  • Patent number: 6723424
    Abstract: A molded article such as a floor tile is made from recycled carpet waste which includes a polyvinyl chloride component in the backing material and fiber component having a melting point above the melting point of polyvinyl chloride. A mixture of the recycled carpet material is shredded and additional polyvinyl chloride is fed to an extruder where the polyvinyl chloride is melted without melting the carpet fibers. The resulting mixture is discharged and molded, such as by injection molding, to form a molded product. The molded product includes a continuous matrix of polyvinyl chloride having recycled carpet fibers uniformly dispersed therein. The molded article contains about 45% to about 85% of polyvinyl chloride, about 5% to about 20% of recycled carpet fibers, up to about 5% of a plasticizer and up to about 5% of an ethylene copolymer by weight based on the total weight of the product.

  • Patent number: 6720044
    Abstract: The invention relates to pharmaceutical closures for containers made of flexible polyolefinic materials which are suitable to be filled with parentally administrable fluids prior to their sealing and sterilization. The polyolefinic closures have an excellent resealing capacity after being penetrated by a piercing device for establishing fluid communication with the container, even after multiple entries into the container.

  • Patent number: 6713153
    Abstract: Flat strips cut from discarded tires are stacked and stored as bulk rubber on pallets for easy handling, transport by fork lift trucks and storage in outside compacted storage space without accumulating water where mosquitos can breed. Typically flat rectangular longitudinal tread strips are folded and stacked in a plurality of abutting stacks about five feet high for rubber-to-rubber engagement in configurations extending substantially to opposite edges of a pallet platform, thus storing about a ton of bulk rubber per pallet. The pallets then may be transported and stored in compact stacks at outside locations without accumulating water and breeding mosquitos.

  • Patent number: 6706132
    Abstract: Methods for fabricating laminations to form structural elements of predetermined shapes (120, 220, 420, 520, 620) are provided. Laminations include parts (22, 24) fabricated from the tread portion (42) of discarded rubber tires. The parts are typically arranged in layers with various relationships therebetween. The parts are pressed to remove all voids therebetween causing dynamic tension which creates rigidity and then bonded with methods including vulcanization, chemical vulcanization, epoxy and adhesive.

  • Patent number: 6663929
    Abstract: A label having a thermoplastic polymer film and an ink layer formed on at least one surface thereof, the ink layer being removable in alkaline hot water, can easily be recycled after separated or without being separated from the bottle into polymer pellets with improved purity. The recycled polymer pellets are extremely suitable for the effective use of resources because they contain substantially no ink and can therefore find various applications.

  • Patent number: 6641749
    Abstract: A method for manufacturing a tire retardant cellulose insulation with reduced density and reduced settling. The method consists of adding a material, the fibers of which have a positive electrostatic charge, onto a shredded newspaper base either before or after the addition of a pre-coat, consisting of a mixture of limestone and an antistat. A fire retardant agent is then added and the materials are ground in a finish mill. The newspaper fibers become positioned at an angle to the paper pieces, increasing the distance between the paper pieces, thereby lowering the density of the cellulose. Fibers such as ground cardboard, wood mulch, sawdust, and fiberglass fibers are examples of materials with electrostatically positively charged fibers.

  • Patent number: 6641750
    Abstract: An improved fire retardant cellulose insulation with reduced density and reduced settling. A method consists of adding a material, the fibers of which have a positive electrostatic charge, is added onto a shredded newspaper base either before or after the addition of a pre-coat, consisting of a mixture of an inorganic, non-hygroscopic powder and an antistat. A fire retardant agent is then added and the materials are ground in a finish mill. The newspaper fibers become positioned at an angle to the paper pieces, increasing the distance between the paper pieces, thereby lowering the density of the cellulose. Increasing the amount of antistat will decrease settling at the expense of increasing density. Adding water to the insulation system will neutralize static electricity and minimize settling. Fibers such as ground cardboard, wood mulch, sawdust, and fiberglass fibers are examples of materials with electrostatically positively charged fibers.
