Appl. No.:

12/135154

Inventors:

Susan C. Chang - Canonsburg PA, US
Douglas J. Merriman - Wheeling WV, US
Jesse M. Blacker - Bridgeport OH, US
Rick D. Lucas - St. Clairsville OH, US

Assignee:

Touchstone Research Laboratory, Ltd. - Triadelphia WV

International Classification:

B32B 3/26
B32B 3/00
B32B 9/00

US Classification:

4283044, 4283166, 4283184

Abstract:

A blast energy mitigating composite useful for protecting a surface or an object from a blast, shock waves, or stress waves caused by a sudden, violent release of energy is described. Certain configurations of the blast energy mitigating composite may include energy mitigating units contained in an energy mitigating matrix. If desired, various reinforcement layers may be incorporated on or within the energy mitigating composite. The energy mitigating units may comprise a porous energy mitigating material such as carbon foam.

Appl. No.:

11/331416

Inventors:

Susan Chang - Canonsburg PA, US
Brian Joseph - Wheeling WV, US
Rick Lucas - St.Clairsville OH, US

International Classification:

B32B 18/00
B32B 3/26

US Classification:

428304400, 428293400

Abstract:

A selectively reinforced carbon foam body is described. The carbon foam body includes one or more reinforcement regions in predetermined locations within the carbon foam body. The reinforcement regions may be formed by permeating portions of the carbon foam body with a precursor to a reinforcement material in a predetermined pattern to form one or more reinforcement regions. The reinforcement regions may have differing sizes and shapes. The selective reinforcement of a carbon foam body allows for additional strength to be provided in needed areas while still maintaining the low density attributes of carbon foam.

Filed:

Nov 9, 2010

Appl. No.:

12/927162

Inventors:

Susan C. Chang - Pittsburgh PA, US

Assignee:

Technical Analysis & Services International, Inc. (TASI) - McMurray PA

International Classification:

F24H 1/10

US Classification:

392465

Abstract:

An active air heater is constructed to produce heat and to transfer heat to an air flow for heating a building. The active air heater comprises spaced apart fins; adjacent elements between the fins; and an electrical source directing an electrical current through the fins and the adjacent elements for heating the fins and the adjacent elements and the air flowing through the air flow passageways formed by the adjacent elements. The adjacent elements are porous, semi-conductor material having a roughness in its surfaces for enhancing the convective heat transfer between the material and the air flow. The active air heater may be rectangular or cylindrical. The porous, semi-conductor material includes carbon foams, ceramic foams, high temperature polymer foams, and low conductance alloy foams and the aforementioned materials in nano-material format.
