Abstract: An aluminum adhering process and a vacuum transfer chamber for a metal thin film plating machine. The vacuum transfer chamber includes a vacuum transfer chamber and a pre etching reacting cavity installed in a periphery of and communicated to the vacuum transfer chamber. The pre etching reacting cavity is in a very high vacuum state. The vacuum transfer chamber is installed with a robot. The aluminum adhering process includes steps of: installing a locating frame in the vacuum transfer chamber and for storing an aluminum sheet; taking the aluminum sheet from the locating sheet then transferring the aluminum sheet to the pre etching reaction chamber; plasma bombarding the aluminum sheet in the pre etching reaction chamber; and transferring the aluminum sheet back to the locating frame after a layer of aluminum is plated on an inner wall of the pre etching reacting cavity.

Abstract: A composite structure comprising a layer of zeolite having a high silica to alumina ratio supported on a support layer acts as a separator in a redox flow battery. The zeolite can be either supported on a rigid substrate, such as alumina, or a flexible substrate, such as a polymeric film. The polymeric film, in particular, can be an ion exchange membrane such as Nafion. The zeolite layer with a high silica to aluminum ratio provides a long-lasting separator for redox flow batteries.

Abstract: An axial flow impeller includes a hub, at least three base blades, and a cover blade detachably mounted to each base blade. When the impeller is applied in a medium environment having a high density and viscosity, the impeller will meet the requirement only by virtue of the base blade with the cover blade being removed. When the impeller is applied in a medium environment having low density and viscosity, the cover blade can be mounted in the front and/or rear of the base blade in order to improve the efficiency of the impeller. In this case, the consumption of electrical power can be reduced significantly while producing an equivalent propulsive force, thereby being advantageous for energy conservation. Therefore, the impeller can be adaptable to different medium environments and efficiency requirements, and thus can have good adaptability, need minimal investment cost and can be convenient to use.
