Abstract: A fabric formed from fiber-like strands of hollow, transparent filaments which have been woven or otherwise joined together is disclosed. The hollow strands contain a liquid in which color-coded micromagnets are dispersed. The micromagnets are free to rotate within the filament, the fabric thereby being capable of changing colors, either selectively or totally, when an activating magnetic force causes the micromagnets therein to rotate. The fabric may incorporate, in place of color-coded micromagnets, other orientable bodies which are also capable of being oriented, as for example by an electromagnetic or electrostatic force field, to produce a visual display. Further, the fabric may comprise a material having one or more liquid filled veins, the liquid again containing color-coded micromagnets or orientable bodies dispersed therein.

Abstract: This invention relates to a hardened transparent sheet comprising a binder and hardened microcapsules, the microcapsules containing viewable color-coded micromagnets rotably dispersed in a liquid so as to be magnetically responsive, the microcapsules being pre-hardened independently of the hardening of the binder in forming the sheet.

Abstract: This invention relates to a process for making microscopic size capsules from an emulsion having an inner oily or hydrophobic phase (material to be encapsulated) and an outer hardenable hydrophilic phase. The process is characterized by the step of contacting said emulsion with a break-up fluid capable of dividing said emulsion into substantially separate capsules having an inner hydrophobic phase and an outer hardenable hydrophilic phase; and then hardening the hydrophilic phase of said capsules to form microscopic size capsules or microencapsulations.The separated capsules can contain clusters of capsules, or they may be made as separate, individual capsules. In the preferred embodiment, the break-up fluid contains a surfactant capable of enhancing the break-up function of the fluid so that the separated capsules are predominately individual capsules.This invention also relates to microscopic size capsules formed by this process.

Abstract: A device adapted to provide a visual display under the influence of an exterior magnetic field which comprises a plurality of rotatable, multi-colored, non-magnetically interactive, permanently magnetized micromagnets disposed in a cavity within a body having a transparent surface and a plurality of relatively small compartments within the cavity. The device is illustrated by a sheet containing such micromagnets between the thin cavity of the front and rear surfaces of the sheet where the relatively even dispersion of the micromagnets in the sheet is maintained by such compartments whose barriers minimize displacement so that physical pressure exerted on the sheet, such as by a twist or flex, does not substantially alter the even dispersion of the micromagnets.
