Abstract: METHOD FOR IMPROVING PRINT QUALITY OF          COARSE-SCAN/FINE-PRINT CHARACTER REPRODUCTION          ABSTRACT OF THE DISCLOSURE      A directional biasing method enhances the print quality of coarsely scanned characters.  A coarse scanning device produces analog signals that are compressed by encoding common information in a run length coding and encoding at least an edge of the character information according to a grey level indication.  The data information is reproduced wherein the grey scale information is decoded to represent a finer print than the picture element scanned.  The biasing and placement of the dots is set according to the grey scale, of the surrounding picture elements.  Eight sums are obtained of various groups of three peripheral picture elements corresponding to eight patterns located symmetrically on both sides of 4 bisecting lines, vertical, horizontal and two 45° lines.  A particular matrix of print dot placement is selected according to the largest pattern sum among the eight possible cases.  The dots in each matrix are designed to being strongly biased toward the direction of the associated pattern.

Abstract: FAIL-SAFE MONITOR OF A D.C. VOLTAGE            ABSTRACT OF THE DISCLOSURE         In some circumstances it is important to maintain a d.c. potential within a specific range of a critical value.          The circuit shown will provide a fail-safe signal if the po-tential deviates from the allowed range.  Two zener diodes and two optically coupled isolators are used.  If the d.c. potential remains within the critical range, an a.c. test signal back biases one optically coupled isolator and forward biases the other on the positive half cycle; and on the nega-tive half cycle back biases the other and forward biases the one.  Thus the two optically coupled isolators conduct on alternate half cycles of the a.c. test signal.  If the d.c. potential strays from the required range, the optically coupled isolators stop alternate conduction and a fail signal is given.          If either zener diode should fail in a mode which alters its characteristics so that the circuit would fail to detect a voltage excursion outside the allowed range, a fail signal is given.

The measurements are made 90° apart with respect to the gob and are utilized to determine the volume of each section of the gob. The volumes of the individual sections of the gob are then summed to determine the total volume of the gob.  An image of the gob is generated on a television screen to aid in the determination of the shape of the gob.
