  • Patent number: 6817821
    Abstract: The invention is an improved reflow tool for performing a reflow process on a wafer. An input robot may be used to transport wafers from an input carrier to an oven where a reflow process is performed. After processing the wafers in the oven, the wafers are transported to a storage carrier. In a preferred embodiment, the storage carrier includes a plurality of left and right slats that use chamfer tabs and centering tabs to precisely position the wafer as the wafer is loaded into the storage carrier. The storage carrier may be part of a buffer indexer that also includes an actuator for vertically positioning the storage carrier. An output robot may be used to sequentially remove the wafers from the storage carrier and to place the wafers in an output carrier. In another preferred embodiment, the power from a main power supply to the reflow tool is monitored and an uninterruptible power supply is used to power the oven and buffer indexer if power is lost.

  • Patent number: 4806056
    Abstract: Apparatus and a method for delivering materials such as comminuted rubber tires as a secondary fuel to a combustion chamber of a furnace or kiln. A hopper includes a variable speed electric motor-driven screw conveyor, and a control system provides a variable frequency alternating current to the motor of the screw conveyor to deliver a metered amount of fuel from the hopper. A blower and a nozzle assembly may be used to entrain the fuel in a stream of air and carry the fuel to the combustion chamber where it is required. The fuel is delivered in metered quantities in response to the required firing rate of the furnace or kiln. A second metering device provides metered quantities of material which can be carried by the fuel to be taken into a high temperature environment to be decomposed or burned. The apparatus is mounted on a transportable platform.

  • Patent number: 4634329
    Abstract: A loading device for a horizontal continuous furnace for the heating of glass plates comprises a roller conveyer (6) as part of a continuous conveying system. Support strips (12-15, 32-35) can be lowered and are arranged between conveying rollers (7) of the roller conveyer at a feed station (A). The glass plates (2, 3, 4, 5) are placed on the raised support strips (12-15, 32-35) and are lowered onto the conveying rollers at a preset time by simultaneous lowering of all support strips. Each support strip (12-15, 32-35) is supported independently of the other support strips on separate lifting devices (16-19, 36-39). These lifting devices (16-19, 36-39) are controlled by reflecting photoelectric barriers (22-25, 42-45) respectively dedicated to each support strip such that each support strip (12-15, 32-35) is individually raised to an upper position as soon as a glass plate transferred to the conveying rollers (7) has left the area of that support strip.
