Abstract: A chomping bubble producing toy including a shaft secured between a bubble solution reservoir and a housing. The housing is the shape of a character and includes an upper and moveable lower jaw piece. A lever is secured to a connection rod within the housing, which connection rod is secured to the lower jaw about a rotational axle. When the lever is pulled, the connection rod moves upward, which pushes the lower jaw down about the fixed rotational axle.

Abstract: Systems and techniques can be used to extract solid material with an alcohol-based solvent. To subsequently recover the solvent after extraction, the solvent-wet solid material having undergone extraction can be desolventized. The solvent-wet solid material may be desolventized in multiple stages, either in a single vessel or in multiple different vessels, to generate multiple corresponding condensate streams containing alcohol and water vaporized from the solvent-wet solid material. By splitting desolventization into multiple stages, the composition of the condensate streams generated during desolventization can be individually controlled to benefit downstream processing. For example, the first condensate stream produced during desolventization may have a comparatively low amount of water whereas a second condensate stream produced during desolventization may have a comparatively high amount of water.
