Abstract: A spindle assembly for a lawnmower comprising a housing having an opening and a spindle at least partially disposed within the housing. The spindle includes a flange extending radially outwardly from the spindle within the opening and being spaced from the housing. A bearing is disposed within the housing and connects the spindle to the housing for rotational movement with respect to the housing. A seal is positioned within the housing between the flange and the bearing. The seal is a generally ring shaped member extending around the spindle and comprises a body made from a rigid material and and a lip made from a flexible material. The body is connected to the housing and is fixed with respect to the housing. The lip is connected to the body and contacts the spindle, the spindle being rotatable with respect to the seal.

Abstract: A solar energy collection apparatus comprising a hollow generally spherical means having an energy receiving means located substantially at the center of the spherical means. Circulation means connected to the energy receiving means circulates a heat absorbing fluid through the energy receiving means. A lense means forming a portion of the spherical means is located in the upper portion of the spherical means. The lense means is positioned so as to direct and concentrate solar energy onto the energy receiving means and onto the inner surface of the spherical means. The inner surface of the spherical means upon which the solar energy is directed by the lense means includes a reflective material to thereby reflect the solar energy impinging upon said inner surface back to the energy receiving means.
