Abstract: The present invention discloses a combination unit and method of multiple membrane shells. The combination unit of multiple membrane shells is formed by bundling multiple membrane shells in parallel, wherein the raw water port and the concentrated water port of each of the membrane shells are respectively connected and sealed with the raw water port and the concentrated water port of the adjacent membrane shells to form the shared raw water port and the shared concentrated water port which are respectively connected with the raw water pipeline and the concentrated water pipeline. Since each of the combination units of multiple membrane shells is provided with the shared raw water port and the shared concentrated water port, it is adequate to finish the assembly of the shared raw water port with the pipeline and the assembly of the shared concentrated water port with the pipeline in the engineering installation. The combination unit of multiple membrane shells can be placed horizontally or vertically.

Abstract: Disclosed is a sliding and rotating apparatus for connecting two components of a device, such as a portable electronic media player, and a device having the same. The apparatus provides has a base member, a sliding member, and a rotating member. The sliding member is coupled to the base member so as to permit sliding thereon in a first linear direction and between first and second positions, and the rotating member rotationally coupled to the sliding member. The rotating member and base member are configured such that when the sliding member is forced into the second position the rotating member is rotated in a first angular direction. The apparatus also may contain a sliding mechanism that biases the apparatus in either the first or second position.
