Abstract: The globe-shaped clock for a city square includes a base for placement on a select public location in a town or city. The base includes a plurality of pointer rods radiating in both major and minor geographic directions. A spherical cage is mounted to the base, and the cage surrounds a rotating globe therein. The cage is topped by a clock spire having a frustoconical base and a plurality of major and minor pointer rods radiating towards both major and minor geographic directions. A plurality of illuminated, curved, longitude lines defines the spherical cage. The longitude lines illuminate sequentially in varying intensity depending on the time of day. An electronic control unit is provided to define the pattern of illumination. A plurality of display units surrounds the base in line with each longitude line and displays different time zones.

Abstract: Disclosed is a globe apparatus for showing rotation and revolution at the same time. The globe apparatus includes: a base to which one end of at least one support rod is fixed and one end of a revolution axis is rotatably fixed; a support arm fixedly coupled with the support rod; an Earth globe rotatably coupled with the support arm at two confronting points of the Earth globe with an inclination, and rotating; and a revolution unit placed inside the Earth globe and revolving relative to the two confronting points with coupled with the revolution axis, and showing day and night separately according to the rotation of the Earth globe.

Abstract: A spherical world globe with geographic features imprinted on its surface rotates on an axis through the poles. The sphere is not large enough to carry legible details of all areas. Greater details are stored in a memory such as a compact disc. An indicator on the sphere is positionable north and south or the sphere is positionable relative to a fixed indicator to position the indicator along a north/south meridian. A sensor senses the north/south position of the indicator and sends a signal to a control circuit connected to the memory. Another sensor connected to the rotation of the sphere sends an east/west signal to the control circuit. Using the two signals, the circuit finds the area corresponding to the area selected on the sphere in the memory and displays it on a display in greater detail than is visible on the sphere.

Abstract: A spherical world globe with geographic features imprinted on its surface rotates on and axis through the poles. The sphere is not large enough to carry legible details of all areas. Greater details are stored in a memory such as a compact disc. An indicator on the sphere slides north and south. A sensor senses the north south position of the indicator and sends a signal to a selection circuit connected to the memory. Another sensor connected to the rotation of the sphere sends an east/west signal to the memory. Using the two signals, the circuit find the area corresponding to the area selected on the sphere and displays it on a display in greater detail than is visible on the sphere.

Abstract: The present invention comprises an educational device for use with an earth globe having ecliptic angle of inclination for teaching students the position of the earth relative to the sun through the various seasons. The educational device can also be used to teach the months of the year as well as teaching the causes of night and day. The educational device having a flat board, which represents the earth's orbital plane, and having a sun label, a plurality of season labels and a plurality of month labels affixed on the facade of the board. The educational device also has a indexer wheel pivotally mounted to the board for rotatably mounting the earth globe so that the student may be able to freely rotatably maneuver the earth globe relative to the season labels so that the student can visually grasp the causes of the seasons as the year proceeds.

Abstract: Disclosed herein is a constellatory observation assisting apparatus. The apparatus is equipped with a time information acquisition section for acquiring data information on a specific time, a positional information acquisition section for acquiring positional information on a position on the earth, and a heading acquisition section for acquiring heading information on an constellatory observation heading. The apparatus is also equipped with a storage section for storing star chart data, and a control section for reading out constellation image data, which is seen at the specific time and position and in the heading, from the star chart data, based on the time information, the positional information, and the heading information. The apparatus is further equipped with a display unit for displaying the constellation image data read out by the control section.

Abstract: A model globe for illustrating time relationships and related concepts includes a global representation of the earth rotatable about an axis simulating the earth's axis of rotation. A cursor assembly is independently rotatable about the axis, and includes a cursor which may be positioned at a desired place on the earth as represented on the model globe. An indicator is coupled to the cursor assembly and displays the rotations position of the cursor about the simulated axis of rotation. The indicator is preferably in the form of a clock, whereby the time over a 24-hour period corresponding to a revolution of the earth about its axis is displayed to correspond to the position of the cursor. The cursor assembly may be locked to the globe so that they may be rotated about the axis in unison, whereby the indicator depicts the passage of time along the longitude of the cursor as the globe rotates.

Abstract: An electrically driven, world globe displaying Greenwich time, clock time, week of the year, season of the year and daylight-nighttime of a particular geographic location and a particular time of day relative to the rest of the world comprising a globe displaying a geographic arrangement of the world, a Greenwich time zone dial fixedly attached to said globe displaying Greenwich time relative to longitudinal locations of the geographic arrangement of the world, said globe and said Greenwich time zone dial together rotating in a first direction one revolution every twenty-four hours, a clock time zone dial rotating in a second direction opposite to said first direction, rotating one revolution once every twenty-four hours, a stationary geographic zone dial indicating cities and countries of the world.

Abstract: A device for controlling the direction of rotation of a world globe. The device has a ratchet ring which is affixed to the globe near the North or South Pole thereof. A deflectable pawl member is held by the support frame of the globe and permits the globe to rotate only so that its surface moves eastwardly.

Abstract: An earth planet model as illustrated in the drawings having a base supporting a globe cradle 28. The globe cradle supports a glove 40 at a north pole bearing 48 and at a south pole bearing 50 with the polar axis of the globe being inclined. The model 10 has a polar shaft 66 with a north pole shaft end 68 extending upward through the north pole bearing 48 and a south pole bearing end 70 extending downward through the south pole bearing 50. A light illuminating means is tiltably mounted on the polar shaft 66 for tilting movement and for rotation with the shaft for illuminating the interior of the globe. The model 10 has a manual adjusting means associated with the north pole bearing 48 for manually adjusting the inclination of the illuminating means in response to the setting of a manual knob. A timer drive is detachably coupled to the south pole shaft end 70 for rotating the polar shaft with respect to the globe. The timer is removably mounted on the base.
