  • Publication number: 20090260255
    Abstract: A drying apparatus for silicon or alumina-based plate elements, such as the type for electronics, or other types of plates for electronics, comprises an oven that develops along a path and having a drying chamber that develops along the path, on a relative lying plane. The oven has an entrance (21) into the chamber and an exit from the chamber. The plate elements are fed into the chamber from the entrance to the exit along the path by means of a translation unit in order to effect a drying cycle. The translation unit comprises planar support elements able to advance along the chamber, which are disposed along the path and orthogonally thereto and inclined downwards with respect to the lying plane of the chamber by a relative angle. The plate elements are disposed on the planar support elements so as to define, during normal use, a passage way for the drying air, also below the plate elements.

  • Publication number: 20080040944
    Abstract: The present invention is a method of drying clothing. A user inserts clothes into a clothes dryer and initiates a normal drying cycle. To initiate a normal drying cycle, the user purchases time for a normal cycle and an optional reverse cycle using a payment interface. The dryer subsequently operates in a normal drying cycle. Next, a reverse drying cycle is initiated, if selected and purchased by the user, to help avoid roping and balling up of their clothes. After the amount of predetermined time purchased for the normal and reverse drying cycles has elapsed, the dryer is turned off. Because a reverse cycle is used, this method of drying clothes prevents roping and balling up of clothes to achieve better drying results in pay operated drying machines.

  • Patent number: 6421931
    Abstract: In the present method of drying iron ore pellets, e.g., magnetite pellets, moisture-containing iron ore pellets are formed into a bed comprising a multiplicity of the pellets. A current of drying gas is forced through the bed of pellets to at least partially dry some of the pellets. At least one jet of a drying gas that contains added oxygen is directed onto the bed of pellets so to impinge upon a surface of the pellet bed thereby providing kinetic energy for directing oxygen including the added oxygen into the pellets so as to enhance the conversion of magnetite to hematite. Moisture can be added to heated air that is then blown through jet nozzles onto the pellet bed or circulated back to an earlier drying stage and passed through the bed.

  • Patent number: 6148543
    Abstract: In the present method of drying iron ore pellets, e.g., magnetite pellets, moisture-containing iron ore pellets are formed into a bed comprising a multiplicity of the pellets. A current of drying gas is forced upwardly through the bed of pellets to at least partially dry some of the pellets. A plurality of pipes, each having an opening such as an elongated slot provides counter-current jets of a drying gas above the bed. The drying gas jets are directed downwardly so as to impinge on the upper surface of the bed through which the current of drying gas rises. The bed of pellets is thus dried with the current of drying gas flowing through the bed from below as well as the jets of drying gas impinging onto the upper surface of the bed. In a preferred form of the invention, in a second stage downwardly directed jets of drying gas are used together with a downward current of drying gas to further dry the pellets before they are fired.

In one embodiment, a substrate and support structure combination is lifted after high temperature processing to a cold wall of a thermal processing chamber, which acts as a heat sink. Conductive heat transfer across a small gap from the substrate to the heat sink speeds wafer cooling prior to handling the wafer (e.g., with a robot). In another embodiment, a separate plate is kept cool within a pocket during processing, and is moved close to the substrate and support after processing. In yet another embodiment, a cooling station between a processing chamber and a storage cassette includes two movable cold plates, which are movable to positions closely spaced on either side of the wafer.
