Abstract:
The invention relates to an installation switchgear (1) with at least one pole current path (2), said switchgear comprising two fixed contact pieces (5, 6) and two mobile contact pieces (8, 9) arranged on a mobile contact bridge (7), forming a pole switch with two contacts and a double break. The contact bridge (7) is acted upon by a pusher (12) in the opening direction (O) and by a contact pressure spring (11) in the closing direction. The two contacts are closed in the connected state, and in the event of a short circuit, the contact bridge is pushed in the opening direction thereof and the pusher is moved into its trigger position in which it acts on the contact bridge in order to open same. Said switchgear is also provided with an electromagnetic tripping device (13), the armature of which releases the latching position of a switch latch (15) in the event of a short-circuit, such that the switch latch maintains the pusher (12) in the trigger position thereof by means of an actuating lever (17) which lags in relation to the pusher (12) and moves from the idle position into the disconnected position thereof. The contact bridge (7) is thereby permanently held open against the force of the contact pressure spring (11). The installation switchgear (1) comprises a control slide (30) mounted in such a way that it can be displaced between a release position and a locking position and, in its locking position, maintains the pusher in the trigger position thereof. The movement of the actuating lever from its idle position into its disconnected position causes the control slide to move from its locking position into its release position such that the pusher (12) is released from the trigger position thereof.
Abstract:
The invention describes an electrical switching device (1) in particular a motor circuit breaker and/or circuit breaker, at least with a rotary knob (10), which is mounted on the front face of the housing (9), for operation of at least one contact point via a switching mechanism, with the rotary knob (10) having a circular pot section (12) and a grip section (13), and being able to assume an initial position and a connected position, and being lead-sealable in the initial position. A slide (14) is mounted such that it can be moved radially in the grip section (13), can be pulled radially out of the grip section (13) when the rotary knob (10) is in the initial position, and can thus be moved from its released position to its locked position, and when in its locked position projects radially beyond the rotary knob (10). A holding wall (18) is integrally formed on the front face of the housing (9), with which the slide can be brought into contact in its locked position, thus preventing the rotary knob from being rotated from the initial position to the connected position when the slide is pulled out, and such that the slide can be lead-sealed in its locked position.

Abstract:
Disclosed is a device for determining the exhaust gas recirculation rate (AGR) of an internal combustion engine, comprising a tubular sensor unit which can be impinged upon by an exhaust gas atmosphere in a first area in an exhaust gas recirculation pipe and by an exhaust gas-fresh air atmosphere in a second area in an intake pipe of the internal combustion engine downstream from an inlet of the exhaust gas recirculation pipe. An inside of the sensor unit can be impinged upon by the exhaust gas atmosphere while an outside thereof can be impinged upon by the exhaust gas-fresh air atmosphere, or vice versa.
Abstract:
The invention relates to a method for monitoring a flow measurement for fluids. According to said method, a first measured variable, which is at least indirectly dependent on the fluid flow, such as the active pressure of fluid flow current and a second measured variable, which is at least indirectly dependent on the fluid flow and differs from the first measured variable, such as the eddy dissipation frequency against an interference body that is situated in the flow current, are simultaneously detected and/or calculated. The first and second measured variable are detected and/or calculated on the basis of an identical physical basic measuring principle and said first and second measured variable are compared.
Abstract:
In known high-temperature sensors, the operating temperature in the functional layer of the sensor cannot be accurately adjusted or measured nor exactly regulated. The novel device aims at enabling exact adjustment of the operating temperature on the entire surface of the functional layer. In order to exactly regulate the operating temperature on the entire functional layer, the heating conductor path that is disposed beneath the functional layer is structured in such a way that it comprises different partial heat resistors in the different regions by varying the length of the paths and/or the width of the heating conductor path vary from one partial section to another. Said devices are especially high-temperature gas sensors that are used in the exhaust gas of an internal combustion engine.

According to the invention, an operation program is produced which is very variable and can therefore be approved for operation in public.
Abstract:
The invention relates to a method for withdrawing blood from an extracorporeal circulation (2000) and/or a functional device (1000) which are connected or can be connected to a blood treatment device for treating the blood of a patient after completing a blood treatment session. Said blood treatment device comprises or is connected to at least one extracorporeal circulation (2000) having a line interior, and said extracorporeal circulation (2000) has at least one arterial line section (1) and at least one venous line section (3); at least one blood pump (4000) for transporting blood inside the line interior. Said method consists of the following steps: the blood pump (4000) is operated in a second direction of transport counter to the common first direction of transport during the blood treatment, a first section of the arterial line section (1) being connected to or is a second section of the venous line section (3) of the extracorporeal circulation (2000). The invention also relates to corresponding devices.
