Publication number: 20020074075Abstract: Reproducing, recoloring and/or recycling of used carpet tiles is provided. In accordance with one embodiment, used carpet tiles, which are recovered, are subjected to a choosing step according to the degree of stains, etc. The chosen carpet tiles are washed with a high-pressure fluid, and entangling of piles is removed and piles raised. The resultant carpet tiles are subjected to a choosing step once again according to the degree of stains, etc. The chosen carpet tiles are treated with such a design and color for recycling as to make less visible the stains or non-uniformity in color remaining after the washing, using a design computer, etc. Thus, reproduced carpet tiles are produced and subjected a choosing step once again, and the chosen ones are shipped.Type: ApplicationFiled: August 1, 2001Publication date: June 20, 2002Inventors: Robert S.

Patent number: 6019799Abstract: This invention relates to a method and apparatus for space-dyeing yarns. A yarn sheet passes over a yarn-driven roll equipped with a digital sensor that tracks the position of the sheet as it then passes through a dyeing apparatus. A computer precisely controls the spray application of dyes at the desired locations on the length of the yarn sheet. Undyed areas and areas of unwanted overlap of dyes are virtually eliminated, reducing the amount of off-quality yarn produced versus conventional methods. Sprayed dye droplets are collected and reused.Type: GrantFiled: March 6, 1998Date of Patent: February 1, 2000Inventors: Robert S. Brown, William M. Pascoe, Sr.

Patent number: 5984969Abstract: An augmentation system for an implantable bone prosthesis, such as a femoral component of a knee joint prosthesis, includes an augmenting block having an aperture disposed therein. A collet having an expandable distal end, extending beyond one surface of the augmenting block, is positioned within the aperture. The proximal end of the collet includes a cavity that receives an expansion pin that is adapted to communicate with the collet to expand the collet. The distal end of the collet is adapted to fit within a mounting cavity of a joint prosthesis. With the augmenting block placed on the appropriate surface of the joint prosthesis, the distal end of the collet is positioned within the mounting cavity. Advancement of the expansion pin causes the distal end of the collet to expand, thus frictionally and/or mechanically engaging the interior walls of the mounting cavity to firmly secure the augmenting system to the prosthesis.Type: GrantFiled: November 28, 1995Date of Patent: November 16, 1999Assignee: Johnson & Johnson Professional, Inc.Inventors: Frank D. Matthews, Robert S. Brown, Gerald J. Cicierega, Robert Hurlburt, Michael J. O'Neil

Patent number: 5017437Abstract: A process for making a clad article of a densified metal powder core and a compatible metal cladding metallurgically bonded thereto results in a significantly reduced concentration of metal oxides in the core so as to prevent embrittlement of the core at and adjacent the core/cladding interface that results in rupture between the core and the cladding along the interface during working or forming. In carrying out the process, the temperature of the undensified metal powder and/or the temperature of the compatible metal container into which the metal powder is filled are closely controlled so as to avoid adsorption of moisture during the filling step.Type: GrantFiled: July 20, 1990Date of Patent: May 21, 1991Assignee: Carpenter Technology CorporationInventors: James W. Martin, Robert S. Brown, E. Lance Buck, Gregory J. Del Corso

Patent number: 4765134Abstract: The periodic shedding of vortices produced in a highly sheared gas flow, such as that encountered at the grain transition boundary in a solid propellant rocket motor or at the combustor inlet to a ramjet engine, is a significant source of acoustic instability which may result in unstarting of the ramjet engine or excessive vibration of the rocket motor. By restricting the transition boundary or combustor inlet at the sudden expansion dump plane (5), such as by locating an orifice plate (13) at the dump plane, the gas flow is separated upstream and produces a vena contracta downstream of the orifice, inhibiting the feedback of acoustic pressure to the point of flow separation and preventing the formation of organized oscillations. Incorporation of such a simple thin plate orifice at the dump plane reduces the periodic acoustic oscillations and thereby controls the detrimental oscillatory pressure fluctuations.Type: GrantFiled: August 28, 1986Date of Patent: August 23, 1988Assignee: United Technologies CorporationInventors: Robert S. Brown, Roger Dunlap
