  • Patent number: 6341679
    Abstract: In a control unit for a torque converter with a lockup mechanism, the surface temperature of a clutch friction material in a lockup clutch is calculated with a surface temperature calculation unit B3, the surface temperature of the clutch friction material so calculated is compared with a predetermined first allowable temperature with a surface temperature comparison unit B4, and when the surface temperature of the clutch friction material is judged to have reached or exceeded the first allowable temperature, a friction material temperature reduction operating unit B5 is started to operate to reduce the surface temperature of the clutch friction material.

  • Patent number: 6340378
    Abstract: A process and apparatus for separating briquettes and fragments in a product stream resulting from briquetting direct reduced iron. Separating and cooling of the briquettes and fragments are carried out simultaneously in an initial step with use of separating means submerged in a cooling bath. The process enables use of less rugged apparatus following the initial step and the apparatus is not subjected to handling the product stream at the elevated temperatures at which briquetting is carried out. Capital expenditure and equipment maintenance is thus reduced.
