Abstract: An apparatus of a setting welding device for an auxiliary joining part with a head and a shaft, includes a linear drive fastenable at the setting device and including an element nest at a movable end, in which an auxiliary joining part is releasably receivable from a transfer unit. The element nest is movable by the linear drive in a first direction. The element nest is supported in a floating manner, and is positionable via a mechanical stop alignment in abutment with an electrode punch in the joining direction below the electrode punch. And/or the element nest is connected with the linear drive via a mechanical direction-changing coupling component so that the element nest is movable by the linear drive in a second direction so that the auxiliary joining part is positionable at the joining location, wherein the second direction is not parallel to the first direction.

Abstract: An arrangement for power distribution on a vessel, having: a first DC bus operating at a first medium voltage; at least one second DC bus operating at a second medium voltage and having no direct connection with the first DC bus; a first AC bus operating at a low voltage; a first inverter coupled between the first DC bus and the first AC bus for allowing power flow from the first DC bus to the first AC bus in a first operation mode; a second AC bus operating at the low voltage; a second inverter coupled between the second DC bus and the second AC bus for allowing power flow from the second DC bus to the second AC bus in the first operation mode; a low voltage connection system for selectively connecting or disconnecting the first AC bus and the second AC bus.

Abstract: At least one embodiment of the invention generally relates to a drive system for a facility having an alternating-current isolated network, in particular for a ship or an offshore platform, including a three-phase drive machine, which can be operated both as a motor and as a generator, and including a converter having a direct-current intermediate circuit having an intermediate circuit voltage. At least one embodiment of the invention aims to provide a way of avoiding undesired and/or impermissible voltage and/or frequency increases in the alternating-current isolated network.
