A portable drum machine for producing electrodeposited copper foil continuously is disclosed. The drum machine has an electrolyte supply system which supplies copper ions at a substantially uniform composition. The machine produces copper foil that may be taken directly to a foil surface treatment system or rolled for treatment later. The result is a readily replicable, highly standardized computer-aided design stored on discs or in computer memory. A drum of readily fabricated design is made of three different metals designed for minimum voltage loss and uniform current distribution. The machine also incorporates a dimensionally stable anode precision-produced by ring-rolling concentric with the drum. Low-loss electrical connections are symmetrically configured. A spray reactor is provided for dissolving scrap metal or foil scrap. The system can be electrically and chemically isolated from other machines. There is also apparatus for thoroughly washing the foil with electrolyte and water. A directly coupled positive drum drive is coordinated with a controlled-tension windup of foil in roll form.

Apparatus for making metal foil

An article and method for bonding a high temperature resistant polymeric material to an aluminum base substrate is disclosed using an alkaline bath comprising an alkali metal chromic salt, an alkali metal carbonate and a water soluble salt of an alkaline earth metal selected from the group consisting of calcium, barium, strontium and mixtures thereof.

A method for bonding a high temperature resistant polymeric material to an aluminum base substrate is disclosed using an alkaline bath comprising an alkali metal salt, an alkali metal carbonate and a water soluble salt of an alkaline earth metal selected from the group consisting of calcium, barium, strontium and mixtures thereof.

An inorganic composition adapted for use in bonding a high temperature resistant polymeric material to an aluminum base substrate is provided. The composition is obtained by reacting a first inorganic compound containing chromium and oxygen with a second inorganic compound containing at least one element selected from the group consisting essentially of calcium, barium and strontium to form a reaction product containing chromium, oxygen and at least one element selected from the group essentially consisting of calcium, barium and strontium. A method of bonding a high temperature resistant polymeric material to an aluminum base substrate using the above composition is also provided.
