Abstract: A process for the production of ethanol, useful as a fuel, from various cellulose-containing materials by saccharification, fermentation and distillation of the resultant fermented ethanol-containing beer to recover ethanol; which comprises the formation of a slurry of the material being saccharified by recycling a portion of the resultant fermented ethanol-containing beer back to the incoming material being subjected to saccharification whereby the concentration of ethanol during fermentation and subsequent distillation treatment is substantially increased over that utilizing no recycling treatment, the process being carried out at under normal atmospheric conditions.

Abstract: A process and apparatus for chromatic separation of components by flowing fluid in contact with material wherein the fluid flows downwardly through a column comprising a plurality of contacting chambers each of which contain material to be contacted, and wherein each of the chambers are selectively subjected to treatment by said fluid, the material preferably comprising adsorptive, gel or ion exchange substances, or the like, and filtration material for purification and as a continuous or discontinuous process.

Abstract: A massager which comprises a resilient massaging roller, the periphery of which is studded with flanged protuberances, the roller being removably mounted for rotation on spaced upright members secured to a base member or platform, the latter being movable back and forth by the user to position and manipulate the roller during the massaging operation.

Abstract: A process for making alcohol from cellulosic material by hydrolyzing the material to sugars and subjecting the resultant reaction mixture to digestion and fermentation to convert the sugars to alcohol. The process comprises sterilization of the cellulosic material; concurrent digestion and fermentation of the sterilized mixture to produce alcohol using innoculum comprising cellulase enzyme and yeast, vacuum stripping to recover the alcohol, and recovery of innoculum for reuse.
