Corona Charging Device And Methods

View page
US Patent:
7130178, Oct 31, 2006
Filed:
Mar 11, 2003
Appl. No.:
10/386252
Inventors:
Timothy Allen Pletcher - Easthampton NJ, US
David Keller - Newtown PA, US
Wen Ho - Plainsboro NJ, US
Eugene Samuel Poliniak - Willingboro NJ, US
John Paul Furda - Hamilton NJ, US
John Thomas McGinn - Flemington NJ, US
Donald Chester Pultorak - Trenton NJ, US
Mortaza Kashef - Trenton NJ, US
Assignee:
Sarnoff Corporation - Princeton NJ
International Classification:
H01T 23/00
US Classification:
361226, 361230
Abstract:
The invention is directed to a corona charging device having a powder feed with an outlet. The device has an internal charging cavity having an inlet and a charged powder outlet. The powder feed outlet is positioned at the internal charging cavity inlet. The device is adapted to guide a powder stream downstream from the powder feed outlet to the charged powder outlet. The device also includes a corona charger having one or more needle projections (each having a tip) positioned and adapted to facilitate a corona ion flow from the needle projections and intersecting the powder stream. The device also includes a rotating ground electrode adapted to be charged or grounded to attract the corona flow from the needle projections, and to rotate segments of the ground electrode between the internal charging cavity and a ground electrode cleaner.

Apparatus And Method For Cleaning Shadow Masks In Color Picture Tubes

View page
US Patent:
43613705, Nov 30, 1982
Filed:
Sep 30, 1980
Appl. No.:
6/192365
Inventors:
Karl G. Hernqvist - Princeton NJ
Donald C. Pultorak - Trenton NJ
Assignee:
RCA Corporation - New York NY
International Classification:
H01J 900
US Classification:
316 2
Abstract:
The present invention provides an improvement in shadow mask type color picture tubes. The improvement comprises a ferromagnetic member located within a tube and means for holding the ferromagnetic member within the tube. The invention also encompasses a method of utilizing the ferromagnetic member to remove particles from a shadow mask of a color picture tube. The method includes the use of a magnet to release the ferromagnetic member from the holding means and to move the ferromagnetic member over a surface of the shadow mask.

Modular Electron Gun For A Cathode-Ray Tube And Method Of Making Same

View page
US Patent:
47206543, Jan 19, 1988
Filed:
Nov 26, 1986
Appl. No.:
6/935390
Inventors:
Karl G. Hernqvist - Princeton NJ
Donald C. Pultorak - Hamilton NJ
Assignee:
RCA Corporation - Princeton NJ
International Classification:
H01J 2950
US Classification:
313414
Abstract:
A novel electron gun for a cathode-ray tube includes at least one and preferably three cathode assemblies and at least four successive electrodes longitudinally spaced from the cathode assemblies. Each of the electrodes has at least one and preferably three electron beam apertures therethrough. The cathode assemblies and two of the electrodes are attached to a ceramic support member which is the sole supporting interconnection therebetween. A third electrode of the four successive electrodes has a distal electrode member and a proximal electrode member. The proximal member also is attached to the ceramic support member to form a first gun module. A second gun module includes a fourth electrode of the four successive electrodes which is in spaced relation to the distal member of the third electrode. The fourth electrode and the distal member of the third electrode are interconnected by a pair of insulative spacers. The second gun module is secured to the first gun module by fixedly attaching the distal member of the second gun module to the proximal member of the first gun module.
