Abstract: A cutting roller bearing part, formed as a component of a cutting roller holder for a cutting wheel of a tunnel boring machine, includes a load measuring unit disposed in a receiving space assembly including though lines which is hermetically sealed against an external atmosphere by external closures and a sealing element to provide accuracy and long-term stability for load measurements.

Abstract: A device for detecting a content of critical gas in a mining chamber of a tunnel boring machine includes a separation module by which a fluid fed in via an extraction line connection is cleaned of solid and liquid components. A gas line arrangement arranged downstream of the separation module in the flow direction of the fluid carries the fluid, including substantially only gaseous components, through a pressure reducer and through a flow control valve of a metering module by which the gas to be analyzed can be delivered in a controlled manner assisted by a double diaphragm pump and a pressure stabilizer to a gas analysis unit even at high pressures in the cavity.

Abstract: A control device for call control and a system comprising such control device is disclosed. The control device is configured to be electrically connected to an external device, such as a computer, through a first electrical cable, where the control device is configured to be electrically connected to a headset through a second electrical cable, where the control device comprises adjustment means. The control device comprises means for being detachably attached to a fixation member that is configured to be permanently attached to a firm and solid member.

Abstract: An electronic unit, in particular a control device for a motor vehicle, has a printed circuit board, populated with electronic components, and a housing enclosing the printed circuit board. The printed circuit board has at least one first section, arranged at a distance from the housing and equipped with electronic components on both sides thereof, and at least one second section which is connected to the housing by way of a heat-conducting adhesive layer.
