US Patent:
20050115493, Jun 2, 2005
Filed:
Sep 24, 2004
Appl. No.:
10/949236
Inventors:
Olexy Radkevich - Schaumburg IL, US
Dennis Persyk - Barrington IL, US
Volodimir Protsenko - Hoffman Estates IL, US
International Classification:
C30B035/00
C30B001/00
C30B015/00
C30B021/06
C30B027/02
C30B028/10
C30B030/04
US Classification:
117200000
Abstract:
An apparatus for growing crystals includes a sealed chamber having a crucible assembly and a seed holder disposed therein. The crucible assembly is adapted to contain a melt therein and the seed holder is selectively positionable within the chamber from a first position relative to the crucible assembly to at least one subsequent position within the crucible assembly. A heater is configured and dimensioned to heat the melt disposed within the crucible assembly and an insulator is included for insulating the heater and the crucible. An actuator rotates at least one of the crucible assembly and the seed holder relative to the other and a support ring suspends the crucible assembly within the sealed chamber. A ceramic thermal shield is disposed atop the support ring and regulates the heat loss from the crucible assembly to an upper portion of the chamber.

US Patent:
20080190358, Aug 14, 2008
Filed:
Feb 13, 2007
Appl. No.:
11/705648
Inventors:
Olexy V. Radkevich - Schaumburg IL, US
Volodimir Protsenko - Hoffman Estates IL, US
International Classification:
C30B 35/00
B23P 11/00
US Classification:
117208, 117200, 117204, 2952501
Abstract:
A seed crystal holder for growing single crystals, such as for use in scintillation detectors for nuclear medicine. The holder includes a cooling shaft, a fastener attached to the cooling shaft, and a gasket for separating the cooling shaft from the seed crystal. The gasket is made of a heat-transferable material such as steel wool or metallic foil to conduct heat from the seed crystal to the cooling shaft, while also providing a cushioning effect to cushion the seed crystal against potentially damaging motion forces.
