Abstract: A tripod suitable for travel.

Abstract: An adjustable bearing assembly includes a bearing housing and a bearing body fixed to a carrier and disposed within the housing. Set screws are provided to adjustably position the carrier, hence the bearing body relative to the housing without disassembling the bearing. After the bearing body position has been adjusted, cap screws are employed to fix the carrier against movement relative to the housing and relative to a support surface. In an alternate embodiment, the carrier is in engagement with an inner eccentric ring which, in turn, is engaged by an outer eccentric ring, both rotatably mounted within the housing. The axes of the eccentric rings are spaced from one another and are parallel to the axis of the rotating shaft. Rotation of the eccentric rings relative to one another and to the housing adjusts the position of the bearing body.

Abstract: An adjustable tension foil bearing for a rotatable shaft comprises a bearing housing for the support of a plurality of foil carriers which carry a like plurality of foil elements. The foil carriers are rotatable to effect tensioning of the foil elements.

Abstract: An axial shaft is supported within a housing by a plurality of bearing foils which are cantilevered from the housing by a series of rotatably mounted supports. The supports are provided with gear teeth and a ring gear which surrounds the housing is engageable with the gear teeth of the supports to simultaneously rotate these supports relative to the housing and adjust the preload of the bearing foils against the shaft.
