Abstract: A wrist rest assembly has a base with a first end, a second end, and a pivot post mounted on the base near the first end. A tray has an elongated slot that receives the pivot post to allow movement of the tray about the pivot post.

Abstract: The crystallinity of an amorphous precursor polycarbonate is enhanced by contact in the liquid or vapor state with a non-solvent which may be water, an alkanol or a mixture thereof and which is dialkyl carbonate-free. Contact temperatures are at least about 75.degree. C. and are further defined by the relationshipT.sub.c .gtoreq.T.sub.b -z,wherein T.sub.c is the contact temperature, T.sub.b is the boiling point of the non-solvent at the contact pressure employed (both in degrees C.) and z is a constant whose value is 60.

Abstract: The invention relates to polycarbonates suitable for use in optical articles; the polycarbonates contain residues of alicyclic bisphenols and have properties particularly suited for use in high density optical data storage media. The polycarbonates further contain residues of other monomers, such as SBI and its derivatives; bisphenols, such as bisphenol A; CD-1 and its derivatives or some combination of each.

Abstract: A method of forming a thin film of a metal oxide on a substrate by coating the substrate with a solution comprising metal-organic precursors is disclosed. This method is applicable to, e.g., forming thin films of perovskite-phase titanates, zirconates, and/or niobates of divalent metals such as Ba, Sr, Pb and/or Ca. In one embodiment, a first precursor comprises a divalent metal coordinated to one or more organic ligands, and a second precursor comprises a tetravalent metal coordinated to one or more organic ligands are supplied in a common solution. A substrate 14 is coated with this solution (e.g. by spin coating) to form a preliminary thin film 10. Substrate heater 22 preferably heats substrate 14 to a temperature sufficient to react ligands from the first and second precursors in an ester elimination reaction which forms a volatile precursor 16. This reaction leaves an intermediate compound film 12 comprising the divalent metal and the tetravalent metal on the substrate.

Abstract: A method of systemically controlling endoparasites and ectoparasites of warm-blooded animals by orally or percutaneously administering to the animal a parasiticidally effective amount of an acyl urea compound.

Abstract: Polyimides, especially thermoset polyimides such as those prepared by the reaction of p-phenylenediamine with 4,4'-hexafluoroisopropylidenebis(phthalic anhydride) and nadic ester, are converted to monomers which may be recycled for polyimide synthesis by heating with a solution of an alkali metal hydroxide, such as lithium hydroxide or sodium hydroxide, in a dipolar aprotic solvent such as N-methylpyrrolidone. The products are the diamine and the tetracarboxylic acid alkali metal salt corresponding to the dianhydride.
