Abstract
750,787. Recording-apparatus. LEKSELL, L. Dec. 6, 1954 [Dec. 7, 1953], No. 35273/54. Drawings to Specification. Class 106 (4). A temporary record is made of a vehicle's speed on an endless detachable magnetic strip or tape on which are recorded electricallygenerated pulses at even intervals by a magnetic recording head, either the tape or the head being moved in accordance with the vehicle speed, a magnetic erasing head being provided to erase the records at a distance on the tape from the head which corresponds to the travel distance the speed over which it is desired to record.
