This invention relates to a synthetic resin tank which can prevent being damaged when it expands or contracts by the change of ambient temperature, though it can be easily fixed on the vehicle with fasteners such as a bolts, without the need of belts for securing it to the vehicle. The synthetic resin tank comprises a body (4) which defines a storage space for fluid and fixing means (6) which are attached to the body (4). At least one recess (42) is formed on a surface of the body (4). The fixing means (6) includes at least one elastically deformable plate portion (46) which covers the recess (42) partially and which has a through hole (50).

The present disclosure relates to a cutting drum (24A; 24B; 24C) for a mobile mining machine (10). The cutting drum (24A; 24B; 24C) comprises an outer circumferential face (34) extending between first and second end faces (36, 38). The cutting drum (24A; 24B; 24C) further comprises at least one first support arm (54) including a cutting tool (56) and being pivotably mounted to the outer circumferential face (34). The first support arm (54) is pivotable into a working position, in which the cutting tool (56) of the first support arm (54) is positioned beyond the first end face (36) in a direction of a central longitudinal axis (D) and away from the second end face (38). Thus, for example, material remaining in the interspaces between neighboring cutting drums arranged side by side can be cut by the cutting tool (56) of the first support arm (54).

The present disclosure relates to a pre-combustion chamber assembly (60) for internal combustion engines operating at least partly on gaseous fuel. In case of an additional gaseous fuel supply within the pre-combustion chamber assembly (60), an ignition device is required to be displaced out of center due to a lack of installation place in a central region. Thus, the disclosed pre-combustion chamber assembly (60) may comprise a pre-combustion chamber main portion (92) having a main portion central axis (93) that may extend in parallel to pre-combustion chamber assembly longitudinal central axis (63) with a predetermined offset (91). The pre-combustion chamber assembly (60) may further comprise an ignition device configured to initiate a combustion event at an ignition point (99) within the main portion (92). The ignition point (99) may lie substantially on the main portion central axis (93).

The MOTOR project focuses on ICT-enabled design optimization technologies for fluid energy machines (FEMs) that transfer mechanical energy to and from the fluid, in particular for aircraft engines, ship propellers, water turbines, and screw machines. The performance of these machines essentially depends on the shape of their geometry, which is described by functional free-form surfaces. Even small modifications have significant impact on the performance; hence the design process requires a very accurate representation of the geometry. Our vision is to link all computational tools involved in the chain of design, simulation and optimization to the same representation of the geometry, thereby reducing the number of approximate conversion steps between different representations. The improved accuracy and reliability of numerical simulations enables the design of more efficient FEMs by effective design optimization methods. MOTOR also exploits the synergies between the design optimization technologies for the different types of FEMs that have so far been developed independently. MOTOR adopts a modular approach for developing novel methodologies and computational tools and integrating them into real process chains, contributing a volumetric mesh generator with exact interface matching for multi-domain geometries enabling high-order multi-physics simulations with enhanced accuracy, an isogeometric analysis simulation toolbox for CFD, CSM, and FSI problems and advanced interactive visualization toolkit for high-order solutions, and automatic shape optimization based on a multi-level approach in the parameterization enabling different levels of shape variety to combine design space exploration with local searches. The effectiveness of our approach in terms of reduced time to production and increased efficiency of the optimally designed product will be validated by developing four proof-of-concept demonstrators with the modernized process chains.
