lec Electric induction heating of a rail head with non-uniform longitudinal temperature distribution By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT Apparatus and method are provided for making the longitudinal temperature distribution of the bulbous end of a longitudinally oriented workpiece, such as a rail's head, generally uniform when the head has a non-uniform longitudinal temperature distribution. A combination of crown and skirt electric inductors is used to achieve the generally uniform temperature distribution by modulating the magnetic field intensity produced by current flow through one or more of the combination of crown and skirt inductors as required for the non-uniformly heated regions of the rail's head.

lec Conformal anti-reflective coating By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT In one aspect, a method is disclosed that includes providing a substrate having a topography that comprises a relief and providing an anti-reflective film conformally over the substrate using a molecular layer deposition step. The anti-reflective film may be formed of a compound selected from the group consisting of: (i) an organic compound chemically bound to an inorganic compound, where one of the organic compound and the inorganic compound is bound to the substrate and where the organic compound absorbs light at at least one wavelength selected in the range 150-500 nm, or (ii) a monodisperse organic compound absorbing light at at least one wavelength selected in the range 150-500 nm. The method further includes providing a photoresist layer on the anti-reflective film. Full Article
lec Manufacturing method of grain-oriented electrical steel sheet By www.freepatentsonline.com Published On :: Tue, 01 Mar 2016 08:00:00 EST A predetermined steel containing Te: 0.0005 mass % to 0.0050 mass % is heated to 1320° C. or lower to be subjected to hot rolling, and is subjected to annealing, cold rolling, decarburization annealing, and nitridation annealing, and thereby a decarburized nitrided steel sheet is obtained. Further, an annealing separating agent is applied on the surface of the decarburized nitrided steel sheet and finish annealing is performed, and thereby a glass coating film is formed. The N content of the decarburized nitrided steel sheet is set to 0.0150 mass % to 0.0250 mass % and the relationship of 2×[Te]+[N]≦0.0300 mass % is set to be established. Note that [Te] represents the Te content and [N] represents the N content. Full Article
lec Tablecloth retainer By www.freepatentsonline.com Published On :: Tue, 19 Aug 2014 08:00:00 EDT A tablecloth retainer includes an elastic band having at least a primary thickness, a width, and a predesigned boundary, wherein the elastic band is stretched around the perimeter edge of a table top to retain a tablecloth, the predesigned boundary being smaller than a range of table top perimeters accommodating the band by virtue of elasticity of the band.
