Patents by Inventor Paschal A. Sciarra

Paschal A. Sciarra 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: 6916574
    Abstract: A method for forming an electrode for a fuel cell is disclosed. The method comprises combining an electrically conductive material (e.g., graphite) and a solid grindable resole resin binder, the binder being essentially free of nitrogen and nitrogen-containing compounds, and consolidating the electrically conductive material and the binder to form the fuel cell electrode. The use of a solid, grindable, single stage, nitrogen-free resole resin binder serves to increase the operating life of the electrode. One example binder comprises the reaction product of bisphenol A and a molar excess of an aldehyde, such as formaldehyde.
    Type: Grant
    Filed: July 9, 2003
    Date of Patent: July 12, 2005
    Assignee: Plastics Engineering Company

  • Patent number: 5714525
    Abstract: Densified particles of friction ingredients which include an uncured mix of friction ingredients with a thermosetting binder resin and an effective amount of a liquid coreactive with the resin which maintains the temperature during particle formation below the curing temperature of the resin can be used to make friction elements. Methods of forming friction elements from the particles and friction elements made from the particles also are described.

  • Patent number: 5360587
    Abstract: A method for preparing a friction element from rod-like particles of friction ingredients includes preheating the particles, which have a diameter of about 3/32" to about 1/4", to a temperature between 150.degree. F. and 375.degree. F., introducing a predetermined amount of the preheated rod-like particles into a friction element mold, and compressing the preheated rod-like particles under heat and pressure to form the friction element. Compositions for forming the rod-like particles are disclosed.
