| 20080264023 | Fabrication method of diesel particulate filter element - A diesel engine exhaust gas filter [ | 10-30-2008 |
| 20090013659 | Apparatus and Method for Discontinuous Welding of Metallic Fibers, Method for Filtering Exhaust Gases and Exhaust-Gas Treatment Component - An apparatus and a method for welding metallic fibers to form a knitted fabric having a predetermined width, include feeding a composite of metallic fibers to an apparatus for welding the fibers to form a knitted fabric, and separately welding a plurality of partial sections of the composite in a time period, in which the composite is at a standstill, for example through the use of a plurality of welding electrode pairs which are disposed over the width of the composite. A method for filtering exhaust gases and an exhaust-gas treatment component are also provided. | 01-15-2009 |
| 20090038280 | Stainless Steel For Filter Applications - A filter comprising a porous sintered stainless steel is provided. The filter includes 10-30% chromium, 5-25% nickel, 0.5-3% manganese; 1-4% silicon, and 0-3% molybdenum with the remainder being iron and inevitable impurities. The sintered steel has a density less than 80% of full density. The use of a stainless steel powder for the preparation of a filter having improved permeability at high temperatures also is described. | 02-12-2009 |
| 20110067372 | EXPANDED METAL AND PROCESS OF MAKING THE SAME - An expanded metal is provided including a plurality of integral strands defining diamond shapes, each diamond shape having a long dimension as measured from two opposing vertices and a short dimension, generally transverse to the long direction, as measured between two other opposing vertices, such that the long dimension is less than twice the short dimension. | 03-24-2011 |
| 20120266579 | LOW DENSITY MIST COLLECTOR PAD - A wire mesh mist collector pad having multiple density zones, the zones being arranged other than to provide a constantly increasing density gradient, provides a reduced pressure drop and increased capacity. For example, the pad can include at least three zones with the zones arranged so that the density gradient in the direction of gas flow through the pad varies from low to high to low or from high to low to high. | 10-25-2012 |
| 20140245711 | EXPANDED METAL AND PROCESS OF MAKING THE SAME - An expanded metal is provided including a plurality of integral strands defining diamond shapes, each diamond shape having a long dimension as measured from two opposing vertices and a short dimension, generally transverse to the long direction, as measured between two other opposing vertices, such that the long dimension is less than twice the short dimension. | 09-04-2014 |
| 20160074921 | MACHINE TO PRODUCE PERFORATED METAL STOCK - A machine to form a plurality of perforations in an elongate strip of material is provided. The machine includes opposed first and second wheels that receive the strip therethrough. The first wheel has a plurality of spaced teeth each disposed at a lateral position about the circumference of the first wheel with consistent spacing therebetween. The second wheel has two or more radial projections that each are disposed outboard of the plurality of spaced teeth in the first wheel. The interaction of the plurality of teeth and radial projections upon the elongate strip forms a plurality of perforations in the strip. Opposed third and fourth wheels are provided after the first and second wheels. The fourth wheel includes at least one indented portion that is aligned to interact with flared portions from the elongate strip and urge the flared portions toward the remaining surface of the elongate strip. | 03-17-2016 |

| 20140250847 | Wire Mesh Filter with Improved Wire and Method of Making the Wire - A filter for use in safety air bags as employed in vehicles and the like comprises compressed corrugated wire wherein the corrugations are formed as a periodic sequence of substantially identical first sinusoidal waves coplanar in one orientation of a first given amplitude and pitch and a periodic sequence of substantially identical second sinusoidal waves of a second amplitude and pitch different than the first given amplitude and pitch oriented orthogonal to the plane of the first waves to form a wire with complex three dimensional waves. The wires so formed are wrapped about a mandrel in multiple layers and the ring so formed distorted into an oval shape that is inserted into a filter forming die. A plunger then is forced under high pressure into the die to form the compressed wire filter. The layers of undulations of the wire interlock to preclude separation of the compressed layers during deployment of an air bag. | 09-11-2014 |
