Title: Improvements in or relating to apparatus for delivering measured quantities of liquids
IPC: G01F11/28
Filed: 1946-07-29
Abstract: 615,146. Delivering measured quantities of liquids. MACHINERY ENGINEERS & DESIGNERS, Ltd., ASKEY, A., and BURTON, E. W. July 29, 1946, No. 22524. [Class 106(v)] Apparatus for delivering measured quantities of liquids comprises a tank 1 fitted with electro-magnetically operated intake and discharge valves 4 and 5, the control circuits of which include the liquid in the tank, a fixed electrode 2, an adjustable electrode 3 and a return lead connected to the tank. Contact between the liquid and electrode 2 effects the closing of the intake valve so that the tank is refilled to a constant depth after each delivery. The opening of the discharge valves is effected by a push-button switch operating through a relay, and the level falls until the contact between the liquid and the electrode 3 is broken, the discharge valves then being closed and the intake valve opened automatically to refill the tank. The control circuits include a relay which short circuits the switch to maintain the discharge valves open during the emptying of the tank, means for rendering the switch ineffective during the filling of the tank, and means for preventing closing of the intake valve until the liquid contacts the fixed electrode. More than two discharge valves may be fitted and each valve may be associated with an independent control circuit and switch. The electrodes are fitted with plates 56 to increase the contact area, and the electrode 3 is adjustable by rack and pinion gearing operable by a handwheel 43 to vary the quantity measured. The handwheel carries an arm moving over a scale to indicate the quantity measured and is retained in any adjusted position by a spring-pressed pin engaging holes in the scale plate. The rack is coupled to a counterweight 54, see Fig. 4 (not shown). The depth to which the tank is refilled may be varied by altering the position of the electrode 2.
