Apparatus for transmitting torque from the engine-driven crankshaft to the input shaft of the change-speed transmission in a motor vehicle has two coaxial flywheels which are rotatable relative to each other against the opposition of three series-connected dampers including a pair of annular slip clutches and an elastic damper between the slip clutches. One of the slip clutches opposes all angular...

A suspension system for linear reciprocating device which allows a relatively large axial stroke while also providing long life and high torsional and radial stiffness. The system consists of a grounded ring to which pairs of substantially coplanar cross straps are connected about an axis of symmetry around the ring. The midpoints of the straps are attached to the reciprocating device. In operatio...

A disposable, cloth-like towel of superior wet strength and absorbency comprises a scrim at least one face of which is coated with a superabsorbent material and a nonwoven cellulosic web which is bonded to the coated scrim. The superabsorbent coating preferably is formed by wetting the scrim with water or an aqueous adhesive, applying a solid hydrophilic polymer to the scrim, then applying a nonwo...

Silicon carbide fibers which are derived from oligomeric and/or polymeric precursors are modified and strengthened in annealing the silicon carbide fiber at temperatures in excess of 800 DEG C. under a nitrogen atmosphere in the presence of carbon particles. The modified fibers can be used to make ceramic, metal, and plastsic composites.

Means are disclosed to provide a ceramic article with a protective coating which resists mechanical wear at elevated temperatures up to 500 DEG C. and higher. The coating is applied by first chemically depositing activating metal ions on the uncoated ceramic surface and thereafter vapor depositing an adherent organic polymer lubrication film on the activated surface. Ceramic materials provided wi...

The invention is directed to isopsoralen compound compositions that contain a variety of substitutions which yet permit their binding to nucleic acid polymers. Reaction conditions that activate these bound isopsoralens results in covalent crosslinking to the nucleic acid polymers. The resultant complex is inhibited from being a template for the template-directed enzymatic synthesis of a complement...
