Abstract

188,352. Peet, W. L. Feb. 23, 1922. Clinometers.- A clinometer for aircraft comprises a dial board b with graduations of different colours, to which is secured by V-clips c an annular tube a containing liquid and an air bubble d, the tube and the dial being coated with a self-luminous compound to facilitate reading at night. Specifications 24415/97, 25125/97 and 126,860 are referred to.
