Patents by Inventor Anand Waman Bhagwat

Anand Waman Bhagwat 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: 7055244
    Abstract: The present invention relates to a method of forming a coil of spring wire by winding a wire into a coil spring formed of a plurality of rings of the wire wherein each of the rings has a substantially constant strain rate. The forming speed of the wire being wound is controlled so that each of the rings has a substantially constant strain rate and minimum work hardening occurs.
    Type: Grant

  • Patent number: 6099797
    Abstract: This invention reveals steel alloys for use in manufacturing reinforcing wires for rubber products, such as tires. The steel filaments made with such steel alloys have an outstanding combination of strength and ductility. The steel alloys of this invention can be manufactured into filaments having a tensile strength in the range of 4000 MPa to 5000 MPa. Additionally, these can be patented in a low-cost process due to their having a very fast rate of isothermal transformation. This allows the steel in the steel wire being patented to transform from a face-centered cubic microstructure to an essentially body-centered cubic microstructure within a very short period. This invention more specifically discloses a steel alloy composition which is particularly suitable for use in manufacturing reinforcing wire for rubber products which consists essentially of (a) iron, (b) about 1.05 to about 1.7 weight percent carbon, (c) about 0.2 to about 0.8 weight percent manganese, (d) about 0.1 to about 0.

  • Patent number: 5873961
    Abstract: This invention discloses a process for producing a high strength filament, said process comprising the steps of: (1) heating a steel wire to a temperature which is within the range of about 850.degree. C. to about 1100.degree. C. for a period of at least about 2 seconds; wherein said steel wire consists essentially of about 96.61 to about 98.905 weight percent iron, from about 0.72 to about 1.04 weight percent carbon, from about 0.3 to about 0.8 weight percent manganese, from about 0.05 to about 0.4 weight percent silicon, from about 0.02 to about 0.3 weight percent copper, and from about 0.005 to about 0.85 weight percent of at least one member selected from the group consisting of chromium, vanadium, nickel and boron, with the proviso that the total amount of silicon, manganese, chromium, vanadium, nickel and boron in the microalloyed high carbon steel is within the range of about 0.7 to 0.
