Abstract: A fastening assembly includes a fastener having a head with an underside and an elongated shaft extending therefrom. The fastener constructed of at least one of a refractory metal and a superalloy. A washer includes a body with an upper surface and an opposing lower surface which defines opening portion for receiving the elongated shaft of the fastener therethrough. The upper surface of the washer forms diffusion bonds with the underside of the head of the fastener when the washer and the fastener are held in contact at temperatures in excess of 500° C.

Abstract: An aftertreatment subsystem includes first and second mounting interfaces, a fluid inlet and fluid outlet interface, and aftertreatment components, each having a central axis and axial extent. The central axes for the aftertreatment components are substantially parallel. End caps define fluid chambers that fluidly couple upstream aftertreatment component outlets with downstream aftertreatment components inlets. The end caps are positioned at a first or second end of the aftertreatment components. A first bracket joins the aftertreatment components at an axial position closer to the first end than to a center of the axial extent of any of the aftertreatment components and a second bracket joins the aftertreatment components at an axial position closer to the second end than to the center of the axial extent of any of the aftertreatment components. The first mounting interface is on the first bracket, and the second mounting interface is on the second bracket.

Abstract: An improved wafer holder design is described which has manufacturing and performance advantages over present state-of-the-art holders used in various wafer processing applications. The new wafer holder design incorporates a series of short radial grooves. The grooves extend from the base of a circular channel, which runs along the outside diameter of the substrate wafer recess, to a fixed radial location which varies based on wafer size and thickness. The grooves provide a slight overlap with the wafer to facilitate the free exchange of gases beneath the wafer necessary for wafer loading and unloading operations. The short length of the radial grooves make the wafer holder easier to manufacture and offer more robust performance compared to the present state-of-the-art holders.

Abstract: Several embodiments of medical ultrasound handpieces are described each including a medical ultrasound transducer assembly. An embodiment of a medical ultrasound system is described, wherein the medical ultrasound system includes a medical ultrasound handpiece having a medical ultrasound transducer assembly and includes an ultrasonically-vibratable medical-treatment instrument which is attachable to a distal end of the transducer assembly. An embodiment of a medical ultrasound system is described, wherein the medical ultrasound system has a handpiece including a medical ultrasound transducer assembly and including a housing or housing component surrounding the transducer assembly. A method for tuning a medical ultrasound handpiece includes machining at least a distal non-threaded portion of an instrument-attachment stud of the transducer assembly to match a measured fundamental frequency to a desired fundamental frequency to within a predetermined limit.

Abstract: An ultrasonic clamp coagulator assembly that is configured to permit selective cutting, coagulation, and fine dissection required in fine and delicate surgical procedures. The assembly includes a clamping mechanism, including a clamp arm cam-mounted at the distal portion of the instrument, which is specifically configured to create a desired level of tissue clamping forces. The balanced blade provides a functional asymmetry for improved visibility at the blade tip and a multitude of edges and surfaces, designed to provide a multitude of tissue effects: clamped coagulation, clamped cutting, grasping, back-cutting, dissection, spot coagulation, tip penetration and tip scoring. The assembly also features hand activation configured to provide an ergonomical grip and operation for the surgeon. Hand switches are placed in the range of the natural axial motion of the user's index or middle fingers, whether gripping the surgical instrument right-handed or left handed.

Abstract: A method of forming a discrete product from a continuous web of material. The discrete product having a discrete part and a minimum distance from the discrete part to its end edge. The method may include the steps of providing a continuous web of material, placing a discrete part onto the web of material, determining the location of the discrete part on the web of material, phasing a subsequent process in relation to the location of the discrete part and performing the subsequent process in such a way so as to preserve a minimum distance from the discrete part.

Abstract: A method for inducing strain on a workpiece includes the step of providing a testing apparatus having a first set of teeth and a second set of teeth. The workpiece is placed adjacent to the first or second set of teeth. The second set of teeth is disposed on a movable carriage which linearly reciprocates thereby allowing the first and the second sets of teeth to engage and disengage each other. A commanded position by time is provided to the carriage while the actual position by time of the carriage is measured. The first set of teeth are in communication with at least one load cell such that when the first set of teeth engage the second set of teeth, the load applied by the carriage is measured. The actual position by time data and the load data are manipulated to produce vast information pertaining to the workpiece.
