Abstract: A glittering non-retroreflective sheeting 60 includes an array of cube-corner elements 30 that are arranged in the array such that the sheeting glitters when light is incident thereon. The glitter is in the form of many discrete points of light 68 that tend to blink off and on. The array may be configured such that a dihedral angle .alpha. varies between adjacent cube faces 31 of adjacent cube-corner elements 30 in each groove in one of the groove sets 45, 46, or 47 and such that the base plane 36 are not parallel to each other when the sheeting 60 is laid flat. Preferably, the dihedral angle .alpha. between faces 31 of adjacent cube-corner elements 30 varies in essentially all of the grooves such that the cube-corner elements are randomly tilted throughout the array. The glitter can make the sheeting very useful for aesthetic or decorative applications.

Abstract: A cube-corner retroreflective sheeting 60 includes an array of cube-corner elements 30 that are defined by three sets of intersecting parallel grooves 45, 46, 47. The cube-corner elements 30 are arranged in the array such that the sheeting 60 glitters when exposed to light. The glitter is in the form of many discreet points of light that tend to blink on and off when viewed by the naked eye. The array may be configured such that a dihedral angle .alpha. varies between adjacent cube faces 31 of adjacent cube-corner elements 30 in each groove in one of the groove sets 45, 46, or 47 and such that base planes are not parallel to each other when the sheeting 60 is laid flat. Preferably, the dihedral angle .alpha. between faces 31 of adjacent cube-corner elements 30 varies in essentially all of the grooves such that the cube-corner elements are randomly tilted throughout the array. The sheeting glitters very well under daytime viewing conditions and also to some extent under nighttime or retroreflective conditions.

Abstract: A retroreflective applique is provided that includes a layer of optical lens elements partially embedded in and protruding from a transfer adhesive layer prepared from ingredients comprising a vinyl plastisol and a substantially nonhydrolyzed aminosilane adhesion promoter; wherein the aminosilane adhesion promoter is used in an amount effective to produce an applique capable of:(a) retaining at least about 60% of its initial retroreflectivity after being laminated to 65/35 polyester/cotton blend fabric (100 g/m.sup.2) at about 174.degree. C. and about 2.8 Kg/cm.sup.2 pressure for about 20 seconds and subjected to home laundering conditions five times; and(b) retaining at least about 40% of its initial retroreflectivity after being laminated to 65/35 polyester/cotton blend fabric (100 g/m.sup.2) at about 174.degree. C. and about 2.8 Kg/cm.sup.2 pressure for about 20 seconds and subjected to home laundering conditions twenty-five times.

Abstract: A mold 79 that includes an array of cube-corner elements 80 that are arranged in the array such that a retroreflective cube-corner sheeting 60 that is formed thereon is capable of glittering when light is incident on the sheeting. The array may be defined by three sets of intersecting grooves 25, 26, 27 where each groove set includes two or more generally parallel grooves. At least one groove in at least one of the sets has faces 22 of adjacent cube-corner elements 30a, 30b arranged such that a dihedral angle .alpha. located between adjacent faces varies along the groove(s) in the set.

Abstract: A method of making a glittering cube-corner sheeting, which method includes: (a) providing a first retroreflective sheeting that includes an array of cube-corner elements arranged in a repeating pattern; and (b) exposing the first retroreflective sheeting to heat, pressure, or a combination thereof to produce a second retroreflective sheeting that comprises an array of cube-corner elements that are randomly tilted; or which method may comprise: (a) providing a mold that has a structured surface that includes a multiplicity of cube-comer elements, the cube-corner elements each including a base plane and three faces, the cube-corner elements being arranged such that the base planes do not reside in the same plane when the sheeting is laid flat; and (b) forming a cube-corner sheeting from the mold.

Abstract: At least one compound defined by one of the following formulae: ##STR1## where X represents Cl, Br, ##STR2## NHSO.sub.2 CH.sub.3, ##STR3## or --SCH.sub.3, and n is 1 or 2; andCH.sub.3 SO.sub.2 NHCH.sub.2 CH.sub.2 CN (II)have been administered to animals to improve the efficiency of food utilization by these animals. These compounds can be administered orally by combining the compounds with feed compositions and fed to animals such as ruminants with a developed rumen function as well as other animals that ferment fibrous material and vegetable matter in the cecum or colon. These compounds effect the rumen metabolism to increase the production of propionate relative to other volatile fatty acids, particularly acetate and to inhibit methanogenesis.
