Patent number: 9404263Abstract: A roofing material comprising an upper surface and a lower surface, wherein the upper surface includes reduced-particle size granules and may further include a reduced-thickness face coating. The thickness of the upper surface is related to the particle size of the granules deposed on the face coating. A smaller particle size granule than those used in traditional roofing shingles is utilized in the upper surface which may allow for a reduced-thickness face coating while not sacrificing the retention of the granules on the surface of the roofing material or desired physical characteristics. The face coating may include a reduced amount of filler material, such as mineral fillers, than face coatings of traditional roofing materials.Type: GrantFiled: July 12, 2010Date of Patent: August 2, 2016Assignee: Building Materials Investment CorporationInventors: Matti Kiik, Tommy F. Rodrigues, Sudhir B. Railkar, Adem Chich

Patent number: 9290945Abstract: The present disclosure relates, in some embodiments, to systems, articles, materials, and methods for roofing a structure including, for example, hybrid shingles comprising a first material and a second material. A hybrid shingle may comprise, in some embodiments, a first layer comprising a metallic substrate or a polymeric substrate and at least partially defining a headlap region of the shingle, a buttlap region of the shingle comprising one or more tabs interspersed with inter-tab openings, an outward-facing surface of the first layer, and a substrate-facing surface of the first layer; and a second layer comprising a base and asphalt, having a smaller area than the first layer, and at least partially defining a buttlap region of the shingle, wherein the second layer is fixed to the substrate-facing surface of the first layer.Type: GrantFiled: January 28, 2014Date of Patent: March 22, 2016Assignee: BUILDING MATERIALS INVESTMENT CORPORATIONInventors: Margie A. Beerer, Matti Kiik, Sudhir B. Railkar

Patent number: 9133621Abstract: A universal inside corner patch for patching inside corners formed by protrusions from a commercial low slope roof is disclosed. The universal inside corner patch includes a body having a central portion and a peripheral portion. A cutout is formed in the body extending from the peripheral portion to the central portion thereof. The cutout defines in the body a skirt having an edge on one side of the cutout and a flap having an edge on an opposite side of the cutout. Folding locations such as lines or other indicia on the body correspond to respective angles of an inside corner to be patched. When the skirt portion is overlapped with the flap portion with the edge of the skirt portion registering with one of the folding locations, the inside corner patch is configured to conform to an inside corner with an angle corresponding to the one of the folding locations. An adhesive may be disposed on a back surface of the body for adhering and sealing the corner patch in place.Type: GrantFiled: December 18, 2013Date of Patent: September 15, 2015Assignee: Building Materials Investment CorporationInventors: Sudhir B. Railkar, Lynn G. Picone, Brian Duffy, Dave Scott, Li-Ying Yang

Patent number: 5391929Abstract: The method of power transmission and distribution aims to mitigate the magnetic fields generated at a right of way and at distances which extend beyond the right of way. The transmission and distribution lines use various line parameters including the relative locations of the conductors around the axis of symmetry of the right of way, the current magnitudes and the phase angles of the currents flowing in the conductors in optimum asymmetric fashion. The use of magnetic field mitigation bodies placed adjacent to the current bearing conductors increases the scope and the effectiveness of the mitigation. A mitigation technique is also provided for mitigating the magnetic field generated by current bearing sources used in power distribution, with unknown or difficult to characterize current distributions, such as transformers.Type: GrantFiled: May 17, 1993Date of Patent: February 21, 1995Assignee: Stevens Institute of TechnologyInventors: Dilhan M. Kalyon, Halit S. Gokturk, Sudhir B. Railkar

Patent number: 5365115Abstract: A method and apparatus for mitigation of magnetic fields from magnetic field sources operating at low frequencies, typically less than 100 KHZ, are provided. The method is based on placing magnetic bodies of proper shape, size and physical properties close to the source of the magnetic field to cancel or reduce the magnetic field at desired sites, located away from the source. The method is applicable to mitigating all sources of magnetic fields including those generated by electric power lines, transformers, various tools, electronic devices and appliances. The apparatus, an application of the method to electric power transmission lines, consists of body of magnetic material disposed adjacent to at least one conductor of a multi-line electric power transmission system.Type: GrantFiled: June 23, 1992Date of Patent: November 15, 1994Assignee: Stevens Institute of TechnologyInventors: Dilhan M. Kalyon, Halit S. Gokturk, Sudhir B. Railkar
