20150204918 | MAGNETIZING INRUSH CURRENT DETECTION METHOD, MAGNETIZING INRUSH CURRENT RESTRAINT METHOD AND DEVICE - A method for detecting a magnetizing inrush current of a transformer includes the steps of obtaining a difference current for each AC phase of a transformer and calculating, for each AC phase, at least two factors for waveform symmetry recognition, on the basis of the difference currents obtained within one period. For each type of factor, one obtains the maximum value of the three factors corresponding to the three AC phases, to serve as a maximum phase factor of that factor. Based on the maximum phase factor obtained, a waveform symmetry recognition algorithm is used to calculate a corresponding waveform symmetry parameter, and if the waveform symmetry parameter meets a requirement for waveform asymmetry, then it is determined that a magnetizing inrush current has occurred. A device for protecting the transformer is further provided. | 07-23-2015 |

20160082525 | MULTI-EDGE DRILL BIT - A multi-edge drill bit includes a drill body and a drill tip at one end of the drill body. The drill tip includes two main cutting edges extending to outside and symmetric about a center of the drill body and two crescent grooves symmetric about the center. Each of the crescent grooves intersects with corresponding main cutting edge respectively to divide the main cutting edge into an outer edge, an arc edge, and an inner edge. A transverse edge is formed between the two inner edges and has its middle point forming the core bit. The outer edges intersect with said arc edges to form two symmetric side bits. A ratio of the vertical distance between the core bit and the side bit to drill diameter is 0.02 to 0.03 and a ratio of the transverse edge length to drill diameter is 0.05 to 0.08. The drill bit as described herein provides a stable centering effect during drilling and facilitates continuous stable drilling in round pipe and thin plate applications. | 03-24-2016 |

Combined with the telecentric imaging system, the time between the two exposures are adaptive and can be adjusted according to the velocity of precipitation particles. The size and shape can be obtained by the images of particles; the fall velocity can be calculated by particle displacement in the double-exposure image and interval time; the drop size distribution and velocity distribution, precipitation intensity, and accumulated precipitation amount can be calculated by time integration. This invention provides a method for measuring the shape, size, velocity, and other microphysical characteristics of various precipitation particles. | 02-05-2015 |
