| 20090183432 | HOOK AND LOOP WEATHERSTRIPPING SYSTEM - Disclosed is a two part hook and loop weatherstripping system in which one portion, such as the hook portion that is attached to a window frame and another portion such as the loop portion that is attached to the hook portion and includes a flexible material that may be compressible to provide a seal between a window sash and the window frame. The removable portion can be easily removed and cleaned or replaced with a new portion. Different thicknesses of the removable portion of the hook and loop weatherstripping allows various size gaps between a window frame and a sash to be easily filled. The use of two part hook and loop components incorporating a weatherstripping system provides for the components to be utilized in such a way so as to provide an overlap joint at all corners that restricts linear shrinkage and eliminates the holes that commonly materialize at the corners from shrinkage of single part weatherstripping systems. The compressible portion of the weatherstripping can be easily removed using the hook and loop fastener and replaced to provide a weathertight seal. A window screen can also be incorporated in the weatherstripping system to allow easy removal of the window screen for replacement or cleaning. | 07-23-2009 |

| 20110033729 | Tempered plated wire - The present invention is a method of manufacturing plated wire. The method includes drawing a feed stock to form drawn wire, tempering the drawn wire to form tempered wire and plating the tempered wire to form the plated wire. The plated wire exhibits a tensile strength that substantially meets ASTM A229-99. | 02-10-2011 |

| 20110135440 | SYSTEM AND METHOD FOR UNSLEEVING TRAYS - A system for unstrapping and unsleeving a tray is provided. The system comprises a tray-transport configured to transport a tray in the system, a strap cutter configured to cut a strap on the tray, a strap-removal portion configured to remove the strap cut by the strap cutter, and an unsleeving station configured to remove a sleeve from the tray. The unsleeving station is configured to remove the sleeve from the tray after the strap-removal portion removes the cut strap. | 06-09-2011 |

| 20100126826 | Package diverting mechanism for conveyor systems - This invention presents a unique design for a mechanism to be used in conveyors systems to selectively divert or re-direct packages off of the main conveyor and onto a secondary conveyor. This design utilizes a set of discs mounted eccentrically on an axis underneath and perpendicular to the conveying rollers. The discs are positioned edgewise and spaced between the conveying rollers. The rotation of the discs is triggered by the control system to coincide with the presence of the package selected to divert when it is on the conveying surface. The discs are mounted eccentrically in their common axis so when the array of discs is rotated the eccentricity of their rotation makes the edge of the discs extend above the conveying surface to lift the package and change its direction of motion with the tangential speed and direction of the rotating disc(s). A secondary conveyor is positioned next to the main conveyor to receive the package diverted off of the main conveyor. | 05-27-2010 |

| 20090123400 | COMPOSITIONS AND METHODS FOR REDUCING PHOTOSENSITIVITY ASSOCIATED WITH PHOTODYNAMIC THERAPY - The present invention provides compositions and methods for decreasing photosensitivity induced by photodynamic therapy (PDT). The compositions and methods of the present method employ porphyrin complexing molecules as agents for reducing photosensitivity. | 05-14-2009 |
| 20100100083 | METHOD OF TREATMENT FOR DERMATOLOGIC DISORDERS - A method of treating acne using lower light intensity, fewer blue light treatments, and no photodynamic or photosensitizing agents is provided. | 04-22-2010 |
| 20100191172 | ILLUMINATOR FOR PHOTODYNAMIC THERAPY - An apparatus and method for photodynamic therapy or photodynamic diagnosis using an illuminator comprising a plurality of light sources generally conforming to a contoured surface and irradiating the contoured surface with substantially uniform intensity visible light. The light sources may comprise generally U-shaped fluorescent tubes that are driven by electronic ballasts. Adjustment of the ballast voltage controls the output power of the tubes. The tubes are supported by a sheet-metal or plastic housing and are covered by a polycarbonate shield which directs cooling airflow within the unit and prevents glass-patient contact in the vent of tube breakage. An aluminum reflector located behind the tubes increases both the output irradiance and the uniformity of the output distribution. The spacing of the U-shaped tubes is varied to increase the output at the edges of the illuminator to make the output more uniform. Also, different portions of the tubes are cooled at different amounts, to improve uniformity. A light sensor monitors output from the U-shaped tubes to provide a signal for adjusting the output from the tubes. | 07-29-2010 |

| 20090192071 | USE OF PHOTODYNAMIC THERAPY TO ENHANCE TREATMENT WITH IMMUNO-MODULATING AGENTS - Methods of enhancing the efficacy and safety of treatment with immuno-modulating agents are provided. The inventive methods combine treatment with immuno-modulating agents with photodynamic therapy (PDT). PDT can be administered before, during or after administration of the immuno-modulating agent. Combination therapy achieves at least the same efficacy as immuno-modulatory therapy in less time, with less immuno-modulating agent and fewer side-effects. | 07-30-2009 |
