So that that corrosion-resistant layer has high formability, especially cold formability, and hence significantly improved adhesion on forming, the corrosion-resistant layer may comprises nickel, wherein nickel-containing phases are located at a transition from the corrosion-resistant layer to a base material of the steel sheet. The nickel content of the corrosion resistant layer may be in a range from 5 to 30% by weight. Further, a method for producing a surface-finished steel sheet of this kind is also disclosed. In some examples, a nickel layer may be applied to a steel sheet, preferably cold-rolled thin steel sheet in the form of flat steel product, prior to hot-dip coating the steel sheet with a liquid aluminum melt or with a liquid melt of aluminum-based alloy.

Abstract: An electrostatic spray system has a support for a liquid container, and the high voltage components mounted through isolators for providing electrical insulation relative to a low voltage or grounded support. The liquid container is connected to a pump that provides the liquid under pressure, after an electric charge is applied to the liquid on the exterior of the liquid container. The liquid container has an open top, and a sprinkler head adds liquid to the liquid container. The sprinkler head is mounted on the low voltage support, but all high voltage components are electrically isolated from low voltage components to insure there is little current leakage back to ground.

Abstract: A detent mechanism for a hydraulic control valve, having a detent position in which a detent member is in engagement with a groove and a spring urges the detent member into the groove so that a predetermined force is required to move the detent member out of the groove. A second spring loaded detent member is provided which requires the application of another predetermined force in order to move the mechanism into the detent position. The springs for both of the detent members can be readily changed to adjust the forces required to operate them.
