Abstract: The invention relates to the manufacture of cementitious board, such as gypsum board, faced with paper or other sheets and having an improved accuracy of edge profile. A sheet to be folded at the lateral edges of the board is scored, and quick-setting adhesive, preferably a hot melt adhesive, is applied along the lines of folding. The sheet is then folded to the desired configuration and held until the adhesive has set thus establishing an accurate profile that withstands the action of the aqueous slurry of cementitious material and the application of the other sheet. The invention can be applied to various profiles, including square edge, tapered edge, rebated and tongue-and-groove.

Abstract: A smoke stop for doors is disclosed. The smoke stop comprises a metal frame with a slot therein extending substantially the entire length of the frame on the door side thereof; a movable lid pivotally attached along one outer edge of the metal frame and releasably attached to a second outer edge of the metal frame thereby completely enclosing the slot in the metal frame; and an intumescent material completely enclosed within the enclosed slot. When the door is closed and the frame and door are subjected to flames, the intumescent material expands causing the sealing of the space between the frame and the door and thereby providing a smoke stop between the door and the frame.

Abstract: A corner construction is provided which utilizes a support having an elongated metallic flange, a back-up clip resiliently engaging the flange, and a pair of panels. One panel has a surface thereof engaging a first portion of the clip and is secured to the flange. The second panel has a surface thereof engaging a second portion of the clip and is secured thereto. An edge of the second panel is in abutting engagement with the first portion of the clip. The clip is concealed by the first and second panels which are arranged in angular relation.

Abstract: A method is described for producing a dry pet food having a moisture content of less than 15 percent by weight. The dry pet food has a fibrous meat-like texture even though it contains a substantial amount of amylaceous ingredient. This texture is obtained by utilizing specific types of proteinaceous adhesives in conjunction with plasticizing agents and processing in a manner to form fibers.

Abstract: A safety lock bracket is provided for affixing the end of a door frame header having internal roller tracks to the end of a door jamb over which it is mounted.

Abstract: A smoke stop for doors is disclosed. The smoke stop consists of a metal frame with a slot therein extending along substantially the entire length of the frame on the door side thereof; a continuous tube within the slot, the continuous tube having retarded decomposability at the kindling temperature of the door and the continuous tube having one or more fins running the entire length thereof and projecting outward on the door side of the frame; and an intumescent material completely enclosed within the continuous tube. When the door is closed and the frame and door are subjected to flames, the intumescent material expands causing the sealing of the space between the frame and the door and thereby providing a smoke stop between the door and the frame.BACKGROUND OF THE INVENTION1. Field of the InventionThis invention relates to a smoke stop for doors.2.

Abstract: A paper product comprising mineral fibers and a nonfibrous, highly refined gel binder, the product having a thickness no greater than about 0.080 inches and an apparent specific gravity of between about 0.25 and about 0.85. The product may be a sheet no thicker than about 0.012 inches, or a paperboard.

Abstract: A highly nutritional baked product, high in both protein content and vitamin content, stable against loss of protein efficiency ratio and vitamin potency, and further stable against staling and microbial growth and process for preparing same is disclosed. The product is additionally shelf stable, requires no refrigeration, is low in calories, high in nutrition, low in cholesterol and low in reducing sugars. The product contains added vitamins and minerals and protein. Water content must be maintained between 15% and 45%, and the product is stabilized by having at least about 15% by weight of sugar or sugar equivalents with at least 3% by weight of a polyhydric alcohol in the base. The product may have a sugar containing topping and has a frosting containing vegetable oil or fat coated vitamins.

Abstract: A clip and assembly of two structural channels front-to-back by use of the clip, the clip having a one-channel connecting portion and means for gripping portions of the side flanges of the other channel.

Abstract: A hanger for mounting hollow metal joists perpendicular to headers and the like is disclosed. The hanger has a U-shaped top flange for hanging the hanger and a backplate suspended from the hanger with the backplate terminating at its bottom edge in a saddle for the joist to rest upon and with the backplate being bent outward and together at its upper portion to provide a support for the interior of the hollow metal joist.

Abstract: A multi-pocketed envelope is described. The envelope has side flaps which fold one underneath another with one projecting above the other to form two pockets, one above the other. The bottom then overlaps both side flaps sealing them to the base and forming a third pocket in line with the first two formed pockets. The top flap of the envelope folds over to cover the two pockets.

Abstract: A unitary integral metal stud formed of sheet metal for constructing a fire-retardant wall and the wall structure formed of a plurality of studs and a pair of spaced-apart layers of gypsum wallboard panels in abutting relationship, the stud comprising a web having a pair of flanges defining a wallboard panel-engaging channel on one side, and a kerf-engaging flange substantially centrally locatead on the other side, and means extending from the web and having a supporting surface adapted to have a second layer of gypsum wallboard panels affixed thereto. A first row of panels is engaged by the channel and kerf-engaging flange, whereas a second layer of gypsum wallboard panels is affixed to the supporting surface extending from the roof. Additionally apertures may be provided in the web to inhibit heat conduction through the metal stud, and additionally to provide space into which the edges of the wallboard panels may dissipate heat if they should become hot, as for example during a fire.

Abstract: A specially prepared fiber reinforcement and improved gypsum wallboard are disclosed. The fiber reinforcement includes a multiplicity of relatively long fibers which are disposed at the interface of the core and cover sheets of the wallboard and are adhesively bonded to the cover sheets and incorporated predominantly into the portion of the core immediately adjacent to the cover sheets.

Abstract: An apparatus for use as an extruder die is disclosed. The die comprises a cylindrical housing surrounded by heating means. Within the die is provided gas injection means which can be used to expand the hot extrudate.

Abstract: A metal stud for constructing a fire-rated wall and the wall structure formed of a plurality of studs mounted in runners and having at least two spaced-apart layers of wallboard panels with adjacent panels in abutting relationship, the stud being formed of an integral piece of sheet metal and comprising a single layer web having a first plurality of oppositely directed flange means at one edge thereof, a web substantially perpendicular to the flange means, and a panel at the other edge of the web for supporting wallboard panels.
