  • Patent number: 8235176
    Abstract: A lubrication and scavenge system for a gas turbine, capable continued operation in nose-down or nose-up orientations, has a number of oil drainage passages to return oil to one or more collection chambers adjacent a rolling element bearing. A rotary impellor in the chamber forces the oil into a scavenge off-take passageway in the chamber wall leading to a scavenge pump. However, in some orientations windage effects in the chamber can return the oil to the drainage passage rather than permitting the impellor to centrifuge it into the off-take passageway. As a result oil starvation may occur. To avoid this and improve scavenging a shield is located between the drainage path and the off-take passageway adjacent to a face of the impellor. The shield may comprise an additional member, but preferably is formed integrally with a bearing race so as to ease assembly.

  • Publication number: 20030213806
    Abstract: A cradle or holder device is adapted, in use, to engage a liquid-filled carton or like container so as to enhance pouring of the contents from the carton. The device includes a body member including a backing portion and a carton gripping portion for gripping and holding a carton. The backing portion and gripping portion define a space having a cross section corresponding to that of the carton so that the carton, when received in the space, engages the inner surface of the backing portion and the inner surface of the gripping portion. A handle is affixed to the outer surface of the backing portion so as to enable gripping thereof by a user to thereby enable pouring from a carton received in the space.
