  • Patent number: 4291742
    Abstract: The invention relates to a method and apparatus for obtaining an ingot wherein elastic oscillations are directed on metal being crystallized over a broad frequency range and at high intensity in the form of powerful pulses generated by a high-voltage spark discharge in liquid. One form of the apparatus of the invention comprises a discharge chamber filled with liquid in contact with a mould or with melt. The discharge chamber is provided with a system of electrodes connected to a pulse current generator. Upon feeding high-voltage current pulses to the electrodes, high pressure, impulse flows, cavitation and surge waves are built-up in the liquid resulting in the appearance of elastic oscillations acting on the molten metal.

  • Patent number: 4285224
    Abstract: An electric pulse tube expander for a bed with a vertical guide and horizontal guides mounted thereon. An electrode is movably mounted on the vertical guide. Mounted on the horizontal guides are drives for moving the electrode in vertical and horizontal planes. The drives include electric motors, reducers and mechanisms for setting the distance of movement of the electrode. Each of the mechanisms comprises a reducer whose drive gear is kinematically coupled to a lead screw, whereas its driven gear has an arm affixed to, and extending from, its shaft. The arm periodically interacts with a limit switch of a tube expander control system.
