Abstract

Abstract An autonomous radio timepiece having a time equalizing processor to control and potentially correct the instantaneous time indication on the basis of the prevailing time information received by radio transmission, is equipped with an improved device for temporarily interrupting operation of the time indication. Such a device is provided for the purpose of interrupting the display function of the radio timepiece without deactivating the other auxiliary and operating functions of the radio timepiece, so that following termination of the interruption, normal operation continues without any interference. The display may be interrupted indirectly or directly. In the first case the reset inlet of the time equalizing processor is actuated to trigger the synchronizing process, which otherwise takes place upon the actuation of the radio timepiece. In the other case, the actuation of the display indexing device is electrically blocked in order to temporarily retain a predefined, just attained position of the gear (for example, to provide sufficient time to mount the hands of the display device during assembly of the radio timepiece).

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 82 words
An autonomous radio timepiece comprising: a receiver-demodulator; a time equalizing processor for providing time equalization in the radio timepiece by correcting a prevailing time indication when such an indication deviates from time information received by radio transmission; a time keeping circuit; an indexing device for adjusting the time indication; and an interrupting connection for initiating the time equalization following an interruption of the time indication and for electrically blocking actuation of the time indication without otherwise interrupting operation of the radio timepiece.
Claim 2
Dependent Claim 82 words
An autonomous radio timepiece comprising: a receiver-demodulator; a time equalizing processor for providing time equalization in the radio timepiece by correcting a prevailing time indication when such an indication deviates from time information received by radio transmission; a time keeping circuit; an indexing device for adjusting the time indication; and an interrupting connection for initiating the time equalization following an interruption of the time indication and for electrically blocking actuation of the time indication without otherwise interrupting operation of the radio timepiece.
Claim 3
Dependent Claim 25 words
A radio timepiece according to claim 1, wherein the interrupting connection includes an interrupting contact which is carried on a reset inlet of the processor.
Claim 4
Dependent Claim 26 words
A radio timepiece according to claim 1, wherein said interrupting connection includes an interrupting contact which is carried on an inhibit inlet of the indexing device.
Claim 5
Dependent Claim 22 words
A radio timepiece according to claim 3, wherein the interrupting contact places one pole of a power supply on the inhibit inlet.
Claim 6
Dependent Claim 37 words
A radio timepiece according to claim 4, wherein the radio timepiece is located within a works case, and said interrupting contact is located externally on the works case so as to be accessible to a contact rail.
Claim 7
Dependent Claim 30 words
A radio timepiece according to claim 5, wherein the interrupting contact is mounted as a counter contact for an assembly contact rail in an accessible manner on the works case.
Claim 8
Dependent Claim 22 words
A radio timepiece according to claim 3, wherein the interrupting contact is conductively connected through a memory circuit to the indexing device.
Claim 9
Dependent Claim 33 words
A radio timepiece according to claim 7, wherein the memory circuit is prepared during startup of the radio timepiece by means of a power supply and deactivated by means of the interrupting contact.
Claim 10
Dependent Claim 25 words
A radio timepiece according to claim 3, wherein the interrupting connection includes another interrupting contact which is carried on a reset inlet of the processor.
