Abstract:
A fully contented floor module (10) is provided. The floor module includes a lower floor section (18) and a plurality of side walls (20) that define a cavity (28). An upper floor segment (24)′ is connected to the side walls. A mounting flange (26) extends from the upper floor segment (24) and is adhesively secured to the vehicle load bearing structure (12). The lower floor section (18), side walls (20), upper floor segment (24) and mounting flange (26) are integrally formed. A pivotal floor section (32) is pivotally secured to the upper floor segment (24). A seat (30) may be stowed in the cavity (28). Dampers, heat shields and underbody shields may also be secured to the floor module. The floor module may also include ductwork (44) and wiring raceways (46).
Abstract:
An apparatus for combines for the collection of threshed material discharged from the combine and automatically dumping the collected material when a predetermined weight of material is accumulated. The apparatus includes a threshed material collector attached to the combine for rotation about a horizontal axis that is closer to a forward end of the collector than a rearward end of the collector. The collector includes a plurality of horizontally spaced tines extending in a rearward direction and position to collect material discharged from the combine. A counter weight is attached to the collector for controlling the amount of material collected before the collector rotates under the weight of the collected material to a dumping position where the collected material is removed from the collector.
Abstract:
The present invention is a method to make an environmentally friendly polyurethane molded article (100) comprising at least 20 percent renewable materials and molded articles made therefrom. Specifically, the method provides for molding a polyurethane coated sandwich structure (40) comprising a honey comb core (30) having fiber reinforcing layers (10, 20) to provide an environmentally friendly polyurethane molded article with a desired shape such as an automobile load floor. The polyurethane coating is derived from a polyurethane—forming mixture comprising an isocyanate component and a polyol component. Specifically, the polyol component comprises one or more natural oil based polyol, preferably comprising at least one of a hydroxymethylated fatty acid or a hydroxymethylated fatty acid (methyl) ester.
Abstract:
A process for producing resilient, flexible polyurethane foams that function well in noise and vibration absorption applications for vehicle applications that are made from a blend of polyols (i) and an isocyanate (ii), wherein the blend of polyols (i) comprises a mixture of polyether polyols (i.a) that each has a hydroxyl equivalent weight of from 1200 to 3000 and at least 70% primary hydroxyl groups, from 5 to 80% by weight of the ethylene oxide-capped polypropylene oxides are nominally difunctional, from 0.5 to 20% by weight of the ethylene oxide-capped polypropylene oxides have a nominal functionality of four or higher, and the balance of the ethylene oxide-capped polypropylene oxides, but not less than 1.5% by weight thereof, are nominally trifunctional; an autocatalytic polyol (i.b) having a functionality in the range of 2 to 8 and a hydroxyl number in the range of 15 to 200, wherein said autocatalytic polyol compound comprising at least one tertiary amine group; and a low unsaturation polyol (i.c) having a functionality equal to or greater than 2, a hydroxyl equivalent weight of from 1800 to 2800, and a total unsaturation value of equal to or less than 0.06 meq/g.
Abstract:
A floor module (10) and method of inserting a floor module are provided. The floor module comprises a floor section (18) and a pair of side walls (20) at the peripheral edges of the floor section. The side walls (14) are adhesively secured to the side rails of the vehicle load bearing structure (12). A damper (30) is applied to the bottom of the floor section. The floor module (10) is inserted into the vehicle during the assembly process. Heat activated adhesives (24, 28) secure the floor module to the loading bearing structure (12) of the vehicle during an e-coating process.
Abstract:
A polyurea-polymer formulation suitable for preparing a molded polyurea polymer includes a polyisocyanate, an isocyanate-reactive material, and a fatty-acid ester. The fatty-acid ester is present in an amount effective for providing a molded polyurea polymer prepared from the formulation with blister resistance such that when the molded polyurea polymer is exposed to moisture and a temperature of at least about 350° F. (177° C.), the molded polyurea polymer is substantially free of blisters. A fatty-acid ester suitable for use with these formulations can be natural or synthetic, and one example includes jojoba oil. A polyurea-polymer formulation can also include other components known to be useful with polyurea polymers such as fillers, catalysts, surfactants, and polyepoxides. A molded polyurea polymer can be prepared from a polyurea-polymer formulation. One method suitable for preparing a molded polyurea polymer includes reaction injection molding.
Abstract:
A polyurethane composition useful for the manufacture of an elastomeric part is provided. The polyurethane composition comprises a polyisocyanate prepolymer and an active hydrogen containing compound, wherein from about 10 to about 60 percent by weight of the composition is a butylene oxide adduct and from about 70 to about 100 percent of the butylene oxide adduct is present in the polyisocyanate prepolymer. A method for preparing a polyurethane polymer from the polyurethane composition is also provided. Also, a method for preparing a polyurethane article from the polyurethane composition is provided.
