Abstract: A scanner has a plurality of cameras positioned around an object to be scanned. The object is illuminated by unstructured light and the object is covered by a textured surface. The cameras can be arranged as pairs and each camera pair is supported on a single support. The scanned object can be a foot, among other things, and the scanner is positioned at a predetermined incline so that the foot is evenly supported. A positioning system, either visual or automatic, is included on the scanner platform. If automatic, a sensor array is affixed to the platform such that a scan will only initiate when certain sensors or combinations of sensors are ON. Method for attaching the camera pairs on the support, method for calibrating the camera pairs and method of scanning the foot to provide shoe sizes and shoe lasts are also disclosed.

Abstract: Wet rotor circulators are provided, in which a fixed volume of a control fluid is sealed within the rotor chamber, and the rotor chamber is sealed against entry of the circulating system fluid.

Abstract: The present invention is a spherical compliant load ring that serves as the interface between the bearing and the bearing housing of a self-aligning bearing assembly and allows the use of a standard cylindrical cartridge bearing. The spherical compliant load ring is an annular structure with a spherically convex surface that is used to mate with the spherically concave surface of the bearing housing.
