John F. Dorrian 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).

  • Composition for cleaning hard surfaces
    Patent number: 6090765
    Abstract: The invention relates to an aqueous hard surface cleaner composition containing a synergistic combination of a surface tension reducing agent, a superwetting agent and an organic coupling/degreasing agent that targets each of the interfaces present when the cleaner is in contact with soil deposit on a hard surface to provide effective cleaning properties with a low concentration of active ingredients.
    Type: Grant
    Filed: December 10, 1998
    Date of Patent: July 18, 2000
    Assignee: Church & Dwight Co., Inc.
    Inventors: Robert H. Black, John F. Dorrian, J. Christopher Shannon
  • Process for applying conductive terminations to ceramic components
    Patent number: 4953273
    Abstract: In this process a conductive first layer composed of finely divided metal and finely divided ceramic material in an organic carrier is applied to a surface of an unsintered ceramic body. The conductive layer forms terminations when the body, and the conductive layer are cofired to sinter and form a unitary, integral, monolithic structure. A second conductive metal layer may be applied to the first layer prior to cofiring to improve attachment capabilities of the component. Leads may be attached to the conductive terminations if desired.

    Assignee: American Technical Ceramics Corporation
    Inventors: Victor D. Insetta, Richard V. Monsorno, John F. Dorrian
  • Base metal electrode capacitor and method of making the same
    Patent number: 4241378
    Abstract: A monolithic ceramic capacitor with base metal electrodes fired in an atmosphere of oxygen at low partial pressure in which the reaction between the electrodes and the ceramic prevents conversion of the ceramic into the semiconductive state. The base metal is a transition metal or a transition metal alloy, preferably nickel. The method is usable with any green ceramic without changing the firing temperature. The only change required is from the normal oxygen partial pressure in the kiln open to the atmosphere to an atmosphere of much lower oxygen partial pressure.
