Title: John L Allen, Jr: Innovator in Diagnostic and Control Systems

Introduction

John L Allen, Jr. is a notable inventor based in Charlotte, NC (US), recognized for his contributions to the field of diagnostic and control systems. He holds 2 patents that showcase his innovative approach to improving manufacturing processes, particularly in the production of synthetic materials.

Latest Patents

One of his latest patents is a "Diagnostic and control system for cigarette filter rod making machine." This system is designed to monitor various operational variables of a filter rod making machine through strategically placed sensors. These sensors measure parameters such as the width of the tow, alignment of the wrapping paper, speed of the rollers, and level of plasticizer. The microprocessor compares these measurements against preset limits, providing operators with real-time feedback. If any variable falls outside acceptable ranges, the system alerts the operator, who can then choose to override the limits or take corrective action. The microprocessor also displays a diagnostic chart to guide the operator through troubleshooting steps, potentially preventing machine downtime.

Another significant patent is the "Method for determining level of finish and control thereof." This method involves continuous non-contact monitoring of electrostatic voltage (ESV), tow speed, and temperature using appropriate sensors. These sensors are interfaced with a computer that calculates the percentage of finish on the tow in real-time. If the finish application deviates from the desired levels, signals are relayed to adjust the amount of finish being applied, ensuring optimal quality control.
