Patents by Inventor Laurie Coyle

Laurie Coyle has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Pourable cast melt bar compositions comprising low levels of water and minimum ratios of polyol to water
    Patent number: 5916856
    Abstract: The present invention relates to cast melt bar composition comprising surfactant, fatty acid, generally lower MW polyalkylene glycol and small amounts of water wherein the ratio of total polyol to water is at least 3:1. By using less water and greater variants of polyol, the bars allow larger amounts of generally insoluble materials to be used and also allow retention of bar integrity using limited amounts of soap (important for mildness).
    Type: Grant
    Filed: October 16, 1996
    Date of Patent: June 29, 1999
    Assignee: Lever Brothers Company
    Inventors: Michael Massaro, Michael Fair, Sanghee Park, Laurie Coyle, Gail Beth Rattinger, Kevin Finucane
  • Process for accurately controlling moisture or solids levels of compositions with small amounts of or no surfactant
    Patent number: 5770251
    Abstract: The present invention relates to a process for preparing compositions or slurries containing edible surfactants (generally at low levels) or no surfactants at all using an NMR sensor designed to measure water or solids content of the composition on-line.
    Type: Grant
    Filed: August 20, 1997
    Date of Patent: June 23, 1998
    Assignee: Lever Brothers Company, Division of Conopco, Inc
    Inventors: Kevin Michael Finucane, Laurie Coyle
  • Apparatus for accurately controlling moisture levels of aqueous surfactant compositions during on line processing including a cross-feed piston assembly
    Patent number: 5594340
    Abstract: An apparatus for corring aqueous surfactant composition and sampling moisture content wherein the apparatus includes a device for delivering composition to a main collection port; a device for coring the composition in the main collection port to form a sample; a device for delivering the sample into an NMR sensor area; a device for measuring moisture level of the sample in the NMR sensor area; and a device for extracting the sample from the NMR sensor area or returning the sample to a main collection port which includes a cross feed piston assembly.
