  • Aircraft brake wheel heat shield
    Patent number: 7255208
    Abstract: A perforated heat shield (20) is formed of a single layer and is implemented to be positioned between an aircraft brake assembly (34) and wheel assembly (28) in order to effectively protect the wheel assembly (28) and adjacent components from excessive thermal energy generated by an operation of the brake assembly (34) and to promote the cooling of the brake assembly (34) by allowing a partial amount of the thermal energy to radiate to the wheel assembly (28) through apertures (22) provided in the heat shield (20).

  • Silicon ribbon growth wheel and method for heat flow control therein
    Patent number: 4468281
    Abstract: A silicon ribbon growth wheel having a thermal resistance zone between an outer silicon contacting surface and an inner cooling fluid contacting surface to control rate of heat flow from the outer to inner surfaces. In a preferred form the thermal resistance zone is defined by a row of holes through the wheel near the outer surface with said holes isolated from the cooling fluid. A method for controlling the heat flow is also diclosed.

  • Silicon ribbon growth wheel and method for surface temperature profiling thereof
    Patent number: 4468280
    Abstract: A silicon ribbon growth wheel having an internal cooling fluid contacting surface modified to provide a lateral temperature profile on the wheel surface of lower temperature near the wheel edges. In a preferred form the inner surface is provided with grooves near the wheel edges to increase heat conduction to the cooling fluid at the wheel edges. A method for surface temperature profiling the growth wheel is also disclosed. A method for surface temperature profiling the growth wheel is also disclosed.
