Abstract: A system, apparatus (60) and method (20) of determining an average axis of rotation (Wf) and defined center of rotation (Cr) of a rotatable device (10) having a rotation axis which is nominally fixed in global coordinates (X,Y,Z) and having a plurality of target points (P1-PN) affixed thereon. It comprise a data collector (62) for obtaining target point location data from the device target points (P1-PN) for a plurality of rotated positions, a transformer (64) for translating and rotating the target point data in global coordinates, and an iterative algorithm (66) for positioning a secondary coordinate system (U,V,W) to be coincident with the axis of rotation (Wf), and defined center of rotation (Cr) of the rotatable device (10).

Abstract: A mechanical strain isolator mount 10 is provided to preserve the alignmental integrity of alignment sensitive instrument 25. Alignment sensitive instrument 25 is mounted on rectangular base 11. Flexural legs 15, 16, and 17 are connected at their proximal ends to rectangular base 11 at points, A, B, C, respectively. Flexural legs 15, 16, and 17 are also spaced parallel to sides AB, BC, and CD respectively. Mounting pads 20, 21, and 22 are respectively connected to legs 15, 16, and 17 at the distal ends thereof and attach mechanical strain isolator mount 10 to substrate 30 by means of threaded bolts 23. When a mounting pad and its respective leg is subjected to lateral strains in either the X or Y directon via substrate 30, the respective leg relieves the strain by bending in the direction of the strain. An axial strain on a mounting pad in the Z direction is relieved by a rotational motion of legs 15, 16, and 17 in the direction of the strain.

Abstract: A liquid is dispensed to a receiving surface by feeding the liquid under pressure to a dispensing orifice surrounded circumferentially by a convex toroidal boundary surface which is non-wettable by the liquid to form a liquid droplet perimetrically contacting the toroidal boundary surface in a manner which resists lateral displacement of the droplet relative to the orifice, and effecting relative movement of the receiving surface past and in wiping contact with the droplet to transfer liquid from the droplet to the receiving surface while regulating the delivery rate of liquid to the orifice to maintain the droplet. The invention is described in the context of roller bearing lubrication.
