Abstract
485,528. Depositing metals by electric discharge. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 8, 1937, No. 27401. Convention date, May 29. Addition to 439,774, [Group XL]. [Class 41] [Also in Group XL] In light-sensitive devices of the type described in the parent Specification, the additional step of first coating the selenium with a metal such as cadmium, by sputtering, is commenced in an atmosphere containing water vapour and completed in a dry atmosphere. The cell is placed in a holder 26 which is adapted to be moved by means of a magnet 34 from outside the bell jar 12, so that it comes underneath the cadmium electrode 33 or platinum electrode 32. The plate 20 acts as a partition to prevent sputtered deposits from one cathode being deposited on the other. The bell jar is evacuated and argon at a pressure of about 240 microns is introduced and the sputtering on of the cadmium layer in one-second flashes separated by twenty-second intervals is commenced. After one to five flashes liquid air is poured into the re-entrant bulb 14 causing water vapour inside the bell jar to condense. When the cadmium layer permits 30 per cent of the incident light to pass, the platinum layer is sputtered on for about three-fifths the length of time of the sputtering of the cadmium.
