Abstract

Improvements in apparatus for measuring distances by sonic or supersonic waves, characterized by comprising means that contain a control circuit to produce waves in response to closure thereof; means for transmitting sound waves in response to the production of electric waves; means to receive sonic waves and produce electric waves in response to them; an element in which the record is inscribed; a stylet and means to move it, in order to make the stylet repeatedly scroll through the element for the inscription; means for applying to the stylet the electric waves produced in response to the received sonic waves, in order to produce, in the element for the inscription, an indication or signal located in accordance with the position of the stylus at the moment of reception of the sonic waves ; a switch for closing the control circuit when the stylet passes a predetermined point, located in the path of its movement and, in addition, because the switch comprises two adjacent, rectilinear and fixed conductive segments, which extend along one step parallel to the movement of the stylus on the element for inscription, and a single brush mounted on the means of movement of the stylet and moving successively on said segments, to close the control circuit when the stylet passes through the predetermined point, and for excite the stylet in response to the reception of reflected sonic waves, during the passage of the stylus over the inscription or registration element.
