Patents by Inventor Ellen Bernice Brandes

Ellen Bernice Brandes 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).

  • Patent number: 8034754
    Abstract: The invention relates to lubricants which contain a phosphorus to nitrogen ratio of ?1.0 and a sulfur content of >1.4 wt. %. The phosphorus contribution is primarily from an acid phosphate species and the sulfur content is primarily from an antiwear agent. This lubricant composition has been found to provide exceptional protection to new gears or “green gears”, during the break-in phase.
    Type: Grant
    Filed: March 31, 2005
    Date of Patent: October 11, 2011
    Assignee: The Lubrizol Corporation
    Inventors: William T. Sullivan, Halou Oumar-Mahamat, Ellen Bernice Brandes
  • Patent number: 7902132
    Abstract: The invention relates to compositions suitable as additive packages for lubricants and other functional fluids, the composition comprising sulfur-containing extreme pressure components, phosphorus-containing anti-wear additives, a triazole-containing species. A preferred use is in industrial gear oils. In embodiments, enhance protection in the areas of bearing wear and micropitting are obtained.

  • Patent number: 7531486
    Abstract: The invention relates to additive systems which contain a phosphorus to nitrogen ratio of ?1.0. The phosphorus contribution is primarily from an acid phosphate species and the sulfur content is primarily from an antiwear agent. This lubricant composition has been found to provide exceptional protection to new gears or “green gears”, during the break-in phase.

  • Patent number: 5780540
    Abstract: The invention provides dispersants and dispersant viscosity index improvers which include polymers of conjugated dienes which have been hydrogenated and functionalized. The dispersant substances include compositions including a copolymer of two different conjugated dienes, a copolymer of a p-alkylstyrene and a conjugated diene, or a homopolymer of a conjugated diene. The polymers are selectively hydrogenated to produce polymers which have highly controlled amounts of unsaturation, permitting highly selective functionalization. Also provided are lubricant fluids, such as mineral and synthetic oils, which have been modified in their dispersancy and/or viscometric properties by means of the dispersant substances of the invention. Also provided are methods of modifying the dispersancy and/or viscometric properties of lubricating fluids such as mineral and synthetic lubricating oils. The dispersant substances may also include a carrier fluid to provide dispersant concentrates.
