Abstract: A transformer oil holding assembly for holding transformer oil. The transformer oil holding assembly includes a tank subassembly with one or more tanks for containing the transformer oil, the tank subassembly having a lower exterior surface adapted for engagement with a ground surface, and one or more sets of wheels for at least partially supporting the tank subassembly, each set of wheels being movable between a lowered position and a raised position, a suspension subassembly mounted to the tank subassembly, and one or more stop subassemblies for at least partially maintaining the set of wheels in the lowered position. Each stop subassembly includes a stop lever movable between an engageable condition, in which a stop element is engageable with the suspension subassembly to maintain the set of wheels in the lowered position, and a disengaged condition, in which the stop element is disengaged from the suspension subassembly.

Abstract: A mud saver valve for retaining drilling fluid in the Kelly of a rotary drilling rig for insertion into a Kelly sub with an enlarged opening inside having a valve and hollow piston closing the flow in a first position and having flow through when the hollow piston is moved by flow against a spring to an open position compressing a spring to stack height, the spring being magnetized to provide magnetic latching to assist in holding the hollow piston in the open position at flow rates lower than it would otherwise be held open.

Abstract: Method and apparatus for monitoring formation of deposits of solid particles from flue gas onto furnace walls formed of welded-together tubes through which cooling medium flows. For the entire surface of the walls, the exact surface temperature is detected with infrared cameras, offset by 90° relative to one another, via a thermal image obtained of a surface development of the furnace. This exact surface temperature is compared with the temperature of the cooling medium from measurement locations. Individual images from the cameras are composed to form an overall development of the inner surface of the furnace walls. The coordinates of the deposits on the walls are determined from the overall development, and the thickness of the deposits is determined from the temperature comparison.

Abstract: TURBINE BLASTING MACHINE, more specifically, referring to a blasting machine with a conventional turbine equipped with its own turbine feeding system that uses more effective conventional turbines and that have the possibility of directing the blade with a simple system of guiding the abrasive to the center of the turbine(s), which can be done by only gravity or by the combination of gravity and an auger.
