摘要： A concrete stabilization system which includes a number of subsystems to provide a complete reuse and reclaiming of all concrete which remains unused at the end of the production day, and also reclaims all constituents of washout concrete from a number of concrete mixer trucks following the washing out process. A tower is provided for vertical and tilting motion of a material handling bucket, and a stationary mixer for stabilizing concrete and constituent material for reuse with fresh concrete batches at the start of the next production day or up to four days later. The fully automated system includes a start sequence initiated by the operator of the truck, and the process is then fully automated by a process controller which may be monitored off-site. The method includes a number of loop cycles, such as truck discharge and washout cycles, a stationary mixer load cycle, a water scan cycle which determines if the reused wash water contains excessive solid constituents, which are stored in the stationary mixer at intervals, so that the slurry water can continue reuse as wash water. The stabilization loop continually and automatically monitors the hydration state of the concrete in the stationary mixer and a chemical additive for retarding the hydration of the concrete is added to maintain the fluidity and plasticity of the concrete. The concrete is always ready for use because the chemical additive, a sugar based derivative, only retards the setting of the concrete for a short period.

摘要： An orthopedic treatment apparatus has a frame having a first movable platform having a platform frame movably attached to the frame for a reciprocating motion on a first pivot in a generally vertical motion. The first movable platform is also movably attached to said platform frame for a generally horizontal reciprocating motion on a second pivot. A first drive motor is attached to the frame and coupled to the first movable platform for driving the platform in a reciprocating motion relative to the frame while a second drive motor is attached to the first movable platform frame and coupled to the platform for moving the platform in a generally horizontal reciprocating motion relative to the frame. A second platform is movably attached to the frame and movable relative thereto and is driven by a third drive motor attached to the frame and operatively coupled to the second platform to move the platform relative to the frame in a generally oscillatory controlled pattern so that the orthopedic treatment apparatus moves plural portions of a patient through a plurality of compound motions which are adjustable as to cycle time for each motion which motions occur about pivots projected to regions within the spinal column.
