Abstract: Two-sided and two-sided mirrored fire barriers having each of their two sides tested, rated, and certified for use in common spaces, such as spaces shared between two rooms are taught. Two-sided barriers require only one barrier and one installation, instead of the two presently needed. Two-sided barriers may have different construction and composition on each side; whereas each side of a mirrored fire barrier is a mirror image of the other. All two-sided barriers include top-mounted, bottom-mounted, and side-mounted barriers, gas and moisture impermeable barriers, and barriers shaped to fit into the expansion joint spaces created when a plurality of expansion joints intersect. The barriers are disposed to various sizes, lengths, widths, and depths, in addition to variations in shape, content, number and composition of layers, materials, and attachment means required to accommodate the variety of sizes and shapes of expansion-joint spaces and the desired rating, in terms of hours.

Abstract: A fire barrier assembly includes a fire barrier, mounting elements and securement elements. The mounting elements are positioned along the length of the fire barrier on an inner surface of the fire barrier. The mounting elements engage one or more of the securement elements to the fire barrier. When installed within an expansions space, the securement elements are used to tension mount the fire barrier assembly securely and generally immovably within the expansion space, without the need for any mechanical, adhesive, or other fixed connection to anchor the fire barrier assembly in place. As such, no modification to the building structures defining the expansion space (e.g. no drilling holes, applying adhesive, etc.) is need to mount the fire barrier assembly. If desired, the fire barrier assembly may easily be detached and removed from the expansion space.

The first clip is coupled to the first panel by a fastener. The lower leg portion of the first clip and the first panel define a first downwardly opening slot. The second clip is coupled to the first panel by a fastener with the upper leg portion of the second clip located above the upper end of the first panel. The third clip is coupled to the second panel by a fastener. The lower leg portion of the third clip is configured to be inserted into the upwardly opening slot defined by the upper leg portion of the second clip and the wall of the elevator cab to support the second panel relative to the first panel.

Abstract: An elastic seal for a building joint which includes internal walls or dividers which change orientation when the seal is compressed for placement into the building joint. The change in orientation allow for the seal to apply a relatively uniform force against the joint walls extending from the bottom wall to the top wall of the seal. Additionally, the change in orientation reduces the deflection of the top wall of the seal upwardly when compressed in the building joint. The walls also become more vertically oriented when the seal in compressed. This vertical orientation provides increased load support for the top wall when the seal is compressed into a joint.

Abstract: The invention relates to a composition for use in the production of an article of manufacture, and in particular, to the manufacture of wall and corner guards. The composition includes a biopolymer in combination with PETG as well as a modifier. The biopolymer and modifier are preferably produced from an annually renewable source such as corn or sugar as opposed to traditionally used petroleum based plastics. In this manner, the composition of the invention is relatively environmentally friendly as compared to known compositions while maintaining many of the desirable qualities thereof. In addition, the production of the articles of manufacture results in the consumption of fewer fossil fuels and less production of pollutants.

Abstract: This disclosure is concerned with a readily changeable sign display system which facilitates easy alteration of the sign indicia displayed but is also resistant to unauthorized tampering so that it can be deployed where it is not under continuous surveillance when exposed to the general public. It comprises vertical frame members which provide tracks for the insertion of horizontal frame members. In some embodiments the vertical frame members are joined to each other with a backing member while in other embodiments intermediate channel members are placed between the vertical frame members and adjacent members are joined by a backing member. The horizontal frame members carry grooves for the insertion of sign panels which carry indicia. The tracks for the horizontal frame members carry removable obstructions which hold these members in the tracks. The obstructions at the upper end of the tracks are readily removable.

Abstract: The present disclosure is concerned with an improved latching mechanism for the hinged section of a ceiling track for traveling curtain. The latching mechanism is designed to make a readily audible sound when it is locked. It is based upon a generally oval shaped lock knob which passes through a generally oval shaped aperture in the bottom wall of a receiver for the lock knob. The aperture is designed so that when the lock knob is rotated its long axis no longer aligns with the long axis of the aperture it can no longer pass through the aperture. The bottom wall of the receiver carries two upwardly extending side walls that must be pushed outward to allow the passage of the lock knob as it rotates and that carry gaps that accommodate the tips of the lock knob and allow the side walls to move back toward their undeformed position.
