Abstract: A reliable mechanical and electrical connection is formed between a slotted rivet and an insulated ground wire using a minimum number of manual steps. The slotted rivet head has two spaced, opposed, semi-frustoconical sections that define a slot between them. The slotted rivet is placed and properly aligned in a coil frame, and the ground wires are placed into the slot. The rivet head is then deformed by an orbital riveter to capture a portion of the insulated wire within the rivet head. A resistive welder engages the rivet head to vaporize the insulation from the captured wire portion without touching the wire. The resulting terminal assembly has a unique design in which the deformed rivet head is substantially flat.

Abstract: A speed control for an electric golf car providing sequential changing between a plurality of speeds such that the golf car must accelerate through fixed speeds for predetermined times prior to reaching a full speed. A foot pedal actuable by the operator controls a plurality of magnetic reed switches. The reed switches in turn control a timing circuit for generating a plurality of motor drive signals in succession at predetermined times. The motor drive signals actuate relay coils for applying power to the golf car motor.
