Abstract

345,296. Indicating and recording speed. FAY, M. A., 1, Rue Picot, Paris. Dec. 16, 1929, No. 38485. Convention date, Dec. 15, 1928. [Class 106 (iv).] The spindle X is operated through fluid pressure means to be rotated through an angle which is a measure of the speed and has secured to it two discs D and E, one D carrying a lens H co-operating with a light source L and arcuate slot O to make a record on a clock-driven film F, and the other E having an arcuate slot K co-operating with the light source L and arcuate slot O<1> to vary the selenium resistance R and thus produce an indication in the ammeter I which is a measure of the speed. When used on an aeroplane approach of its speed to some predeterminded speed such as the stalling speed is signalled to the pilot by the pointer of the ammeter making contact with the adjustable sliding contact J to actuate the relay P, Q and thus the sound alarm T.
