Title: Improvements in or relating to the classification of materials by elutriation
IPC: B04C11/00
Filed: 1929-09-19
Abstract: 340,027. Classifying powdered materials &c. ANDREWS, L., 11, Southampton Row, London. Sept. 19, 1929, No. 28454. [Classes 23 and 82 (ii).] Classification of sand, powdered material &c. is effected by subjecting liquid containing the material to the combined action of centrifugal force and of gravity in a classifier having free outlets at top and bottom, the rate of discharge being controlled by siphonic or suction action at the top outlet. Liquid to be treated is introduced tangentially at e into the classifier between the top and bottom outlets, the heavier particles striking the walls a and falling down sloping walls a<1> to an outlet d. Liquid carrying finer material in suspension passes into an annular space h between cones f, g in the upper portion of the classifier, any intermediates passing through the space h and being discharged to join the heavies at the bottom of the classifier while the fines pass through perforations f <2> in the cone f and are discharged at b, the upward flow being produced and controlled by a siphon pipe c, the effective length of which may be varied by varying the height of liquid in a chamber u surrounding its lower end. The fluidity of the heavy particles and consequently their rate of discharge are controlled by a supply of liquid, e.g. water, through a pipe o to a vessel k from which it is discharged circumferentially through an outlet k<1> between the vessel k and an adjustable plate k<2>. This flow of liquid is normally directed upwardly owing to the siphonic action but in the event of a considerable accumulation of heavy particles in the space m it is diverted downwards and the rate of discharge is increased. In a modification, Fig. 2, a second siphon pipe 3 is provided, each of the pipes c, 3 having an air inlet valve 4, 5 to control the rate of discharge. An auxiliary siphon pipe 6, connected to the main pipe c, carries a barometric device 7 by which the air valves 4, 5 are automatically controlled and the density of the discharge through the main pipe c is rendered practically constant.

Title: Improvements in the treatment of sulphide and oxidized ores
IPC: C22B1/08
Filed: 1920-10-08
Abstract: Complex ores or their products are roasted with an alkali chloride at about 400 DEG  C. or lower with access of air so as to selectively chloridize the lead and silver, and the product is then leached with hot alkali chloride solution to dissolve the lead and silver, and afterwards, if desired, with a solution of sodium thiosulphate to extract the silver.  The leaching solution is treated with metallic zinc, galvanized iron, aluminium or the like to obtain the lead and silver, and the deposited metal may be compressed under water to avoid oxidation, and is finally melted down, or the metals may be obtained from the solution electrolytically.  The residue from the leaching is treated by the "acid-oil froth process" to obtain a zinc sulphide concentrate.  The Specification as open to inspection under Sect. 91 (3) (a) describes an alternative in which the ore is roasted at similar or higher temperatures so as to chloridize all the metals, and states that the second leaching solution may be treated to obtain the metals as above described, or may be first mixed with the alkali chloride solution, the mixture being treated as above described to obtain the metals.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1519823 Cathode-ray-tube displays COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 8 July 1975 [8 July 1974] 28668/75 Heading H4T The invention is concerned with a data-processor controlled cathode-ray tube image display system in which an operator-manipulated device, such as a "rolling-ball", designates, on the tube screen, an element of a displayed image and causes the X-Y co-ordinates of such element to be stored in the processor. As shown in Fig. 1, a dataprocessor 1 supplies digital data defining image elements via a transfer member 10 to a refresh store 20 the data being indexed by addresses in the data processor and such addresses being set up in an address counter 21. The output of store 20 is fed to a vector generator 22 via an input stage 27 which is supplied with clock pulses and acts as a binary frequency multiplier to provide incremental #X, #Y co-ordinate information to respective addersubtractors 23, 24 the outputs of which are supplied via digital-to-analogue converters 25, 26 and respective deflection amplifiers (not shown) to the horizontal and vertical deflection plates 31, 32 of the cathode-ray display tube 30. In operation, a "rolling ball" type generator is moved across the tube screen to a desired element and supplies the X-Y co-ordinates of such motion, in digital form, to respective co-ordinate stores, 43,44. The outputs of the latter stores are supplied, firstly, to a marker generator 45 producing signals which cause the display of a marker symbol superimposed on the desired element and secondly to respective comparators 41, 42 having as second inputs a respective succession of the X-Y co-ordinates of the elements of all images derived from the adder-subtractors 23, 24. On coincidence of the two inputs each comparator supplies an output signal to an AND gate 46 which may be conditioned by a signal from an operator controlled key 47 to transmit a signal to the load control input 49 of a register 48. The address of the marked element from address counter 21 is then recorded in register 48 and transmitted to the data-processor 1 via transfer member 10. In a second embodiment the vector generator 22 supplies the image element co-ordinates in analogue form and the "rolling-ball" device is also of the analogue signal producing suitable analogueto-digital converters being employed to provide the digital signal inputs to the comparators 41, 42 (Fig. 2, not shown).
