Binder System For Ceramic Arc Discharge Lamp

US Patent:
6592695, Jul 15, 2003
Filed:
Nov 16, 2000
Appl. No.:
09/714635
Inventors:
Daniel L. Polis - Cleveland Heights OH
David Dudik - North Olmsted OH
Vishal Gauri - Lyndhurst OH
Assignee:
General Electric Company - Schenectady NY
International Classification:
B32B 3126
US Classification:
156 8911, 156 8923, 264632, 264670
Abstract:
A binder system for forming a ceramic body, such as a translucent arc tube for a metal halide lamp, comprises a hydrocarbon, such as a paraffin wax, a copolymer, such as poly (ethylene-co-vinyl acetate), and optionally a surfactant. The binder system is mixed with a ceramic powder and heated to above the melting point of the binder. The heated mixture is formed into a compact having the general shape of the finished ceramic body and then cooled or allowed to cool. The hydrocarbon and copolymer have overlapping freezing points so that when the shaped compact cools, crystalline segments of the copolymer (such as ethylene segments) co-crystallize with the hydrocarbon, while amorphous segments (such as vinyl acetate) form bridges between the crystalline regions. As a result, the cooled compact has improved green strength over conventional binder systems.

Discharge Lamp With Vented Reflector

US Patent:
6759794, Jul 6, 2004
Filed:
Apr 27, 2001
Appl. No.:
09/844133
Inventors:
Carolyn Wilson - University Heights OH
Daniel Polis - Cleveland Heights OH
Matthew A. Bugenske - Cleveland Heights OH
Assignee:
General Electric Company - Schenectady NY
International Classification:
H01J 516
US Classification:
313113, 313 22, 313 24, 313 25, 313 12, 362294, 362373, 362264
Abstract:
A high intensity discharge lamp assembly ( ) has improved thermal venting. The discharge light source ( ) is housed within a reflector body ( ). Recesses ( ) are circumferentially spaced around an open end ( ) of the reflector body. A containment structure ( รข) provides a structure that serves the containment function without interfering with the thermal venting.

Suspension Adhesive And Method For Bonding And Sealing Components

US Patent:
2002006, Jun 6, 2002
Filed:
Dec 1, 2000
Appl. No.:
09/728722
Inventors:
Daniel Polis - Cleveland Heights OH, US
Vishal Gauri - Lyndhurst OH, US
Assignee:
GENERAL ELECTRIC COMPANY
International Classification:
C03B029/00
US Classification:
156/089150, 428/484000, 156/332000, 156/325000
Abstract:
A suspension adhesive comprised of a matrix material and a particulate filler material is useful for bonding, sealing, repairing, and modifying ceramic, glass, and powdered metal components. A method for making the suspension adhesive includes the selection of a filler material and a volume percentage of the filler material. Additionally, a matrix material is selected and the filler material is dispersed throughout the matrix material. The suspension adhesive is used to bond and seal components to form, for example, an arc tube for a light source.

Method For Forming Complex Ceramic Shapes

US Patent:
2004016, Sep 2, 2004
Filed:
Apr 12, 2004
Appl. No.:
10/451054
Inventors:
Curtis Scott - Mentor OH, US
Douglas Seredich - Montville OH, US
Daniel Polis - Takoma Park MD, US
Vishal Gauri - San Jose CA, US
Karthik Sivaraman - Mayfield Village OH, US
International Classification:
C03B008/00
US Classification:
065/017200, 445/022000, 445/026000
Abstract:
A method for forming single element arc tubes is provided. The method includes the use of the lost foam process in combination with ceramic forming processes. First, a polymeric material () is formed to define the internal dimensions. The outer dimensions are established with an external mold (), followed by filling the mold with a suspension () that hardens. The outer mold is removed and the part is debindered to melt and remove the inner foam shape, followed by sintering to form a substantially transparent ceramic arc tube ().
