Title: Improvements in and relating to the operation of jig washers
Inventor: CHAPMAN WILLIAM RONALD
IPC: B03B5/10
Filed: 1955-04-13
Abstract: The invention relates to the operation and stratification of materials of different specific gravities in a jig washer comprising a trough in which the strata are formed by settling upon the cessation of intermittent upward currents of a liquid medium, and consists in adding to the liquid medium five heavy solids to form a uniform suspension with an effective density (e.g. between 1.1 and 1.6) less than that of the lighter material to be separated, but such that the rate of settling of the lighter material is reduced to a greater extent than that of the heavier material.  Some or all of the fine heavy solids may consist of tailings from a froth flotation plant, the underflow from a slurry screen, or crushed rock or shale, and before being added to the jig washer they may be passed through a cyclone classifier to remove the finest particles.

[Class 100 (iv)] [Also in Group XIX] A calculating-machine has a front-feed platen for supporting a record sheet, mechanism for moving the platen from open-throat to closed-throat position and vice versa, and arrangements for coupling a power drive to the said moving mechanism so that the platen may be positively driven from one position to the other and vice versa. In the embodiment described, the platen is moved to the openthroat position when a key provided for this purpose is depressed. The next depression of the key causes the platen to return to closed or printing position. The platen is moved to closed position (if open) when any numeral key is operated or when certain control keys are depressed or when the machine functions initiated by these control keys are started instead by cams on the paper carriage. The platen is moved to open-throat position near the end of each machine operation unless this movement is inhibited by cams on the carriage. The embodiment described is a calculating- machine as disclosed in Specification 631 379.
