Abstract: A modular glazing system having several members, each member having one or more keyways or keys that permit the members to be connected. A preferred embodiment has four fundamental shapes: a base longitudinal member, an expander A, an expander B and a screen sash member. The base longitudinal member has a glazing channel, through which supplemental or primary glazing material is inserted. Along one side wall of the base longitudinal member is a keyway formed to interlock with a key from another piece. At right angles to the first keyway in the base longitudinal member, and disposed along a bottom wall of the base longitudinal member is another keyway, similarly shaped. The base longitudinal member also has an interior aperture through which an L-shaped connector is inserted to form corners. An expander A, shaped generally like the letter H, has two keys, one located on either side of the middle bar of the "letter" H. An expander B has only one key, depending downwardly from the middle bar of the "letter" H.

Abstract: A color separation imaging process employing an imaging monolayer of particles comprising a resin carrier containing color-photosensitive material, and a solid-form dye material. The monolayer is exposed between two members, one transparent, under the influence of an electric field. A color separation image is formed upon splitting the sandwich, and the image is then subjected to thermal energy in order to imbibe the dye into a suitable substrate, thus producing a brilliantly-amplified color image.
