Description

Elektrisches Zählwerk, insbesondere Uhr.
EMI1.1
<Desc/Clms Page number 2>
EMI2.1
versetzt und überträgt seine Bewegung beispielsweise mittels eines auf ihm befestigten Hakens o auf das Steigrad p des Räderwerkes. Damit die zur Erzielung eines vollkommen gleichförmigen Ganges erforderliche Schwingungszahl bei Temperaturschwankungen keine Beeinflussung erfährt, sind in den Schwingungserzeuger an geeigneter Stelle, z. B. in dessen Anodenkreis, Kompensationsorgane mit einem negativen Temperaturkoeffizienten eingeschaltet.
Gemäss den Fig. 3 und 4 ist der Anker als eine am Umfange mit Zähnen q versehene Scheibe r ausgebildet, welche unter dem Einflusse des elektromagnetischen Feldes absatzweise weitergesehaltet wird. In einer Entfernung etwa des eineinhalbfaehen der Zahnteilung von einem der Polsehuhe h ist ein radialgestellter, permanenter Magnet s vorgesehen, dessen einer Schenkel in die Nähe des Umfanges
EMI2.2
ist, um die Scheibe r in den magnetischen Kreis des Magnetes s einzuschliessen. Da der Höchstwert des durch die Polschuhe/t flutenden elektromagnetischen Feldes grösser als die Stärke des Magnetes s ist, wird beim Anwachsen des Feldes der den Polschuhen h zunächst liegende Zahn q unter diese gezogen, worauf beim Abflauen des Feldes der nunmehr überwiegende Magnet s auf den derart in seine Nähe gebrachten Zahn q einwirkt.
Die Schaltung der Scheibe r erfolgt vollkommen geräuschlos.
An Stelle eines Röhrengenerators könnte auch jedweder zu diesem Zwecke geeignete, masseund trägheitslos arbeitende Generator herangezogen werden.
Ferner könnte auch die von einem zentralen Sender ausgestrahlten, hochfrequenten Schwingungen zum gleichzeitigen Antriebe bzw. zur Steuerung einer Reihe von Zählwerken, insbesondere Uhren, dadurch ausgenutzt werden, dass diese als die hochfrequenten Schwingungen in niederfrequente umwandelnde Empfangsapparate ausgebildet sind, welche alsdann in sinngemässer Weise die niederfrequenten Schwingungen ausnutzen.
PATENT-ANSPRÜCHE :
1. Elektrisches Zählwerk, insbesondere Uhr, deren Betätigung bzw. Steuerung unmittelbar auf rein elektrischem Wege, z. B. durch von einem als Sehwingungserzeuger wirkenden Röhrengenerator erzeugte Stromstösse, erfolgt, dadurch gekennzeichnet, dass die Stromstoss besonders niederfrequente, isochrone Pulsationen in der Frequenz von 1 bis 10 Schwingungen in der Sekunde sind.

EMI2.1
moves and transmits its movement, for example by means of a hook o attached to it, to the steering wheel p of the gear train. So that the number of vibrations required to achieve a completely uniform gear is not influenced by temperature fluctuations, the vibration generator is located at a suitable point, e.g. B. switched on in the anode circuit, compensation organs with a negative temperature coefficient.
According to FIGS. 3 and 4, the armature is designed as a disc r provided with teeth q on its circumference, which is held in intermittent position under the influence of the electromagnetic field. At a distance of approximately one and a half times the tooth pitch from one of the pole shoes h, a radially positioned, permanent magnet s is provided, one leg of which is in the vicinity of the circumference
EMI2.2
is to enclose the disk r in the magnetic circuit of the magnet s. Since the maximum value of the electromagnetic field flowing through the pole pieces / t is greater than the strength of the magnet s, as the field increases, the tooth q that lies next to the pole pieces h is pulled under them, whereupon the now predominant magnet s hits the when the field decreases tooth q thus brought close to it acts.
The switching of the disk r is completely noiseless.
Instead of a tube generator, any generator that is suitable for this purpose and that works without mass or inertia could be used.
Furthermore, the high-frequency vibrations emitted by a central transmitter could also be used to simultaneously drive or control a number of counters, in particular clocks, in that they are designed as the high-frequency vibrations in low-frequency converting receiving devices, which then analogously to the take advantage of low-frequency vibrations.
PATENT CLAIMS:
1. Electric counter, in particular clock, whose actuation or control directly by purely electrical means, z. B. by current surges generated by a tube generator acting as a visual vibration generator, characterized in that the current surges are particularly low-frequency, isochronous pulsations at a frequency of 1 to 10 oscillations per second.
