Abstract: The present invention relates to an article comprising: a pair of substrates comprising a thermoplastic; a holographic recording medium positioned between the substrates such that the holographic recording medium has at least one exposed area; and an environmental barrier seal protecting the at least one exposed area from environmental degradants; wherein the environmental barrier seal comprises: an inner layer adhered to at least one of the substrates and comprising a thermally meltable adhesive; an outer layer comprising a moisture impervious plastic; and an intermediate layer positioned between the inner and outer layers and comprising an moisture and oxygen impervious metallic foil. The present invention also provides a process for forming such an article.

Abstract: Apparatus for insulating a connector, mechanically joined to one end of an electrical conductor, by positioning a radially expandable resilient insulating sleeve, having an inside diameter in its non-expanded condition smaller than the largest cross-sectional dimension of the connector, about the connector. The connector includes one end portion mechanically joined to the conductor and a terminal end portion for connection to another electrical component. The apparatus of the present invention includes expansion means for expanding the sleeve sufficiently to receive the connector and holding means for maintaining the sleeve in its expanded condition and for permitting the connector to be received, terminal end portion first, into the expanded sleeve.
