摘要： The present invention relates to a protective circuit (30) for intrinsically safe electromagnetic actuators operating at the voltage of a power supply approved for underground mining, for switching electrohydraulic valves in underground mining, comprising a coil (11) connected to a first potential (2) and a second potential (3) of the power supply and associated with at least two spaced-apart short-circuit means (12) connected in parallel with the electromagnetic actuator coil (11) for short-circuiting the coil in the event of a reversal of the potential of the coil voltage. In accordance with the present invention the protective circuit comprises a semiconductor switch (T3) which is inserted between the coil (11) and the second potential (3) and, in the event of a voltage reduction or potential reversal, isolates the coil (11) from the second potential, so that the discharge from the coil (11) has no adverse effect on the energy supply system or the intrinsic safety.

摘要： The invention employs pressure and displacement sensors for the automatic monitoring and adjustment of the pre-tension of endless belts, in the form of chains or the like, which sensors determine the pressure in the cylinder space and the movement of the piston of the tensioning cylinder, and the measuring signals from which sensors are evaluated by an electronic evaluation and actuation unit. In this respect the evaluation and actuation unit calculates from the measuring signals the changes in pressure which occur over a predetermined partial stroke of the piston of the tensioning cylinder, wherein these changes in pressure reflect the state of tension of the chain belt. When the chain tension is incorrect, the evaluation and actuation unit can therefore control the tensioning cylinder so that the optimum chain tension is set automatically.

摘要： A method for controlling the main and auxiliary drives of conveyors, for example, in underground mining. The drives are controlled as a function of the loading of the conveyor in such a way that in a low load range of the conveyor the auxiliary drive produces a higher output (20.sub.I) than the main drives and as the load increases the output advantage of the auxiliary drive in relation to the main drives is reduced. This special load distribution to auxiliary and main drives has the advantage that sagging of the conveyor element, for example the chain of a scraper chain conveyor in the inaccessible and concealed lower strand, close to the main drive, can be prevented. The risk of damage to the machine frame or conveyor chain is thereby reduced.
摘要翻译：一种用于控制输送机的主要和辅助驱动器的方法，例如在地下采矿中。传动装置以传送机装载的方式被控制，使得在传送装置的低负载范围内，辅助驱动器产生比主驱动器更高的输出（20I），并且由于负载增加了输出的输出优点辅助驱动器相对于主驱动器减少。对辅助和主驱动器的这种特殊的负载分配的优点在于，可以防止输送机元件的下垂，例如靠近主驱动器的不可接近和隐藏的下部链条中的刮板链式输送机链。因此，机架或输送链的损坏风险降低。

摘要： The warning tone transmitter (10) according to the invention has a piezoelectric horn element (12) with two input connectors (29, 30) for the application of the supply voltage at a determined frequency and has a circuit arrangement (14) fed from the current supply, which generates the supply voltage. In order to be able to receive confirmation that the horn signal is actually generated by the warning tone transmitter (10) and in order to be able more easily to calibrate the warning tone transmitter (10) such that it is driven at its resonant frequency the piezoelectric horn element (12) has an additional output connector (34), which, when the horn element (12) is fed with the supply voltage, generates an answering signal taken to the circuit arrangement (14) if the piezoelement is actually oscillating. The magnitude of the answering signal is a value for the sound volume of the warning tone transmitter (10).
