## Abstract This paper discusses a method of reducing heat losses from laboratory fractionating columns. A differential thermocouple in the lagging detects radial heat flow and controls the current passing through an electrical heater winding in the lagging, by means of a galvanometer, lamp and pho

Abstract
A still head which will deliver a constant weight or a constant volume of distillate has been developed. There are no moving parts in the still head itself, the reflux is continuous during operation, and the device may be made in glass or metal. It is particularly suitable for use on high efficiency laboratory columns where the distillation rate is small and automatic control is required.

This paper is devoted to the analysis of aircraft dynamics during take-off in the presence of windshear. We formulate the takeoff problem as a difIerentia1 game against nature. Here, the first player is the relative angle of attack of the aircraft (considered as the control variable), and the second
