Patent number: 6701971Abstract: Coated inflatable fabrics, more particularly airbags to which very low add-on amounts of coating have been applied, are provided which exhibit extremely low air permeabilities. The inventive fabrics are primarily for use in automotive restraint cushions which require low permeability characteristics (such as side curtain airbags). Traditionally, heavy, and thus expensive, coatings of compounds such as neoprene, silicones and the like, have been utilized to provide such required low permeability. The inventive fabric utilizes an inexpensive, very thin coating to provide such necessary low permeability levels. Thus, the inventive coated airbag possesses a coating of at most 3.0 ounces per square yard, most preferably about 0.8 ounces per square yard, and exhibits a leak-down time (a measurement of the time required for the entire amount of gas introduced within the airbag at peak pressure during inflation to escape the airbag at 10 psi) of at least 7 seconds.Type: GrantFiled: November 22, 2000Date of Patent: March 9, 2004Assignee: Mililken & CompanyInventors: John A.

The slices, all generally of a thickness, are placed on the flat bottom of a die within side walls. Adhesive is applied to the slices and the die is filled with a mixture of the binder and the filler. The die contents are hot pressed to achieve the required tile thickness. The tile is ejected from the die and then maintained at room temperature for not more than 72 hours. The face side of the tile is ground and the dimensions of the tile are brought within the required tolerances.Type: GrantFiled: November 30, 1998Date of Patent: February 13, 2001Assignee: Polymate Ltd.Inventors: Oleg Figovsky, Vladimir Teper

Patent number: 6156402Abstract: A wooden flooring strip having a wooden flooring strip, comprising a top surface and a base surface opposed to the top surface, the top surface and the base surface defining between them a predetermined thickness wood flooring material. The predetermined thickness wood flooring material includes a top surface zone adjacent the top surface and a base surface zone adjacent the base surface. The base surface zone has longitudinally-extending wood fibers which have been broken to an extent sufficient to relieve tension on the base surface and thereby increase the flexibility of the flooring strip for more closely adhering to a sub-floor. The top surface zone has longitudinally-extending wood fibers which have been broken to an extent sufficient to relieve tension on the top surface of the flooring strip and to equalize tension on the wood fibers adjacent both the top surface and base surface of the flooring strip.Type: GrantFiled: April 30, 1999Date of Patent: December 5, 2000Assignee: Triangle Pacific Corp.Inventor: William S. Smith

Patent number: 6106944Abstract: In the manufacture of a structural member comprising a thermoplastic composite core with an exterior reinforcing layer, the core member is initially extruded in the shape of a profile. The profile is then contacted with reinforcing fiber and resin to form the exterior reinforcing layer. The exterior thermosetting layer is cured to form a reinforcing layer. The structural member is preferably manufactured using a pultrusion method in which a tractor device is used to provide linear movement of the profile from the extrusion head to the exterior coating operation. The fiber-reinforced thermoset is coated on the entirety of the exterior of the profile or is applied only on a portion of the profile requiring reinforcement in a defined load-bearing direction. A preferred thermoplastic core comprises a polymer-fiber composite material.Type: GrantFiled: July 11, 1997Date of Patent: August 22, 2000Assignee: Andersen CorporationInventors: Kurt E. Heikkila, Anthony L. Garofalo

Patent number: 6098680Abstract: A method is used to make bamboo slats which are intended for use in making a blind. The method comprises a first step in which a bamboo stem is split into a plurality strips. The bamboo strips are barked, polished, and bleached before they are adhered side by side to form a base plate. A plurality of base plates are adhered in a stack to form a rectangular bamboo block having bamboo fibers which are arranged in an interlacing manner. The bamboo block is sliced into a plurality of bamboo slat, with each having bamboo fibers which are arranged in the interlacing manner.Type: GrantFiled: August 31, 1999Date of Patent: August 8, 2000Assignee: Nien Made Enterprise Co., LtdInventor: Ming Nien

Patent number: 6085813Abstract: A method for making hardwood or decorative plywood. The plywood includes a number plies including a back veneer, a face veneer, and a number of core and center plies. The method forms subunits of plies and stacks the discrete formed subunits to form a unit. The unit is processed to forms discrete hardwood panels. Subunits having different sets of plies are formed. The subunits are formed by sequencing the order of placement of the plies so that the face and back veneers do not touch the conveyor. This process enables line assembly of hardwood plywood. Without this sequencing, at least the back veneers would touch the conveyor subjecting the panel to aesthetic damage due to the nature of the outer veneers. This process also significantly reduced the labor necessary for forming the panels because numerous subunits can be formed simultaneously.Type: GrantFiled: October 30, 1998Date of Patent: July 11, 2000Assignee: Georgia-Pacific CorporationInventors: Gary E.

Patent number: 6051301Abstract: A reinforcement panel with a cellulose surface material improves adhesion of the panel to one or more wood segments in wood structural members such as laminated beams, wood I-beams, and trusses to provide a cellulose material-to-wood segment interface that withstands high shear stresses. The reinforcement panel is comprised of a plurality of reinforcement fibers that are preferably arranged parallel to one another and aligned with the longitudinal direction of the panel, and accordingly the wood structure. The fibers are maintained in position by a resin encasement that completely encloses the fibers. A cellulose surface material is impregnated with a polyester resin and adhesively connected to a first side of the panel. The first side of the panel is adhesively affixed to the wood structure at an area of high stress such that the surface material is sandwiched between the resin encasement of the panel and the wood structure. Thus, the panel provides improved adhesion.Type: GrantFiled: May 16, 1997Date of Patent: April 18, 2000Inventor: Daniel A. Tingley
