Disclosed herein is an electrolytic brush assembly comprising a handle assembly; a shroud extending from the handle assembly, the shroud having an aperture at a distal end thereof; a brush connecting assembly for releasably connecting a brush to the handle assembly whereby the brush extends through the aperture of the shroud and a fluid delivery assembly. The handle assembly comprises an adjustment sub-assembly for selectively moving the brush connecting assembly and a brush connected thereto relative to the handle assembly and the aperture of the shroud. The fluid delivery assembly delivers electrolytic fluid to the proximity of the brush, optionally under closed loop control.

A gas exchange valve for an internal combustion engine may include a valve stem and a wear resistance improving functional layer. The valve stem may extend in an axial direction and may transition into a valve plate in the axial direction. The functional layer may include nickel and tungsten. The functional layer may be arranged in a coating area on an outer circumference of the valve stem and may at least partially define a sliding surface.

An electrochemical deposition system configured for electrochemical plating of a substrate includes a chamber, an electrode, a plating cup and a controller. The chamber holds a plating bath. The electrode is disposed in the plating bath. The plating cup includes a contact ring. The contact ring includes contacts. The contacts are immersed in the plating bath. The controller is configured to apply a voltage signal across the contact ring and the electrode to remove residual from the contacts. The voltage signal includes a plating-de-plating waveform. The plating-de-plating waveform includes multiple cycles. Each of the cycles includes a pair of pulses with different polarity.

The present invention relates to systems and methods for cleaning materials, such as flooring and upholstery. In some cases, the systems and methods use an electrolytic cell to electrolyze a solution comprising sodium carbonate, sodium bicarbonate, sodium acetate, sodium percarbonate, potassium carbonate, potassium bicarbonate, and/or any other suitable chemical to generate electrolyzed alkaline water and/or electrolyzed oxidizing water. In some cases, the cell comprises a recirculation loop that recirculates anolyte through an anode compartment of the cell. In some cases, the cell further comprises a senor and a processor, where the processor is configured to automatically change an operation of the cell, based on a reading from the sensor. In some cases, a fluid flows past a magnet before entering the cell. In some additional cases, fluid from the cell is conditioned by being split into multiple conduits that run in proximity to each other. Additional implementations are described.

The described systems and methods relate to systems for providing a cleaning solution comprising electrolyzed water. While the cleaning systems can comprise any suitable component, in some cases, they include an electrolytic cell and at least one fluid conditioning system that includes a first conduit and a second conduit that are coupled together and are non-concentric with each other. While the fluid conditioning system can be disposed in any suitable location with respect to the cell, in some cases, the fluid condition system is disposed upstream of the cell to provide fluid that passes through the first and second conduits into the cell. In some cases, the fluid conditioning system is disposed downstream of the cell to receive an electrolyzed water produced by the cell. In some cases, the fluid conditioning system is configured to recirculate electrolyzed oxidizing water through an anode compartment of the cell. Other implementations are described.
