Abstract: A computer program includes data defining tool paths for manufacturing a component. The component geometry is estimated based on the program. Deviation of a first type is estimated as deviation between the estimated geometry and geometry of the component as defined by a 3D model. Deviation of a second type is estimated, based on machining process characteristics indicated by sensor data captured during manufacturing of the component, as deviation between a tool path a machine is instructed via the program to provide and an actual tool path provided by the machine. Deviation of a third type is computed as deviation between geometry defined by the 3D model and measured geometry of the manufactured component. An error propagation model is updated based on the estimated and computed deviations for multiple components. The error propagation model approximates relations between deviations of the first and second type and deviations of the third type.

Abstract: A tank arrangement for a vehicle, particularly a truck, includes at least a first fuel tank and a second fuel tank which are connected by a balancing pipe, a suction pipe for feeding fuel to an engine and a return pipe for feeding fuel from the engine to at least one of the fuel tanks. The balancing pipe is provided with a first end to supply fuel to the first tank and a second end to suck fuel from the second tan, wherein a check valve is arranged upstream of the return pipe in the balancing pipe between the at least two tanks allowing a flow direction from the second tank to the first tank and blocking a flow in the reverse direction. Suction of fuel to the engine is from the first tank only. The check valve provides an automatic purging of the system.

Abstract: A liquid receptacle for a vehicle includes a first unit having a space for containing a liquid and a second unit which is attached to the first unit. The second unit includes a housing which housing accommodates a pump for conveying liquid out from the first unit and a filter for filtering the liquid to be conveyed.

Abstract: A device for mounting an oval container on a motor vehicle includes a bracket designed to be mounted vertically on the frame of a vehicle, where the bracket includes an upper arm and a lower arm. The device also includes a mounting unit including a reinforcing beam designed to be mounted on the upper arm, a beam designed to be mounted on the lower arm and at least one strap holder designed to interact with a strap for attaching the said oval container. The reinforcing beam and the beam are permanently attached to the strap holder. A method for mounting an oval container on a vehicle is also disclosed. A simple and space-saving mounting of an oval container on a vehicle can be provided.
