Abstract: Device and method for treating mammalian bone deficiencies, defects, voids and conformational discontinuities produced by congenital deformities, osseous and/or soft tissue pathology, traumatic injuries and functional atrophy is described. The device is a one piece molded body member composed of four substances, each of which contributes to the device, a specific requirement (or requirements) for osteogenesis and/or osteoneogenesis. Taken as a whole, the functions of these device constituents are integrated into a single body member which, when implanted into a bone defect, has the capacity to restore functional architecture and mechanical integrity, initiate osteoinduction and osteogenesis, and maintain the biological processes of bone formation and remodeling while the host organism is simultaneously biodegrading the body member.

Abstract: A mill (10) for grinding garbage is disclosed including an octagonal shaped grinding chamber (26). Grinding rotors (48-50) are rotatably fixed to a rotatable shaft (44). An impeller rotor (51) is also rotatably fixed to the shaft (44) below the grinding rotors (48-50). The impeller rotor (51) discharges a stream of air, entrapped material, and projectiles into a projectile deflection device (182) which includes an upwardly sloping bottom plate (202) which deflects the projectiles into an end plate (204) to reduce the kinetic energy thereof. The air stream and entrapped material pass from the projectile deflection device (182) into a plenum (210) which reduces the velocity of the air stream to release much of the entrapped material, with the material release being enhanced by baffles (224) providing a tortuous path for the air stream in the plenum (210) before it enters a cyclonic material separator (216).
