Abstract: A micro-alloyed copper powder was produced using gas atomization reaction synthesis, with the alloy preferably comprising Cu-0.3Zr-0.15Ag wt. %. The novel copper alloy improves the manufacturability of copper in powder bed fusion manufacturing processes by minimizing or avoiding the prior art problems associated with oxidation of the copper precursor used in additive manufacturing. Advantageously, the provided copper alloy powder maintains the high electrical conductivity of copper while addressing the prior art oxidation issue.

Abstract: A rotatable magic picture ball comprises a ball assembly comprising an upper section including four upper units and a lower section including four lower units wherein each unit occupies one eighth of a sphere and is rotatable, and each lower unit comprises a bottom cavity; a base assembly comprising four sectors each occupying about a quarter of a cylinder and a central recessed portion including two vertical sleeves and two horizontal sleeves, each sleeve having two channels for rotatably coupling the sectors together; eight half-circular stickers and two circular stickers adhered to inner surfaces of the units so that the units can turn each other; and an interior magnet on each upper unit so that two adjacent upper units can be magnetically secured together. A variety of shapes and colorful patterns for advertisement can be formed by the stickers having predetermined patterns and/or the ball assembly having a predetermined pattern.

Abstract: A shape-shifting game can. The game can includes upper and lower cylindrical blocks superimposed on each other. Each of the cylindrical blocks are quartered to form a total of eight fan-shaped columns and each of the fan-shaped columns comprise upper and lower fan-shaped surfaces, a circumferential surface and a pair of square surfaces. The lower fan-shaped surfaces of the upper cylindrical block and the upper fan-shaped surfaces of the lower cylindrical block are connected with fan-shaped stickers. Pairs of the upper fan-shaped surfaces of the upper cylindrical block and pairs of the lower fan-shaped surfaces of the lower cylindrical block are connected with hemi-cycle patterned stickers. The square surfaces of the fan-shaped columns are connected with double-block stickers. The circumferential surfaces of the cylindrical blocks are connected with four fan-shaped column stickers and two hemi-cycle column stickers respectively.

Abstract: This invention is a kind of magic can, which is consisted by 8 fan-shaped columns and forms 16 fan-shaped surfaces pasted with 8 fan-shaped patterned stickers, 16 square surfaces pasted with 8 double-block stickers, 8 surfaces of circumference pasted with four fan-shaped column sticker and 2 hemi-cycle stickers. A sticker may be pasted on 2 surfaces so these 8 fan-shaped columns can be linked together and turned to present various kinds of styles like magic. It offers the entertainment of brainstorming and can also improve the visual effect to reach the promotion purpose. In addition to the entertainment, it can also be used as a card clip or other stationery.
