A medication disposal apparatus and method of use with multiple stages of conversion operable to render a controlled substance useless.

The invention relates to a device and a method for the dissociation of tissue. In one embodiment, the device has at least one dissociation unit, for receiving a tissue sample, which is disposed at least partially in a pot-shaped cell strainer. In addition, the invention relates, in one embodiment, to a device and a method for the dissociation of tissue, the tissue being dissociated by a grinder having mutually movable rows of teeth which cut the tissue when moving past each other in the one direction and grind the tissue when moving past each other in the opposite direction.

The present disclosure relates to a method for use in installation of a mill liner, the method including (a) retaining a mounting bolt at least partially within a liner opening extending through the mill liner, (b) positioning the mill liner against a mill shell so that the retained mounting bolt is aligned with a mill shell opening extending through the mill shell, (c) selectively coupling an extraction tool to the mounting bolt, the coupling performed by an operator outside of the mill shell, (d) detaching the mounting bolt from the liner using the extraction tool; (e) pulling the mounting bolt through the mill shell opening so that at least a portion of the mounting bolt protrudes outside of the mill shell, and, (e) securing a fastener onto the mounting bolt to thereby attach the mill liner to the mill.

The present invention relates to a method for preparing a non-acid-treated eco friendly cellulose nanocrystal and the cellulose nanocrystals prepared by the same. The methods for preparing the non-acid-treated cellulose nanocrystal and extracting the cellulose nanocrystal from cellulosic materials of the present invention are eco-friendly methods, compared with the conventional preparation method for cellulose nanocrystal based on acid-hydrolysis; are efficient due to the total energy saving process; are easy to utilize side products; and are characterized by high yield to produce the target cellulose nanocrystal. The nanocrystal prepared according to the present invention exhibits equivalent or higher aspect ratio, yield and crystallinity than the cellulose nanocrystal prepared through acid hydrolysis, and has remarkably excellent thermal stability, so that it can be effectively used for the production of membranes, electrical and electronic parts, substrates, heat insulating materials, and reinforcing materials required for durability against heat.

Systems and methods for downsizing tires are disclosed. An automated downsizing apparatus comprises a cradle, mandrel table, cutting apparatus, and a control unit. A tire mounted on the cradle may be received by the movable and rotatable mandrel table, and positioned for engagement with the cutting apparatus. A user may customize a cutting configuration to be executed by the control unit. The control unit positions the mandrel table and cutting apparatus to remove portions from the tire, according to the cutting configuration. During operation, one or more system parameters may be monitored to determine compliance with the selected configuration, and the automated execution may be manually overridden.

A crushed polycrystalline silicon lump is provided in which a surface metal concentration is 15.0 pptw or less and preferably 7.0 to 13.0 pptw, and in the surface metal concentration, a surface tungsten concentration is 0.9 pptw or less and preferably 0.40 to 0.85 pptw, and a surface cobalt concentration is 0.3 pptw or less and preferably 0.04 to 0.08 pptw.

Methods, systems, and apparatus for winnowing. In one aspect, a method includes loading an initial material into a winnowing system via a feed member; feeding the material into a fluidically accelerated winnowing cavity, where the initial material impacts at least one plate member to yield chaff material and processed material, and where the processed material and the chaff material circulate in the winnowing cavity; and separating the chaff material and the processed from the winnowing cavity based on density. Other aspects include yielding intermediate material, where the intermediate material reimpacts the at least one plate member until yielding chaff material and processed material, preprocessing the initial material, controlling the flow of initial material into the winnowing cavity with a feed gate, where the chaff material egresses the winnowing cavity via a chaff chute, where the chaff material collects in a collection cavity, and/or more.

Systems for shredding fibrous material are described. In some embodiments, the system includes a cart that includes a hopper that includes an auger motor for shredding fibrous material and a blower motor configured to blow the shredded fibrous material onto structures for fireproofing. The cart may include a handle, one or more wheels, and/or forklift apertures to aid in transport.

A plastics recycling preparation container canister includes a stationary disc configured with cutting teeth disposed on an axial surface thereof, the stationary disc disposed substantially orthogonal to an underside of a hinged lid for the container. The container canister also includes a spinning disc configured with cutting teeth disposed on an axial surface thereof, the spinning disc disposed on a sidewall of the container. A ramp for directing plastics to be shredded to the spinning disc is implemented followed by the stationary disc swung into a parallel position to the spinning disc in a sandwich configuration around the plastics to be shredded. The stationary disc and the spinning disc are separated by a space configured to accommodate the respective cutting teeth thereof and a space for shards of the plastic consumer recyclable. The cutting teeth of both discs are shaped like a parrot's beak comprising a rhinotheca tomium cutting surface.
