Publication number: 20080184891Abstract: An evaporative emissions filter for an engine air induction system. The evaporative emissions filter includes a hydrocarbon vapor-adsorbent member disposed within the air induction system outside the direct air flow path. A mechanism is provided for mounting the evaporative emissions filter within the air induction system. Hydrocarbon vapors present in the air induction system after engine shut-down are substantially retained in the adsorbent member until air flows through the air induction system after the engine starts.Type: ApplicationFiled: January 29, 2008Publication date: August 7, 2008Inventors: Gary B.

Patent number: 6893489Abstract: A coating, such as ink or paint, is used, where particles in the coating are selected based on electric, magnetic, or light/photo properties, and are dispersed in the coating to provide a desired physical color. In one approach, the application of the coating to the substrate such as paper is controlled using an electric or magnetic field. In another approach, a pattern is formed in a coating on a substrate by targeting an electric, magnetic or photo field to specific locations on the coating. In yet another approach, the color of a coating that is applied to an object is shifted to match a background color so that the coating appears to be erased. In this approach, the coating may be in the form of a label, such as a bar code, that can be read by a scanner at a point of sale location. In another approach a pattern or code is scrambled or removed by applying an electric, magnetic, or photo field to specific locations on the coating or substrate.Type: GrantFiled: December 20, 2001Date of Patent: May 17, 2005Assignee: Honeywell International Inc.Inventors: Kwok-Wai Lem, Ronald P.

Patent number: 6726751Abstract: A filter material includes a filter pad made from a thin, nonwoven fiber mat which has been accordion-pleated, compressed into a unit having a large number of substantially parallel interconnected filter strips, and treated to retain the filter strips in substantially parallel relation to each other. In a preferred embodiment, activated carbon particles are operatively associated with the filter pad. Selected fibers of the nonwoven fiber material are hollow fibers, each having an outer surface, a hollow internal cavity, and an extended slot formed therein, between the hollow internal cavity and the outer fiber surface. Carbon particles may be located between selected filter strips, and additional carbon particles may be disposed within the cavities of the hollow fibers. Methods of forming the filter material, and a filter element made with the filter material are also disclosed.Type: GrantFiled: November 13, 2001Date of Patent: April 27, 2004Inventors: Daniel E.

Patent number: 6706092Abstract: Modification, neutralization and/or decontamination of airborne biological and/or chemical contaminants from a breathable atmosphere by subjecting the breathable atmosphere to a filter which is formed from a plurality of polymeric multilobal fibers. These fibers include a central core with T-shaped lobes projecting therefrom, wherein each T-shaped lobe has a leg and a cap. The lobes define a longitudinally extending internal cavity between two adjacent legs that extends the entire length of the fiber. The filter is impregnated with a biological and/or chemical decontamination reagent for chemically modifying, neutralizing and/or decontaminating airborne biological and/or chemical contaminants from a breathable atmosphere. A filter projection preferably extends into an external reservoir containing a supply of biological and/or chemical decontamination reagent. This configuration increases the capacity and efficiency of the filter, and causes a lower pressure differential across the filter.Type: GrantFiled: April 17, 2002Date of Patent: March 16, 2004Assignee: AlliedSignal Inc.Inventors: Ronald P. Rohrbach, Daniel E. Bause, Gordon W. Jones, Peter D. Unger

Patent number: 6623550Abstract: A robust, relatively simple air quality control system that can control the air quality in buildings during both the heating and cooling seasons. In one illustrative embodiment, a first air stream is directed through an air treatment module and back into the inside space. A desiccant in the air treatment module adsorbs water, volatile organic compounds and/or particulate material from the first air stream. A second air stream is then directed through the air treatment module to a location outside of the inside space. The second air stream is preferably heated relative to the first air stream so that at least a portion of the adsorbed water, volatile organic compounds and/or particulate material are desorbed from the desiccant into the second air stream. The second air stream carries the desorbed water, volatile organic compounds and/or particulate material to a location outside the inside space.Type: GrantFiled: June 5, 2002Date of Patent: September 23, 2003Assignee: Honeywell International Inc.Inventors: Dipak I.

Patent number: 6514306Abstract: A fibrous element is described. The fibrous element includes a container member and an anti-microbial agent, wherein the anti-microbial agent is disposed within the container member. The container member can include structures such as an elongated fiber having multiple lobes with a longitudinally extending internal cavity including an opening from the internal cavity to the outer fiber formed between adjacent lobes, an elongated fiber having an internal longitudinally extending cavity having a longitudinally extending opening, and a particulate. The anti-microbial agent is capable of diffusing out of the container member and throughout the fibrous element in response to elevated relative humidity levels in order to contact and kill a microbial population.Type: GrantFiled: January 27, 2000Date of Patent: February 4, 2003Assignee: Honeywell International Inc.Inventors: Ronald P.

Patent number: 6505597Abstract: A cleansing oil filter includes a housing, a porous filter element disposed in the housing, and a quantity of liquid antioxidant/additive solution in the housing associated with the filter element. Preferably, the filter contains at least 10 ml of antioxidant, and more preferably, between 20 and 100 ml of antioxidant. A substantial quantity of the liquid antioxidant/additive solution is available for immediate release when oil flows through the filter. A method of converting an internal combustion engine from a petroleum-based lubricating oil to a botanically-based lubricating oil involves draining a petroleum-based lubricating oil out of the engine, removing an oil filter from the engine and replacing it with a first cleansing filter having a quantity of liquid antioxidant/additive solution therein, adding a first batch of a botanically-based lubricating oil to the engine, running the engine until warm, and replacing the oil and filter a second time using botanically-based oil.Type: GrantFiled: May 30, 2001Date of Patent: January 14, 2003Assignee: Honeywell International Inc.Inventors: Gary Zulauf, Ronald P.
