TL;DR: In this paper, the authors proposed a method for controlling a connection of a power unit or a charging unit to an accumulator or a battery with a supply network, where four valve paths (VP1-VP4) are provided in each connection unit.
Abstract: The circuit has connection units (S1-S3) whose output sides are connected with each other in series or parallel to form an intermediate circuit. The connection units are connected with ports (L1-L3, N) of a supply network. Four valve paths (VP1-VP4) are provided in each connection unit. The valve paths are connected with the ports of the supply network, and comprise rectifying elements (D1-D4, T1-T4). The valve paths are switched parallel to each other or form a rectifier bridge e.g. full steered rectifier bridge or half steered rectifier bridge. An independent claim is also included for a method for controlling a connection of a power unit or a charging unit to an accumulator or a battery with a supply network.

TL;DR: In this paper, a region with rear undercuts is provided during foaming of a pre-fabricated lightweight core and a surface area of the lightweight core is aligned at definable distance from surfaces of the foaming tool by protruded fixing pins.
Abstract: The method involves providing a region with rear undercuts foamed during foaming process in a pre-fabricated lightweight core (2) and in operation of lightweight core such that the lightweight core is inserted in a closed foaming tool. A surface area of the lightweight core is aligned at definable distance from surfaces of the foaming tool by protruded fixing pins (3). The lightweight core is foamed with a compact load-bearing polyurethane system (1) for enabling a cohesive connection with a material of the protruded fixing pins. An independent claim is also included for a polyurethane-mold part comprising a pre-fabricated lightweight core.

TL;DR: In this paper, a car body component is constructed with an outer shell made of thermoplastic resin, and a supporting layer made of foamed plastic and connected with the outer shell, where the foam body is dimensioned such that a space between the inner shell and adjacent components is filled.
Abstract: The component (7) has an outer shell (4) made of thermoplastic resin, and a supporting layer made of foamed plastic and connected with the outer shell. The supporting layer consists of a foam body (5) that is foamed to the outer shell, where the foam body is made of expanded polystyrene (EPS). The foam body is dimensioned such that a space between the outer shell and adjacent components is filled. Functional components, attachment members (11) and amplification components are integrated into the foam body. Crash absorbers are integrated at the foam body. An independent claim is also included for a method for manufacturing a car body component.

TL;DR: In this article, the authors propose a tool for automatically docking and undocking an industrial robot, and a gripper for gripping, holding, or positioning a profile body (8).
Abstract: The tool has a docking port for automatically docking and undocking an industrial robot, and a gripper for optionally gripping, holding or positioning a profile body (8). A pressing device slightly presses the profile body to a component. Guide rollers (5) engage with a rolling surface at sides of the profile body projecting from the component such that the guide rollers are automatically adaptable to different profile body forms. The guide rollers are pivotable about an axis parallel to a longitudinal axis of the profile body.

TL;DR: In this paper, a material-deforming tool with the components is cooled with a coolant, i.e. pure water, after removal and before insertion of the components.
Abstract: The method involves deformation and cooling of armor components (B) in a material-deforming tool (10) in a heated state. The material-deforming tool with the components is cooled with a coolant i.e. pure water, after removal and before insertion of the components. The coolant is applied as atomized spray (N) on idle rear outer surfaces (8) of the tool. The atomized spray is produced by micro atomization of the coolant by nozzles (13) i.e. micro nozzles. The micro nozzles are distributedly arranged over a surface opposite to the outer surface of the tool. An independent claim is also included for a deformation press.

TL;DR: In this article, the core material is formed as honeycomb structure, foam structure and cup-shaped structure, and a fixing pin projects between the foils and into the recess, and fixes the structure tangential to the joining surface in a direction relative to the latter structure.
Abstract: The compound has a lightweight-sandwich structure (1) comprising two cover foils (3, 4) held at a distance to each other by a core material (5). Another lightweight-sandwich structure has a joining surface forming angle joint with a front side of the former structure. The joining surface has a recess between the foils in angle joint, and is joined with the structure along the angle joint by gluing. A fixing pin (10) projects between the foils and into the recess, and fixes the structure tangential to the joining surface in a direction relative to the latter structure. The core material is formed as honeycomb structure, foam structure and cup-shaped structure.An independent claim is also included for a method for producing a joining compound.

TL;DR: In this paper, the gripper counter jaws form gripping points for an end of a cable (A1) with gripper jaws in the release condition, and the gripping points are spaced from each other in a longitudinal direction of the cable.
Abstract: The tool (10) has a carrier (20) attached to an actuator (3), and gripper counter jaws movable back and forth relative to gripper jaws between a gripping condition and a release condition. The gripper counter jaws form gripping points for an end of a cable (A1) with the gripper jaws in the release condition, respectively. The gripping points are spaced from each other in a longitudinal direction of the cable. The gripper jaws or the gripper counter jaws are movable relative to each other so that differences in the thickness of the cable is automatically compensated. An independent claim is also included for a device for manufacturing a cable loop.

TL;DR: In this paper, gear members are coupled with a holder and movable relative to each other so that relative movement of gear members causes movement of the holder, and a spring element (20) is supported with spring ends (21, 22) at the gear members to set a spring force against the movement of a holder along opening direction.
Abstract: The drive has gear members (6, 7) coupled with a holder and movable relative to each other so that relative movement of the gear members causes movement of the holder. A spring element (20) i.e. spiral spring, is supported with spring ends (21, 22) at the gear members to set a spring force against the movement of the holder along opening direction. The spring element is deflected by the relative movement of the gear members around a spring axis (A) that faces transverse to a direction (minus Z) of the movement of the holder.
