Abstract: The present invention is tool for transmitting torque from one end of the tool to the other comprising a housing having an input sprocket and an output sprocket connected by a race containing ball bearings whereby torque applied to one sprocket is transmitted to the other sprocket via movement of the ball bearings. The tool can be configured as a wrench for removal of nuts, bolts and screws or as a drive transmission means for applying torque from a source of rotary motion to a device requiring rotary motion to drive it.

Abstract: A containment vessel for a fuel tank comprises two-piece construction with a bottom-top or a left-right side orientation. These parts are rotationally molded with size and shape to receive a fuel oil tank. The two halves have annular flanges which bolt together for sealing the tank within. The top of the containment vessel provides a vented housing for enclosing fill, vent and furnace lines of the fuel oil tank. Heating tape may be provided to prevent freezing. Oil drips from degraded tank seams and from spills are captured within the vessel to prevent environmental damage.

Abstract: A stream of fluid mass, particularly a viscous fluid mass, is mixed by dividing the stream by high pressure fluid means into a plurality of substreams and imparting a predetermined rotational flow pattern in a first direction to alternate substreams and imparting a rotational flow pattern opposite in direction to said first direction to the remaining substream. An apparatus for achieving the foregoing is described.
