Abstract: The switching device (1) has a presence indicator (10) which can be influenced from the outside, a switching amplifier (11) following the presence indicator (10), an electronic switch (12) which can be controlled by the presence indicator (10) via the switching amplifier (11), and a feed circuit (13) for representing the feed voltage for the presence indicator (10) and for the switching amplifier (11), in which the switching amplifier (11) exhibits an output stage with a drive transistor and an output transistor following the drive transistor. The invention ensures that the output transistor of the output stage of the switching amplifier (11) always only consumes the required drive current due to the fact that the output transistor is associated with an auxiliary transistor, an auxiliary resistor and a voltage-increasing element and that the collector of the auxiliary transistor is driven by the drive transistor, the auxiliary resistor is connected, on the one hand, to the emitter of the auxiliary transistor and, on the other hand, to the base of the output transistor and the voltage-increasing element is connected, on the one hand, to the base of the auxiliary transistor and, on the other hand, to the collector of the output transistor. <IMAGE>

IPC: G01D5/22
Filed: 1990-03-14
Granted: 1991-06-13
Abstract: A voltage comparator, to set a desired position, compares the voltages produced by the respective magnetic coils of the sensor head and the external object with a reference voltage and from the result of the comparison gives a dependent output signal. The current supply unit alternately and repeatedly feeds a current through only one of the two magnetic coils (L1, L2) which, on one side, are connected together and are connected respectively in a series with a common resistor (R2). A measurement voltage (A) drop at the common resistor is supplied to the voltage comparator (4), a reference input(+) of which receives a constant reference voltage (B) for the respective voltage of comparison. The comparator output signal (C or Va) is changed over always to a positive or a negative level, if the measurement voltage has reached the reference voltage. The current change over between the coils results in response to the change over of the output signal level of the voltage comparator. ADVANTAGE - Lateral and height positioning of sensor head and external object to each other. Simple construction and sensor system does not require auxiliary sensors.

Granted: 1995-03-02
Abstract: A compression head of a manufacturing machine for reinforced concrete pipes has a smoothing cylinder (2) which is mounted in a rotationally fixed manner on the drive shaft (1) of said head and is intended for smoothing the inside of the concrete mixture poured into a vertical mould. On a top wall (3) of the smoothing cylinder (2) rollers (5a to 5d) for the radial compression of the concrete mixture are mounted rotatably axially parallel with respect to the drive shaft (1) and together with the latter can be driven at a predetermined speed of revolution around the axis of the drive shaft (1), the direction of rotation of the rollers being counter to that of the top wall (3). In order to prevent the concrete from being pushed in front of the rollers during the compression, but rather being compressed outwards in the radial direction in a shear-free manner, so that the steel wires of the reinforcing cage are completely covered by the concrete and between the cage and concrete stresses with corresponding cracks in the interior of the concrete do not occur, it is ensured that the top wall (3) of the smoothing cylinder (2) is mounted separately on the drive shaft (1) such that it can be rotated relative to the latter and the rollers (5a to 5d) are connected in terms of drive to the drive shaft (1) via a gear mechanism (10), the transmission ratio of which is selected such that the peripheral speed of the rollers (5a-5d) is at least equal to their speed of revolution. <IMAGE>
