Abstract: A miniature kite includes a planar cover sheet, a frame, a control line and an elongate, flexible tail. The frame is formed of first and second diagonally overlapped, joined struts. A third strut overlaps and is joined to the intermediate overlap point of the first and second struts. The ends of the first, second and third struts are adhesively joined to one major surface of the sheet. The tail has an extremely long length relative to the length of the struts of the frame. Preferably, the first and second struts have a length of substantially 5.50 inches, the third or cross strut has a length of substantially 3.75 inches and the tail has a length of substantially 6 feet. The peripheral edges of the sheet have a shape substantially the same as the boundary between the ends of the first, and second and third struts.

Abstract: A bearing mounting device and bearing for economical replacement of worn and damaged bearings in a machine housing is disclosed. The bearing mounting device comprises a radially expandable sleeve having radially movable segments along the periphery thereof and a tapered, threaded bore. A bearing with a tapered, threaded outer diameter complementary to the threaded bore of the sleeve threadingly engages the bore of the sleeve, and tightening of the bearing into the bore expands the segments of the sleeve against the housing. With the tapered outer diameter of the bearing, when tightened securely in the bore the bearing and the sleeve are securely fixed in the housing. A spanner wrench is disclosed for rotating the outer race of the bearing into engagement with the sleeve, and a second spanner wrench is disclosed for preventing rotation of the sleeve during insertion of the bearing.
