Abstract: Abrasive articles possessing a highly open (porous) structure and uniform abrasive grit distribution are disclosed. The abrasive articles are fabricated using a metal matrix (e.g., fine nickel, tin, bronze and abrasives). The open structure is controlled with a porosity scheme, including interconnected porosity (e.g., formed by leaching of dispersoid), closed porosity (e.g., induced by adding a hollow micro-spheres and/or sacrificial pore-forming additives), and/or intrinsic porosity (e.g., controlled via matrix component selection to provide desired densification). In some cases, manufacturing process temperatures for achieving near full density of metal bond with fillers and abrasives, are below the melting point of the filler used, although sacrificial fillers may be used as well. The resulting abrasive articles are useful in high performance cutting and grinding operations, such as back-grinding silicon, alumina titanium carbide, and silicon carbide wafers to very fine surface finish values.

Abstract: There is disclosed a furring strip system wherein furring strips serve to provide a space to promote drainage and drying between the exterior siding or cladding and the underlying construction. These furring strips may be pre-attached to at least one side of a water resistive barrier (WRB—sometimes referred to as “Housewrap”) Additionally, it has been found that the use of closed cell polyethylene foam furring strips significantly reduces the amount of water penetration and leakage that occurs along the fasteners through the furring strips and the WRB onto the unprotected sheathing therebeneath, i.e. the closed cell foam furring strips provide a “gasketing effect”, and “self-sealing” as the fastener, whether it be a staple or nail, penetrates the closed cell polyethylene foam furring strip. The usefulness of the invention is the same regardless of whether the furring strips are pre-attached to the WRB or are added before or after the WRB has been applied to the building structure.

Abstract: In a method for correcting the fuel concentration in a regeneration gas flow of a tank venting device, the fuel concentration is determined, and a defined regeneration gas flow rate is set and supplied to the engine to use the regeneration gas in the combustion process. Then, a reference composition is determined and the flow rate is varied.

A pre-specified quantity of fuel is corrected by the first correction value and the exhaust gas composition is determined again after the corrected fuel quantity has been supplied. A second correction value is determined by which the corrected fuel quantity is further corrected to set the exhaust gas composition to the reference composition. The fuel concentration of the regeneration gas flow is corrected by the first and the second correction values.
