Abstract: Superseding a prior version of a document, to which prior version a retention policy or other requirement has been applied, is disclosed. In some embodiments, an attribute of a retention policy indicates whether a document to which the retention policy has been applied is to be superseded by a subsequently created and/or saved version of the document. In some embodiments, the attribute is set by a logic or process configured to apply the retention policy to the document. If the retention policy indicates that supersede is enabled, in various embodiments when a subsequent version is created and/or saved, the prior version is promoted to the final phase of the retention policy that has been applied to it and automatically “qualified” for disposition as indicated in the final phase of the retention policy, without regard to intervening requirements, processes, phases, approvals, retention, waiting, or other periods, etc.

Abstract: A vane for a variable diffuser includes a body with an inlet end and an outlet end, a leading surface extending from the inlet end to the outlet end, a trailing surface opposite the leading surface and extending from the inlet end to the outlet end, a first surface extending from the inlet end to the outlet end, and a second surface opposite the first surface and extending from the inlet end to the outlet end. The vane further includes a first cavity on the first surface of the vane adjacent the inlet end, a second cavity on the first surface of the vane adjacent the outlet end, a third cavity on the second surface of the vane adjacent the inlet end, and a fourth cavity on the second surface of the vane adjacent the outlet end.

Abstract: An annular backing plate for a diffuser in a centrifugal compressor comprises an inner diameter and an outer diameter disposed radially opposite the inner diameter. The backing plate also includes a first surface extending between the inner diameter and the outer diameter of the backing plate. A step is formed on the first surface proximate the inner diameter, wherein the step shifts a portion of the first surface encompassed by the step axially aft relative a portion of the first surface not encompassed by the step.

Abstract: 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.

Abstract: Polymorphic application of a policy is disclosed. An indication is received that a retention policy is to be applied with respect to an object. A rule is evaluated associated with the retention policy, in light of a circumstance of the object, to determine a manner in which the retention policy is to be configured to behave with respect to the object.

Abstract: A cover plate for use in a cabin air compressor is a generally cylindrical body with 19 holes extending through the body and an inner bore defining an inner diameter centered on a center axis. The body has a thickness in a dimension measured perpendicular to the central axis. The inner diameter is 14.840 inches (37.693 centimeters) plus/minus .005 inch (0.013 centimeter). A diffusor housing, a cabin air compressor and a method of replacing a cover plate are also disclosed.

Abstract: An air bearing shaft for a cabin air compressor includes a first edge and a second edge, a surface extending between the first edge and the second edge, and chrome plating on the surface between the first edge and the second edge. L1 is a first distance from the first edge of the air bearing shaft to a first end of the chrome plating. L2 is a second distance from the first edge of the air bearing shaft to a second end of the chrome plating.

Abstract: 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.
