Title: Means for regulating the addition of fine solids to washed small coal
IPC: B03B5/24
Filed: 1950-08-10
Abstract: 697,176. Mixing appliarsces; washing granular materials. NATIONAL COAL BOARD, and CHAPMAN, W. R. Aug. 9, 1951 [Aug. 10, 1950], No. 19948/50. Class 82(ii) and 86 In coal preparation plant of the kind wherein raw coal is led into a cleaning device in which the coal is cleaned and separated from refuse and in which the fine solids or a part thereof which accumulate in the cleaning fluid are led after removal of excess fluid to form an admixture with the cleaned coal, means are provided for automatically varying or interrupting the flow of the fine solids which are being fed to the cleaned coal, said means being responsive to variations in the rate of flow - of the raw or cleaned coal. In the embodiment of Fig. 2, raw coal is supplied to' a 'wash box 20 wherein an element 18 rises and falls according to the rate of supply of coal, such motion being transmitted' to a valve 25 which is thereby opened wider as the rate of supply of coal increases and. which admits compressed air from the reservoir 4 to the cylinder 19. A bleed cock 23 is coupled to the element 18 and operates together with the valve 25 so that a piston 19A within the cylinder 19 is displaced against a restoring spring 24 proportionately to the rate of supply of coal.to the wash box. The fine solids are removed from the wash box at a substantially constant rate and after dewatering are fed on to a conveyer 14 which discharges on to a flap valve 13 which is coupled to the piston 19A. The flap valve 13 is deflected by the piston 19A so as to direct the discharge of fine solids on to either the shoot 15A or 16A or intermediately between the shoots so that the amount of fine solid passing down the shoot 16 A is proportional to the rate at which coal is supplied to the wash box. The shoot 16A discharges the fine solids on to a mixer-loader 16 for admixture with dewatered cleaned coal which is transported from the wash box by a conveyer 17 and is discharged down the shoot 16B. A time delay is preferably inserted into the system, to compensate for the time that the cleaned coal is on the conveyer 17 and to absorb any slight time lag in the response of the element 18 to the rate of supply of raw coal to the wash box. In an alternative embodiment using a Baum type wash box the change of the amplitude of water pulsations according to the presence or absence of coal in the wash box is utilized to control means to permit or interrupt the supply of fine solid to the mixer loader. In another embodiment the control means includes a plate which is deflected by an amount depending upon the rate of flow of raw or cleaned coal. The invention is also applicable to dry cleaning systems in which the coal is cleaned by pneumatic methods.

A track lifting apparatus with provision for measuring the height to which the track has been lifted consists essentially of a first groundengaging member 3 to which the lifting power is applied and a second ground-engaging member 27<SP>1</SP> which merely rests on the ground, the second member carrying a height indicator 11 with a rail-engaging portion 12 vertically movable with respect to the ground to meter the change in height of the rail. The indicator 11 consists of a graduated sleeve 11<SP>1</SP> which is slidable on the stem 16 of the second groundengaging member and itself carries a slidable annular cursor 15. The latter is guided by pin-and-slot means (not shown) and urged upwardly by spring 16 to bring the pin to the end of the slot with the cursor at the zero of the scale. When lifting force is applied by operation of valve 20 to introduce pressure fluid into pipe 19 and thereby tend to depress the piston 2 which carries the first ground-engaging means 3, an electromagnet 17 is energized to hold the cursor 15 at a fixed level, the graduated sleeve 11<SP>1</SP> rising with the rail relative to the cursor as the track-lifting members 31 carried by the frame 5 are raised by the pressure applied to the piston 2.

Abstract: 499,592. Dough - dividing machines. CHRISTIANSEN, E., and ERICSSON, C. O. July 22, 1937, No. 20276. [Class 87 (ii)] A machine for depositing measured quantities of dough &c. comprises a deposit drum 2 having a number of chambers 1 at rightangles to the axis, said drum being intermittently rotated through 90‹ and the feed into the chambers and ejection therefrom taking place alternately after each movement, means coacting with a lateral member 3 carried by pistons 4 in the chambers for adjustably limiting their movement in the chambers, and separate means coacting with the member 3 for ejecting the material from the chambers. The drum 2 is journalled in the machine frame 18 and the pistons 4 are all connected to the member 3 which slides in slots 20 in the drum. The end of the member 3 carries a disc 6 having projections 5 which co-operate with a cam track 8 on a member 7 to adjust the position of the pistons and thus regulate the quantity of dough in the chambers 1. To vary this quantity, the member 7 is pivoted at 12 and has teeth 13 which are operated by a pinion 14 and shaft 15 to adjust the position of the track 8. The projections 5 are held against the track 8 by a spring pressed arm 9. The pistons are moved into the ejecting position by a slide 21 which has an opening 23 surrounding the member 3 and flat portions 24, 39 for operating the member. The slide 21 is operated by a cam 22 and the drum 2 is rotated bv a Geneva mechanism 35 as described in Specification 499,594. The chambers 1 are filled with dough when in the horizontal position by the plunger 19, and discharge the dough on to a conveyer 38 when in the vertical position.

Title: Method and apparatus for measuring the oxygen content in gaseous mixtures
Inventor: HOWE WILLIAM THOMAS
IPC: G01N27/00
Filed: 1951-08-28
Abstract: Apparatus for determining the quantity of oxygen in a gaseous mixture comprises means for exposing a known quantity of the gas to phosphorus and mixing the resulting gases with a measured volume of water, thereby producing phosphoric acid solution whose concentration, which is a measure of the original oxygen content, can be determined by measuring the conductivity of the solution. In an intermittently-operating system (Fig. 1) the water is supplied at a constant head from a tank 3 through a hydrogen-ion exchange unit 7 where the hardness is corrected and through a conductivity cell 13 into a tank 1 containing sticks of phosphorous.  The gas mixture is drawn into the mixing tank 1 through branch pipe 17 via an asbestos filter 22, and bubble bottle 24 by a water aspirator 21.  The <PICT:0707914/III/1> <PICT:0707914/III/2> phosphoric acid solution flows out of tank 1 through a syphonoperated overflow pipe 10, through a second conductivity cell 131, and the conductivity of the two cells 13, 131 is compared in a bridge circuit whose unbalance current is indicative of the oxygen content of the gas mixture.  A combined mixing tank and conductivity cell for continuous measurement comprises a glass flask 38 (Fig. 4) in which a capillary tube 40 is centrally supported by two sintered glass discs 41, 42, the former acting as support for molten phosphorous. The flask 38 is enclosed in a water tank 44, fed from a constant head supply by inlet 45, the water reaching the inside of flask 38 by capillary inlet 46.  The gas mixture enters through tube 40 from a pipe 60, bubbles through the molten phosphorus on disc 41, and escapes through outlet 54 while the acid solution passes through aperture 53 into a conducting chamber containing electrodes 57, 58, another set of electrodes 571, 581 measuring the conductivity of the original water.
