  • Patent number: 9830291
    Abstract: A connecting device (27) has a first connection input (28), a second connection input (29), and a connection output (30). The two connection inputs (28, 29) are configured for connection to a bus coupling device (20, 21). The connection output is configured for connection to a subscriber (13). The first connection input (28) is connected without switches to the connection output (30) via a first connecting branch (31). The second connection input (29) is connected without switches to the connection output (30) via a second connecting branch (32). The connecting device (27) includes a diagnostic unit (39), which generates a diagnostic signal (D) depending on the first input voltage (U1) and/or the first input current (I1) at the first connection input (28) and/or on the second input voltage (U2) and/or the second input current (I2) at the second connection input (29).

  • Patent number: 9742269
    Abstract: A voltage control circuit for electrically coupling a field device coupler to a bus line. An input voltage (UE) provided at the voltage control circuit by the bus line is converted into an output voltage (UA) that can be regulated and limited. If a current limitation is additionally provided, the “inherent safety” ignition protection type can be achieved. The voltage control circuit has a chopper-type regulator without galvanic isolation. A parallel path is formed parallel to the chopper-type regulator by a series connection of two buffer capacitors. Communication signals of higher frequency can be transmitted past the chopper-type regulator via the parallel path. The parallel path and a reference terminal of the chopper-type regulator are additionally connected via an impedance circuit to a reference potential at a second input terminal of the voltage control circuit.

  • Patent number: 6510585
    Abstract: A turbo tool includes a housing forming a hollow section. The housing includes at least one air inlet and a nozzle opening spaced from the air inlet, a brushroll rotatably mounted in the housing and within the nozzle opening and a turbine. The turbine is drivingly connected to the brushroll for rotating the brushroll. The turbine is driven by a first airflow through the air inlet. A rotational axis of the brushroll is parallel to a longitudinal axis of the turbine and parallel to a longitudinal axis of the housing. A first conduit is located in the housing and connected to the nozzle opening. A second airflow occurs through the first conduit. A second conduit is fluidly connected to the first conduit and to a third conduit. The first and second airflows merge into the second conduit. A swivel attachment is connected to the third conduit and swivels the housing between two positions approximately 180 degrees apart and is locked into one of the two positions.
