Inventor: KANDA SHINJI
IPC: G06V10/48
Filed: 1992-10-02
Abstract: A method for determining an orientation of a line segment in a contour in a local area of a binary contour image. The number of pixels having a predetermined value and located in each orientation in the local area, is obtained, and it is determined that a line segment exists in an orientation in which the number of pixels is large. Further, when it is determined that the number of pixels located in each of a plurality of orientations and having a predetermined value, is greater than a sum of the numbers of pixels in orientations adjacent to said each orientation on both sides thereof, it is determined that a line segment exists in said each orientation. Two orientations in which large numbers of pixels are located are detected, and it is determined whether the point is a constituent of a line segment, a line segment of the sub-straight-line form, or a near-corner point, depending on angles made by the two orientations is equal to 180°, or a difference of the angles made by the two orientations from 180°. Contiguously arrayed pixels in the same orientation are detected as a line segment. A position and an orientation are obtained from points near a corner, and representative values of the positions and orientations of contiguously arrayed near-corner points are determined. (Fig. 3)

Title: Method of recycling scrap metal
Inventor: KAUFMAN SYDNEY M
IPC: B22F1/00
Filed: 1992-01-31
Abstract: A method of embrittling cleaned steel particles is described, followed by a grinding and sorting operation. Depending on the initial carbon content of the steel scrap, a reducing and carbon-containing atmosphere may be provided to carburize the particles as they are being embrittled. A quenching operation is provided at the end of the process to embrittle the particles and before the particles are ground. The ground grit which is produced may then be sorted by size and used as an abrasive compound, or, alternatively may be further ground and annealed in a subsequent operation to provide suitable powder for forming sintered parts. Prior to annealing the grit may be further ground in a partial oxidizing atmosphere to preoxidize the powder, in order to provide oxygen directly within the powder to react with any residual carbon so that the carbon monoxide gas can be formed and the powder can be substantially free of both carbon and oxides when the reaction is complete. Alternatively, the powder may be preheated in a controlled atmosphere prior to annealing to preoxidize the powder.
