  • Patent number: 6629709
    Abstract: If the wheel/rail adhesion for a railway vehicle is insufficient then the wheels may slip when braking. If slipping is detected, a control system may reduce the brake pressure to permit a controlled level of slip and so to optimize the braking force for the available adhesion. By determining the pressure supplied to the brake cylinder, a signal may be obtained which indicates the value of the adhesion. Alternatively the adhesion may be monitored by detecting any discrepancy between the braking deceleration demanded by the driver and the observed deceleration. The adhesion signal may activate a warning. It may also be used to adjust the rate at which sand is supplied by a sander to the wheel/rail interface. The rate at which sand is supplied may also be adjusted in accordance with other parameters such as the train speed.

  • Patent number: 5582441
    Abstract: A sand delivery system for use in automobiles, or other vehicles. The device uses the hollow front bumpers found on most modern vehicles today to store bags of sand, which is delivered through a number of nozzles located in the front of the vehicle. A blower system forces the sand through the nozzles and projects the sand in a wide pattern out in front of the vehicle. The system is designed to operate when the vehicle is braking. Because the sand is disbursed out in front of the vehicle, the tires can better utilize the sand for braking. Because the sand is projected out in front of the vehicle only a moderate amount of sand is needed to improve traction, thereby reducing the need for large quantities of sand. The sand delivery system can be tied to a manual switch, the vehicle's brake pedal, or to a computer that is tied into the anti-lock brake systems of a car. In the latter case, sand is only be applied when the anti-lock brake system is activated.
