Abstract: A method of providing a salt solution at a wellbore site includes delivering solid salt in a mixing tank containing water from a local source and pumping the water through nozzles in the mixing tank using a pump adjacent to the mixing tank to circulate the water in the mixing tank and form a concentrated brine by dissolving the solid salt in the water. The concentrated brine is transferred from the mixing tank to a reservoir using the pump, and the concentrated brine is diluted with additional water from the local source to form a dilute brine. A related mixing tank and a system including the mixing tank and a vehicle structured and configured for travel over a roadway and within an oilfield site.

Abstract: An animal walker or conditioning system. The preferred embodiment of the present invention contemplates a horse walker or conditioner incorporating a direct drive hydraulic motor, the motor configured to provide a powered bearing surface to support and axially rotate a vertical shaft having laterally extending arms emanating therefrom, which arms can be utilized to direct a horse or other animal in a circular path about the vertical shaft. The unique design utilizes an off the shelf direct drive hydraulic motor and conventional power system, with the hydraulic power unit preferably situated away from the vertical shaft, and power and control lines running underground to the hydraulic motor supporting the vertical shaft.

Abstract: A device for rewinding used heat transfer foil onto an empty takeup spool so that heat transfer foil can be easily, compactly and cleanly disposed. The device is provided with a rotating takeup spool onto which the used heat transfer foil is wound. The used heat transfer foil is guided onto the takeup spool in an orderly sequence by a reciprocating arm of a travelling guide block which moves parallel to the takeup spool and travels in unison with rotation of the spool. The power train which powers rotation of the takeup spool and reciprocation of the arm is provided with a slip-type clutch disk which allows the takeup spool to speed up, slow down, and stop and start rotating in response to availability of used heat transfer foil.
