Synthetic strapping made up of two layers of synthetic filament yarns with a bonding band formed of compatible synthetic material located between these layers and fusion bonded to the surfaces of the yarns with which the band is in contact, some of the band material extending into spaces between the yarns and into spaces between the filaments of the individual yarn.

A Synthetic Thorax for use with test dummies to simulate human bodily reactions under impact conditions. The Synthetic Thorax is made of high density polyethylene having dimensions similar to a human thorax and is 0.30 inch thick.

A synthetic suede product, which is produced from a plastic material, such as a vinyl plastisol, has the appearance and shading characteristics of natural suede leather. The product has about 10,000 to 500,000 untapered surface fibers per square inch, the diameters of which are a small fraction of their length.

Elimination of water from trimethylolpropane forms a mixture containing a substantial amount of di-trimethylolpropane. Esterification of the mixture with monobasic aliphatic carboxylic acids containing from about 2-12 carbon atoms such that the average acid chain is from 4-9 carbon atoms results in a synthetic ester lubricant especially useful for lubricating gas turbines.

7-(.alpha.-3-Acylureidophenylacetamido)- and 7-(.alpha.-3-acylureidothienylacetamido)cephalosporanic acids and the corresponding betaines and desacetoxy derivatives are valuable as antibacterial agents, as nutritional supplements in animal feeds and as therapeutic agents in poultry and animals, including man, and are especially useful in the treatment of infectious diseases caused by Gram-positive and Gram-negative bacteria, most particularly those caused by the Pseudomonas genus. 7-{D-.alpha.-[...

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 base oils for functional fluids and greases are provided comprising a mixture of monoalkylated naphthalenes and polyalkylated naphthalenes, said naphthalenes represented by the formula: ##STR1## wherein the R' groups are independently selected from H and methyl, the monoalkylated naphthalenes have three R groups which are H and one R group which is a 12-26 carbon alkyl, the polyalkylated naphthalenes have from two to four R groups which are 12-26 carbon alkyl and any remainder R groups...

A synthetic peptide growth hormone releasing factor having substantially the following amino acid sequence: ##STR1## methods of inducing growth in an animal and growth inducing pharmaceutical compositions, including animal feed compositions, are disclosed.

A synthetic replacement for down is described which comprises a blend of (a) 80 to 95 weight percent of synthetic, spun and drawn, crimped, staple, polyester microfibers having a diameter of from 3 to 12 microns; and (b) 5 to 20 weight percent of synthetic, thermoplastic, staple macrofibers having a diameter of from more than 12, up to 50 microns.

Synthetic sizes for use on yarns in water jet looms are prepared by copolymerizing methacrylic acid with from about 3% by weight to about 15% by weight of acrylic acid or vinylethoxytetraethylene glycol as the comonomer. These sizes are useful as nylon warp sizes in water jet looms. They have the desired adhesion to nylon and water resistance plus non-adhesion to steel parts on the loom.
