Title: The Innovations of Cornelius J Kelly
Introduction
Cornelius J Kelly is a notable inventor based in Simsbury, CT (US), recognized for his contributions to the field of electrical engineering. He holds a total of four patents, showcasing his innovative spirit and technical expertise. His work primarily focuses on positive temperature coefficient (PTC) devices and their compositions.
Latest Patents
One of Kelly's latest patents involves PTC devices and their composition. These PTC devices comprise a blend of at least three carbon blacks as a particulate filler in a fluorinated polymer. This unique combination achieves a substantial PTC effect and operability over a wide temperature range, including conditions prevalent in a steam environment. Two of the carbon blacks are specifically selected to impart the PTC effect to the composition, while the third carbon black is chosen to adjust the resistive properties of the composition. This adjustment ensures uniformity of the resistive properties within a given batch and across different batches. Another significant patent by Kelly details a method of manufacturing an electrically conductive composition. This process utilizes highly electrically resistive carbon black, either alone or in combination with low resistivity carbon black, to create a self-limiting electrically resistive semiconductor. This invention presents a positive temperature coefficient of resistance and offers significantly shortened anneal times, enhancing manufacturing ease and reliability.
