20090131178 - Torsional vibration damper arrangement: A torsional vibration damper with a primary side and a secondary side, wherein rotation of the primary side relative to the secondary side causes displacement of hydraulic fluid from at least one displacement chamber and compression of pneumatic fluid in at least one compensating chamber. A first displacement chamber assembly... Agent: Cohen, Pontani, Lieberman & Pavane LLP

20090131179 - Torsionally rigid flexible coupling, in particular fully-steel coupling: The invention relates to a torsionally rigid, flexible shaft coupling, in particular fully-steel shaft coupling, for transmitting torques between shafts, in particular shafts with axes which are offset relative to one another, having one or two plate packs (5) which are placed on flange sleeves (6) and, on the latter,... Agent: W. Norman Roth

20090131180 - Boot for universal joint: To make a bellows section (1) of a boot to be flexibly and repeatedly deformable without deterioration in durability, to thereby reduce rotational resistance when a joint angle is large, the boot has the bellows portion (1) where three or more circumferentially extending crest portions (111-113) and root portions (121-122)... Agent: Jacobson Holman PLLC

20090131181 - Filament wound composite shaft: A shaft may include a first coupling member, a second coupling member, a filament wound shaft member, and a pilot shaft. The first coupling member may couple the shaft to one of a rotationally driving and a rotationally driven component. The second coupling member may be axially spaced from the... Agent: Harness, Dickey & Pierce, P.L.C

20090131182 - Arrangement for releasably holding a component in a fixed position on a shaft: The arrangement comprises parts coaxially mounted on the shaft, the parts including: a lockplate in rotational engagement with the shaft, the lockplate having a first side and a second side, the first side of the lockplate being in engagement with the component; a nut in threaded engagement with the shaft,... Agent: Ogilvy Renault LLP (pwc)

20090124397 - Grease reduction insert: An articulating joint apparatus includes a first rotational member having an axis, a second rotational member coupled with and positioned generally coaxial to the first rotational member, and a boot cover assembly for sealing at least part of the first rotational member to the second rotational member. The boot cover... Agent: Gkn Driveline North America, Inc

20090124398 - Handle suitable for transmitting a torque between a rotation knob and a respective out put shaft connectable to cables, tubes, or the like: A handle (10) is suitable for transmitting a torque between a rotation knob and a respective output shaft connectable to cables, tubes, or the like, wherein said handle comprises at least first and second transmission lines which operate between a first rotation knob (12) and a first output shaft (22)... Agent: Philip S. Johnson Johnson & Johnson

20090124399 - Universal joint: A universal joint includes a tube having a hollow shape; a slip bush inserted into the tube; and a shaft assembled with the tube through the slip bush, wherein the slip bush includes power transmission parts, which are arranged along an circumferential surface of the slip bush in an axial... Agent: Harness, Dickey & Pierce, P.L.C

20090124400 - Rotation-transmitting apparatus with built-in one-way clutch: The present invention provides a rotation-transmitting apparatus with a built-in one-way clutch which is capable of preventing rolling contact surfaces and rolling surfaces of inner and outer rings of a rolling bearing from peeling and fretting wearing and is excellent in its resistance to heat and wear. The rotation-transmitting apparatus... Agent: Hedman & Costigan P.C.

20090118023 - Method of supporting an upper gearset of a marine stern drive: A support for the upper drive shaft of a marine stern drive unit. The support has an axial body installable in the axial bore of the upper case. Retainers on the body are engageable with the upper case to secure the support in place. One or both retainers are axially... Agent: Cr Miles, P.C. Craig R. Miles
