Publication number: 20020125603Abstract: In a pultrusion device for producing continuous length sections prepared from thermoplastic resins reinforced with long fibers, the vertical angle (&agr;) of an upstream conical surface of a conical portion, which constitutes a shaping nozzle perforated through the downstream end wall of the device ranges from 15 to 35 degrees and the shaping nozzle has a land portion having a length of 1 to 5 mm in the downstream area subsequent to the upstream conical surface. According to this pultrusion device for producing continuous length sections prepared from thermoplastic resins reinforced with long fibers, the long fibers never undergo any breakage nor fluffing during the opening treatment and this accordingly leads to the substantial reduction of pill-formation.Type: ApplicationFiled: March 7, 2001Publication date: September 12, 2002Applicant: Chisso CorporationInventors: Yasuhiro Sakai, Rikio Yonaiyama

Patent number: 6428727Abstract: The present disclosure describes a process and an apparatus for delivery of plastic at a viscosity and in the required quantity suitable for compression molding of large, and often odd shaped three-dimensional products, such as large automotive body parts and large appliance parts, etc. These products may consist of plastic only, or may require additional layers of other plastics or even other materials such as woven cloth, inserted into the cavity before molding. The purpose of this invention is to provide a process and apparatus for use with a compression molding machine to supply plastic to a mold cavity, at a number of suitable locations, and in appropriate quantity at each location as required by product shape and thickness. The apparatus and process includes a delivery head which is mounted on rails attached to the machine clamp or the mold cavity, and a connection between the injection unit of the molding machine.Type: GrantFiled: February 17, 2000Date of Patent: August 6, 2002Assignee: The Elizabeth and Sandor Valyi Foundation, Inc.Inventor: Herbert Rees

Patent number: 6352657Abstract: A continuous process is used to make concrete building products with an expanded polystyrene core. The expanded polystyrene is fed into the inlet of an elongated guiding channel which has a longitudinally split mold. The expanded polystyrene is guided along the guiding channel without any means for pulling the expanded polystyrene. Concrete is then pumped into the split mold first through an first aperture in a first mold section of the split mold and then through another aperture, in a second mold section of the split mold, so that the concrete is coated on at least two opposing sides of the expanded polystyrene.Type: GrantFiled: February 3, 2000Date of Patent: March 5, 2002Assignee: 888804 Ontario LimitedInventors: Robert Veldhuis, Lubo Krizik
