| 106 | Organic aerogel microspheres | US586038 | 1996-01-16 | US5908896A | 1999-06-01 | Steven T. Mayer; Fung-Ming Kong; Richard W. Pekala; James L. Kaschmitter |
| Organic aerogel microspheres which can be used in capacitors, batteries, thermal insulation, adsorption/filtration media, and chromatographic packings, having diameters ranging from about 1 micron to about 3 mm. The microspheres can be pyrolyzed to form carbon aerogel microspheres. This method involves stirring the aqueous organic phase in mineral oil at elevated temperature until the dispersed organic phase polymerizes and forms nonsticky gel spheres. The size of the microspheres depends on the collision rate of the liquid droplets and the reaction rate of the monomers from which the aqueous solution is formed. The collision rate is governed by the volume ratio of the aqueous solution to the mineral oil and the shear rate, while the reaction rate is governed by the chemical formulation and the curing temperature. | ||||||

The ceramic suspension typically comprises a colloidal suspension of a metal oxide, wherein the metal of the metal oxide is an alkali metal, alkaline-earth metal or a rare-earth metal, but preferably is magnesium, calcium or a rare-earth metal. The non-polymeric organic compound is added to the suspension in an amount effective to substantially disperse and reduce the rate of dissolution of the ceramic particles, such as from about 0.01 weight percent to about 5.0 weight percent. | ||||||
| 112 | Emulsifying milling machine and process for emulsifying | US528774 | 1995-09-15 | US5622650A | 1997-04-22 | John K. Rourke |
| A mill for emulsifying immiscible fluids comprises a mill body having a cylindrical cavity extending therewithin, a fluid inlet at one end of the cavity and a fluid outlet near the other end, both in fluid communication with the cavity. The mill further comprises a stator having a first stator surface, and a rotor assembly having a rotor mounted on a shaft for rotation in the cavity, where the rotor has a first milling surface which faces the first stator surface. Between the first stator surface and the first milling surface is a first fluid milling space. The stator includes at least one annular row of stator projections extending from the first stator surface into the first fluid milling space, and the rotor includes at least one annular row of rotor projections extending from the first milling surface into the first fluid milling space. The annular rows of rotor projections are concentrically adjacent to the annular rows of stator projections within the first fluid milling space. The fluid inlet delivers the hydrophobic and hydrophilic fluids to the first fluid milling space, such that, upon rotating the rotor assembly, the fluids are pumped from the fluid inlet into the first fluid milling space where they are emulsified, and are then pumped from the first fluid milling space to the fluid outlet. The mill thus utilizes a single pass continuous feed process to produce fluid emulsions of a substantially uniform particle size. | ||||||

In the preparation process, the gel is aged. When elevated temperatures of at least about 40.degree. C. up to the boiling point of the solvent are used in aging, the gel can be aged for a period of at least about 24 hours. At temperatures from ambient up to about 40.degree. C., the gel is aged for a minimum of about 48 hours. | ||||||
