a telegraphic apparatus which records a
message on a moving
slip of paper moistened with a
solution. The chemical composition of the paper is altered on the passage of the current through a stylus.
a
type of recorder, such as those used in
telegraph equipment, consisting of a metallic
wire resting upon a moving, chemically treated
tape. Electric current passes through the
wire onto the
tape causing discoloration of the
tape with the
message being recorded as long and
short lines.
n. a device which records the
output of an
electronic piece of
equipment onto paper, such as that used on a
ship for finding the depth of water. The paper is treated with a chemical and is acted upon by a stylus which has a current flowing through it. The chemical composition of the paper remains unaltered until touched by the current flowing through the stylus at which
point a dark
line or dot appears. The stylus moves side to side
tracking the
output of the
equipment while the paper moves under it.
