A plug assembly for use in a process for manufacturing an insulated register box has a body having a bottom and at least one side wall extending upwardly from the bottom, a rotatable element at the bottom of the body, and an actuator connected to the rotatable element and positioned above the rotatable element. The rotatable element is adapted to seal an end of a duct in an interior of the box of the insulated register box. The rotatable element is movable between an installation position and a sealing position. The actuator is cooperative with the rotatable element so as to move the rotatable element between the installation position and the sealing position.

The present invention provides articles and methods related to insulation panels made from aerogels, and specifically polyimide based aerogels. Such insulation panels have a wide variety of applications, including specifically in aerospace applications.

A plug apparatus for sealing an interior of a duct for use in a process for forming an insulated register box has a frame, a shaft extending outwardly of the of the frame, and a plurality of layers of flexible material radiating outwardly of the shaft adjacent to an end of the shaft opposite the frame. The plurality of layers of flexible material are adapted to have an outer periphery bearing against an interior surface of the duct. Each layer of flexible material has an outer diameter greater than an inner diameter of the duct. The flexible material is formed of a neoprene material. The frame is affixed to a support surface having an opening therein. The opening is adapted to receive an outer diameter of the duct therein.

A system and method for primarily erecting curvilinear buildings using a plurality of interconnected structural tubes/sandwich panels is provided. Fabricating structural tubing comprises: connecting a fibrous and flexible lining to an inner surface of a flexible outer membrane, wherein the lining is saturated in a curable material that forms into a solid foam material when cured; and curing the curable material. Fabricating a sandwich panel comprises: connecting a first fibrous and flexible lining to an inner surface of a first flexible outer membrane, wherein the first lining is saturated in a curable material that forms into a solid foam when cured; connecting a second fibrous and flexible lining to an inner surface of a second flexible outer membrane, wherein the second lining is saturated in a curable material that forms into a solid foam when cured; and curing the curable material of the first lining and second linings.

A register box for HVAC installations has a body with a plurality of side panels arranged in a generally rectangular or square configuration and a wall extending across the rectangular configuration, a duct opening through the wall so as to communicate with an interior of the body, and an expandable foam polymeric material affixed to an inner side of the side panels. The wall has a surface extending from the opening of the duct to the side panels. The expandable foam polymeric material is affixed to the surface of the wall. The expandable polymeric material is polyurethane.

A molded product includes a body including a flat part and a projection protruding from the flat part, a design member including a design surface, and an adhesive member sticking the design member to the body. The adhesive member includes a buffer portion formed by cutting off a part of the adhesive member at a position corresponding at least to the projection. Thus, the adhesive member negates differences in level on the body, allowing the design surface to be smooth.

A heat-insulating housing (21) includes: a wall body; and an open-cell resin body (4) of thermosetting resin with which a heat-insulating space formed by the wall body is filled by integral foaming, the open-cell resin body including: a plurality of cells (47); a cell film portion (42); a cell skeleton portion (43); a first through-hole (44) formed so as to extend through the cell film portion; and a second through-hole (45) formed so as to extend through the cell skeleton portion, wherein the plurality of cells communicate with one another through the first through-hole and the second through-hole.

Insulated wall and roof sheathing systems for use in building construction designed to provide moisture permeable wall panels that protect from bulk water, excess air, and thermal transfer.

A foam structural material includes a first core material and a reinforcing material. The first core material has a first portion of a linear groove part formed along an edge of the first core material. The reinforcing material has a first side fitted to the first portion of the linear groove part. The first portion of the linear groove part includes a first engagement plane. The first engagement plane is engaged with the reinforcing material and has one or a plurality of projections formed thereon.

A layered cushion that may be fully disassembled for easy cleaning is disclosed herein. The sleep system is durable and fire retardant. The layered cushion may include a foam layer, a layer of void cells, and a cover. The foam permits fluids to move freely there through and contours to a user's body to maximize comfort and reduce interface pressure. The reticulated foam layer resists compression set and thermosetting. The layer of void cells also permits fluids to move freely there through and provide additional support to the user's body. The individual void cells of the void cell layer are perforated to allow the transmission of fluids there through. The cover couples the other layers together to form the layered cushion and prevents the layers from deteriorating. The cover is removable to permit cleaning each of the layers independently.
