摘要:
Experimental evidence in support of Van Lear's theory concerning the Brownian error of the resonance radiometer is given with photographic records showing the character of the baseline unsteadiness. A comparison between critically damped galvanometer systems and the resonance radiometer from an experimental point of view is offered.

摘要:
Platinum, boron, molybdenum, quartz and other substances have been evaporated in vacuum from a crucible heated by bombardment with electrons at 4000 volts from a tungsten filament. A small pure graphite crucible was heated to its melting point about 3500°C by 100 milliamperes of electron current. Most elements will alloy with a tantalum or molybdenum crucible so a graphite cup is usually preferable. Low melting point substances which would easily alloy with a tungsten filament can be readily handled by this method, which has been used in the preparation of x‐ray target surfaces, small mirrors and absorbing films.

摘要:
An osmometer is described which makes use of an optical lever for measuring rapid changes in volume of a solution in osmosis, and which is capable of being read at a distance and of magnifying the readings.
