A system and a method for separating and recycling magnets made from rare earth elements from an article of manufacture used an alignment device to property position the rare earth magnet for processing. Once proper alignment is made, a separating device removes the magnet and a portion of the article. A heating device demagnetizes the magnets and vibration causes the magnets to separate from the portion of the article. Electromagnets remove the portion of the article and the rare earth magnets pass through for reclamation.

Metal tableware articles are separated from trash as the trash is deposited into a trash container through a removable cover having brackets supporting a shaft of a magnetic bar assembly for rotation on a horizontal axis. The shaft is rotated from outside the cover by an axially movable rotatable pin having a knob on its outer end and extending through the side wall of the cover for releasably engaging one end of the shaft. When the knob and pin are retracted axially, the bar assembly may be lowered from the cover for cleaning. The bar assembly has axially spaced magnetic plate units each having a pair of generally triangular metal plates with flat corner surfaces and with a panel of magnetic material of the same shape sandwiched between the plates. The bar assembly is spaced above the bottom surface of the cover for protection of the bar assembly.

A tramp metal separation assembly comprises a housing, a core rod and a sleeve tube. The housing includes a first and second discharging areas and a feeding area. The core rod includes a first and second non-magnetic sections and a magnetic section. The core rod is mounted on the housing in a way that the first and second non-magnetic sections correspond respectively to the first and second discharging areas and the magnetic section corresponds to the feeding area. The sleeve tube includes a first and second portions. The sleeve tube is sleeved outside the core rod in a way that it is moveable between a first position, wherein the first portion corresponds to the magnetic section and the second portion corresponds to the second non-magnetic section, and a second position, wherein the first portion corresponds to the first non-magnetic section and the second portion corresponds to the magnetic section.

Disclosed is an apparatus for capturing bioaerosols. More particularly, the apparatus for capturing bioaerosols includes a sprayer configured to spray a buffer solution for protecting aerosol particles in a form of droplets; and a capturer into which air including the droplets and the aerosol particles is introduced and in a capture solution in which the aerosol particles are captured, wherein discharge members provided with a plurality of nanostructures are provided on a surface of the capturer to charge the aerosol particles. Due to such a configuration, high discharge efficiency can be anticipated even at a low voltage without damage to aerosol particles.

A magnetic separator for the dry separation of material particles having different magnetic susceptibilities includes a rotatable cylinder that has a stationary magnetic device arranged therein, and extending essentially across its length. A sorting chamber is furthermore provided for which extends along at least a portion of the outer surface of the cylinder in the circumferential direction of the cylinder and parallel to the longitudinal axis of the cylinder. The magnetic separator includes means for the dispersed output of material particles into the sorting chamber, as well as means for generating a stream of conveying air in the sorting chamber. A motor for rotating the cylinder around its longitudinal axis is included, wherein, during operation, the outer surface of the cylinder is moved by the rotation of the cylinder in a direction essentially perpendicular to the direction of the stream of conveying air.
