Abstract: A ramp with an integral ball deflector is positioned upon the playfield of a pinball game with its entrance approximately level with the playfield. A ball deflector having the shape of a triangle is mounted upon the bottom of the ramp with its widest portion near to the ramp entrance. The hypotenuse of the ball deflector defines a ball deflection surface. When a game ball rolls down the ramp, such as during roll back it is directed away from one of the side walls of the ramp by the ball deflection surface so that it later avoids an undesirable location on the playfield. A bifurcated entrance plate is connected between the ramp entrance and the playfield so that the ball deflector has a minimal effect upon a game ball entering the ramp.

Abstract: A ball diverter located in a ramp or other ball path is moveable between first and second positions and is used to selectively divert a pinball between two paths. The player uses buttons located on the game cabinet to control the position of the diverter and the path travelled by the ball. The mechanism for moving the diverter includes two solenoid coils which are arranged such that the diverter can be held in either the first or second position indefinitely without either solenoid being continuously actuated.

Abstract: Exercising machine having a vaned fanwheel rotatably mounted on a frame in open air and arranged to absorb energy by rotating the vane blades against ambient air. The fanwheel comprises a hub with a plurality of air vanes which are movable in an orbit around the axis of the hub. Each vane comprises a blade having leading and trailing surfaces. In the preferred example shown, each blade is a semi-cylindrical plate mounted with the hollow, concave side comprising the leading surface, and the streamlined, convex side comprising the trailing surface. The vanes are circumferentially spaced apart to substantially eliminate drafting and stagnant wake regions between blades. The coefficient of drag for the concavo/convex vane blades of this invention are substantially twice that obtained by flat plate vane blades conventionally used. Alternative forms of the invention are illustrated with semi-spherical concavo/convex and semi-cylindrical plano/convex blades. All have in common trailing streamlined convex surfaces.
