  • Spring-Based Disc Brake Pad Cushions
    Publication number: 20160108978
    Abstract: Cushions for disc brake pads are disposed between the brake pads and their caliper pistons or caliper fingers. The cushions possess such characteristics of resilience that, during braking action, brake pads follow irregularities and ride over high spots on rotor faces. This action significantly reduces uneven frictional drag, which lowers braking temperature increasing braking efficiency and brake system longevity. Each cushion comprises a resilient body which is further comprised of either a material, such as an elastomeric pad, or a structure such as a compressible spring or other apparatus.

  • Solenoid closure detection
    Patent number: 5053911
    Abstract: A method and apparatus for electronically detecting when a solenoid has closed, or nearly closed, indirectly senses changes in the inductance of the solenoid's coil as the solenoid closes. When the inductance has changed by a selected amount, the solenoid is assumed to have closed, or nearly closed, and current through the coil is promptly reduced. Preferably, changes in the inductance of the coil are sensed by establishing a plurality of current peaks in the coil, and sensing the current's decay time between peaks. When the decay time of a measured current peak exceeds the decay time of a previously measured current peak by a selected amount, it is assumed that the solenoid has closed, or nearly closed.

  • High-precision, fine-detail forging process
    Patent number: 4040286
    Abstract: High-precision, fine-detail forgings are formed from a workpiece material having superplastic forming characteristics by utilizing high strain rate forming to impart the bulk of the total deformation required and superplastic relatively low strain rate forming to impart detail and approach final tolerances in the product.
