Abstract: An abrasive article comprises a porous substrate having openings extending through the porous substrate between first and second opposed major surfaces. An abrasive coating is disposed on only a portion of a first major surface of the porous substrate. The abrasive coating comprises a functional layer disposed on only a portion of a first major surface of the porous substrate, a make layer disposed on at least a portion of the functional layer opposite the porous substrate, and abrasive particles. The functional layer and the make layer independently comprise chemically crosslinked binders. The functional layer fully occludes a first portion the openings and does not fully occlude a second portion of the openings, which permits passage of abraded swarf through the abrasive article. Methods of making the abrasive article are also disclosed.

Abstract: Modified adhesive layers are prepared by contacting an adhesive layer to a modified microstructured release liner. The modified release liner has a release layer surface with a set of microstructured depressions and a discontinuous pattern of ink material located on the surface of the release layer. A portion of the discontinuous pattern of ink material overlaps with and is located within some of the depressions. The ink material comprises a non-adhesive but adhesively transferrable material, or an adhesive material. Upon removal of the adhesive from the release liner, the ink material transfers to the adhesive surface.

Abstract: In general, techniques are described for a personal protective equipment (PPE) management system (PPEMS) that uses images of optical patterns embodied on articles of personal protective equipment (PPEs) to identify safety conditions that correspond to usage of the PPEs. In one example, an article of personal protective equipment (PPE) includes a first optical pattern embodied on a surface of the article of PPE; a second optical pattern embodied on the surface of the article of PPE, wherein a spatial relation between the first optical pattern and the second optical pattern is indicative of an operational status of the article of PPE.
