Abstract: Methods of making metal patterns on flexible substrates are provided. Releasable solid layer is selectively formed on a patterned surface of the flexible substrate by applying a liquid solution thereon. Metal patterns on the flexible substrate can be formed by removing the releasable solid layer after metallization. In some cases, the releasable solid layer can be transferred from the patterned surface to a transfer layer where the metal patterns are formed.

Abstract: Shaped microcellular structures having substantially non-cellular skins are produced from reactive liquid polymer systems incorporating thermoplastic microspheres containing volatile materials such as low boiling point halogenated or non-halogenated organic materials. Use of thermoplastic microspheres encapsulating such volatile materials facilitates the removal of the shaped foamed structure from molds, eliminating the need for release agents. Various products based on this process, such as bathroom fixtures, bicycle and wheel chair tires, shoe soles, and automotive parts, are provided.

Abstract: A snap lock handle is disclosed herein for releasable connecting onto the top and bottom ridges of a conventional can which includes a U-shaped member having a central hand gripping portion terminating at its opposite ends in connection elements outwardly cantilevered normal to the gripping portion. The ends of the connection elements are provided with transverse channels for insertably receiving the ridges of the can. The channels are defined by opposite legs wherein an outer leg is of elongated length so as to engage with the top and bottom of the can while the inner leg is flat or flush in one instance and hooked in the other so as to nest in the usual groove at the top of the can.
