  • Patent number: 11920225
    Abstract: Elements formed from magnetic materials and their methods of manufacture are presented. Magnetic materials include a magnetic alloy material, such as, for example, an Fe-Co alloy material (e.g., the Fe-Co-V alloy Hiperco-50(R)). The magnetic alloy materials may comprise a powdered material suitable for use in additive manufacturing techniques, such as, for example direct energy deposition or laser powder bed fusion. Manufacturing techniques include the use of variable deposition time and energy to control the magnetic and structural properties of the materials by altering the microstructure and residual stresses within the material. Manufacturing techniques also include post deposition processing, such as, for example, machining and heat treating. Heat treating may include a multi-step process during which the material is heated, held and then cooled in a series of controlled steps such that a specific history of stored internal energy is created within the material.

  • Patent number: 8540470
    Abstract: A nut fastener is provided for locking the nut to prevent inadvertent loosening of the nut. The nut fastener is particularly useful for tightening a wheel onto an axle. The nut fastener includes a nut, a collar and a retaining ring. The nut is unlocked by pushing on an engagement surface of the collar. When the collar is released, the collar locks against the nut.

  • Patent number: 6178956
    Abstract: An automotive fluid control system with pressure balanced solenoid valve [24] and fluid mixing housing [22] is disclosed. The solenoid valve [24] is preferably used in an EGR (exhaust gas circulation) fluid control system, although the valve may be used in other vehicle fluid control systems, such as an engine block cooling liquid control system. A poppet member [84] of an EGR valve is pressured balanced such that only a light spring [170] and armature [88] are needed to control the positioning of the poppet member [84]. Magnetic and inductance sensors [184, 282] are used to accurately determine the position of the poppet member. The fluid mixing housing [22] homogeneously mixes first and second fluids. A portion of a main first fluid flow is funneled off and mixed in the housing [22] with a second fluid prior to being returned to the main fluid flow.
