Abstract: In a demountable office partition system, batten mounts with a base and legs of a resilient hard plastic are snap fit to supporting structures by reason of inwardly directed opposed flanges on the legs. The legs of the batten mounts also have soft plastic externally directed fingers to which a batten may be press fit. Use of the batten mounts permits the batten to be removed without damage. In another embodiment, the base of the batten mounts have a first set of depending inner legs with inwardly directed flanges and a second pair of depending outer legs with outwardly directed flanges outwardly spaced from the inner legs. The batten mount is fabricated of a resilient hard plastic. Again, the batten mounts may be snap fit to a supporting structure. However, in this embodiment, a batten is snap fit to the batten mounts. The batten may be removed from the batten mount without damage due to the resilience of the outer legs.

Abstract: A free standing portable arch for use in weddings, different types of ceremonies and other occasions. The arch is adapted for a bride and groom to stand under while taking wedding vows, posing for wedding pictures and for walking through during the ceremony. An upper portion of the arch includes a first half and a second half. The second half is a mirror image of the first half. The first and second half, when joined together, form a geometric shape such as a heart shape, a star shape, a diamond shape and the like. A lower portion of the arch is formed into an inverted "T" shaped stand. A bottom horizontal member of the stand is used to support the arch on a ground surface or a floor surface. The arch may be constructed of a variety of materials with a preference being lightweight plastic cylindrical tubing. The upper portion and the lower portion of the arch can be decorated with ribbon, floral material and strings of lights for adding color, illumination and attraction to the arch.

The wall comprises a plurality of blocks arranged in layers one above the other, each of the blocks having first and second sides, an exterior face, an interior face, a top and a bottom, and at least one cutout extending through the block between the top and bottom. The tops of adjacent blocks in each layer are adapted to be located in a common plane and each block is adapted to be separated from an adjacent block in the layer by a predetermined distance.

Abstract: A siding positioner/fastener that consists of a strip 40 with a continuous length, with inserts 50 coupled to it, at spaced intervals along the length of the strip. The strips are positioned and coupled to a substrate, aligning the strips perpendicular to the channel 70 length, which is parallel to the siding length, with a strip at each interval along the siding length, and with the inserts inline and parallel across each strip interval. A sloped channel is coupled to the back of the siding length. At each end the channel can slide on, or be pressed onto the inserts. The remaining inserts are pressed on. Each time an insert is locked onto the channel this aligns the following insert. When all the inserts are locked onto the channel, the siding can be moved parallel to the its length, or expand and contract its width. The insert length will allow two pieces of siding to be butted against each other on one insert.

Abstract: A post tensioning anchor plate assembly comprising an anchor plate and coupling elements therefor. The anchor plate is constructed with a pair of oppositely disposed, concentrically aligned cylindrical bosses, or mounting members, projecting from opposite sides of a generally rectangular plate. The oppositely disposed bosses define, on the inside surface thereof, a common tapered bore adapted for receiving a post tensioning cable therethrough and securement thereof for post tensioning of a concrete section. The outside surface of each boss is likewise constructed with a circumferential groove adapted for receiving an inwardly projecting lip of an appropriate plastic cap or tubular adapter secured thereover. In this manner, the plastic cap and tubular adapter can be mounted to opposite sides of the anchor plate in sealed engagement therewith for facilitating improved reliability of the post tensioning anchor plate assembly.

Abstract: The force transfer body comprises a first, essentially annular partial body, preferably of cast steel, and a second partial body, preferably of a castable mortar mass capable of hardening. The second partial body is cast in one piece with the first partial body. An inner conical aperture is lined with a funnel-shaped plastic part, which overlaps at least a section of the first partial body. The first partial body has an abutting surface, turned away from the part of the structure, serving the firm contact with an anchor head containing individual members. The prestressing forces arising concentratedly with the anchorage are conveyed from the anchor head via the first partial body into the second partial body, and from there into the part of the structure. The second partial body is designed essentially frustoconical, the truncated cone extending, tapering, away from the first partial body. In the area of the outer generated surface of the second partial body there is a circumferential constriction.

Abstract: A concrete repairing agent injection plug for injecting the concrete repairing agent into an injection groove formed in a concrete wall to be repaired, The injection plug and the injection groove provide sufficient fluid tightness regardless of surface irregularities of the wall adjacent or around the injection groove so as to avoid leakage of the repairing agent during injection work. A elastic member is provided which is partly or fully inserted into the injection groove. First and second pressure plates are provided for interposing therebetween the elastic member. Distance between the first and second pressure plates is changeable by a pressure mechanism. When the distance is reduced, the elastic member is compressed and is laterally expanded to brought into intimate contact with walls of the injection groove to thus close an open end portion of the groove.
