Abstract: A wire injector apparatus for impelling wire or injecting wire is provided. The wire injector has a motorized pulley system connected to a drive wheels for moving the wire laterally through the apparatus. Further, upper and lower idler wheels are arranged about the drive wheels to engage the wire with the drive wheels. A clamp connects the upper idler wheels to the lower idler wheels such that a single actuated lever can control and position multiple upper and/or lower idler wheels. Wire line paths for moving the wire are provided intermediate to the drive wheels and the idler wheels. The arrangement of the components of the wire injector allows for customizing the number of idler wheels and drive wheels to, in turn, provide any number of wire line paths for impelling or injecting any number of wires.

Abstract: A desulfurization apparatus which employs first and second separate independently movable spaced apart lances (10, 12), each lance having a single conduit (22) through which the desulfurization materials may flow from feed vessels (40, 42, 44, 46) into the molten iron in a ladle (16). First and second independently operable raising and lowering apparatus (28, 30) are provided, the first raising and lowering apparatus (28) being connected to the first lance (10), and the second raising and lowering apparatus (30) being connected to the second lance. Each of the first and second raising and lowering apparatus (28,30) is capable of moving the associated lance (10, 12) from between a raised position where the lower end of the associated lance is spaced above the surface of the molten iron in the ladle and a lowered position where the lower end of the associated lance is spaced within the ladle at a proper location for desulfurization of the molten iron.

Abstract: An orifice valve assembly which may be utilized to control the flow of a fluent material, such as powdered magnesium, propelled by gas under pressure, the valve controlling the flow in a linear manner.The valve includes a valve body having first and second adjacent concentric bores, the first bore being of a larger diameter than the second bore, and a cross-bore intersecting the first bore, the cross-bore having a cylindrical portion which intersects the first bore and frusto-conical inlet and outlet portions to either side of the cylindrical portion.
