ABSTRACT:
There is provided a novel and improved core element for a catalytic converter characterized in that the core element has a corrugated thin metal strip with bent tab members at each end, such tab members being in two portions. These two portion sandwich the ends of the corrugated thin metal strip therebetween and provide a convenient means for welding the ends of the corrugated thin metal strip to the tab members. A plurality of such corrugated strips with the tab members attached are tightly spirally wound about a central post or pin and the tab members are dimensioned to overlap and ultimately define a shell segment. The shell segments define a core which is encased in a suitable housing to form a catalytic converter which may be electrically heatable. An electrically heatable catalytic converter is especially useful to remove pollutants from internal combustion engine exhaust gas.
