  • Patent number: 9957881
    Abstract: A charge air cooler cools charge air compressed with a compressor. The charge air cooler includes a shell and an inner tube, which is accommodated in the shell and exposed to an interior of the shell. The shell has an inlet and an inlet to enable charge air to flow through the inlet, the interior of the shell, and the inlet and to pass around the inner tube in the shell. The inner tube is configured to draw working fluid from a transmission device of the vehicle or an engine and to conduct heat exchange between charge air, which flows through the interior of the shell, and working fluid to warm working fluid.

  • Patent number: 7004230
    Abstract: Incorporation of rice hull ash into investment casting shell molds improves the permeability, shell build thickness, and/or shell build uniformity of the molds. A method to make the molds entails mixing refractory filler, rice hull ash, and preferably a fiber to form a dry blend; mixing the dry blend with a binder sol to form a refractory slurry, and employing the refractory slurry to produce an investment casting shell mold.

  • Patent number: 6991022
    Abstract: The invention relates to investment casting shell molds and their method of manufacture. The method entails mixing fiber such as ceramic refractory fiber and organic fiber with ceramic filler to form a dry blend. The dry blend is mixed with a binder sol such as colloidal silica sol to form slurry. An expendable preform is dipped into the slurry, stuccoed and dried. This step is repeated until a ceramic shell of a desired thickness is formed over the expendable preform. The expendable preform then is removed, and the green ceramic shell is fired. Molten metal then may be poured into the shell to form a metal casting.

  • Patent number: 6257316
    Abstract: A process for rapidly forming a ceramic shell mold on an expendable pattern is disclosed. The process entails use of refractory slurries which include a large particle size colloidal silica sol binder. The colloidal silica sol binder has an average particle size of about 40 nanometers, i.e., about 3-4 times larger than colloidal silica sol binders heretofore employed in manufacture of ceramic shell molds. The use of the large particle sols yields unfired ceramic shell molds which have about 40% to about 70% greater unfired strengths compared to ceramic shells made with prior art small particle size silica sols. Prime coats and refractory back-up coats which use the large particle size sol dry about 30% to about 40% faster than prime coats and back up coats which employ the smaller particle size silica sols of the prior art.

  • Patent number: 6214102
    Abstract: A method of vacuum forming of aqueous, fibrous slurries and products produced thereby are disclosed. The method entails forming an aqueous slurry of ceramic fiber, cationic starch and silica sol. The silica has, based on total weight of the sol, about 50% silica having a particle size range of from about 7 nm to about 200 nm and a specific surface area of about 100 m2/gm to about 10 m2/gm. The slurry is passed through a porous screen under a vacuum pressure deposit the solids content onto the screen to produce high strength products.
