Abstract: Disclosed is a continuous process for the purification of steviol glycosides extracted from the dried stevia leaves using continuous simulated moving bed processes and nanofiltration without the addition of organic solvents to obtain a purified steviol product comprising sweet steviol glycosides. The sweet steviol glycosides can be used as substitutes for caloric sweeteners in beverages and in other food items.

Abstract: A propulsion and exercise device for attaching to a conventional wheelchair having: at least one drive wheel operably interposed between the rear set of wheelchair wheels. A telescoping mast may connect the drive wheel axle to pedals to permit the pedals to be selectively moved from a stowed position to an extended position for use. Power is transmitted from the pedals to the drive wheel through a chain drive that passes over idler sprockets that maintain the chain length during adjustment of the telescoping mast.

Abstract: The “Pedalong” is a propulsion and exercise device attaching to a conventional wheelchair having: a drive support system attaching to the wheelchair frame and supporting a drive main frame; a propulsion system including an input unit operated by the user proximate the front end; and further including at least one drive wheel operably interposed between the rear set of wheelchair wheels. a power transmission assembly interposed between the input unit and the drive wheel to transmit power from said input unit to the drive wheel when engaged by the user to propel the device. The propulsion system can be: belt driven; chain driven; shaft driven; fluid power driven; or electrically driven. The input unit is mounted at a forward end of the main frame, so as to be adjustable in length.
