Title: Innovations by Lawrence A. Gawne
Introduction
Lawrence A. Gawne is an accomplished inventor based in Wixom, MI (US). He has made significant contributions to the field of paint circulation systems, holding a total of 2 patents. His innovative approaches aim to enhance efficiency and reduce waste in painting processes.
Latest Patents
Gawne's latest patents include a method of flushing a circulation system using first and second rigs. This cleaning system is designed to automate and minimize or eliminate the excessive amount of manpower associated with other suction processes. It combines paint recovery and flushing methods in an automated manner. The system minimizes paint loss during color changes in circulation systems and reduces the time and solvents used in the cleaning process. This is achieved by inserting a first pig into the circulation system at the end of a desired painting cycle to push out the paint, propelling the first pig through the system using a solvent. The location of the first pig is then sensed, and it is collected from the system. A second pig is injected into the system to separate the solvent from a new cycle of paint.
Another notable patent is the paint circulating method with a viscosity indicator and paint agitating. This invention provides a paint circulation system for supplying paint to multiple distributors. It utilizes a circulating pump to circulate paint and an injection pump operated by a closely controlled electric motor for injecting paint into the circulation network. This maintains a predetermined pressure within the circulation network. A 'leakage' passage with a predetermined restriction allows paint to leave the circulation network when the valved paint distributors are closed. The use of an automatic timing valve within the leakage bypass permits flow rates within the circulation network to be varied. The components of this system help determine paint viscosity and volumes, minimize settling of paint particles, and reduce degradation of circulating paint.
