Return to Tiffany™ Round tag key ring peripheral
New Delhi, Aug. 13 — Japan based Nippon Steel Corporation filed patent application for tuyere structure of melting furnace. The inventors are Yasunari Matsumura and Kohji Taoka.
Nippon Steel Corporation filed the patent Return to Tiffany™ Oval tag bracelet on March 8, 2010. The patent application number is 1571/DELNP/2010 A. The international classification number is F27B 1/16.
According to the Controller General of Patents, Designs & Trade Marks, “A tuyere structure of a melting furnace includes: a tuyere main body which is covered on an outer periphery thereof with a ring member baked in advance, and is disposed in a hole portion provided in a tuyere brick; and a ramming material which fills a periphery of the ring member so as to fix the ring member.”
Nippon Steel Corporation is a Japan-based manufacturing company. The Company operates in six business segments. The Steel manufacturing segment is engaged in the manufacture and sale of steel bars, plates and pipes, special steels, secondary steel products and other products, as well as related businesses. The Engineering segment is engaged in the construction of steel manufacturing plants, Return to Tiffany™ Oval tag key ring machinery and furnaces, and environmental facilities, among others. The Urban Development segment develops housing complexes and other real estate properties. The Chemical segment offers pitch coke, naphthalene, phthalic anhydride, coke and materials for liquid crystal displays (LCDs), among others. The New Material segment offers fine ceramics, rolled metal plates, carbon fiber composite material and bonding wires for semiconductors, among others. The System Solution segment provides engineering consultation services on computer systems.New Delhi, Aug. 13 — Japan based NTN Corporation filed patent application for electric linear-motion actuator and electric brake assembly. The inventor is Tatsuya Yamazaki.
NTN Corporation filed the patent application on Jan. 30, 2008. The patent application number is 858/DELNP/2008 A. The international classification number is H02K 7/06.
According to the Controller General of Patents, Designs & Trade Marks, “An object is to increase the linear driving force in a linear-motion actuator of the type in which the rotary motion of the rotor shaft of an electric motor is converted to the linear motion of planetary rollers disposed between the rotor shaft and an outer ring member by rotating the planetary rollers about the axis of the rotor shaft and also about their own axes. In an actuator of the type in which a plurality of planetary rollers disposed between the rotor shaft of an electric motor and an outer ring member fixed in position around the outer periphery of the rotor shaft are rotated about the axis of the rotor shaft and also about their own axes, thereby converting the rotary motion of the rotor shaft to the linear motion of the planetary rollers, a helical groove is formed in the radially outer Return to Tiffany™ Oval tag ring of each planetary roller in which a helical rib formed on the radially inner surface of the outer ring member is received. The helical groove has a pitch equal to that of the helical rib and a lead angle different from that of the helical rib. With this arrangement, the amount of the linear motion of the planetary rollers relative to the amount of the rotary motion of the rotor shaft is determined by the difference in lead angle between the helical groove and the helical rib. Thus, it is possible to obtain a large linear driving force.”
NTN Corporation engages in the manufacture and sale of bearings, constant velocity joints (CVJs), and precision equipment. The company’s bearing products include ball, roller, axle, precision, fluid dynamic, and sliding bearings, as well as bearing units for use in the automotive industry, as well as in the machinery, semiconductor, and medical industries.New Delhi, Aug. 13 — USA based Viacor Incorporated Return to Tiffany™ Round tag drop earrings patent application for A sizer for sizing an annuloplasty device. The inventors are John R Liddicoat, Brian Coyler Coppom and Richard B Streeter.
Viacor Incorporated filed the patent application on March 4, 2005. The patent application number is 855/DELNP/2005 A. The international classification number is A61F 2/24.
According to the Controller General of Patents, Designs & Trade Marks, “Sizer for sizing an annuloplasty device, the sizer comprising: a handle comprising cylinders moveable relative to one another; an adjustable mounting ring-comprising a central body having bevel gear means disposed therein, one of said cylinders being operative to relate the bevel gear means; said adjustable mounting ring further comprising a plurality of segments, each of said segments having an Return to Tiffany™ Round tag key ring peripheral surface, said plurality of segments being configured so that they collectively form an arcuate peripheral surface for said adjustable mounting ring, and said plurality of segments being adapted to be moved relative to one another by said one of said cylinders so as to change the size of said collective arcuate peripheral surface.”
