Abstract: The present disclosure relates to a compressor having a low-pressure region and a high-pressure region, wherein a lubricant is provided in the low-pressure region in order to lubricate the compressor. A fluid is conveyed from the low-pressure region into the high-pressure region and compressed, wherein a portion of the lubricant with the fluid from the low-pressure region reaches the high-pressure region, and wherein a lubricant separator for separating the lubricant from the fluid/lubricant mixture in the high-pressure region is provided. A lubricant return channel for transporting the separated lubricant from the high-pressure region into the low-pressure region is provided.

Abstract: The present invention relates to a piston-cylinder assembly for a radial piston compressor. The piston-cylinder assembly comprises a drive shaft with a cylindrical eccentric for guiding the movement of the piston to a top dead center position. A cylindrical piston guide ring guides the movement of the piston to a bottom dead center. Both the cylindrical eccentric and the piston guide ring are connected to the piston by means of respective concave/convex contact surfaces for the positive transmission of the forces.

Abstract: A method of training a text-generating model for grammatical error correction (GEC) includes obtaining a multilingual set of text samples where each text sample includes a monolingual textual representation of a respective sentence. The operations also include, for each text sample of the multilingual set of text samples, generating a corrupted synthetic version of the respective text sample where the corrupted synthetic version of the respective text sample includes a grammatical change to the monolingual textual representation of the respective sentence associated with the respective text sample. The operations further include training the text-generating model using a training set of sample pairs. Each sample pair in the training set of sample pairs includes one of the respective text samples of the multilingual set of text samples and the corresponding corrupted synthetic version of the one of the respective text samples of the multilingual set of text samples.

Abstract: An electric actuator for a final controlling device having a safety actuator function for positioning an actuating element, (e.g. a valve element of, for example, a process-technical plant). The electric actuator can include an electric motor configured to provide a torque for actuating the actuating element. The electric motor can include a motor shaft configured to deliver the torque, an output shaft configured to transmit the torque from the electric motor to the actuating element, and an electromagnetic and/or currentlessly uncoupling coupling (e.g. electromagnetic and/or currentlessly uncoupling clutch) configured to provide and/or interrupt a torque-transmitting connection between the motor shaft and the output shaft. The output shaft, the motor shaft and the coupling can be arranged coaxially to one another.

Abstract: The invention relates to a control valve (10) for a process plant, comprising an actuator (16) which is connected to, and spaced from, a valve body (12) of a valve unit (11) via a yoke (14), the valve body (12) having a housing flange (32) which is detachably connected to the yoke (14), with the valve body (12) having an inlet (20) and an outlet (22) adapted to allow the flow of a process fluid therethrough, which inlet (20) and outlet (22) are each arranged in a fluid connection region (18, 19), and with an actuating member adapted to be displaced by the actuator (16) for controlling the flow rate of the process fluid being arranged in the passage (24) from the inlet (20) to the outlet (22). The invention is characterized in that the housing flange (32) connected to the yoke (14) has at least one recess (44) as well as a yoke fastening region (33), with the yoke fastening region (33) being formed as a bolt hole circle (34) with radially arranged connecting holes (36).

Abstract: In a fluid-operated drive for a field device, the drive being designed to set a control valve of the field device, a fluidically operated basic drive is provided with a basic working chamber loaded fluidically and delimited by a basic drive housing part and by a basic actuating piston guided in the basic drive housing part. At least one supplementary drive is provided with a supplementary working chamber loaded fluidically and delimited by a supplementary drive housing part. The basic drive housing part and the supplementary drive housing part are displaceable in one another in accordance with a piston and chamber arrangement so that a volume of the supplementary chamber changes in the event of a relative movement of the drive housing parts.
