  • Patent number: 8109515
    Abstract: A puzzle formed by splitting of a 3-D body by three pairs of symmetrical conical surfaces. The body has a hollow sphere inside with three main axes coincided with the axes of each pair. The elements are a result of splitting by the conical surfaces and comprise outer and inner junction means providing two adjacent elements sliding with respect to each other. There are three types of elements with orientation means: six polar, twelve median and eight triangular elements. The elements adjacent to one conical surface comprise key open means providing elements move apart. The goal of the three-dimensional puzzle is to put the body in right order by 90 degrees rotations of elements spaced from one side of conical surfaces, to the initial ordered orientation, where the body can be separated for two parts providing access to the space located inside the hollow sphere.

  • Patent number: 7623013
    Abstract: An electromagnetic moving system comprises a stator, a moving body and a controller. The stator comprises a circuit board with two layers of electrically connected coil windings spaced apart in a series way and made as spirals with center and peripheral points. The spirals of one layer are shifted in respect to the spirals of the adjacent layer along the line connecting the center points thus the center points of the spirals of one layer in transparent view are located between two nearest spirals of the adjacent layer. Each of the spirals of one layer in transparent view at least partially overlaps two nearest spirals of the adjacent layer. The moving body is comprised of one permanent magnet such as to cause interaction with the stator when it is powered, thus creating a force tending to propel the moving body along the line connecting said center points.
