Patent number: 11517831Abstract: An abatement system for pyrophoric chemicals where the materials are captured or controlled by a hazard volume and fed to a vaporizer in an oxygen deprived environment. Materials are heated until vaporized while mixed with nitrogen. The mixture exits the system through a reaction column. The system is monitored by oxygen sensors, smoke detectors and temperature sensors.Type: GrantFiled: June 25, 2019Date of Patent: December 6, 2022Inventors: George Andrew Rabroker, Michael Carleton Murphey

Patent number: 8905735Abstract: According to one embodiment of the invention, an engine system comprises a housing, an outer gerotor, an inner gerotor, a tip inlet port, a face inlet port, and a tip outlet port. The housing has a first sidewall, a second sidewall, a first endwall, and a second endwall. The outer gerotor is at least partially disposed in the housing and at least partially defines an outer gerotor chamber. The inner gerotor is at least partially disposed within the outer gerotor chamber. The tip inlet port is formed in the first sidewall and allows fluid to enter the outer gerotor chamber. The face inlet port is formed in the first endwall and allows fluid to enter the outer gerotor chamber. The tip outlet port is formed in the second sidewall and allows fluid to exit the outer gerotor chamber.Type: GrantFiled: March 29, 2010Date of Patent: December 9, 2014Assignees: The Texas A&M University System, StarRotor CorportionInventors: Mark T. Holtzapple, Andrew Rabroker, Michael Kyle Ross, Steven D. Atmur, Gary P. Noyes

Patent number: 6886326Abstract: An engine includes a compressor, and combustor, and an expander. The compressor compresses ambient air. The combustor burns the compressed air, and produces exhaust gasses. The expander receives the exhaust gases from the combustor, and expands the exhaust gasses. The compressor may be a gerotor compressor or a piston compressor having variable-dead-volume control. The expander may be a gerotor expander or a piston expander having variable-dead-volume control. Moreover, the engine may include a regenerative brake. The regenerative brake may include one or more valves coupled to the compressor, an expander clutch, and a compressor clutch. Specifically, during braking, the expander clutch is disengaged and the compressor clutch is engaged.Type: GrantFiled: January 17, 2003Date of Patent: May 3, 2005Assignee: The Texas A & M University SystemInventors: Mark T.

The compressor may be a gerotor compressor or a piston compressor having variable-dead-volume control. The expander may be a gerotor expander or a piston expander having variable-dead-volume control. In another embodiment, an engine comprises a piston compressor, a combustor, a piston expander, and a pressure tank. The piston compressor compresses ambient air. The combustor bums the compressed air, and produces exhaust gasses. The piston expander receives the exhaust gasses from the combustor, and expands the exhaust gasses. The pressure tank receives and stores the compressed air from the compressor.Type: GrantFiled: August 16, 2001Date of Patent: March 11, 2003Inventors: Mark T. Holtzapple, G. Andrew Rabroker
