Title: **Daniel J. Moynihan: Innovator in Dust Control and Mining Technology**

Introduction

Daniel J. Moynihan, a notable inventor based in Chelmsford, MA, has made significant contributions to the fields of mining technology and dust control. With a total of six patents to his name, Moynihan's innovations are particularly impactful in improving safety and efficiency in coal mining operations.

Latest Patents

Among his latest patents is a **Dust Control System and Method of Operation**, which is designed to effectively manage respirable dust in coal mining environments. This system involves a comprehensive ductwork assembly that includes intakes near the mining machine's cutter head, a fan to draw air through the system, and a flooded bed scrubber that captures dust particles by entraining them in water droplets. The air stream then carries these droplets downstream, where a sump and demister work together to separate the dust-laden water, ultimately allowing it to be recycled. This invention represents a significant step forward in mitigating the health risks associated with coal mining.

Another innovative patent is the **Gauging Apparatus and Method**, which enhances the mining process by controlling the extraction of material. Moynihan's apparatus employs electrical signals to manage the cutter's movement, ensuring that miners avoid unwanted materials, such as clay, by automatically adjusting the cutting rate as it approaches critical interfaces. This not only maximizes the recovery of desired resources but also minimizes operational disruptions.
