20110045117 | Method of preparing a molded article - A method of forming a shaped thermoplastic sheet includes providing a mold apparatus that includes, a first mold portion having an interior mold surface having a plurality of perforations and a perimeter edge. The mold apparatus further includes at least one sheet retainer having an upper surface having a plurality of perforations and a longitudinal axis that is oriented along at least a portion of the perimeter edge of the first mold portion. Each sheet retainer is reversibly and controllably: positionable along an x-, y- and/or z-axis relative to the perimeter edge; and rotatable around its longitudinal axis, toward and/or away from the perimeter edge. A heated thermoplastic sheet is formed and contacted (while at a thermoformable temperature) with the interior surface of the first mold portion and the exterior surfaces of the tubular sheet retainers. Reduced pressure is drawn through the perforations of the sheet retainers thereby retaining a portion of the heated thermoplastic sheet thereon. The sheet retainers are moved along the x-, y- and/or z-axes, and optionally rotated, with the sheet retained thereon, relative to the perimeter edge. Reduced pressure is drawn through the perforations of the interior mold surface, thereby drawing the heated thermoplastic sheet into intimate contour matching contact. The heated thermoplastic sheet is allowed to cool, and a shaped thermoplastic sheet retaining the contour of interior mold surface is formed. A sheet molding apparatus is also described. | 02-24-2011 |
20110045118 | Method of preparing a molded article - A method of preparing a molded article, and more particularly to a method of forming a shaped thermoplastic sheet. The method includes providing a mold apparatus that includes a first mold portion with a contoured and perforated interior mold surface, and a perimeter edge. The mold apparatus also includes a frame that surrounds at least a portion of the perimeter edge of the first mold portion. At least one sheet retainer resides on the upper surface of the frame. Each sheet retainer includes a clamp portion that faces towards the perimeter edge of the first mold portion, and which includes a reversibly closeable clamp member which defines in part a clamp interior. Each sheet retainer is independently, reversibly and laterally attached to the upper surface of the frame, such that each clamp portion is reversibly and laterally positionable relative to the perimeter edge of the first mold portion. In the method of the present invention, each sheet retainer, with a first portion of a heated thermoplastic sheet retained within the clamp portion thereof, is independently, reversibly and laterally moved towards and/or away from the perimeter edge of the first mold portion. Independent reversible and lateral positioning of each sheet retainer provides control over the thickness of the heated thermoplastic sheet that is contacted with the interior mold surface of the first mold portion during the molding process. Accordingly, such independent lateral positioning of each sheet retainer provides control over the thickness of various portions of the final molded article. | 02-24-2011 |
20140013695 | MODULAR BUILDING PANEL - An improved modular building panel and system for building construction is disclosed. The improved modular building panel comprises a novel honeycomb or lattice core comprising multiple layers of corrugated, preferably metal, components mechanically connected by any means known in the art, but which may be chemical bonding. External cladding layers comprising a novel cement mix comprising, in a preferred embodiment, Portland cement, silica sand, perlite, glass beads, and water, in combination with the honeycomb structure, provide a lightweight, highly durable, low-cost, projectile resistant, highly insulating, water, mold and mildew resistant, wind resistant novel modular wall system which is adapted for use in commercial, residential, and other construction and which provides superior security to the user. The modular building panel and system of the invention may be utilized for walls, roofs, floors, bridges, or other structures. | 01-16-2014 |
