US Patent:

20060078925, Apr 13, 2006

Filed:

Sep 22, 2005

Appl. No.:

11/232820

Inventors:

Zissimos Mourelatos - Philadelphia PA, US
Peter Nelson - Philadelphia PA, US

International Classification:

C12Q 1/68
C12P 19/34

US Classification:

435006000, 435091200

Abstract:

Provided are DNA microarray techniques that allow hybridization without RNA amplification, without using cDNA, and without labeling the nucleic acid prior to hybridization. Referred to as the Double-stranded Exonuclease Protection (DEP) assay, the technique permits the sample RNA to be used directly for hybridization, without manipulation in any way. Further provided is a microarray technique for high-throughput miRNA gene expression analyses, termed the RNA-primed, Array-based, Klenow Enzyme (RAKE) assay. The RAKE assay is a sensitive and specific technique for assessing single-stranded DNA and RNA targets, and offers specific advantages over Northern blots.

US Patent:

Filed:

Dec 7, 1981

Appl. No.:

6/328052

Inventors:

David J. Klee - Emmaus PA
Peter C. Nelson - Macungie PA

Assignee:

Air Products and Chemicals, Inc. - Allentown PA

International Classification:

F17C 702

US Classification:

62 51

Abstract:

The temperature actuated valve comprises a thermally more sensitive valve stem than the valve housing. The stem expands at a faster rate and causes vapor entering the valve to be gradually vented through an orifice of gradually increasing area as the temperature of the gas increases. It has application as a cryogenic phase separator valve which allows any cryogen vaporized in a cryogen delivery system to be automatically vented from the valve and to allow for an even flow of liquid to the spray nozzles and onto products of cryogenic freezing tunnels.

Appl. No.:

13/746303

Inventors:

Peter F. Nelson - Potomac MD, US

International Classification:

H02J 3/00

US Classification:

307 32

Abstract:

A multiple outlet sequenced power strip with only a specific number of outlets capable of running at any one time which is comprised of at least: a housing, input and output outlets, and a form of variable motor; thus allowing for the possible use of multiple high power devices on one wall socket and subsequently breaker.
