The adjustable support is then jammed to rigidify or fix the shape thereby effectively supporting the preformed mold. The adjustable support is changed from an adjustable state to a support state preferably by applying a vacuum pressure to the aggregate material. In the adjustable state an airflow can be introduced to the aggregate material to allow movement and/or displacement of the material. | 06-26-2014 |
20140220171 | APPARATI FOR FABRICATING THIN SEMICONDUCTOR BODIES FROM MOLTEN MATERIAL - A pressure differential can be applied across a mold sheet and a semiconductor (e.g. silicon) wafer (e.g. for solar cell) is formed thereon. Relaxation of the pressure differential can allow release of the wafer. The mold sheet may be cooler than the melt. Heat is extracted through the thickness of the forming wafer. The temperature of the solidifying body is substantially uniform across its width, resulting in low stresses and dislocation density and higher crystallographic quality. The mold sheet can allow flow of gas through it. The melt can be introduced to the sheet by: full area contact with the top of a melt; traversing a partial area contact of melt with the mold sheet, whether horizontal or vertical, or in between; and by dipping the mold into a melt. The grain size can be controlled by many means. | 08-07-2014 |

A portion of the tube heater is positioned in a second plenum which is pressurized during heating. Air is moved from the second plenum through the heater tube and is directed against a work piece supported on the table. | 09-18-2014 |
