Abstract: The high temperature superconducting material is made from a base material having two opposing surfaces and including a high purity yttrium barium copper oxide compound having a YBa.sub.2 Cu.sub.3 O.sub.7-x (123) composition with silver oxide. The method of making the superconducting material includes controlling a temperature of each opposing surface of the base material to form a time-dependent spatial temperature gradient across the base material; measuring the time-dependent spatial temperature gradient, determining whether it is within a desired range and controlling it so that the time-dependent spatial temperature gradient remains within the desired range, thereby melt-texturing the base material while decomposing the silver oxide into silver and transforming the base material into quasi-crystalline superconducting regions having YBa.sub.2 Cu.sub.3 O.sub.7-x (123) composition, intrinsically non-superconducting material zones consisting of coherent yttrium-rich material having a Y.sub.2 BaCuO.sub.

Abstract: Bolted mounting assemblies for use between two mounted components wherein one of the components experiences vibration typically use rubber shock absorbers to dampen the vibration transfer between the components. The rubber shock absorbers are expensive and complicated to manufacture and are limited in flexibility control. The present invention overcomes this and other problems by providing an adhesive with damping capabilities between washers in a bolt assembly. The bolt assembly is used to mount first and second components with the washers therebetween. The adhesive is spaced a predetermined distance from a longitudinal axis of a bolt and has a non-uniform thickness which increases as the distance from the longitudinal axis increases to provide protection from bending loads about the axis. The washers with adhesive form a washer assembly with damping and flexibility characteristics controlled through variations in the design.

Abstract: An apparatus and method for preloading roller bearings which rotatably support a pinion shaft in a differential gear assembly includes a drive mechanism which selectively engages and rotatably drives the yoke of the differential gear assembly in a counterclockwise direction as viewed from the pinion shaft threaded end. A dead shaft engages the pinion shaft nut and rotates therewith. A brake is coupled to and selectively restrains or allows the dead shaft to rotate with the nut. Preventing the dead shaft and nut from rotating causes the nut to be threadingly received onto the pinion shaft and load the bearings. Disengaging the brake and allowing free rotation of the dead shaft and nut allows sensing of the bearing preload condition within the differential gear assembly housing.

The pinion feed driving assembly causes the cutting radius of the cutting tool to decrease as the machining head rotates. The pilot is attached to the bottom of the machining head to provide a means for centering the cutting tool. The depth gauge is disposed on the driving system and is electrically connected to the system controller. The depth gauge measures the distance between a valve seat and the cutting blade. The system controller includes memory and programming for controlling the operation of the cutting tool. An operator can input the parameters that define the geometry of the valve seat profile.

Abstract: A method of removal and insertion of a bearing insert from a skate wheel is performed utilizing a bearing insert tool. The bearing insert has a central axial bore corresponding to the diameter of a central axial bore of a spacing element. An annular groove is formed on an inner circumference of the spacing element. The bearing insert tool has a shaft containing spring activated nipples on a distal end from a head portion. A button on the tool operates the spring. To remove a bearing insert the button is depressed retracting the nipples. The shaft is then inserted within the central axial bore of the bearing insert and spacing element. The nipples are released and allowed to engage the annular groove. Force is exerted in an axial direction away from the skate wheel causing the bearing insert and spacing element to be removed from the hub of the skate wheel.

Abstract: Members of an assembly, a first of which has an aperture and a second of which is of deformable sheet-like material, are fastened together by piercing and deforming the second member using a punch and die to provide a pierced aperture having a peripheral wall of helical form analogous to a screw-thread, assembling the members together with the apertures aligned, inserting a tubular fastener having a head and a shank into the apertures so that the head abuts a face of the first member and the shank extends through the second member, and then expanding at least part of the shank within the pierced aperture of the second member and thereby causing the peripheral wall of the pierced aperture to impress a helical peripheral groove into the external surface of the shank of the fastener. The shank can be expanded by pulling a tapering mandrel head into or through it.

Abstract: A novel method and apparatus for uniformly polishing thin films formed on a semiconductor substrate. A substrate is placed face down on a moving polishing pad so that the thin film to be polished is placed in direct contact with the moving polishing pad. The substrate is forcibly pressed against the polishing pad with pneumatic or hydraulic pressure applied to the backside of the substrate during polishing. Additionally, a wear ring is placed on the polishing pad around and adjacent to the substrate and forcibly pressed onto the polishing pad with a downward pressure from a second source so that the wear ring is coplanar with the substrate in order to eliminate edge rounding effects.

Abstract: This is a system/method of clamping or securing or connecting one or more objects together in a wide variety of ways with the main means being a specifically designed bar and mated slot combination. While the main embodiment is the "Handy Table" project, there are many other ramifications of this invention. The bar and slot design can be altered to perform many other tasks where some way of attaching one or more objects to another need be accomplished. The main embodiment is, in my estimation, the most advanced type of work or project surface. The combination of a tri-sectional work surface, adjustable in a variety of ways, in size, in tilting, in multi-angle clamping capability, in precision height adjustment, and in the ability to transport the object being worked on easily, plus the addition of accessaries that enhance the overall capabilities of the "Handy Table", make it useable by many different professions and by the average project worker, be it man or woman, young or old.
