Abstract: A method for dispersing liquid over a desired location, the method comprising a pressurized tank having a main body, an inlet in fluid communication with the main body for introducing liquid to the main body, an outlet in fluid communication with the main body for dispersing the liquid, and an air inlet for charging air under pressure into the main body, where the improvement comprises providing a diffuser for slowing down pressurized air entering the main body from the inlet.

Abstract: A cargo loading system for loading freight into or out of the cargo hold, the system comprising: a tilt control means which can be actuated by control signals in such a way that variances in tilt of a palletized load can be immediately righted; a control panel for actuation by personnel; a power source to the control panel; and a trailer base connected to the tilt control means for accepting freight.

Abstract: Method and apparatus for automatically changing engine lubricating oil while the engine is running, in which small increments of used lubricating oil are periodically removed from the lubricating oil system, and substantially simultaneously with the removal of each increment of used oil, a corresponding increment of fresh oil is delivered to the lubricating oil system, so the volume of oil in the lubricating system is not reduced by the removal. Oil sump level sensing determines the destination of each used oil increment that is removed. If the sump level is not substantially below a predetermined satisfactory operating level when an increment of used oil is removed, the increment is delivered to the fuel tank for burnoff with the fuel for diesel engines, or to a holding tank for other engines, in a normal oil change mode of operation.
