oven. The sheet substrate is conveyed on a roller conveyor within the oven and the semiconductor material whose main layer is cadmium telluride is deposited on an upwardly facing surface of the substrate by each deposition station from a location within the oven above the roller conveyor. A cooling station rapidly cools the substrate after deposition of the semiconductor material thereon to strengthen the glass sheet of the substrate. 5536488
INDIRECTLY HEATED THERMOCHEMICAL REACTOR PROCESSES Durai-Swamy Mansour Momtaz N; Kanda-Swamy; Warren David W Columbia, MD, UNITED STATES assigned to Manufacturing and Technology Conversion Resonant tubes of a pulse combustor are immersed in a bed of solid particles in a reaction zone to provide indirect heat from the pulsating combustion gases to the solid particles of the bed. The bed is maintained in an agitated state by a gas or vapor flowing through the bed. Reactant materials are introduced into the agitated bed and undergo reaction at enhanced rates resulting from heat transfer coefficients at least about twice as high as those of steady flow combustors and an intense acoustic pressure level propagated from the pulsating combustor into the reaction zone. The apparatus is useful, for example, to steam reform heavy hydrocarbons and to gasify carbonaceous material, including biomass and black liquor to produce low relatively combustible gas at temperatures, with steam being utilized as the bed fluidizing medium. Black liquor gasification, utilizing sodium carbonate as bed solids, results in liquor energy and chemical content recovery without smelt production.

5537990 SOLAR WATER HEATING SYSTEM Lee Jia-Shing (TAIWAN)
Ping Tung Hsien, CHINA
A solar water heating system includes a water storage tank to which a hot water outlet pipe and a cold water inlet pipe are connected. A solar-collector unit is mounted below the water storage tank. A downcomer pipe connects the water storage tank and the lower portion of the solar-collector unit. A return pipe connects the upper portion of the solar-collector unit and the water storage tank. A tube member is installed in the water storage tank and interconnects the downcomer pipe and the return pipe. The solar-collector unit, the downcomer pipe, the return pipe, and the tube member form a loop that is filled with deionized water.
