Abstract: A dynamic sealing structure for pressure vessels used in microwave assisted chemistry is disclosed. The structure includes a cylindrical vessel liner and a removable liner cap, each formed of a microwave transparent material. The liner has a circular mouth with a lip formed of respective first and second beveled edges, with the first beveled edge forming an interior edge of the circular mouth and the second beveled edge forming an exterior edge of the circular mouth. The cap includes respective interior and exterior faces, with a sleeve depending from the interior face and having a circumference that engages the interior surface of the vessel liner for being urged under pressure against the interior surface of the vessel liner. The interior face of the cap comprising a circular channel outward of the sleeve and having a circumference that engages the lip of the vessel liner, and with the channel comprising two beveled edges that respectively engage both beveled edges of the lip of the liner.

Abstract: A method and apparatus for reinforcing and stabilizing a structure formed of stacked blocks, such as a pier used in a building's foundation. The method and apparatus employ brackets to bracket the edges of the structure and transiting members to transit the body of the structure. Stabilizing members engage with the transiting members. The stabilizing members are then tightened against the brackets thereby compressing, reinforcing and stabilizing the structure.

Abstract: A method and apparatus are disclosed for forming a resin-impregnated fiber web that is particularly suitable for use in reinforced plastic composites and printed circuit board applications. The method includes the steps of drawing machine direction yarns from multiple spools contained in creels arranged around a hollow cylinder; passing machine direction yarns from the creels through a circular reed; pulling machine direction yarns the length of the hollow cylinder's outer surface in a longitudinal direction; controlling the application of an uncured or partially cured thermoset or thermoplastic resin to the yarns as they travel the length of the hollow cylinder; winding cross-direction yarns around the periphery of the hollow cylinder (i.e., on top of the machine direction yarns) thereby forming a web; heating and cooling the resulting web; and finally collecting the web on a roll.
