A synthetic suede is disclosed comprising a flexible backing having a multiplicity of upstanding flock fibers adhered to the base, and a fatty acid radical cationic softener substantially uniformly distributed over at least portions of the fibers at or near their ends. Typical cationic softeners include the fatty acid quaternary ammonium softeners.

The application discloses novel synthetic compounds, modeled after unique toxins extracted from the marine invertebrate Diazona angulata useful in the treatment abnormal cell mitosis. The application also discloses novel methods for synthesis of these compounds and methods of using these compounds.

An artificial (namely synthetic) bone material is made up of a strength sustaining first component and of a biointegration promoting second component. The first component is made, for example of a bioceramic material providing a material strength, especially a compression strength, of at least 1000 N/cm.sup.2. The second component is made also of bioceramic material or even of bone tissue or it may contain bone tissue in combination with other biointegration enhancing components. Biointegration ...

A synthetic resin contains, as essential components, A) a crosslinkable binder selected from the group consisting of the polymers, polyadducts or polycondensates having reactive centers in the form of hydroxyl, thio or primary or secondary amino groups and B) a crosslinking agent based on at least one polyoxyalkylene polyisocyanate and C) a crosslinking agent which differs from (B) and is based on .gamma..sub.1) a polyfunctional isocyanate which differs from (B) or .gamma..sub.2) an organic comp...

Synthetic tRNAs are produced from tRNA.sup.Cys (AAA), tRNA.sup.Ser (AAA), tRNA.sub.e.sup.Ala (AAA), and tRNA.sub.i.sup.Ala (AAA) genes. Polyuridylic acid-dependent syntheses of polypeptides were carried out in vitro on E. coli ribosomes using the synthetic tRNAs.

This invention pertains to a synthetic adhesive composition for use in aqueous environments. The composition comprises polypeptide chains having an .alpha.-helical structure in aqueous environments and capable of cohesive and adhesive interactions. The polypeptide chains comprise polar and apolar amino acids, the apolar and polar amino acids being arranged to define apolar and polar vertical spiraling stripes on the helix surface. The apolar stripes allow the polypeptide chains to aggregate into...

Synthetic resins are based on products which are obtainable by reacting A) epoxy-carrying resins based on a.sub.1) polyhydric phenols and a.sub.2) at least one compound selected from the group consisting of .alpha..sub.1) polyoxyalkylenepolyols, .alpha..sub.2) polyoxyalkylenepolyepoxides, .alpha..sub.3) polyoxyalkylenepolyamines and .alpha..sub.4) polyhydric aliphatic alcohols and, if desired, a.sub.3) phenolic compounds which react monofunctionally toward epoxides, B) monocarboxylic acids of 5 ...

A synthetic crosstie for railway track having integral canted rail-supporting portions and also having cross-sectional shapes adapted to adequately embed themselves into the ballast while taking into account minimum interference with ballast-tamping apparatus.

This invention relates to synthetic fiber thermal insulator material in the form of a cohesive fiber structure, which structure comprises an assemblage of: (a) from 70 to 95 weight percent of synthetic polymeric microfibers having a diameter of from 3 to 12 microns; and (b) from 5 to 30 weight percent of synthetic polymeric macrofibers having a diameter of 12 to 50 microns, characterized in that at least some of the fibers are bonded at their contact points, the bonding being such that the densi...

Synthetic and metal are reclaimed from a synthetic-metal scrap combination by first comminuting the scrap particles in which metal and synthetic are not yet separated; grinding and pulverizing these particles to obtain a fluidized blend of synthetic fibers and metal spheres; and providing an air flow carrying the fibers and balls in a blend so as to obtain subsequent separation from each other.
