Abstract: A top enclosure for drinking vessels is disclosed. The enclosure enables young children to drink from the drinking vessel only when handles on opposing sides of the vessel are depressed. If only one handle is depressed, such as if the vessel drops on the floor and rolls over on one handle, then the top enclosure remains closed and fluids cannot run out of the vessel.

Abstract: An apparatus for monitoring the output of a fiber cutter arranged to cut long fiber roving strands into short clippings and to feed the clippings into a slurry-containing mixer, the monitoring apparatus having a plurality of rotatably mounted assemblies each comprising a rotating shaft and a plurality of arms mounted thereon. During normal operation the fiber clippings fall through the moving arms and into an apparatus wherein the fibers are mixed into a slurry, such as a calcined gypsum slurry. Malfunction of the cutting apparatus resulting in the discharge of long fiber strands causes entanglement of the fiber strands with the moving arms, thereby causing rotation of the assemblies to discontinue and actuating an alarm and automatic switches, thereby rendering the entire apparatus inoperative and preventing serious entanglement of the mixing and conveying apparatus which could result in long shut-down periods.

Abstract: A method for making an article such as a chair seat or the like is disclosed with the method including: attaching a rigid insert to one-half of a mold with an air permeable material extending from between the rigid insert and the mold outward toward the edges of the first half of the mold; inserting a liquid foamable reaction mixture into the cavity of a second half of the mold, placing the two mold halves together with the air permeable material extending from the cavity of the mold to the exterior thereof; allowing the reaction mixture to cure and form a rigid hard structure throughout while expanding around the sides of the rigid insert; and removing the finished article from the mold.

Abstract: A quickly assembled door frame formed of sheet metal and having a generally U-shaped cross-section, one of the frame members being adapted to mount a hinge having a portion embossed to provide a recess to receive a plate of the hinge, a plurality of slots provided in a side wall, and a hinge anchor plate having engagement tabs adapted to be inserted into the slots and having threaded apertures adapted to engage screws engaging the hinge plate and passing through apertures provided in the frame member. In an improved embodiment secondary embossments are provided in the frame member defining alignment channels, and the hinge anchor plate is provided with guide tabs adapted to be received within channels, thereby maintaining the engagement tabs of the hinge anchor plate in engagement with the inner wall of the primary embossment.

Abstract: A support runner for use in a suspended ceiling system is disclosed with the support runner being useful in ceiling systems having an exposed flange for decorative purposes. The support runner has a decorative trim having a decorative lower surface and an engageable upper surface. An inverted-T runner is supportingly engaged about the engageable upper surface of the decorative trim and extends along the decorative trim a distance sufficiently less than the length of the trim to accomodate heat expansion distortion of the inverted-T runner. When the ceiling system is exposed to heat, the inverted-T runner continues to hold the ceiling panels even though the decorative trim becomes inoperable due to expansion caused by the heat.

Abstract: A hanger is disclosed for supporting sound absorption panels wherein the panels have a top frame member with a depending lip portion. The hanger has a horizontal portion and a vertically downwardly depending portion, with the vertically downwardly depending portion having an upwardly and inwardly formed portion which can engage the depending lip of the frame of the panel to support the panel while the horizontal portion of the hanger is attached to supporting means. The formed portions can be useful in holding together abutting panels.A horizontally movable sound absorption wall is disclosed having one or more sound absorption panels supported by a top frame member, a hanger attached to the top frame member, and a track and guiding means for guiding the hanger along the track.

Abstract: A paper covered gypsum board and a process for its manufacture, with at least one cover of the board comprising a multiply paper sheet containing a major proportion of cellulosic fibers and a minor proportion of short mineral fibers.

Abstract: A marshmallow product is disclosed for use in producing stabilized, high protein food bars. The product includes a marshmallow having a density of from 30 to 74 oz. per gallon in intimate admixture with a mixture of polyhydric alcohol, non-reducing sugar and high protein ingredients of reduced water binding capability with the high protein ingredients including heat treated protein and fat coated protein. The marshmallow product has a water activity, A.sub.w, less than 0.85. The marshmallow product may also include fat coated vitamins.

Abstract: A marshmallow for use in food bars and the like is disclosed containing from 1-20 percent by weight fat coated casein and caseinate salts and being low in reducing sugars.

Abstract: A clip is disclosed for use in joining juxtaposed sound absorbing panels having a sound absorbing material held in a frame extending around the outer edge of the sound absorbing material, said frame having a projecting lip portion. The clip comprises a front plate having opposing end sections; offset members extending backwardly from the opposing end sections; and, opposing securing members extending downwardly from the back of the offset members. Adjacent sound absorbing panels are placed together by the securing members of the clip being placed between sound absorbing material and the frame of two adjacent panels. The sound absorbing panels may be either individual, smaller panels or may be a larger panel made up of smaller panels, stacked one on top of the other, and having a vertical frame member common to the vertical edges with the frame member having a U-shaped cross-section. Also disclosed is the sound absorbing panel system made possible by use of the clip and panels.

Abstract: This invention relates to boardlike, load bearing, construction units formed from a tensile portion substantially uniformly distributed over the entire area thereof and which also has fastener holding properties and a cementitious material of good compressional strength forming substantially the remaining portion of the unit with novel means for effecting a bond between the tensile and compressional portions along with means for manufacturing the units and their use in various systems of construction.

Abstract: An acoustical tile comprising a relatively thin, flat body of acoustical composition including fibrous material and a binder, and a paper backing affixed thereto having a fire-retardant material dispersed therein, the outer facing surface of the tile being either planar or slightly convex.

Abstract: A structure comprising a door panel having an elongated opening therein, and resilient mounting means on the panel engageable with a rail for moving the panel along the rail, the mounting means comprising a glide including a body disposed on one side of the panel, a roller rotatably mounted on the body engageable with the rail for movement of the glide thereon, a shank on the body extending through the panel opening and moveable therein for relative movement of the glide and the panel, detent grooves provided at both sides of the shank, and flanges provided at both sides of the elongated opening integral with the door panel, the edges of the flanges being disposed within the detent grooves of the shank, thereby retaining the glide slidable within the elongated opening.
