Abstract: A system for generating electricity for powering an electric or hybrid motor vehicle uses a fan which is driven by the air flow created by the motion of the vehicle. In the event that the fan is unable to generate sufficient electricity, a controller operates an auxiliary gas powered motor for the generation of electricity for powering the electric or hybrid motor vehicle.

Abstract: The master jaws in a three jaw chuck are located and maintained in position by a spacer having two plates which are located adjacent one another along edges which are inclined approximately 7.degree. from the vertical. One plate is generally rectangular. The other plate is generally trapezoidal. Sliding the plates along the inclined edges positions one edge of the rectangular plate against one of the master jaws and the two edges of the generally trapezoidal plate against the other two master jaws. The relative movement of the plates changes the position of the outer edges of the plates which allows for the master jaws to make contact with the plates at different positions to allow for positioning of the soft jaws for machining.
