A sealing apparatus for sealing against an opening in a structure for establishing a sealed passage therethrough, comprising a main body having opposed first and second sides, a first hollowed portion projecting from the first side, a second hollowed portion projecting from the second side and a flange between the first and second hollowed portions, the first and second hollowed portions communicating with one another to define a sealed passage for allowing a cable/pipe to pass therethrough.

The present subject matter provides apparatus for connecting a roof assembly to a membrane using at least one backer rod connected to the membrane, including: counterflashing disposed about the perimeter of the roof assembly, the counterflashing including a plurality of grips configured to receive and engage the at least one backer rod in contact with the membrane, so as to hold the membrane securely in position and maintain a weather seal at a desired flashing height of the membrane. In various examples, the roof assembly includes a roof hatch, window, or other fenestration unit. In various examples, the present subject matter provides a hatch attached to a wall for sealing an opening. In various examples, the present subject matter provides a method for operating a roof assembly for connection to a roof membrane.

A recording head has a near-field transducer that extends a first distance away from a media-facing surface. Two subwavelength focusing mirrors are at an end of a waveguide proximate the media-facing surface and extend a second distance away from the media-facing surface that is less than the first distance. The subwavelength mirrors are on opposite crosstrack sides of the near-field transducer and separated from each other by a crosstrack gap. The subwavelength focusing mirrors each include a first material at the media-facing surface and a plasmonic material that covers an edge of the subwavelength focusing mirror that faces the near-field transducer. The first material is more mechanically robust than the plasmonic material.

A through the hole vent pipe fitting seal includes a generally hollow cylindrical main body having an annular flange extending outwardly thereof perpendicular to the axis of said main body. An annular sealing member is positioned against a lower surface of the annular flange. An annular clamping member is movably attached on the main body to clamp the seal around a hole in a construction material on which the fitting is to be mounted.

A recording head has a near-field transducer proximate a media-facing surface of the recording head. The near-field transducer extends a first distance away from the media-facing surface. A waveguide overlaps and delivers light to the near-field transducer. Two subwavelength focusing mirrors are at an end of the waveguide proximate the media-facing surface. The subwavelength mirrors are on opposite crosstrack sides of the near-field transducer and separated from each other by a crosstrack gap. The subwavelength focusing mirrors each include a first material at the media-facing surface and a liner that covers an edge of the mirror.

The present invention relates generally to the photovoltaic generation of electrical energy. The present invention relates more particularly to photovoltaic arrays for use in photovoltaically generating electrical energy. Aspects of the present invention provide a variety of photovoltaic roofing elements and systems that include, for example, interlocking geometries to provide for water handling and integration with conventional roofing materials; and wire management features that can protect wiring and associated electrical components from physical and/or environmental damage.

The second material includes a plasmonic material, and the first material is more mechanically robust than the second material.

A fire and water resistant, integrated wall and roof expansion joint seal system includes an expansion joint seal for a structure. The seal includes a central portion having an underside and at least one central chamber disposed around a centerline, a first flange portion extending outwardly from the centerline and a second flange portion extending outwardly from the centerline in a direction opposite the first flange portion. The system further includes a joint closure. The joint closure includes a core and a layer of a water resistant material disposed on the core. The joint closure further includes an end portion configured to match and integrate with the underside of the central portion to form the watertight, integrated wall and roof expansion joint seal system. A fire retardant material is included in the core in an amount effective to pass testing mandated by UL 2079, and the core with the fire retardant material therein is configured to facilitate compression of the core when installed between the first substrate and the second substrate by repeatedly expanding and contracting to accommodate movement of the first substrate and the second substrate; and the core with the fire retardant material included therein is configured to pass the testing mandated by UL 2079. Movement of one or both of the first substrate and the second substrate causes a response in the central portion to maintain the seal.

The invention provides a generally horizontal roof deck having a corner and two parapet walls meeting at the corner. A roofing membrane has a major portion adhered to the roof deck and a side portion adhered to the first parapet wall and an end portion adhered to the second parapet wall. A bead of caulk is located between the side portion and the end portion and a respective parapet wall. Termination bars are affixed to the each of the parapet walls by axially driven pins that capture the termination bars on top of the respective side or end portions along their upper edges. Also disclosed is a method for constructing a roof deck using termination bars and axially driven pins that do not require predrilled holes.

An expansion joint having three axes of expansion for roof to wall and roof to roof applications. An expansion joint with roof to wall applications preferably includes a continuous cleat, a curb rail, a condensate seal, a formed cap, a sliding surface plate and a plurality of retainer plates. The continuous cleat slides vertically relative to a wall and horizontally relative to a roof curb. The continuous cleat slides vertically relative to the formed cap. An expansion joint with roof to roof applications preferably a continuous cleat, a formed cap, a curb rail, a Z-curb rail, a condensate seal and a plurality of retainer plates. The continuous cleat slides vertically relative to a fixed curb wall and horizontally in two axes relative to a free roof curb.
