Abstract: To improve the characteristics of fuel to be used in an engine of an automotive vehicle or a boat or ship, to reduce an amount of harmful substances in emission and to enhance a fuel consumption rate, a device for improving the characteristics of fuel is provided and connected between the engine of the automotive vehicle or the boat or ship and a fuel tank. A fuel pipe spirally wound is arranged within a hexagonal housing in outer shape. A carbon rod is provided inside of the fuel pipe and a coil is wound around its outer periphery. Powder of metal, mineral and oxide is filled between the fuel pipe and the inner wall of the housing and solidified with silicone resin. The fuel flows through an interior of the fuel pipe in a spiral manner to be fed to the engine.

Abstract: A fluid squeeze monitor downhole tool and a method of monitoring formation squeeze features a tool body that can be placed downhole at a desired elevational location to produce a controlled, localized reduction of pressure head and measure the resultant inward displacement of the borehole wall. The reduction in head is accomplished by draining the fluid in a bladder (or collapsible container) located on the tool body into a reservoir "sump" that is incorporated into the downhole tool.
