Abstract: This invention is an astrology chart apparatus operable to readily determine (1) characteristics of any of the twelve houses of astrology; (2) key words relative to any such house; (3) comparison ratings of compatability between any sun sign with another persons's sun sign. The astrology chart apparatus includes a central base means having first and second plate means rotatably connected to the central base means by a fastening means. The central base means has central plate indicia means with astrology information that can be viewed outside the outer periphery of first and second plate means plus through cut-out window means therein. Additionally, the first and second plate means are provided with plate indicia means thereon of an astrology nature which can be viewed separately or in conjunction with the central plate indicia means. The window means on the first and second plate means permit comparison of certain astrology information on the central base means and the respective first and second plate means.

Abstract: A device for displaying indicia is provided comprising:(a) at least one cover member having at least one visual display means on at least one surface thereof; and(b) at least one display member slidably movable by gravity with respect to at least one of said cover members within a predetermined area underlying said cover member, said display member having at least one prepositioned indicium on at least one surface thereof, said indicium registering with at least one of said visual display means, whereby said display member slidably changes position with respect to said cover member under the force of gravity in response to rotation of said device in a substantially vertical plane to change the registry of said indicium with respect to said visual display means.In preferred embodiments of this invention a perpetual and yearly calendar is provided.

Abstract: A display board having a window in which an education exercise unit or task is presented for viewing on a removable plate. Front and rear panels enclose a rotatable disk containing radially arrayed pockets for carrying stacks of removable task plates individually into registry with the front panel window. Each pocket is adapted to maintain a plurality of task plates in tiers. Retaining rings concentric with the axis of rotation of the disk, mounted on the inner face of the front panel, and of successively greater diameter and lesser height, are arranged to be engaged with detents on the removable task plates. A slot in the margin of the front and rear panels in radial alignment with the viewing window, enables a handle on the task plates to be grasped individually for release of their detents and withdrawal from the disk pockets. The task plates, as tokens of achievement by the student, can be accumulated on display racks on the front face of the board.
