Circuits 19 to 27 are grouped and three. A sound strength discriminator circuit 59 is supplied to the summing circuits 28, 29 and 30. At a medium level of the sound strength of the piece of music that in FIG. 1, three are fixed. This mean level of the sound strength is then achieved by adding the products a _x · c ₂ , a ₂ · C ₁ and a ₃ · C ₃ by feeding the input signal to a control circuit 28, three products a _x · c ₃ , a ₂ · c ₂ converter circuit 60 and then to an integration and α ₃ · C _{1 of} the summing circuit 29 and three pro circuit 61 with a large time constant fed ducts ^ ₁ -Ci, O ₂ -C ₃ and O ₃ -C _{2 of} the summing scarf an integrated signal for actuating a device 30.

The circuit 59 is summing circuits, relays are fed, which are such that the switching relay 62 is not confirmed by a 65 the control valves 32, switch of the power sources for the strong, but intermittent sound, colored lighting devices and other control, but by a coherent device of the composite Wasserfontnittleren sound , e.g. B. can be controlled by a sound of a string 1.

F i g. 3 shows an exemplary embodiment for summing circuits using vacuum tubes, the anodes P ₁ and p _{2 of} the vacuum tubes V ₁ and V ₂ being connected in parallel and the inputs Z ₁ and i _{2 being connected} to the grids C ₁ and G ₂ and the total current summation the output currents from the anodes P ₁ and p _{2 is} fed to the grid G _{3 of} a vacuum tube V ₃ , so that the output variable b, which corresponds to the sum of the input variables J ₁ and i ₂ , is taken from the vacuum tube V ₃ .

It should be mentioned here that the multiplication circuit according to FIG. 2 and the addition circuit according to FIG. 3 can be formed using suitable transistors.

The output variables b _lt b ₂ and b ₃ from the matrix circuit 55 of the previous exemplary embodiment can therefore be given as follows:

In the preceding example, the input signals C ₁ , a ₂ and a ₃ , which correspond to a low, medium and high frequency band, respectively, are modified in the matrix _{circuit 55 with the command signals from the musical discriminator circuit 57} , whereby the output signals b _{l3 b 2} and b ₃ , the features of the musical piece are accentuated which accordingly be obtained. If no musical discriminator circuit is used, the command _{signals C 1} , C ₂ and c _{3 can be} replaced with output signals from other additional filter devices. The control valves 32 are controlled by an optional actuation of the valve relays 31 with the output signals b _x , b ₂ and b ₃ from the matrix circuit 55, while the colored lighting of the water fountains by optionally actuating the color relays 33, 33 'and 33 "with the aforementioned output signals which controls the connections of the colored light bulbs to the power source.

A control device for a group of water columns of the composite water features 1 consists, for. B. from a valve relay 31 to control the dynamic actuation of the water columns in the water feature and from a further color relay 33 to control the color of the lighting of the mentioned columns, which both relays are actuated by an output signal b from the matrix circuit 55. For the sake of simplicity, the description will be limited to the behavior of the control devices connected to the output signal b of the matrix circuit 55, it being noted that similar control devices, for example the control devices 31 ', 31 ", 33', 33", etc. the other output signals cn b ₂ , b ₃ , etc. from the matrix circuit 55, as in FIG. 1, are connected and the behavior of the last-mentioned control devices results from the description of the behavior of the first-mentioned control devices.

The valve relay 31 controls the power source switch of the circuit 34 with the solenoid of the water ontänregelventils 32 and actuates the solenoid coil to control the dynamic operating conditions of the water feature. The color relay 33 controls the power source switch of the circuit 35 with the

ίο colored light bulbs for colored lighting of the Fountains of water while the color of the lighting changes in the manner described below will. Since the circuit 35 should operate the light bulbs as soon as the water columns of the water feature are formed and the colored lighting should be maintained until the entire columns of water disappear, the color relay 33 is equipped with a suitable time delay device so that the Lighting switching arrangement a correct temporal

ao delay compared to the water fountain operating switchgear receives.

In order to give a variety to the tint of the colored lighting, the lighting circuit 35 comprises a set of colored incandescent lamps, for example a red lamp R, a green lamp G, a blue lamp B, a yellow lamp Y , etc., one side terminal of each of the colored incandescent lamps are connected in parallel, while the other side terminals of each of the incandescent lamps are individually connected to corresponding terminals of the color selection relays 37 and 38, which are _{actuated by the command signals C 1} and C ₂ from the musical discriminator circuit 57. The terminals 37a and 31b of the color selection relay 37 are connected to colored incandescent lamps Y and B , while the terminals 38a and 386 of the color selection relay 38 are connected to colored incandescent lamps G and R. The power source-side terminals 37c and 38c of the relays 37 and 38 are connected to each other and to a terminal on one side of the power source for the colored incandescent lamps. The terminal on the other side of the power source is connected to the color relay 33, which is equipped with a suitable time delay device, and then to the common terminal of the colored incandescent lamps, as in FIG. 1 shown. The closed circuit, which contains, for example, the incandescent lamp R , runs from the terminal on one side of the power source 36 via a fixed contact and a movable contact of the color relay 33, a red incandescent lamp R, a fixed contact 38b of the color selection relay 38 and a common terminal (movable contact) 38 c of the color selection relay 38 and back to the terminal on the other side of the power source 36. It follows that the set of colored light bulbs, for example a set in circuit 35, consisting of R, G, B and Y, through the delayed color relay 33 is actuated while a single incandescent lamp, e.g. B. an incandescent lamp R, through the color selection relay, z. B.

by the relay 38 is actuated. Each set of light bulbs in circuits 35, 35 'and 35 " for example, is chosen from light colors, calm colors and dark colors to make a suitable one Tint for the lighting of the water fountains by choosing the right set of light bulbs to effect.

When the output control signals b ', b " , etc. from these latter devices are used, matrix circuits the diversity in which the output signals from these additional filters are supplied to dynamic actuation of the water columns and devices of the matrix circuit 55. Color of the lighting is increased, so complicating - In order to modify the output command signals from the matrix visual and chromatic representations of io circuit in a similar way as the musical motifs and printouts with a modification by the output signals from the synchronized colorful and dynamic pre-musical discriminator circuit 57, so that a guide to the water features similar automatic control is obtained that from

The color control of the lighting can be done, for example, by switching dynamic operation in the following way. For a 15 columns of water and coloring the lighting consists. quiet piece of music that z. B. the impressions of the described automatic control device expresses moonlight, actuated the command signal C ₂ contributes greatly to the demonstration of water a set of colored incandescent lamps from quiet play, which correspond to a piece of music, since they color groups, such as purple colors, in connection with a Simultaneous or automatic control of a calm operation of the water columns, whereby ao dynamic operation of the water columns and a calm presentation of the water features can be achieved switching of the lighting color synchronously with. For brilliant rhythms in the piece of music, the background music is switched to c ₃ regardless of the scale, to enable one of the water features.
