Abstract: A method for temporarily sealing a turbocharger compressor outlet and the seal for doing same are disclosed. The seal may include a layer of lubricant, a cover, and a layer of heat-shrink material. The seal creates a temporary water-tight seal around a turbocharger compressor outlet preventing damage to the inside of the turbocharger while the turbocharger is not in use.

Abstract: A first stage rotor disk (50a) and a connecting member (30) on the compressor side are fixed by a spindle bolt (20). The spindle bolt (20) is covered with a tubular member (100), between the first stage rotor disk (50a) and the connecting member (30) on the compressor side.

Abstract: Metal wire bundles are combined into brushes as a run-in coating for the axial-flow compressor stage of a gas turbine engine. The metal wire bundles are inserted into the basic material or are combined into brush segments that are inserted into corresponding recesses of the rotor housing.

Abstract: An apparatus (10) includes a bearing (24) linking first and second vehicle parts (12, 14) for movement relative to each other, and a boot seal (30) protecting the bearing (24). The boot seal (30) is a tube of heat shrinkable thermoplastic material. The tube (30) has a first end portion (34) shrunken against the first vehicle part (12), a second end portion (42) shrunken against the second vehicle part (14), and a flexible intermediate portion (44) which is deflectable between the opposite end portions (34, 40) upon movement of the vehicle parts (12, 14) relative to each other.
