Abstract: An injection plug device for injecting an epoxy resin repairing agent into an arcuate injection groove formed in a concrete structure. A rod member made of the same or similar epoxy resin as the repairing agent, is inserted and attached in the groove and has an injection hole at its center through which the repairing agent is injected. A tube member protrudes from the center of the rod member and has an inner end portion communicating with the injection hole of the rod member. A pipe member is inserted into the tube member, and a check valve mechanism is provided between the inner end portions of the pipe member and the tube member. After the resin is injected into the concrete structure and the resin is solidified, the pipe member is easily broken and removed from the rod member, together with the pipe member and the check valve mechanism.

Abstract: A utility pole constructed from composite material. The pole has a triangular shaped first composite member which has an inner channel defined by three walls that intersect at three corresponding apexes. Within the first composite member is a second triangular shaped composite member that has three walls that intersect at three corresponding apexes. The apexes of the second member intersect with the walls of the first member so that the second member walls extend across the inner channel. The extension of the second member walls across the inner channel provides structural support for the walls of the first member and creates a relatively rigid composite utility pole. The utility pole may have additional triangular shaped composite members that are nested within the second member to further increase the stiffness of the pole.

Abstract: The present invention provides a method of making a frame, particularly for the aircraft industry, having a central member (34) and one or more cantilever ribs (32); such a frame can be made by forging or machining but these are time-consuming and expensive. According to the present invention such frames are made by diffusion bonding and superplastic forming techniques, whereby a pack of sheets are bonded together except in certain areas. Gas is injected into those areas to inflate the pack superplastically to form one or more closed cells (16). The top of the cells is then machined off along line 23, while the side walls of the cells are retained, to provide a frame having cantilever ribs (32).

Abstract: A beam member for use in construction, particularly as a waler in concrete form assemblies, and a method of producing the same. The beam member is flexible to a preselected curvilinear shape and adapted to be held in said preselected curvilinear shape, and includes a flexible face and a plurality of flange members secured to and upstanding from the flexible face, the flange members being arranged side-to-side in two rows, one each of which rows is adjacent a corresponding one of opposing sides of the flexible face. Each of the flanges has a terminal end section extended parallel to the flexible face and is separated from an adjacent flange by a distance which increases from the attachment of the flange at the flexible face to said terminal end section whereby the beam member is laterally flexibly movable to conform to a preselected curvilinear shape. A strap is secured to the terminal end section of the flanges to maintain the preselected curvilinear shape of the beam member.

Abstract: A concrete dowel slab joint system is provided for maintaining adjacent sections of concrete in alignment during contraction and expansion of the concrete, and for transferring shear stresses and bending moments across a joint formed between adjacent concrete slabs. It includes a sleeve assembly for receiving and maintaining the dowel bar therewithin. In this is way, the dowel bar does not transmit substantial shear stresses to the concrete during the contraction and expansion of the concrete. The sleeve assembly comprises an elongate sleeve body having an outer surface and an inner surface, and defines a hollow interior compartment, (b) at least one closed end, and (c) a sleeve member. Preferably, at least one collapsible spacer member is located within the hollow interior compartment. The spacer member is collapsible by interactive forces exerted by the dowel bar moving in a lateral and/or longitudinal path within the hollow interior compartment in response to the expansion and contraction of the concrete.

Abstract: A roof panel for sloped roofs includes a self-supporting reinforced plate concrete-like materials, wherein the reinforcement above the plate has bars running along the slope of the roof. In the vicinity of these bars, attaching elements are arranged which bear the roofing material. In order to protect these reinforcement elements from the influence of the weather, they are embedded into concrete ribs, whereby these concrete ribs undertake the function of holding the attaching elements for the roof covering.

Abstract: A drywall corner bead which includes a plurality of integral preformed barbs provided at intervals along the length of the corner bead for securing the corner bead to a drywall corner. The corner bead includes first and second longitudinally-extending flanges which are interconnected by a longitudinally-extending rounded nose, and the first and second flange are disposed at an angle of less than 90.degree. with respect to each other. The barbs project inwardly from the flanges in a generally perpendicular direction and have a length of less than about 3/32 of an inch. When the corner bead is applied to a drywall corner, the barbs penetrate substantially only the paper layer of the underlying drywall and secure the corner bead to the corner. The drywall corner bead can be rapidly applied to a corner without requiring additional tools or materials, and the corner bead is securely affixed to the corner by the barbs until the corner is finished with joint compound and paint.

A panel holding framework assembly is supported from the retainer loop and includes a panel holding framework supporting the ceiling panels.

Abstract: A backstop of the "venetian blind" type and contains a set of angled louvers to deflect projectiles safely. The present invention provides a system of modules whereby a backstop may be constructed across a wall of any width. The backstop modules themselves are made in a number of standardized widths, most preferably about 36 inches (0.91 m), 48 inches (1.22 m), and 60 inches (1.52 m) wide. Using various sets of these modules, any width can be filled in to the nearest foot, i.e., a maximum gap of about six inches remains between the end modules and an adjacent wall surface. These remaining gaps are preferably filled in using a sliding, angled wall plate that accommodates gaps between about zero and six inches. The visible flat edges of plates that form the sides of adjacent modules and the plate against the floor are ricochet hazards, and thus are also preferably provided with angled deflectors.

A rotating rod is operatively connected to the drive structure, ends of the telescoping frame are pivotally connected to opposing edges on the rotating rod. The drive structure provides power to turn the rotating rod to extend the telescoping frame to open and closed positions thereby opening and closing the canopy and allowing a vehicle positioned on the base to be covered by the canopy.

Abstract: A system for connecting wall panels in abutting edgewise relation, wherein abutting edges of the panels are formed with semi-circular recesses in them, includes pairs of spaced slots formed in the corners defining transverse semi-circular edges of the panel frames. Two connectors are provided having conical recesses for engaging the edges of the slots. The connectors are each fastened by a screw to an end of an elongate bar which fits within the recesses of the corners. When the connectors are fastened tightly to the bar, the engagement of the conical recesses with the corner edges draws the panels tightly together. By this system, the panels may be connected either in-line or at an angle of between 90 and 180 degrees, without the need for any special corner hardware.

Abstract: A presentation system is built up from individual presentation devices, which are in each case formed by a plate element, which is fixed to at least one and preferably two parallel section rails. The section rails are L-shaped and engage with their forwardly directed horizontal legs through a correspondingly shaped horizontal slit in the plate element. In this position they are screwed to the plate element. The profile section leg projecting forwards through the slit is used for fitting holders, fastenings, etc. The plate elements are interconnected at the ends of the section rails, e.g. by threaded bolts passing through bushes. A universal arrangement is possible.
