| 20120125466 | APPARATUS AND METHOD FOR SURFACE TREATMENT IN A FURNACE - The present invention relates apparatus and methods for treating the surfaces of substrates in a furnace to enhance the subsequent deposition of thin films or to enhance the reaction of the surfaces with gas phase components. Exhaust systems and methods of their use allow the exhaust gases to be conveyed to proper gas treatments facilities. Door seal and inert gas purge systems allow the furnace to be operated safely and minimize the reaction of the process gases in the door seal region. | 05-24-2012 |
| 20120085281 | APPARATUS WITH MULTIPLE HEATING SYSTEMS FOR IN-LINE THERMAL TREATMENT OF SUBSTRATES - The present invention relates to in-line equipment used to process substrates. In some applications, the equipment is used in the in-line manufacture PV cells or modules. In some embodiments, a heating system is provided that comprises a plurality of heating technologies for the heat treatment of substrates wherein a first heating system is used to rapidly raise the substrate temperature to the desired set point and a second heating system is used to maintain the substrate at the temperature set point throughout the thermal treatment process. | 04-12-2012 |
| 20110315673 | SUPPORT STRUCTURE FOR HEATING ELEMENT COIL - Spacer for a vertical support structure of a heating element coil includes a mating feature including complimentary components on first opposing sides of the spacer, a cavity, open to second opposing sides of the spacer, and an extension offset from an axis intersecting the mating features, the extension including a pocket sized to fit an individual loop of the heating element coil. The spacer can be incorporated into a support structure for a heating element coil interlocking adjacent loops of the coil so that they are retained in a collinear and concentric arrangement while allowing the loops of the coil to move freely inward and outward from the central axis in unison. | 12-29-2011 |
