AbstractThe principles of thermionic refrigeration are explained. The simplest device is composed of two metal plates separated by a vacuum gap. This device is efficient at room temperature only for plates with small work functions (eø <0.3 eV).

Environmental ranking of refrigerants is of need in many instances. The aim is to assess the relative environmental hazard posed by 40 refrigerants, including those used in the past, those presently used, and some proposed substitutes. Ranking is based upon ozone depletion potential, global warming potential, and atmospheric lifetime and is achieved by

Journal of the American Medical Association, 1946
In war, problems of shock and trauma attain even more than their usual importance. A more general understanding of the newer ideas and methods may sometimes improve therapeutic results. In 1939 Allen1proposed the theory of a dual mechanism in shock.

Refrigeration for Photomultipliers
Applied Optics, 1966A closed-cycle mechanical refrigeration system has been adapted to cool photomultipliers automatically. Temperature is adjustable between +50 degrees and -55 degrees C and is stable to within +/-0.30 degrees C. An important feature of the design is the flexible connection to the cold box which allows extensive freedom of motion; this freedom is ...
