Appl. No.:

12/409083

Inventors:

Robert Lesko - Franklin NJ, US
Daniel Dayon - Vernon NJ, US

Assignee:

HID Ultraviolet, LLC - Sparta NJ

International Classification:

B05C 9/08

US Classification:

118620, 118641, 118642

Abstract:

Apparatus for curing a photocurable material applied to a floor surface includes a carriage having wheels, a source of curing light carried by the carriage, and a solid state ballast circuit selectively energizing said light source. The apparatus is free of a shutter that would selectively cover the source of curing light.

Filed:

Sep 9, 1996

Appl. No.:

8/709579

Inventors:

Robert J. Lesko - Andover NJ
Shannon K. Lesko - Hackettstown NJ

Assignee:

HID Systems, Inc. - Sparta NJ

International Classification:

B42D 1500
G03G 800

US Classification:

428 401

Abstract:

The present invention relates to a laminated article and a method for making the article. An imageable film is printed on a first side with an image created in a computer. The image can be black and white or color. The imageable film can be transparent or white. The image containing film is then overlaid with a transparent laminate layer to protect the image from weather, abrasion and wear. A colored substrate may be applied on a second side of the imageable film to create a colored sign. The colored substrate may also be used to introduce special effects to the appearance of the finished laminated article.

6/380463

Inventors:

Robert J. Lesko - Newton NJ

Assignee:

HID Systems, Inc. - Sparta NJ

International Classification:

H05B 4122

US Classification:

315263

Abstract:

A high intensity discharge ballast that provides instant restrike of hot high intensity lamps, rapid warm-up and normal ballasting functions so as to circumvent the deficiencies of heating and cooling cycles in high intensity discharge lamps which cycles are unacceptable in special applications such as graphic arts and stadium lighting.

Filed:

Jul 25, 1986

Appl. No.:

6/889368

Inventors:

Robert J. Lesko - Newton NJ

Assignee:

Amergraph Corporation - Sparta NJ

International Classification:

G03B 2720

US Classification:

355 91

Abstract:

A vacuum frame for exposing a light-sensitive sheet to a light pattern according to a negative includes a blanket frame having peripherally bonded thereto a platen and a blanket with the platen being bowable and the blanket being flexible. The platen and blanket are peripherally sealingly bonded to one another, forming a vacuum chamber therebetween. A light transmissive frame mounted to the blanket frame for movement toward and away from the blanket and a spacing and sealing means peripherally interposed between the blanket and the light transmissive frame when the light transmissive frame is moved toward the blanket define an exposure chamber with the blanket. The exposure chamber is adapted to receive a light sensitive sheet and negative. A first vacuum inlet means connects the vacuum chamber to an evacuation means, and a second vacuum inlet means connects the exposure chamber to an evacuation means. A control means evacuates the vacuum chamber to hold the blanket to the platen and evacuates the exposure chamber while said blanket is held to said platen.

Appl. No.:

7/724336

Inventors:

Robert J. Lesko - Newton NJ
Ira J. Pitel - Morristown NJ

Assignee:

Amergraph Corporation - Sparta NJ

International Classification:

G03B 2780

US Classification:

355 83

Abstract:

An exposure system for light sensitive materials held in a vacuum frame includes an electrical light source and a power supply to the light source, the power supply having a power consumption monitor so it can modify the power supplied to the light source to compensate for any fluctuations in power consumption by the light. The light source is supported in a housing having air exhaust openings proximate the mid-portion of the light source. A blower cools the light source with a helical airflow. The voltage drop across the electrical light source is used to control the speed of the blower to maintain the voltage of the light source at a desired level. The housing has an open face and a removable pane. An indicator indicates the presence of the pane. A metal shutter in the housing has a black ceramic surface adjacent the light source to selectively expose light sensitive materials.
