US Classification:
419 65, 419 5, 419 23
Abstract:
The present invention is related to a family of materials that may act as a replacement for lead in applications where the high density of lead is important, but where the toxicity of lead is undesirable. The present invention more particularly provides a high density material comprising tungsten, fiber and binder. Methods and compositions of such materials and applications thereof are disclosed herein.

Abstract:
Corrosion, mold and moisture can be detected under outer layer of structures, such as surfaces associated with vessels and/or buildings, using nondestructive evaluation (NDE). Characterizing the dielectric properties of materials associated with a target can be executed by directing primary microwave energy from a source towards a target, receiving secondary microwave energy signals returned from the target, analyzing the secondary microwave energy signals, and characterizing dielectric properties of materials associated with the target based on analysis of the secondary signals. A system for non-destructively characterizing a target materials dielectric properties can includes a microwave energy source, a waveguide for directing microwave energy towards a target, a receiver for receiving microwave signals reflected off targets, an analyzer for assessing the difference between incident and reflected microwave signals to determine the presence of corrosion within a target or a targeted area, and an indicator for providing results of analysis.

International Classification:
F16B 1/00 F16B 19/04
US Classification:
411 823, 411 82
Abstract:
A fastener suitable for use in airplane manufacture or repair that is coated with a pre-mixed moisture cure sealant. The sealant layer is coated with a frangible moisture barrier that will break apart when the fastener is installed, thus exposing the sealant to atmospheric moisture. Once exposed to moisture, the sealant will begin to cure. Preferred embodiments also provide a moisture indicator that provides a visual indication that the outer moisture resistant layer has been damaged.

International Classification:
G01S 13/08
US Classification:
342104, 342105
Abstract:
A non-contact, distance traveled measurement system (DTMS) to calculate speed and distance traveled by a vehicle over rails—more specifically, by trains traveling on standard railroad tracks. Preferably, a pair of short range (near field) microwave-based transmitters/sensors (transceivers) are mounted on the underside of the train and used to key on rail-bed features such as cross ties or tie plates. Preferred embodiments also include infrared sensors as a redundant channel that is less sensitive to moisture in the track bed. Data from the sensors is correlated to determine the time delay between the first and second sensors' passage over objects on the rail bed such as cross-ties or tie-plates. From this time delay, nearly instantaneous velocity can be computed at each given target such as a tie plate (metal target) or a tie (dielectric contrast target). Velocity versus time curves can be integrated over time to derive distance traveled.

International Classification:
G01R 27/04 G01R 27/32
US Classification:
324644, 324642
Abstract:
An improved method and apparatus for non-destructive measurements of coating thicknesses on a curved surface by measuring components of the microwave energy reflected from the surface. Preferred embodiments of the present invention provide a portable microwave thickness detector with a rounded rocker-type base allowing the microwave beam to be moved through a range of angles with respect to the target surface. An optical alignment system determines when the microwave angle of incidence is at a desired angle when the components of the reflected microwave energy are measured. Preferred embodiments of the present invention also provide a portable microwave thickness detector which maintains a constant standoff distance between the between the microwave detector and the sample to be measured.
Modular Multi-Fiber/Conductor Connector And Insert

International Classification:
G02B006/38
US Classification:
385/055000
Abstract:
Underwater fiber optic connectors and methods of such connection are described wherein a first optical fiber and a first o-ring are positioned in a first connector portion. The first o-ring acts as a fulcrum between the first fiber and the first connector portion such that the first fiber is free to become nonparallel with a longitudinal axis of the first connector portion. The connectors and methods of connection can further comprise a second optical fiber and a second o-ring positioned within a second connector portion. Again, the second o-ring acts as a fulcrum between the second fiber and the second connector portion such that the second fiber is free to become nonparallel with a longitudinal axis of the second connector portion.
