Publication number: 20080040944Abstract: 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.Type: ApplicationFiled: August 14, 2007Publication date: February 21, 2008Applicant: American Dryer CorporationInventor: DENNIS SLUTSKY

Patent number: 6148543Abstract: 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.Type: GrantFiled: December 6, 1999Date of Patent: November 21, 2000Inventor: Daniel R.

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.Type: GrantFiled: September 10, 1998Date of Patent: August 29, 2000Assignee: ASM America, Inc.Inventor: Ivo Raaijmakers
