摘要： An elongated flexible member including a plurality of ceramic segments, each segment having at least two opposite surfaces that are flat and parallel. The segments are aligned in stacked relationship with their flat faces in abutting face-to-face relation and forced toward each other in the direction of their composite length with a force which is sufficient to maintain the segments in compression when subjected to conditions of thermal change and/or flexing of the member during use. A method for making the ceramic member is disclosed.

摘要： A vacuum drainage device for the forming fabric on a Fourdrinier machine which includes a transversely extending vacuum box and a plurality of stationary stepped blades having a flat support surface and a recessed trailing surface which normally does not support the forming fabric. Both water drainage and wire screen motion is effected by a series of these stepped blades. A hydrodynamic nip is formed between the forming fabric and the trailing surface when vacuum is applied by the vacuum box, thereby effectively limiting the drainage suction to the distance between the nip and the leading edge of a succeeding blade.

摘要： A twin-wire papermaking machine which includes a dewatering and press section, the dewatering section employing suction boxes within the loop of one of the forming wires, and blast boxes within the loop of the other forming wire. The boxes have convex domes which cause the two wires to move in a serpentine configuration and are positioned to provide continuous support thereto. The dewatering section may also employ opposed foils, press cylinders, and suction cylinders located opposite to grooved cylinders.

摘要： A method and apparatus for making nonwoven fabrics wherein water and fiber stock is delivered to a Fourdrinier wire moving endlessly through a stock tank, the fibers being deposited on the wire in a forming zone and the water passing through said wire into a suction box comprising a plurality of adjacent and individually controlled compartments, each of said compartments having a bottom sloping in a direction transverse to the direction of travel of said wire and each of said compartments having a flow restricting device such as a baffle mounted therein, wherefore a substantially uniform pressure differential through the moving wire across its width is obtained so as to result in an even deposit of fibers thereon.

摘要： A DRAINAGE FOIL WHICH INCLUDES A NON-FLEXING FOIL SECTION HAVING A TOP SURFACE LEADING PORTION AND A TOP SURFACE TRAILING PORTION. THE FOIL SECTION IS MOUNTED ON A LOWER SUPPORT SECTION BY A PLATE SPRING LOCATED BENEATH THE TOP SURFACE LEADING PORTION OF THE FOIL SECTION AND A CAM BAR ADJUSTMENT SYSTEM LOCATED BENEATH THE TOP SURFACE TRAILING PORTION. ADJUSTMENT OF THE CAM BAR SYSTEM RESULTS IN ANGULAR TILTING OF THE FOIL SECTION ABOUT THE PLATE SPRING SUCH THAT THE LEADING PORTION OF THE FOIL SECTION REMAINS IN CONTACT WITH THE FOURDRINIER WIRE BUT BENDING OF THE FOIL SECTION IS AVOIDED.

摘要： A suction box for a papermaking machine wherein the holes through the suction box cover include, at least the leading and trailing edges thereof, concave edges which prevent wear of the forming wire and prevent rewetting of the paper web.
