Abstract:
An electrostatic spray dryer for drying liquid into powder including an elongated body defining a drying chamber, a spray nozzle assembly at one end of the drying chamber and a filter element housing and powder collection chamber at an opposite end. A non-structural non-metallic liner is disposed within the elongated body in spaced relation to an inner wall surface for defining an internal drying zone. The liner is releasably supported within the body for enabling selective removal and replacement following a particular usage. The illustrated elongated body has a modular construction comprising a plurality of modules, with at least one being selectively removable and replacement for altering the length of the drying chamber for a particular spray application. The liner also is replaceable with a liner of a length corresponding to the altered length of the drying chamber or with a different diameter for a particular usage.

Abstract:
The present inventions relate to the formation of a thin polymer film on a substrate. Apparatus is described for transforming a solid polymer resist into an aerosol of small particles, electrostatically charging and depositing the particles onto a substrate, and flowing the particles into a continuous layer. Apparatus is further described for transforming solid resist into an aerosol of small particles by heating the resist to form a low viscosity liquid such as is compatible with nebulization and applying the techniques of jet or impact nebulization and aerosol particle sizing to form the aerosol. A method is further described of using ionized gas to confer charge onto the aerosol particles and using a progression of charging devices establish an electric field directing the flow of charged particles to the substrate. The progression of charging devices and associated apparatus results in high collection efficiency for the aerosol particles.
Abstract:
A system for fluid transport is provided where a quantity of fluid is held in a reservoir. A droplet generator is employed to generate droplets from the fluid, for example a nozzle-based system or a nozzleless system such as an acoustic ejection system. A generated droplet has a trajectory whereby it arrives at a target. A circuit is used to modify one or more characteristics of the generated droplet in a way which increases the likelihood that the droplet will not splash or bounce when it arrives at the target. The circuit may in different embodiments control the speed of the droplet or the Weber number of the droplet. The circuit may create an electric field in an area of space where the droplet passes. The circuit may change the droplet by causing it to contact ions.
