  • Patent number: 10096916
    Abstract: A connector has a fixing hole in an intermediate portion of a terminal member, and has an engagement portion projecting downward in a thickness direction, at an end portion at a front end side of the fixing hole. Therefore, when the terminal member is attached to a housing, movement of the terminal member toward a rear end side can be restricted by fitting a projection portion of the housing into the fixing hole. Furthermore, since the engagement portion is provided to the terminal member, movement of the terminal member toward the rear end side can be restricted by engaging the engagement portion with a front end surface of a protrusion portion of the housing.

At least one ledge is formed in a cavity wall of the mold proximate the position intended for receipt of an in mold label. The ledge protects the leading edge of the in mold label from the flow of resin through the cavity walls of the mold. Because the label leading edge is protected, the resin flows over the label and pins the label to the cavity wall of the mold, creating a container with the label formed on the container wall. Alternatively, a container lid is provided with a ledge to facilitate skirting and label placement on the pan area of the lid. These features both enhance the structural integrity and the uniform unblemished appearance of the finished molded container.

  • Patent number: 6655649
    Abstract: Isoelectric focusing gels are cast in a rod-shaped casting mold split longitudinally into two halves, each half having a half-circle profile so that the combined halves form a completed mold that is tubular in shape with a circular cross section. Flat grooves are cut into the flat contacting surfaces of each of the mold halves, the grooves in direct opposition to one another to form a chamber of rectangular cross section extending the full length of the mold and open at both ends. One groove receives a flexible backing strip for the gel and the other serves as the casting chamber for the gel. Once the gel is cast in this mold, isoelectric focusing can be performed as if the gel were a tube gel, and the two mold halves are then readily separated to permit removal of the gel and its transfer if desired to a second dimension separation.

  • Patent number: 6358444
    Abstract: To prevent a skid panel attached with wear resistance material of porcelain tiles or the like on its surface from warping in a longitudinal direction of laying the skid panel, a warp amount of a skid panel is predictively calculated from shrinkage strain, shrinkage force and upper and lower edge stresses of concrete, reverse camber is provided in the longitudinal direction of a mold of the skid panel with tensioning devices to nullify the final warp amount and concrete is fed to the mold to thereby fabricate the panel.

  • Patent number: 6322740
    Abstract: A method and apparatus for the forming of artificial leaves and flower petals, especially for use as a craft item, includes a male form for forming an armature for the leaf or petal and a female mold for generating the leaf or petal body. A flexible wire is wrapped about the male form to form an armature with an extending stem. The armature is removed from the form and placed in the mold. The mold is then filled with a film-forming casting material, such as a polyvinyl acetate. Upon cure, the artificial leaf or petal is removed from the mold. The leaf or petal may be combined with other leaves or petals similarly formed to form an artificial floral arrangement.

  • Patent number: 6164037
    Abstract: A formliner for use in manufacturing a decorative panel made up of a layer of concrete or other cementitious material interconnecting a layer of spaced apart bricks or other decorative elements, secured in the cementitious material. The formliner is made of a resilient elastomeric material and has a generally planar layer with a plurality of upstanding laterally and transversely extending ribs that extend from the generally planar layer to define a plurality of brick receiving recesses. Each brick is received in a respective recess with its front face positioned toward the generally planar layer. The ribs extend partly up the sides of the brick from the generally planar layer to allow cementitious material to partly fill the spaces between the sides of the bricks. Cementitious material is prevented from reaching the front faces of the bricks within the recesses by a plurality of ridges that extend from the ribs to sealingly engage an adjacent surface of the brick within the recess.

  • Patent number: 6032424
    Abstract: A construction block is disclosed along with a method of producing and assembling a plurality of the construction blocks where the blocks have internal cages around a central passage, said central passage opening to top, bottom or side openings in the blocks, and from which cage support rods extend to hook chain lifts to the blocks and to guide bottom openings of top blocks into predetermined alignment with the top opening of the bottom blocks. The casting technique allows not only for the novel lifting and alignment construction of the blocks, but also allows for novel external and internal features to be incorporated into the blocks, such as mounting bolts for interior walls and bricks or brick facades for the exterior walls of the blocks.

  • Patent number: 5922235
    Abstract: An individual bracket for holding and securing an object to the surface of a construction form for embedding the object in a settable material, such as concrete, and exposing the face surface of the object in the finished construction. The bracket has an outer configuration formed from a plurality of side and end perimeter members that defines a recess that correspond with the outer configuration of the object. The perimeter members have a flat outer surface extending at right angles to the form and an inwardly extending flange which is parallel and in contact with the form. An upwardly curved inner surface extends from the flange to the outer edge of the flat outer surface which forms one-half of a mold to form a grout line when two brackets are connected together. The actual mold can be any shape desired to provide the various types of grout lines.

  • Patent number: 5900180
    Abstract: A disposable object form line for use in horizontal casting of building panels from settable material in which at least one side has an exposed face of embedded objects. The object form liner is comprised of a thin support sheet having an adhesive coating on one side. A closed cell plastic grid having ridges which define openings sized to fit the outer perimeter of the intended objects is provided. The grid is adhered to the adhesive coating on the support sheet. Retarder strips may be inserted in each opening to prevent contamination of the face of the object during the pouring process. The form liner is placed in the bottom of a horizontal mold. The objects, such as bricks, are positioned in the openings provided in the layout form liner and the settable material is poured into the mold to form a construction panel. After setting, the panel and disposable form liner are removed from the mold and the liner is stripped from the panel to expose the objects embedded in the surface.
