Abstract: A method of making high T.sub.c 1-2-3 superconductors having perovskite structure using solution techniques is disclosed. The process uses two solvent systems to form a resinous preceramic material having a controlled viscosity for facilitating its formation into superconducting articles such as fibers, wires, ribbons, films and the like. The process yields a pre-ceramic which is flexible and which has sufficient structural integrity to withstand normal handling.

Abstract: A method is provided for preparing piezoelectric fibers by concentrating a solution containing at least two metal alkoxides, a carboxylic acid and lead alkanoate to form a viscous liquid. The viscous liquid is drawn into amorphous fibers and the fibers are calcined and sintered to form the crystalline piezoelectric fibers.

Abstract: A dental floss holder and applicator of the type having an elongated handle and a pair of acutely angled tines projecting from one end of the handle incorporates a screw mechanism for securing the ends of a length of floss to the handle so that the length may be arrayed between the tines. The mechanism includes a screw which passes through a threaded hole at the base of the tines and has heads formed on its opposed ends to allow adjustment of position of the heads with respect to the base so that the ends of the length of floss may be captured between the heads and the base. A portion of the device is marked with color in contrast to the balance of the device to aid in identification of a specific device.

Abstract: Living cells suspensed in a saline buffering media are exposed to microwave radiation without raising the temperature of the cells, to study the non-thermal effects of radiation on the cells, in an apparatus which includes a vertically disposed microwave waveguide having a partitioned end filled with a temperature controlled liquid solution. The sample is contained in a micropipette which projects across the width of the waveguide through the solution. The radiation projected through the waveguide and into the solution is measured.
