Abstract

538,066. Indicating-apparatus. STEVENSON, H. A. Feb. 7, 1940, No. 2344. [Class 106 (iv)] A pyrometer device comprises a casing 1 in which a pyrometer 3 is housed so that the scale 4 is viewed at the front wall of the casing, a light source 13 at the rear of the case, and a mirror 5 on the pointer axis of the pyrometer galvanometer from which a pencil of light from the source 13 is reflected on to a second mirror 19 at the rear and from thence to a magnified " light scale " at the front of the casing. Both the rear mirror and the source of light are adjustably mounted in the casing while the ight scale is divided into a lower ground glass part 10 on which an illuminated arrow appears and an upper graduated and illuminated part 8.
