  • Patent number: 11863117
    Abstract: A roof mount system supports a solar panel above a roof and includes a base positioned on the roof and a first fastener connected to the base and extending away from the roof and moveable along the base in a direction generally parallel to the roof. A first clamp supports a bottom surface of a solar panel frame and adjusts the height of the solar panel above the roof by moving the first clamp along a first fastener in a direction perpendicular to the roof. A second clamp is connected to a second fastener and moves with respect to the first clamp perpendicular to the roof. The solar panel is clamped between the first clamp and the second clamp portion. A protrusion extends from the first or second clamp to form an electrical bond between the solar panel frame and the respective first or second clamp.

  • Patent number: 11603935
    Abstract: A mechanical seal for sealing against a rotating shaft includes a static ring positioned about the shaft and a movable ring positioned about the shaft and in sliding contact with the static ring. The movable ring is rotatable with the shaft and a tray sleeve is attached to one of the movable ring and the static ring, with the tray sleeve being selectively movable in an axial direction along the shaft. Wear between the static ring and the movable ring causes the tray sleeve to move in the axial direction. The tray sleeve includes an indicator and relative movement of the indicator along the shaft is in proportion to the wear between the static ring and the movable ring.

The top member and the bottom member are operably fixed by a screw set in a symmetric mounting configuration. The contact pad is also made from the rubber material for pressing onto a top cover glass panel near an edge region. The upward rounded end bump is for supporting a portion of a bottom substrate glass panel at a first offset distance away from the top cover glass panel and a horizontal offset distance away from the edge region. The first offset distance is adjusted to a thickness of the frameless solar module and the second distance is predetermined for providing adequate support of the frameless solar module to allow uninhibited flexion under load.

    Abstract: In order to connect a connection piece (10), which is, for example, a pipe coupling or a mounting or a fitting, to a thermally insulated conduit pipe (1), a clamping sleeve (9) with an internal thread (8) is screwed in between the internal pipe (2) of the conduit pipe and the insulation layer (3) of said conduit pipe. A connection body (11) with a plug sleeve (13) is arranged in the internal pipe beforehand. The clamping sleeve (9) acts indirectly on the connection piece (10) by means of a retaining ring (14) in order to press said connection piece against the end face (5) of the internal pipe (2). In this way, the distance between the insulation layer (3) and the casing (4) of the conduit pipe is dispensed with and inaccuracies when cutting the conduit pipe to length can be compensated.
