The invention relates to a method and device for determining the quantity of fluid discharged from a tank via a line system. To this end, the difference between the quantity of fluid contained inside the tank before fluid discharge and the quantity of fluid remaining inside the tank after fluid is discharged is calculated. In addition, a measuring device measures the quantity of fluid, which is contained inside the line system and which is taken into consideration when determining the discharged quantity of fluid.

An electric switch is provided with a support frame at which several key switch elements are individually clipped on. An actuating front piece is attached at the support frame, which is mounted at a front plate of a switching cabinet or the like. A transmission apparatus with a compression spring is provided between a pressure pin of the actuating front piece and a ram of the key switching elements. The compression spring, the ram and the pressure pin are disposed in an inner space of the support frame receiving the key switching elements. The transmission apparatus provides several individual thrust journals which are resting in the base body and which are moved against the force of the individually coordinated overthrow springs for actuating the key switch elements against the ram.

The device is used for detecting leakages of steam contained in hollow bodies, particularly in pipes (26). It is intended for tending high temperature steam conduits. The hollow body is surrounded by a thermal insulation (24) containing a measuring chamber (28). A temperature sensor (32) and a steam detector (9, 18) are disposed within that measuring chamber. Signalling apparatus announces the simultaneous presence of steam and temperature drop. When the pressurized steam contained in the hollow body or in the conduit happens to leak, it expands thereby producing a temperature drop. The sensing of both effects, i.e. the temperature drop and the presence of vapor avoids erroneous warnings.

A switching device includes two or more switching modules (7, 8, 15) with at least one switch and connection clamps (24), an actuator (16), and a transfer device (39). The transfer device (39) propagates the drive motion initiated by the actuator (16) in a direction perpendicular to the axis of the actuator (16) and transfers the drive motion to at least one switching pin (18, 19) of the switching modules (7, 8, 15). The switching pin (18, 19) is positionable axially at a distance parallel to the axis of the actuator (16).

The invention relates to a device for contacting at least one electrical conductor. A clamping contact blade can be passed against the conductor at an acute angle. The conductor can be inserted into a channel of an insulating part, which channel is bent such as to form an acute angle in relation to the conductor.

The invention relates to a sensor unit for an apparatus for preventing condensation of a gas, particularly water vapour, on a surface of an object, with a temperature measuring device for measuring an object temperature, with a dew point determination device for determining a dew point temperature of the gas in an atmosphere surrounding the object and with a regulating and control device operatively connected to the temperature measuring device and the dew point determination device and with which an adjusting device for increasing a temperature difference between the object temperature and the dew point temperature is controllable as a function of the data obtained by the temperature measuring device and the dew point determination device in such a way that a lowering of the object temperature to or below the dew point temperature is prevented. The sensor unit is inventively characterized in that the dew point determination device is constructed as a dew point sensor for the direct measurement of the dew point and the temperature measuring device is constructed as a temperature sensor operating in contactless manner. The invention also relates to an apparatus and a method for preventing condensation of a gas, particularly water vapour, on a surface of an object.
