40186350, Apr 19, 1977

Filed:

Mar 27, 1973

Appl. No.:

5/345375

Inventors:

Frederick M. Ryan - New Alexandria PA
Robert C. Miller - Pittsburgh PA

Assignee:

Westinghouse Electric Corporation - Pittsburgh PA

International Classification:

C06B 4500
C06B 4502
C06B 3900
C09K 300

US Classification:

149 2

Abstract:

Phosphor-explosive material combination and method wherein a small amount of inorganic phosphor is mixed with explosive material to provide an indicia or label of information regarding the explosive, either before or after detonation of same. The phosphor can readily be located with an ultraviolet lamp even after the explosive has been detonated, and by correlating the phosphor emission spectra with data known about the explosive when it is manufactured, the explosive can be identified. Line-emitting phosphors are especially useful because of their distinctive emision characteristics, which provide a vast number of possible combinations of emissions which are correlated against the data known about the explosive when it is manufactured. Preferably the phosphor is formed as a combination of finely divided "spotter" phosphor and finely divided "coding" material held together by a binder in the form of small conglomerates, in order to facilitate initial location and later identification of same. There exists a vast number of different combinations of distinctive fluorescent emissions, and these can be combined to label any item for later identification.

Filed:

Feb 11, 1992

Appl. No.:

7/833530

Inventors:

Frederick M. Ryan - New Alexandria PA
James W. Thomson - Murrysville PA

Assignee:

Rosemount Analytical Inc. - Eden Prairie MN

International Classification:

G01J 306
G01N 2131
G01N 2135

US Classification:

356308

Abstract:

An analyzer measures properties of multiple chemical samples, and includes an optical filter element having a long axis and positioned at a location where simultaneous multiple light beams, corresponding to the chemical samples to be measured, form a diffuse light spot elongated along an axis which is substantially aligned with the filter element long axis. The analyzer also includes a light source, filter means incorporating the filter element for transmitting spectrally selected portions of the light beams, sample cell means for exposing each sample to its associated light beam, and detector means for detecting the light beams after modification by the samples and after transmission by the filter. In a preferred embodiment, optical fibers carry the light beams to and from the chemical samples.

Abstract:

An inorganic fluorescent phosphor consisting of a spotting phosphor and a coding phosphor is employed for tagging purposes, as for example, tagging explosives to provide post detonation information. The spotting phosphor consists of an inorganic fluorescent material which is excited by UV to produce readily detectable band-type emission, but which produces little or no emission at certain excitation wave lengths. The coding phosphor consists of a different inorganic fluorescent material which emits a line-type emission and which fluoresces efficiently at those excitation wave lengths at which the spotting phosphor produces little or no emission. Exemplary spotting phosphors are zinc silicate and calcium silicate activated by manganese, which show no excitation at a UV radiation of 325 nm. Suitable coding phosphors are yttrium vanadate activated by trivalent rare earth ions, such as europium, thulium, erbium, dysprosium or Samarium. This combination of spotters and coding phosphors in cemented phosphor grains employed for tagging purposes enables the quantity of expensive coding phosphors required to be drastically reduced.
