Title: Innovations of Louis E. Franceschina
Introduction
Louis E. Franceschina is a notable inventor based in Sault Ste. Marie, Canada. He has made significant contributions to the field of steel pipe hardening and quenching technologies. With a total of 3 patents to his name, Franceschina's work has had a lasting impact on industrial processes.
Latest Patents
Franceschina's latest patents include an "Apparatus for Inside-Outside Tube Quenching" and a "Steel Hardening Method." The apparatus for inside-outside tube quenching features a unique design that utilizes a tangential quench arrangement to cool the outside surface of long steel pipes while employing an axial flow nozzle to cool the inside surface. This innovative design ensures that both surfaces are cooled at approximately the same rate. The system includes a manifold with jet nozzles that can pivot apart, allowing for efficient transfer of the pipe into and out of the quenching arrangement. Additionally, a roller drive arrangement rotates the pipe in a stationary position, minimizing bow and enhancing cooling efficiency.
The steel hardening method involves an apparatus designed to harden elongated steel pipes by quenching them with a cooling medium, particularly water. This apparatus includes an elongated container to receive the hot pipe, a cooling medium nozzle for introducing the cooling medium into the pipe, and a mechanism to control the relative rates of cooling for both the inside and outside surfaces of the pipe. This method provides a comprehensive approach to steel pipe hardening.
