  • Patent number: 11156032
    Abstract: A window screen that allows for the easy fix of a torn screen. The screen is similar to contemporary window screens. However, this screen contains a grid of squares that can be between 4×4 inches and 8×8 inches in size. The border of each square is a solid fiberglass material which can be 0.5 to 1.0 inch in width. Inside of each square is standard window screen mesh. In the event of a tear, the mesh within the borders of the squares can be cut out. Then, a replacement patch which is the same shape of the removed area can be adhered in place. The patch should be cut so that it contains the surrounding fiberglass border. The border of the patch will be adhered to the window screen so that the borders of the patch overlap the borders on the screen making for a seamless repair.

    Abstract: A three-dimensional cellular light structure formed of continuous wire groups. For example, six orientational helical wire groups are intercrossed in a three-dimensional space and form a uniform pattern. In a manufacturing method, a frame assembly of rectangular frames and connection support bars is used. The method includes arranging and fixing first axis wires on the frames, connecting the frames by connection support bars, and assembling second axis wires to make a three-dimensional cellular light structure. The intersection points of the wires may be bonded. It can be a fiber-reinforced composite material by filling at least part of an internal empty space of the structure.

    Abstract: Disclosed is a structural material having a wire lattice configuration. The structural material can manufactured by first weaving a continuous wire filament on a loom assembly. Once woven into arrays of parallel wires, the filament is fixed in position and cut into segments. The segments are then placed in a rig. The rig positions the segments at relative angles so as to form a matrix or mesh. In the final step of the manufacturing process, the wires are welded together using, for example, a forge press. Alternatively, the material can be formed by first holding wire segments in a pair of rigs and then sequentially welding the wire segments together. The structural material of the invention can be used alone or layered to form a multilaminate material.

  • Patent number: 4466467
    Abstract: A stirrup reinforcement mat in which the stirrup projections have a question mark configuration so that the extremity of the laterally extending top portion of each projection does not extend to any significant degree beyond the vertical plane defined by the base wire to which the stirrup projection is joined. This configuration is believed to enhance the strength of a concrete product reinforced with this mat and also minimizes tangling when the mats are stacked together for storage or shipping.

  • Patent number: 4441527
    Abstract: A cage assembly for spacing inner and outer concrete pipe reinforcing welded wire cages from one another through the use of a spacer bar. The spacer bar includes a plurality of links, each having a hook-shaped deviation therein, joined by a tie rod. The links are inserted through one of two cages until the tie rod abuts the cage and the hook deviations are then hooked over a longitudinal or circumferential wire or both in the other cage. Each link also includes at least one form spacer projection projecting from one end thereof in order to space the entire inner and outer cage assembly from the inner and/or outer wall of a pipe form.

  • Patent number: 4369941
    Abstract: A reinforcing strip of wire mesh for coatings on pipes, comprising a plurality of parallel longitudinally running warp wires provided with incurvations for giving the strip a longitudinal extensibility which increases gradually along the breadth of the strip. The adjacent warp wires are connected by obliquely running weft wires which are welded to the warp wires in the crossing points, preferably by one single continuous weft wire running in zigzag along the length of the strip.

  • Patent number: 4358078
    Abstract: The specification discloses fabric for use in reinforcing concrete pipe. The fabric includes a plurality of circumferential defining line strands and a plurality of transverse strands positioned in spaced, parallel relationship to each other and extending generally perpendicular to the circumferential defining line strands. The transverse strands are divided into a plurality of sets having lengths equal to the predetermined reinforcement cage circumference. The circumferential defining line strands are divided along their lengths into quadrant defining portions. Additional reinforcement is provided at the quadrants wherein the areas of maximum stress will occur in the concrete pipe.

  • Patent number: 4297418
    Abstract: A special component strand for wire fabrics, the fabric consisting of one or more of the special strands extending in spaced apart generally parallel relation, and spaced apart, generally parallel cross wires extending transversely to the special strands, each cross wire being attached to each of the special strands at its point of intersection therewith, as by piercing said special strand or by being wrapped or twisted tightly thereabout. The special strand of the present invention consists of a spring wire core having a sheath of tough but compressible material having alternating ribs and grooves formed longitudinally in the surface thereof, the ribs permitting easy indentation of the strand by a cross wire twisted thereabout, for a more secure connection, and a pair of opposite grooves thereof reducing the strand to a relatively narrow neck for easier piercing by said cross wires.
