International Classification:

E04B 1/18

US Classification:

Abstract:

“Environmental Empty Fiber Cement Form” is a fiber cement form which includes two fiber cement panel and/or boards, rigid insulation (optional), vapor barriers, concrete adhesives, steel rebar (optional), cell spacers are made of the same fiber cement board or any compatible material like metal, plastics, etc. The cell spacers vary in depth, height and thickness. The forms have attached electrical connections (optional). The two exterior fiber cement boards are joined together using the appropriate adhesive/glue. The cell spacers are also joined to the exterior board/panel with adhesive/glue producing empty cells of different height and depth as needed for the chosen application.These cells/chambers can be filled with any type of mixture, compounds and/or a combination of both like but not limited to: concrete, sand, plastics, polymers, cast, insulation material, etc. Once the “Environmental Empty Fiber Cement Form” is placed over a floor slap, foundation, ditch, etc and the whole form is filled while the mixture/compound inside the cells/chamber has the necessary curing time then the form becomes a solid wall and/or barrier. The optional steel rebar that can be placed inside the cells/chambers will enhance the form/mold strength. The optional electrical connections placed inside the empty cells/chambers will also enhance the utilization of the form as a wall for any construction like houses, buildings, barriers, etc.The other advantage of this “Environmental Empty Fiber Cement Form” that once it is filled with any mixture and become a solid wall/barrier does not requires the removing of the exterior boards like in the conventional construction forms. Neither requires plastering for a smooth/final finish since the exterior side of the fiber cement boards are flat, plain and smooth.

Abstract:

Thermally assisted processes for removing internal defects in glass ceramic products, specifically electrical shorts formed in a substrate during product fabrication, are set forth. According to one aspect of the invention, a method for repairing shorts between metallic conductors located within in a glass ceramic product, such as an electronic substrate, comprises the steps of (a) pre-conditioning the glass to resist cracking from the generation of heat by any shorts melt down current subsequently applied to said conductors; and (b) subsequently applying a melt down current to said conductors to repair any short located therebetween. The aforestated method minimizes the potential for glass damage resulting from defect repair activity and optimizes defect repair yield. Further aspects of the invention relate to processes that involve preconditioning conductors located within glass ceramic products to assure that molten metal from a short melt down juncture draws back toward parent conductor lines, and processes that are used to effectively control the thermal gradient in the areas within glass ceramic products where shorts repair activity is to take place.
