Title: The Innovative Contributions of David R Deetz

Introduction

David R Deetz is a notable inventor based in Dallas, TX, who has made significant contributions to the field of printing technology. With a total of 6 patents to his name, Deetz has focused on enhancing the performance and efficiency of impact printers. His work has been instrumental in advancing the capabilities of automatic typewriters and similar devices.

Latest Patents

One of Deetz's latest patents is the "Hammer driver controller for impact printers." This invention aims to achieve a substantially uniform print density while printing at high speeds. The hammer in the printer is electromagnetically driven in response to an energizing current that decays with a predetermined time constant. This allows for the impact energy imparted to the hammer to be regulated based on the character being printed. Additionally, to absorb the shock forces generated by the rebounding hammer, the energizing current is reduced to a predetermined fraction of the set point level.

Another significant patent is the "Enhanced underscoring methods and means for automatic typewriter." This invention enables automatic typewriters equipped with hammer-type impact printers to print straight and uniformly dense underscoring lines. It provides a method for automatically forming multiple character underscores from overlapping underscore characters. Furthermore, it optimizes the appearance of the underscoring by centering single or multiple character underscores relative to the characters being underscored.
