| 20110140604 | HAND HELD, HIGH POWER UV LAMP - A UV curing lamp has variable resistive ballast provided by at least one resistance alloy wire and a set of switches tapping varying positions along the resistance alloy wire. The variable resistance ballast defines the lamp's maximum operating power consistent with the power supply. The wire in combination with a fan also doubles as thermal ballast provided by air flowing across the wire onto the UV lamp. A detachable reflector in a generally parabolic cylinder shape directs light from the lamp located on the reflector's focal axis. The curing lamp with resistive ballast can be in the form of a handheld unit or as a floor unit with rotating lamps within the housing. | 06-16-2011 |
| 20100209621 | MACHINE AND METHOD FOR RAPID APPLICATION AND CURING OF THIN ULTRAVIOLET LIGHT CURABLE COATINGS - A moveable machine to rapidly apply and cure thin layers of a UV curable coating on a surface such as a floor. The machine has an applicator to apply a thin curable coating in a path following the direction of motion of the machine. The machine also has UV lamps to cure the curable coating with a curing beam that overlaps newly applied coating. The UV lamps emit an intense UV radiation beam creating an annular cure zone around the applicator path. Movement of the machine along with the ensuing movement of the applicator and rotating UV lamps causes the applied curable coating to be exposed to the annular cure zone and cured. This rapid curing of applicator coating paths allows the machine to be immediately passed over the cured area multiple times and rapidly build up multiple thin cured layers to achieve a thick coating. | 08-19-2010 |
