Abstract: A heat and/or mass transfer process and apparatus for treating various types of materials. A heat and/or mass transfer process includes causing a gas to impinge upon a flowing material, wherein the gas velocity having a component tangential to the flow direction of the material can be characterized such that a fluctuating velocity is superimposed upon the mean velocity of the material in the flow direction. The process further includes effecting velocity fluctuations by means of a traveling tangential acoustic wave while a steady overall gas flow is maintained, and controlling the gas velocity by means of a vernier valve. By using fluctuating velocity superimposed upon the mean velocity, an effective thermal and mass transfer resistance of the boundary layer can be reduced, as well as reducing the pressure fluctuations.

Abstract: A method of sterilizing musical instruments is provided. More particularly, a method of sterilizing musical wind instruments is provided for sterilizing, or at least sanitizing, musical wind instruments without damaging or degrading components of such instruments constructed of cloth, wood, plastic, rubber or fibrous materials. The method of the invention uses a gas diffusion process and a gas sterilant, such as ethylene oxide. A musical wind instrument is placed in a gas diffusion bag and a sterilizing atmosphere is created within the gas diffusion bag by releasing ethylene oxide into the gas diffusion bag at a sufficient concentration to act as a sterilant. Ethylene oxide is heated to an appropriate temperature and maintained at such temperature for a sufficient time to achieve sterilization, or at least sanitization, of the musical wind instrument contained therein.

Abstract: The present invention provides methods and apparatus for freeze drying in which a solution, which can be a radioactive salt dissolved within an acid, is frozen into a solid on vertical plates provided within a freeze drying chamber. The solid is sublimated into vapor and condensed in a cold condenser positioned above the freeze drying chamber and connected thereto by a conduit. The vertical positioning of the cold condenser relative to the freeze dryer helps to help prevent substances such as radioactive materials separated from the solution from contaminating the cold condenser. Additionally, the system can be charged with an inert gas to produce a down rush of gas into the freeze drying chamber to also help prevent such substances from contaminating the cold condenser.

Abstract: An vertical dryer (10) is provided having a plurality of individual dryer decks (12-18) including alternating fan and heater decks (14, 16), an air circulation assembly (11), and an upright, common plenum chamber (26) in communication with the decks (12-18). The assembly (11) is operable to create a continuous drying air stream which passes upwardly in countercurrent flow relationship to product on the decks (12-18). Also, the assembly (11) serves to pass the drying air stream into, through and out of the plenum (26) at the level of each heater deck (16); in the plenum (26), the air stream velocity is decreased, causing particulate fines to fall out of the stream for collection. The use of the common plenum (26) also allows independent control of the decks (12-18) in terms of air flows therethrough and recirculation characteristics.
