Abstract: Methods and systems used to extract lipids suitable in production of biofuels from a fermentation broth may include using heat to pre-treat the fermentation broth in order to more easily extract a product from oleaginous microorganisms in the broth. Additionally or alternatively, a combination of enzymes including amylase, 1-4 mannosidase, and 1-3 mannosidase may be used to break down cell walls of the oleaginous microorganisms. Residual broth water may be recycled and used as imbibition water for washing a process feedstock to extract sugar.

Abstract: A disposal-bag system attached to or formed at least partially by a disposable object (e.g., a diaper) includes a container that houses a disposal bag folded into a compact arrangement. The container is generally thin and flat and sized for storing the bag, and the bag is sized for holding the disposable object that the system is used with. And the bag is at least partially removable from the container so that the disposable object can be placed into it for disposal. In use, the container is opened, the bag is extended from the container and opened, the disposable object is grasped by reaching through the bag, the bag is inverted to now hold the disposable object, and the bag is closed and disposed of. In this way, the disposal-bag system provides a convenient, sanitary, and self-contained method of disposing of soiled diapers or other disposable objects.

Abstract: In one form, the disclosure describes a lathe apparatus and method for manufacturing a product with a non-axisymmetric shape from a workpiece, such as a toric contact lens, comprises a spindle for rotating the workpiece about an axis of rotation, a cutting tool, a two-axis bed for supporting the cutting tool and for moving the cutting tool along a predetermined path adjacent the workpiece as the spindle rotates the workpiece, and a mechanism for oscillating the cutting tool along an oscillation axis as the two-axis bed moves the cutting tool along the predetermined path, wherein the oscillation axis is oriented at a non-zero angle with respect to the axis of rotation. Preferably, the non-zero angle is about 45.degree.. In a second form, a lathe apparatus comprises a rotary bed for arcuately moving a cutting tool adjacent a workpiece and a mechanism for translationally reciprocating the cutting tool as the cutting tool is arcuately moved adjacent the workpiece.
