Filed:

Oct 29, 1974

Appl. No.:

5/518713

Inventors:

Robert G. Parks - Mission Viejo CA
Howard E. Brewer - Santa Ana CA

Assignee:

California Computer Products, Inc. - Anaheim CA

International Classification:

G03B 4100
G03B 1900

US Classification:

354 4

Abstract:

The specification discloses a cathode ray lighthead for an electromechanical plotter. The head is adapted to be mounted upon the carriage of an X-Y Plotter in lieu of a conventional stylus. Plotting is effected on a photographic film through a combination of motions which include sweeping the beam in addition to mechanically moving the carriage. The system will produce both straight and curved lines of various widths, as well as symbols having any desired orientation.

Abstract:

Apparatus for determining weight of a container moving along a path past a weighing zone with radioactive source and detector mounted on opposite sides of the path for directing a radiation beam through the container passing through the weighing zone. Counters for counting radiation detector output pulses and reference timing pulses, with position sensors providing a gating for the counters so as to count when a container is moving past the radiation beam. The quotient of the two counts provides a measure of weight of a container.
