Abstract:
A method for joining a valve member for use within a valve, the method including brazing a body portion having a head and a base, the base having a bore extending a depth therein, to a leg portion having a shaft, the shaft having a distal end, a proximal end opposite the distal end, and a plurality of legs extending radially and axially therefrom and away from the proximal end, the brazing including placing a braze material between the bore and the proximal end, inserting the proximal end into the bore such that a portion of an outer surface of the proximal end is adjacent to an inner surface of the bore, and heating at least the adjacent surfaces to a braze temperature.
Abstract:
Die Erfindung bezieht sich auf ein Verfahren zur Herstellung eines Instruments, insbesondere eines Dentalinstruments oder eines medizinischen Instruments, bei welchem ein Rohling 1 erzeugt wird, welcher nachfolgend zumindest teilweise mit abrasiven Partikeln beschichtet wird, wobei die abrasiven Partikel in einer Mischung mit Trägerpartikeln auf die zu beschichtende Oberfläche zugeführt und mittels eines Lasers 4 aufgeschmolzen werden.
Abstract:
A system 10 and method for laser cutting a plurality of parts, for example metal chassis components, using a plurality of laser cutting apparatuses is provided. The system 10 includes a plurality of the laser cutting apparatuses 14 disposed in a single enclosed cell 12 for simultaneously trimming multiple parts. The system 10 also includes at least one inner chamber 22 and at least one set of double doors 16, 18 for transferring the parts in and out of the enclosed cell 12 without any light escaping the cell 12. The parts are conveyed through the first door 16 to the inner chamber 22 while the second door 18 is closed, and through the second door 18 to the enclosed cell 12 while the first door 16 is closed. The system 10 also includes robots 24 continuously preloading and unloading the parts to maximize the laser trimming time.
Abstract:
A wellbore plug includes a first part, a second part and a rotary friction welded joint connecting the first part and the second part to form the wellbore plug. A method includes fusing the first part to the second part by rotating the first part relative to the second part while applying an upsetting force to generate friction between the first part and the second part to generate a work piece; and finishing the work piece to form the wellbore plug,
Abstract:
A method of repairing a metallic component (10) is disclosed. The method may include machining away a damaged first portion (38) of the component (10), and machining away a second portion (52) of the component (10) adjacent the damaged first portion, the second portion being subject to distortion resulting from solidification of molten weld material added to repair the damaged first portion. The method may also include inserting a dam (42) made of a high-temperature-resistant material adjacent the machined away second portion to contain molten weld material added to the machined away second portion. Oxy-fuel welding may be performed to at least partially fill the machined away damaged first portion of the component and the machined away second portion of the component, and final machining of the welded portions may be performed.
Abstract:
The following simplified summary is provided in order to provide a basic understanding of some aspects of the claimed subject matter. Its purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later. In certain embodiments a system for opening packages is provided comprising a conveyer for supporting or conveying a package, wherein the package comprises a surface material and a measurement zone wherein the package is inspected and measured for a cutting operation to thereby determine a process location comprising a location on the package for introduction of a cut to the surface material.
Abstract:

Abstract:
Es wird ein Verfahren zur Herstellung einer Rolle und eine Rolle zum Führen und/oder Stützen eines Strangs (5) einer Stranggießanlage mit einem einen Eisenwerkstoff aufweisenden Grundkörper (2) und mit einer eine Rollfläche (4) für den Strang (5) ausbildenden Schicht (3) aufweisend eine heterogene Aluminiumbronze gezeigt, wobei die Schicht (3) mit dem Grundkörper (2) über eine Auftragsschweißverbindung (6) mit dem Grundkörper (2) stoffschlüssig verbunden ist. Um eine hohe Standfestigkeit zu erreichen wird vorgeschlagen, dass die heterogene Aluminiumbronze mehrphasig ausgebildet ist.
