Abstract: A filtration device for filtering air for use with a fuel vapor recovery system. According to one aspect, the device includes a housing defining a chamber having a rotational axis an upper end and a lower end, a cap closes the housing and includes at least one generally helical passageway helically extending generally toward the lower end of the chamber and includes at least one air inlet. According to another aspect, the device includes a non-circular filter element disposed between an air inlet and an air outlet.

Abstract: A dust separation device for separating contaminants from a fluid. The device may include at least one spiral fin disposed in an inlet tube for directing at least a portion of the contaminants in a spiral flow, and a deflector for deflecting at least a portion of the contaminants into a into a collection chamber. A fuel system for an internal combustion engine and a method of separating contaminants from a fluid are also provided.

Abstract: A starting plate is provided for electro slag remelting apparatus in which only a small surface area of the ingot bottom in the area adjacent the ingot perimeter is welded to the starting plate. The starting plate is either an annular disc in which the innermost surface area engages the ingot outer periphery or is an annular disc which is not in engagement with the ingot but which includes a plurality of spaced recesses to accommodate metal tabs that extend into the mold cavity to engage the ingot bottom along portions of its outer periphery. The starter plate is normally made of a steel or inexpensive ferrous alloy.
