  • Patent number: 7325329
    Abstract: A salad spin-drier with a bowl of glass or ceramic so that part of the water collection bowl, which until now has been purely functional, may be simultaneously used as a serving bowl for the salad. The salad bowl as is standard apart from the bowl has a lid in which a drive mechanism having a rotary drive plate with a cord drum and a pull cord may be set into rotational movement by a pull grip. The rotary drive plate with tabs engages into suitable ribs on the spin-drier basket. The spin-drier basket has a bearing recess which rests on a bearing cam. The bearing cam is separated from the bowl centrally on a plate. The bowl has a planar inner base on which the plate rests, and by way of an abutment edge limiting the plane base one achieves a central mounting of the plate. For the simplified removal of the plate these may have suitable openings easier gripping. A rubber-elastic rest is on the underside of the plate and serves as scratch-protection and slip-protection.

  • Patent number: 6691720
    Abstract: A system for processing a workpiece includes an inner chamber pivotably supported within an outer chamber. The inner chamber has an opening to allow liquid to drain out. A motor pivots the inner chamber to bring the opening at or below the level of liquid in the inner chamber. As the inner chamber turns, liquid drains out. Workpieces within the inner chamber are supported on a holder or a rotor, which may be fixed or rotating. Multi processes may be performed within the inner chamber, reducing the need to move the workpieces between various apparatus and reducing risk of contamination.
