摘要： A molten material can be heated, melted and directly solidified in a single vessel. Induction heating and melting of the molten material is achieved by magnetically coupling the field produced by current flow in a plurality of induction coils surrounding the vessel with either the molten material in the vessel, or a susceptor surrounding molten material in the vessel. Current flow is selectively removed from the plurality of induction coils, and a cooling medium surrounding the vessel, such as water flowing through hollow induction coils, solidifies the molten metal into a highly purified crystalline solid.

摘要： An apparatus and method for controlling the pour of molten metal into individuals molds. The apparatus comprises a reservoir for holding molten metal to be poured into at least one mold having a sprue and a mold gating system, and a flow control device operatively associated with the reservoir for controlling the flow of molten metal from the reservoir into the mold. A sensor continuously senses the image of the surface of the molten metal in the mold and generates image area information representative of the surface area of the metal relative to the surface of the mold. A sampling circuit repetitively samples the image area information during a pour and generates sampled image area information at a preselected sampling rate. A comparator repetitively compares the sampled image area information to a preselected reference area value and generates a difference value representative of the difference between the image area information and the reference area value. Control apparatus responsive to the difference value generates a control signal to the flow control device for controlling the flow of molten metal to minimize the difference.

摘要： An apparatus and process are provided for bonding of materials by induction heating of an electrically conductive material upon which a second material is bonded. The electrically conductive material is induction heated between a first induction heating plate, and the combination of a frame and a second induction heating plate that is disposed within the frame. The second induction heating plate is removed from the surface of the electrically conductive sheet, while the frame continues to hold the electrically conductive sheet flat, and the second material, in liquid form, is poured into the interior opening of the frame in which the second induction heating plate was originally placed. The liquid material solidifies and bonds to the electrically conductive sheet to produce a bonded product. A continuous sheet of an electrically conductive material may be bonded to a continuous sheet of a second material by pressing them together and moving the pressed together materials through an induction coil to inductively heat the electrically conductive material and bond it with the second material.

摘要： Power is controllably supplied to a resistive load. Power is passed from a power supply through a selectably operable switch directly to the resistive load and simultaneously to an energy storage device in parallel with the load. After a predetermined interval, the energy storage means causes the switch to open, thus causing the energy stored in the energy storage means to be transferred to the load. The switch is periodically closed according to a predetermined frequency.

摘要： The instant invention is directed to a stopper rod spatial control mechanism for use in combination with a bottom discharge holding reservoir for molten metal having a nozzle. The mechanism comprises a base, an outer tube and an inner tube. The outer tube has a longitudinal axis which is perpendicular to the base. The outer tube is swingably mounted about an axis parallel to and spaced away from the longitudinal axis. The inner tube is telescopically mounted within the outer tube. The inner tube is reciprocally movable along the longitudinal axis and is rotatable about the longitudinal axis. A servomotor is mounted at a lower end of the outer tube. A ball screw is connected to and rotated by the motor. A ball nut is affixed to the inner tube and cooperates with the ball screw. A boom having a first end and a second end is affixed to the inner tube adjacent its first end and rotates with the inner tube about the longitudinal axis. A stopper rod depends from the second end of the boom. A brake is affixed to the base and cooperates with the boom. The stopper rod is aligned with the nozzle by the combined movements of rotating the inner tube about the longitudinal axis and swinging the outer tube about the axis parallel to said longitudinal axis. Once the stopper rod is aligned, the position of the stopper rod is fixed by the brake. Thereafter, reciprocal movement of the stopper rod above the nozzle is controlled by the actuation of the servomotor.

摘要： An apparatus and process are provided for controlling the heating or melting of an electrically conductive material. Power is selectively directed between coil sections surrounding different zones of the material by changing the output frequency of the power supply to the coil sections. Coil sections comprise at least one active coil section, which is connected to the output of the power supply, and at least one passive coil section, which is not connected to the power supply, but is connected in parallel with a tuning capacitor so that the at least one passive coil section operates at a resonant frequency and the output frequency of the power supply is changed so that the induced power in the at least one passive coil section changes as the frequency is changed.
