EMI2.1
zu gleicher Zeit aufleuchten und erkennen lassen, dass kein Seilrutschen eingetreten ist. Aus dem Vor- oder Nacheilen der Lichtsignale kann man auf den Fehler in der Angabe des Teufen- zeigers schliessen. Das Differieren der Zeichen ira den Maschinisten warnen, mit besonderer Vorsicht in die Hängebank einzufahren.
EMI2.2
der Teufenzeigerspipdel oder deren Lager hervorruft.
Es werden dann Serienkontakte vorgesehen, deren jeder vom Teufenzeiger bzw. der Kontrollvorrichtung im Schacht betätigt werden und die einen Hilfsstromkreis, durch welchen ein Motor für die Korrektur kurzgeschlossen wird,
EMI2.3
einer mehr oder weniger statken Spannung einei Feder und anderes mehr benutzt werden, die die Korrektur der Stellung des Teufenzeigers oder der Retardievrorrichtung herbeiführen. Durch die grössere Stromstärke kann beispielsweise ein Magnetanker tiefer in seine Spule eingezogen werden, der dabei entsprechend seinem grösseren Hub auch die Teufenzeigerspindel stärken vordreht oder er lädt einen Kraftspeicher, z. B. eine Feder, entsprechend stärker auf. \\eI (L {' dann die entsprechende Verstellung des Teufenzeigers bewirkt.
PATENT. ANSPRÜCHE : 1 Einrichtung zur Sicherung des Betriebes von Fördermaschinen gegen Seilrutschen.
EMI2.4
gfgehenen Anzeigen, z. B. durch Lampensignale, auf die Richtigkeit der Angaben des Teufellzeigersgeschlossenwerdenkann.

EMI2.1
light up at the same time to show that no zip line has occurred. The error in the indication of the depth indicator can be inferred from the lead or lag of the light signals. The difference in the signs warn the machinist to drive into the suspended bench with particular care.
EMI2.2
the depth pointer or its bearing causes.
Series contacts are then provided, each of which is actuated by the depth pointer or the control device in the shaft and an auxiliary circuit through which a motor is short-circuited for the correction,
EMI2.3
a more or less static tension, a spring and other more can be used to correct the position of the depth pointer or the retarder device. Due to the greater current strength, for example, a magnet armature can be drawn deeper into its coil, which also strengthens the depth indicator spindle according to its larger stroke or it loads an energy storage device, e.g. B. a spring, accordingly stronger. \\ eI (L {'then causes the corresponding adjustment of the depth pointer.
PATENT. CLAIMS: 1 device to secure the operation of hoisting machines against zip lines.
EMI2.4
Going ads, e.g. B. by lamp signals, the correctness of the indications of the devil hand can be concluded.
