  • Patent number: 6723264
    Abstract: The biodegradable acting material is made from starch with various additives such as nucleators and plasticizer. The blowing agent used for foaming of the starch material may be alcohol or water. The material is made by mixing a charge of starch, nucleator and plasticizer to form a flowable mass which is then injected on the fly with the blowing agent, i.e. alcohol and/or water. Thereafter, the flowable mass is extruded through a dye and is either cooled to form a latent-foaming material or is allowed to expand into a foamed state. The starch which is used may be a corn starch, potato starch or the like.

  • Patent number: 6723265
    Abstract: A polymer of a kind different from a polyester in an amount within the range of 0.3 to 5.0% by weight based on the polyester is added to the polyester, and the resulting composition is melt-extruded from the same pack. The extruded filament group including polyester multi-filaments is cooled once to the glass transition temperature or below, and the filament group is subsequently divided into two groups. One of the filament groups in an opened state is subjected to non-contact heat treatment at an atmospheric temperature of 120° C. or above; however, the other filament group is kept in a state without being subjected to the heat treatment. The respective filament groups are then simultaneously taken off at a speed of 2500 m/min or above and subjected to doubling and mixing of the filaments.

  • Patent number: 6723266
    Abstract: A method and apparatus for making a pipe liner and the pipe liner itself. A thin walled pipe liner, after being provided cooled from a spool or extruded in tubular form and cooled, is deformed to a smaller cross section at ambient temperature. The pipe liner is then encased and held in its reduced cross section deformed shape by a protective sleeve which is co-extruded directly over the pipe liner. The sleeved pipe liner may then be wound on a drum for transport to a remote location. Ducts for water may pass through the pipe liner. Other ducts, for example, for fiber optics, may pass through the sleeve either within or outside of the deformed pipe liner.

  • Patent number: 6723271
    Abstract: A method of making a composite part includes the steps of placing a first section of a fibrous pre-form in a mold and infusing the first section of the fibrous pre-form with a resin so as to produce a resin-infused portion and a non-resin-infused portion. Next, the method includes coupling the non-resin-infused portion to a second section of the fibrous pre-form to create a coupled non-resin-infused portion. Then, the coupled non-resin-infused portion is infused with resin to create a second resin-infused portion and a second non-resin-infused portion. These steps are repeated to separately infuse different sections of the part until the part is complete. The corresponding apparatus preferably employs a rigid mold having a shape defining only a portion of the composite part to be made. And, the method is particularly adapted to making both cored and non-cored structures that are large or unconventionally shaped.
