    摘要： A robotic system having a movable gantry robot (10) for conducting construction operations. The gantry may have an expandable bridge (20) and articulated gantry support legs (34) as well as a support track system (60) holding a gantry robot (800) which may hold one or more implements and peripheral devices (806). The device can be moved by propulsion mechanisms, a controller, and one or more geo-positioned control devices to provide position information for the robotic gantry as it moves back and forth along a plurality of work sites (700). The robotic gantry is connected to a power supply system (236). The controller is automated, self-navigating, and activates, deactivates, and/or changes the operation of the propulsion mechanisms, and deploys, retracts, activates, deactivates, and/or changes the operation of one or more of the construction implements. The height of the frame may be adjusted by extending and rotating risers and booms to accommodate different building heights or sub-level heights at a worksite. A conveyor system is optimized for removing dirt from or delivering material to the robotic arm. This invention can be applied to automating construction jobs including surveying, land preparation, excavation, foundation, masonry, framing, and additive fabrication.

    摘要： This application presents a method and apparatus for cooling a through-ported cutting tool with a source of liquid CO2 with a compressed air line with a compressed air inlet and multiple CO2 injection capillary segments; the capillary segments interconnect to the same source of liquid CO2 and can have high pressure valves and throttles; the throttles have different sizes; a first capillary ends near the cutting tool; the second capillary ends near the compressed air inlet. Using a particular sequence of opening or closing the valves to the liquid CO2 to the capillaries, mixing with the compressed air provides and recycling the residual CO2, this invention provides for uniform and controlled cooling of the cutting tool within a certain temperature range.

    摘要： An electrostatic spray application apparatus and method for producing an electrostatically charged and homogeneous CO2 composite spray mixture containing an additive and simultaneously projecting at a substrate surface. The spray mixture is formed in the space between CO2 and additive mixing nozzles and a substrate surface. The spray mixture is a composite fluid having a variably-controlled aerial and radial spray density comprising pressure- and temperature-regulated propellant gas (compressed air), CO2 particles, and additive particles. There are two or more circumferential and high velocity air streams containing passively charged CO2 particles which are positioned axis-symmetrically and coaxially about an inner and lower velocity injection air stream containing one or more additives to form a spray cluster. The axis-symmetrical CO2 particle-air streams are passively tribocharged during formation, and the spray clustering arrangement creates a significant electrostatic field and Coanda air mass flow between and surrounding the coaxial flow streams.
