摘要:
A composite structural material and a method of making it, which material is thermoformable and capable of being rigidified by application of a resin, and which is useful in certain electronics applications because of a metallic layer incorporated within the structure. A layer of a selected metal is needle punched onto a fibrous batt of selected synthetic thermoplastic fibers, which is then thermoformed to a desired shape and rigidified by contacting with, and being embedded in, a suitable resin. Specific applications of the use of this composite include a parabolic dish-shaped antenna, an electromagnetic interference shield for electronic equipment, and a radioactive emission shield.

A nonwoven textile fiber panel, useful, for instance, in manufacturing car truck liners, in which synthetic thermoplastic fibers that vary in fiber length, diameter, denier, and/or density are needle-punched to produce a carpeting material, which can then be directly utilized, or thermoformed to retain a desired shape. The fibers that one desires to show up on the face side of the final product are preferentially driven by the needle barbs of a needle loom through the precursor batt material. This preferential needling can also be enhanced through selection of various needle lengths, needle diameters, and barb spacing configurations.

The adverse effects of various sources of error present in satellite imaging when determining ground location information are reduced to provide more accurate ground location information for imagery, thereby rendering the information more useful for various entities utilizing the images. The determination of ground location coordinates associated with one or more pixels of an image acquired by an imaging system aboard a satellite or other remote platform includes obtaining a first earth image associated with a first earth view, obtaining a second earth image associated with a second earth view, the second earth image not overlapping the first earth image, and using known location information associated with the first earth image to determine location information associated with the second earth image.

During a visit to the Grand Canyon, my wife and I wanted to purchase a small sculpture of what the Paiutes call Kaibab, or “Mountain Lying Down.” Not finding one available, I was inspired to create this evocative piece of memorabilia for all those who come to experience one of the seven natural wonders of the world.

A meter for determining the integrated effect of the exposure of human skin to the sun's ultra-violet radiation by means that provide an instrument cheap enough to use on a wide scale. The World Health Organization sees "the greatest value" in a suitable instrument. The solar radiation is passed through a UV filter to a fused silica tube containing a disulphide solution which, under the action of ultra violet (UV) radiation, displays a wavelength response similar to that of the erythemal action spectrum.

A filtering system provides an oil flow to a filter carried by a support offset from a down tube of a motorcycle frame. An engine mounted bracket directs oil flow to be filtered to a cap assembly which is attached to an oil conduit. A threaded tubular member of the cap assembly permits rotational positioning of the attached conduit end, and positioning of the conduit, to facilitate conduit passage past motorcycle components to the filter support.

A gas permeable, self-supporting, molded textile duct which matches the surrounding area in color and texture is disclosed which is useful to convey heated or conditioned air. The ducting is particularly useful for the interior of recreational vehicles. The ducting is prepared by thermomolding techniques.
摘要:
A resilient, low modulus, semirigid shell for use as a component of an article of luggage. The shell comprises a first nonwoven batt of thermoplastic resin fibers and an exterior material attached to the first nonwoven batt. The first batt and exterior material are thermally formed to a predetermined shape. The shell may also include one or more additional component layers selected from a second nonwoven, fibrous batt, a layer of backing material, a water impermeable film, and a lining material. In manufacturing the shell, the exterior material is attached to a first portion of a substrate material which is comprised of the nonwoven batt of thermoplastic resin fibers. A second portion of the substrate material is secured to an apparatus for thermal forming and the exterior material and substrate material are thermally formed to a resilient, low modulus, semirigid shell having a predetermined configuration.
