Patent number: 4445956Abstract: An improved method and material for securing a thin-edged deformable structure, such as a honeycomb core, so that the structure may be machined while it is in a generally stabilized condition. The material is a laminate which is bonded to one side of the structure to be machined. The laminate is then secured by vacuum and the structure is then machined in a desired manner. The laminate includes a first stabilizing layer formed from a mesh of fiberglass, nylon or the like and having relative large openings. The mesh is impregnated with a suitable epoxy or phenolic resin which acts as an adhesive to secure the mesh to the structure. A fabric of nylon or the like is applied over the mesh and bonded thereto. A third and final layer includes a non-porous plastic sheet which permits the laminate to adhere by suction to a vacuum chuck. After machining, the fabric and non-porous layers are removed, leaving the open mesh layer fixed to the structure to stabilize it.Type: GrantFiled: February 14, 1983Date of Patent: May 1, 1984Assignee: Hexcel CorporationInventors: Bob L.

Patent number: 4374691Abstract: A composite material and method for forming graphics such as letters or numbers that are pressure transferable to a substrate. The composite material includes an accepting tape including a layer of latent adhesive material on a receiving web, and a friable slightly adhesive layer lightly adhered to a donor web. When the layers are pressed together and the composite material is selectively heated in graphic patterns, corresponding portions of the adhesive material and friable layer adhere together so that upon subsequent separation of the layer of adhesive and the donor web portions of the friable layer transfer to the accepting tape in the heated areas to provide graphics. When the graphics are then positioned against a substrate and are pressed against the substrate by rubbing pressure applied through the receiving web, the adhesive layer will tear around the graphic and separate from the receiving web over the graphic so that the graphic will be transferred to the substrate.Type: GrantFiled: May 9, 1980Date of Patent: February 22, 1983Assignee: Minnesota Mining and Manufacturing CompanyInventor: Jan D.

Patent number: 4109041Abstract: Elastomeric particles, e.g., rubber grindings and buffings produced in vehicular tire manufacturing and recapping operations, are incorporated into at least one surface of particle-board panel to increase friction, prevent stacked panels from sliding in echelon, prevent tools from sliding thereon, prevent workmen from slipping thereon, and still allow the panel to be cut and nailed. The particles can be bonded to the panels simultaneously with the panel molding operation or in a separate subsequent operation. In a preferred method of fabricating a non-skid construction panel of the subject invention, rubber particles in the range from below about 10 to above about 20 pounds per one thousand square feet of surface area are distributed over a panel, and the rubber particles and the panels are subsequently subjected to heat and pressure, and the resulting panel has a smooth surface with the elastomeric particles being used somewhat as a light "salting" of the construction panel's surface layer.Type: GrantFiled: November 4, 1977Date of Patent: August 22, 1978Assignee: Champion International CorporationInventor: Stephen J.
