Abstract: METHOD AND APPARATUS FOR CONTROLLING A PRINTER                    ABSTRACT OF THE DISCLOSURE A method and apparatus for controlling a printer of the type having plural print heads, each being selec-tively energizable to print an indicium whose relative intensity is determined by the duration of energization of that printer.  Data representing the intensity of the indicia to be printed by each of the print heads is received and stored.  Respective ones of the print heads are selectively energized over time durations determined by the data.  The number of print heads which are energized is detected, and the duration that the respective print heads are energized is varied as a function of the number of print heads which are concur-rently energized.

Abstract: Abstract:    The present invention relates to a method and a device for use in measuring the gradient of density in a fluid.  The device is comprised of a laser for providing a columnar light beam and a photodetector axially aligned with the laser.  The photodetector detects the displacement of the light beam caused by the gradient of refraction of the fluid.  A unit is provided for converting the displacement into an indication of the gradient of refraction and thereby the gradient of the density of the fluid.  For density gradients caused by concentration gradients, an additional unit is provided for converting the displacement into a measure of the quantity of substances in the fluid.

Abstract: Abstract of the Disclosure A fully automatic penetration hardness tester which, includes a penetrator and clamp driven by respective serially-connected pneumatic cylinders for engaging test specimens.          Pressure regulators are coupled to the respective cylinders for first applying clamping pressure against the test specimen and then applying a plurality of loads in a predetermined sequence to the clamped specimen through the penetrator, with the total clamping and penetrator pressure against the test specimen remaining constant through the test cycle.  A control circuit monitors penetrator position and automatically initiates application of the next load in the test sequence when motion of the penetrator following application of the preceding load has settled such that a predetermined number of sequential position readings fall within a preselected position range.          Specimen hardness is determined as a linear function of penetration depth under the various loads.  An automatic calibration feature determines gain and offset of such linear function from actual and apparent hardnesses of two test specimens of known differing hardness.
