Title: Innovations by John J Brull
Introduction
John J Brull is an accomplished inventor based in Chagrin Falls, Ohio. He has made significant contributions to the field of cryogenics, particularly in the development of advanced deflashing systems. With a total of three patents to his name, Brull's work showcases his innovative approach to solving complex engineering challenges.
Latest Patents
Brull's latest patents include a Cryogen Shot Blast Deflashing System and a Cryogen Shot Blast Deflashing Apparatus with Inert Gas Purging System. The Cryogen Shot Blast Deflashing System features an upstanding frame that supports a receptacle assembly, which includes a housing that encloses a rotatable drum. This system utilizes a throwing wheel to discharge particulate media and cryogen gas into the drum, effectively impacting workpieces to embrittle workpiece flash. A recirculation system is integrated to withdraw cryogen gas and particulates from the drum, separate reusable media from waste material, and return a controlled flow of pressurized cryogen gas and media to the throwing wheel. The versatility of this system is enhanced by adjustable parameters such as discharge patterns, drum rotation speeds, and treatment chamber orientation.
The Cryogen Shot Blast Deflashing Apparatus with Inert Gas Purging System also features a closed recirculation design. It includes a similar frame and receptacle assembly, with a throwing wheel for discharging media and cryogen gas. This apparatus incorporates a purging system that introduces inert gas, such as nitrogen, to maintain a positive pressure inert atmosphere, thereby inhibiting the entry of moisture-laden ambient air.
