For greater safety the set [Note received 3 'May, 19501 screw (10) may be used to augment the clamping action of The apparatus described in the figures permits the rapid adjustment in height of a weight, such as a mercury bulb, through a distance of several feet. It can be left automatically clamped at any height and it is, furthermore, possible to make fme adjustment of the level of the mercury through a range of a few centimetres. The construction is illustrated by Figs. 1 and 2. A weight, in the present case a mercury bulb (l), is supported in a cradle (2) (steel TI - Mercury bulb lift JO - Journal of Scientific Instruments DO - 10.1088/0950-7671/29/2/407 DA - 1952-02-01 UR - https://www.deepdyve.com/lp/iop-publishing/mercury-bulb-lift-mrtRufAibO SP - 58 VL - 29 IS - 2 DP - DeepDyve ER -
