摘要： A puck for playing hockey and hockey-like games on a variety of surfaces. The puck has a body of generally cylindrical shape with opposed major faces and an internal chamber therein containing a mass which is movable within the chamber whereby the center of gravity of the puck can be altered, as by application of a force to the puck in a direction generally parallel to the major faces. The puck body includes mating halves held together by a resilient band extending around the cylindrical sidewall of the body, the band having spaced ribs thereon mating with associated grooves in the sidewalls of the mating halves.

摘要： The invention relates to a mobile universal shop light particularly suited for use in illuminating various aspects of motor vehicles and related machinery during maintenance and repair. The mobile shop light of this invention is comprised of a lower stand mounted on means to provide mobility, a lower stand bar rigidly attached to the lower stand and which extends upward from the lower stand in a direction perpendicular to the plane of the lower stand, an upper stand bar which telescopes into the lower stand bar so as to allow the upper end of the upper stand bar to be positioned at different heights, means to secure the upper stand bar in position relative to the lower stand bar, attaching means connected to the upper end of the upper stand bar which adjustably attaches to the upper stand bar an elongated light fixture containing illuminating means and power supply means. The attaching means allows the fixture to rotate about its longitudinal axis and to be positioned with its longitudinal axis perpendicular to the upper stand bar and at intermediate angles to the perpendicular.

摘要： A plunger is described which utilizes the suction cup principle to its fullest potential. The suction cup action is actuated by a lever arm which is operatively connected to the suction cup rod. This device can further contain a splash guard which will eliminate splashing or spilling caused by the rapid plunger action.
