Mar 7, 2008

Appl. No.:

12/044325

Inventors:

William G. Welch - Atlanta GA, US

Assignee:

ATLANTA SNAPSEAL LTD. - Marietta GA

International Classification:

B65D 51/20

US Classification:

2202572

Abstract:

A molded, tamper-evident seal for a liquid container is formed with a flat end wall, a cylindrical side wall having a flared edge, and three detents spaced by 120 degrees from one another and extending inward from the side wall. Score lines extend from the edge of the side wall, and past one of the detents on both sides thereof, toward the end wall. An outwardly protruding pull tab is located between the score lines adjacent the edge of the side wall.

US Classification:

514315

Abstract:

Appl. No.:

8/884414

Inventors:

William G. Welch - Atlanta GA

Assignee:

Atlanta Polyseal Ltd. - Marietta GA

International Classification:

B65D 5118

US Classification:

220257

Abstract:

A plastic bung seal forming two separate seals with the plug and collar of a receptacle. The bung seal allows ready detection of unauthorized access to the contents of the receptacle, since the double seal prevents its removal without visually perceptible destruction of the bung seal.

Appl. No.:

8/657481

William T. Welch - Ashland KY

Assignee:

Ashland Inc - Ashland KY

International Classification:

G01J 344
G01N 2165

US Classification:

356301

Abstract:

A distributed Bragg reflector (DBR) diode laser is used as excitation source for fiber optic Raman spectroscopy utilizing charge coupled device (CCD) detection and an image-corrected spectrograph. The DBR diode laser is superior to index guided diode lasers (Fabry-Perot) for elimination of mode hopping, elimination of frequency hysteresis as a function of both temperature and current changes, and reduction in laser broadband emission. These advantages allow the DBR laser to be used in industrial process control applications which are too demanding for index guided diode lasers.

International Classification:

G01N 2165

US Classification:

356301

Abstract:

Benzene and substituted aromatic hydrocarbons can be predicted within. +-. 31% vol or better, using Raman NIR spectroscopy and multivariate analysis, with optional fiberoptics multistreaming, preferably with Partial Least Squares regression analysis. The resulting signal can be used to control concentration of such compounds in product to desired levels.

International Classification:

G01N 2135

US Classification:

25033912

Abstract:

A Fourier-Transform Raman spectrometer was used to collect the Raman spectra of (208) commercial petroleum fuels. The individual motor and research octane numbers (MON and RON, respectively) were determined experimentally using the industry standard ASTM knock engine method. Partial Least Squares (PLS) regression analysis can be used to build regression models which correlate the Raman spectra (175) of the fuels with the experimentally determined values for MON, RON, and pump octane number (the average of MON and RON) of the fuels. Each of the models was validated using leave-one-out validation. The standard errors of validation (SEV) are 0. 415, 0. 535, and 0. 410 octane numbers for MON, RON, and pump octane number, respectively. By comparing the standard error of validation to the standard deviation for the experimentally determined octane numbers, it is evident that the accuracy of the Raman determined values is limited by the accuracy of the training set used in creating the models. The Raman regression models were used to predict the octane numbers for the fuels which were not used to build the models.
