  • Patent number: 7287356
    Abstract: A welded wire lathing material for mounting stucco plaster and the like onto a building frame. This lathing material comprises intersecting transverse and primary longitudinal strands substantially located in a first plane. It also comprises secondary longitudinal strands also substantially placed in first plane and closely spaced with, some of primary longitudinal strands, thus forming longitudinal slots located at predetermined spaced intervals extending across the lathing material. The slots are wider than the shaft, but narrower than the head, of fasteners predetermined for attaching the lath to building frames. The longitudinal and transverse strands are welded together where they intersect to form a rectangular mesh approximately located in the first plane.

  • Patent number: 6820387
    Abstract: A self-furring wire lath has stiffening trusses. In a preferred embodiment the lath comprises a grid of intersecting transverse and longitudinal wires welded at their intersections. Stiffening trusses are formed at bent sections in the transverse wires by first longitudinal wires affixed at the shoulders of the bent sections and second longitudinal wires affixed on the bent sections. A barrier layer is disposed between the first and second longitudinal wires. A building paper backing may be affixed to the barrier layer. The lath reduces cracking and wastage of stucco while remaining easy to work with.

  • Patent number: 6668501
    Abstract: A shear wall system comprises stucco fasteners consisting of an elongated first portion that is driven into a wood frame wall, and an elongated second portion that is completely embedded in a stucco wall panel. In one embodiment, the fasteners consist of an assembly having a first element that is driven into the wood frame wall, and a second annular element receiving a portion of the first element and that is embedded rigidly into the cement stucco wall. Ductile movement of the fastener components with respect to wood frame wall and the stucco wall provides energy dissipation.

  • Patent number: 6305432
    Abstract: The invention relates to metal wire mesh having a plurality of longitudinal wires and a plurality of transverse wires. The longitudinal wires of the mesh are provided with shaped areas wherein the moment of inertia of said shaped areas about the neutral axis parallel to the plane of the mesh is 90 percent or less of the moment of inertia of said shaped areas about the neutral axis vertical to the plane of the mesh. This substantially reduces the problem of curvature set when metal wire mesh is rolled for packaging or transport and attempts are made to unroll prior to use.

  • Patent number: 5017795
    Abstract: Apparatus is disclosed for detecting irregularities or flaws in seams such as the seams of cans. The apparatus includes means for irradiating the surface of the seam to produce reflected radiation signals, a plurality of radiation sensors, each having a selected field of view of the surface, and each producing sensor output signals dependent on reflected radiation signals received within such field of view. A signal processing means receives sensor output signals for a succession of fields of view along the longitudinal length of the seam and derives therefrom signal data representing a dimensional feature of the seam. Signl comparison means compares such derived data with signal data representing an acceptable dimensional limit and produces a rejection signal in the event that the dimensional feature does not fall within the limit. Means for classifying the nature of an irregularity is also disclosed, as is transport means for the movement of seams though the field of view of the sensors.

  • Patent number: 4038191
    Abstract: A header unit designed for use in a blood dialysis device, providing laminar flow conditions with no regions or stagnation or turbulence which could cause blood hemolysis. The specification discloses a diffuser adapted to provide uniform and nontraumatic diversion and diffusion of blood from a blood supply tube having a given cross-section area to a treatment face of a dialysis device in which said treatment face is of larger surface area than said supply tube. The diffuser comprises a first diffuser section of pipe continuous with the supply tube, flow turning vanes, and a second diffuser section leading to the liquid treatment face.
