Abstract: A blending chamber for blending fluids used to dry particulate matter has a chamber body with a first inlet opening, a second inlet opening, a third inlet opening, an outlet opening and a blending section. The blending section is arranged in a flow direction downstream of the first, second and third inlet openings, and upstream of the outlet opening. Fluids entering the first, second and third inlet openings are blended together in the blending section before exiting through the outlet opening. The bending chamber may be used to dry sawdust in a system that does not require a dedicated heat source.

Abstract: An electrical charge dissipation device is interposed between two sections of a fluid flow line and is operative to dissipate electrical charges present therein in order to reduce corrosion. The charge dissipation device comprises an elongated tubular portion having a central longitudinal axis and including a surrounding sidewall forming an interior passage therefor. Opposite first and second ends are adapted to interconnect respectively with the two sections whereby the tubular portion is interposed therebetween such that fluid flows through the interior passageway. A charge collector is disposed in the interior passageway in electrical isolation from each of the two sections and includes a plurality of longitudinally spaced apart conductors organized in a selected array. These conductors operate to conduct electrical charges contained in the fluid exteriorly of the tubular portion whereby they may be dissipated to an electrical ground.

Abstract: The present invention relates to a method and apparatus for electrically isolating the pump unit for a well, such as an oil well and the like. More particularly, the present method and apparatus electrically isolates the pump unit from electrical currents that are generated within a well casing when a fluid is pumped from the well.
