Abstract: Disclosed herein are system, method, and device embodiments for implementing semantic discovery. An embodiment operates by retrieving a plurality of entities from a database instance. A semantic graph representation of the plurality of entities is generated within a graphical user interface. Context information is received from a user. A focus node is determined from the plurality of nodes using the context information. A semantic context of the focus node is determined, wherein the semantic context includes the focus node, a subset of the plurality of nodes, and subset of the plurality of edges. Responsive to the receiving, a visual indication of the semantic context is displayed within the graphical user interface.

Abstract: The electrical system comprises a cover (206) for closing the compartment (204) defined in a housing (202). The electrical system further comprises a removable element (214) configured to be mounted proximate to the housing (202), and a mobile hook (208) attached to one amongst the cover (206) and the housing (202), and configured to take an engaged position with the other amongst the cover (206) and the housing (202) and a disengaged position from the other from the cover (206) and the housing (202), wherein the removable element (214), when mounted proximate to the housing (202), is configured to cooperate with the mobile hook (208) to prevent the cover (206) from being separated from the housing (202), thereby preventing an opening of the compartment (204).

Abstract: A tool and die set and related method of use of the tool and die set in a press for the compaction of a powder metal into a preform involves an uneven amount of positional deflection of at least two lower or upper tool members. This asymmetrical elastic response under load may help to eliminate cracking of the part after the compressive load is removed.

Abstract: A camshaft adjusting device for a motor vehicle has a stator and a rotor adjustable relative to the stator in a circumferential direction by a pressure medium. A restoring spring is arranged in a spring chamber and is configured to rotate the stator and the rotor relative to one another into an initial position when an engine of the motor vehicle is turned off. The restoring spring has a rotor end positive-lockingly connected to the rotor and a stator end positive-lockingly connected to the stator. One of the rotor end and the stator end is provided with a convexly curved embossment that cooperates with a convexly curved outer side of a positive-locking counter element on the rotor or stator, respectively. The embossment is provided at a radially outer end of the restoring spring. The restoring spring is a flat spiral spring.

Abstract: The invention concerns a load torque lock for automatically locking load-side torques in the case of a decrease or cessation of a drive-side torque having a housing (11) fixed to a frame, a locking ring (17) permanently connected to it and a locking body (17) cooperating with it and revolving on the drive side, with locking devices which, on the one hand, clamp on the locking ring (17) with the occurrence of a load torque by swiveling the locking body (17) by means of locking elements (27, 28) of the output shaft (15) and, on the other hand, release from the locking ring (17) by swiveling the locking body (17) back by means of driving elements (23, 24) of the drive shaft (14). To avoid undesired friction or defective jamming of the locking devices on the locking ring (18) by the centrifugal forces of the locking body (17) it is embodied in such a way that its mass center of gravity (M) lies in the area of the rotational axis of the drive shaft and the output shaft that are aligned with one another.

Abstract: A camshaft adjuster for internal combustion engines of motor vehicles has a stator having a casing and stays connected to the casing and projecting radially inwardly. A rotor rotatable relative to the stator is fastened on the camshaft. The rotor has a rotor base member and vanes connected thereto. The vanes project into spaces between the stator stays. The stays each have an end face that rest sealingly against the rotor base member. The vanes of the rotor each have an end face resting sealingly against an inner peripheral wall of the stator. At least one of the vanes of the rotor has a damping element and the stator has at least one counter damping element. Upon rotation of the rotor into its end position, the damping element interacts with the counter damping element and slows the movement of the rotor into the end position.
