Abstract: The fixed bed reactor for biological waste water treatment is provided with an intermediate base (1) carrying base nozzles (2) by means of which the fixed bed can be backwashed. The inlet (3) for the waste water is located above the fixed bed. According to the invention, aeration nozzles (21) are integrated in the base nozzles (2) by means of which aeration nozzles gas bubbles (23) can be incorporated in the upper part of the base nozzles (2), without instabilities arising. In order that a stable equal distribution of the aeration occurs everywhere in the reactor, the open cross-section in the overall inlet region of each base nozzle (2) must be dimensioned so that above the aeration nozzles (21), the waste water outlet flow does not hinder the rise of the gas bubbles (23). If this condition is not fulfilled, the situation depicted in the picture (Figure 1a) can occur. <IMAGE>

Abstract: In a method for monitoring the condition of rail switch points and for detection of premature abrasive wear-and-tear in the region of the tongue switching rail (3) of the points, the signals from at least one proximity sensor (2) in the region of the tongue switching rail (3) of the points are evaluated when the tongue switching rail is travelled upon, and the smallest measured value of the separation distance (l) during the travel is stored in memory. The smallest measured value stored in memory and at least a first limiting value for the smallest separation distance are compared with one another and, when the smallest measured value in memory exceeds this first limiting value, a warning signal is generated.

Date Mar. 4, 1993.This invention relates to a clock synchronisation circuit and a method of synchronising a clock signal with a received data signal in a digital communications system such as a burst-mode TDMA system. The clock synchronisation circuit comprises a clock for providing the clock signal having a frequency which is greater than the signal frequency of the received data signal by a predetermined amount, and logic means, such as an AND gate and divider, for logically combining the clock signal with the received data signal to provide an approximate synchronisation signal. The approximate synchronisation signal provides a synchronisation signal for the digital communications system The circuit further comprises comparing means for comparing the approximate synchronisation signal with the receive d data signal and for generating an error signal in response to the difference therebetween, and delay circuitry coupled to the clock and logic means for delaying the clock signal in response to the error signal so as to reduce the difference between the approximate synchronisation signal and the received data signal. In a preferred embodiment, the clock synchronisation circuit successively introduces delays to the clock signa in response to transitions of the synchronisation word in the received data until the approximate synchronisation signal is synchronised to the received data signal.

Abstract: In order to supply power to electronics, especially to the electronics of a differential-current protection circuit breaker which is connected via a rectifier in a three-phase bridge circuit to a three-phase network having a neutral conductor, the three-phase phase conductors (L1, L2, L3) are connected, according to the invention, via in each case one overvoltage suppressor (4 to 6), especially a varistor, to a common junction (8) which is connected to the neutral conductor (N) via a limiting element (9), preferably an additional overvoltage suppressor (7) and in particular a varistor. In the event of a pulse-like overvoltage between the conductors (L1, L2, L3, N), for example in the case of a lightning strike, one of the overvoltage suppressors and a further overvoltage suppressor or the limiting element are always connected in series in this arrangement, and the voltage spike is thus suitably limited. <IMAGE>

Abstract: A rotary bushhammering apparatus comprises a head (26, 119) having a hub (15, 115) connected for rotation to a rotary shaft (16, 112). The head (26, 119) in turn comprises a plurality of freely rotating rollers (12, 117) the axis of which is disposed radially to the rotation axis of the head, each roller having radially projecting points (14, 118) on its peripheral surface, so that on rotation of the head (26, 119), it is driven to roll on a surface to be worked, the points thus scratching said surface to be worked. A mass (20, 121) weighing on the rollers (12, 117) is supported between the rotary shaft (16, 112) and head (26, 119) so that said rollers (12,117) can exert pressure against the surface to be worked, the mass (20, 121) being prevented from rotating with the head (26, 119). Advantageously, the head (26) can be connected to the rotary shaft (16) by interposition of an articulated joint (25) enabling the free inclination of the head (26) rotation plane with respect to the rotation axis of the shaft (16). In this way, the working of the curved surfaces is permitted. <IMAGE>
