Abstract: A method for coating a rotating surface region of a workpiece by laser build-up welding includes fusing a powdery coating material prior to impact on the workpiece in a laser beam that is directed at the surface region, capturing a spatially resolved intensity profile of thermal radiation emitted by the workpiece, comparing at least one property of the intensity profile with at least one predefined target value, and modifying at least one parameter of a coating procedure based on a result of the comparison.

Abstract: A hydraulic machine includes a housing interior space and a group of hydrostatic working chambers which are mounted in said housing interior space so as to be rotatable about an axis of rotation and which, as the group rotates, are connectable alternately to a high pressure and to a low pressure of the hydraulic machine and exhibit leakage into the housing interior space. A heat exchanger device is accommodated in the housing interior space. The hydraulic machine may be associated with a hydraulic assembly and a hydraulic axle.

Abstract: A hydraulic unit includes an assembly with a hydrostatic positive displacement pump and an electric motor. The positive displacement pump includes a driving shaft configured to be driven by the electric motor. The hydraulic unit also includes an inert mass on which the assembly is rigidly mounted so as to minimize vibration of the assembly and reduce noise emission from the assembly.

Abstract: A method can be utilized to startup into a normal operating state a steam reformer arrangement for the production of hydrogen, methanol, or ammonia. A plurality of burners that are coupled to at least one reactor having reformer tubes may be controlled and regulated. In particular, startup may be performed out and regulated in an automated manner by the burners ensuring normal operation, in particular non-startup burners, being ignited indirectly as a function of temperature by means of burners provided specifically for startup, in particular pilot burners and startup burners, as a function of automatically evaluated flame monitoring at least at the pilot burners. This method provides time savings and savings of outlay in terms of personnel and also high operational reliability.

Abstract: A hydraulic unit includes a tank configured to be filled with a hydraulic fluid. The tank has at least one inflow connection and at least one outflow connection. A flow guide for the hydraulic fluid is formed between the inflow connection and the outflow connection. The flow guide is configured to have at least two 180° flow arcs configured to cool and calm the hydraulic fluid and to avoid dead zones.

Abstract: A reformer for production of synthesis gas may include a reformer firing space having a reformer base, reformer walls, and a reformer roof. The reformer may include a first reformer tube and a second reformer tube, with at least sections of the first reformer tube and the second reformer tube being arranged within the reformer firing space. At least one reformer burner is disposed outside the reformer firing space. A cooling duct on or beneath the reformer base is disposed between the first reformer tube and the second reformer tube. The first reformer tube and the second reformer tube can be connected to a collecting system outside the reformer firing space, with the collecting system being disposed beneath the reformer base.

Abstract: A hydraulic distributor block for fluid guidance, having at least two port surfaces which each have at least one port opening. The port openings of the port surfaces are connected by a flow duct, with the flow duct having at least one bend which is continuously curved and the port surfaces being spatially separated from one another.

Abstract: A low-temperature heat utilization assembly may be configured to decouple low-temperature heat from process gas at temperatures below 200° C. and to provide the process gas at a lowered intermediate temperature or at a still further lowered final temperature for at least one subsequent process. In the low-temperature heat utilization assembly the process gas may be fed to a first unit, by means of which the temperature may be lowered to the intermediate temperature. The process gas may in some cases be provided to a heat exchanger stage for further lowering to the final temperature. The first unit is an ORC unit for energy transformation of the heat energy into electrical energy and may be coupled to an electrical consumer unit. The ORC unit may be configured for energy feedback of electrical energy within the low-temperature heat utilization assembly or to a process upstream of the ORC unit.

Abstract: A hydraulic system has a fluid path which connects two system components fluidically to one another and which comprises a hydraulic hose. It is known to form a fluid path between two components of a hydraulic system, for example between a pump and a control block, by a single hydraulic hose which is designed in accordance with the maximum volume flow and the maximum pressure. A hydraulic hose for large volume flows and high pressures is disproportionately expensive relative to a hydraulic hose for smaller volume flows and, on account of its larger internal and external diameters, has a larger minimum bending radius than a hydraulic hose for smaller volume flows. In order to provide a cost-effective and compact structure, a hydraulic system according to the disclosure has the fluid path formed by at least two hydraulic hoses arranged fluidically parallel to one another.

Abstract: A hydraulic unit having a housing includes a tank and a pump arranged adjacent to one another in a fluid supply region, and a controller region is arranged thereabove. Since the pump is embodied in an upright design, a compact hydraulic unit with a small footprint is implemented.

Abstract: A baseplate has a top side that includes a support surface and a collecting surface. A hydraulic appliance is configured to be fastened on the support surface. The collecting surface is arranged lower in relation to the support surface so as to collect leakage oil of the appliance.
