  • Patent number: 9879440
    Abstract: Poles of this invention have an annular body with a wall structure comprising a number of fiber reinforced resin layers, which can be positioned to form an inside and/or outside portion of the wall structure. A portion of the layers are oriented longitudinally within the wall structure, and the wall structure also includes radially-oriented fiber reinforced resin layers. The pole includes one or more layers or a core of a composite material or polymer mortar disposed within one or more locations of the wall structure, e.g., as an intermediate layer and/or as part of the wall inside and/or outside portion. The pole can include an outside surface resistant to ultra violet radiation. Poles of this invention can be formed using a continuous process on a rotating mandrel, making use of differently positioned stations to form the different portions of the pole as the fabrication is moved axially along the mandrel.

  • Publication number: 20080289939
    Abstract: An actuator mechanism for activating a power switch fixedly attached to a wall is provided. The actuator mechanism includes a remote power switch that is portably locatable on the wall separate from the power switch that is fixedly attached to the wall. The remote power switch is operable to be toggled to a first power state and a second power state. The actuator mechanism further includes an extension arm that extends from the power switch in a substantially horizontal direction. Responsive to a user toggling the remote power switch from the first power state to the second power state, the extension arm rotates to activate or deactivate the power switch fixedly attached to the wall.

  • Patent number: 7118629
    Abstract: A device adapted to dispense or spray a coating such as a foam in a predetermined pattern or manner on a substrate, preferably a roof. The spray coating apparatus comprises a spray assembly having a carriage which is operatively mounted on a track that preferably provides a linear travel path. The carriage is controlled by a drive mechanism which causes reciprocating movement of the carriage. A spray gun is mounted on a holder of the carriage and controlled by an actuator and is used to uniformly apply coatings at a predetermined thickness controlled in part by a spray rate on the intended substrate. In one embodiment, the apparatus includes a cart which is either motorized or manual. The apparatus is lightweight and easily disassembled into sections in order to transport the device from a ground surface to a roof.

  • Patent number: 5941485
    Abstract: A step mounting assembly adapted for demountably securing a removable step member to a hollow utility pole. The step mounting assembly utilizes a backing plate having an obverse and a reverse face. An aperture penetrates the backing plate to receive the shank portion of a mounting bolt with the head thereof disposed in opposition to the obverse face of the mounting plate. A projection extends outwardly from the reverse face of the unique backing late at least partially to circumscribe the aperture that penetrates the backing plate. A spacer lug extends outwardly from the obverse face of the backing plate, the spacer lug being located in proximity to the aforesaid aperture. A washer is interposed between the bolt head and the spacer lug. An elongated bar nut is adapted to engage the threaded shank on the mounting bolt while the bar nut is captured within the projection disposed on the reverse side of the unique backing plate.

  • Patent number: 4942897
    Abstract: The remote control and remote handling accessory is of such design that an xchange part (7) contains all elements subject to wear of the accessory, while the anti-wear elements, in particular the accessory case (2) remain firmly connected to the pipeline (1). The exchange part (7) and the accessory case (2) are mutually fixed by a clamping bracket (9). The exchange part (7) comprises a central bolt (16) which is displaceable with respect to the other components of the exchange part (7) and is supported in both axial directions by the clamping bracket (9) which is adapted to be swung open. In this manner the exchange part can be pressed into and pulled out of the anti-wear part (accessory case 2). The other components of the exchange part (7) are connected to a cover (15) with respect to which the central bolt (16) is rotatable, the cover (15) being secured to a slide shoe (8) of a stationary guide rail (4).
