Abstract

1,187,026. Delivering measured quantities of liquid. J. F. EARDLEY Ltd. 28 June, 1967 [28 July, 1966; 24 Oct., 1966], Nos. 33893/66 and, 47542/66. Heading B8N. An apparatus for dispensing measured quantities of liquid comprises a dispensing unit 18 controlled by valve means 38, 40 which are remotely controlled by a valve 54, and detent means 78 for preventing operation of the valve means until a full measure of liquid has been dispensed from the unit. The detent means is in the form of a plunger 78 adapted to co-operate with a groove 86 in an actuator 68, associated with the remote control valve 54, the plunger being moved into engagement with the groove by the flow of liquid in a discharge pipe 30; a similar detent device is also provided in the delivery pipe 26 to the dispensing unit 18. As shown, a second dispensing unit 24 is provided so that as one fills, the other empties. In operation, upon depressing a push-button 56 on the valve 54, compressed air is fed via pipes 58, 60 to move a valve 64 to a position in which air can flow via a pipe 46, valve 40, pipe 48 to actuate the valve 38 so that air acting on one side of a diaphragm in the unit 24 is exhausted, thereby allowing liquid to flow into the unit on the other side of the diaphragm via the pipe 26 and one-way valve 29. When the push-button is released, air flows via pipes 58, 42, valve 38 and pipe 34 into a chamber 20 of the unit 18 so as to dispense a measured quantity of liquid as the other unit is filling; simultaneously, the position of the valve 40 is, via a pipe 35, changedover in readiness for the apparatus to operate in the reverse manner. In modifications, instead of the valve 54 being operated by compressed air, it is solenoid actuated and the detent plungers incorporate magnets adapted to actuate reed switches (Figs. 2, 4, 6, not shown). The plungers may, when liquid flow ceases, return by gravity in order to open the switches or be returned by a spring; in the latter case the plungers may be positioned horizontally. Reference has been directed by the Comptroller to Specification 1,011,863.
