  • Method and apparatus for arc welding
    Patent number: 4447703
    Abstract: An arc welding process is provided with a preheating step in which a consumable wire electrode is heated prior to insertion into the electrode stick-out region. This is accomplished by the circulation of current from a preheating power supply through a segment of the wire. Both gas-metal and gas-tungsten arc welding processes are disclosed, along with apparatus used in these processes.

  • Ultrasonic excitation of underwater torpedoes for enhancing maneuverability, speed and targeting accuracy
    Patent number: 4429652
    Abstract: For enhancing the maneuverability, speed, survivalbility, and targeting accuracy of a torpedo moving below the surface of a body of water, ultrasonic vibrations are set-up at the exterior of the torpedo hull, using controlled piezoelectric crystals to generate the vibrations in the 5-50 KHZ and 5-30 KW frequency and power ranges. Ways are disclosed for operating the piezoelectric crystals to steer the hull without need for mechanically moving parts such as flaps or fins.
