Abstract
527,737. Recording-apparatus. DOMIN, P. A. April 17, 1939, No. 11639. [Class 106 (iv)] [Also in Group XXXVIII] In a recording device for echo-sounders, a waxed strip a runs over a drum b which is rotated synchronously with the echo soundings and carries a helical recording edge c. The arrival of the echo causes the release (electrically) of a member d which is then pressed by a spring on to the recording edge so marking the recording strip at a point g whose distance from a zero line determines the depth sounded. In a modification, the recording edge has the form of an Archimedean spiral situated on a revolving disc, the member d now lying along a radius. Instead of the above arrangement, the recording edge may be made to press down upon the wax paper. The member d may be replaced by electrical contacts and a spark made to pass between one of these and the recording edge when the echo is received. Or again, the recording edge may be made to conduct heat which melts the wax when contact is made.
