Vessel centering system and method
First Claim
1. A vessel adapted for improved centering with respect to a spindle or other instrument when installed in a vessel plate, the vessel comprising:
- (a) a vessel wall including an outer surface and a vessel groove formed on a circumference of the vessel outer surface;
(b) an annular spacer member fitted in the vessel groove and comprising a first lateral end surface and an opposing second lateral end surface, a radially outermost spacer member surface coaxial with the vessel outer surface, and a cross-section extending outwardly with respect to the vessel wall to the spacer member surface, the cross-section terminating at the first lateral end surface and the second lateral end surface, the first and second lateral end surfaces defining a gap therebetween; and
(c) a fastening element engaging the first and second lateral end surfaces, extending across the gap, and disposed within the cross-section.

Abstract
A vessel centering system comprises a vessel, an annular, spacer member, a fastening element, and an elastometric component. The vessel includes an outer surface and a vessel groove formed on a circumference of the vessel outer surface. The spacer member is fitted in the vessel groove and extends outwardly with respect to the vessel. The first and second lateral end surfaces define a spacing therebetween. The spacer member includes a tangential bore and an annular groove. The tangential bore extends along a line generally tangential to a curvature of the spacer member. The fastening element, which could be a screw, is disposed in the tangential bore in engagement with the ring member and extends across the ring spacing. The elastometric component, which could be a gasket or O-ring, is disposed in the annular groove. A plurality of biased bearings can be provided instead of the elastometric component. When the vessel is installed in the aperture of a vessel plate, concentricity between the inner surfaces of the vessel and a shaft extending into the vessel is easily obtained.

6. A vessel adapted to be centered with respect to a spindle or other instrument when installed in a vessel plate, the vessel comprising:
-
(a) a vessel wall including an outer surface and a vessel groove formed on a circumference of the vessel outer surface;
(b) an annular spacer member fitted in the vessel groove and extending outwardly with respect to the vessel wall, the spacer member including a spacer member outer surface coaxial with the vessel outer surface, a first lateral end surface, a second lateral end surface opposing the first lateral end surface, a first tangential bore extending from a first outer aperture of the spacer member outer surface to a first inner aperture of the first lateral end surface, and a second tangential bore extending from a second outer aperture of the spacer member outer surface to a second inner aperture of the second lateral end surface, wherein the first and second lateral end surfaces define a gap therebetween, and wherein the first and second tangential bores extend along a line generally tangential to a curvature of the spacer member; and
(c) a fastening element disposed in the first and second tangential bores, the fastening element extending through the first inner aperture, across the gap, and through the second inner aperture, wherein the fastening element is movable along the generally tangential line of the first and second tangential bores to engage the spacer member and tighten the spacer member in the vessel groove. - View Dependent Claims (7, 8, 9)
