Abstract: A sign includes fluorescent pigment-containing indicia protected from fading from solar ultraviolet radiation by a transparent, ultraviolet-absorbing shield spaced apart therefrom. An artificial source of ultraviolet radiation is interposed between the indicia and the shield, and permits excitation of the fluorescence for nightime use of the sign.

Abstract: An abrasion resistant reflective exterior marking composition for application to a cementitious substrate, includes a vehicle component having an organic thermoplastic, resinous, film-forming material adapted to form a tenacious bond with the substrate. The composition includes an inorganic aggregate material including a sand component and a glass fibre strand component, a high visibility fluorescent pigment, and a sufficient quantity of an extender for said vehicle so as to render the composition readily applicable to the substrate by brushing, spraying, troweling or the like.

Abstract: A frangible package containing sealant for sealing joints between adjacent construction panels or slabs composed of such materials as concrete, masonry units and curtain wall, includes an elongated tube-like bar having a pair of continuous lines of weakness extending longitudinally along its entire length on opposite sides thereof to enable the bar to be broken apart longitudinally along the lines and thus to release the joint sealant disposed within the hollow interior of the bar, and a pair of end walls for sealing the sealant within the bar. The bar is adapted to be fastened to and extend along the top edge of an expansion joint filler strip, and a pair of external up-turned flanges extending from opposite sides of the bottom portion of the package anchor it to the adjacent slabs after they are positioned on opposite sides of the package and strip so that the top portion of the package may be pulled away readily from its bottom portion leaving it in place to help support the sealant.
