Abstract: An example magnet assembly for a loudspeaker includes a first permanent magnet with a cuboid shape, the first magnet encompassing a central opening, and a second permanent magnet with a cuboid shape, the second magnet positioned coaxially within the opening of the first magnet and forming a rectangular-ring shaped first gap therebetween, the first and second magnets being axially poled in opposed directions. The assembly further includes a soft-magnetic base plate connected across one side of the first and second magnets, a soft-magnetic first pole piece having a first face and positioned on the first magnet, and a soft-magnetic second pole piece having a second face and positioned on the second magnet. The first pole piece and the second pole piece form a rectangular-ring shaped second gap between the first and second faces such that magnetic flux is focused in the second gap.

Abstract: A drive member for a cage of a spiral conveyor, the drive member comprising a cage-bar and an engagement member. The cage-bar comprises a ridge extending along a longitudinal axis of the cage-bar, the ridge being adapted to mate with an inner side of a conveyor belt. The cage-bar has a conical shape and a driving ridge in a single part with coating to protect against wear. At the belt entrance of the spiral conveyor, the sanitary monopiece direct drive cage-bar have an UHMW (Ultra-High-Molecular-Weight) polyethylene bloc overlapped to help engagement of the belt as specified by manufacturer of the belt. The custom bended shape of the cage-bar allows using several different conical angles to reduce belt tension. The monopiece cage-bar also allows applications where great temperature changes are required because the thermal dilatation will not causes gap in the driving ridge.
