Method of encapsulation and microcapsules produced thereby

Abstract: Microcapsules are prepared by dispersing or dissolving an active component or components in a solid matrix-forming material that has been thermally softened to form an encapsulation composition. The encapsulation composition is injected as an intact stream into a quenching liquid to provide solid microcapsules.

Abrasive article, a process for its manufacture, and a method of using it to reduce a workpiece surface

Abstract: An abrasive article having a sheet-like structure having at least one major surface having deployed thereon a plurality of individual abrasive composites, each abrasive composite comprising a plasticizer and a plurality of abrasive particles dispersed in a binder, wherein said binder is formed by polymerizing a binder precursor and said plasticizer being combined with said binder precursor prior to said polymerizing in an amount of 30 to 70 parts plasticizer per 100 parts by weight of the combined binder precursor and plasticizer. There is also a method of using such as abrasive article to reduce the surface finish of a workpiece and a process of making the abrasive article.

Security card and method for making same

Abstract: A security card comprising a backing, a cover film, and a security image, the security image being located between the backing and the cover film, the backing and the cover film being laminated together without an intermediate adhesive layer, wherein the backing comprises an amorphous copolyester or polyvinyl chloride, and the cover film comprises the other of polyvinyl chloride or an amorphous copolyester. Also, a method for making such security cards.

Termination module for use in an array of modules

Abstract: A module for use in an array for modules for terminating transmission lines and making them readily accessible to connection to distribution lines, the modules comprising small rectangular bases having an end wall supporting a connector, and means affording the tilting movement of each module intermediate the ends of each base to move the end wall from a position aligned with the end walls of other modules to a position affording ready access to the connector of the tilted end wall.
