  • Patent number: 10161727
    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.

  • Publication number: 20150076738
    Abstract: A mould for forming a wind turbine blade is formed in two halves, each half 1a comprising a sandwich structure of a perforated outer layer, an inner aluminium honeycomb structure and an inner impermeable heat-conducting layer. An article in the form of a mat of glass fibre impregnated with epoxy resin is placed in the mould. A supply chamber 6 supplies heated pressurised air to the mould which passes into the honeycomb core of the mould through the perforated outer layer, and back through the outer layer into two exhaust chambers 7. A row of supply conduits 13 and exhaust conduits 16 connect the exhaust chambers 7 to the supply chamber 6. The air in each conduit 13, 16 is heated by a respective heat exchanger 18 supplied with heated water 9. The heated air cures the epoxy resin, and the mould is then cooled by supplying cold water to the heat exchangers 18, which, in turn cools the air supplied to the mould.

  • Patent number: 8734609
    Abstract: A process for continuous manufacturing of moisture-curable polyurethane formulations used as sealants and adhesives. The process is characterized by the fact that the reactive components are introduced independently, and without the need for a prepolymer, to a mixer. Solid or liquid raw materials can be either pre-blended or fed directly to the mixer, a twin-screw extruder, which provides the requisite energy to homogenously mix the raw materials and drive the chemical reaction. The process is designed so that the extruder barrel and screw allow variable feed addition and heat exchange down the length of the machine. This allows various operations to be performed at different points in the extruder, including reaction, dispersive mixing, distributive mixing and devolitization.

    Abstract: A method and apparatus for underwater pelletizing and subsequent drying of crystallizing polymers to crystallize the polymer pellets without subsequent heating is shown in FIG. 5. High velocity air or other inert gas is injected into the water and pellet slurry line (120) toward the dryer near the pelletizer exit (102) at a flow rate of from about 100 to about 175 m3/hour, or more. Such high-speed air movement forms a vapor mist with the water and significantly increases the speed of the pellets into and out of the dryer such that the polymer pellets leave the dryer with sufficient latent heat to cause self-crystallization within the pellets. A valve mechanism in the slurry line (150) after the gas injection further regulates the pellet residence time and a vibrating conveyor after the dryer helps the pellets to achieve the desired level of crystallinity and to avoid agglomeration.

  • Patent number: 8012392
    Abstract: Methods for cooling golf ball cores are provided. The methods involve passing a matrix of hot golf ball cores through a die plate to separate individual golf ball cores from the matrix. The die plate has a plurality of holes and each hole is sized to allow a single golf ball core to pass there through. A post-cure unit is arranged to receive the hot cores for additional curing and cross-linking. The hot, cured golf ball cores are then passed through a cooling section where high velocity air is passed over the golf ball cores to achieve the desired level of cooling. The cooling section may contain a fan assembly including an air diffuser to provide sufficient air flow coverage. The cooled golf ball cores may be delivered to a pneumatic delivery system for additional processing.

  • Patent number: 7959840
    Abstract: A method of constructing a shaft seal assembly includes attaching a PTFE seal element to an outer metal case and disposing a bore of the PTFE seal element onto a mandrel. Then, heating the PTFE seal element while on the mandrel. Further, cooling the PTFE seal element while on the mandrel and, removing the shaft seal assembly from the mandrel. The resulting seal element provides a reliable seal against a running surface of a shaft in use, while at the same time producing low running torque against the running surface of the shaft. Further, a minimal axial push force is required to install the shaft seal assembly onto the shaft, thereby reducing the potential of damage to the seal element or inversion of the seal element during installation.

  • Patent number: 7790081
    Abstract: A process producing an in-mold coated molded product. The process molds a thermoplastic resin material under a mold-clamping pressure in a mold including a fixed mold part and a movable mold part each heated at a predetermined temperature, separates the fixed mold part and the movable mold part when the molded material surface is solidified such that it is durable to a pressure of injection and flow of a coating agent, and injects the coating agent containing a thermosetting resin material between an inner surface of the mold and the molded product obtained. The process also coats the molded product surface with the coating agent as the mold is re-clamped after injecting the coating agent, takes out the molded product coated with the coating agent when the coating agent is cured such that it is neither peeled off nor cracked by opening the mold, and re-heats the molded product after taking it out.

  • Patent number: 7744789
    Abstract: Finite element analysis or thermocouple probes are used to determine the state of cure for each zone of a non-uniform, thick rubber article, such as a large tire or a tread for a tire. From this knowledge of those cure-limiting zones, heat transfer elements are added to the mold to enhance the transfer of heat into these cure-limiting zones and to provide a more optimum cure. The use of heat transfer pins and/or mini-sipes are an efficient and practical means of reducing total cure time in the press and optimizing cure state without substantially affecting the performance of the article such as the tire. Reductions in cure time of 10% or more are demonstrated.

  • Patent number: 7744805
    Abstract: A mold for forming, molding or welding thermoplastic tubing extends through the aperture of an apertured spool supporting an RF energized coil to inductively heat a center section of the mold. A source of air is channeled through a manifold to flow about the center section of the mold and through the space between the mold and the aperture in the spool to rapidly cool the mold. Thermal chokes on each side of the center section of the mold impede heat transfer and a heat sink connected to each thermal choke serves to dissipate any heat build up. The spool may be translated along the center section of the mold to a predetermined location commensurate with a predetermined heat profile. The mold includes a passageway extending therethrough for receiving the tubing; by appropriate dimensioning, the passageway will accommodate the use of a mandrel to support the tubing to be formed, molded or welded.
