A diffusing apparatus is adapted for vertically adjustable relation with a fog tower. A separate second corrosive fluid is emitted from plural outlets spaced approximately 45.degree. apart along the exterior of the diffusing apparatus. The outlets direct the second corrosive fluid in a generally planar direction substantially perpendicular to the longitudinal axis of the fog tower for optimum uniform dispersion either alone or intermixing with a first corrosive fluid emitted from the fog tower.

Corrosion test cabinet contaminant mixing apparatus

A metal finishing barrel having a body section 10 extending between a pair of end caps 12, that includes a sidewall comprising a plurality of wall sections 14, 16 joined edge-to-edge. In one embodiment, the wall sections are formed from a single, continuous sheet member 44, bent along lines of weakness in the form of V-shaped notches 46 that each define a relatively thin, hinge-like bridging section 46a that connects adjacent wall sections. External locking ribs 50 coengage edge portions of adjacent wall sections to maintain the sheet member in its assembled configuration. Alternately, individual wall panels 14', 16' are fabricated with beveled edge surfaces 46' and are secured in edge confronting engagement by the external locking ribs. In an alternate embodiment, an internal locking rib is employed that also serves as a tumbling rib and coengages locking grooves formed on inside surfaces of edge portions of each wall section.

Metal finishing barrel

A plating barrel having a number of plating electrodes coupled to a constant source of electrical potential outside the barrel and connected to a metal plate which rotates with the barrel. A spring biases a non-rotating conductor against the plate inside the barrel to provide a low resistance path to the constant source outside the barrel. A number of seals prevent plating solution from reaching the contact between plate and conductor to avoid corrosion and/or plating of the contact area.
