摘要： The specification and drawings disclose a method and apparatus for forming dish-shaped metal elements through the use of a combined fluid pressure and sheet tensioning process. The disclosed method is particularly intended for forming dish-shpaed sheet metal elements having a length substantially greater than their width and includes applying a longitudinal tension to the sheet while permitting the lateral edges to move toward one another substantially unconstrained while the fulid pressure acts to bow the sheet. The disclosed apparatus includes a flexible frame of generally eliptical shape which clamps to the edge of the sheet. The frame is arranged so that as the sheet bows outwardly, the lateral sides of the frame are pulled inwardly driving the ends of the frame apart.

摘要： The specification and drawings disclose a load bearing structure and method for forming the same. In particular, the drawings show a catamaran-type sailboat including a pair of hulls having thin aluminum outer skin. The rigging, sails and deck are supported from rigid frame or load distributing members positioned within the hulls and spaced from their outer skin. Plastic is foamed in place in the hulls and encloses the frame members. The plastic foam bonds the frame to the skin of the hulls and serves as the primary media for transmitting the reaction loads from the deck and sails.
