  • TUNABLE STIFFNESS BONE ROD
    Publication number: 20210393300
    Abstract: A tunable stiffness bone rod promotes the healing of fractured bones, such as tibia bones. The tunable stiffness bone rod includes a hexagonal shape that has variable levels of stiffness upon application of an axial force. The axial force will begin a low stiffness movement of the bone rod until a threshold is met. Upon reaching the threshold, the stiffness of the bone rod increases to lessen additional longitudinal movement caused by the axial force on the bone rod.

  • Device for turning over and back-mixing moist material
    Publication number: 20060050609
    Abstract: A turnover device (1) to turn over and mix back moist material (2), in particular sewage sludge, in a drying installation (3) is equipped with at least one shovel (7). The moist material (2) is spread out for drying on floor (4) in the drying installation (3). The shovel (7) is rotatable within a circumference around an axle (8). Directly outside the circumference and essentially above the layer of material a retention device (9) is installed for the moist material (2) and interacts with the shovel (7).
