Abstract: A chainless electric cycle design that allows a rider/user to pedal a pedal generator to create an electric transmission energy source that either charges the battery or partially powers a hub motor, discharges the battery to the hub motor contained within one of the wheels, allows the user to set a desired level of resistance from the pedal generator using controls oriented about the handlebars, allows the user to activate the hub motor using a speed controlling device oriented about the handlebars, and allows the user to charge the battery by connecting to a standard 110V/220V AC power supply. A chainless cycle is a cycle where the input power from a rider is not converted into output power by the rear wheel through a gear and chain system connecting the pedals to the rear wheel.

Abstract: A process for the purification of sucralose in sucralose-containing feed streams is disclosed. The process includes multiple liquid-liquid extraction steps; optionally, a concentration step; multiple crystallization steps; optionally, a chromatography step; and various recycle steps.

Abstract: This invention relates to a crystallization process for sucralose in which a mother liquor is obtained by separating crystalline sucralose from the remaining liquid. A portion of this mother liquor is returned to the same crystallization stage; the amount returned is adjusted so as to maintain the overall related substances level in the process below levels at which yield declines significantly.
