Abstract: 9956. Draper, T. T., and Ryley, W. April 30. Filtering metallic solutions.-Relates to a process and apparatus for extracting the liquid obtained by the treatment of metalliferous slime, pulp, or sand with solvents, particularly a cyanide solvent. The material is delivered from a hopper A<1> to an endless travelling belt A, formed of porous material, and passing around two drums B, B' and rollers C. The edges of the belt may be turned up or strengthened, and while passing over the drum B the two edges are covered by two compression belts F passing around pulleys F <1>. While passing over the drum B<1>, the whole belt is covered by a washing-blanket F<2> travelling around pulleys F<3>. The peripheries of the drums are formed as a number of independent closed chambers b, each with an angular lower section y. These chambers are perforated on their outer surface, and are each connected by a radial pipe b<1> with an annular chamber b<2> at one end of the axle B<2>. The annulus is provided with a cut-off valve, whereby only the chambers b which are at that moment covered by the belt are connected with an exhaust pump. The liquid drawn into the chambers b by the pump is discharged, as the drum rotates, into the collecting-dish E. To weaken the solution, the material on the band is washed by the spray G. While passing over the drum B', the material is further washed, the water from the sprays G<1> passing through the blanket. The drum B<1> is formed similarly to the drums B, and the liquid similarly connected. The residual slime &c. is discharged, and may be carried by a belt H to a second mixing-apparatus, and afterwards passed a second time over the drums. Any number of drums may be used in series. In a modified form, the vacuum chambers are made of a segmental section to lie close together so as to form an endless belt passing around plain drums.

Granted: 1902-03-20
Abstract: 7845. Foulis, W. April 16. Starting and stopping -Relates to a charging apparatus for gas and other retorts, in which the charging scoop is supplied with coal &c. from a feeding-drum or a measuring-chamber. Fluid pressure is admitted by a valve 10 to a motor which operates this feeding drum. The valve 10 is forced inwards by a rod 12, which is pressed by a disc 13 to any desired amount by means of the sleeve 15, a bevel pinion 19, a bevel-wheel 20, and a vertical shaft 21, rotated by a hand-wheel 22. The fluid is admitted by the valve 10 through the passage 9* to the valve box 11 of the motor. The motor shaft then rotates, and in so doing the sleeve 15 is rotated within the bush 17, which is prevented from rotating in its bearing. The sleeve, therefore, by screwing in the bush, slides rearwards on the shaft, thereby removing the pressure of the disc 13 from the rod 12, and allowing the valve 10 to close under the pressure of the spring 14, and thus stop the motor. The distance to which the valve can be moved is adjusted by the ecrew 25.
