Title: The Innovations of William A. Hanger
Introduction
William A. Hanger is a notable inventor based in Churchville, VA (US). He has made significant contributions to the field of printing technology, holding a total of 4 patents. His work has been instrumental in advancing the functionality and efficiency of impact printers.
Latest Patents
One of Hanger's latest patents is a "Bounce control system for moving coil printing element." This invention involves a drive circuit for an electromagnetic printing element of an impact printer. The drive pulse propels the printing element from a backstop toward a record medium to print indicia. A voltage comparator detects the change in the induced voltage in the printing element upon impact with the backstop. This triggers a single shot circuit that applies a damping pulse to counteract the rebound from the backstop. Additionally, a latch circuit responds to the damping pulse, disabling the single shot circuit until the next drive pulse concludes. The drive and damping pulses are delivered to the printing element through a bidirectional current source.
Another significant patent is the "Printhead compensation arrangement for printer." This invention describes an impact printer equipped with a control circuit that adjusts the actuation location of the printing elements in the printhead. This adjustment compensates for the flight time of the elements and other mechanical characteristics of the printer, enhancing overall printing accuracy.
