Patent number: 7252764Abstract: The invention is a method for fabricating molecular filters which can separate objects approximately 1-5 nm in range, where the filtration size is controlled by using thin films of materials and technologies to form a filtration channel or pore in a middle thin film layer in a multilayered structure. Lithography is used to define two offset arrays of blind holes into the opposing sides of a multi-layer membrane. The blind holes extend across a thin central filtration layer. A selective etch is used to attack the filtration layer to form a communicating channel between the two holes. The only connection between one side of the filter and the other is through the channel in the filter layer, whose thickness, d, determines the largest size object which can traverse the filter.Type: GrantFiled: May 15, 2001Date of Patent: August 7, 2007Assignee: California Institute of TechnologyInventor: Axel Scherer

Patent number: 6264809Abstract: One electrode is provided in association with the object to be coated, the other electrode. A pre-stretched ion-exchange membrane in a thin tubular form is sandwiched inbetween two nonconductive water permeable screen tubular housings. The assembly contains a supply line that provides a water way for the electrolyte to flow from the top of the device into a lower cap, then to the lower cap reservoir that allows stabilization and disbursement of electrolyte through the rifled housing Inertia developed through this defined pattern creates a swirling action that scrubs the impurities away from the anode, and to the top of the device to be carried out top. The location of the supply line is just inside the inner screen inserted through both the upper housing and lower cap. The tubular electrode is provided to the inside of membrane housing completing the inner portion of the waterway return chamber.Type: GrantFiled: October 30, 1998Date of Patent: July 24, 2001Assignee: PTI Advanced Filtration, Inc.Inventor: Cheng H.

Patent number: 6139708Abstract: The invention relates to a system for treating a surface of an article with a liquid material by dipping. This system includes (a) a major tank having therein the liquid material for dipping the article thereinto; and (b) a circulatory mechanism for circulating the liquid material through the major tank. The circulatory mechanism is arranged to make a flow of the liquid material through the major tank such that the majority of the flow is in one direction that is substantially along the longitudinal direction of the major tank. Thus, contaminants and/or bubbles are not distributed over the entire major tank, but are effectively promptly removed from the major tank. The flow of the liquid material may include a first flow of the liquid material in the major tank and a second flow that is lower than the first flow in position. The first and second flows run substantially in parallel with each other, before the first and second flows reach a downstream end thereof in the major tank.Type: GrantFiled: August 7, 1998Date of Patent: October 31, 2000Assignees: Nissan Motor Co., Ltd., Taikisha Ltd.Inventors: Hiromi Nonomura, Hirokazu Sugiyama, Yasuo Takamizu, Shigeyoshi Okada, Toshihiko Koike

Patent number: 5591316Abstract: A method of electrocoat painting using tubular guarded membrane electrode cells. An object-to-be-electrocoat painted, or counter-electrode, is positioned or moved into a paint bath. Electrical current flow is induced between the membrane electrode cells and the counter-electrodes through the tubular guard, with the tubular guard having openings of a type that particularly allow for the flow of electricity between the electrode cells and the counter-electrode for a substantially continuous flow of paint particles around the membrane electrode cells. After painting, the counter-electrode is removed from the paint bath. Flushing fluid may be passed through the membrane electrode cells.Type: GrantFiled: June 5, 1995Date of Patent: January 7, 1997Assignee: UFS CorporationInventors: H. Frederick Hess, Jr., H.
