A tool assembly and a process for using it is provided, wherein a single elongate handle member may be used, through a small hole at the ground surface, to reach underground pipes for installing different sized strap “T” couplings on different sized pipes, and for driving sleeve members associated with said strap “T” couplings, pneumatically, from above ground, to engage pipes at various locations below ground.

A tool assembly is provided for working on underground pipes, through a small hole at the pipe surface, by means of an elongate handle member that reaches into the hole, and has a coupling at the lower end thereof, whereby various ones of selected tools may be quickly connected to and disconnected from the lower end of the handle member, by means of a universal coupling, and whereby the tools can be pneumatically driven from above ground.

A transportable GTL processing facility constructed on an inland barge is provided. Also provided is a process for producing liquid hydrocarbons from natural gas utilizing a transportable GTL processing facility. The facility and process may be used to access and convert stranded natural gas in an economical fashion into liquid hydrocarbons. Further provided is a transportable GTL processing facility and process for producing liquid hydrocarbons wherein the liquid hydrocarbons are upgraded into transportation fuels and other locally usable materials.

A variable speed winch including a uni-directional drum rotatable initially by the clockwise motion of a handle in a clockwise sense only. The winch also includes a gear selector including a control plate rotatable with respect to the drum into an extreme clockwise position wherein a first gear ratio is selected. The gear selector further includes ratchet structure, splined to a shaft rotatable by the handle. The ratchet structure is slidable axially with respect to the shaft under the influence of a cam structure responsive to the relative angular displacements of the handle with respect to the control plate. The control plate has recesses engageable by respective spring-loaded balls captively supported by the ratchet structure. The balls are adapted to enter and lock within the recesses in response to an anti-clockwise rotation of the handle sufficient to cause axial sliding of the ratchet structure, with respect to the shaft, under the influence of the cam structure. Subsequent clockwise rotation of the handle gives the drum a clockwise speed equal to that of the handle, and subsequent anti-clockwise rotation of the handle causes the drum to continue clockwise rotation at an intermediate higher speed with reference to the handle, up to a point where the control plate is urged into an extreme anti-clockwise position with respect to the drum to select a second gear ratio, whereupon the reversal of the handle and subsequent clockwise rotation thereof causes continued clockwise rotation of the drum at a still higher speed with reference to the handle, and reversal of the handle and subsequent further anti-clockwise rotation thereof causes the drum to revert to the intermediate higher speed while continuing to rotate clockwise.

A tool and a process of using the tool is provided, whereby nuts, bolts, etc. may be worked on in a hole below ground that is substantially deeper than the hole opening at ground level, wherein a ratchet wrench tool assembly is provided, with the ratchet being below ground and having a plurality of different sized wrench heads adapted to be used therewith, and actuable from above ground by moving an elongate handle backwardly and forwardly, to have a below-ground pawl engage different teeth of the ratchet.
