  • Patent number: 5419033
    Abstract: A method in which the wires from the heads on an actuator arm can be positioned and attached to the arm electronics automatically. A loadspring manufacturing assembly has a pair of wire carrying and positioning tails and a disposable portion. The disposable portion and the wire carrying and positioning tails each have pegs for controlling the position of the wire and for allowing twisting of the wire pairs for purposes of noise suppression. The wires are positioned about the pegs and twisted. The wires are then bonded to the loadspring assembly. A portion of the wire carrying tail has a window or opening therein. The wires are fanned out and spaced apart as they pass across the window. The wire carrying portion also has a living hinge. A portion of the wire carrying tail which includes a latching window which latches a peg is moved about the hinge and positioned at about a right angle to the loadspring. The disposable portion and the unused tail are removed.

  • Patent number: 4317980
    Abstract: A method and apparatus are shown for controlling the cycle of a resistance welding device by providing compensation for variations in the effective weld area and the primary input electric power variations through a composite correction applied to the length of the squeeze time cycle portion prior to the weld cycle portion when weld current is activated. Compensation is made for secondary weld current variations by altering the length of the hold cycle, during which electrode contact is maintained with the work subsequent to the weld cycle portion, to change the amount of heat quenched from the weld zone. Further by sensing the condition wherein either the electrical input or the motive power that drives the movable electrode is beyond correctable limits, the welding cycle is aborted when suitable quality welds cannot be made.
