Filed:

Feb 28, 2000

Appl. No.:

09/514668

Inventors:

Andrea K. Zimmerman - Wilmington DE
John A. Rodgers - Dayton TN
H. Ernest Romine - Ponca City OK
James R. McConaghy - Ponca City OK
Lorita Davis - Ponca City OK

Assignee:

ConocoPhillips Company - Houston TX

International Classification:

C10G 2700

US Classification:

208 6, 208 4, 208 39, 208 44, 4234476, 4234477

Abstract:

The present invention provides a process for thermosetting pitch fibers in reduced times, at low concentrations of oxygen and at higher temperatures than previously possible. Additionally, the present invention provides a pitch fiber which has an oxygen diffusion rate to the center of the fiber which is competitive with the rate of oxidation at the fibers surface. Further, the present invention provides a high density pitch fiber batt which thermosets without loss of fiber structure.

Filed:

Feb 23, 1976

Appl. No.:

5/660710

Inventors:

John Rodgers - Somerdale NJ

Assignee:

The Raymond Lee Organization, Inc. - New York NY

International Classification:

F24J 302

US Classification:

126270

Abstract:

A portable oven and grill heated by solar energy, which is fabricated of lightweight materials. The oven box is formed of a shaped open diagonal box, the walls of which are heat insulators, finished on their inner surfaces with a black matte surface to absorb radiated heat. Vanes formed of insulated panels coated on their upper sides with aluminum foil to reflect radiation are mounted along the top of each edge of the oven box and oriented at an obtuse angle to the vertical inner walls of the oven box. A glass panel is mounted across the open face of the oven box, which is inclined at an angle to horizontal bottom base wall of the oven, to retain the heat inside the oven compartment. A slidable metal grill plate is mounted to the inner bottom base wall so as to slide part ways out of the rear side of the oven wall while remaining in contact with an aluminum plate loosely mounted to the inner base bottom wall so as to be heated, for grilling purposes, when so extended out of the side wall.
