Abstract

1500334 Raising liquids by vacuum O G ROBINSON and J R BOSWELL 6 Feb 1976 [18 Feb 1975] 6888/75 Heading F1R [Also in Division B 1 ] A receptacle 7 has a liquid inlet 9 provided with a screen 5 and a connection 8 to a vacuum pump, the connection 8 being closed by a float valve 4 when the level of liquid is at a given height. The pressure difference existing between the receptacle 7 and the connection 8 when the valve 4 is closed is applied across a diaphragm 3 connected to a switch 1 which operates a relay (10) to stop the motor driving the vacuum pump. The connection 8 includes a bacteriological filter which includes an air bleed to the pump (see Division B1).
