Abstract: A process and system for continuous assay and removal of toxins from tobacco. Products such as tobacco contaminated with mycotoxins, particularly aflatoxins, and benzpyrene and its precursors, are subjected to treatment, generally in a solvent medium, to decontaminate the tobacco of the toxin. Continuous monitoring of all harmful toxins eluted from the cleaning solvent is performed by immunoantibody ultraviolet fluorescence, for example. A quality-control process ensures removal of harmful toxins from tobacco before further processing. Decontamination of extracted solvent streams and re-additives ensures safe reuse or disposal of the solvents and re-additives.

Abstract: Accommodative intraocular lens systems having two lenses or one lens and one ring connected by sections of the same material are manufactured from a sheet material, and then the connecting sections are bent to align the optical axis of the lenses. Accommodation is achieved either when the two lenses are moved closer and further from each other, or when the single lens is moved closer and farther from the retina of the eye.
