The target automatically resets to the at least one firing position.

Abstract: A modular target structure is disclosed for supporting targets during target practice. An example modular target structure includes a first leg structure, a second leg structure, and an interconnecting member. The interconnecting member connects between the first leg structure and the second leg structure to form a substantially triangular shaped support structure which can be utilized in a horizontal or vertical configuration. At least one target mount may be provided for attaching targets. The support structure is readily assembled and unassembled and can be configured between an operating position for target practice, and a collapsed position for transport and storage.

Abstract: A process of fiberglass recycling, such as for windmill blades or other feedstock having a fiberglass component. An example of the process includes cutting a feedstock having a fiberglass component. After cutting the feedstock, it is fed into a controlled kiln for pyrolyzing. Pyrolysis is at a temperature of about 550-650 degrees Celsius to completely remove all resins, epoxies, and other non-fiberglass components from the feedstock to produce a fiberglass end-product.

Abstract: An example telecommunications pole topper includes an axisymmetric centerline support structure configured for mounting at least one telecommunications antenna. A shroud closes off an interior voided area formed between the shroud and the centerline support structure. A universal multiple-axis adjustable bracket is configured to move up and down and around the centerline support structure when mounted thereto. The multiple-axis adjustable bracket together with the centerline support structure provides a mounting structure within the interior voided section of the shroud for mounting the at least one telecommunications antenna to the centerline support structure for 360 degrees of rotation about the centerline support structure. The support structure within the shroud accommodates different antenna sizes and shapes of telecommunications antennas and different mounting configurations to support a plurality of telecommunications coverage patterns.

Abstract: An equipment tower includes a foundation, a cast-in-place concrete plinth extending vertically from the foundation, and a tower portion extending vertically from the plinth. The equipment tower is constructed at a site having a set of tower specific parameters, and at least one dimension of the plinth is selected based on a tower specific parameter. For example, a height of the plinth may be selected to achieve a desired elevation of the topmost surface of the plinth, so that two towers having identical tower segments will have a common equipment height in spite of variations in their respective foundation elevations due to variations in local ground level. Moreover, the cast-in-place plinth may be designed to include a door opening large enough to accommodate equipment to be installed within the tower.

Abstract: A system and method for installing a post-tensioning tendon (130) in an equipment tower (100). A sheave frame (196) attaches to anchor rods (140), and a pulley (198) is mounted to the sheave frame through which a hoisting cable (197) is passed for connection to an end (138) of the tendon to lift the tendon to the anchor rods. A carriage assembly (150) having a shank (152) and a bearing plate platform (154) extending transversely from the shank for receiving a bearing plate (170) is attached to the tendon. The carriage assembly includes a deflecting surface (158) to deflect the carriage assembly away from the installed bearing plate upon lowering after tendon attachment. A pair of hydraulic jacks (210) tension the tendon to a desired load.

Abstract: A concrete wind turbine tower segment is provided with a bearing plate formed by a plurality of individual smaller plates secured within the concrete body of the tower segment. The tower segment may include an anchor bar cage assembly made of an embedded plate with a plurality of anchor bars extending there through and through the plates. A protective sleeve may be positioned over the anchor bars. A method of forming the tower segment includes attaching the plate segments to a precision formed template ring as part of the cage assembly, pouring concrete/grout around the cage assembly against the plates, and removing the template ring to reveal a precision mate face of the bearing plate. The single large, expensive ring may be reused to form multiple tower segments.

Abstract: An equipment tower having a ladder formed of a plurality of ladder segments each joined to a respective tower segment by a pivotal connection prior to the tower segments being stacked during erection of the tower. The pivotal connection provides a degree of freedom of movement which facilitates the interconnection of adjoining ends of the ladder segments after stacking of the tower segments. Additional accommodation of as-built spacing of the adjacent ends of the ladder segments may be provided by a connecting segment. The pivotal connection may be a rod inserted through a rung of the ladder and supported by a support assembly attached to the tower segment.
