Abstract: A patterned metallized film comprises a transparent or translucent polymeric film coated on one side with a thin coating of metal, with the metal coating and the polymeric film being bonded to each other. The metal coating has a multiplicity of fractures of different sizes distributed throughout the coating in a prescribed pattern so that the reflection of light by the fractured metal coating produces a three-dimensional illusion of the pattern when viewed through said polymeric film. The film may also include a layer of adhesive on the opposite side of the metal coating from the polymeric film, and a paper backing sheet on the opposite side of the adhesive layer from the metal coating. The fractures are preferably formed by heating the metallized film non-uniformly so that selected areas of the film expand and soften at a rate different from the rate at which other areas of said film expand and soften.

Abstract: A method of forming a gasket with an accurately aligned and deposited sealing bead and embossment arrangement. The method comprises providing a deformable gasket body having two spaced apart major surfaces. The next step involves applying a relatively imcompressible sealing material against one of the major surfaces on the gasket body with sufficient pressure and in a manner deforming both of the major surfaces of the gasket body. The deformation of the gasket body defines an embossment comprising a projection extending outwardly from one major surface and a substantially corresponding indentation extending inwardly from the other major surface. Besides creating an embossment, sealing material remains in and fills the indentation to provide support for the embossment. Another step in the process involves curing the sealing material filling the indentation in the gasket body.

Abstract: There is disclosed a method of and apparatus for producing a wear-resistant coating on a thin metallic strip, for example for the manufacture of coating scrapers for paper webs. After preparatory surface treatment the strip is passed longitudinally through a coating zone in which coating material in a molten state is sprayed onto the strip by a coating unit as the strip passes. The wear-resistant coating is built up in steps by the application of several coating layers one on top of the other, each being applied during a respective pass of the strip through the coating zone. The strip speed and the capacity of the coating unit are adjusted in relation to each other so that the heat supplied to the carrier material by each coating layer applied will be so slight in relation to the thermal capacity of the carrier material that the temperature increase in the carrier material does not cause any change in the physical properties of the carrier material.

The cloisonned areas separate the differently colored sections from each other by the formation of slight ridges or low fences into which the differently colored paints can be introduced. After the differently colored paints or other colorings have been introduced into the cloisonned areas and dried, the badge or emblem is polished to expose the ridges or fences separating the cloisonned areas and any other raised areas which it is desired to emphasize. The badge or emblem is then plated with an appropriate plating to cover the raised cloisonned areas and any other raised areas which it is desired to highlight. The resulting badges or emblems have clearly defined brilliantly colored sections and embody remarkable detailed structures.
