20100307407 | ROLLER APPLICATOR - A roller applicator for applying a coating to a surface selectively engages roller covers of varying tolerances, and releases a roller cover by actuation of an ejector. The roller applicator includes a frame. A roller cover support member, a securing member and an ejector are mounted on the frame. The securing member is formed with fingers that expand radially upon longitudinal movement of the securing member along an actuator to apply pressure to the inner surface of a roller cover and engage the roller cover. The ejector collapses the fingers to release the pressure on the inner surface of the roller cover and disengage the roller cover. | 12-09-2010 |

20100018653 | ADHESIVE TAPE DISPENSER AND APPLICATOR - A one handed reusable tape dispenser and applicator comprises side walls, a top wall and a separate bottom wall which may be opened to allow loading of a roll of tape through an open front. Further, the tape dispenser is provided with tabs, a button and a pressing bar which present a leading length of tape in an arched condition across its width extending forwardly from the dispenser ready to be applied to a substrate; and an enlarged pressing surface allowing a user to easily dispense tape onto substrates such as wrapping paper. | 01-28-2010 |

20130088890 | EDGE-LIT LUMINAIRE - An edge lit luminaire includes a light source. A housing has an interior cavity for receiving the light source. The housing includes a heat sink for directing heat away from the light source. At least one optional end cap is secured to an end of the housing that covers the cavity. A lightguide is secured inside the housing and has an edge located in proximity to the light source. At least one of a reflector and a lens (e.g., lens optic) directs light from the light source to the edge of the lightguide. The lightguide includes a light extraction surface enabling light to be transmitted from the lightguide. The housing can also feature a channel and slot for mounting the luminaire to a support surface. The lens optic can be designed to have specific dimensions that facilitate efficient design and operation of the luminaire. | 04-11-2013 |
20140160755 | TROFFER LUMINAIRE SYSTEM HAVING TOTAL INTERNAL REFLECTION LENS - A system and method for efficiently transmitting and distributing light emitted from a light source such that substantially all of the light is directed into an area to be illuminated. The system provides a troffer luminaire including one or more high efficiency optical lenses having total internal reflection (TIR) such that substantially all the light collected from a light source passes through the lenses with good luminance uniformity. The lenses are flexibly configurable to control the distribution profile of the light output through the lenses as desired for particular lighting applications. In one or more embodiments, other devices and techniques including diffusers, reflectors, spacing, and the like may be used to further control the distribution profile of the light output through the lenses. | 06-12-2014 |

20090309245 | WET SCRUBBER TRAY - An improved wet scrubber tray provides increased resistance to vibration-induced cracking. The tray is self supporting to eliminate wastage of raw material, and additional internal stiffeners added to the tray make multiple intermediate stiffeners. The connection of the intermediate stiffeners to the perforated bottom plate is changed to eliminate the shop weld in the bottom plate. The holes in the perforated bottom plate are repositioned so that they are moved away from the boundaries of the tray to reduce their influence on boundary conditions. The thickness of the tray material may be increased to lower the vibratory stresses. The mechanism for holding the trays themselves within the spray absorber tower is changed so that the trays are now held down by plate material that is attached to the support grid, but not to the trays. Three field welds are applied to the sides of each tray to hold the trays in place relative to each other and are strategically placed to allow adjacent side stiffeners to act together as a composite section, thus increasing their strength. Elastomeric material such as neoprene is used at the tray-to-grid attachments to increase the damping of the system. Formed features in the trays such as single or multiple ribs, bosses, domes or dimples may also be provided to increase tray stiffness or influence wet scrubber performance. | 12-17-2009 |
