Abstract: Apparatuses and methods for planarizing a microelectronic-device substrate assembly on a planarizing pad. In one aspect of the invention, material is removed from the substrate assembly by pressing the substrate assembly against a planarizing surface of a planarizing pad and moving the substrate assembly across the planarizing surface through a planarizing zone. The method also includes replacing at least a portion of a used volume of planarizing solution on the planarizing surface with fresh planarizing solution during the planarization cycle of a single substrate assembly. The used planarizing solution can be replaced with fresh planarizing solution by actively removing the used planarizing solution from the pad with a removing unit and depositing fresh planarizing solution onto the pad in the planarizing zone.

Abstract: To operate the air circulation and convey the stock flow of scrap material comminuted in the housing (1) of a hammer mill, the airflow generated by the blower effect of a rotor (2) and the stock flow passing through an upper classifying grate (4) are diverted by a deflector hood (8) and guided vertically downwards into a duct (6) that is separate from the housing (1). The stock flow is combined with the stock flow classified in the area of a lower classifying grate (5). The air flow is then guided in the circulating air and the combined stock flow is conveyed to a device (11) for further processing, sorting and/or conveyance.

Abstract: A double seam forming apparatus for applying end units to can bodies includes a can seamer (12) with a seaming cam (46). Seaming cam (46) includes a high dwell portion (56) which deforms responsive to force encounterred by tooling during forming of a can seam. A reinforcing pin (72) limits deformation of the high dwell portion to prevent damage. The high dwell portion of the cam includes a force sensor (20) which generates a signal responsive to strain of the high dwell portion due to applied force. The apparatus further includes a monitor apparatus (28). The monitor apparatus includes a controller (30) which includes a processor and a data store (32), and a host station (38). The monitor apparatus is operative to identify seam fault conditions and to store data concerning seamer conditions. The monitor apparatus also operates a can ejector (26) to divert cans identified as having defective seams.

Abstract: A mechanical press drive that uses a ballscrew apparatus to move the upper platen of a press upward and downward. A first coupling is connected to a screw of the ballscrew apparatus and connects the screw to one of a movable platen of a press or a stationary member of the press. A second coupling is connected to and couples a nut of the ballscrew apparatus to the other of the platen and the stationary member of the press. A drive motor is operably connected to one of the nut and screw and relatively rotates them to impart reciprocal motion to a movable press platen coupled to the other of the nut and screw. The two couplings cooperatively isolate the ballscrew apparatus from offset and moment loading that may occur during press operation.

Abstract: A hand held device for compressing used or empty household containers consists generally of a long, straight handle and a small non-slip base. The handle has a hole in the center to receive the top of the container. The handle has rounded points protruding from the bottom, near the hole that receives the container top. As one slowly pushes the handle downward the points push on the structure of the top of the container. This creates points of failure, and allows the container to be crushed downward in a simple, slow, smooth manner, requiring very little downward force. The non-slip base, where the container is placed before compressing, keeps the container from slipping during compression. Before the container is compressed, the cap is loosened to let air out as it compresses. Once it is compressed, the cap is tightened, so the container remains compressed.

Each refiner segment has a plurality bars and grooves for refining a lignocellulosic material and forming a path for receiving and transmitting steam generated during the refining process. A plurality of dams are disposed within the grooves to retard the movement of the lignocellulosic material. A partial height portion of each dam adjacent the trailing face of the bar provides a flow path for the steam.
