Title: The Innovations of Kenneth A. Fowler
Introduction
Kenneth A. Fowler is a notable inventor based in Medfield, MA (US), recognized for his contributions to ultrasonic transducer technology. With a total of three patents to his name, Fowler has made significant advancements in the field of quality monitoring for welding processes.
Latest Patents
Fowler's latest patents include an ultrasonic transducer assembly designed for monitoring the quality of spot welds. This innovative assembly employs a transducer element joined to a support element, which is fitted within a conventional welding electrode assembly. The transducer assembly is biased against the interior surface of the welding electrode tip by a biasing element, preferably a compression spring. Additionally, a sleeve, typically made of brass, surrounds the transducer element and is connected to the support element. A coaxial cable in communication with external instrumentation has a ground lead attached to the sleeve and a signal lead attached to the transducer element.
Another significant patent is the sealed, matched piezoelectric transducer. This assembly is intended for making measurements within a fluid and includes a transducer, a backing member, and a matching member, all supported within a cylindrical metal housing. The transmitting face of the housing is sealed with a thin sealing element made of a non-resilient, relatively high impedance material, encasing a matching layer that has an acoustic impedance intermediate between that of the transducer element and the fluid. The thickness of the sealing element is carefully designed to be between 1/10 and 1/1000th of a wavelength at the center frequency of the wave emitted by the transducer.
