Piling, coated surface

The most usual forms of buried metal structures are pipelines, piles, tanks and power and telephone cables. Power cables must usually have some metal protection, covered by expensive continuous factory-applied sheathings of considerable thickness. Since water, gas and petroleum pipelines provide the greatest area of metal surfaces to be protected below ground, a detailed discussion of the protection given to them would appear to be the best means of dealing with coatings for underground use. 

Another application concerning the liquid-metal-cooled fast breeder reactors (LMFBR) was studied as development of advanced control rod materials for FBR (22). Fabrication tests and out-of-pile measurements were made of B4C/Cu cermet to obtain high-performance neutron absorber materials for LMFBR. A coating layer of Cu was formed on the surface of B4C/Cu powder, and then the coated B4C... 

By piling up several honeycombs, a wide-band multilayered architecture can be fabricated. Besides, by coating this structure with an epoxy resin, the thermal stability is enhanced and the surface impedance can be modified [106],... 

Chinchilla cloth n. A heavy, twill weave, filling-pile fabric with a napped surface that is rolled into little tufts or nubs. The material is frequently double faced with a knitted or woven, plain or fancy back. Chinchilla cloth is used primarily in coats. The term is also used to refer to a knitted woolen fabric having a napped surface. 

Another insect that can cause extensive damage is the wood-boring beetle. Small surface holes and piles of sawdust are indications of the presence of this insect. Thorough surface coatings of paint or varnish are the best control measures. 

However, in multicell pile configuration reserve batteries, there is a considerable chance for intercell short-circuiting in the common electrolyte manifold. This intercell shortcircuiting not only dissipates the capacity of the cells, but it can also allow for dendritic growth, which can lead to electronic short-circuiting of the cells with catastrophic results. Experience has shown that such dendritic growth can be minimized or eliminated if all interior metallic surfaces of the battery have a nonconductive (usually Teflon-based) coating. 

Metallic Fiber n A manufactured fiber composed of metal, plastic-coated metal, metal coated plastic, or a core completely covered by metal (FTC definition). They are available in yam form as well as in staple form for spinning with other fibers. A core yarn with a metal surface is produced by twisting a strip of metal around yarn of natural or manufactured fibers. The most important characteristic of metallic fiber and the chief reason for its use in textiles is glitter. Metallic fibers are used as a decorative accent in fabrics for apparel, bedspreads, towels, draperies, and upholstery. A relatively new application for metallic fibers is in carpet pile, where they are being used in small percentages for control of static electricity.
