Patent number: 10850855Abstract: A method is disclosed for removing ozone from a gas. According to this method, the gas is contacted with an adsorbent that includes a transition metal oxide or metal organic framework to form a treated gas. The treated gas is contacted with a noble metal catalyst to catalytically decompose ozone in the treated gas, thereby forming an ozone-depleted treated gas.Type: GrantFiled: April 22, 2019Date of Patent: December 1, 2020Assignee: HAMILTON SUNDSTRAND CORPORATIONInventors: Tianli Zhu, Catherine Thibaud, Zissis A. Dardas, Daniel G. Goberman, Paul E. Hamel, John G. Sarlo

Patent number: 10443619Abstract: A motor housing assembly for a cabin air compressor assembly is provided that includes a central body portion, a first end portion, and a second end portion. The central body portion has an internal cavity configured to receive an electric motor. The first end portion includes a first and second motor cooling inlet duct. The second end portion includes a flange configured to couple with an outlet housing of the cabin air compressor assembly. A motor cooling duct centerline is defined between the first and second motor cooling inlet duct and is perpendicular to a central body portion centerline. A first distance is defined between an outer edge of the first and second motor cooling inlet duct. A second distance is defined between an outer face of the flange and an intersection of the centerlines. A ratio of the first distance to the second distance is between 1.29 and 1.3.Type: GrantFiled: December 31, 2014Date of Patent: October 15, 2019Assignee: HAMILTON SUNDSTRAND CORPORATIONInventors: Darryl A. Colson, Brent J. Merritt, Paul E. Hamel, David Anderson, Jr.

Publication number: 20110023513Abstract: A refrigerant expansion valve for a refrigerant system includes a main body, a motor and first and second members. The main body has a refrigerant flow passage that extends therethrough. The first and second members are connected together and are configured with threads that have a different pitch to allow for relative movement between both members and the main body. The motor is positioned adjacent the main body and is coupled to the first member. The motor actuates the first member in response to control signals to move the second member within the main body to modulate the flow of refrigerant through the refrigerant flow passage.Type: ApplicationFiled: July 28, 2009Publication date: February 3, 2011Applicant: HAMILTON SUNDSTRAND CORPORATIONInventors: Paul E.
