Title: Innovations by James J Doyle

Introduction

James J Doyle is a notable inventor based in Cambridge, GB. He has made significant contributions to the field of printing technology, particularly in ink jet printing systems. With a total of 3 patents to his name, Doyle's work has advanced the efficiency and functionality of ink jet printing.

Latest Patents

Doyle's latest patents include a method for operating a continuous ink jet printing system. This innovative method involves a nozzle that is vibrated by a piezoelectric oscillator. The nozzle passes a stream of ink past a charging electrode, where the continuity of charge detection is sensed by a charge detector positioned downstream. The amplitude of the stimulation voltage applied to the piezoelectric oscillator is initially set low, allowing the charge detector to detect levels below a threshold value. The voltage is then increased in discrete steps until proper droplet charging is achieved.

Another significant patent is for an ink jet droplet generator with a quick-release nozzle cap. This design features a piezo-electric ink jet droplet generator with a body part that includes multiple ink supply passages. A piezo-electric crystal is strategically placed to enhance the functionality of the ink supply system. The nozzle is mounted in a cap that is secured to the body, allowing for efficient ink flow and quick release capabilities.
