Abstract: A device in which a lifting hopper (82) traverses up along inclined rails (16L) and (16R) and dumps a load into a receptacle of some nature. The lifting hopper (82) will accept a variety of material and debris laden carts, tilt trucks, and wheel barrows. No modifications or special attachments are needed to use the various carts, tilt trucks, and wheel barrows. The loaded cart, tilt truck or wheel barrow positions in the lifting hopper and secures in place. The lifting hopper (82) traverses up along incline rails (16L) and (16R), rotates and dumps, then returns to the original position ready for another cycle. Material or debris may load directly into the lifting hopper (82) without the use of a cart, tilt truck, or wheel barrow when wheel (58) extends the dumping device can reposition around the material or debris receptacle, or loaded onto a truck or trailer and transported to a different site.

Abstract: A tilt and go assembly included as part of a load port interface assembly is disclosed for providing quick and easy attachment and adjustment of the load port interface assembly to a BOLTS interface. When a load port interface assembly according to the present invention is positioned adjacent to a BOLTS interface, the assembly is tilted away from the BOLTS interface, so that a socket in the load port interface assembly may raise upward slightly and be seated on the ball joint. Thereafter, the upper portions of the load port interface assembly may be tilted upward so that the assembly is roughly parallel and adjacent to the BOLTS interface. Once the load port interface assembly is seated on the ball joint of the BOLTS interface, the vertical and lateral positions of the load port interface assembly may be adjusted as desired with respect to the BOLTS interface.

The present debris removal system includes a tilting dumpster or bucket which is mechanically coupled to the carriage device and is transportable from ground level to the roof under construction for carrying debris and other materials. The present system includes a detachable chute device which is attached at the base of hoist to receive debris from the dumpster which is conducted by gravity to a dump truck for disposal. The present system also includes an automatic release mechanism for dumping the contents of the bucket as it contacts the chute at the lowermost position of its travel.

Abstract: The present invention relates to a mobile concrete mixing system which substantially comprises: a feeding unit (2); a mixing unit (3); a conveyor belt; and a support structure (5) that embodies a first framework (18) supporting the conveyor belt (4), and a second framework (19) supporting the mixing unit (3). According to the present invention, the first (18) and second (19) frameworks are connected to each other by means of a hinge (22) which allows for the rotation of the first framework (18) about a substantially horizontal axis (X) in relation to the second framework (19). In this manner, a movement of the mixing unit (3) between a transporting position (23) and an operative position (24) is determined. Such a rotation about the axis (X) is obtained by keeping the mixing unit (3) in a horizontal position.

Abstract: A carbonaceous heat source comprising metal oxides and methods for making such heat source are provided. The heat source has an ignition temperature substantially lower than conventional carbonaceous heat sources, while at the same time produces virtually no carbon monoxide upon combustion. The heat source is prepared by pre-forming the carbon and binder materials into a desired shape, and then treating the shape with a sol containing metal oxide precursors. The metal oxide precursors are deposited in the pre-formed carbon shape. Further treatment converts the deposited metal oxide precursors into metal oxide.

Abstract: A pipe pick-up and laydown machine for lifting a joint of pipe from a generally horizontal position on a pipe rack to an inclined and elevated position relative to an elevated rig floor for connection to rig elevators by the drilling crew. The apparatus includes a horizontal base position adjacent the pipe racks with a pipe carrying trough slidably mounted in a trough trestle which can telescope in and out of one end of the trestle. An inclined track extends from one end of the base to a position near the edge of the rig floor and structure is provided for lifting the front end of the trough trestle along the inclined track. The rear end of the trough trestle is mounted on a sliding articulating arm which first moves forward as the front end of the trough trestle is elevated on the inclined track and then stops and pivots to raise the rear end of the trestle to incline the pipe carrying trough at a desired elevation when extended over one edge of the rig floor. The operation is reversed when laying down pipe.

Abstract: A bucket conveyor is provided with a frame having upwardly inclined spaced parallel guide rails which support the bucket for up and down movement along the inclined guide rails, a chain-and-sprocket bucket support and drive mechanism is disposed along each side of the conveyor frame with the bucket being secured to the chains for movement therewith so that when the bucket is brought to the upper most end portion it will rotate around the sprocket at that location and thus dump the contents of the bucket. An alternative embodiment utilizes a bucket with a hinged bottom which falls away as the bucket reaches the top of the conveyor.

Abstract: A pipe-conveying catwalk has a ramp affixed to the floor of a drilling rig and a main frame ground supported adjacent to a pipe rack so that pipe can be conveyed between the rack and the derrick floor. Pipe is rolled from the rack into a trough which forms part of a stinger. The stinger is nested within a boom and can be telescoped to extend longitudinally away from the boom. The boom is retracted into nested position within the main framework. One end of the boom is attached to the main frame by an extensible swing arm apparatus which elevates the outer end of the boom while the other end of the main frame is attached to the rig floor by a ramp which moves the other end of the boom from the nested position vertically upwards and towards the rig floor. A pipe is rolled from the pipe rack into the trough, the boom is elevated into an inclined position such that the stinger telescopes from the boom to position the box end of the pipe in overlying relationship respective to the derrick floor.
