| 055520000 | SPIRAL FILTER MEDIA | 6 |
| 20080264022 | Filter for use in a gas generator - A filter for use in a gas generator of a safety arrangement in vehicles, has several layers of a woven metal fabric consisting of metal wires which are woven together. The woven metal fabric is preferably calendered, wound to form a roll, and pressed to form said filter. | 10-30-2008 |
| 20090094953 | COMPACT FILTER ELEMENT AND METHOD FOR SEALING AN END THEREOF - A compact filter element and a method for sealing an end thereof are provided. The compact filter element includes a filter material formed into a winding and an adhesive element, having a predetermined size and shape, that fixes an outer end portion of the filter material to an outer side portion of the filter material. The adhesive element provides improved control of the amount of adhesive applied to the filter element, because the adhesive element has a predetermined amount of adhesive. Thus, the costs associated with the adhesive process can be reduced, by minimizing excessive use of adhesive. Also, the process of applying the adhesive element is a faster process and requires less expensive equipment to implement than a hot melt process. | 04-16-2009 |
| 20090235624 | Fluid flow filter and method of making and using - A filter well suited for paint arrestor usage having a monolithic high loft manmade fiber body with a convoluted flow contact surface. The filter is preferably formed by a convoluter as in one with a roller set and blade cutter to form mirror image fiber filter sheets from a received fiber batt. Provided is a well mixed proper fiber blend, such as one having a set of fibers made of a majority of course fibers joined by way of thermal bonding fibers which facilitate, during convoluting, formation of a crisp cut and high integrity three dimensional surface, as in one of rows of peaks separated by valleys. The projection/recess arrangement over the flow contact surface as well as the thickness and relative projection-to-base dimensions are arranged to provide a high paint holding capacity without too fast a load up of, for example, paint particles and while avoiding too great of a pressure drop within that load up time. | 09-24-2009 |
| 20110289895 | Ceramic Filter Element with Structural Elements and Production Method - A ceramic filter element of ceramic material has an exterior surface that is provided with structural elements. The structural elements are produced by a non-cutting method. The structural elements are molded in the ceramic material in the form of grids, periodic patterns, irregular patterns, lettering or labels. | 12-01-2011 |
| 20120060457 | COATED HONEYCOMB BODY AND METHOD FOR PRODUCING A COATED HONEYCOMB BODY - A method for producing a metallic honeycomb body from metallic layers with channels through which an exhaust gas stream can flow, includes providing the honeycomb body with a coating. Such honeycomb bodies are used in exhaust gas systems of preferably mobile internal combustion engines as catalyst carrier bodies, filters, mixers and/or adsorbers. The coating is provided in a two-stage application and enables the production of exceptionally advantageous coated metallic honeycomb bodies, which are distinguished by a large coating surface and a low flow resistance. At the same time, an exceptionally large surface enlargement is provided in the honeycomb body while using a smaller amount of coating. A honeycomb body is also provided. | 03-15-2012 |
| 20160089623 | METHOD OF MANUFACTURING FILTER PIPE FOR VEHICLE AND FILTER PIPE FOR VEHICLE - A method of manufacturing a filter pipe for vehicles which has an expanded tube portion with a different diameter at one side and is provided with a plurality of through holes formed along a circumferential direction includes: forming the plurality of through holes in a mother member; forming furrows at one end portion of the mother member; forming a planar member having the plurality of through holes and the furrows by a shearing process of the mother member; bending the planar member in a tubular shape and spreading the furrows to form an area where the furrows are formed in an expanded tube shape; and adhering both facing end portions of the planar member so as to form a body having the expanded tube portion at one side thereof. | 03-31-2016 |
