Abstract: The purpose of this invention is to retain an abhor nut to a power tool while the nut is not in use. More specifically it is intended to keep the abhor nut of an angle grinder attached to the grinder. Grinding abrasives for an angle grinder can be purchased with or without a center hub. The abrasives that do not have a center hub make use of the abhor nut to secure them to the grinder. When an abrasive with a center hub is used on the grinder the abhor nut is not needed. The nut is removed from the abhor and frequently becomes misplaced. This invention keeps the grinder and nut together while the nut is not being used. This is designed for angle grinders, but could be used for other power tools and machinery.

Abstract: A method of making a micro-channel structure and applying a curable ink to the micro-channel structure includes providing a substrate and depositing a single layer of a curable polymer on the substrate, the single curable layer having a layer thickness. One or more micro-channels adapted to receive curable ink are embossed into the single curable layer, the micro-channels having a micro-channel thickness that is in a range of two microns to ten microns less than the layer thickness. The single curable layer is cured to form a single cured layer so that deformations of the micro-channels or the surface of the single cured layer are reduced. Curable ink is coated over the surface and micro-channels of the single cured layer. The curable ink is removed from the surface of the single cured layer and the curable ink is cured.

Abstract: A method for forming a self-aligned hole through a substrate to form a fluid feed passage is provided by initially forming an insulating layer on a first side of a substrate having two opposing sides; and forming a feature on the insulating layer. Next, etch an opening through the insulating layer, such that the opening is physically aligned with the feature on the insulating layer; and coat the feature with a layer of protective material. Patterning the layer of protective material will expose the opening through the insulating layer. Dry etching from the first side of the substrate forms a blind feed hole in the substrate corresponding to the location of the opening in the insulating layer, the blind feed hole including a bottom. Subsequently, grind a second side of the substrate and blanket etch it to form a hole through the entire substrate.
