Abstract: Substantially transparent compositions that block electric-arc energy. A process of making the compositions comprise blending an IR/optical dye with a substrate material and subjecting the blend to curing conditions. Products manufactured from the composition ablate upon impact of electric-arc energy.

Abstract: An apparatus for maintaining the eyes of an animal, such as a dog or cat, closed during surgery to keep the surface of the eyes moist. The apparatus includes a collar, a head pad connected to the collar and positioned between an animals ears on its forehead, and a pair of straps also connected to the collar positioned to extend from beneath the animal's chin over the animal's eyes and to be fastened to the head pad. The head pad and straps cooperate to pinch or force together loose skin above and below the eyes to close the eyelids and prevent drying out thereof. A lead line extending from the collar attaches to a non-movable structure so that when the animal awakens, the movement of the animal pulls the collar loose from around the neck.
