Separation of ferrous materials

A sorting apparatus is provided for sorting selected magnetically attractable articles from non-selected magnetically attractable articles in a stream of articles. A sensor generates sensor signals representative of a property associated with a selected class of magnetically attractable articles. A separator device includes an array of magnets. A controller receives sensor signals from the sensor, identifies a location within the stream of articles of a selected magnetically attractable article, and selectively activates one or more magnets of the array of magnets and thereby magnetically attracts the selected magnetically attractable article from a first trajectory into a second trajectory while allowing non-selected magnetically attractable articles to continue along the first trajectory.

MAGNETICALLY LEVITATING STERILIZING TOOTHBRUSH HOLDER
20220015533 · 2022-01-20 ·

A magnetically levitating sterilizing toothbrush holder with associated toothbrush comprises a holder generating a magnetic field and a toothbrush comprising a magnetic or ferromagnetic element. The holder and toothbrush are so configured that, when the toothbrush is placed in the holder, the force of gravity acting on the toothbrush is balanced in opposition to the magnetic force resulting from the interaction of the toothbrush's magnetic element with the holder's magnetic field, resulting in magnetic levitation of the toothbrush within the holder, thereby suspending the brush from all potentially contaminating surfaces. The holder further comprises a sterilizing ultraviolet light source, whereby the operational end of the toothbrush with its bristles is bathed in sterilizing radiation when the brush is suspended in the holder.
