Title: Method of partially enamelling articles of stainless steel
IPC: C23D3/00
Filed: 1978-09-04
Abstract: A method of partially enamelling articles of stainless steel in which areas of the articles are left un-enamelled comprises degreasing at least the areas to be enamelled and pretreating with an adhesion improving treatment prior to covering with enamel, firing the enamel and polishing the enamel-free surfaces. The adhesion improving treatment involves applying a layer of nickel, cobalt or copper then electroplating with an adhesion incurring layer of iron. A mean thickness of an electroplated iron layer in the range of from 5 mu  to 20 mu  is preferred. The iron layer is improved by picking before enamelling, either electrolytically or chemically. Removal of oxides, scales and intermediate layers from the enamel free areas after firing is performed by pickling in a sulphuric acid and phosphoric acid liquor. Improved removal is achieved by first anodically electrolytically pickling the article, then chemically pickling it and then alternately anodically and cathodically electrolytically pickling the article.

Title: Selective plating
IPC: C25D5/08
Filed: 1979-07-30
Abstract: The invention relates to selective plating, especially selective gold plating of Printed Circuit Board Edge Connectors and similar components where the amount of gold plated can be reduced by depositing different depths of gold on different areas of the selectively plated parts of the components. Advantageously, the whole area to be plated is plated to a desired thickness and then part of said area is selectively plated to an increased thickness. Alternatively, a total gold strike is first applied, followed by a selective plating of part of the area to be plated, followed by a plating of the whole area to be plated or the different thicknesses are obtained by preferentially directing electroplating solution to the area to be plated to the greatest thickness.
