Patent number: 8979026Abstract: A compressor for pressurizing a flow of air within an aircraft including an inlet providing the flow of air to the compressor. An outlet provides the flow of air, after pressurization by the compressor, to a chamber of the aircraft. A diffuser assembly is disposed between the inlet and the outlet. The diffuser assembly includes one or more vanes at least partially impeding the flow of air through the diffuser assembly. A backing plate is included having a surface adjacent to the one or more vanes. The surface includes a relief feature that enables air to bypass the one or more vanes. The relief feature has an axial depth of about 0.5% to 2.5% of a width of a flow path through the diffuser assembly or of about 0.5% to 5% of a thickness of a flange of the backing plate. A method of operating a compressor is also included.Type: GrantFiled: June 4, 2013Date of Patent: March 17, 2015Assignee: Hamilton Sundstrandt CorporationInventors: David A. Dorman, Harold W. Hipsky, Peter A. Wierzbowski, Eric Chrabascz, Brian Cabello

Publication number: 20140283521Abstract: A ram air fan assembly includes a motor/bearing housing that extends along a horizontal length of the ram air fan assembly. An inner housing assembly is in fluid communication with the motor/bearing housing to define a joint. The inner housing assembly includes first and second ellipse-shaped slots. The first slot is positioned at a first angle with respect to a radial axis of the inner housing assembly that is perpendicular to the horizontal length, and the second slot is positioned at a second angle with respect to the radial axis, the second angle being different from the first angle, and each slot extending along a first direction parallel to the horizontal length to define an axial width and extending along a radial axis to define a radial width being greater than the axial width.Type: ApplicationFiled: March 19, 2013Publication date: September 25, 2014Applicant: Hamilton Sundstrand CorporationInventors: Eric Chrabascz, William R. Fiske, David A. Dorman

Patent number: 8712980Abstract: Consistent retention and disposition of managed content and associated metadata is disclosed. An indication that a retention policy is to be applied to a selected item of content comprising a body of managed content is received. The selected item of content and its associated metadata are retained automatically in parallel in accordance with the retention policy.Type: GrantFiled: August 31, 2010Date of Patent: April 29, 2014Assignee: EMC CorporationInventors: Roger W. Kilday, John-David Dorman, David Humby, Fiona Schrader, Dan Bailey

Publication number: 20140037441Abstract: A disclosed ram air assembly includes a housing that defines an inlet and an inner cavity. A fan disposed at the inlet generates air flow and is driven by an electric motor. Airflow through the ram air fan assembly is directed through a passageway defined by a diffuser. The diffuser includes a first diameter at a forward end, and a second diameter at an aft end with the second diameter being larger than the forward end to diffuse airflow and increase fan efficiency.Type: ApplicationFiled: August 6, 2012Publication date: February 6, 2014Inventors: Eric Chrabascz, Victoria S. Richardson, David A. Dorman

Publication number: 20130097997Abstract: A diffuser for a ram air fan assembly includes a perforated cone, an inlet ring seal, and an outlet ring seal. The perforated cone has a frustoconical shape symmetrical about an axis of the diffuser. The inlet ring seal is attached to, and axially disposed about, a first end of the perforated cone. The inlet ring seal includes a fan housing connection having a cylindrical shape. The outlet ring seal is attached to, and axially disposed about, a second end of the perforated cone. An average external diameter of the second end is greater than an average external diameter of the first end such that the perforated cone extends away from the inlet ring seal and radially outward from the axis of the diffuser.Type: ApplicationFiled: October 24, 2011Publication date: April 25, 2013Applicant: HAMILTON SUNDSTRAND CORPORATIONInventors: Eric Chrabascz, Victoria S. Richardson, David A. Dorman

Publication number: 20130101400Abstract: A ram air fan inner housing for a ram air fan assembly comprises a center body housing, an end cup attached to the center body housing, and a perforated cone. The perforated cone is attached to the center body housing and the end cup such that the perforated cone extends away from the center body housing and radially inward toward an axis of the inner housing.Type: ApplicationFiled: October 24, 2011Publication date: April 25, 2013Applicant: HAMILTON SUNDSTRAND CORPORATIONInventors: Lawrence Binek, Eric Chrabascz, David A. Dorman

Patent number: 7970743Abstract: Retention and disposition of stored content associated with multiple stored objects is disclosed. An indication is received that a first stored object associated with an item of content comprising a body of managed content is no longer subject to retention under a retention policy applicable to the first stored object. The item of content is deleted or otherwise disposed of only if the item of content is not associated with a second stored object that is still required or desired to be retained.Type: GrantFiled: March 7, 2006Date of Patent: June 28, 2011Assignee: EMC CorporationInventors: Roger W. Kilday, John David Dorman, David Humby, Fiona Schrader, Dan Bailey

Patent number: 7801862Abstract: Retention of complex objects is disclosed. An indication is received that retention applied to a root object of a complex object is to be extended to child objects, such as attachments or included files or other content. A snapshot of at least the child objects is stored and the retention that is applied to the root object is extended to the snapshot. Retention of the snapshot ensures that the child objects are retained, so long as and in the same manner as the root object, in the form (e.g., version) in which they are stored at the time retention is applied to the snapshot.Type: GrantFiled: September 29, 2006Date of Patent: September 21, 2010Assignee: EMC CorporationInventors: David Humby, David Mennie, Steve Sauder, John-David Dorman
