Abstract: The disclosure relates to composites comprising: a cold-formed decorated or non-decorated glass substrate having first and second major surfaces; a metal or polymeric substrate having first and second major surface; and at least one adhesive located between the glass substrate first major surface and the metal or polymeric substrate first major surface; the glass substrate first and second major surfaces and the metal or polymeric substrate first and second major surfaces defining at least one curvature, the at least one curvature having a bend radius of about 60 mm or greater; wherein the composite maintains adhesion between the glass substrate and the metal or polymeric substrate following physical testing according to a modified GMW3172 environmental and durability test.

Abstract: A repairable pressure relief valve having a valve body that forms an internal fluted surface provides improved field repairability. The internal, fluted surface is adapted to mate with a removal tool. A valve assembly is slidably mounted in the valve housing and slides under excess pressure to vent vapor from a vessel, such as a tank. The valve body has a first seating surface for mating with a second seating surface on the valve assembly when the valve plug is in the closed position. The relief valve has a seal for sealing an interface between the valve plug and the housing and a removable cap mounted proximate to the valve plug for mechanically supporting the seal. The cap can be removed and the seal can be replaced without extensive disassembly of the valve, thereby eliminating the requirement of re-calibration after a repair has been made.
