  • Patent number: 9718703
    Abstract: An apparatus for continuously removing an oily pollutant from polluted water includes an absorbent unit and a suctioning unit. The absorbent unit is made of a hydrophobic and oleophilic porous material and is able to absorb and to separate the oily pollutant from water when the absorbent unit is placed in the polluted water. The suctioning unit is coupled to the absorbent unit and is operable for providing a suctioning force to the absorbent unit so as to continuously remove the oily pollutant absorbed by the absorbent unit. A method for continuously removing the oily pollutant from the polluted water is also provided.

  • Patent number: 6832422
    Abstract: An apparatus for assembling a post-CMP cleaning brush. The post-CMP cleaning brush is provided with a brush core and an outer brush, and the outer brush is provided with a hollow portion. The apparatus comprises a base, a fixed member, a sliding member, a plurality of posts, and an actuating device. The base holds the brush core and the outer brush, and the fixed member is disposed on the base. The sliding member is disposed on the base in a manner such that it is located at the opposite side of the fixed member relative to the outer brush disposed on the base. The posts, disposed on the sliding member, pass through the fixed member and the hollow portion of the outer brush so as to assist the brush core in passing through the hollow portion of the outer brush. The actuating device connects with the brush core so as to pass the brush core through the hollow portion of the outer brush and separate the posts, inserted into the outer brush, from the outer brush.
