| 20090246723 | METHOD AND HEAT TREATMENT APPARATUS FOR UNIFORMLY HEATING A SUBSTRATE DURING A BAKE PROCESS - A heat treatment apparatus and associated method are provided for heating a substrate. The apparatus includes a processing chamber containing a process space, first and second substrate supports, and first and second heating sources. The first substrate support is configured to support the substrate in a spaced relationship with the first heating source to define a heat exchange gap and to transfer heat energy through the heat exchange gap to elevate a temperature of the substrate to an offset temperature below a process target temperature. The second substrate support is configured to support the substrate in a spaced relationship with a second heating source to define a heat exchange gap between the second heating source and the substrate and to transfer heat energy through the heat exchange gap to elevate the temperature of the substrate from the offset temperature to the process target temperature in controlled increments. | 10-01-2009 |
| 20100266974 | Apparatus for preheating particulate material - A preheating apparatus for particulate material comprises a containment vessel, a floor ending in a central material discharge section, and a vertically oriented outer annular preheating section which circles the center section, with said annular preheating section having an outer wall and an inner wall having a lower side that is spaced above the floor to form an arch. A ram-type plunger feeder moves reciprocally from a first retracted position located closer to the outer wall to a second extended position located between the first retracted position and the material outlet of the chamber for contacting particulate material with said pusher face and moving particulate material under the arch and toward the material outlet. It has been discovered that in preheaters of this design the relative locations of the first retracted position of the feeder, the arch and the end of the sloped floor adjacent to the central discharge will have an influence on the movement of the particulate material toward the central discharge. | 10-21-2010 |
