A method for manufacturing a hot-dip metal plated steel strip having a plated layer formed on the outer surface thereof includes continuously immersing a steel strip in a bath tub that accommodates a molten metal plating bath, causing a sink roll disposed in the bath tub to change the traveling direction of the steel strip, then causing the steel strip to pass through two support rolls formed of a stabilizing roll and a correcting roll disposed above the sink roll but below the surface of the plating bath, and extracting the steel strip out of the bath. A flow regulation plate is disposed so as to cover at least the upper side of a roll body of the stabilizing roll out of the support rolls with a gap between the flow regulation plate and the stabilizing roll, and the flow of the molten metal plating bath directed toward a portion of the steel strip located from the exit of the support rolls to the surface of the plating bath is led toward the lower side of the stabilizing roll via the gap.

Analyte sensors and methods of manufacturing same are provided, including analyte sensors comprising multi-axis flexibility. For example, a multi-electrode sensor system 800 comprising two working electrodes and at least one reference/counter electrode is provided. The sensor system 800 comprises first and second elongated bodies E1, E2, each formed of a conductive core or of a core with a conductive layer deposited thereon, insulating layer 810 that separates the conductive layer 820 from the elongated body, a membrane layer deposited on top of the elongated bodies E1, E2, and working electrodes 802′, 802″ formed by removing portions of the conductive layer 820 and the insulating layer 810, thereby exposing electroactive surface of the elongated bodies E1, E2.

A hot dip coating device to provide a metal coating on a moving metal sheet, containing a liquid bath of metal coating material in use. The metal coating material on the moving metal sheet in use, including a container for the liquid bath, a guide or sink roll in the container below liquid bath surface level in use to guide the moving metal sheet through the bath, and a gas knife, above the liquid bath in use, having an outlet to project wiping gas on the metal coating on the metal sheet. At least one supporting roll with the guide or sink roll in use influence metal sheet shape in its width direction at the gas knife location. The one supporting roll is above liquid bath surface level to operate on the metal sheet before the metal sheet enters the bath. A method for use of the device.

A continuous coating line includes a snout assembly exposed to molten metal. The snout assembly includes a snout tip positioned about a steel strip that is immersible in the molten metal to provide a seal around the steel strip during entry into the molten metal. The snout tip includes a refractory material that is resistant to wear, abrasion, and corrosion when the snout tip is exposed to the molten metal.
