US Patent:

7517842, Apr 14, 2009

Filed:

Nov 10, 2006

Appl. No.:

11/595074

Inventors:

Ronald A. Barnhart - Clinton OH, US
David P. Lerner - Akron OH, US

Assignee:

GOJO Industries, Inc. - Akron OH

International Classification:

C11D 1/70
C11D 3/48
C11D 1/40

US Classification:

510138, 510130, 510131, 510382, 510386, 510388, 510499

Abstract:

An antimicrobial hand wash comprises an active ingredient and an amidoamine based cationic surfactant having a fatty chain with from 6 to 24 carbon atoms. These cationic surfactants are compatible with common active ingredients such that antimicrobial efficacy is maintained, while foam quality is improved when the hand wash is dispensed as foam. Other antimicrobial hand washes include specific amidoamine based cationic surfactants that dissolve at least a portion of the active ingredient, thus reducing the amount of solids in the formulation, and, in some instances, making a cold manufacturing process possible.

Appl. No.:

12/434355

Inventors:

Ronald A. Barnhart - Clinton OH, US
David P. Lerner - Akron OH, US

Assignee:

GOJO Industries, Inc. - Akron OH

International Classification:

A61K 7/00

US Classification:

510130, 510136, 510492, 510499

Abstract:

An antimicrobial hand wash includes a soap, an antimicrobial agent, and an amine salt. The amine salt is found to increase the antimicrobial efficacy of the hand wash. The amine salt produced through the reaction of monoethanolamine and lactic acid is of particular interest as a soap addition. In processes of this invention, it is possible to create the desired amine salt in the soap in situ.

International Classification:

A61K 8/00

US Classification:

510130, 510136, 510490, 510505

Abstract:

An antimicrobial hand wash comprises an active ingredient and an amphoteric surfactant that is a derivative compound of a fatty amine with a nitrogen atom bound to at least one, but not greater than two, propionic acids. These specific amphoteric surfactants have unexpectedly been found to be compatible with active ingredients such that the antimicrobial efficacy is maintained, while foam quality is improved when the hand wash is dispensed as foam. Other antimicrobial hand washes include polyethylene glycol or polypropylene glycol derivatives that dissolve at least a portion of the active ingredient, thus reducing the amount of solids in the formulation, and making a cold manufacturing process possible.

Filed:

Nov 4, 1975

Appl. No.:

5/628471

Inventors:

Gerald Lewis Freed - Highland Park NJ
David S. Lerner - Fanwood NJ

Assignee:

Lockheed Electronics Co., Inc. - Plainfield NJ

International Classification:

G08C 1938

US Classification:

340198

Abstract:

Circuitry monitors a plurality of rotating shafts, and provides a corresponding plurality of binary output words each characterizing the angular position of an associated shaft. Synchro and Scott "T" per-shaft monitoring elements are sampled by common multiplexer-central processor units which provide derived shaft position and shaft rate information to an appropriate one of plural shaft position output processors. In accordance with varying aspects of the present invention, the output processors include a rate multiplier controlled by the computer generated shaft rate signal, and a counter presetable by the CPU generated position signal, and advanced (decremented) by the rate multiplier output.

Inventors:

David R. Lerner - Mount Vernon NY

International Classification:

H02B 110

US Classification:

361377

Abstract:

An ultrahighlight fluorescent light mounting system for filming, particularly in color. A head carries the fluorescent tubes and a removable light shield while the ballast is positioned in a container remote from the head. The head is set upon and swivable about an upper post, which is rotatably connected to a lower post, which in turn is set upon and swivable about a swivel piece extending from a standard stand. The head, light shield, first post, second post, stand, and ballast can all be dissembled from one another and placed in carrying cases.
