An inexpensive manual microidentification system includes a carrier card having the workpiece to be engraved mounted thereon and providing a surface for recording the information engraved on the workpiece; and a simple, inexpensive microengraver formed from a scriber mounted on a ball and socket arrangement, and including a stylus for tracing a pattern to be engraved on a workpiece as well as an elongated spindle interconnecting the two and providing a large mechanical advantage to the motion of the stylus relative to that of the scriber. The carrier card is cantilever mounted adjacent to the scriber; this mounting technique, together with the resilient composition of the card, insures a controlled scribing pressure. The workpiece is held out of contact with the scriber by means of a finger pressing against the card and biased by a spring. A slide bar connected to the finger is actuated by the operator to oppose the spring force when engraving is to take place to thereby allow the workpiece to contact the scriber for engraving. Accurate registration of the workpiece and the scriber is insured by apertures formed in the carrier card which is positively located within the mounting. After engraving, the work piece is separated from the carrier card for use, and the card is filed for reference as a permanent record.

Microidentification system

Apparatus for reproducing characters from cathode ray tubes wherein a beam is deflected onto alpha/numeric characters occupying a selected area of a font. The beam is deflected by relatively high speed linear vertical strokes which are displaced horizontally by a slower speed stroke advance waveform and each scan is positioned relative to one of the selected areas. The vertical linear strokes of the beam are at a variable rate and the vertical strokes are terminated by time interval pulses at an amplitude corresponding to the area height of the font character. The rate of the strokes is determined by the time interval pulses which in turn are regulated by point size control selection means. A resultant two level output signal representative of the successive selected characters controls another cathode ray tube, the scanning of which is identical to that of the first cathode ray tube. The deflection of the beam in the second cathode ray tube is at a constant rate and the intervals of the strokes in the scanning of the second cathode ray tube are also controlled by the time interval pulses.
