Abstract:
Methods for degassing and for removing impurities from molten metals are disclosed. These methods can include operating an ultrasonic device in a molten metal bath, and adding a purging gas into the molten metal bath through the tip of the ultrasonic device.
Abstract:
A plurality of individual elements are imparted with reverse axial twist and collectively twisted into a multi-element assembly. Each individual element has an axial twist direction in an opposite direction from the axial twist direction of the collective multi-element assembly. The reverse axial torsion in the assembly tightly binds the plurality elements in the assembly to resist separation.
Abstract:
The present invention includes a cable (12) having reduced surface friction and the method of manufacture thereof including the steps in which a conductor wire (14) is coated with a First plastic material (17), coated with a second plastic material and the coated conductor wire (14) then cooled, and includes a step in which a lubricating material (19) is applied to the surface of the cooled, coated cable (12).

The present invention includes a cable (12) having reduced surface friction and the method of manufacture thereof including the steps in which a conductor wire (14) is coated with a first plastic material and with a mixture of a second plastic material (17) and lubricating material (19) and the coated conductor wire (12) is cooled. The cable (12) includes at least one conductor core (14) and a least two coatings of plastic material and incorporates a lubricating material (19) in and/or on the outer layer of plastic material (17). The equipment (11) for manufacturing of the electrical cable (12) includes a reel (13) for supplying a conductor wire (14) to an extruding head (15), which is connected to tanks (16 & 18) containing plastic material (17) and lubricating material (19) for coating the conducting wire (14), and a reel (21) for taking up the cable (12).
Abstract:
Tape shaped superconducting wires are covered with a stabilizing metal and are wound on a flexible former (13). The wires are laid at a bending strain of not more than 0.2 %. A number of wires are laid in a side-by-side manner to form a first layer (15). Tape shaped superconduncting wires are laid on top of the first layer in a side-by-side manner to form a second layer. The former may be metal, plastic, reinformed plastic, polymer or a composite and provides flexibility to the superconducting wires and the cable formed therewith.
Abstract:
Ultrasonic probes containing a plurality of gas delivery channels are disclosed, as well as ultrasonic probes containing recessed areas near the tip of the probe. Ultrasonic devices containing these probes, and methods for molten metal degassing using these ultrasonic devices, also are disclosed.
Abstract:
A continuous flexible bus may be provided. The continuous flexible bus may comprise a plurality of flexible conductors that may be metal clad. A device, such as a switch for example, may be connected to the continuous flexible bus. In order to connect the device to the continuous flexible bus, at least one piercing connector may be used. The at least one piercing connector may be configured to pierce one of the plurality of flexible metal clad conductors. Once the one of the plurality of flexible metal clad conductors is pierced, the at least one piercing connector may cause an electrical connection between an electrical conductor in the pierced one of the plurality of flexible metal clad conductors and the switch.
Abstract:
Devices may be in contact with molten metals such as copper, for example. The devices may include, but are not limited to, a die used for producing articles made from the molten metal, a sensor for determining an amount of a dissolved gas in the molten metal, or an ultrasonic device for reducing gas content (e.g., hydrogen) in the molten metal. Niobium may be used as a protective barrier for the devices when they are exposed to the molten metals.
Abstract:
The mixture of plastic (17) and lubricating material (19) being coated on the electrical conductive wire or fiber optic wire by extruding head (15) to form an electrical cable or optical cable (12) having a surface with reduced coefficient of friction.
Abstract:
Tape-shaped superconducting wires (15) include a covering of a stabilizing metal and are wound on a flexible former (13). The superconducting wires are laid on the former (13) at a bending strain of not more than 0.2%. The wires (15) are laid side-by-side to form a first layer. A prescribed number of tape-shaped superconducting wires are laid on top of the first layer side-by-side to form a second layer. The former may be made of a metal, plastic, reinforced plastic, polymer, or a composite and imparts flexibility to the cable.
