Abstract: A transport floor connected to the transport watercraft. An elevated drilling floor integrally connected to the transport floor; supporting a derrick comprising at least two rails for supporting a traveling top drive supported by a crown block. The crown block is connected to the derrick. The elevated drilling floor has a control panel comprising a power throttle for operating the top drive.

Abstract: A transport rig having at least one duel axel, with a single point suspension. The transport rig has at least two pneumatic independently and vertically adjustable load supporting axels. A rig floor is mounted above the axels. The rig floor can have a drawworks assembly, a drive engine operatively connected to the drawworks assembly, and a second engine for providing hydraulic power.

Abstract: A top drive power swivel assembly for well drilling rigs having a travelling frame for moving along a drilling tower. The travelling frame has at least two lower and two upper travelling frame extensions. A housing has at least two upper and two lower housing extensions each with an opening. A first connector penetrates openings of upper travelling frame extensions and openings of an upper housing extensions engaging the travelling frame to the housing. A second connector penetrates openings of lower travelling frame extensions and openings of lower housing extensions to securely engage the travelling frame to the housing. A top drive power swivel mounts to the housing and the top drive power swivel receives power from hydraulic motors. Various sheave assemblies mounted to the travelling frame engage a hoisting means. Guide wheel assemblies disposed on the travelling frame engage the tubulars.

Abstract: An automatic driller for controlling a rotating primary mover. The automatic driller has a manual brake handle. The manual brake handle has a stroke. A first elastic means applies a first tension to the manual brake handle. A swivel bracket is connected to the first elastic means. The first elastic means provides a first tension onto the swivel bracket.

Abstract: A shock mounted top drive comprising a traveling frame for moving along a drilling tower, the traveling frame comprising a first and second housing section, at least one set of sheaves mounted to the upper section of each housing section, a guide wheel assembly secured to the outboard side of each housing section, at least one swivel support disposed on the inboard side of each housing section, at least one shock absorber disposed on each swivel support, and at least one upper stop connected to the inboard side of each housing section. A top drive power swivel, which has a housing and a rotating drive shaft, is secured to the traveling frame using a plurality of removable top drive retainers. The top drive retainers engage the inboard side of each housing section between the upper stops and the shock absorbers.

Abstract: An apparatus that can be used during drilling operations for the purposes of clamping and holding drilling tubulars is disclosed. The embodiments relate to machinery that clamp and hold drilling tubulars to allow assembly to a specified torque or disassembly of the tubulars. The apparatus comprises a first grip with teeth inserts housed in a gripping block that opposes a second grip with teeth inserts housed in a second gripping block. The first and second grips are spaced and adapted to accommodate a range of diameters of drilling tubulars. Further, the gripping blocks are held by opposing arms connected to a driving means to create a tightening or loosening movement of the grips and maintain a certain orientation with regard to the tubulars.

Abstract: An earth drilling machine includes a mast, a crown block assembly mounted on the mast top for providing a drilling line having front sheaves, a fast line sheave mounted to a crown block sheave for reeving the drilling line, a drawworks drum, and a traveling frame assembly a midpoint of a width of a drawworks assembly aligned with the fast line sheave. The drawworks drum has a drum axis, the front sheaves are all aligned on a front axis, the fast line sheave and the deadline sheave are both aligned on a back axis, and the traveling sheaves are aligned on a traveling frame axis. The front axis, back axis, and traveling frame axis are parallel to the drum axis. The crown cross over sheave defines a cross over axis and the cross over axis is mounted perpendicular to the drum axis.

Abstract: A tribocharge applicator device for application of a powdered material to a substrate is disclosed. The device includes an inlet for pressurized conveying gas, an inlet for powdered polymeric material having a first dielectric constant, a mixing chamber, a discharge barrel and a charge module. The charge module includes: at least two spiral charging elements disposed inside and coaxially aligned with respect to the barrel, each spiral charging element comprising an elongated sheet of a different material having a second dielectric constant. The proximal end of the elongated sheet is twisted about its longitudinal axis with respect to the distal end such that each longitudinal edge of the sheet forms a spiral.
