Patents by Inventor Reuben H. Bell

Reuben H. Bell 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).

  • Molding compounds
    Patent number: 4036806
    Abstract: We have developed molding compounds from cement in combination with a nylon or polyester resin. We form the resin in the presence of the cement. We can use these molding compounds to form molded articles which have good fire resistance.
    Type: Grant
    Filed: October 8, 1975
    Date of Patent: July 19, 1977
    Assignee: Owens-Corning Fiberglas Corporation
    Inventors: Kevin M. Foley, Reuben H. Bell, Frank P. McCombs
  • Aniline based reaction product
    Patent number: 4001329
    Abstract: A reaction product between propoxylated aniline, formaldehyde and diethanol amine is disclosed. In another embodiment, aromatic compounds can be reacted with the propoxylated aniline in addition to the formaldehyde and diethanol amine. The resulting product can be reacted with an alkylene oxide to produce a polyol which can be employed in the production of polyurethane foams.

  • Fire resistant epoxy resins cured with phosphorus trihalides
    Patent number: 3971750
    Abstract: We have developed new and useful epoxy resins which have excellent fire resistance. We prepare these resins by using phosphorus trihalides or phosphorus oxyhalides to cure conventional epoxy resins.

  • Molding compounds
    Patent number: 3944515
    Abstract: A method for producing a phenolic molding is disclosed. The method includes the steps of mixing phenol, formaldehyde and a hydraulic cement, forming the resulting composition to a predetermined shape and maintaining the composition in the predetermined shape until an insoluble, infusible article is formed by condensation. At least 10 percent of the hydraulic cement must be Portland cement. The mole ratio of formaldehyde to phenol must be at least 1:1, and the amount of hydraulic cement must be sufficient for reaction with from 1 to 9 times the sum of the water of condensation of the phenol with the formaldehyde and the water charged to the mix. The use of reinforcing glass fibers in producing phenolic moldings is also disclosed, as well as the use of urea and resorcinol in addition to the phenol, formaldehyde and hydraulic cement.

  • Flame retardants for plastic foams
    Patent number: 3943076
    Abstract: Addition products of polyepoxides which have proved to be excellent flame-retardants for plastic foams such as polyurethane foams are disclosed.
    Type: Grant
    Filed: January 27, 1975
    Date of Patent: March 9, 1976
    Assignee: Owens-Corning Fiberglas Corporation
    Inventors: Reuben H. Bell, Kevin M. Foley
  • Fire retardant polyurethane foams
    Patent number: 3943077
    Abstract: Flame retardant polyurethane foams are disclosed. Flame resistance is achieved by a combination of at least three polyols. Control of internal exotherm is achieved by the addition to the foams of an inorganic material such as hydrated alumina.
