Abstract: A non-pyrolytic cigarette substitute device which, in response to suction supplied by a user, delivers to the user a nicotine-simulating vapor mixture having a cigarette-like taste and aroma. The device has absorbed therein a solution of a volatile nicotinomimetic agonist in an amount effective for its released vapors to satisfy the physiological needs for nicotine of the user, and volatile palatability enhancing agents in amounts effective for their released vapors to neutralize any unpleasant taste and aroma of the nicotinomimetic agonist vapors and to impart a cigarette-like taste and aroma to the released vapor mixture.

Abstract: A process for the recovery and purification of waste gelatin, especially from the manufacture of soft gelatin capsules includes the steps of effecting dissolution of the gelatin and other water-soluble components of the waste in a solvent such as deionized water such that a gelatin-containing solution dispersed within the remaining components of said waste is formed, permitting the dispersion to settle into an upper oil phase and a lower solvent based gelatin-containing solution phase, separating the lower phase from the upper phase, optionally hot filtering the lower phase to remove traces of the remaining components of the upper phase, and diafiltering the lower phase to remove the active ingredients, glycerin, and other water-soluble components and to provide a recycled gelatin solution.
