Patent number: 7082019Abstract: Methods and apparatuses are disclosed for protecting solar cells from cellular degradation caused by an electrostatic discharge pulse. In one embodiment, a diode may bypass current generated from an electrostatic discharge so that the pulse current does not reverse bias the solar cell. Advanced diodes, capacitors and/or multiple diodes located on multiple bypass current paths, may be used. In another embodiment, the transient impedance of the current path that reverse biases the solar cell is increased by using inductors placed along the reversing current path. In another embodiment, the pulse current rise rate is reduced by extending the harness length of cell contacts. In another embodiment, solar cells in a serpentine pattern may be protected from electrostatic discharge damage by coupling bypass current paths to the open ends of the serpentine. Inductors may also be placed in series with the serpentine series of cells.Type: GrantFiled: November 4, 2002Date of Patent: July 25, 2006Assignee: The Boeing CompanyInventors: John Michael Bodeau, Philip L.

Patent number: 6008408Abstract: The present invention relates to a process for the hydroxycarbonylation of pentenoic acids. By the process, one or a number of pentenoic acids are hydroxycarbonylated to adipic acid, by carbon monoxide and water, in the presence of a catalyst based on iridium and/or rhodium and of at least one iodinated promoter. The reaction mixture obtained is subjected to a refining operation, after having optionally been concentrated, making it possible to separate at least a part of the catalyst. The catalyst thus separated is recycled to an operation for the hydroxycarbonylation of pentenoic acids, of butadiene, or of butadiene derivatives.Type: GrantFiled: July 11, 1995Date of Patent: December 28, 1999Assignee: Rhone-Poulenc ChimieInventors: Philippe Denis, Francois Klinger, Jean-Claude Laurent, Robert Perron, Joel Schwartz, Francois Vachet

Patent number: 5973197Abstract: A method for preparing carboxylic acids by carbonylating a reagent, particularly an alcohol, in the presence of a rhodium catalyst. According to the method, the liquid phase reaction is carried out in a first zone in the presence of a rhodium catalyst, and the resulting reaction mixture is partially vaporised in a second zone. The vaporised fraction containing the carboxylic acid is later purified and the unvaporised liquid fraction containing the catalyst is recirculated to the first zone. The method is charactracterised in that said unvaporised fraction is contacted with carbon monoxide in such a way that this compound is not returned to the second zone.Type: GrantFiled: April 21, 1997Date of Patent: October 26, 1999Assignee: BP Chemicals LimitedInventors: Philippe Denis, Robert Perron, Joel Schwartz
