Abstract: A method of manufacturing endodontic files involves a chemical milling process to yield endodontic files having a desired taper. The process involves the steps of (a) providing a metallic rod having a cutting portion with a polygonal cross section; (b) torsioning the rod so as to form helical cutting surfaces in the cutting portion of the metallic rod; and (c) chemically milling the cutting portion of the rod so as to taper the cutting portion. The rod may be formed of any desirable metallic material, for example stainless steel or a nickel-titanium alloy.

Abstract: The present invention relates to an active mount system in which a vibration sensor such as a force gauge or an accelerometer senses vibrational forces transmitted through a resilient mount by a load such as a machine. The invention further includes a control signalling device that processes and transmits the sensed signal to a force transducer such as an electromagnet which supplies an attenuating force to the resilient mount in response to the signal.
