Abstract: A method for reducing stress concentration on a rotor sleeve during balance cutting comprising: providing an axial protrusion to an outer diameter of a first end cap and a second end cap of a rotor assembly; and radially cutting at least one of the sleeve or the axial protrusion to balance the rotor assembly.

Abstract: A turbocharger rotating assembly (125) includes a shaft (20) rotatably supported in a bearing housing (123) via bearings (26, 128), a compressor impeller (18) mounted on the shaft (20), and an oil flinger (122) disposed on the shaft (20) between the bearings (26, 128) and the compressor impeller (18). The turbocharger (100) further includes an insert (134) disposed in the shaft-receiving axial bore (120) so as to surround the oil flinger (122), and a purge seal (160) operatively positioned in an interface (131) between the insert (134) and the oil flinger (122), whereby the purge seal (160) is configured to minimize oil passage from the bearing housing (123) into the interface (131). An annular cavity (150) encircles the radially outward-facing surface (138) of the insert (134), the cavity (150) forming a portion of a fluid path configured to deliver pressurized fluid to the interface (131).

Abstract: A number of variations may include a product for use with a turbocharger system may include an electric motor with a rotor rotating about an axis. The rotor may operate through a bending critical mode. A magnet may be disposed in the rotor. The rotor may be provided with a selected amount of compliance to tune the bending critical mode to occur at a selected rotational speed.

Abstract: The present invention provides a latch device and method for securing a panel such as a door panel to a frame. The latch device has a housing mounted to the door panel with a catch having a contact portion pivotally mounted in the housing for rotation about a first axis while a handle assembly is mounted in the housing for rotation about a second axis. A strike is mounted on the frame such that the strike can receive the catch. The handle assembly is moveable between a first position where the contact portion of the catch is urged into contact against the strike and second position where the catch is retracted from the strike. A link is pivotally mounted to the catch at one point and to the handle assembly at a second point. An adjustment device is provided. The latch device also has a compliance element that absorbs forces resulting from the engagement of the latch assembly.

Abstract: An ultra-low temperature refrigeration system (10) comprising a housing (12) and a door (14) which together define an interior storage compartment (16). The system (10) uses multiple layers (20,22) of varying insulative materials to insulate the housing (12), including conventional foam (20) and vacuum insulation panels (22), to balance cost, size, and capacity considerations. The vacuum insulation panels (22) are provided with beveled edges (26) or otherwise positively interfacing edges so as to overlap adjacent panels and present a more reliably insulative seam. The system (10) further includes a self-defrosting pressure equalization port (30) for automatically equalizing interior and exterior pressures.

Abstract: A de-icing system operable to facilitate the removal of ice from the door (18) and closure surface (22) of a low temperature refrigeration or ultra-low freezer device (10) and to thereby ensure proper operation of the device (10) and protect its contents. The de-icing system employs manually activated heaters (32) and a timing circuit (38) to thaw the ice. Because the de-icing system focuses heat only on specific, ice-sensitive areas, the temperature of the freezer's interior compartment (14) remains constant so that the contents need not be removed during the de-icing process. In use, an operator activates the de-icing system a few minutes prior to opening the freezer door (18). When the door (18) is opened, the melted or loosened ice can be removed with a soft cloth. If the operator forgets that the heaters have been activated, the timing circuit (38) automatically terminates the de-icing process and stops the heaters (32) before the freezer's interior storage temperature has been affected.
