Definitions
- the present invention relates to a time display device according to the preamble of patent claim 1.
- Such a time display device in which time intervals can be displayed by means of the amount of a medium which has flowed or flowed through an opening since the beginning of the time interval, the flow of the entire medium corresponding to a specific time interval, is known, for example, as an hourglass. Hourglasses of this type are frequently used as decorative objects or as hourglasses. The extent to which the time interval has elapsed can be read from the amount of sand that has flowed into the lower volume since the beginning of the time interval or from the (correspondingly equal) amount of sand that has flowed out of the upper volume since the beginning of the time interval ,
- the present invention addresses the problem of improving the accuracy of the display of such a time display device.
- a correction can advantageously be made by the size of the opening being adjustable.
- the flow rate can then be adjusted to give an accurate time display.
- the time display device can be "set” by briefly changing the size of the opening.
- the solution according to claim 1 shows that the improvement in display accuracy can be achieved by an automated function. Manual intervention for re-adjustment is not necessary.
- the medium can be fluorescent or luminescent.
- a reading in dark rooms can then also advantageously take place.
- the time display device can be coupled to a clock, the opening being changed such that the display of the expiry of the time interval by the flow rate is synchronized with the time display of the clock from the beginning of a time interval.
- control element is controlled by the clock.
- the clock can be controlled via an external time signal.
- Such clocks are known for example as radio clocks. These can receive the DCF-77 signal, on the basis of which these clocks can be synchronized with the high-precision clock of the Physikalisch-Technische Bundesweg in Braunschweig.
- the time display device consists of two volumes connected to one another by the opening, one volume of which is attached above the other, the medium being in the upper volume at the beginning of a time interval. Furthermore, the time display device should be rotatable so that the position of the two volumes is interchangeable, the rotation taking place at defined times. For a certain period of time before one of the defined points in time, the opening is expanded at least if there are still remnants of the medium in the upper volume.
- the time display device can then be designed, for example, as an hourglass, in which the sand runs through every hour.
- the hour meter is then turned every hour on the hour.
- the specific time period can be dimensioned such that it is approximately 10 seconds.
- the opening is then set to "maximum" for a period of approximately 10 seconds before every full hour, so that any remaining amount of sand can pass through during this period.
- the opening is then closed completely or returned to its normal position.
- the opening can be, for example, an electronically controlled ring opening.
- the opening is therefore advantageously closed again or set to its normal position before the rotation, in order to avoid that at the beginning of the new time interval a quantity of sand which cannot be controlled or can only be controlled with difficulty, which would mean an incorrect display, is passed through.
- the rotation can be realized by reversing the polarity of electromagnets.
- the rotation can also be implemented by means of a mechanical adjusting element.
- the opening can be changed as a function of a measurement of the flow rate of the medium and / or as a function of a measurement of the medium that has flowed through and / or remained at certain times in a time interval.
- the display can advantageously be adapted, which becomes effective during the entire time interval.
- it is therefore not only an adjustment at the end of the time interval, the time being displayed with a corresponding inaccuracy during the time interval.
- the overall display accuracy can then be improved over the entire period.
- the single figure shows a time display device 1, which is designed as an hourglass.
- This hourglass 1 has an upper volume 2 and a lower volume 3.
- these volumes are each closed with plates 4 and 5, which are magnetic. Due to a corresponding polarity of the electromagnets 6 and 7, which can be supplied with current at the contacts 8, 9 and 10, 11, respectively Repulsion can be realized so that the hourglass 1 is then rotated. The position of the upper volume 2 and the lower volume 3 are then exchanged.
- a rotation can also be realized by means of a mechanically acting adjusting element. This can be achieved, for example, by means of a spring tension.
- a mechanically acting control element can also be a stepper motor which is controlled accordingly.
- a clock 12 which can have an analog time display 13 and / or a digital display 14. Furthermore, this clock can have an antenna 15 for receiving a DCF-77 time signal, so that this clock can be synchronized as a radio clock with the time signal.
- the clock 12 can therefore be analog or digital or can also include both display options. Hours, minutes and seconds can be displayed as well as a day, month and / or year. The number of hours can also be displayed, for example, through the sand run.
- a signal can be emitted from the clock 12 to a control device 17 via a signal line 16.
- This control unit has several outputs.
- An output 18 goes to the contacts 8 and 9 of the electromagnet 6 in order to apply a current to it, so that the electromagnet 6 is poled in a certain direction.
- Another output 19 goes to the contacts 10 and 11 of the electromagnet 7 in order to apply a current to it, so that the electromagnet 7 is poled in a certain direction.
- an output 20 can be seen, with which, for example, an electronic ring opening 21 of the opening of the hourglass 1 can be controlled.
- the hourglass 1 is designed with respect to the opening that connects the volume 2 with the volume 3 so that the sand or another flowable medium flows from the upper volume 2 into the lower volume 3 in one hour.
- the sand can, for example, be marked in such a way that it has a fluorescent or luminescent effect.
- the clock 12 is used to synchronize the hourglass 1 in order to compensate for possible inaccuracies.
- the clock 12 can be designed as a radio clock. In the event of a power failure or other malfunction of the hourglass, synchronization can then be carried out again by setting the exact time after switching on the device again.
- the opening can first be opened completely until the next rotation of the hourglass is initiated in order to bring about a synchronization of the hourglass. This can ensure, for example, that the sand has completely flowed into the lower volume 3 before the rotation.
- a first signal is sent from the clock 12 to the control unit 17 via the signal line 16.
- the control unit 17 then emits a signal to the electronically controllable ring opening 21 via its output 20, which causes the ring opening 21 to open completely.
- the control device 17 now causes the ring opening 12 to be closed via its outlet 20.
- This ring opening 21 can be completely closed or reset to its normal position.
- the electromagnets 6 and 7 are then actuated via the outputs 18 and 19, which causes the hourglass 1 to rotate. If the magnets 4 and 5 and the electromagnets 6 and 7 are appropriately polarized, they are repelled to initiate the rotation and attract when the rotation is 180 degrees.
- the ring opening 21 is reset to the normal position after the rotation.
- a measurement of the sand flow or a volume measurement of the sand which has flowed off or a weight determination of the sand in the lower vessel can also be carried out in order to make a corresponding adjustment of the ring opening 21.
- this is more complex in terms of sensors, it allows the ring opening 21 to be set in such a way that the display accuracy is improved during the entire time interval.
