Abstract:
A method of forming an elongated tubular blank into a tubular structural component having a predetermined outer configuration, the method comprising: providing a shape imparting shell formed from a low permeability, rigid material which includes an inner surface defining the predetermined shape, plugging the open ends of the tubular blank, placing the plugged blank into the shell, and forming the tubular blank into the tubular component by inductively heating axial portions of the blank by axially spaced conductors adjacent the shell while or before forcing gas at a high pressure into the plugged blank until the blank conforms to at least a portion of the inner surface of the shell to form the structural component.

Method Of Forming A Tubular Blank Into A Structural Component And Die Therefor
A method of forming an elongated metal blank into a structural component having a predetermined outer configuration. The method includes providing a shape imparting cavity or shell section formed from a rigid material which includes an inner surface defining the predetermined shape, placing the metal blank into the cavity or shell section, and forming the metal blank into the component by heating axial portions of the metal blank and forcing a fluid at a high pressure into the metal blank until the metal blank at least partially conforms to at least a portion of the inner surface of the cavity or shell section to form the structural component.

Abstract:
A system and method for producing locally austempered ductile iron includes a computer program for closely controlling the heating and cooling of an iron part or workpiece. The process allows for the austempering of a relatively low cost iron workpiece to produce significantly higher quality end products. The locally austempered regions may be formed to a substantial controlled depth.

Abstract:
A method of monitoring a heating cycle of an induction heating system wherein an inductor encircles a metal workpiece and an alternating current is applied through the inductor from a power supply during the heating cycle. This method comprising the steps of generating an analog signal representative of the voltage across the inductor, as the voltage varies during the heating cycle by changes in the electromagnetic characteristics of the workpiece as the workpiece is being heated; digitizing the voltage representative analog signal; creating a trace of the digitized voltage representative analog signal, with the trace being indicative of the electromagnetic characteristic of the workpiece as sensed by the inductor voltage during the heating cycle; and, comparing the created trace with a preselected pattern. This method can be performed with the workpiece moving through the inductor during said heating cycle and when the heating cycle includes a number of sub-cycles when the power supply is energizing the inductor separated by periods when the power supply is not energizing the inductor.
Induction Heating And Package Sealing System And Method
An induction heating package sealing system includes a control which applies full power to an inductor of a first period and reduces power gradually for a second period. A seal temperature profile gradually approaching a temperature goal is thereby achieved which provides for a more uniform seal.
