  • Patent number: 10981329
    Abstract: A powder sintering lamination apparatus forms a powder layer having a predetermined thickness from a fiber-containing resin powder supplied onto a shaping table using a flattening device. The apparatus irradiates a predetermined place of the powder layer on the shaping table with laser light from a laser light irradiation module, sinters the part of the powder layer irradiated with the laser light to form a solidified layer, and forms a three-dimensional shaped object on the shaping table by laminating a plurality of the solidified layers integrally with each other. The flattening device includes a first blade and a second blade that move in different directions. The movement track of the first blade on the shaping table orthogonally intersects with the movement track of the second blade on the shaping table. The first blade and the second blade move alternately on the shaping table.

  • Patent number: 7588668
    Abstract: A sputtering target assembly and method for bonding a sputtering target to a backing plate is disclosed. When insulatively bonding a sputtering target to a backing plate, it is necessary to ensure that the bonding material has good thermal conductivity so that the temperature of the target can be effectively controlled. It is also important to not have electrical conductivity through the bonding materials. In order to achieve both goals, it is beneficial to utilize an elastomer with diamond powder filler. Diamond power has very good thermal conductivity, and it also has very good dielectric strength. Diamond is a thermally effective and cost effective substitute for silver in insulative bonding.

  • Patent number: 5171614
    Abstract: A method of forming a dry, three dimensional block of sculptable material preferably involves the steps of painting the grains of a granular material, allowing the painted grains to dry, mixing a water resistant binder with the painted grains to form a slurry and hardening the slurry to form the block. The amount of binder added is selected to provide a block with a hardness between about 0.25 and 4.0 on the Mohs scale. The formed block has a wide variety of uses, including but not limited to use as a sculptable article, a sanding object, a sign or as a paving stone.

  • Patent number: 5069947
    Abstract: In a method for laminating a plastic web onto a plastic substrate, the web is moved past an adhesive coating station where one surface is coated with a mixture made of solvent and resin particles. The substrate is moved past a cleaning station, where a surface is also coated with a mixture made of solvent and resin. After the web and substrate pass through drying chambers, the coated surfaces are pressed together with rollers and heat is applied. The method is particularly suitable for laminating strips bearing a woodgrain pattern onto extruded thermoplastic members which are thereafter cut into segments for use in making prefabricated window systems.

  • Patent number: 4960481
    Abstract: A brush including a laminate having a handle end portion adapted for manual engagement, and an opposite head end portion; and a plurality of rows of bristles having end portions adhered between adjacent plies in the head end portion of the laminate and projecting outwardly. The brush is formed from pieces of oriented polymeric film, portions of which are adhered to individual plies to be incorporated in the laminate and have portions projecting from the plies separated into bristles before the plies are laminated to form the brush. Lamination is done by driving moisture out of pasteboard layers coated with dried water activatable adhesive by exposure to radio freqeuncy energy which activates the adhesive to form the laminate.

  • Patent number: 4851069
    Abstract: A process of making a liquid absorbing laminated structure comprising long lengths of absorptive tissues and an intermediate layer of absorptive particles is performed while the tissues are traveling in the direction of their lengths. A film of moistening liquid is transferred to a surface of a first tissue which is then supported in substantially horizontal position and showered with dry absorbent particles, which are rendered adhesive by absorption of the moistening liquid. A second tissue is superposed and the assembly is bonded together by passing it through the nip between a heated roller having a surface temperature of at least 110.degree. C. and a pressure roller. These rollers are pressed together at the nip by a pressure of at least 350 pounds per square inch and each has a surface hardness in excess of 90 Shore A Durometer.

  • Patent number: 4787949
    Abstract: A superabsorbent filter medium which is suitable for manufacturing accordian pleated filter cartridges at high production rates and low cost by using a rotary pleater or scoring machine rather than slower blade-type pleaters. The filter medium is a thin laminate of filter paper, superabsorbent resin powder, and tissue papper, rolled together under pressure and bonded with water vapor. Unlike other commercially available superabsorbent filter media laminates, this construction is thin and flexible enough to be rotary pleated at low cost.

  • Patent number: 4695343
    Abstract: Method and apparatus is provided for reinforcing a structural member of a vehicle body by the use of adhesively bonded together glass macrospheres of 3 to 9 mm. in diameter. The adhesive is not more than about 40% by weight of the mixture so that voids remain between the adjacent macrospheres to permit airflow through the reinforcement and the reinforced structural member upon curing adhesive. The adhesive may be curable at ambient temperature or may be a high temperature curable adhesive which is cured in a vehicle body paint curing over to bond the macropsheres to one another and to the structural member. The adhesion of the macrospheres to the structural member may be facilitated by an epoxy coated flexible sheet material lining the walls of the structural member. The adhesive coated macrospheres may be closely packed into the structural member by pouring or blowing.

  • Patent number: 4618388
    Abstract: A filter media for use in a filter employed to separate water and particulate material from a liquid to be purified, such as a hydrocarbon fuel. The filter media includes a porous material such as glass fiber having a density sufficient to provide the desired mechanical filtration and which carries a water insoluble, water-absorbing material as, for example, a starch-polyacrylonitrile graft copolymer. Also disclosed is a filter employing the media and a method of making the media.
