vent. The pump is submerged within a fuel tank and is carried by a cover plate 12 for an aperture in the bottom of the tank. The drive is transmitted from a horizontally disposed electric motor 22 by gearing 19, 20. In a modification, the motor is vertically disposed above the impeller, which is carried by the lower end of the motor spindle.' In this case, the gases and vapours pass through holes in the top wall of the drum to vent passage which surrounds the shaft and leads to a vent pipe or back into the fuel tank.

In that form of sliding-needle, single straightbar machine in which the needles are in the yarn taking position after each complete traverse of the cam-box, the usual stitch cam is replaced by two pivotally-mounted members 11, 12, having needle lowering faces 6, 7 which include an angle of less than 180 degrees facing the butt ends of the needles and of which that one lagging on a yarn guide 10 is the active one during any traverse, the opposite face of each member 11, 12 being formed as a ramp by contact with which needle butts pivot the leading member, against the action of a spring, down into inactive position, so that the needles pass over it without being retracted. Thus, the yarn guide may be fixed to the centre of the cam box and still always lead on the effective stitch cam surface. In the space between the faces 6, 7 may be provided a star-wheel 26 having teeth of a pitch equal to the needle pitch, but of two sizes, so that, as it is rotated during a traverse, it lifts some needles into inactivity. The starwheel is secured to a spindle 36, which can be moved in the direction of its axis between an active (full line) and an inactive (broken line) position of Fig. 5 being located in these positions by a spring-pressed ball 51<SP>1</SP>.

Title: Method of separating optical antipods from the racemate of 1-p-nitro-phenyl-2-amino-1-3-propandiol of threo form
Filed: 1949-11-23
Abstract: The d- and l-forms of #Y-1-p-nitrophenyl-2-aminopropane-1 : 3-diol are separated from the racemate by heating a concentrated solution thereof in methyl alcohol (preferably to boiling temperature), adding a concentrated solution of d-tartaric acid in methyl alcohol to obtain a precipitate of the d-tartrate of the l-base which is quickly formed, and separating such precipitate (advantageously after cooling) before precipitation of the d-tartrate of the d-base occurs. Preferably the proportions of base and acid are substantially equimolecular so that the whole of the base is converted to the acid tartrate.  The d-tartrate of the l-base may be recrystallized from water, and the free base may be obtained by the action of alkali. The d-tartrate of the d-base may be obtained from the methyl alcoholic mother liquor on prolonged standing.  Specifications 652,275 and 652,280 are referred to.
