Abstract: An apparatus 10 and method for excavating, transporting, and transplanting a live tree. The invention relates more specifically to equipment, which utilizes curved ground piercing excavation blades 42 moveably supported on a ring assembly 50 that is pivotally supported in a support frame 20. The ring assembly and the support frame may be positioned around the tree and the blades forced into the ground to excavate a root ball which can thereafter be lifted and transported for subsequent transplantation. The ring assembly 50 may be tilted rearward to permit transporting the tree in a rearward inclined or tilted position, such that wind an obstacle damage to the branches and limbs may be reduced as compared to forward tilting movers. In addition, the rearward tilt may accommodate tilting relatively tall trees at angles of up to 90 degrees from vertical, in order to transport the tree under relatively low over-head clearance obstacles, such as bridges, other trees, and porta cocheres.
Abstract: Methods and systems are provided for drilling a well bore 60 through a subterranean formation using a drilling rig 25 and a drill string 50, whereby the bottom hole pressure while circulating drilling fluid (“ECD”) may be substantially maintained when circulation is interrupted or altered, such as when adding a joint of drill pipe to or removing a joint of drill pipe from the drill string. The method includes controllably applying and maintaining a desired variable annulus fluid pressure in the well bore, and thereafter controllably releasing the pressure from the well bore 60. In addition, methods and systems are provided for rotating the drill string while trapping, maintaining and/or releasing the well bore pressure. A substantially constant ECD pressure may be maintained on a formation, thereby facilitating the use of a lower density drilling fluid than may otherwise be required to maintain well control.
Abstract: A computer file update or patch process involves building a Patch File. The existing or original file (the OLD file) and the revised file (the NEW file) are input into a Patch Build program. The differences in the OLD file and the NEW file are determined by the Patch Build program, and this information is output by the Patch Build program as a Patch File. The Patch File is distributed, along with a Patch Apply program, to end users so that the OLD file is efficiently converted to the desired, updated NEW file. The OLD file and the Patch File are input by the end user into the Patch Apply program. The Patch Apply program changes, at the bit level, only the portions of the OLD file required to yield the desired file update. By distributing only the Patch File and Patch Apply program to the end users, the desired file update can be implemented by the end user with maximum operational and economic efficiency.
Abstract: A vertical reinforced concrete wall for a concrete building including a plurality of insulating panel units horizontally spaced from each other each formed of a polystyrene foam material having a rectangular shape. A pair of channel-shaped vertical side members having side flanges and inturned lips on the side flanges are fitted over the side edges of the insulating panel on site with the lips biting into the insulation panel to secure the side members thereon. The plurality of spaced insulating panel units are mounted between a pair of opposed upper and lower channel-shaped track members which extend horizontally to define the upper and lower ends of the vertical wall. The units are spaced from each other a predetermined distance, such as eight (8) inches, to form space for a vertical concrete column between adjacent insulating panel units.
Abstract: Concentric, tubular sections are assembled by first securing annular centralizers and insulation about the external surface of the smaller diameter tube while the tube is horizontally disposed. The larger tube is then vertically aligned and lowered into a recessed area formed below the assembly area work level. A lifting cable, secured at one end to a lifting device, is extended through the smaller diameter tube and attached to a hoisting arrangement that vertically orients the tube concentrically over the larger diameter tube. Spring-loaded legs on the lifting device are manually retracted radially to permit the smaller tube to be lowered concentrically through the larger tube. The inner tube is lowered until the legs spring radially outwardly to engage the base of the larger tube. The entire assembly may then be lifted as a unit by the hoist with the lifting device, establishing the axial positions of the two tubes relative to each other.

Abstract: A data resource specific to a pipe coupling centrally positioned within the coupling, intermediate the coupling ends. Multiple couplings are employed to connect together a string of well pipe. The data resource is adapted to be deployed at the coupling center in the space formed between the abutting ends of pipe made up into the coupling. The data resource provides information regarding the physical characteristics and locations of the coupling, the attached string pipe or the environment within which the coupling is disposed. The data resource may be a read-only component or it may be a readable and writeable component. The resource communicates with an instrument movable through the pipe and coupling. The data resource may be removably positioned at the center of the coupling or it may be permanently cemented in place. The data resource may take on the form of an annular ring with a crushable structure and suitable recesses for holding a data resource module.

Abstract: A string of pipe formed by the connection together of multiple joints of shorter pipe segments is stored in the water space adjacent an offshore drilling rig. The pipe string bends from the drilling rig floor in a semicircular arc and enters the water adjacent the drilling rig. A curving guide is used to direct the pipe string movement. A platform extension from the corner of the drilling rig is provided to position a work area above the point at which the pipe enters the water. Multiple guides may be employed for simultaneously running two strings of pipe. The string may be stored in one or more long sections or in a single continuous string. The major portions of the string or long pipe sections may be stored below the surface of the water. Provision is made for pumping fluids through the pipe string, and/or the pipe sections, to the well. The string may be stored in a sleeve.
