A tool adapted to form and method of forming a tapped hole within a workpiece in a single pass, includes a piercing section operable to punch a pilot hole in and produce a slug attached to the workpiece, and a tapping section operable to form a female thread along the periphery of the hole, and more preferably, an extruding section operable to push workpiece material away from the exterior surface defined thereby, an expanding section operable to expand the diameter of the hole, a sealing section operable to seal the hole during a hydroforming process, and a burnishing section operable to further expand and treat the periphery of the hole prior to tapping.

An apparatus and method for prevention of corrosion with the cooling system of an internal combustion engine is disclosed. The apparatus includes a pressurized inert gas source and a fluid delivery system whereby the gas is dispersed within the cooling system to expel corrosion inducing fluids such as oxygen and water vapor. Methods of use are also disclosed.

A vapor compression distiller having a shell for enclosing a pair of heat exchange tube bundles each having one end connected to a steam chest and its other end connected to a condensate collecting chamber. A vapor compressor has its inlet connected to the shell and the outlet to one steam chest which is coupled to a second steam chest through a steam ejector for elevating the inlet pressure to the second heat exchange tube bundle. A half partition extends across the lower end of the vessel and between the wells to divide the lower portion of the vessel into two sections which are in communication across the upper end of the vessel. One well is connected to receive fresh feed liquid and the other includes a density sensor to discharge a portion of the concentrate to therein maintain a desired concentrate level and each well is connected to a spray nozzle manifold disposed in its respective shell section.
