  • Patent number: 10137607
    Abstract: Methods and apparatus for curing curved cylinder-like workpieces (e.g., in the shape of a half or full barrel) made of composite material, such as nacelle honeycomb core composite sandwich structures. These methods enable tailored curing of composite nacelle structures, to significantly reduce capital cost and fabrication cycle time. In lieu of an autoclave or oven, a pressurized ring-shaped cure volume is defined by a partitioned enclosure that mimics the cylinder-like shape of the composite nacelle structure with only limited clearance (e.g., a partitioned enclosure comprising inner and outer concentric cylinder-like walls). A tool (e.g., a mandrel) and at least one composite nacelle structure supported thereon are placed in the cure volume for curing. Integrally heated tooling, optionally in combination with other heating methods, such as infrared heaters, is utilized to provide the temperature profile necessary for cure.

  • Patent number: 8939753
    Abstract: The high straightness arrow in the present invention is designed to improve the straightness of the archery arrow by adopting new manufacturing technique and method. Chamber and post are made of dissimilar metals and the chamber includes a wall that creates an external housing and defines an internal airspace. Once the post with shaft is positioned through chamber, nuts are tightened securely, forming an assembly, to straighten post. Due to the different coefficients of thermal expansion of chamber and post, when they are heated simultaneously, the chamber expands more than the post, creating a natural tension along post which results in a near perfectly straight shaft. As the assembly cools, the post and chamber return to their original length, yet the shaft retains its straightened form and thus this manufacturing process yields an arrow shaft that is straighter than shafts made of the same materials but with a traditional manufacturing technique.

  • Patent number: 8932043
    Abstract: Disclosed is a plastic trim reclaim process that recycles otherwise wasted trim into for reuse or densified composite bricks for resale. The device combines four sections to process trim scrap from a typical plastic extrusion process. The four sections comprise an input and feed section, a grinding and pre-sizing section, a compaction and sizing section, and a repelletizing and recovery section. The final product takes one of two forms: a compacted plastic brick or pellet-sized beads that can be directly reused in a new extrusion process. The compaction and sizing section utilizes a heating chamber and ram to force ground trim through an extruder, which is then cut into sections to form brick. The repelletizing and recovery section utilizes an extrusion process that feeds into a cutting plate, whereafter the sized pellets are cooled to solidify their structure prior to being vacuum transported into a container for reuse.

  • Publication number: 20130009343
    Abstract: A method and an apparatus simultaneously produces a plurality of billets of a formable material with a press, which includes a plate-like female die, provided with nozzles in the form of continuous holes, and also a rotating hub provided with radially disposed rollers that are pressed onto the female die. The method provides that the female die is heated to a temperature above the boiling temperature of the moisture contained in the formable material, and in this way the material pressed through the hole-like nozzles of the female die is dried. The apparatus includes the female die having two plates resting closely and tightly against one another, and in at least one of the plates, a conduit for a heating medium or coolant is made in the surface facing toward the other plate.

  • Patent number: 8342835
    Abstract: A seal ring whose abutment joint portion is opened is fitted into an annular gap while the abutment joint portion is substantially closed. The annular gap is formed between an inner circumferential surface of a hole portion provided in an outer circumferential jig and an outer circumferential surface of an inner circumferential jig disposed in the hole portion, and has a heating region and a cooling region. The seal ring is passed through the heating region and then passed through the cooling region in the annular gap. The outer circumferential jig and the inner circumferential jig are maintained at a constant temperature higher than a glass transition temperature of a resin material for the seal ring in the heating region, and maintained at a constant temperature lower than the glass transition temperature of the resin material for the seal ring in the cooling region.

  • Patent number: 8333582
    Abstract: A method and machine for sealing at least one cut edge of a foam board is disclosed. The foam board has a top surface, a bottom surface and at least one cut edge extending between the top surface and the bottom surface. The cut edge is passed over a heated roller to soften the edge and then passed over a second roller having a temperature that is lower than the temperature of the first roller which seals the edge. The cut edge may be milled to square the edge relative to the top and bottom of the board before the cut edge is passed over the heated roller. Additional pairs of rollers may be provided to seal the top surface and the bottom surface of the foam board.

  • Patent number: 8226393
    Abstract: The system for vacuum formation of a dental appliance is a fully automated vacuum formation machine for dental appliances, such as retainers and the like. The system includes a base having a perforated top vacuum plate in communication with a vacuum source. A heating unit is positioned above the perforated top vacuum plate, and a controller is in communication with the heating unit and the vacuum source for selective actuation thereof. A holder releasably receives a thermoplastic plate. The holder is selectively positionable vertically over the perforated top vacuum plate and a dental impression cast mounted thereon. The holder is positioned by a linear actuator or the like, in communication with the controller. A sensor is positioned adjacent the perforated top vacuum plate for measuring the thermoplastic plate's thickness as it is molded about the dental impression cast, and is communication with the controller.

  • Patent number: 8215943
    Abstract: A heat-transfer label assembly and an apparatus for applying heat-transfer labels. In a preferred embodiment, the heat-transfer label assembly includes a support. A plurality of labels are positioned over the support for transfer from the support to an article, each of the labels including an ink design. A plurality of spacers are positioned over the support but not over the label, the spacers not being transferable with the labels from the support to an article. The distance from the top of the spacers to the support exceeds the distance from the top of the labels to the support so that, when the assembly is wound into a roll, the labels do not come into contact with the bottom surface of an underlying portion of the support. In a preferred embodiment, the apparatus for applying heat-transfer labels includes a pad, a die-mark reduction device on the pad, a heated die positioned over the pad, and a motor for moving the heated die into and out of engagement with the die-mark reduction device.

  • Publication number: 20120085604
    Abstract: A process for manufacturing brake linings that comprises the stage of cold heating of the friction material and compaction by using a punch with a surface having sinuosity (10) that presses the friction material (100) forming undulations on the surface (110), and the stage of heat pre-molding of the friction material at a temperature lower than that of the resin polymerization for better shaping of the pre-mold, because the resin adheres in a form of a thin layer (film) onto the entire surface which defines a better shape of the pre-mold and, also, provides the material with the heat closer to that of polymerization, which ensures a better quality for the product, and then, the stage of heat molding of the pre-formed friction material and compaction by using a curve-like punch (20). Additionally, this invention discloses an obtained product that comprises friction material with bigger or smaller interspersed oriented density areas.
