Latest Patents

Lessing is credited with 1 patent, titled “Hydrocyclone Separator.” The invention describes a separator with a head part, a tapered separation part, and an apex discharge part for underflow. The apex discharge part has a larger opening where it connects to the tapered section and a smaller opening for discharge. Its curved inner surface extends between the openings, ending at the discharge opening at a tangential angle between 0° and 40° relative to a plane transverse to the separator’s common symmetry axis. This geometry is intended to support the size classification of solid material in liquid suspension.
