John F. Terbot 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).

  • Siliceous oxide comprising an alkaline constituent
    Patent number: 5858909
    Abstract: Siliceous oxides having a combination of low total volatiles content and basic pH are useful as odor control agents in organic resin systems, especially polyolefin-based systems. These modified siliceous oxides advantageously reduce odor and off-trade while minimizing discoloration of the resin. The adsorbents are especially useful for resin systems containing fatty acid amide slip aids.
    Type: Grant
    Filed: September 27, 1996
    Date of Patent: January 12, 1999
    Assignee: W. R. Grace & Co.-Conn.
    Inventors: William A. Welsh, John F. Terbot
  • Catalytic cracking utilizing a zeolite and aluminum phosphate-containing catalyst
    Patent number: 5286369
    Abstract: Catalyst compositions are described which comprise crystalline molecular sieve zeolites and an aluminum phosphate component having a surface area of less than about 50 m.sup.2 /g and a high degree of attrition resistance. The catalysts are particularly effective for the catalytic cracking of high molecular hydrocarbon feedstocks to obtain enhanced yields of C.sub.3 and C.sub.4 olefins such as isobutylene.

  • Low sintering cordierite powder composition
    Patent number: 5173455
    Abstract: A Group IIA metal-Group IIIA metal-silicon substantially homogeneous liquid alkoxide is prepared from a reaction mixture of a Group IIA metal, a Group IIIA metal, a silicon tetraalkoxide, and a liquid defined by the formula ROR' where R is an alkyl group and R' is hydrogen or an alkyl group. The alkoxide can then be hydrolyzed, azeotropically distilled, dried, milled, and calcined to produce a ceramic powder. Advantageously, the ceramic powder can be compacted and sintered at relatively low temperatures which enable it to be used in electrical applications where high sintering temperatures would be deleterious.
