Abstract: A control device for electrohydrualic support controllers, with an electronic individual controller including a plug board that contains first connecting pieces, a terminal block that is mounted to a corresponding support frame and includes recesses for holding second connecting pieces, plug-in connectors for connecting cables for communicating with adjacent controllers, and at least one external power supply. A connecting plug, to which the lamp can be connected with its connecting cable, is attached to the terminal block.

Abstract: The present invention is an individual controller for shield support frames in underground mining, having a shallow box-shaped housing for holding microelectronics comprising a top wall, a bottom wall, two side walls, a front wall and a back wall, with receptacles for connecting cable plugs from sensors and actuators and with at least one socket for connecting a plug of a cable for communicating with an adjacent individual controller.

Abstract: A controller is disclosed for control operations in underground mining, especially for controllers to control support shields. The controller utilizes a central unit with a microprocessor and assigned, programmable memory devices for the storage and processing of software as well as a connector unit with connectors or circuits for communication between the controller and other controllers and/or actuators, sensors or the like, that are to be controlled with the controller. Both the central unit and the connector unit utilize a modular design. A collection of modules with different performances and/or functionalities are provided for both the central unit and the connector unit to form the hardware of a controller. The modules can be combined with one another and coupled together according to a modular concept.

Abstract: The invention concerns a mining lamp 1 with a signal display. The mining lamp 1 is characterised in that it includes a large number of light diodes 3 and a control device 9, by means of which the light diodes 3 can be controlled individually or in groups, in order to display symbols, flashing signals, letters, text, patterns and/or similar.

Abstract: The pressure cell device according to the invention serves for measuring hydraulic pressures in hydraulic mining devices in an inherently secure service region. It is provided with a connection element which can be connected to a pressure reception connection and with a sensor housing, on the inside of which is arranged a hydroelectric pressure transducer which is pressurised by the hydraulic pressure present at the pressure reception connection and converts this into an electrical signal. So as to ensure high measurement accuracy over a long operating period, without it being necessary to have exchanges of the pressure transducer or its new calibration, it is provided according to the invention that the pressure transducer comprises a ceramic pressure measuring cell.

Abstract: A control device (10) for electro-hydraulic support frames with a casing (11) accommodating a circuit, several plug-in connectors (20) accessible from outside the casing (11) for the connection of control leads, and with actuating control elements (13) connected to the circuit. The control elements (14, 15, 16, 17, 18) are grouped together in several exchangeable modules (27), accommodated in the casing (11), which are connected to the circuit and to each other by plug-in connecting elements (30) when installed in the casing (11). The modules (27) are exchangeable independently of each other. The operating keys of a keyboard (16) and/or an indicator unit (18) can be combined in one operating module (28), which can be removed from the casing (11). The actual control of the control device in the casing (11) and operation of the support frame is permitted to continue during the exchange of the operating module (28).
