  • Ultrasonically welding a conductor wire to an electrical terminal
    Patent number: 4817814
    Abstract: The invention relates to an apparatus and method for ultrasonically welding a conductor wire to an electrical terminal. The terminal has a channel portion for receiving the conductor wire. The electrical terminal with the wire therein is confined adjacent the welding tip whereby movement of the welding tip into the channel portion presses the conductor wire against the electrical terminal and welds it thereto.

  • Variably-weighted ultrasonic welding horn
    Patent number: 4749437
    Abstract: Apparatus for the ultrasonic sealing of plastic or metal containers which include a source of ultrasonic wave energy, an ultrasonic welding horn and an anvil. The ultrasonic welding horn is provided with means to adjust and make uniform the amplitude of vibration of the wave energy transmitted by the horn. This is accomplished by attaching weights of varying magnitude to the horn, thus assuring a uniform amplitude of the ultrasonic vibration across the face of the worksurface of the horn, to effect a uniform bond on a workpiece.
