A door, method of making a door, and stack of doors includes providing a door having front and back skins that have differing, but complementary profiles, one for the front side of the door and one for the back side of the door where each allows and fits onto the other, while still providing direct contact in the stile and rail zones of the door permitting conventional door layup practices.

An inner door assembly for a drum washing machine includes an inner door internal shell formed of plastic and including a rim portion and a projecting portion projecting from the rim portion; and an inner door external shell formed of metal and including a rim portion and a projecting portion corresponding to the rim portion and the projecting portion of the inner door internal shell, wherein the inner door external shell is combined not to be separated from the inner door internal shell.

Apparatus allowing ventilation through a ventilation shaft to an underground ventilation duct fluidly communicating through the ventilation shaft to an atmospheric opening of the shaft and on threat of flooding operable to prevent downward flow of surface water into the ventilation duct includes support sidewalls fitting in the shaft providing a ventilation passage between support top and bottom openings and a suspension member supported on opposed lateral sidewalls proximate the top opening holding one or more hinge connected panels that manually release to rotationally close the passage and are manually rotationally liftable to a home position allowing ventilation. A panel drain automatically closes when the panel is raised to home position. A releasable latching system between panel and a suspension member holder catches rising panels to hold them in home position. The suspension member may include end keys received in keyed supports so a specific panel faces a specific sidewall.

Apparatus allowing ventilation through a ventilation shaft to an underground ventilation duct fluidly communicating through the ventilation shaft to an atmospheric opening of the shaft and on threat of flooding operable to prevent downward flow of surface water into the underground ventilation duct includes one or more hinged panels closing a ventilation passage between the top and bottom of a support fitting in the shaft to prevent flooding. The panels have handles on their topside and pivotable arms on their underside and are liftable to an upright home position allowing ventilation, using tools to reach through grating covering openings on the shaft and lift the panel handles and after the panels are partially lifted, using reach tools to engage and lift the arms to press them again support sidewalls to exert lateral force on underside of the panels to complete upward rotation to the home position.

A door system for a doorway to a gas-tight chamber includes a door panel that selectively moves between a closed position for sealing a doorway of a chamber and an open position for permitting access to an interior of the chamber through the doorway. The door panel has an inner side generally facing the interior of the chamber when the door panel is in the closed position. A door panel track is connected to the inner side of the door panel. The door panel track selectively cooperates with an interior track of the chamber to facilitate movement of a cart between the door panel to the interior of the chamber.

A molded article comprising a food container top, and a method for producing same, is disclosed. The method includes providing a mold for forming the molded article, wherein the mold defines a frame, a utensil located substantially coplanar with the frame and a frangible link between the frame and the utensil, providing an in-mold lidding film having a heat activatable lower surface, positioning the in-mold lidding film adjacent to an interior molding surface of the mold, molding the molded article from a heated thermoplastic resin contained within the mold, whereby the heated thermoplastic resin contacts a perimeter of the heat-activatable lower surface of the in-mold lidding film, and the perimeter of the heat-activatable lower surface of the in-mold lidding film is molded to the frame of the article such that the in-mold lidding film hermetically seals an opening defined by the frame.

A radio frequency (RF) and acoustic shielded door that has a door leaf with an acoustically insulated core. The perimeter of the door leaf is banded with a conductive contact channel, which is electro-mechanically bonded to a shielding media that is applied to the door face. A conductive angled contact is mechanically attached at a bottom of the door. An acoustic or radio frequency gasket seal assembly is attached to the door frame, and the gasket seal assembly is adjustable so that a complete seal can be formed around the head, jamb and sill of the door.

A panel drain automatically closes when the panel is raised to home position so it is already closed when the panel is released to rotationally close the passage.
