Abstract: A solar-energy siding system is employed by affixing it to an exterior building surface. The system has a transparent siding element, a laminate having at least two spaced-apart ply members, a reflective member having a first orientation substantially between the siding element and the laminate, and a second orientation substantially removed from the area between the siding element and the laminate, and a mechanism for translating the reflective member between the first and the second orientations. The ply members include at least one inner light-absorbing ply member and one outer transparent ply member. The ply members each include a plurality of spacer ribs and the spacer ribs of the inner ply member are disposed crosswise of, and bear against, the spacer ribs of the outer ply member.

Abstract: The present invention relates to the production of hydrogen fluoride dopant source gases for use in the production of conductive coatings on a substrate. More specifically, a fluorocarbon source gas is decomposed in the presence of oxygen to yield HF which is passed to a deposition furnace wherein a fluoride doped metal oxide coated glass substrate is prepared.

Abstract: An improved apparatus for effectively disrupting biological samples contained in cuvettes to which beads have been added. In the apparatus, a special arm/bearing subassembly is driven and oscillated by a motor in a manner to attain cellular disruption of the biological samples without degradation of their cellular components. In the preferred form, the special arm/bearing subassembly has a cam, bearings, and a bearing sleeve which cooperate with a motor drive shaft to rotate a yoke with two arms holding four cuvettes. For increased safety and environmental protection, special sample retainers can be provided to better secure the cuvettes and the arm/bearing subassembly is enclosed in a sample chamber which provides a secondary containment compartment that contain any spillage.
