    Abstract: An apparatus and process for depositing slurry upon a moving forming web. The apparatus includes a pivotally mounted headbox for depositing slurry from the inner bottom surface of the headbox down an inclined spillway as a continuous curtain onto a moving web. The headbox is mounted transverse to the direction of travel of the moving web. The headbox also has vertical edge boards, including a headbox back edge board and two opposed headbox side edgeboards, on three respective sides of the headbox to prevent slurry from spilling over the sides and back of the headbox. The headbox is supplied with slurry from a slurry mixer by a feed line mounted on a reciprocating trolley which moves, transverse to the direction of travel of the moving web, back and forth along the length of the headbox.

    Abstract: A very thin inner layer composed of a polymer chosen for its barrier and/or inertness properties is fabricated within a container preform constructed mainly from another polymer, or a structure of polymers. The inner layer on the preform is produced either by a controlled coating method involving coating of the injection mold core rod prior to injection molding or by a coating applied directly to the preform after injection molding. This enables both inner and main layers to be brought together at a time when the interface between them is molten. A tie layer can be employed, when desirable, to enable the layers to be combined without melting the layer interface.

    Abstract: An adhesive viscous liquid screed for dispensing a uniform thickness of an initially viscous liquid material onto a planar work surface in order to produce a film of predetermined thickness, length and width. The screed engages a planar horizontal application surface and a reservoir is filled with a liquid adhesive. As the screed is propelled forward along the application surface, the pressure on the adhesive due to gravity causes it to be forced out of the reservoir and through a first release orifice, thereby depositing a thin film of liquid adhesive. The height of the film is determined by the distance between the application surface and the bottom surface of a rib defining the release orifice and the width of the film is determined by the distance between the substantially vertical sides of the first release orifice.

  • Patent number: 5145527
    Abstract: Apparatus particularly adapted for applying foamed treating liquor to a flat width of a traveling non-woven textile substrate includes a longitudinal tubular foam distribution nozzle one side of which has a plurality of closely-spaced staggered apertures for engaging and applying pressurized foam widthwise across the substrate and a driven drum opposed to the nozzle engaging widthwise the opposite side of the substrate for imparting traveling movement to the substrate. The drum and nozzle cooperate to compress the substrate therebetween in covering relation over the apertures to prevent lateral escape of the foam therefrom and to confine the emission of foam therethrough, thereby to uniformly control foam application across the substrate width as it travels by the nozzle. Limited contact of the apparatus with the substrate prevents frictional pulling and structural damage thereto. The drum is perforated for escape of the air component of the foam and to enhance foam penetration of the substrate.

  • Patent number: 5099090
    Abstract: An apparatus and method are disclosed for preparing electrically conductive traces on a circuit board using an additive technology. The traces are directly written in a serial process with each trace being able to be individually insulated. The apparatus includes an extrusion element for extruding a first material and a stage. The stage is for holding the extrusion element and the circuit board in relative proximity and for producing relative motion between the extrusion element and the circuit board in order to extrude the first material onto the surface of the circuit board along preselected paths to produce the electrically conductive traces. According to the method of invention, a first polymerizable material is extruded onto a circuit substrate support along preselected paths to form traces, and the first polymerizable material is polymerized, the first polymerizable material being conductive after polymerization.

  • Patent number: 5085891
    Abstract: An edge sealing apparatus for composite boards comprises a heatable iron body having a bottom, presser surface formed with a shape or profile which conforms to that of the edge of the composite board to be sealed. In the method of edge sealing, the iron body mounts a slot nozzle formed with a discharge outlet having the same profile as the iron body and the edge of the board. The slot nozzle receives a sealing material such as hot melt thermoplastic adhesive from a dispensing device, and is effective to apply a coating of the hot melt adhesive along the entire surface area of the profile of the board edge. Immediately after the hot melt adhesive is applied to the edge of the board, the presser surface of the heated iron body presses or fuses such material therein to provide good penetration into the board edge and thus obtain a substantially complete seal.

  • Patent number: 5052338
    Abstract: A syringe or other suitable dispensing device is coupled to conventional controls for dispensing viscous material such as adhesives or solder paste through a tip thereof. The syringe is supported on a motor driven carriage for movement along a Z axis in response to height control signals. A camera also mounted on the carriage generates output signals representative of an image of the surface of a workpiece such as a PC board. Circuity processes the output signals from the camera to determine when the image is maximally in focus and generates the height control signals necessary to maintain the tip of the syringe a predetermined constant height above the surface of PC board. This ensures the dispensing of uniform balls of solder paste or adhesive at various locations on the PC board despite warpage in the board.

  • Patent number: RE34561
    Abstract: A system for applying .[.one-part thermal-cure.]. .Iadd.fluent .Iaddend.material, such as structural epoxy, includes apparatus for heating or cooling the epoxy to a temperature above or below ambient. A spirally coiled tube is suspended within a hollow enclosure by tube end fittings extending from axially opposed ends of the tube. An electrical heater and temperature sensor extend from opposed enclosure ends into the tube coils approximately centrally of the enclosure. The enclosure is filled with a heat transfer fluid that surrounds the coiled tubing. The fluid is connected through an inlet and outlet in the enclosure endwalls for circulation externally of the enclosure through a fluid chiller. A microprocessor-base controller receives input signals from the temperature sensor and a temperature adjustment mechanism, and provides outputs to the heater chiller and heater-exchange fluid pump and circulation valve, and to alarm mechanisms for indicating a high-temperature or low-temperature alarm condition.
