A method for producing an electroforming mandrel is disclosed wherein a continuous conductive film is deposited onto a substrate, and a photoresist is deposited over the conductive film, exposed and developed to form a pattern on the conductive film whereupon a metal element is electroformed.

Electroforming elements

A laminated glass product is produced without an autoclave by a technique that applies an excess of liquid plasticizer to each upwardly facing interfacial surface of an assembly to be laminated in various stages of assembly while said upwardly facing surface is exposed to ensure the absence of air bubbles in the ultimate laminated product.

Low pressure lamination of safety glass

Transparent, electroconductive articles produced by cathode sputtering on refractory substrates, a metal from the group of elements having an atomic number from 48 to 51 and mixtures thereof, and preferably a controlled proportion of tin to indium, in a low pressure atmosphere containing a controlled amount of oxygen at a controlled substrate temperature within a temperature range of 400.degree. F. to a temperature at which the substrate becomes distorted or detrimentally affected, usually at or above 600.degree. F.
