  • Patent number: 10626358
    Abstract: The present invention provides for methods and at least partially automated devices suitable for producing a transplantable cellular suspension of living tissue suitable for promoting tissue regeneration in an epithelium-related procedure, as well as compositions produced therefrom. Tissue regeneration in humans is extremely limited and constitutes a major challenge to the repair of damaged organ function. Wound treatment is a typical area where tissue regeneration is required. Wounds (lacerations or openings) in mammalian tissue can result in tissue disruption and coagulation of the microvasculature at the wound face.

  • Patent number: 10487835
    Abstract: A cutter assembly and high volume submersible shredder pump. These are for reducing the size of solids within a liquid which is to be pumped by chopping, grinding, shredding or cutting. An improvement over prior designs employs a cutting assembly having a rotary cutter and a cup-shaped, concave, plate cutter having a circular horizontal cross-section. The plate cutter is adapted for mounting to an intake opening of a stationary volute, associated with a shredder pump. The cutting assembly has cutting lobes having a grooved surface which mate with corresponding grooves of the shaped, concave, plate cutter. As a result, many more cutting surfaces are provided which more effectively and quickly shred the solid materials within the liquid to be expelled.

  • Publication number: 20140263781
    Abstract: A bone mill assembly provides a drive motor with a reducer. The drive motor is connected to a non-rotating coupler which is connected to a main drive cutting head. A mill housing consists of a manual feed chute or a pneumatic feed chute that shuttles the bone stock onto the main drive cutting head of the mill. The bone stock is ground to a smaller particle size and then shuttled by rotation onto a straight secondary blade. This chops the particle size even smaller and then is sized by an internal window sieve. If the particle size is small enough, the bone particulate passes through the sieve into a collection pan. If the particle size is too large, it will then be rotated back up within the housing to be processed again by the main cutting head. Different sizes of the main cutting head are used for customer specific applications.

  • Publication number: 20110186666
    Abstract: A pulp lifter assembly for a rotary grinding mill includes an outer pulp lifter having walls defining a pulp lifter chamber and an outlet opening for radially inward discharge of slurry from the pulp lifter chamber, and an inner discharger disposed radially inward of the outer pulp lifter and circumferentially offset from the outer pulp lifter. The inner discharger defines a passage for conveying slurry substantially radially inward. A transition discharger is disposed radially between the outer pulp lifter and the inner discharger. The transition discharger has a first wall bounding an interior space and a second wall dividing the interior space into first and second regions. The second wall includes a guide that bounds a channel connecting the outlet opening of the outer pulp lifter to the passage defined by the inner discharger.

  • Publication number: 20110036935
    Abstract: An agitator mill has a grinding vessel and an agitator shaft arranged such that it can be driven to rotate therein. Fixed at the end of the agitator shaft is a last agitator disc, on which is fixed a substantially cylindrical cage having apertures. Arranged inside the cage is a screening device. The distance between a second to last agitator disc and the last agitator disc is such that a braided flow forms, while avoiding a preliminary screening of grinding stock on one hand and auxiliary grinding bodies and coarse grinding stock particles on the other hand. Formed in the last agitator disc are passages through which the grinding stock passes together with the auxiliary grinding bodies, at which time a separation of the auxiliary grinding bodies and the coarse grinding stock particles takes place within the separating chamber formed by the last agitator disc and the cage.
