Abstract: The apparatus is intended for disconnection of a live electrical conductor and has an enclosure (3) and two power connections (1, 2) which are passed out of the enclosure (3). A conductor section (7) which connects the two power connections (1, 2) to one another and a propellant means are arranged in the enclosure interior (4). The propellant means is used to produce an amount of compressed gas which is sufficient to disconnect the conductor section (7) when a fault current occurs. The propellant means is kept free of combustible substances and is chosen such that the amount of compressed gas which is required for disconnection can be thermally released from the propellant means by the electrical work produced by the fault current. Since explosive substances are avoided in the apparatus, the apparatus can be produced, transported, installed and maintained completely safely. After being commissioned, the apparatus is distinguished by high operational reliability.

Abstract: The pluggable electrical apparatus, formed in particular as a surge arrester (A), has an axially symmetrical housing (1) with a housing axis (7) running in the plugging direction, a flange (5) for fastening the apparatus housing (1) on a housing (30) of a high-voltage installation (H) and an axially symmetrical active part (6). In order to make it possible for this apparatus (A) to be fitted into the high-voltage installation (H) in a simple manner, the flange (5) is formed into the apparatus housing (1) and the active part (6) is mounted displaceably in the axial direction in the apparatus housing (1) and held with a prestressing force with respect to the apparatus housing (1) before a plug-in connection is formed.

Abstract: The voltage limiter is used to effectively limit short-term and long-term overvoltages. Said voltage limiter has a varistor (1) and a discharge path which can be connected in parallel with the varistor. The discharge path contains a switching point (4), which is preferably in the form of a semiconductor switch and can be loaded with an uninterrupted current, and which can be closed above a limit value of a signal which is dependent on an operating variable of the varistor (1). The varistor (1) is arranged in a first area (24) and the switching point (4) is arranged in a second area (26) of two areas (24, 26, 28) which are at an axial distance from one another in the direction of an axis of symmetry (20). Means (5) for operating the switching point (4) are accommodated in a third area (28), which is at a defined potential.

Abstract: At least one thread tension sensor for each thread is provided on a winding machine. The actual value of thread tension is measured for each thread. The actual value is compared with a specified value in a comparator device and, in the event of a deviation being determined between the actual value and the specified value, a drive motor is actuated to adjust the thread brake of the thread concerned. This arrangement allows for the maintaining of a constant thread tension by a control circuit. The thread tension sensor can be used not only to control the thread tension, but also to monitor the specified thread tension range, and as a thread break monitor.

Abstract: Arranged in the area between the winding heads (25), located closest to the winding machine (3) on one creel side, and the winding machine, is at least one thread tension sensor (9) for each thread group with the same running length (L1, L2), at which the ACTUAL value of the thread tension of a thread can be permanently measured. The ACTUAL value can be compared in a comparator device (30, 30′) with a SPECIFIED value. In the event of a deviation being determined between the ACTUAL value and the SPECIFIED value, a drive motor (20, 21) can be actuated, by means of which the thread brakes (18) of a thread group can be adjusted. The arrangement allows for the maintaining of a constant thread tension in a control circuit.

Abstract: In some operating states, supplemental additional sealing steam must be fed to the sealing-steam system of a steam turbine. The feeding of supplemental sealing steam from the live-steam line involves considerable problems. According to the invention, therefore, the sealing-steam system is connected via a feeder line to a bleed point of the superheater of the boiler, so that the temperature of the supplemental sealing steam is well below the live-steam data and, in particular, is compatible with the material temperature in the region of the high-pressure shaft seal.

Abstract: Method of measurement of the total length of a yarn formed winding material (3) running onto a wound package (1), in particular a yarn web running onto the winding beam of a winding machine. During continuous winding operation, the length is ascertained by means of a measuring roll (2) over which the material to be wound (3) is guided. During acceleration and braking procedures, slippage occurs between the material to be wound (3) and the measuring roll (2). On occurrence of slippage, the system of measurement is changed, and the length of the wound package is determined from the rotational speed of the wound package (.omega..sub.w) and the circumference of the wound package (1). The circumference of the wound package (1), as well as the increase of the wound package circumference per rotation of the wound package, are ascertained during continuous winding operation.

Abstract: Separate drive motors (30, 35) for the positioning of the warping carriage (25) in the X-, respectively the Y-direction, are provided on a cone section warping machine. In addition to that, separate servo signals for both the servo motors (30, 35) are generated, whereby not only the absolute value of the servo signals but also their relationship to one another is stored and is able to be corrected through correction values. For the correction, a program control device (62) and/or a regulator (67), respectively correction circuits (64, 66), are provided.
