Title: A method of pouring predetermined amounts of liquid by measured volume
Inventor: HIBBARD WILLIAM DANIEL
IPC: B22D39/06
Filed: 1968-07-23
Abstract: 1,223,010. Discharging liquids by gaseous pressure. MODERN EQUIPMENT CO. July 23, 1968, No.35064/68. Heading F1R. Apparatus for discharging predetermined volumes of molten metal into a mould, comprises a reservoir 10 with an intake spout 15 and a discharge spout 16, a float 25 connected to an electrical circuit sensing the level of liquid in spout 16 and controlling the supply and venting of air or gas under pressure to a chamber 13 to start and stop the discharge of liquid over lip 20 of spout 16. With the control circuit shown, the liquid in spout 16 is first maintained at a set level below lip 20 determined by a signal from low level signal generator 30, float 25 producing a signal from generator 27 which with the signal from generator 30 is fed to amplifiers 28 and 32 and a converter 33 controlling a supply valve 34 and vent valve 35. When discharge is required, circuit 39 is energized to generate a signal which operates switch 29 to change from low level signal 30 to a signal 31 which causes the circuit to maintain a liquid level in spout 16 above lip 20, the height above lip 20 being adjustable to adjust the flowrate. A generator 40 produces a signal to cause an abrupt increase in pressure in chamber 13 to start the discharge. When the liquid rises above the level of lip 20, the signal from float circuit 27 rises above a reference signal from generator 42, which corresponds to the level of lip 20, and, through a voltage-to-frequency converter 43 actuates a counter 44. The counter records the volume discharged from the reservoir, and, when a predetermined volume is reached, operates switch 29 to return to low level signal 30. This causes the vent valve 35 to be opened to stop the discharge, an abrupt stoppage being provided by an error amplifier which detects the difference between low level signal 30 and the level recorded by float circuit 27. Amplifier 45 has a faster response than amplifier 28 and effects a rapid opening of vent valve 35. The vent valve 35 may comprise two valves, one of larger capacity than the other, the larger valve opening at a higher pressure than the other to provide a rapid halt to the discharge. Details of the circuit elements are given, Fig.4 (not shown).
