Abstract: An in-situ method for monitoring the heath of a composite component (103) utilizes a condition sensor (101) made of electrically conductive particles (109) dispersed in a polymeric matrix (111). The sensor is bonded or otherwise formed on the matrix surface of the composite material. Age-related shrinkage of the sensor matrix results in a decrease in the resistivity of the condition sensor. Correlation of measured sensor resistivity with data from aged specimens allows indirect determination of mechanical properties and remaining age of the composite component.

Abstract: The present invention relates to lipid based nanoparticles or liposomes that are sensitive to ultrasonic energy, compositions containing these particles, methods for delivering one or more active agents using the particles, and methods for preparing the particles. The nanoparticles and liposomes encapsulate active agents such as chemotoxins, genes, virus vectors, proteins, peptides, antisense oligonucleotides, carbohydrates, and stem cells. The particles contain an aqueous core, at least one active agent located within the aqueous core, and a lipid bilayer or membrane that encapsulates the active agent within the aqueous core. The lipid bilayer may comprise a primary phospholipid and a lysolipid that preferably have different acyl chain lengths, making the lipid bilayer sensitive to ultrasound. Ultrasound may be used to track the particles as they move throughout the body. When the ultrasonic energy reaches a certain pressure, the lipid bilayer will break apart, releasing the active agent.

Abstract: An electrical condition monitoring method utilizes measurements of electrical resistivity of an age sensor (303) made of a conductive matrix or composite disposed in a polymeric structure such as an electrical cable (301). The conductive matrix comprises a base polymer and conductive filler. The method comprises a means for communicating the resistivity to a measuring instrument (317) as a means to correlate resistivity of the conductive matrix of the polymeric structure with resistivity of an accelerated-aged conductive composite.

Abstract: The present invention relates to a composition that includes gadolinium particles encapsulated in microsphere shells. The composition is suitable for use as a contrast agent with a plurality of imaging modalities, including, for example, ultrasound, magnetic resonance imaging, and computed temography. The compositions also are useful for therapeutic applications, including neutron capture therapy.

Abstract: A method for adhesively bonding opposed paperboard surfaces to each other to form a strengthened bond in a paperboard product and paperboard products formed thereof, comprising the steps of (A) applying a green-strength adhesive to at least a portion of the first paperboard surface; (B) applying a styrene-butadiene latex adhesive or a modified styrene-butadiene latex adhesive as a strengthening adhesive to at least a portion of either the first or the second paperboard surface such that the green-strength adhesive is substantially offset from the strengthening adhesive when the first and second paperboard surfaces are positioned in an opposed relationship; (C) orienting the first and second paperboard surfaces such that they are opposed to each other: and (D) contacting the first and second surfaces together to form the strengthened bond.

Abstract: Panel interlocking means for securing a pair of panels in overlapping face contacting relation includes a locking tab struck from one of the panels and arranged to be driven through a locking aperture defined by a retaining tab struck from the other panel and arranged so that its free end engages the locking tab in angularly disposed mutually bracing relation, holding means formed in said locking tab for receiving the free end of said retaining tab to hold said locking tab and said retaining tab in angular braced relation to each other, a securing tab projecting from a transverse edge of the locking aperture remote from the fold line of the retaining tab and disposed within a securing aperture struck from the locking tab and disposed at the base thereof and adjacent the locking tab fold line so as positively to secure the panels together against relative movement.

Abstract: Loaded article carriers of the basket style are tested by engaging the handle of the carrier with hanger means secured to a suitable gauge mounted on a ram which is driven upwardly by motive means in such manner as to cause the articles to engage a fixedly mounted stop plate and thereby to simulate a gradually increasing load on all critical parts of the carrier the magnitude of which is indicated by the gauge.
