  • Patent number: 7279065
    Abstract: The present invention relates to a method for forming a bi-layered carpet underlay. More particularly, the method includes bonding a layer of non-woven fibers and a layer of re-bonded foam particles together to form the bi-layered carpet underlay. The layers of the carpet underlay can be bonded together with the use of adhesives, by heating a surface of one or both layers to a soft bondable state for lamination between the layers, by applying a film having adhesive surfaces between the layers, or by other suitable bonding means. The bi-layered carpet underlay combines the soft cushioning resilience of foam with the high durability bridging ability of fiber to provide a carpet underlay that maintains its height or thickness and firmness, while imparting softness and cushioning effects over an extended period of wear.

  • Patent number: 6660123
    Abstract: A device embodying the invention comprises a pair of members presenting a lower base surface and a member presenting an upper parallel surface when in an operative position. A platen pad material, which converts microwave energy to heat, is provided on one of the surfaces. When in an operative position the two platens provide uniform pressure over the surfaces of a laminating pouch carrying a document. The device is placed in a domestic microwave oven and the oven is operated for a period of time dependent on the rated power of the oven, the size of the document and the energy conversion capability of the platen pad. The platen pad converts the microwave energy to heat energy while applying uniform pressure over the surfaces of the pouch. This produces liquefaction of the adhesive which bonds the film to the document. The device is then removed from the microwave oven, permitted to cool, the lamination removed, and trimmed as may be necessary.

  • Patent number: 6592021
    Abstract: A circuit assembly having a thin and large-area dielectric substrate and an improved grounding condition. To make the assembly, a circuit board comprises the substrate, and a circuit pattern and a metal layer that are formed on respective sides of the substrate. A bath of conductive bonding material (e.g., a low melting point solder) is made inside a tray-like metal chassis of the assembly. The circuit board is floated on the bath and excessive portion of the conductive material is absorbed. A branch circuit for branching a first path into at least two second paths is provided by mainly using impedance transformers but by using fewest possible stubs. Also, the elements are arranged in symmetry around the axis through the first path. This yields a wide operating frequency band. A waveguide-microstrip line transition that is easy to work and low in transition loss is provided by shaping the wider walls of the ridge waveguide so as to spread out toward the end.
