Abstract: A bicycle frame suspension comprises a single main tube having fore and aft ends and left and right sides with a head tube for rotatably mounting the front steering forks and front wheel secured to said fore end and a seat retention tube for mounting the seat secured to the aft end and bearings attached to either side of the main tube. A rigid rear triangle assembly has a bottom bracket for rotatably mounting the pedal and crank assembly. Left and right chain stay tubes have forward and trailing ends. A wheel fixing dropout is secured to each trailing end, respectively. The forward ends are secured to the bottom bracket. Left and right seat stay tubes have trailing ends secured in the proximity of the trailing ends of the chain stay tube and the dropouts, respectively. Pivot struts have upper and lower ends with the lower ends being secured to the bottom bracket, the upper ends being provided with bearing fittings and spaced apart a distance D and joined to forward ends of the seat stay tubes.

Abstract: In the case of a spindle for spinning or twisting machines, two housings, separated by an annular gap, are provided, namely an outer housing, secured to a spindle rail, and an inner housing which takes up the neck bearing and the step bearing for the shaft by means of supporting parts. The inner housing is connected to a supporting portion by a flexible joining piece, which supporting portion is adjustable and clampable onto the bottom surface of the outer housing. The bottom surface takes at least approximately the shape of a ball cup, whose center point is at most 30 mm away from the upper edge of the outer housing in vertical direction.

Abstract: A holding arrangement for a spindle of ring spinning or ring twisting machines. The holding arrangement includes a spindle housing which can be inserted in a receiving bore of a spindle rail and tightened by a ring flange and a nut screwed onto an external thread. The receiving bore includes a guide surface for guiding the spindle housing over only a portion of the length of the receiving bore while permitting tilting of the spindle housing in the receiving bore. Between the spindle rail and the ring flange and/or the nut, an adjusting ring is arranged which can be rotated when the nut is at least loosened. The adjusting ring is constructed as a non-uniform spacing element, by the rotating of which the relative position of the spindle housing and the spindle rail can be adjusted.

Abstract: In the case of a holding arrangement for a spinning or twisting spindle at a spindle rail, a holder is provided which has a fastening part that can be mounted at the spindle rail and a holding part receiving the spindle bearing housing. In addition, devices are provided for the adjusting of the relative position of the holding part with the spindle bearing housing with respect to the fastening part.

Abstract: A capstan or pressure roller shaft is journalled in a single one-piece elongated bearing member having a bearing surface sufficient to define radial position and inclination of the shaft. The bearing member is aligned with respect to a mounting support on the tape recorder, to adjust shaft alignment, by two axially spaced cylindrical positioning surfaces which are received in axially spaced cylindrical receiving surfaces in the support. At least one of the positioning surfaces is eccentric with respect to the bearing member, and is fixed to the bearing member so that rotation of the bearing member about an axis defined by the receiving surfaces adjusts the inclination of the shaft. The shaft inclination may be adjusted by inserting a tool into the tape recorder, engaging a journal formed in a mounting support adjacent the bearing member, the tool having a gear which engages a toothed portion on the bearing member for rotating the bearing member about the support axis defined by the support receiving surfaces.

Abstract: A thrust bearing assembly is provided which reduces initial axial loading on a shaft's thrust bearing in order to correspondingly reduce the required torque for rotational start-up. The shaft's bearing runner is forced in a direction away from its associated thrust bearing during initial start-up procedures by a suitable means for imparting a force on the bearing runner in a direction away from the thrust bearing. The force is provided by a piston and cylinder combination, in the preferred embodiment, which provides an axial force in a direction opposing the initial shaft loading force. An anti-friction guide bearing is used to transfer this force from the piston to the shaft and, in turn, to the bearing runner.
