Abstract

1536276 Vehicle speed alarms ICKNIELD INSTRUMENTS Ltd 5 Dec 1975 [6 Dec 1974] 52928/74 Heading G1N The output voltage of an A.C. or D.C. dynamoelectric generator 1 is connected, after rectification if necessary, to a comparator 4 to which a reference voltage 5 is supplied, the connection not including any component with electrical characteristics that can be varied in use. The comparator output operates a relay 7, optionally via a delay, when the vehicle speed exceeds the reference value.
