    Abstract: An audio-visual system for providing correlated audio and visual presentations from audio-visual slides in a sequence corresponding to a branched learning format. Upon an operator selecting a presented response choice, a projected program containing first indicia providing a binary number indicating the number of steps and second indicia indicating the direction which the slide magazine should be stepped to be in position for presenting the next slide, is sensed and the binary number is stored in a register. The magazine is stepped in the indicated direction; and the number of steps taken are counted and compared to the binary number stored in the register. When the compared counts are equal, the stepping of the magazine is stopped.

    Abstract: Methods of providing diffusing risers on a fresnel lens die having a plurality of optical facets, wherein adjacent optical facets are separated by a riser, the method including the steps of depositing a difflusing layer on the plurality of optical facets and the risers, and selectively removing the diffusing layer from the plurality of optical facets, wherein the diffusing layer remains substantially intact on the risers. The diffusing layer can be deposited in an electrolyte bath substantially free of grain refiners.

    Abstract: There is provided a cellulosic-based fiber granule with added non self-associating particulates or fibers. The resulting granule is free-flowing with a densified outer surface and is capable of removing substantially all oil from a flat surface such as a floor. The granule is also capable of being incinerated by being formed substantially of organic materials. Cellulosic plant fibers form at least 10 percent up to 99 percent of the granule. There is also provided a method for forming the incineratable oil an absorbent, free-flowing granules.

    Abstract: A metal-coated multilayer mirror having high reflectivity and high specularity. The mirror comprises a multilayered polymer film and a reflective metal layer. The multilayered polymer film preferably comprises layers of a crystalline, semi-crystalline, or liquid crystalline material, such as a naphthalene dicarboxylic acid polyester, having an average thickness of not more than 0.5 microns and layers of a second polymer having an average thickness of not more than 0.5 microns. Preferably, the layers of semi-crystalline naphthalene dicarboxylic acid polyester have a positive stress optical coefficient. The reflective metal layer comprises a metal selected from the group consisting of silver, gold, aluminum, nickel, copper, and titanium, with silver and aluminum being particularly preferred. The metal-coated multilayer mirrors are useful in applications requiring broad bandwidth reflection, high specularity, low manufacturing costs, and high reflectivity.
