  • Patent number: 12076785
    Abstract: A method for delivering molten metal to a shot sleeve of a casting machine from a molten metal furnace. A molten metal pump is positioned within the furnace. The pump includes a molten metal outlet in fluid communication with the shot sleeve. A shaft and impeller or screw assembly of the pump is selectively rotated to introduce molten metal to the shot sleeve in a predetermined quantity. The predetermined quantity is determined by a controller that receives a signal from a trigger mechanism associated with the molten metal outlet.

  • Patent number: 10415884
    Abstract: A method of fluxing or degassing a molten metal residing as a bath in a furnace. The bath of molten metal includes a bath surface height and the method provides at least one rotating impeller in the molten metal bath to initiate a flow of the molten metal. The flow in the molten metal results in elevating a portion of the molten metal above the bath surface height where at least one of a fluxing agent and an inert gas is introduced into the elevated portion of the molten metal.

  • Publication number: 20120253696
    Abstract: This invention relates to methods and apparatus for inspecting surfaces such as plates or pipe walls of magnetisable material using magnetic reluctance to gain data about the surfaces being inspected. In a preferred method, a magnetic circuit that passes through at least a magnetising unit and a portion of the surface to be inspected is created. The magnetic reluctance in the magnetic circuit is measured at one or more positions in the circuit. At least one of the measured magnetic reluctance values is incorporated into one or more algorithms. The result of the or each algorithm is recorded or displayed for each magnetic reluctance reading in association with information concerning the position of the or each magnetic reluctance reading on the surface.

  • Patent number: 6809271
    Abstract: The apparatus includes two somewhat convex shoes clampable along the adjacent sides of a pair of rails for engagement by the peripheries of wheel flanges so that the wheels are raised just clear of the rails, a load-sensing device at the highest portion of each shoe, and load-indicating means connected to the devices. The apparatus is sectional, the shoes being urged apart into rigidly clamped positions by two struts separable from the shoes to facilitate portability. Two spaced-apart support members are secured to each shoe to embrace its outer and lower faces, each support member being vertically adjustable relative to the shoe to suit different heights of rails. The shoes have replaceable wear-strips.
