Abstract: Noble plated tungsten corona wire for copy machine or xerography technology machines and method of securing terminal connectors to the ends of the noble plated tungsten corona wire. The terminal or crimping tab have compound radii to provide for a solid-state diffusion weld and to prevent stress at a junction of the wire and the terminal or the crimping tab.
Abstract: Solenoid for use in harsh difficult environmental conditions for actuation in a pulling motion along a straight line where the magnetic core travels within a stainless steel non-magnetic sleeve. The core uses a plurality of broad Teflon rings fitted in broad annular grooves to reduce friction and wear along its path of travel, to reduce cross-section tangential point to point contact wear, and to prevent sacrificial corrosion of the moveable magnetic core or sleeve due to galvanic action when moisture is present. The core is zinc coated and the sleeve is stainless steel for the prevention of corrosion and rust in order to ensure a smooth and contaminant free inner surface for proper and unhampered movement of the core. Annular Teflon bearings are utilized, as moisture will not cause the Teflon bearing to freeze in low temperature applications.
