Appl. No.:

10/742704

Inventors:

William G. Gardner - Glendale AZ, US

International Classification:

G01J 1/00
G21F 5/02
H01J 1/62

US Classification:

2505031, 250504 R, 2504981, 313485, 313486

Abstract:

A variable wavelength ultraviolet lamp. An apparatus for selectively producing one or more of a plurality of wavelength distributions of light is provided, comprising a primary light source having a primary wavelength distribution, at least one wavelength-transforming material that, in response to illumination by the primary light source produces secondary light having a wavelength distribution different from the primary light wavelength distribution, the wavelength-transforming material being disposed on a substrate external to the primary light source, and a wavelength-transforming material selection mechanism for placing at least a portion of one or more selected wavelength-transforming materials in front of the primary light source, in a selected preferred direction of light emission from the apparatus, such that the selected wavelength-transforming materials emit from the apparatus light having a wavelength distribution different from the primary light wavelength distribution.

US Classification:

250504R, 25045411, 25045511, 2504931, 2504941, 2505051, 313485, 313486, 355113

Abstract:

This invention provides a small form factor apparatus for selectively producing one or more of a plurality of wavelength distributions of radiation, comprising a UV Light Emitting Diode (LED) as the primary UV LED radiation source and one or more wavelength transforming (WT) materials separated from the primary UV LED radiation source, that in response to irradiation by the primary UV LED radiation source, produce transformed radiation having a wavelength distribution that is different from the wavelength distribution of the primary UV LED radiation source. None, one, or more than one of the various WT materials may be selected by the user, to allow either the primary UV radiation, or the transformed radiation, or both simultaneously, to be to be emitted from the apparatus in a preferred direction.

Appl. No.:

13/769381

Inventors:

William G Gardner - Glendale AZ, US

International Classification:

H01J 1/62
G01N 21/00
A61N 5/06

US Classification:

250504R, 2505031, 25045411, 25045511, 2505051, 250365, 2504931, 313485

Abstract:

This invention provides for a removable/replaceable, wavelength-transforming sleeve/sheath to be placed around a primary UV radiation source that emits a primary UV wavelength spectral distribution; such that at least a portion of the sleeve/sheath transforms at least a portion of the primary UV wavelength spectral distribution to a different secondary wavelength spectral distribution. Additionally, the sleeve/sheath may help to prevent breakage of the primary UV radiation source and to contain the broken pieces in the event of breakage. In some embodiments, a portion of the sleeve/sheath may be coupled with a UV reflective surface to direct radiation in a preferred direction. Individual sleeves/sheaths may have various patterns of wavelength-transforming materials that emit one or more secondary wavelength spectral distributions and the sleeve/sheath may also have one or more sections that allow transmission of the primary UV wavelength spectral distribution.

International Classification:

G01J 3/10

US Classification:

25050400R

Abstract:

An apparatus for selectively producing one or more of a plurality of wavelength distributions of radiation. The apparatus comprises a primary UV radiation source and one or more wavelength transforming materials separated from the primary UV radiation source, that in response to irradiation by the primary UV radiation source, produce transformed radiation having a wavelength distribution that is different from the wavelength distribution of the primary UV radiation source. None, one, or more than one of the various WT materials can be selected by the apparatus, to allow the primary UV radiation, any individual transformed radiation, or any combination of the various radiations to be to be emitted from the apparatus.

Appl. No.:

8/267479

Inventors:

William G. Gardner - Glendale AZ

International Classification:

B43K 500

US Classification:

222129

Abstract:

An applicator for eradicating or removing transparent or translucent emphasizing inks, particularly from a paper surface, wherein the emphasizing ink has been used over permanent ink or a printed surface to emphasize such surface or a writing thereon. The applicator comprises a container, a liquid bleaching or oxidizing agent in the container for the emphasizing ink and means on one end of the container, such as a felt tip, roller, pressurized spray nozzle or hand pump, to apply a thin film of the ink removing agent to the emphasizing ink and to effect the eradication or removal thereof without substantially affecting the underlying ink or printed material which has been emphasized. In another embodiment of the invention, a dispenser of a neutralizing agent is also provided to abate the effects of excess bleaching or neutralizing agents on the surface being treated.
