Abstract: A control valve incorporates a valve housing with a main body having a valve inlet and valve outlet, a valve seat in the flow duct between the valve inlet and valve outlet, a valve cage in the flow duct between the valve inlet and valve outlet, and a valve member which is movable in the axial direction (a) relative to the valve seat and valve cage and connectable to an actuator rod of a drive via a drive rod. The valve housing has an extension body extending the main body in the axial direction (a) and a valve cover which closes the extension body and through which the actuator rod can sealably pass. The control valve further includes a circulation barrier in the valve housing which prevents circulation of a process medium in the extension body. The circulation barrier and the valve cage are in contact with each other via contact pressure surfaces opposite one another in the axial direction (a). The circulation barrier and valve cage components are jointly fixed in the valve housing via a fastening means.

Abstract: A computer-implemented method for generating control parameters for auto-docking of a marine vessel, and to a control unit for executing the method, to a marine vessel including the control unit, and to a corresponding computer program product.

Abstract: An agricultural harvesting machine and a method for operating an agricultural harvesting machine. The agricultural harvesting machine includes an attachment configured to receive a crop containing grain components, at least one work assembly for processing the received crop, a transfer device, a near-infrared (NIR), and an evaluation device. The crop is received by the attachment and traverses the harvesting machine, thereby defining a crop stream. The NIR sensor is positioned along the crop stream downstream from the at least one work assembly and generates one or more signals indicative of at least one aspect of the grain components in the crop stream. Further, the evaluation device receives and analyzes the signals from the NIR sensor in order to determine a degree to which the grain components contained in the crop stream are cracked.

Abstract: An agricultural harvesting system has an agricultural harvesting machine with at least one agricultural working unit that performs agricultural work, and an adjusting unit for adjusting the parameters of the particular working unit, a conveyor channel for a crop stream generated in a harvesting process by harvesting a field of crop, and an NIR sensor unit containing an NIR sensor which is configured for detecting constituents and/or properties of the crop stream. The crop stream in the conveyor channel can be guided past the NIR sensor. An on-line data processing unit controls the particular working unit, and generates control data on the basis of crop stream data which have been generated by the NIR sensor unit and correspond to the constituents and/or properties detected by the NIR sensor, and the adjusting unit carries out a parameter adjustment of the particular working unit on the basis of the control data.

Abstract: The present invention relates to an exchangeable insert seat member for a metal cutting tool having a tool body and a cutting insert. The exchangeable insert seat member is arranged to be placed between the tool body and the cutting insert, wherein the exchangeable insert seat member contacts the tool body. The cutting insert at contact areas is arranged such that there is no direct contact between the tool body and the cutting insert and wherein the exchangeable insert seat member is produced by powder injection molding. The present invention also relates to a metal cutting tool having the exchangeable insert seat member.

Abstract: A method and plant for obtaining acetic acid and methanol from the hydrolysis of methyl acetate by reactive distillation is disclosed. The reactive distillation column is configured as a divided wall reactive distillation column (1). A feed containing water and methyl acetate are brought into contact with a catalyst in a reactive space (19) to perform the hydrolysis of water and methyl acetate to methanol and acetic acid. The reactive space comprises at least a first rectification zone (32), a first stripping zone (34) and a first reaction zone (33). A catalyst is provided in the first reaction zone (33). The column further comprises a product space (29) with at least a second rectification zone (42) and a second stripping zone (44). The second stripping zone (44) shares at least a portion of the column sump (38) with the first stripping zone (34).

The second stripping zone shares at least a portion of the column sump with the first stripping zone. A first head product is discharged from a reactive space head portion and a bottom product is discharged from the column sump and a second head product is discharged from a product space head portion and an intermediate product is discharged from the product space.

Abstract: Carboxylic acid ester is produced by esterification of carboxylic acid and an alcohol in a catalytic reaction zone of a first column at a pressure not greater than ambient pressure. The resultant sump product is distilled in a reaction zone of a second column at a pressure greater than 1.5 bar to obtain a second liquid sump product containing carboxylic acid ester with an carboxylic acid content of less than 100 ppm by weight at a lower end of the column. Neutralization of the second liquid sump product with a base is not required.
