Apparatus for horizontally plating one surface of conductive sheet with a metal or metal alloy. The apparatus includes an electrolyte holding tank, a horizontally disposed enclosed electrolyte conduit having extended inlet and outlet portions, a variable speed pump for passing electrolyte from the holding tank through the conduit and a rectifier for supplying electrical current. The holding tank includes means for dissipation of entrapped gas bubbles generated during metal deposition or caused by aeration. The conduit has a horizontal opening including an insoluble anode within the opening for defining a plating cell. The anode is positioned parallel to the axis of the conduit and in alignment with the opening. The plating cell includes means for supporting the sheet above the opening. The inlet and outlet portions of the conduit are positioned in-line with the plating cell. The inlet portion has a cross sectional area greater than the cross sectional area of the plating cell and is positioned sufficiently upstream of the plating cell so that electrolyte is stabilized when flowing between the anode and the sheet. Only the bottom surface of the sheet is exposed to electrolyte flowing through the conduit.

Electrolytic plating one surface of conductive sheet

Interlocked channel section panels having an interlocking joint wherein the male and female members are provided with deformable hook portions. During field assembly the female member overlies the male member with the outer surface of the corresponding upstanding members and upper portions of the male and female members adapted to mate throughout their lengths, and the deformable flange hook portions of the male and female members are capable of being reformed so as to conform intimately to effect continuous, positive interlocking of male and female ribs. A clip connector, including a body portion tightly sandwiched between associated corresponding upstanding members, upper portions and deformable flange hook portions of the sidewalls of the coupled panels, and a foot at the other end of the body portion of the clip connector anchored to a supporting member and fastening the connector along with the coupled panels to the supporting member, is also provided.
