Abstract

337,532. Feeney, W. P. Aug. 5, 1929, [Convention date]. Pulp, regulating flow and consistency of. - A stock regulator for paper-making machines &c. comprises an inlet chamber 2, an overflow chamber 3, an outlet chamber 4, a gate 12 the flow of stock over the upper edge of which is only restricted by the quantity of stock present, a float 8 which raises the gate to allow the stock to flow under the gate to the overflow chamber 3, and a trough 21 which conducts the stock. flowing over the gate to the outlet chamber. The chamber 2 is supplied, and the chambers 3 and. 4 are drained, by pipes 5, 6 and 7 respectively. The float 8 is adjustably mounted on an arm 10 pivoted at 11 and carrying the gate 12, which operates against flanges 17 - - 19 of an aperture 16, a balance weight 13 being adjustable along. an arm 14. The trough 21 which normally rests on a rod 22, is pivoted on a rod 23 and is raised substantially vertically when the paper-making machine is permanently or temporarily eliminated from the circuit. The device is sensitive to level and to density of the stock and eliminates stratification as there is always circulation in the supply chamber 2. The arm 10 is of aluminium or a light alloy, and ball bearings are used, to give sensitive control.
