Abstract: Paint is sprayed in a line onto a fiber glass mat just prior to the mat being impregnated with hot asphalt. The temperature of the asphalt causes the paint solvent to flash, the process of which prevents the asphalt from displacing the pigment, leaving the paint pigment in place in the body of the mat. A number of such lines may be formed on the mat at predetermined spaced locations to serve as installation guide lines for the roofer.

Abstract: Apparatus for applying a coating to semiconductor chips mounted within apertures in a dielectric film. The film containing the semiconductor chips and input-output connectors is fed from a reel past an applicator for applying the coating on one side of the chips. After passing through a curing chamber, the film passes about a substantially square sprocket so as to reverse the direction of travel. The sprocket is of such a dimension that the film bends on a line between each individual chip or a selected group of chips. The strip then passes by another applicator for coating the other side of the chips. After passing through the curing chamber, including a substantially square sprocket, the film is wound on a driven sprocket. The coating may be a silicone composition, an epoxy resin, or a urethane composition.

Abstract: Coating a ceramic substrate on a second major surface while avoiding damage to a coating comprising a matured enamel frit previously applied to the first major surface. After coating one major surface with an enamel frit composition and maturing its frit component thereon, the substrate is oriented with its matured enamel frit coating facing downward and coated on its second major surface with one or more frit compositions that must be heated to an elevated temperature at which the previously matured frit coating would be prone to damage on contacting a solid member. This invention avoids such damage by supporting said matured frit on a gas bed in spaced relation to any solid member capable of demaging the enamel frit component during the portion of the heating and cooling cycle needed to mature the frit coating on the second major surface when the temperature of the substrate is elevated to a minimum temperature approaching that at which the previously matured frit would be prone to such damage.
