| 20120039814 | Topical Compositions and Methods of Detection and Treatment - A topical composition includes a nanoemulsion of a plurality of hydrophobic particles having a hydrophilic coating therein. The hydrophobic particles are derived from the same or different hydrophobic material and each hydrophobic particle has a melting point below the melting point of the respective hydrophobic material. The nanoemulsion further includes one or more pharmaceutically active agents and/or one or more chemiluminescent disease-detecting systems. | 02-16-2012 |

| 20080222972 | TRUSS GUSSET PLATE AND ANCHOR SAFETY SYSTEM - A peak gusset for securing a safety line for a workman, a roof truss and an anchoring system incorporating the same. The gusset is a substantially planar plate including an attachment region, a coplanar anchor portion and bendable flaps. A plurality of teeth extends from the attachment region and into the side of a truss member adjacent the peak. The anchor portion extends laterally beyond the peak and a hole defined therein receives the security line. The hole is disposed above an upper surface of the truss member and vertically beneath the peak. The gusset is non-removable and does not need to be cut down before a ventilation cap is applied thereover. A pair of peak gussets can be secured on either side of a truss and a connector member for attachment of the security line can extend between peak gussets on adjacent trusses. | 09-18-2008 |
| 20090249740 | ROOFING SHINGLE SUPPORT SYSTEM - A support system for conveniently staging and accessing roofing materials above and across each side of a roof, said system comprising a pair of longitudinally-extending base members, the base members each having a generally triangular-shaped radial cross section; and means for joining the base members to each other. | 10-08-2009 |
| 20090272064 | TRUSS GUSSET PLATE AND ANCHOR SAFETY SYSTEM - A gusset connector plate for anchoring a safety line to a roof truss, a roof truss and an anchoring system incorporating the same. The plate is substantially planar and includes an attachment region and an anchor portion. Teeth extend from the attachment region and into the sides of truss members that form the peak of the roof truss. The anchor portion extends laterally beneath the peak and a hole defined therein receives the connector for the security line. The hole is disposed below the lower surfaces of the truss members and vertically beneath the peak. The plate is permanently engaged with the truss. A single plate or a pair of plates may be incorporated in the roof truss and utilized in the anchoring system. | 11-05-2009 |
| 20100200330 | TRUSS GUSSET PLATE AND ANCHOR SAFETY SYSTEM - A gusset plate for securing roof truss members together and aiding in anchoring a security line. The plate is planar and metallic having front and rear surfaces and an outer perimeter. Teeth project outwardly from the rear surface. The perimeter includes a flat or V-shaped first edge and a U-shaped second edge. The V-shape and U-shape open in the same direction. The plate includes first and second wings defined between the first and second edges and extending for a distance along the front surfaces of the truss members. A shackle on the security line is secured to the roof truss proximate where the roof truss is reinforced by the gusset plate. The plate secures the truss members together and can provide a strong, rigid surface for the shackle to engage thereby reducing the likelihood of damage to the truss when force is applied to the security line. | 08-12-2010 |

| 20100223735 | ROOFING TOOL - A roofing tool comprises a handle with a longitudinal axis and a longitudinal shaft coaxial therewith, the handle having a first end and a second end, a hollow shaft having a first end and a second end, the first end of the hollow shaft being axially inserted into the second end of the handle and the second end of the hollow shaft extending therefrom, a bracket attached to the second end of the hollow shaft, a roller rotatably attached to the bracket, a seam tester member having a tapered pick end and an elongated shaft disposed within the hollow shaft; and a detent member secured to the handle and configured to detain the seam tester member within the handle. | 09-09-2010 |
| 20110088170 | MAGNETIC ROOFING HATCHET - A hatchet head for a roofing tool includes a hammering end having a striking face and a first bore formed in the striking face. The hatchet head also comprises a magnet assembly disposed within the first bore, where the magnet assembly includes a magnet and a cover having a uniform diameter along its length. The cover is configured to retain the magnet within the first bore. Additionally, the hatchet head includes a multi-purpose end having a thickness and an elongated slot extends through the thickness. A gauging assembly is disposed through the elongated slot. | 04-21-2011 |

| 20100215424 | LOCKING DEVICE WITH A SHAPE MEMORY ALLOY ACTUATOR AND METHOD OF USE - A locking device includes a shape memory alloy actuator that engages a locking pin to release the pin and unlock the device it is engaging. Upon heating the shape memory alloy member, it returns to a predetermined shape, which has a length shorter than its non-heated length. As the shape memory alloy actuator shortens, it pulls the locking pin at least a pre-determined distance to release the locking pin from engagement with the device it is locking and into engagement with a pin release member. The pin release member holds the locking pin in the unlocked position until the pin release member is moved from engagement with the locking pin. Once moved, the pin release member disengages from the locking pin and the pin is moved back into its original, locked position. The shape memory alloy actuator and pin release member are also returned to their original position. | 08-26-2010 |
