Abstract:
A multiple international time indicator watch, a watch casing (1), an area indication dial seat (2) installed on a movement (not shown), a circular time indication disc (3) positioned on the upper portion of the area indication dial seat (2) and configured to rotate on the area indication dial seat (2) by means of an hour hand axis (not shown) of the movement, and a bezel (4) installed on the circumferential edge portion of the circular time indication disc (3) in which an arrow mark (7) is indicated on the upper-central portion. Thus, times of 12 areas of a variety of time differences can be simply read at the same time, which provides a simple structure and reduces a production cost.
Abstract:
A territorial globe with a world-wide watch function according to a rotation of the globe. In the globe, a sensor (42) is installed at one end of a rotation axis (14) to detect a rotation amount of the globe. A world-wide time display (44) processes an input information from the sensor (42) using the sensor (42) to display major city (or country) names and a current time and date (i.e., year, month, day, day of the week) in a time zone of the earth corresponding to the rotation amount of the globe. The globe according to the present invention is capable of easily selecting a time zone only with an operation rotating the globe as well as conveniently displaying city (or country) names and a current time and date (i.e., year, month, day, week, etc.) in the selected time zone.
Abstract:
Device for determining the time comprised of the following coaxially arranged elements: an operating rotating disk (1), the face of which bears the representation of a geographical map (2) with the appropriate names and divided into segments by meridians; an annular base (3) bearing points (4) used to indicate the time of day and for alignment with the meridians when determining the time. The representation of the geographical map (2) is a mirror-image projection of the Earth's entire surface as seen from above and from the center of the North Pole.
Abstract:
The invention relates to a rotary mounted piece for a watch/clock drive, with a driving disk. This driving disc is connected to the case by a bearing and is driven by a conventional clock/watch movement. At least one driving ring (3, 5) is situated between the driving disk (1) and the case (7), said driving ring being connected to the driving disk and the case by means of a bearing (1-21, 3-21, 5-21). Magnetic couplings (1-12, 2-12, 3-12, 4-12, 5-12, 6-12) are situated respectively between the clock/watch movement, the driving disc (1) and the driving rings (3, 5). The radial magnetic couplings form a component part of the rotary mounted piece, consisting of an outer ring, an inner ring, magnets, a cap and a case. The outer ring (101) and the inner ring (102) consist of magnetizable material and can both rotate in relation to each other and around a single axis (x). One or several magnets (103) are fitted radially, facing inwards on the outer ring (101) and one or several magnets (104) are fitted radially, facing outwards on the inner ring (102). The magnets (103, 104) on the respective peripheral halves of the outer ring (101) and the inner ring (102) are of opposite polarity and a cap (105) consisting of non-magnetizable and magnetically permeable material is fitted between the magnets (103 and 104) of the outer and inner rings (101 and 102) and is firmly connected to a case (106).
Abstract:
The disclosed planisphere has three superimposed sheets (1, 2, 3). The lower sheets represent the two planispheres, the terrestrial (1) and the celestial (2) planispheres which are joined by a common rotation center (4) coinciding with the poles. The upper sheet (3), which is transparent as is (2), is excentric with respect to the prior ones since its rotation center is the pole of the ecliptic (5) situated in the parallel 66.5 of the celestial planisphere (2). Said sheet (3) is intended to mark out on the terrestrial planisphere (1) the areas which are illuminated (6) or which are not illuminated (7) by the sun (8). It has scientific-didactic applications since it simulates the night-day succession and the process of the seasons, while relating the positon of the stars and the height of the sun at midday with respect to places on earth. It also has industrial applications since it can be used as a watch face. Alternatives of said planisphere are obtained by suppressing any one of its three components or by providing said components as the surfaces of spherical caps.
