Abstract: In a capacitive deionization water desalination apparatus, the waterways of the cell are physically switchable between treatment-phase and purge-phase. In treatment-phase, the waterways conduct the flow of water thickness-wise, in-series, through the whole stack of electrodes and spacers. In purge-phase, the waterways conduct the flow of purge-water into the edges of the spacers, and along the spacers parallel to the plane of the spacers.

Abstract: A water treatment apparatus comprising a stack of circular electrodes with a central through hole, the electrodes are supplied with electricity so as to form anodes and cathodes in alternating intercalation. The anodes and cathodes so arranged to lie in such close-spaced parallel face to face relationship as to form a capacitive deionization cell. Water to be treated is passed from the outside of the stack, radially inward through between the electrodes into the central through hole and then axially out of the stack.

Abstract: The brake disclosed herein provides a linear brake kinematic over a wide range of wheel rim sizes. The brake provides for the same brake feel and response to the rider throughout actuation of the brake lever. Also, the brake feel and response may be designed to be the same even if a different wheel rim size is mounted to the bicycle. In an aspect of the brake, this is accomplished by forming a curved configuration, namely, a cam profile on upper portions of left and right brake arms. These upper portions of the left and right brake arms extend away from the wheel so that the cam profiles formed in the upper portions of the left and right brake arms may be made as long as necessary to accommodate the wide range of rim sizes.

Abstract: By combining lecithin, water and oil as the principal ingredients, a highly effective, uniform, widely dispersed, pan release spray product is achieved. Preferably, the lecithin is a dry, powdered lecithin. The lecithin is blended with the oil, water and/or alcohol to form a stable emulsion that exhibits superior pan release properties. Furthermore, the lecithin emulsions are easily formulated with a variety of blending agents to make flavorful salad dressings, marinades, and pet flavor enhancing products, as a non-aerosol, finger pump based product or as an aerosol product. By selecting an appropriate propellant, the product is non-flammable as well.
