Patents by Inventor Mahmud Keschwari

Mahmud Keschwari has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10000220
    Abstract: A brake caliper for a disk brake or to a disk brake with a brake caliper for rail vehicles. A brake caliper has caliper arms at which at the ends brake shoes are mounted and which are pivotally driven against each other by a brake cylinder. The brake caliper or disk brake has the advantage that the brake cylinder and the wear adjusting device are contained in a common housing and that the wear adjusting device acts along the same linear axis of movement as the force which is generated between two carriers which are pivotally connected to the caliper arms and drive the same for pivoting in order to subject the brake shoes to tension against each other.

  • Patent number: 5585711
    Abstract: A method of producing electrical energy from rotary motion of an axle of a vehicle utilizes a generator assembly including a generator coupled to the axle. The method includes determining the rate of rotation of the axle, carrying out the electrical energy production as well as the determination of the rate of rotation exclusively through the generator, and evaluating pulse parameters of each induced electrical voltage pattern for the determination of the rate of rotation. The generator assembly includes a rotor coupled to the axle and permanent magnets mounted on the rotor distributed over the circumference thereof. The permanent magnets have radially extending polar axes. A stator includes induction coils mounted coaxially around the circumference of the rotor. An air gap is defined between the stator and the rotor.

  • Patent number: 5419620
    Abstract: A device for adjusting the braking force in railborne vehicles, for trains combining railborne vehicles of more recent and older construction. The braking signal, which can be switched pneumatically via a main air line is transmitted to the brake control by a PU converter connected to the main air line rather than transmitting the braking signal via the vehicle bus.
