摘要： The invention relates to an educational measuring and numeration device with which at least one standard measuring unit is associated, said standard measuring unit defining a section on the device. Each section of the device corresponding to a standard measuring unit comprises at least one visual and/or tactile identification means, said means being continuously visible over the section itself, and the visual and/or tactile identification means of adjacent sections are distinct such that each section of the material can be identified in relation to the adjacent section(s).

摘要： Accessory for magnetic construction games which comprise one or more magnetic bars (4) suitable for being mutually joined through ferromagnetic spheres (5) so as to make up a complex structure, which accessory comprises in turn connecting bars (15; 19; 21, 22) and/or ferromagnetic members having a substantially hemispherical (1, 2; 6, 7; 9, 10; 18) and/or spherical (12, 13; 17; 20) shape which are provided with at least one axial hole and are mutually pivoted for rotating in an independent manner around a longitudinal axis (A) by means of at least one pin (3; 14; 23) arranged in this axial hole.

摘要： Apparatus and method for producing a depth illusion of continuous three dimensional objects using the Moire effect is presented. The apparatus includes at least two surfaces separated by a small distance, one of which surfaces is a transparent sheet imprinted with vertical or nearly vertical, line patterns with slowly varying period in a horizontal direction, and the other is imprinted with a color or black and white horizontally almost periodic pattern related to the other surface pattern in such a way that the combination of both patterns produces a Moire pattern that creates a depth illusion in the observer's mind.

摘要： An amusement device comprises a solid cube which may be disassembled into a plurality of blocks (80, 81, 82, 83) of differing geometric shapes wherein each of the geometric shapes is formed from one or more modular units. Each modular unit comprises an isosceles right triangular prism having a triangular face formed by two legs each of which has a length A and which meet at a right angle, and a hypotenuse which has a length B, said modular unit having a depth which is equal to A, and a volume which is equal to C. Each of the differing geometric shapes is formed from one or more modular units and has a volume equal to an integral number times C, and the total volume of said solid cube is equal to 16C.

摘要： The principles of geometrical projection can be demonstrated with a drawing aid which preferably can be assembled from a kit of parts and which comprises an elongate base (10) carrying a number of object and image elements which can be set at different positions along the base and in different attitudes. These elements may comprise for example a sighting rod (19), a transparent sheet-form element (17) which defines a picture plane and on which the user draws images, an object (15), and a reflector (18). Perspective, orthographic and oblique projections can be demonstrated with just the one instrument using appropriate slots and holes to mount the elements.
