Patents by Inventor Siddhartha Gaur

Siddhartha Gaur 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).

  • Publication number: 20040197259
    Abstract: A carbonaceous material, also referred to as a carbon alloy, and a process of making the carbonaceous material is provided. A particulate of partially pyrolyzed carbon (PPC) base is formed on heating a carbon-containing feed material and a nucleating agent in the form of a interactive filler is included. The nucleating agent is adhered together to the PPC particles by application of heat.
    Type: Application

  • Patent number: 6382423
    Abstract: A method for processing a mass of solid fine particles including Naturally Occurring Radioactive Material (“NORM”) is disclosed. In one embodiment, the material is sampled and classified into fractions based upon one or more selected criteria such as particle size or particle density. The level of radioactivity associated with each fraction is determined, leading to separation of the mass of fines into selected fractions based upon one or more selected criteria and the activity levels of the fractions. Selected fractions are chosen for chemical treatment, thereby reducing the volume of material to be treated. By reducing the volume of solid material to be treated, the amount of chemicals used for treatment is reduced, along with the size and capacity of the processing equipment required to treat the material.
