PURPOSE:To prevent creep of a car by means of a high idle circuit by combining an electromagnetic clutch with a belt-type stepless speed change gear and perfectly cutting-off said clutch in P range or N range through electric-current control. CONSTITUTION:As for a stepless speed change gear 2 consisting of a switching part 3 for advance and retreat, belt-type stepless speed-change part 4, final re...

A continuous flow device for separation of particles of differing densities in a centrifugal force field. Very small particles of differing densities that are normally very difficult or impossible to separate in the useful commercial gravity separation devices can be separated because of the increased settling force due to the centrifugal force field and also the buoyant force on the particles of ...

The invention relates to a computer tomography apparatus for determining the absorption distribution in a relevant zone of a body, this zone being irradiated by unattenuated radiation, while the part of the body which is situated outside this zone is irradiated at the most by attenuated radiation. The radiation outside the relevant zone is attenuated in accordance with the invention by means of ab...
