Abstract: An improved waste feed arrangement for feeding waste into a rotary combustor including a stepped support frame and a ram which pushes the waste through a doorway into the rotary combustor, the ram slidably engaging an upper step of the support frame and has a bracket on the outboard end to which a cam follower is rotatably attached, the cam follower rolls on a lower step of the support frame and a hydraulic cylinder is connected between the bracket on the ram and a bracket disposed in the support frame in such a manner that the hydraulic cylinders piston rod pushes the ram away from the doorway as it extends from the hydraulic cylinder providing a smaller, totally covered hydraulic cylinder and piston rod and an improved waste feed system.

Abstract: A device for supplying feedwater to, and conveying feedwater from, a shaft tube assembly (20,22) of a machine having a rotary part, which assembly (20,22) has a longitudinal axis about which the assembly (20,22) rotates together with the rotary part, the device being composed of a housing which includes a cylindrical casing (2) having a cylindrical passage extending between its axial ends and a lateral feedwater passage (6) communicating with the cylindrical passage, a conduit member (8) having a second feedwater passage (10) and coupled to one axial end of the casing (2) to form a sealed joint with the casing (2), the conduit member (8) being positioned relative to the casing (2) such that the second feedwater passage (10) communicates with the cylindrical passage, and a closing member (12) coupled to the second axial end of the casing (2) to form a sealed joint with the casing (2), the closing member (12) having a circular opening coaxial with the cylindrical passage of the casing (2 ), the housing being co

Abstract: A radial seal for use in connection with a cylindrical rotatable member passing through a stationary member which includes a circular floating shoe mounted to the stationary member and surrounding the rotatable member in order to accommodate axial, lateral and rotational movement of the rotatable member while still providing an effective seal.
