Latest Patents

Costello's latest patents focus on the circuitry for the electrolytic coloring of anodized aluminum surfaces. The first patent describes a process and circuitry that utilizes a controllable, asymmetrical, and substantially sinusoidal alternating current (a.c.) voltage. This voltage is applied to a coloring bath containing at least one metal salt, which is essential for coloring the aluminum article. The process allows for independent adjustment of the amplitude levels of both the positive and negative half waves of the a.c. voltage, enhancing the precision of the coloring process.

The second patent reiterates the same innovative approach, emphasizing the ability to vary and adjust the amplitude levels independently. This flexibility in controlling the a.c. voltage is crucial for achieving the desired coloring effects on anodized aluminum surfaces.
