A system is described in which the vapour pressure of a liquid He 4 bath is monitored by a capacitance gauge, the output of which is used to control the pumping rate of the vapour pump. The pressure is regulated to an accuracy of O. 1% or better over the range 3-1000 mm Hg and the system is usable c
## Abstract An electronic timing device is described, which is designed to operate a magneticallyβcontrolled reflux dividing head for stills using a total condenser. The timing unit is constructed of readily obtainable radio components and can be assembled by anyone with a good knowledge of electri
