An apparatus wherein a spherical object is rotated on its equatorial axis (b-b) and its polar axis (a-a) adjacent a sensor (s) for detecting defects is described. The roller shaft (128) has spherical projections (129 and 130) and spaced apart parallel spindles or shafts (127) with a ball support (131) which provides centering of the spherical object or ball (B) regardless of the diameter. Preferably multiple test cage assemblies (12) are used for balls of various sizes to insure stability of the ball during testing. The apparatus is particularly used for testing of ballbearings for defects.

Apparatus and method for detecting defects in a spherical object

Detector apparatus (10, 50, 90) for measuring wind velocity and direction and/or ice accumulation. The apparatus preferably includes boots (14, 23, 24 and 70) for removing accumulated ice prior to measuring wind velocity and direction without the ice. A computerized system and program for determining the measurements in the detector apparatus.
