  • Patent number: 8464481
    Abstract: A corner block has spaced-apart front and rear sections interconnected by two spaced-apart side sections that jointly define a through-cavity that extends through the block from a top face thereof to a bottom face. Upper protrusions are provided on the top face of the block, and lower protrusions are provided inside the cavity at the bottom of the block. The upper and lower protrusions are configured and arranged relative to one another so that when two corner blocks are stacked one atop another with one block rotated 90 degrees relative to the other, the upper protrusions of the lower block interlock with the lower protrusions of the upper block to interlock the two blocks. The corner blocks are constructed in two variants, a corner block A and a corner block B, which are mirror images or opposite hands of each other. The corner blocks A and B are alternately stacked upon one another to construct a 90-degree corner of a segmental retaining wall or other wall structure.

    Abstract: A building block or panel having the shape of a right parallelepiped having two opposed major faces (11), the remaining faces being edge faces which are formed to interlockingly engage with the edge faces of similar building blocks wherein two pairs of adjacent edge faces at opposed sides of the block are each formed with an elogate recess (13) extending from the respective corner of said adjacent edge faces to an intermediate location on each edge face, each edge face being formed with an elongate projection (15) which is able to be received in the recess (13) of a corresponding block; the one end (17) of each projection (15) adjacent the respective recess (13) being contoured to define at least a portion inclined at an angle of less than 90.degree. between the face and the base of the respective recess wherein the other end of each projection (15) has a face of a complementary configuration.

  • Patent number: 4557093
    Abstract: An insulating building block made up of an insulating core and two concrete walls, each cast over one side of the core. The latter comprises a body having opposed parallel flat outer faces, bound by parallel longitudinal edges and parallel side edges, and having a transverse plane normal to the outer faces centrally between the longitudinal edges. Locking protrusions are formed integrally with the body and project from the outer faces. Each protrusion extends from either side of the transverse plane toward the longitudinal edges and terminates short of the longitudinal edges. The protrusions have outer surfaces and lateral edges tapering inwardly between the outer surfaces and the body outer faces. The protrusion side edges further make angles with the transverse plane suitable to facilitate demolding of the core when the core is molded in two half molds having a closure plane co-planar with the transverse plane, aforesaid.

  • Patent number: 4443509
    Abstract: A method of forming an insulation module for insulating the walls of a furnace, the method including forming holes at spaced intervals in a cold face of a mat of ceramic insulation material, applying a liquid adhesive to the cold face, vibrating the adhesive to cause the adhesive to penetrate into the holes of the mat, and providing a backing panel on the cold face.

  • Patent number: 4170856
    Abstract: A refractory brick unit is disclosed which is resistant to heat induced expansion spalling by virtue of the provision of a metallic sleeve member around four sides of the brick body with the metallic envelope being constructed in a manner such that two adjacent side sections thereof are spaced from proximal side walls of the brick and supported in such disposition by elongated tabs integral with the sleeve member side sections and slidably received in complemental elongated depressions therefor in the opposed sidewall of the brick body. When the brick units are laid in side-by-side relationship with one side of a corresponding metallic side section abutting the side section of a proximal brick unit, the sleeve members as well as the brick units are able to undergo heat induced expansion without placing compression loads on the bricks which could cause spalling of the brick bodies.

  • Patent number: 4086737
    Abstract: A refractory fiber blanket furnace lining module with compensation for heat shrinkage, and method of assembly of such a module, are disclosed. In the module as assembled, the refractory fiber material is in compression in horizontal planes coplanar with the hot face and also in compression in planes vertical to the hot face. Upon or after installation, the horizontal compression is removed so that the fibers may expand to compensate for heat shrinkage as such shrinkage occurs and maintain a seal in joints between adjacent modules.

  • Patent number: 3950908
    Abstract: A safety panel assembly for covering the walls or floors of areas such as playgrounds and the like is formed with a rigid planar carrier element having a spaced resilient covering element mounted thereto. The carrier element has recesses into which mounting projections integrally formed on the covering element extend. A hardened binder material locks the mounting projections in place and a plurality of spacer elements or ribs abut the rigid carrier element to provide hollow spacing between the elements and to insure a cover panel assembly exhibiting sufficient resiliency upon impact.
