Abstract: |
The holder consists of a dome-shaped metal frame whose center of curvature is located at the arc of the carbon electrodes. The top of the dome is made with flanged bars, so spaced that the flanges support the slides, with all slides equidistant from the arc. The dome and its supports fit within a standard evaporator unit and provide the means for obtaining a uniform coating of evaporated carbon on all slides. © 1965 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted. |
