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.

Abstract: A molding machine for molding material is provided. The machine includes a cavity to be filled with molten metal and a conduit system leading to the cavity, thus forming a system of interconnected hollow spaces. At least one pressure member is moveable in at least part of the conduit system. A centrifugal pump in fluid communication with a reservoir of molten metal is provided, the pump providing molten metal to the hollow space receiving the at least one pressure member.

Abstract: A fitting includes a body and a subassembly to connect to the body. The subassembly includes a gland, a nut and one or more collets captured between gland and nut. An O-ring is seated in a recess in one of the body and the gland. The gland can receive a conduit and the nut serves both to compress the collets around the conduit and to press the gland against the body. The nut may be retracted to a position where the subassembly may be moved transverse to the axis of the conduit, gland and nut without first retracting the gland and conduit axially.

Abstract: A fitting comprises a body with a generally flat first face, a gland with a generally flat second face, and a collet assembly adapted to be squeezed onto the outside of the conduit. A nut surrounds the gland and is adapted to engage the body, to force the first and second faces into sealing engagement with each other and to force the collet assembly into sealing engagement with a conduit and with an internal passage in the gland. When the nut is an advanced position, it engages the body, transmitting an axially compressive force to the first collet and pressing the forward end face of the gland against the rear end face of the body. When the nut is a retracted position, it has its forward end face no farther forward than the plane of the forward end face of the gland.

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.

The door facings have adjacently disposed inner surfaces, and each of the opposing sides of the window frame is secured to an associated inner surface about the associated opening. A window is secured within the window frame. The present invention is also related to a method of making the door, and a panel component resulting from the disclosed door making process.

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.

Abstract: A releasable fastening assembly for attachment of a boot to a snowboard comprises a mounting member which, in use, is fixed to the snowboard, and a support member which is rotatable relative to the mounting member.
