Patent number: 7335857Abstract: A rod-shaped heating element with a tubular carrier element attached to a cylindrical carrier ring and to the rod-shaped heating element using a magnetic forming process, the carrier ring and the rod-shaped heating element being within the tubular carrier element with the outer circumferential surface of the carrier ring contacting the inner circumferential surface of the tubular carrier element. As a result of the parts having been joined by magnetic forming, they are in a plastically deformed state which is free of thermal treatment effects and scuffing.Type: GrantFiled: March 22, 2004Date of Patent: February 26, 2008Assignee: Beru AGInventor: Martin Eller

Patent number: 7084374Abstract: A heating flange especially for the preheating of the intake air of an internal combustion engine with a frame (8), a supporting ceramic element (2) with a heating band (10) fitted thereto. The supporting ceramic element 2 is held in the frame at an inner side of the frame, and a support spring (1) is arranged between the supporting ceramic element (2) and the inner side of the frame. The support spring (1) is a leaf spring which is straight in the non-stressed state, and sits under an initial prestess between the supporting ceramic element (2) and the inner side of the frame. As a result of this configuration, low friction arises between the supporting ceramic element (2) and heating band (10), as well as leaf spring (1), which reduces failures due to vibratory loading, and a defined initial spring tension with a defined spring deflection is produced.Type: GrantFiled: December 11, 2003Date of Patent: August 1, 2006Assignee: Beru AGInventors: Steffen Geiger, Thomas Giffels, Martin Eller
