Abstract: A roller is connected to a harvesting platform for movement with a combine over a ground surface in a direction of travel. The roller includes a first portion defining a first diameter and including a first material, and a second portion defining a second diameter and including a second material. The second diameter is greater than the first diameter. The second portion substantially surrounds the first portion, the second material has different material properties than the first material. The roller extends in the direction of travel and rotates about a second axis which extends generally parallel to the direction of travel.

Abstract: An air bag which is light and pliable to be compactly housed and excellent in durability against a load applied thereto, upon the actuation of air bag, and long term aging, which is formed of two woven fabrics interwoven with each other to be a bag-shaped body, each composed of polyamide type synthetic fiber yarns containing copper compounds in a range from 30 to 200 ppm estimated in term of copper or cut pieces of the fabric sewn together to be a three-dimensional shape, the fabric having a product of a total fineness of warp or weft multiplied by a weave density of 16000 decitex·ends/2.54 cm or less, a load at 15% elongation in a range from 3 to 35 N/%/2.54 cm and a tensile work at break in a range from 7000 to 30000 N·%/2.54 cm. This air bag may be applicable to a driver's seat, a passenger's seat, and to side impact protection in a vehicle.

Abstract: An article useful as an architectural fabric consisting of (a) a layer of fabric having a first surface and a second surface made of polytetrafluoroethylene fibers; and (b) a fluoropolymer coating disposed on at least the first surface of the fabric.

Abstract: A method of forming a nonwoven fabric suitable for metal-finishing buffing operations includes providing a precursor web comprising polyester, staple length fibers, with hydroentanglement of the web effected to impart desired physical characteristics. Hydroentanglement is effected on a three-dimensional, image transfer device having an array of three-dimensional surface elements for patterning the fabric which is formed. Application of a binder composition lends desired durability to the fabric, with the binder composition preferably including a melamine polymeric composition to achieve the desired strength and abrasion resistance.

Abstract: A fiber reinforced composite structure and method for fabricating the composite, are described wherein four sets of mechanically flexible fibers are interwoven in a three-dimensional woven structure wherein each fiber is woven through the structure generally along one of the four directions defined generally parallel to a body diagonal of a cube, and wherein the woven structure is impregnated with polymeric, metallic or ceramic matrix material to form a composite material which is braced against deformation by shear applied in any orientation.
