ac Method of manufacturing corrugated preform using braiding process By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT A method of manufacturing a corrugated preform that allows a fiber volume fraction and an orientation angle to be substantially the same at a concave portion and at a convex portion when the corrugated preform is manufactured based on a braiding process. The method includes braiding a composite material corresponding to an outer diameter of a cylindrical cylinder shape, braiding the composite material by connecting a plurality of separate composite materials to one side of the braided composite material, and braiding the composite material to one side of the separate composite material corresponding to the outer diameter of the cylindrical cylinder shape.

ac Device for automatically controlling signals and multiple trans traveling on the same track By www.freepatentsonline.com Published On :: Tue, 03 Feb 2015 08:00:00 EST An electrical device not only controls train signals as trains advance, but also alters the voltage in the tracks leading up to the signals so that the trains will actually stop at a red signal, slow at an amber aspect and continue on at full speed when the signal is showing green. The electrical device of the present invention can change the “block signal” from “green” to “red”, thereby signaling the engineer behind the train to come to a stop. In addition, the electrical device can simultaneously change the voltage in the tracks to stop the approaching train at the red signal. Only when the forward train has cleared will the approaching train get a clear signal and voltage to resume its forward progress. Full Article
ac Method to replace an instrument case and replacement case therefor By www.freepatentsonline.com Published On :: Tue, 10 Feb 2015 08:00:00 EST A method designed to replace a compromised instrument case with a new case without the need to disconnect any wire, relay or any other electric equipment is described herein. The instrument panel is supported for example by a temporary support frame during the dismantling of the old case and the assembly of the new case. The new case is therefore assembled on site around the instrument panel. The new instrument case includes a floor which is made of at least two parts, one on each side of the wiring. The instrument case therefore remains in a normal working mode during the entire replacement procedure thus preventing downtime. As well, the amount of manpower required for the replacement of an instrument case is drastically reduced. Full Article
ac Interactive digital drawing and physical realization By www.freepatentsonline.com Published On :: Tue, 17 Mar 2015 08:00:00 EDT A system and method for interactively producing a 3D representation of a vector graphic is disclosed. A vector graphic representing a 2D graphic having a number of endpoints joined by vector segments is automatically or interactively converted into a triangulated mesh in a form readable by a 3D printer. The conversion from vector graphic to a triangulated mesh is accomplished by generating an n-sided polygon in the vicinity of each endpoint of the vector graphic. Each of the vertices of the polygon are then be joined by a line to a corresponding vertex on the next adjacent polygon. Each vertex is also joined to an adjacent vertex on the next adjacent polygon. The process is continued until all polygons are joined, resulting in a triangulated mesh, which is then converted into a format readable by a 3D printer and sent to a 3D printer to produce the 3D representation.
