Filed:

Apr 25, 2008

Appl. No.:

12/150163

Inventors:

Richard S. Simons - Akron OH, US

Assignee:

Maverick Corporation - Blue Ash OH

International Classification:

H01B 1/06

US Classification:

252506, 210688, 524847, 525416

Abstract:

Metal complexes (“compatibilizers”) having properties particularly useful for treating and compatibilizing nanomaterials (i. e. carbon nanotubes, nanofibers, nanographite) include metal cations and anionic surfactants. The treated nanomaterials can be isolated as solid treated nanomaterial and used in further applications where increased dispersion is desirable.

Appl. No.:

8/099667

Honeywell Inc. - Minneapolis MN

International Classification:

F23N 500

US Classification:

431 6

Abstract:

A flame rectification type flame sensor circuit and method in which a generator injects periodic pulses of alternating voltage into a flame region, the voltage across the flame region being processed by a filter/amplifier which, in proper operation, produces a non-zero output signal only during the time a flame is present and a pulse of alternating voltage is being supplied by the generator. Final indication of a flame is produced only if a non-zero output signal occurs during the time a pulse of alternating voltage is being supplied, and not during the time between successive pulses of alternating voltage. Failure of an electrical component in the filter/amplifier is indicated if a non-zero output signal occurs during the time between successive pulses of alternating voltage.
