  • Publication number: 20040033386
    Abstract: A high strength dual phase cold rolled steel having controlled amounts of carbon, manganese, and molybdenum is used as a starting material in a hot-dip zinc coating process to manufacture a high strength dual phase cold rolled steel having a conventional galvanized or galvannealed coating applied to at least one surface thereof, the zinc coated steel product having a uniform coating of zinc in spite of the high manganese content of the steel.

  • Patent number: 6689489
    Abstract: A method of coating of steel products such as plate and sheet using an aluminum-zinc coating alloy includes modifying the coating bath with a particulate compound constituent in effective amounts to control the spangle facet size of the coated product, improve tension bend rust stain performance, and improve coated product paintability. Constituents include borides such as titanium boride and aluminum borides, carbides such as titanium carbide, and aluminides such as titanium aluminide. The method produces a coated steel product that does not require temper rolling for painting.

  • Patent number: 6660220
    Abstract: The invention is directed to a dynamic control system that maintains an inert gas feed at a constant target gas flow rate sufficient to prevent or reduce alumina or alloy plugging within a slide gate discharge opening. The dynamic control system includes a gas feed line extending between an inert gas supply and the slide gate discharge passageway, a gas flow regulator, a pressure gauge; and a gas feed flow control that detects an amount of incoming inert gas lost through leaks in the system and adjusts the gas flow regulator in response to the detected amount of incoming gas flow loss so that the adjusted incoming gas feed continues to deliver the target inert gas flow rate to the discharge passageway.

  • Patent number: 6635313
    Abstract: A method of coating dual phase high strength cold rolled steel having controlled amounts of carbon, manganese, and molybdenum is used as a starting material in a galvanizing/galvannealing process. Conditions in a multi-zone furnace of the galvanizing line can be controlled in a conventional manner while still effectively coating the high strength steel. A dual phase high strength steel product is made having a uniform coating of zinc in spite of the high manganese content of the steel.

  • Patent number: 5810008
    Abstract: The present invention provides a system and method for visualizing internal images of an anatomical body. Internal images of the body are acquired by an ultrasound imaging transducer. The position and orientation of the ultrasound imaging transducer is tracked in a frame of reference by a spatial determinator. The position of the images in the frame of reference is determined by calibrating the ultrasound imaging transducer to produce a vector position of the images with respect to a fixed point on the transducer. This vector position can then be added to the position and orientation of the fixed point of the transducer in the frame of reference determined by the spatial determinator. The position and orientation of a medical instrument used on the patient are also tracked in the frame of reference by spatial determinators. The position and orientation of the instrument is mapped onto the position and orientation of the images.
