Embodiment Construction

[0046] Referring now to the accompanying drawings, the Figure 1a with 1b As shown in , the display device comprises a transparent housing 2 containing a ball 4 floating near the interface 6 of a lighter fluid 8 such as NOPAR 12 and a heavier fluid 10 such as propylene glycol. The ball 4 can be driven into rotation by an internal mechanism, as described below, and preferably has graphic features on its surface, such as those of the globe. The lighter fluid 8 and the heavier fluid 10 are immiscible and are preferably both transparent. The density of the ball 4 is set to be between the density of the lighter fluid 8 and the heavier fluid 10 so that without any mechanical connection to the top inner surface 12 or bottom inner surface 14 of the housing 2 the ball 4 will float.

[0047] The housing or shell 2 is shown as one integral part, but it is in fact formed of at least two parts adapted to surround the ball 4 and bonded together, preferably leaving the bond line 3 invisible...

Abstract

In a display device where a moving object is immersed in a fluid filling a transparent sealed, vessel (72) and is rotated by an internal electrical mechanism that derives it power from a photo cell (128) and its counter torque from an internal compass (140), the index of refraction of the fluid is adjusted by addition of water to match the index of refraction of the vessel material. The formula of the fluid is also tailored to minimize absorption of ambient moisture into the vessel. In one embodiment of the electrical spinning mechanism, the magnet acts both as a biasing compass and as a magnetic field generator for the motor. In a second embodiment of the spinning mechanism, the stator is constituted by a multipole ring-shaped magnet (120) that does not interfere with the operation of the biasing compass magnet (140). Multiple windings in the electrical spinning mechanism are energized through a split-ring and brush commutator (92) that use the mechanism shaft (122) as conductor.

Description

technical field [0001] This invention relates to self-starting and self-driving display devices, and more particularly to spinning spheres driven by radiant energy. Background technique [0002] Various types of novel structures that move without apparent support, drive mechanism, or power input are commonly used as toys, decorative genre paintings, or advertising media. Various examples of such structures have been disclosed in U.S. Patent No. 5,435,086 to Huang et al., Japanese Patent Nos. 10137451, 101431101 and 10171383 to Hirose Mamoru, Japanese Patent Nos. 7210081, 7219426 and 10171383 to Taragi Hiroshi. 7239652 and German Patent Nos. DE19706736 Fushoellier, DE3725723 Steinbrinck and DE41377175 Lang. Recent embodiments have no external connections at all. If they are not firmly fixed to the external support, they require complex and bulky counter-torque generating mechanisms, such as fan blades or other internal bulky and complex systems, which consume a lot of power...
