摘要:
A combination heated, vacuum and pressure press is provided for facilitating the transfer of a substance from a workpiece to which it is weakly adhered to a substrate to which it is more permanently adhered by means of a heat-activated thermosetting adhesive. The press consists of a platen having vacuum passages therein with a flexible blanket overlying the platen so that it may be drawn tightly to the platen upon application of the vacuum and a cover in the form of a dome sealingly engaging the platen and forming a chamber thereover, the cover having an internal heating element and the press having means to pressurize the interior of the chamber formed between the platen and the cover so that positive pressure can be exerted on the flexible blanket while the interior of the dome is at the same time heated to assure perfect transfer of a substance from a workpiece to a substrate underneath the blanket.

A METHOD AND DEVICE ARE PROVIDED FOR THE PRECISION ELECTRO DEPOSTION OF METALS BY ELECTROFORMING. THE ELECTROFORMED PRODUCT CAN BE MADE WITH METAL DEPOSITION THICKNESS CONTROLLED WITHIN $10% ON DEPOSITS AS THIN AS 0.005 MM. THE METHOD COMPRISES DIRECTING AND CONTROLLING THE FLOW OF METAL IONS FROM THE ANODE ION DOOR TO THE CATHODE ION RECEPTOR BY MEANS OF A UNIQUE ION FLOW DIRECTING SYSTEM COMPRISING AN ANODE AND A DIELECTRIC NONPOROUS PERFORATE ION-FLOW DIRECTING DEVICE WHICH PROXIMATELY AND SPACEDLY SURROUNDS THE ANODE, THEREBY ALLOWING THE FLOW OF THE ELECTROLYTIC SOLUTION ABOUT THE ENTIRE AREA OF THE ANODE DIRECTING SUCH FLOW OF ION RICH ELECTROLYTE IN A RELATIVELY UNDIFUSED PATH TO THE CATHODE.
IN ANOTHER ASPECT, THE INVENTION DISCLOSES A PECISION ELECTRICAL CIRUCIT MADE BY THE UTILIZATION OF THE PROCESS INDICATED ABOVE.
