Patent number: 11584919Abstract: A capsule composition comprising: (a) a polyester shell having a thickness of no more than 20 microns, and (b) a solution containing a visual and/or olfactory indicator, wherein the solution is encapsulated by the polyester shell. Also described herein is a method for detecting alpha particle radiation, in which: (i) the capsule composition is placed in contact with an esterase in a location where the presence of alpha particle radiation is being determined; (ii) waiting a period of time for the esterase to degrade the polyester shells, wherein the period of time is insufficient for the esterase to cause leakage of the solution in the absence of alpha particle radiation but is sufficient for alpha particle radiation, if present, to cause leakage from the capsule composition; and (iii) observing whether leakage has occurred at the end of the period of time to determine whether alpha particle radiation is present.Type: GrantFiled: January 21, 2020Date of Patent: February 21, 2023Assignee: UT-Battelle, LLCInventors: Timothy E.

Patent number: 10571356Abstract: Provided is a Fluorescent Air Leakage Detection (FALD) system and method for locating a defect in an enclosure that uses a nontoxic fluorescent solution as a marker. The solution is aerosolized with an atomizing device and guided to defects by a gas pressure modifying device. Defects are visually located by surveying the enclosure with an ultraviolet or visible light source and identifying a location where accumulated solution fluoresces.Type: GrantFiled: September 13, 2017Date of Patent: February 25, 2020Assignee: UT-Battelle, LLCInventors: Diana E.

Patent number: 8689987Abstract: A container adapter for use in feeding human infants and animal infants is shown. The container adapter has an internal threaded portion that can comprise a set of thread segments sized and configured to match the external threads of a commercially available soda or bottled liquid container, and can have an external threaded portion sized to match the internal threads of a standard nipple ring for an infant feeding bottle. The container adapter includes a funnel that provides a user with assistance in inserting infant feeding ingredients into the liquid container by placing the container adapter on the liquid container to use the funnel of the container adapter to place infant feeding ingredients into the liquid container. The container adapter is then inverted and installed onto the liquid container. A nipple within a collar is attached to the container adapter thus converting the liquid container to an infant feeding bottle.Type: GrantFiled: May 27, 2011Date of Patent: April 8, 2014Inventor: Linda A.

Patent number: 5772055Abstract: The present invention provides a rotatable tower for holding and displaying books, video cassettes, and like articles on a plurality of square shelves which extend in horizontal planes and are supported in vertically spaced relation to one another by a plurality of vertically extending rods, groups of which are interconnected into L-shaped configurations by L-shaped, horizontally extending rods. The shelves include an elongated slot formed from the midpoint of each edge inwardly towards the shelves' geometric center, and two laterally spaced notches formed in each edge to one side of the slot. Each edge of the shelves includes a downwardly extending flange along their entire lengths and an upwardly extending flange along a portion of the length to the opposite side of the slot in which the notches are formed. Each L-shaped group of vertically extending rods is comprised of four rods, two rods forming each leg of the L.Type: GrantFiled: November 18, 1996Date of Patent: June 30, 1998Assignee: The Croydon Company, Inc.Inventors: Henry C.
