John R Zeno, Deceased

Title: John R. Zeno: Innovator in Ultrasonic Detection Technologies

Introduction

John R. Zeno was a notable inventor known for his contributions to ultrasonic detection technologies. He was based in New York, NY, and held a total of 2 patents during his career. His innovative work has had a lasting impact on the field of mechanical maintenance and lubrication.

Latest Patents

Zeno's latest patents include the "Ultrasonic Leak Detecting Lubrication Apparatus and Method of Use" and the "Ultrasonic Leak Detecting Apparatus." The first patent presents an apparatus designed to detect ultrasonic energy generated by mechanical devices while simultaneously applying lubricant. This apparatus features a lubrication tool, such as a grease gun, equipped with a lubrication delivery element. An ultrasonic transducer is attached to the lubrication tool, allowing for acoustical contact. The electrical circuit connected to the lubrication device produces an output signal indicating the magnitude of detected ultrasonic energy. This method aids in determining the condition of sealed mechanical rotating devices and the sufficiency of applied lubricant.

The second patent describes an ultrasonic leak detector characterized by a wide dynamic bandwidth and repeatable fixed attenuation reference points. It includes a transducer that converts received ultrasonic energy into an electrical output signal. A high gain charge preamplifier amplifies this signal, which is then processed through a multi-level logarithmic attenuator. The output is connected to a frequency shift circuit that converts the ultrasonic frequency signal into an audio frequency signal. This audio signal is amplified and used to drive a signal level indicator, providing insights into the magnitude of the output signal. This detector can also assess lubrication levels in sealed mechanical devices and detect potential mechanical failures.
