Abstract: Apparatus and associated methods relate to forming an epitaxial layer of aluminum on an aluminum-nitride compound. The aluminum is epitaxially grown on the crystalline aluminum-nitride compound by maintaining temperature of a crystalline aluminum-nitride compound below a cluster-favoring temperature threshold within a vacuum chamber. Then, the crystalline aluminum-nitride compound is exposed to atoms of elemental aluminum for a predetermined time duration. The aluminum is epitaxially grown in this fashion for a predetermined time duration so as to produce a layer of epitaxial aluminum of a predetermined thickness. Such epitaxially-grown mono-crystalline aluminum has a lower resistivity than poly-crystalline aluminum.

Abstract: A dewatering box cover including a main body having a leading edge, a trailing edge opposite the leading edge, a first edge, a second side edge opposite the first side edge, a top surface, and a bottom surface. A first slot is formed within the main body having a first portion and a second portion angled relative to the first portion so as to form a V-shape. A plurality of second slots are formed within the main body at both sides of the first slot. The second slots and the first and second portions of the first slot extend from the top surface to the bottom surface of the main body at an angle relative to horizontal of 30° to 70° and at an angle relative to vertical of 20° to 45°.

Abstract: A dewatering box cover including a main body having a leading edge, a trailing edge opposite the leading edge, a first side edge, a second side edge opposite the first side edge, a top surface, and a bottom surface and a plurality of sets of holes formed within the main body. The holes within each set are aligned with one another along an imaginary line that is angled from 30° to 70° relative to horizontal and the holes extend downwards from the top surface of the main body towards the bottom surface of the main body at an angle of 20° to 45° relative to vertical.

Abstract: A method for cleaning a belt of a through air drying papermaking machine in which a high pressure shower is configured to traverse across a width of the belt of the papermaking machine while ejecting water onto the belt, and a vacuum box is operatively connected to the high pressure shower. The high pressure shower has a width that is less than a full width of the belt.

Abstract: A system and method of cleaning an imprinting fabric used to make bath tissue, paper towel, or facial tissue, in which the imprinting fabric is washed with water from high pressure impact showers and flooding showers, and water remaining on the imprinting fabric after the step of washing is removed with a vacuum roll on a sheet side of the imprinting fabric. The system and method does not involve removing water from the fabric with a uhle box on the sheet side of the imprinting fabric.

Abstract: A papermaking machine air foil including a housing having a top surface, a bottom surface, side surfaces, a leading edge and a trailing edge, at least one air inlet on the top surface that directs injected air into the housing, and an air slot formed in the bottom surface that directs ejected air from the housing towards a trailing edge of the air foil, the air slot having a V-shape. The papermaking machine air foil is configured to be disposed on top of a paper web at a position adjacent to a Yankee dryer so that the ejected air directed by the air slot of the air foil stabilizes the paper web as the paper web is removed from the Yankee dryer.
