Abstract: A soft substance gasket material preferably made of a metal reinforced fiber mat is impregnated with a silicone impregnating agent comprising a mixture of a polysiloxane having reactive hydrogen groups such as a polyhydrogen siloxane, an addition cross-linking polysiloxane such as a methyl vinyl siloxane, and cross-linking catalysts, preferably in the form of only one organic metal compound. In spite of having small quantities of addition cross-linking polysiloxane and cross-linking catalysts, the impregnated seals are not tacky after cross-linking, they are easy and inexpensive to manufacture, and they evidence improved functional characteristics such as improved resistance to hot media, temperature and aging when compared with seals impregnated with only one type of polysiloxane.

Abstract: An information recording medium includes a substrate having first and second sides. A layer of photoresist is deposited on the first side of the substrate. This layer of photoresist has a selected thickness and defines an area of openings therein such that the first side of the substrate is exposed at the openings, the openings being distributed in a pattern indicative of selected stored information.

Abstract: A spray shield for a faceplate panel having a viewing widow and an integral peripheral panel sidewall which terminates in a seal land includes a gasket of a low durometer high temperature elastomer which envelopes the seal land for preventing pull-through of a spray coating. The shield and the gasket prevent the spray coating from being deposited on a predetermined portion of an interior sidewall portion of the panel and on the seal land. Since the gasket prevents pull-through of the spray coating, none of the spray coating is deposited on the exterior surface of the panel.
