  • Patent number: 9272301
    Abstract: Non-contact method and apparatus for Drying, Conditioning, Shaping and Manipulating of sheet fed Media. These functions are performed either on one side, or simultaneously or delayed one from the other on both sides, of the Media. For Drying, the energy applied is minimized to that necessary to supply latent heat of vaporization permitting use in, for example, low cost printers. No friction is introduced in the transport path enabling high speed, reliable Media transport. A region is established between Media and Platen wherein heat, support, and chemical or other processing may occur in a controlled way. Relatively few, inexpensive, and small parts are needed lowering the cost, energy, and space requirements for performing the various functions allowing for new applications in many fields. Media is supported a specific distance from a Platen by a balance of Fluid forces. The Media and the Platen bound a region in which forced convection greatly enhances process rates otherwise be limited by diffusion.

  • Publication number: 20140117573
    Abstract: A thermoplastic injection molding system and method of use is described for molding parts from heated plastics and other organic resins. The machine uses heat sources located along the barrel to heat the source material while an auger screw transports the source material in the barrel. This transport step does not shear the source material, nor does it use friction to produce the heat necessary to melt the source material. The material becomes substantially liquid or melted during the heating process, and the melted material is forced, by the auger screw, into a chamber whereupon a plunger, situated concentrically with the auger screw, injects the material from the chamber into a mold. Sensors located along the barrel and in the chamber ensure consistency between mold cycles. The controller dynamically adjusts the injection molding process to achieve more consistent and reliable molded parts.

  • Publication number: 20120306111
    Abstract: A method and apparatus for moving along a tube extrusion line. An extruded tube is pushed through the extrusion line, by means of pressure generated by an extruder, to a withdrawal unit that takes over further driving of the tube. In a first-moving along phase, in which the tube has not yet passed a sealing of a calibration cooling unit relative to the atmosphere, the latter is under atmospheric pressure. In a second phase, in which the tube has passed the sealing, the calibration and cooling unit is placed under underpressure. In the first phase, the tube is supported either by internal overpressure or by a mechanical inner guide. A support cylinder extends axially from a casing head of the extruder and extends coaxially into a calibration sleeve in a first section of the calibration and cooling unit. A support plate is disposed between the casing head and an inlet of the calibration sleeve and provides external support for a tube exiting the casing head.
