Abstract: The tool mounting arrangement employs a bushing within a recessed end of a shaft. The bushing has three lobes with inclined surfaces which abut against an internal conical wall of an annular mounting portion on the end of the shaft. A threaded screw passes through a washer and the grind wheel in non-rotatable relation into threaded relation in the bushing. Turning of the screw causes the bushing to be pulled in a direction out of the shaft so as to radially deform the annular mounting portion into uniform contact with the bore of the grind wheel while the grind wheel is simultaneously abutted square to the shaft axis. The annular mounting portion is provided with equi-spaced circumferentially disposed notches to permit passage of the lobes upon insertion of the bushing into the recess at the end of the shaft. One or more set screws is also provided in the shaft to prevent rotation of the bushing within the recess of the shaft.

Abstract: A method of making a microsurgical cutter from a flat planar substrate having a top surface and a bottom surface comprises the steps of (a) forming a photoresist mask layer on the top surface in the pattern of the microsurgical instrument, the mask layer having an edge portion formed in a predetermined pattern therein; and then (b) etching isotropically the top surface of the substrate through the top surface to the bottom surface so that the top surface and bottom surface meet at a cutting edge portion, with the cutting edge portion having a configuration corresponding to the edge portion of the mask layer. The substrates may be formed from semiconductor materials such as silicon, silicon carbide, sapphire and diamond.

Abstract: A device for removing a child resistant closure from a container, including a tab to receive the protrusion of a closure of the line-up-the-arrows type, a recess to receive the closure adjacent the tab, an inclined side of the recess to bear against the closure and maintain the tab in engagement with the protrusion, and an end of the device opposite the tab to receive a force. The recess is such that it can accept varying sizes of closures. Applying a force to the forcereceiving end in the downward direction levers the tab upward to pry the closure off the container. The tab is positioned on the device in such a way that the user can readily see the engagement of the tab with the closure protrusion.

Abstract: The opener/closure of the present disclosure relates to devices permitting the opening or closing of twist cap containers.
