Abstract

520,926. Galvanometers; optical indicating- devices. ELLIS, F. C. Aug. 29, 1938, No. 22190/39. Divided out of 518,728, [Group XXXVI]. [Class 106 (iv)] [Also in Group XXXVI] In a suspension-type moving-coil galvanometer the path of light from the galvanometer lamp 35 to the coil mirror 24 includes an additional reflector 23 set obliquely to and movable about the axis of the collimating tube 18, whereby the luminous index can be raised or lowered with respect to the scale 25.
