Abstract

1519954 Measuring velocity electrically NATIONAL RESEARCH DEVELOPMENT CORP 26 June 1975 [26 June 1974] 05470/78 Divided out of 1519953 Heading G1N The Specification repeats portions of the description in Specification 1519953, but the claims relate to apparatus for generating a velocity signal representative of the rate of change of an electrical capacity. In the arrangement shown, a battery 58 charges a capacitor C 2 through a resistor 59, the capacity of C 2 varying with the movement of a conductor (26), Fig. 4a (not shown). The voltage # across the resistor 59 provides a velocity signal representing dC 2 /d t
