Patent number: 8827670Abstract: A dual platen molding machine for constructing a plurality of pre-insulated structural panels is disclosed that includes multiple safety features. The molding machine produces one or more panels that may include one or more c-channels or profiles embedded in expandable polystyrene (EPS) foam to provide structural integrity to the panels, and resulting wall. A chase may be formed horizontally in the panels to provide a wiring conduit through the panel. The molding machine is electrically operated to control the movement of a movable molding portion when closed upon a stationary molding portion. Steam may be controlled to fuse insulating material such as expandable polystyrene (EPS) in cavities formed between the movable mold and the stationary mold. No hydraulics is required to operate the dual platen molding machine, thus improving operating and maintenance costs. Moreover, steam hoses may be avoided, thereby improving overall safety.Type: GrantFiled: July 12, 2011Date of Patent: September 9, 2014Assignee: Radva CorporationInventor: Luther I. Dickens

Patent number: 8555585Abstract: An apparatus and method for constructing pre-insulated structural panels is disclosed that has a tongue and groove assembly arrangement. Each panel may include one or more c-channels or profiles embedded in expandable polystyrene (EPS) foam to provide structural integrity to the panels, and resulting wall. The panels may be covered with siding, stucco, or similar materials. A chase may be formed horizontally in the panels to provide a wiring conduit through the panel. The panel may also provide when assembled, a vertical chase formed between the mated panels along the length of the panel for wiring. Acoustical properties may be formed in the surface of the EPS portions to provided added acoustical damping measures.Type: GrantFiled: November 2, 2012Date of Patent: October 15, 2013Assignee: RADVA CorporationInventor: Luther I.

Patent number: 4953334Abstract: A low cost insulating panel for covering walls of existing structures has an expanded cellular core having complementary stepped side edges of differing width to define depressions in a combination of two panels. The panel has thin flat reinforcing strips along side edges extending upon a front face of the panel and therefrom into the stepped configurations at most to come in contact in the depression formed by two mating panels without extending to a back face of any panel.Type: GrantFiled: October 29, 1987Date of Patent: September 4, 1990Assignee: RADVA CorporationInventor: Luther I. Dickens

Patent number: 4653718Abstract: An improved molding structure for producing a building panel or the like of expanded cellular core material having reinforcing strips flush with surfaces thereof and including one or more indentations or depressions having reinforcing elements extending therein and anchored within the core.Type: GrantFiled: December 19, 1984Date of Patent: March 31, 1987Assignee: Radva CorporationInventor: Luther I. Dickens

Patent number: 4284447Abstract: A method of forming a panel structure useful in building construction and the like includes the steps of heating a heat expandable plastic in a separable mold having a cavity with the configuration of the resultant panel to form a panel core and adhering thin reinforcing strips to the front and back surfaces of the core. Control over the dimensions and configuration of the panel is obtained by adhering the strips to the core in the mold while applying heat thereto whereby core shrinkage is minimized. The strips may be adhered to the core during initial heating of the plastic material to form the core or may be adhered to the core in the mold subsequent to core formation.Type: GrantFiled: May 18, 1979Date of Patent: August 18, 1981Inventors: Luther I. Dickens, William C. Nanny

Patent number: 4241555Abstract: A building panel has an expanded plastic core with thin reinforcing strips bonded to front and back surfaces of the core, at least along the edges thereof, and may have a wire grid attached in offset relation to one surface thereof for receiving a material such as concrete. The panel is manufactured by a process of expanding a plastic material in a mold by the application of heat to form a core, removing the core from the mold, placing thin reinforcing strips on front and back surfaces of the core with an adhesive system between strips and core, returning the core to the mold and heating the interior of the mold to bond the strips to the core and achieve dimensional stability during molding.Type: GrantFiled: May 30, 1978Date of Patent: December 30, 1980Assignee: Radva Plastics CorporationInventors: Luther I. Dickens, William C. Nanny

Patent number: 4240557Abstract: A molded polystyrene foam wedge-shaped merchandise support with a plurality of reinforcing ribs with at least one transfer hole in each rib. The top, edges and sides of the support may be covered by a protective covering. The protective covering may be a thermoplastic sheet, such as an acrylonitrile-butadiene-styrene polymer, or a laminated fiberboard.Type: GrantFiled: December 28, 1978Date of Patent: December 23, 1980Assignee: The Mead CorporationInventor: Luther I. Dickens

Patent number: 4144296Abstract: A process for molding in situ a polystyrene foam structure with a relatively rigid thermoplastic sheet covering a portion of the surface of the polystyrene foam. The thermoplastic sheet is cut and folded into proper shape and a heat-activated adhesive applied to the inside surface. The folded sheet is inserted into the female cavity of a mold which is then closed. Expandable polystyrene is injected into the interior of the folded sheet and heated to expand the polystyrene against the sheet and the adhesive is heat-activated to bond the sheet and polystyrene.Type: GrantFiled: June 23, 1976Date of Patent: March 13, 1979Assignee: The Mead CorporationInventor: Luther I. Dickens

Patent number: 4094110Abstract: A system of constructing buildings by connecting together expanded plastic panels with reinforcing strips bonded thereto and wire mesh attached to the exterior surfaces thereof upon a foundation with at least a portion of the panels having a curved configuration to maximize structural strength of the combination of panels. Concrete is applied to the exterior of the combined panels with the wire mesh then forming reinforcing in the resultant concrete wall upon the panels and the interior is coated with plaster to form a low cost structure with very good insulating properties.Type: GrantFiled: March 24, 1976Date of Patent: June 13, 1978Assignee: Radva Plastics CorporationInventors: Luther I.
