	Impregnation
		Impregnation is the fastest and most effective method of eliminating the problems of porosity and interior corrosion in metal castings, forgings, powdered metal parts, and plastics.
		Impregnation is beneficial for sealing porosity prior to plating, conversion coating, painting and other such surface finishes.
		More and more manufacturers are specifying impregnation for all parts, not just for purposes of salvage, but as part of their guarantee against defects.

	Class Definition for Class 442 - FABRIC (WOVEN, KNITTED, OR NONWOVEN TEXTILE OR CLOTH, ETC.)
		Subject matter wherein the fabric is coated or impregnated with a material which is neither a foamed material nor a metal or alloy layer, which is not associated with any other preformed layer other than additional coatings or impregnations, and which is not characterized by a particular or differential weave or knit pattern.
		Subject matter wherein the coating or impregnation is weather proof, water vapor resistant, or moisture resistant, the weather proofness or water vapor resistance or moisture resistance being specifically stated.
		Subject matter wherein the coating or impregnation which is not specified as improving the "hand" or increasing the softness of the fabric acts as a lubricant or a surface friction reducing agent.

		In this case, the impregnation fluid passes strictly in a concurrent flow direction, that is, impregnation fluid and chips move in a downwards direction.
		The impregnated chips are continuously output via output means, here in the form of an outlet 10, possibly also in combination with bottom scrapers (not shown in the drawing), at the bottom of the impregnation vessel 30.
		impregnation fluid is established in a direction opposite to the sinking motion of the chips in at least the upper part of the impregnation vessel.

		The reference claims that greater wetout and impregnation are achieved due to the pressure head, the heating of the fibers and the capillary action of the fibers.
		A"wall"of resin is maintained upstream from the impregnation chamber to minimize the air that is trapped between the resin and the fiber bundles and to prevent air from entering the high pressure impregnation chamber.
		For instance, the impregnation device of this invention may be mounted proximate rotating fiber spools in order to obtain the benefits of this invention in conducting filament winding operations, wherein both the fiber spools and the impregnation head (s) would rotate about a fixed or axially moving mandrel or work piece.

	Resin Impregnation
		Impregnation is the process of sealing leaks in machined components made of iron, bronze, aluminum, zinc, magnesium, steel, powder metal and plastics, as well as alloys and ceramics.
		Impregnation can also be used before electroplating, lacquering and applying baked enamel finishes.
		In these applications, impregnation prevents bleedout from acid etches and electrolytes, as well as gassing and blistering by materials absorbed into porous areas that finishes have sealed.

	New Impregnation Thermocondencical Technology of Production
		The thermocondense way of impregnation is controlled process and assumes uniform distribution of a impregnative liquid in a structure of a capillary-porous material at opportunity of regulation of quantity of absorbed substance.
		Opportunity of uniform distribution of an active component irrespective of the form of a carrier is shown at impregnation of the catalytic carriers, at impregnation of fibrous materials, etc. The inculcation of new technology in the majority of cases is possible on the base equipment of the manufacture without its replacement or reconstruction.
		At impregnation of fibrous materials has managed to increase quantity of a component that was laid on the body surface up to 30 %, as well as to supply significant improvement of penetration of the high vicious structures inwards of filaments of a material.

		The Impregnation Kit Area is an approximately 300,000 square foot, rectangular area in the southwestern portion of Nansemond, about 1000 feet from the Nansemond River.
		Impregnation kits consist of XXCC3 (a fine, white, granular, crystal powder) and a "honey-like syrup" or "fl waxy material." XXCC3 was used to neutralize chemical agents.
		In the summer of 1999, a contractor for the Corps took samples of the soil in the Impregnation Kit Area to confirm that the excavation had successfully removed contaminated soil and to check for hazardous substances, pollutants, and contaminants in 20 acres surrounding the excavation.

	Blank Impregnation
		I intend to impregnate one with one final coat of spar and finish the other rod with the usual three coats of varnish.
		Pour the impregnation sauce back into the original can, give it a squirt of Bloxygen, and seal - a one quart can should be more than enough to impregnate ten to 20 or more 2/2 blanks.
		I think the idea behind impregnation is not only to provide a liquid and vapor barrier (which is what varnish does) but also to fill in the parts of the bamboo structure with resin so that it can't physically take on water vapor.

	Automotive Finishing: VACUUM IMPREGNATION: An Alternative Method - electronic component sealing technique
		Vacuum impregnation sealing is not an external coating process, rather it is a process that internally seals parts using a vacuum pressure chamber, which impregnates liquid resin into minute pores in the part's surface.
		Impregnation sealing solved our problems for a small price per part increase, without the high cost of a tooling change or major redesign.
		Given the fact that vacuum impregnation helps manufacturers meet their quality goals, it should no longer be seen as a value-added process, but rather a value-guaranteed process.

	Chromia-bonded refractory body devoid of vitreous and sintered bonding - Patent 4077808 (Site not responding. Last check: 2007-11-03)
		The hardening is accomplished by impregnating the porous body with a metal compound, which may be in solution, which compound is capable of being converted to the metal oxide in situ at a temperature below sintering temperature in the range of from about 600.degree.
		This also may be accomplished by impregnation of the porous structure with a water solution of a soluble metal compound convertible to an oxide and subsequently converting same to the oxide by simply elevating the temperature to the required conversion point.
		This was accomplished by impregnating the refractory base material with a nitrate, chloride, acetate or other highly water soluble salt or an acid of the oxide desired, and then converting to the metal oxide by heating slowly to an elevated temperature.
