Thermal insulation structures include a polymer foam layer adhered to a multi-layer sheet having a non-cellular layer of a heat-resistant thermoplastic and a second non-cellular layer of a polylactide resin. The polylactide resin is a surprisingly good barrier to the diffusion of atmospheric gases into the foam layer and of blowing agents out of the foam layer. Accordingly, the diffusion of atmospheric gases and blowing agents is retarded substantially. This greatly reduces the loss of thermal insulation capacity of the structure due to the replacement of the blowing agent with atmospheric gases. The multi- layer sheet exhibits excellent thermal stability, even when the polylactide in the polylactide layer is highly amorphous.

A method of making a gasket track for a gasket is provided. A first section of a c-shaped channel comprising from 50% to 75% of the c-shaped channel of a first plastic material is formed. A second section of a c-shaped channel comprising from 25% to 50% of the c-shaped channel of a second plastic material is formed. The first section is joined together with the second section to form all of the c-shaped channel. The c-shaped channel has a circular cross section that forms at least 65% of an ellipse.

An access door for a combine harvester includes a body having a top, a bottom, a first side, and a second side. The body includes a height defined between the top and the bottom and a width defined between the first side and the second side. A plurality of ribs is integrally formed in the body for adding rigidity thereto, and a deflector is integrally formed with the body and protrudes therefrom. The deflector has a top surface and a width that is substantially the same as the width of the body. The body is defined within a first plane and the top surface is defined within a second plane such that the second plane is disposed at an angle less than 90? from the first plane.

The process for the manufacture of windows/doors (1), characterized by the fact that it comprises the following steps: providing at least one inner panel (2) for windows/doors; providing a plurality of plastic profiled elements (3) for windows/doors, each of the profiled elements (3) comprising at least two areas to seal (5), coupleable to the areas to seal (5) of the other profiled elements (3), and at least one longitudinal slot (6), in which a respective perimeter side (4) of the inner panel (2) is insertable; performing a step of mechanical machining by chip removal on at least one of the areas to seal (5); heating the areas to seal (5); coupling the heated areas to seal (5) to one another by pressing the profiled elements (3) one against the other to maintain the areas to seal (5) in mutual contact and define the frame for windows/doors, the coupling taking place with the inner panel (2) inserted in the longitudinal slots (6) to define a window/door (1) which is composed by the frame and by the inner panel (2) contained in the frame.

A fire rated door includes a core, a first decorative panel and a second decorative panel. The core includes: (a) a fire resistant center panel having a bottom, a top, a first side, a second side, a first end and a second end, wherein the fire resistant center panel is made of a first fire resistant material, and (b) an extruded fire resistant border attached to the first side, the second side, the first end and the second end of the fire resistant center panel, wherein the extruded fire resistant border is made of a second fire resistant material having a higher density than the first fire resistant material. The first decorative panel is attached to the top of the fire resistant center panel and the extruded fire resistant border. The second decorative panel is attached to the bottom of the fire resistant center panel and the extruded fire resistant border.

A method of manufacturing a door skin and a fuselage wall having a doorway and a member extending into the doorway for abutting the door includes placing a first sheet of uncured composite material on a mold plate to define the door and fuselage skin, disposing an insert over the first sheet overlapping a desired periphery of the door, placing a second sheet of uncured composite material on a peripheral portion of the insert and over the first sheet adjacent the peripheral portion of the insert to form the member, curing the sheets and bonding the sheets together adjacent the insert during the cure, removing the insert from between the sheets after cure, and separating the door skin from the wall skin after cure by moving a cutting tool through the first sheet and without penetrating the second sheet around the desired periphery of the door. An assembly for manufacturing the door skin and a fuselage wall is also discussed.

An insulated door panel comprises a shell having spaced first and second exterior panels and frame members adjacent edges of the panels, a plurality of stiffeners in a shell interior portion extending along a length or width of the panels, and a hardenable insulation material creating a bond between the exterior panels, stiffeners, and frame members in the shell interior portion. The stiffeners comprise a thermally non-conductive fiber reinforced polymer. The hardenable insulation fills substantially all of the space between the adjacent exterior panels, stiffeners, and frame members. The door panel also comprises end cap members composed of thermoplastic polycarbonate material, and has openings therein to receive the ends of the stiffeners.

The present invention is directed to a door facing blank having a first major surface with a design element formed therein, and an opposite second major surface. At least three longitudinally extending spaced stile receiving areas are disposed on the second major surface. Two of the stile receiving areas define a first width, and three of the stile receiving areas define a second width greater than the first width. The door facing blank may be trimmed to form a door facing having a selected width. A method of forming a door facing blank, and a mold press for forming a door facing blank are also disclosed.

Provided are a structure and a method of forming a structure that includes a core made, at least in part, of a rice hull composition. The rice hull composition including a combination of separate, unground rice hulls; ground rice hulls; and a rice hull powder, that each have a different particle size. A polymeric binder, such as a recycled plastic polymeric binder binds the separated unground rice hulls, the ground rice hulls and the rice hull powder together.

A mesh to flexible screen frame laminator includes a first table with a horizontal surface and an alignment fence, a second table that is lower than the first table and a first pair of selectively driven heater rollers which are shiftable between a raised position and a lowered position relative to the first table. A cradle is located adjacent the first table and above the second table and at least a portion of the cradle is shiftable between a raised position and a lowered position, the raised position being substantially coplanar with the first table. A second pair of selectively driven heater rollers is shiftable between a raised position and a lowered position relative to the second table and is oriented transversely to the first pair of heater rollers. A third table is located adjacent the second table and at a height substantially coplanar with the second table.
