    摘要: Filtration device suited for concentration of liquid samples, particularly biomolecules, and a method of concentrating, desalting, purifying and/or fractionating liquid samples. In certain embodiments the device includes a housing having a sample reservoir, and two substantially vertically oriented and spaced apart membranes disposed in the housing. An underdrain is associated with each membrane such that fluid passing through each membrane flows through a respective underdrain into a filtrate collection chamber. The fluid that does not pass through the membrane is collected in the retentate collection chamber, and can be recovered such as by a reverse spinning step, achieving recoveries greater than about 90%. The substantially vertical orientation of the membranes increases the available membrane area by at least 2.7 times the area available in a conventional filter device. The two-panel configuration also maintains more available membrane area in use during the last stages of filtration than a one-panel configuration.

    摘要: The present invention is a safety system for use in conjunction with a control bar for a kite wherein the two front lines are secured by a front line swivel positioned between the bar and the kite. One front line terminates at the swivel and one extension of the other front line, the center line, travels through a central aperture in the swivel. The center line is then routed through an aperture on the control bar and terminated with an end that can be secured to the user either manually or by a leash arrangement. The swivel allows any twists that may form in the front lines to unwind. An increased diameter element located proximally of the swivel is configured to engage the center swivel, but is configured to pass through the aperture on the control bar. When the bar is released, sufficient slack is imparted into the remaining flying lines to effectively depower the kite while retaining attachment to the kite through the restrained front line.

    摘要: A technique for fabricating an MEA. The technique includes providing a polymer electrolyte proton conducting membrane, and then spraying a catalyst ink directly on the membrane to form a catalyst layer. In one embodiment, the catalyst ink includes the proper ionomer to carbon ratio, such as 0.8/1, for the desired fuel cell performance. In another embodiment, the catalyst ink includes too little ionomer for the proper ionomer to carbon ratio for the desired fuel cell performance. An ionomer layer is sprayed on the membrane before the catalyst layer to provide the proper final ionomer to carbon ratio.
