A device for use in transporting particulate materials including: a conduit adapted for transporting particulate material from the first end to the second end of the conduit via an interior hollow chamber; a gas impermeable outer wall; a gas permeable inner wall; a compressed gas inlet nozzle which traverses the outer wall; a gas distribution chamber situated between the outer wall and the inner wall; and a gas pressure source attached to the gas inlet nozzle which conveys gas to the gas distribution chamber and through the gas permeable inner wall.

Particulate conveyor device and apparatus

A computer-aided chemical illustration system is disclosed. Techniques provided include: 1) efficient drawing of bonds; 2) drawing different bond types during a single mode; 3) determining bisect angles for bonds; 4) labeling atoms on the fly; 5) automatic alignment of atom labels; 6) custom alignment of atom labels; 7) changing the type, style, or orientation of an object while it is being drawn; 8) detection of ring structures; and 9) shifting bonds around on a ring.

Computer-aided chemical illustration system

A process for the preparation of a quaternary ammonium bisulfate which comprises the reaction of a quaternary ammonium alkylsulfate with sulfuric acid in a solvent mixture comprised of water and isopropyl alcohol, followed by the recovery of the solid quaternary ammonium bisulfate by crystallization from the reaction mixture.

Process for quaternary ammonium bisulfates
