Abstract: Moistened powder and granular materials, such as produced by an extrusion granulator, are disintegrated into uniformly sized and shaped granules by an apparatus having a cylindrical housing and a working plate rotatably disposed in the housing in coaxial alignment with said housing, with an opening at the center of the working plate. A working fluid is introduced into the interior of the housing above the working plate through a wall of the housing and moistened powder and/or granular raw materials are supplied into the housing onto the working plate. The treated materials are discharged through the central opening in the working plate.

Abstract: The inspection car is intended to inspect the lower side of the bridge construction of a high level road from above the high level road as well as from the ground and it comprises a swingable and extensible boom vertically swingably pivoted on a rotatable pedestal rotatably mounted on the chassis of the car about the vertical rotational axis of the pedestal, a reciprocal boom pivotally mounted on the tip of the swingable and extensible boom through a saddle, and an extensible inspection passageway pivotally connected to one end of the reciprocal boom, the passageway being swingable between a position parallel to the reciprocal boom and a position at right angle thereto while it is allowed to be rotated about the longitudinal axis of the reciprocal boom, a plurality of hydraulic cylinder means for the movement of the respective components listed above, and a control device for detecting the amount of movement of each component and controlling the movement thereof on the basis of the detected amount of movement
