| 20080236722 | Fibrous product and method and apparatus for making the product - A nonwoven fibrous insulation product has at least a bi-modal fiber diameter distribution designed to provide the product with selected thermal insulating and physical performance properties that are affected by fiber diameter such as rigidity and recovery properties. The product is made by: forming two or more fiber groupings that each have a selected fiber diameter distribution with a selected mean fiber diameter wherein the selected fiber diameter distributions of the fiber groupings differ from each other. The fibers of the fiber groupings are intermingled and entangled together in selected percentages by weight to form a product with a selected density and thickness that exhibits selected product performance properties based on the properties of the fiber groupings and the relative percentages by weight of the fiber groupings. | 10-02-2008 |
| 20100252174 | TYRE BALANCING COMPOSITIONS - The invention relates to tyre balancing compositions having improved balancing properties comprise a visco-plastic gel and solid bodies having an average smallest dimension in the range of 0.5-5 mm; preferably 1-4 mm, more preferably around 3 mm. When applied in a layer to the inside of a motor vehicle tyre, the compositions act by allowing the solid bodies move through the gel and to concentrate in areas to counteract 10 imbalances. The solid bodies preferably have an average ratio a between their smallest and their largest dimension of α≦2, more preferably α≦1.5, especially around 1. The visco-plastic gel preferably has a storage modulus (G′) between 1000 Pa and 25000 Pa at 22° C., a loss modulus (G″) smaller than the storage modulus, and a critical yield stress above 3 Pa at 22° C. The bodies may be shaped as prolate or oblate ellipsoids, cylinders, 15 rectangular paralleipipeds, or spheres, or mixtures of such bodies; they may have an apparent specific gravity in the range of 500-3000 kg/m | 10-07-2010 |
| 20110088829 | METHOD FOR MANUFACTURING FIELD EMISSION CATHODE - A method for manufacturing a field emission cathode is provided. A carbon nanotube array formed on a substrate in a container and a prepolymer are provided. The prepolymer is put into the container settled for a period of over 30 minutes to fill in clearances of the carbon nanotube array, and part of the prepolymer is covering a top end of the carbon nanotube array. The carbon nanotube array is rotated at a speed to push the part of the prepolymer into the clearances of the carbon nanotube array and a prepolymer film in the carbon nanotube array is obtained. The prepolymer film is then polymerized to form a polymer film. | 04-21-2011 |

| 20110297296 | ROTOCAST COMPOSITE HYBRID PROCESS FOR MOLDING COMPOSITE PARTS - A rotocast composite hybrid method for efficiently making strong but lightweight parts. The method includes filling a mold with a volume of resin through an access port and then sealing the access port by positioning a lid over the access port. The method includes mounting the mold in a rotocasting machine and then operating the rotocasting machine to rotate the mold about two orthogonal axes until a layer of the resin is applied uniformly over an inner surface of the mold to form an outer wall of a part. The method includes removing the lid and then applying a reinforcement material (e.g., sheets of woven fiberglass) to an inner surface of the outer wall of the part through the access port. The applying of the reinforcement material also involves wet layup such as by binding the reinforcement material to the inner surface by applying additional resin to the reinforcement material. | 12-08-2011 |
| 20130233465 | SPIN FORMED CATALYST - A catalytic device and method for forming a catalytic device are described. The devices and methods described can be used for emissions systems in heavy duty diesel engines. In particular, a method of spin forming a catalytic device generally includes disposing a mat about an outer surface of a catalyst substrate and inserting the catalyst substrate and mat inside a shell. The mat is between the shell and the catalyst substrate. The shell, catalyst substrate, and mat can be spin formed into at least a generally elliptical shape but generally other than a circle shape. | 09-12-2013 |
