摘要： A method for delivering a fluid using a centrifugal pump (11). Machines (1, 6) and/or apparatus (3, 8), which influence the pressure and/or the temperature of the fluid, are disposed upstream of the centrifugal pump (11). At the inlet to the centrifugal pump (11), the fluid is regulated to achieve a specific entry state. According to the invention, the entry state of the fluid is regulated by using the machines (1, 6) or apparatus (3, 8) such that, in the centrifugal pump (11), the fluid only takes on states in which the compressibility factor of the fluid has already reached or exceeded the minimum thereof.

摘要： The invention relates to a lighting fixture (1) which comprises at least one lighting fixture housing (2) and a cover (3) and which is constructed particularly as a safety and/or emergency exit light and/or as an explosion-proof light. A light is held by a clamp connection (5) at the lighting fixture housing, and at least one auxiliary electrical device (6) into the light is disposed at the lighting fixture housing. The lighting fixture can be expanded with a lower expense for the installation and with all explosion-protection measures observed, by virtue of the lighting fixture housing (2) having conductor rails (7) for supplying electricity to the light and to the auxiliary electrical device, where the auxiliary electrical device is constructed as a plug-in module which can be plugged onto the conductor rails.

摘要： An electrical socket, in particular for explosion-prone areas, includes a socket insert, which is supported in a socket housing such that it is adapted to be rotated between off- and on-positions and in which a substantially pin-shaped locking element is supported such that it is displaceable between a pressed-down blocking position and a release position in which it projects beyond the socket insert. In the release position of the locking element, the socket insert is rotatable between the off- and on-positions. In order to improve an electrical socket of this type in such a way that it can also be connected to other plugs on certain occasions, the substantially pin-shaped locking element is defined by at least one removable locking component and a blocking component, which are arranged on top of one another in the socket insert, with the locking component projecting beyond the socket insert in the release position.

摘要： A constant voltage or constant current output circuit is disclosed which can be operated with input voltages which fluctuate sharply at nearly any frequency. A pulse width modulated (PWM) switching transistor is used with a choke inverter. The PWM switching transistor is input and output level responsive. A second transistor is connected to the switching transistor and is used to block operation of the switching transistor. The electronic device according to the invention supplies a constant output voltage even at input voltages between 70 and 264 volts and stimulates oscillation absolutely reliably even under maximum load. In addition, the device is suitable for DC and AC voltages of any frequency and merely requires a simply designed voltage regulating circuit that uses only ordinary components.

摘要： An explosion-proof LED module has at least one light-emitting diode, a heat sink connected to this and an LED cover that covers the LED at least in the emission direction. The LED cover extends into an insertion recess of the heat sink. In this insertion recess, the LED cover is surrounded by a casting compound resulting in sealing of the LED relative to an outer and possibly explosive atmosphere. As a result, an explosion-proof LED module can be provided whereby the manufacture of said explosion-proof LED module is relatively simple and possible in an economic manner in a short time from prefabricated parts. At the same time, the explosion-proof module is furthermore characterized in that sufficient cooling corresponding to the ignition protection type “intrinsic safety” and an embedding of the component according to ignition protection type “encapsulation” are given.
