Filed:

Jul 30, 2007

Appl. No.:

12/375710

International Classification:

A61B 17/00
A61F 5/00

US Classification:

606 80, 606 87

Abstract:

An instrument system, associated milling or drilling guide and method include use of a trial implant of a size corresponding to an actual implant for the intervertebral space, with a milling guide mounted on the trial implant. The milling guide includes a longitudinal guide chamber which is tapered from a forward end to a rearward end. The system also includes a cutting tool which is received in the guide chamber in order to form a cutout in an adjacent vertebra. This cutting tool includes a bearing member which pivotally engages the rearward end to form a pivot axis for the cutting tool in the tapered guide chamber. Either the milling guide can be inverted to form the cutout in the other vertebra; or the milling guide can be provided with two guide chambers, to be used with one cutting tool moved between them or two respective cutting tools.

Assignee:

The Babcock & Wilcox Company - New Orleans LA

International Classification:

F16L 1700

US Classification:

285 98

Abstract:

An improved spherical swivel joint assembly that substantially connectedly seals consecutively disposed conduit sections while allowing simultaneous angular and lateral joint displacement due to forces exerted at the joint during the transport of fluid therethrough.

Appl. No.:

6/859278

Inventors:

Assignee:

The Babcock & Wilcox Company - New Orleans LA

International Classification:

F28D 1704

US Classification:

165 4

Abstract:

A labyrinth articulation joint (38) for use in the seal frame (35) of a rotary regenerative air heater (20). An internal labyrinth arrangement of intercooperating tabs (54,55) and slots (44,45) in the two hinges (41,51) of the labyrinth articulation joint (38) present a series of successive right angle turns that increases the pressure drop through the labyrinth articulation joint (38) thus reducing the leakage of air through the labyrinth articulation joint (38), and thereby minimizing erosion of the labyrinth articulation joint (38) due to abrasive particles that would otherwise be carried through the joint by the leakage air.

US Classification:

110104B

Abstract:

Inventors:

David W. Gerber - Massillon OH

Assignee:

The Babcock & Wilcox Company - New Orleans LA

International Classification:

F16L 2700

US Classification:

285 11

Abstract:

A floating seal for a rotating pipe joint joins two generally parallel and axially aligned pipes and provides a substantially fluid tight seal between them, while permitting relative rotation of the two pipes as well as limited relative lateral movement of the two pipes. The joint also accommodates dimensional changes, particularly in length, such as those generated by temperature change. A preferred embodiment includes a floating seal assembly having a plurality of spaced parallel circumferential grooves about the inner wall of the aperture which retain mating compression rings which are inwardly biased against the inlet pipe.
