Patent number: 11904283Abstract: A volatiles consuming eductor system for coated scrap metal furnaces with separate delacquering and melt chambers. Motive gas is forced through an inlet into a mixing chamber in a direction opposite a suction port, creating a Venturi that draws gases from the delaquering chamber through the mixing chamber. The motive gas and the drawn gases mix and are forced through a discharge port, ignited, and injected into the melt chamber to help heat the melt chamber. A computer monitors process conditions and controls a regulator that adjusts the motive gas flow in response to those conditions.Type: GrantFiled: June 25, 2021Date of Patent: February 20, 2024Assignee: GPRE IP LLCInventors: John M. Peterman, Mark A. Roberts, Mark J. Burke

Publication number: 20240011710Abstract: A vortex metal insertion system for a metal recycling furnace, the system having a molten metal flow cycling through the furnace and through a vortex bowl in the system. The system includes one or more process sensors in the furnace, an automated molten metal flow adjustment device, and a computer controller. The computer controller reads the sensor(s) and adjusts the adjustment device to control the flow of molten metal through the vortex bowl based on the reading(s). The system has an insertion port through which scrap metal and other materials may be controllably inserted into the molten metal flow.Type: ApplicationFiled: September 21, 2023Publication date: January 11, 2024Applicant: GPRE IP, LLCInventors: John M.

Patent number: 11835295Abstract: A metal furnace header gate system haying a recirculation port in the furnace, a hot gas generator, a gas blower, and a furnace door. The door has an embedded gas manifold and outlet ports that each connect the manifold to a directional nozzle. The blower draws exhaust from the recirculation port into the hot gas generator, which generates additional exhaust and mixes the exhaust gases together. The blower forces this exhaust mixture into the manifold, through the nozzles, and into the furnace. A computer controls the blower and the hot gas generator to regulate the system.Type: GrantFiled: July 9, 2021Date of Patent: December 5, 2023Assignee: GPRE IP, LLCInventors: John M. Peterman, Mark A. Roberts

Patent number: 11767575Abstract: A vortex injection system for a metal recycling furnace a delacquering chamber and a melt chamber, and a molten metal flow channel running through each chamber. The system diverts a portion of the molten metal flow through a vortex bowl, after which that portion of the molten metal flow is then returned to the main molten metal flow. The vortex bowl has an insertion port through which scrap metal and other materials may be controllably injected into the molten metal flow.Type: GrantFiled: July 9, 2021Date of Patent: September 26, 2023Assignee: GPRE IP, LLCInventors: John M.

Patent number: 11635258Abstract: An overflow system for a doorway exhaust hood on a metal melt furnace having an eductor gas circulator. The system includes a manifold with an inlet near the hood's lower lip, and a conduit between the manifold and eductor. A blower draws gas into the manifold and urges that gas through the conduit, into the eductor, and into the furnace. Sensors detect when the door is open and the volatiles level under the hood. An electronic controller instructs the blower to draw exhaust gases through the manifold when the door is open and the volatiles level exceeds a predetermined level.Type: GrantFiled: July 21, 2021Date of Patent: April 25, 2023Assignee: GPRE IP, LLCInventors: John M.

Publication number: 20230012244Abstract: An automatic variable speed eductor recirculation system for metal recycling furnaces having a delacquering chamber and a separate heating chamber. The system includes a recirculation duct between the two chambers, an eductor in the duct, a variable speed blower forcing motive gases into the eductor creating a Venturi that draws VOC's from the delacquering chamber through the eductor, and an infrared opacity sensor proximate the eductor that measures the transparency level of the gases in the eductor. An electronic controller automatically adjusts the blower speed to control the eductor Venturi based upon the transparency level measurements of the opacity sensor.Type: ApplicationFiled: June 9, 2021Publication date: January 12, 2023Applicant: GPRE IP, LLCInventors: JOHN M.

Publication number: 20220178660Abstract: An audible response self-healing target having a generally flat shell mated with a generally flat metal strike plate. The shell has a “self-healing” polymer “target zone”, and tabs that hold the metal plate parallel to the target zone with a small gap of approximately one-half inch. The shell rotatably mounts onto a pole, such that when a projectile, such as a bullet slug, impacts the target's strike zone, the slug penetrates the polymer and strikes the metal plate, kinetically causing the target to rotate about the pole and also causing the metal plate to generate an audible response.Type: ApplicationFiled: December 6, 2021Publication date: June 9, 2022Applicant: Saros Industries, LLCInventor: John M.
