The invention relates to an improved method and apparatus for forming metallized iron by direct reduction of particulate iron oxide. The spent reduction gas is recycled from the reduction furnace (10) through a cooler- scrubber (34) and a catalytic gas reformer (38). In the cooler scrubber (34), the spent reducing gas interacts with scrub water. Dust having an affinity for sulfur is recovered from...

Disclosed is a process for fabricating a composite polycrystalline diamond or cubic boron nitride (CBN) compact. Briefly, the process is conducted by mating a pre-formed sintered polycrystalline diamond or CBN compact and a plastically deformable support, and subjecting the mated composite compact to elevated temperature and pressure conditions sufficient to plastically deform the support into att...

A device for holding the braking force of a motor vehicle has a braking force holding valve (22) in a brake operating fluid circuit.

The invention relates to a method for measuring a length, in particular for determining an overlap length on a spooled/reeled material strip. In order to be able to detect the overlap length automatically, it is proposed that the front end of the material strip is detected on the drum by means of a detector and at the same time the associated angular position of the drum is measured, that after th...
