US Patent:

6563120, May 13, 2003

Filed:

Mar 6, 2002

Appl. No.:

10/091970

Inventors:

Charles E. Baldwin - Florence KY
Craig Caris - Crittenden KY

Assignee:

Ronan Engineering Co. - Woodland Hills CA

International Classification:

G01T 1203

US Classification:

250367, 250361 R, 2504831, 2504861, 2504881

Abstract:

Shown is a flexible scintillator, or scintillation-type level detector, in which the scintillator is made from a plurality of elongated, relatively thin layers of plastic scintillator material stacked in close proximity to one another in a slidable relationship to provide flexibility in at least two dimensions. The layers of at least one end are aligned for operable connection to a photodetector. Optionally, an anti-friction material, such as PTFE, may be placed between layers of the plastic scintillator material. Edge and outer face surfaces of the layers of the scintillator material may be covered with an inwardly facing light reflective material and/or light-excluding material.

Appl. No.:

10/810144

Inventors:

Charles E. Baldwin - Florence KY, US

Assignee:

Ronan Engineering Company - Florence KY

International Classification:

G01T 1/204

US Classification:

250361R, 2503571

Abstract:

A flexible scintillation-type level detector (), in which the scintillator () is made from a flexible tube () substantially filled with a liquid scintillating material () to provide flexibility in at least two, and preferably three, dimensions. At least one end () is aligned for operable connection to a photodetector (). Outer surfaces of the flexible tube () may be covered with an inwardly-facing light reflective material () and/or light-excluding material or flexible armored casing(). The scintillator () may include a variable-volume expansion chamber () to compensate for thermal expansion and contraction of the liquid scintillator material ().
