Abstract: A coating apparatus includes a rotary cup for forming beads and projecting them radially outwardly, and one or more collection basins surrounding the bead forming cup. The cup is adjustably rotatable about its central axis, and the collection basins are independently rotatable and positioned to collect the beads projected from the cup. The coating apparatus further includes an elevation adjustment system for axially adjusting the alignment of the cup with respect to the selected collection basins. The rotational speeds of the cup and the collection basins are selected so as to minimize the impact of the beads against a gelling solution in the collection basins. In use, a supply mixture is introduced into a mixing chamber of the cup. As the cup spins, the coated particles are propelled upwardly by the centrifugal force from the mixing chamber along the inner surface of the cup, and are projected radially outwardly, as beads, into the gelling solution in one of the selected basins.

Abstract: An abrupt pressure change applied to a dispersion of core and shell material in a liquid carrier medium encapsulates the core material within the shell material. The method and apparatus of this invention permit a wider range of core and shell materials to be utilized than was possible with prior art methods including materials which previously have not been usable as shell materials. Materials in solid, liquid, gas or multiphase form may be encapsulated. Additionally, capsules are produced in a small fraction of the time required by prior art methods. The total time to perform the encapsulation may range from a few seconds to only a few minutes. The abrupt pressure change may be applied to the dispersion by either a piston or ultrasonic apparatus in both batch, semi-continuous, and continuous processes. Recycling of the capsules through the apparatuses permits adjustment of the capsules' characteristics as well as formation of multiple core capsules.

Abstract: An apparatus for manufacturing capsules which causes a solution of thermo-gelling material to gelatinize, and then drys the gel, whereby the process of manufacturing capsules is less affected by drying conditions, thus providing capsules of uniform wall thickness without wrinkles. In the apparatus of this invention, circulating capsule pins are dipped in the solution of thermo-gelling material, thus the solution adheres to the pins, and, the pins are rotated upside down, thus thickness of the solution adhering to the pins becomes uniform. Then, the pins are retained in the vessel maintained at a higher temperature than the gelling temperature of the solution, and the solution adhering to the pins is accelerated to gelatinization. The formed gel is dried in a drying device, and the dried gel bodies, i.e. capsules, are removed from the capsule pins.

Abstract: A method and apparatus for forming microcapsules from a fluid medium containing living culture material by the atomization of the medium and the treatment of the atomized droplets with a treatment fluid. A medium under pressure enters a chamber having a wall with a plurality of orifices formed therein. A vibrator vibrates the chamber. As the medium passes through the orifices the exit stream vibrates and forms small droplets. The droplets fall into a collection vessel on the other side of the wall, which contains treatment fluid for hardening the droplets into microcapsules. A flow of treatment fluid may be maintained through the collection vessel to prevent clumping of the droplets and to transport the hardened microcapsules for harvesting. Preferred operating pressures, orifice size and chamber configuration are shown.

Abstract: A method for compressing gases in a contained volume consisting of hollow glass microspheres is described. The gases are compressed under high pressure and can be easily handled and stored. The gases to be compressed and contained in the microspheres are used as blowing gases to blow the microspheres.The hollow glass microspheres are made by forming a liquid film of molten glass across a coaxial blowing nozzle, applying the blowing gas at a positive pressure on the inner surface of the glass film to blow the film and form an elongated cylinder shaped liquid film of molten glass. A transverse jet is used to direct an entraining fluid over and around the blowing nozzle at an angle to the axis of the blowing nozzle. The entraining fluid as it passes over and around the blowing nozzle fluid dynamically induces a pulsating or fluctuating pressure field at the opposite or lee side of the blowing nozzle in the wake or shadow of the coaxial blowing nozzle.
