Abstract: Sheet metal having a partially cured organic thermosetting coating thereon and method of forming drawn and ironed seamless containers therefrom.

Abstract: Articles exhibiting a micropattern carried by a surface of a support, typically microdevices comprising a micropattern of a functional material on or in a substrate of a dissimilar material, are produced by a method employing a microsubstrate comprising a substrate base, a protein layer which comprises at least a compressed monolayer of a denatured non-fibrous protein on the base, and a masking film overlying the protein layer, the material of the masking film being such as to be modified by radiant energy so as to be removable from the protein layer where irradiated. The method is flexible in the sense that it is possible to proceed via either a positive or a negative of the desired micropattern and to build a more extensive, or more complex, micropattern from an initial relatively simple micropattern.

Abstract: Micropattern devices, such as electronic microcircuits, are produced by establishing on a substrate base a film of resist material, such as a polymeric film, containing dispersed therethrough a substantial proportion of an enzyme and then producing a pattern of a metal by reactions depending upon presence of the enzyme.
