Patent number: 5904885Abstract: A process for recycling rubber, elastomers, and thermoset materials in which the material to be recycled is pulverized in a manner which maintains the chemical composition of the material, producing a powder. The powder is introduced into a mold which is heated to a temperature of at least about 200.degree. C. and a compression force of at least about 10 tons is applied to the powder for a period of at least one hour, resulting in formation of a single piece of the rubber, elastomeric, or thermoset material, with no change in chemical structure.Type: GrantFiled: December 4, 1997Date of Patent: May 18, 1999Assignee: Illinois Institute of TechnologyInventors: Hamid Arastoopour, Daniel A.

Patent number: 5895622Abstract: A composite manufacturing system moves a multi-fiber tow through a processing space. A resin particle source provides particles to the space. This source may include an airstream entrained with particles which is discharged into the space through an orifice; the airstream diverging as it enters the space. An electrode is disposed in the space to electrostatically charge the particles and facilitate deposition of the charged particles on the tow. In one embodiment, the electrode includes a corona wire disposed proximate to the tow to provide a generally cylindrical charging region. An electric field useful to direct deposition of the particles may be generated by appropriately shaping a wire electrode and orienting it in a predetermined manner relative to the tow. After the particles are deposited, a fixation unit may be used to at least partially melt the deposited particles. A processing stage may be included which has a pair of surfaces configured to heat and compress the tow therebetween.Type: GrantFiled: April 7, 1997Date of Patent: April 20, 1999Assignee: Purdue Research FoundationInventors: Karthik Ramani, Daniel Edward Woolard, Mark Stephen Duvall

Patent number: 5879596Abstract: A process for making polyurethaneureas using cryogenic mixing is provided. Such polyurethaneureas are useful for making spandex and, ultimately, various types of clothing. The process involves cooling an isocyanate prepolymer or the like to a temperature of less than about -100.degree. C., forming a powder from the isocyanate prepolymer, adding at least one chain extender and/or chain terminator, and warming the powder to at least about room temperature to produce a polyurethaneurea. Such polyurethaneureas are useful for making spandex and, ultimately, various types of clothing.Type: GrantFiled: July 15, 1997Date of Patent: March 9, 1999Assignee: E. I. du Pont de Nemours and CompanyInventor: David H. Roach

Patent number: 5795856Abstract: The method for producing detergent particles having a high bulk density, the method being characterized by mixing granulated detergent particles having a bulk density of from 500 to 1,000 g/liter, while applying a shearing force to particles caused by a contact of the particles with each other in a mixer. According to the production method using a drum mixer of the present invention, it is possible to increase the bulk density of the detergent particles by 50 to 200 g/liter, wherein the granulated detergent particles or that of the granulated detergent particles subjected to a treatment of increasing bulk density by conventional methods have a bulk density of from 500 to 1,000 g/liter.Type: GrantFiled: September 27, 1996Date of Patent: August 18, 1998Assignee: Kao CorporationInventors: Koichi Hatano, Hiroyuki Yamashita, Masaaki Sakaue, Koji Toyoda, Yasuji Yamada

Patent number: 5766524Abstract: A method and apparatus for recovering concrete returned to the plant by delivery truck empties the delivery trucks into hoppers that dispense the so delivered left over concrete into molds designed to produce blocks of concrete suitable for regrinding into aggregate. The molded blocks are held in the molds for sufficient time to set the concrete for grinding before the blocks are separated from the molds. The molded blocks are then delivered to a grinding station where they are ground into aggregate of selected size for return to the concrete mixing operation. Any water that separates during the molding operation is subject to a settling operation to settle fine particles and the decanted water is then stored in a suitable reservoir for reuse, for example, in washing out the trucks.Type: GrantFiled: October 16, 1995Date of Patent: June 16, 1998Assignee: Governors of the University of AlbertaInventors: Mohammed M.
