摘要:
A wire (10) for use in a brazing or soldering operation has an elongated body (12) of a metallic material. The elongated body (12) has an outer surface (18). A channel (14) is formed along a length of the body. The channel (14) has an opening (A1). A flux solution (22) is deposited within the channel (14) and along the length of the body. The flux solution (22) covers a portion of the outer surface (18). A portion of the flux solution (22) is exposed through the opening (A1) in the channel (14).

摘要:
The present invention is directed to a high surface area fiber and method for making the same. The fiber includes a co-extruded internal fiber and an external sheath that is washed with a solvent to remove the dissolvable external sheath, the resulting fiber having a longitudinal axis and a cross-section, the cross-section having a middle region and projections extending from the middle region.
摘要:
The present invention is directed to a high surface area fiber and textiles made from the same. In one preferred embodiment the fiber has a middle region with a plurality of projections that define a plurality of channels, which increases the surface area of the fiber. In one preferred embodiment, the fiber has a specific surface area of about 140,000 cm2/g or higher and a denier of about 1.0 to about 2.0. The fiber of the present invention is made using a bicomponent extrusion process using a thermoplastic polymer and a dissolvable sheath.
摘要:
A system for self-repairing matrices such as concrete or cementitous matrices, polymeric matrices, and/or fibrous matrices, including laminates thereof The system includes repair agents retained in and/or on vessels, such as hollow fibers, within the matrix. Upon impact, the vessel rupture, releasing the chemicals. For multi-layer laminates, the systems provides a total dynamic energetic circulation system that functions as an in situ fluidic system in at least one layer or area. The energy from the impact ruptures the vessels to release the chemical(s), and mixes the chemical(s) and pushes the chemical(s) and/or resulting compound through the matrix. The repair agents can withstand high temperatures, such as the heat of processing of many laminates, e.g., 250-350° F.

摘要:
Synthetic rocks are used as a substitute for natural gravel to fill in a water drainage trench. The synthetic rocks may be used around perforated drain tiles in a basement water drainage system, or they may be used without such tile. The synthetic rocks may be of a size and shape that mimics the natural rock they replace, but they are preferably significantly lighter in weight. The synthetic rocks may alternatively be tubular or cubic shaped, for example, and may include one or more lumens or other passageways to facilitate the flow of water through and/or around the rocks. The synthetic rocks may be provided in mesh bags to facilitate placement in a water drainage trench.

摘要:
The present invention is directed toward a substantially planar business communication assembly that has one or more ablated recesses or depressions which are created through the use of electromagnetic radiation. The assembly preferably includes first and second portions that are joined to one another to form a composite construction. The business form is typically provided with an ablated depression in one of the two portions. The depression has a depth that is sufficient such that when a removable element is placed within the depression the surface of the removable element is substantially planar with the surface of at least one of the surfaces of the portions used to make up the assembly.
