Abstract: An example putter presented herein is designed manufactured in a way that allows for a golfer to adjust weight balance of the golf club head by moving respective weights through a toe-side track and a heel-side track on a bottom side of the golf club head. The putter may also be configured with adjustable toe-hang, face material, and loft all in one club, in order to optimize the club for the day's game without having to purchase a new golf club each time one desires to try something new. The putter head can combine a removable, stackable face plate with a continuous range of shaft attachment points to allow a golfer to adjust each factor all in one club.

Abstract: The power pack includes a permanent magnet d.c. motor energizable by a battery and having a rotatable shaft. The shaft is operable to rotate both (1) an alternator for producing a.c. voltage for use by electrical utilization devices and (2) a hydraulic pump for producing pressurized oil for use by hydraulic utilization devices. When a supply of hydraulic pressure is not required, a valve unloads the pump and causes substantially all of the load of the pump to be removed from the motor so as to enable substantially the entire capacity of the motor to be used to drive the alternator.

Abstract: A simple and economical system for operating a dc. motor of the permanent magnet field type from an ac. supply, characterized in that the motor may be driven at an adjustable speed in a forward direction by energization through a controlled half wave rectifier (e.g., SCR) or at a fixed, high speed in the reverse direction by energization through a half wave diode rectifier.

Abstract: The converter includes a dc. motor energizable from a battery and adapted to drive an alternator which produces an ac. output for powering a remote load device. The latter is adapted to be connected to the converter by a three-wire extension cord having a ground wire for grounding the load device. A manually operable switch is located near the output end of the extension cord and is connected across the ground wire and one of the conducting wires of the cord. The motor of the converter may be started by momentarily closing the switch and may be stopped when the switch is next closed momentarily.
