  • Patent number: 7377661
    Abstract: The invention provides a method and arrangement for illuminating an under mount sink disposed subjacent a counter. A light source is disposed below a top surface of the counter and proximate to the under mount sink. The under mount sink is affixed to the underside of the counter and power is supplied to the light source. The under mount sink is illuminated by the light source when the power source is activated. The invention also provides a device that may be used for illuminating an under mount sink, while keeping the light source from contact with water.

  • Patent number: 6860293
    Abstract: A variable pressure solenoid (VPS) control valve. The VPS control valve includes an hydraulic section and a magnetic section. The hydraulic section includes a movable valve that receives a pressurized fluid and generates a control pressure, and the magnetic section controls the operation of the movable valve. The movable valve includes an inlet ball valve for limiting the flow of pressurized fluid into the hydraulic section and an exhaust valve for limiting the exhaust of pressurized fluid out of the hydraulic section. The magnetic section includes a spring-biased armature, and an electromagnetic coil for generating a variable electromagnetic field in response to an electrical input signal for moving the spring biased armature.

  • Patent number: 6520044
    Abstract: A shock absorber for coupling a brake pedal lever arm to a brake booster push rod. The application of impact forces to the brake booster push rod is sensed and the brake pedal lever arm is no longer rigidly coupled to a brake booster push rod. The impact forces applied to the brake booster push rod are then absorbed by the shock absorber. Finally, after the cessation of the impact forces, the brake pedal lever arm is once again rigidly coupled to the brake booster push rod.
