A component part number marking or engraving machine has a microprocessor controlled marking or engraving tool in which a range of part numbers, and the corresponding instructions for operating the tool are stored in memory. Upon calling up the appropriate instruction set a selected part number is automatically marked or engraved on a component. The present invention provides a fixture for receiving the component and has a plurality of sensors responsive to the physical dimensions of a range of components and disposed so as to uniquely identify each type of component in the range. Each valid combination of sensors signals is indexed against the appropriate part number and is used to retrieve the corresponding engraver operating instructions from memory.

A magnetic-electronic linear measurement gage for measuring workpiece miter lengths for picture and window frames and the like includes a gage bed on which a workpiece may be removably mounted, a stop body slidably mounted on the gage bed having a stop which may butt against a workpiece mitered end, and length and width scales and scanning units associated with the gage and the stop body generating output signals in response to the scanning of the scales. The output signals are received and converted by a CPU to generate a linear measure output signal which may be inputted to a digital LED display for visually displaying the linear measure corresponding to the workpiece length so measured.

A production planning system for use in providing color-separated films to a litho platemaker. The system utilizes a programmed computer for gathering and storing information relative to various images of a particular production job. A computer/digital table/rotating arm structure allows for calculation of scaling and angling factors of the original image transparency relative to the size and orientation of the image within the final layout.

This invention relates to a measuring device for a coordinate of a figure in which values of coordinate positions of a plurality of any given points are input, the coordinate of an asked for position relating to the given points is calculated and marking the asked for position. The measuring device for a coordinate of a figure comprises a body having rollers to trace a running line, a measuring lever pivoted on the body rotating right or left relative to the running line in a horizontal plane, characterized by a display, input device and a calculating device provided in the body, a tracing part, a reading/marking (writing) toggle switch, a reading switch and a marking needle provided in the measuring lever.

Disclosed is a method making use of a video camera, a programmed computer and a numerically-controlled machine-tool with three displacement axes. Particular transitions of the gray levels of the digitized output signal of the camera are sought. Two contiguous binary signals thus produced define a primitive segment of a line to be engraved. The directing parameters of the line segments, normalized in accordance with the displacement step of the machine, are produced and the successions of digital signals controlling the horizontal movement of the machine are deduced therefrom. The engraving depth control signals are renewed with each new engraving pass. Application to the customized production of jewelry and object-words.
