The present invention relates to a system and method for cutting and manipulating the used wind turbine blades for disposal.

During an assembly process for an aircraft, segments of the fuselage are fabricated separately prior to joining the segments together to form the complete fuselage. In order to ensure that abutting ends of the segments mate together correctly, a machining process is performed along the edges of the segments at their ends. One embodiment comprises a trim-tool assembly for machining proximate to an edge of a workpiece. The trim-tool assembly includes an indexing cart configured to mount to a track secured to a surface of the workpiece, where a setting on the indexing cart varies a distance between a centerline of the track and the edge of the workpiece. The trim-tool assembly further includes a tool cart configured to mount to and translate along the track, where the tool cart includes a process tool that performs a machining process on the workpiece at a fixed distance from the centerline of the track.

An apparatus and method for removing the tops of trees, the apparatus including a rotatable first boom configured for coupling to and extending vertically downward from an aircraft and a cutting assembly hingedly coupled to a bottom end portion of the first boom. The cutting assembly includes a housing containing a motor, the housing having an upper portion coupled to the bottom end portion of the first boom. A second boom extends from a lower portion of the housing and supports thereon a singular circular saw which is operatively coupled to the motor. The second boom is arranged at an angle of about 30° to about 55° relative to the first boom. This accomplished by including bend within the housing.

A blade housing includes: a rotary blade and an opening, in which the blade housing is configured to be affixed to a blade housing connector, and in which when a motor rotates the blade housing connector, the rotary blade rotates to cut a post-tension (PT) tendon tail inside a stressing pocket, in which the blade housing is sized to fit within the stressing pocket, in which the opening of the blade housing is sized to allow the PT tendon tail to be extended through the blade housing.

An apparatus for cutting and driving a shaft which extends from a hub, the apparatus incorporating a hub adapter fitted to receive the hub; a plurality of set screws mounted upon the hub adapter for clamping the adapter upon the hub; a half of a releasable fastener attached to the hub; a pair of adapters which are fitted for alternatively receiving the hub adapter; a pair of second halves of the releasable fastener which are adapted for alternatively completing the releasable fastener, wherein each of the second halves of the releasable fastener is connected to one of the adapters among the pair of adapters; a pivoting rotary saw connected to one of the adapters among the pair of adapters; and a shaft driver tool connected to the other of the adapters among the pair of adapters.

The invention proposes a tipped circular saw blade (10) comprising a saw body (11) with a peripheral circular region made of a first material, the peripheral circular region having a plurality of slots (12), and a plurality of tips (13) made of a second material, each tip (13) fixed to a respective slot (12) to form a saw tooth (14) defined between an anterior gullet (15) and a posterior gullet (16), each saw tooth (14) having a cutting edge (141). In accordance with the invention, each saw tooth (14) has a leading face (142) defined between the anterior gullet (15) and the cutting edge (141), the leading face (142) having a profile that includes a single curved surface formed by an R radius, the curved surface encompassing the first material and the second material. The invention further proposes a method of manufacturing a tipped circular saw blade (10), the method comprising a step of forming a saw body (11) with a peripheral circular region made of a first material, the peripheral circular region having a plurality of slots (12); a step of joining a plurality of prefabricated tips (13a), made of a second material, to the respective slots (12) of the peripheral region of the saw body (11), obtaining a preliminary tipped circular saw blade (10a); and a step of grinding the preliminary tipped circular saw blade (10a) to form a plurality of saw teeth (14), each saw tooth (14) defined between an anterior gullet (15) and a posterior gullet (16), and having a cutting edge (141) and a leading face (142) defined between the anterior gullet (15) and the cutting edge (141), the leading face (142) having a profile that includes a single curved surface formed by an R radius, the curved surface encompassing the first material and the second material.

A concrete saw is disclosed and includes a frame having a platform and a leg pivotably coupled to the platform at a pivot axis, at least two rear wheels coupled to the platform at the pivot axis, at least one rear wheel coupled to an end of the leg distanced from the pivot axis, a power and drive assembly disposed on the platform, wherein the power and drive assembly includes an electric motor and a battery pack coupled to the electric motor to provide direct current power to the electric motor, and a cutting assembly driven by the power and drive assembly to cut a groove in a work surface as the concrete saw is moved across the work surface.

An exemplary embodiment of the present invention provides an apparatus for dismantling for heavy water reactor facilities, including: a cutting device configured to divide a calandria of the heavy water reactor facilities into a main shell and a sub-shell; and a transfer device configured to draw the main shell cut by the cutting device to the outside, wherein the transfer device includes a fixing unit configured to fix the calandria; and a transfer unit configured to transfer the fixing unit.

Embodiments include a vehicle side washer assembly, a shaft assembly, and horizontal cloth brush panels. The side washer assembly includes a retractable angled primary arm, a retractable secondary arm, a shaft assembly having an upright shaft, and horizontal cloth brush panels. The upright shaft is disposed through a shaft attachment region of each of the horizontal cloth brush panels. The shaft assembly includes an upright shaft including notches and protrusions, and retrofit discs each including a shaft opening that matches contours of the upright shaft. Each of the retrofit discs includes rotary notches. The horizontal cloth brush panels each include flat fingers, a contiguous central region, and a brush shaft opening cut to match contours of the upright shaft. The horizontal cloth brush panels rotate in a reverse rotation with a direction of travel of a vehicle, and can be mixed and matches with various sizes and shapes.
