  • Patent number: 4683161
    Abstract: A monolithic ceramic body with ordered pores and a method of making a monolithic ceramic body is provided including applying a fugitive material in a pattern having a predetermined order, size, shape, orientation and location to a broad surface of at least one layer of green ceramic material. A second ceramic layer is juxtaposed in a stack with the first layer, with the fugitive material between the layers. The juxtaposed layers are laminated and the stack is heated to a first temperature to dislodge the fugitive material and provide a plurality of pores having a predetermined order, size, shape, orientation and location which matches that of the fugitive material pattern. The stack is then heated to a second temperature to form a monolithic ceramic body which includes the pores.

There are two arrangements and both provide economy of apparatus, space, labor and materials. Two thermoplastic film strips are carried from roll storage means to this air-cushioning forming means whereat the webs of film are locally heat-sealed together. A first film is fed to a heated roll whereat this film is heated sufficiently to be thermoformed on a cooled roll with cavities formed therein. These cavities are manifold-connected to a source of vacuum which draws the heated film into the formed cavities. The second strip of film is fed to another heated roll having a resilient covering material with thermoconductive metal powder as a substantial component, thus providing sufficient thermoconductivity and resilience to heat-seal or weld this second film to those areas around the cavities formed in the first film.

  • Patent number: 4472472
    Abstract: A protective device, such as a boxing helmet, rib or muscle protector, athletic mat, hockey helmet, motorcycle helmet and similar devices, is formed such that the major shock absorption is accomplished by a series of bowed, preferably plastic, members which flex when the device is subjected to an impact, so as to absorb the shock and dissipate its transmission to the user. Because of the nature of these bowed members, when the shock has been dissipated, the member returns to its original position so as to be able to absorb further shocks.

  • Patent number: 4463074
    Abstract: Radiation is directed toward a support through an ordered array of lateral walls to form interlaid radiation-exposed and shadowed microareas on the support. A first composition is then located on the support in either the shadowed or unshadowed microareas. At least one additional composition is then positioned on the support in laterally displaced microareas forming an interlaid pattern with the first microareas.

  • Patent number: 4441952
    Abstract: Method for constructing a forming structure for imparting a uniformly apertured three-dimensional pattern to a heated plastic material subjected to a fluid pressure differential while in contact with said forming structure. In a preferred embodiment, said forming structure is created by forming a substantially continuous pattern of apertures in a multiplicity of planar sheets, at least a portion of said sheets having aperture patterns which are concentrically aligned but dissimilar in size to one another. The sheets having said concentrically aligned aperture patterns are thereafter superposed upon one another and bonded together at contact points so as to form a stack exhibiting a three-dimensional continuum of capillary networks. A sufficient number of laminae are employed to ensure that said networks are of greater overall thickness than the maximum depth to which the plastic film is drawn when subjected to said fluid pressure differential.

  • Patent number: 4436585
    Abstract: Connection insulators having a plurality of insulating compartments for electrically isolating electrical connections formed from strips of insulating material of indeterminate length. In one embodiment, a first strip of insulating material is supplied to a securing station at a predetermined average rate of supply and a second strip of insulating material is supplied to a forming station at a predetermined average rate of supply greater than the predetermined average rate of supply of the first strip with the pliability of the second strip being enhanced by heating the strip for aiding the deformability characteristics of the second strip. The second strip of insulating material is deformed into predetermined patterns at the forming station and then moved into position adjacent to the first strip of insulating material at the securing station.

  • Patent number: 4435015
    Abstract: A composite underbody cushioning and ventilating structure of general use and especially useful as a seat pad for the occupants of vehicles, formed of two sheet members with padding material between them, one sheet member being of woven, fibrous decorative material designed for ready passage of air therethrough and the other sheet member being a formed plastic three-dimensional preferably air impervious sheet member that serves the multi-purposes of (a) spacing the sheet members apart for passage of ventilating air between them; (b) presenting an exterior surface that ventilates by lateral air movement and thermal current air movement within local areas of the member; (c) acting as a support for a body while contacting the body in measurably less than 50% of the area of the body; and (d) presenting an exterior surface having a decorative appearance. The present invention also involves the features of the formed plastic sheet member, per se.

  • Patent number: 4429012
    Abstract: A wood sheet-like product which comprises at least two sheets of wood and a pliable material bonded between the sheets. The wood and pliable material is bonded to form a unitary product and grooves through the wood sheets are spaced at intervals to facilitate bending of the product at the grooves. The sheet-like product is used to make wood honeycomb and corrugated wood by positioning grooves at predetermined locations on the product, bending the product into a certain configuration. In the case of honeycomb, adjacent strips of the product are adhered together in such a way as to form polygonal cells. To make corrugated wood one configuration has a series of high and low ridges secured to a facing skin. The methods of making the wood sheet-like product comprises inserting a pliable material between two sheets of wood bonding the sheets together and cutting a groove through the wood sheets but not through the pliable material.

  • Patent number: 4427474
    Abstract: A method and apparatus for the production of air cell cushioning material, for protective cushioning purposes in packaging or other purposes, with the air cell product being formed from flexible, single stratum sheet of low density, low melting point thermoplastic, such as low density polyethylene film. The method and apparatus include an arrangement for cooling an embossed film on a rotatable forming drum to a predetermined temperature range prior to applying a sealing laminating film to the cooled embossed film, and are such that the apparatus can be halted in its operation without injurious effects to any substantial amount of the air cell product being produced, and can be restarted to again commence production of the air cell product. The apparatus and method utilize clear thermoplastic single stratum film, and result in an effective air cell cushioning product which possesses extremely good clarity even after the heating and pressure steps utilized in the production of the product.
