Abstract: A superconductor device includes a high superconductivity transition temperature enhanced from the raw material transition temperature. The superconductor device includes a matrix material and a core material. The enhancing matrix material and the core material together create a system of strongly coupled carriers. A plurality of low-dimensional conductive features can be embedded in the matrix. The low-dimensional conductive features (e.g., nanowires or nanoparticles) can be conductors or superconductors. An interaction between electrons of the low-dimensional conductive features and the enhancing matrix material can promote excitations that increase a superconductivity transition temperature of the superconductor device.

Abstract: There is disclosed a window blind suitable for use in arch-type and semi-circle windows, including windows having a curved side defined by a radius, including irregularly shaped windows having a curved side with a varying radius. The apparatus is designed to provide both privacy and shade, and may also be readily opened and closed. A plurality of slats is pivotal in relation to a mounting base or base, and can be deployed into an array to cover the entirety of a semi-circular window. The apparatus features a mounting base, which serves as the foundation for the complete apparatus. The mounting base typically is generally rectilinear, so to be suited for fastened attachment (as by mounting brackets and screws, or the like) to the “flat” or straight side of an arched or roughly semi-circular window. Other principal components of the apparatus include a plurality of slats which are pivotally attached to the mounting base.

The tool ends of the first and second arms are moveable between a first position, wherein the tool ends of the first and second arms are adapted to disengage the tooth, and a second position, wherein the tool ends of the first and second arms are adapted to engage the tooth. A decorative element is releasably attachable to the decorative end of the first and second arms.

Abstract: This invention is a new high wheel speed grinding process that uses only one very hard grade resin bonded grinding wheel of the desired abrasive grit size for the surface finish required, where simultaneously with the grinding of a workpiece the wheel face is conditioned and trued by a truing element heated to a temperature between 250.degree. F. and 1200.degree. F. at the truing rates required to provide grinding at quantitatively predictable desired and constant unit volume energy and metal removal rate values. Because of the hard grade wheel specification, the wheel face would quickly revert under any job situation to a dull wheel face without this conditioning and truing. Under any forseeable job situation, conjoint control of the temperature of the truing element and the truing rate controls wheel wear rate.

Abstract: A centerless grinding system comprises a driven grinding wheel, a driven regulating wheel, and a work rest blade for centerless grinding of a workpiece supported by the work rest blade between the grinding wheel and the regulating wheel; means for determining the rate of reduction of the workpiece radius while it is being ground; and means responsive to the rate of reduction of the workpiece radius for controlling the ratio of the power consumed in removing workpiece material to the rate of removal of workpiece material by the grinding wheel. The regulating wheel is preferably fed toward the grinding wheel to feed the workpiece into the grinding wheel. In a similar center-type grinding system, the workpiece is mounted on spindles or chucks which are movable toward the grinding wheel so that the workpiece can still be fed by the regulating wheel.

Abstract: A method of grinding a workpiece which is susceptible to deflection and/or deformation when grinding is carried out by relatively infeeding a grinding wheel to keep the wheel face and work surface in relative rubbing contact at an interface region, the method comprising continuously determining the force exerted by the wheel on the workpiece at the interface region as grinding conditions change, continuously applying to the workpiece at least one counterbalance force which in equivalent effect is opposite in sense to the determined force, and variably controlling the counterbalancing force to maintain its effective magnitude equal to the magnitude of the determined force.

Abstract: Grinding control methods and apparatus pertaining generally to maintaining the shape and sharpness of a grinding wheel, despite the tendency of the wheel face to deteriorate from the desired shape and sharpness, as grinding of a given workpiece or a succession of workpieces proceeds. Generally, as a common denominator of the novel features disclosed, a "conditioning element" is brought into rubbing contact with the face of the grinding element under specially controlled and unique conditions to (i) restore the desired shape (conventionally called truing), or (ii) to establish the desired degree of sharpness (conventionally called "dressing"), or to accomplish both (i) and (ii) simultaneously. The methods and apparatus disclosed include creating the aforesaid controlled rubbing contact either while the grinding wheel is free of grinding contact with a workpiece or simultaneously while grinding is occuring, and then either continuously or intermittently.

Abstract: A grinding system is controlled by (1) determining the exact nature of a power function relationship between (a) the rate at which material is removed from one of the surfaces at a rubbing interface and (b) the feed rate at which the rubbing surfaces are fed into each other, for a particular grinding operation, i.e., a particular grinding wheel and other specified conditions affecting the rate of material removal at the rubbing interface; and (2) controlling, measuring or setting the material removal rate or the feed rate in such a grinding operation in accordance with said power function relationship.

Abstract: A system for finish grinding a workpiece monitors the actual radius of the workpiece as the finish grinding progresses; feeds the grinding wheel into the workpiece at a feed rate which decreases, preferably at an exponential rate, as a desired final radius of the workpiece is approached; and terminates the feeding of the grinding wheel at the desired final radius of the workpiece. In a preferred embodiment, the grinding wheel is trued, simultaneously with the finish grinding, by feeding a truing element into the grinding wheel at a rate that varies as a function of the decreasing rate at which the grinding wheel is fed into the workpiece.
