Abstract: A sensor element is provided including a polymer exhibiting a measurable property from the group of luminescence and electrical conductivity, the polymer being complexed with a unit including a recognition element, a tethering element and a property-altering element bound thereto so as to alter the measurable property, the unit being susceptible of subsequent separation from the polymer upon exposure to an agent having an affinity for binding to the recognition element whereupon the separation of the unit from the polymer results in a detectable change in the measurable property.

A newly recognized class of ligands for making copolymer containing polar monomers using late transition metal complexes is described.

Abstract: A joint has a first leaf having an inner gear and a second leaf having an external gear meshing with the inner gear. A driving wedge-shaped disk is non-rotatably attached to a shaft and rotatably received between the leaves. A block with an outer wedge-shaped resistant surface is formed on the driving wedge-shaped disk. At least one driven wedge-shaped segment is mounted around the driving wedge-shaped disk. Each segment has an inner wedge-shaped surface to mate with the outer wedge-shaped resistant surface of block. A wedge arrangement is arranged between a supporting base on the disk and each segment to raise the segment as the driving wedge-shaped disk is rotated with the shaft. Accordingly, the angle between the first leaf and the second leaf can be adjusted. In addition, the shaking of the second leaf with respect to the first leaf can be prevented.

A cover is pivotally connected to the base and a notch is defined in a side of the cover. A retaining member has a passage defined in an intermediate portion thereof so as to receive the rod therein. A spring is biased between a first end of the retaining member and the base. A second end of the retaining member has a hook which is disengagably engaged with the notch. The cover can be pivoted away from the base by releasing the hook from the notch so that the cover will not loose.

Abstract: A joint has a first leaf having an inner gear and a second leaf having an external gear meshing with the inner gear. A stub with a wedge-shaped outer periphery is formed on the first leaf. A driving member is non-rotatably attached to a shaft and rotatably received between the leaves. A supporting base is mounted between the leaves and is actuated by the driving member. At least one driven wedge-shaped segment is mounted around the stub. Each segment has an inner wedge-shaped surface to mate with the outer wedge-shaped outer periphery of stub. A wedge arrangement is arranged between the supporting base and each segment to raise the segment as the driving member is rotated with the shaft. Accordingly, the angle between the leaves can be adjusted, and the shaking of the second leaf with respect to the first leaf can be prevented.

Abstract: Optical limiting device and method of preparation thereof. The optical limiting device includes a transparent substrate and at least one homogeneous layer of an RSA material in polyvinylbutyral attached to the substrate. The device may be produced by preparing a solution of an RSA material, preferably a metallophthalocyanine complex, and a solution of polyvinylbutyral, and then mixing the two solutions together to remove air bubbles. The resulting solution is layered onto the substrate and the solvent is evaporated. The method can be used to produce a dual tandem optical limiting device.

Abstract: The template-guided synthesis of water-soluble, chiral conducting polymer complexes is described. Synthesis of water-soluble polyaniline complexes is achieved by carefully controlling the experimental parameters such as; acid concentration, ionic strength, monomer/template ratio, total reagent concentration, and order of reagent addition. Chiral (helical) polyaniline complexes can be synthesized by addition of a chiral inducing agent (chiral acid) prior to polymerization, and the polyaniline helix can be controlled by the addition of the (+) or (−) form of the chiral acid. Moreover the quantity of chiral acid and the salt content has a significant impact on the degree of chirality in the final polymer complexes. The polyaniline and the template have been found to be mixed at the molecular level which results in chiral complexes that are robust through repeated doping and dedoping cycles.
