Description

The invention relates to a device for generating randomly occurring electrical Control impulses, in which the impulses are generated by rolling balls and transmitted to the to be controlled Apparatus are passed on,

Devices in which the control pulses generated by rolling balls via a relay to the Apparatus, which produces the desired, arbitrarily occurring effects, are on and known for itself. However, these are secret telegraph systems and in particular Means for preparing a lanyard for encryption and decryption swap code signals for teletypewriters using an equal number of clear and opaque spheres, which · - correspond to the number of elements in a particular Code - are mixed, after which perforations are made in the tape according to the selection are controllable. The balls of the two types are in the known device by means of a motor-driven spiral screw shaken in a receptacle, so that after this took place. Mix individually, in several rows, directly into tubular tracks and from this. - get back to the receptacle via a belt conveyor.

In contrast, the invention is above all a particularly ingenious embodiment and arrangement of the runway, which settings according to the desired size of the Arbitrariness in a wide range and thereby the use of the device for various special purposes are permitted, and in which not only the periods in, one perfect are sufficiently random, but also the pulse duration can be controlled arbitrarily.

According to the invention, a pen board having a number of rows of pens is attached to its upper End in constant and definite. A series of steel balls fed to the time intervals Roll over the pen board due to gravity, the time of the rolling of the balls over the board is arbitrary. In one embodiment of the invention, each ball is z. B. electrically via a pair Conducting rails, which closes an electrical circuit and energizes a relay which operates an electromagnetic clutch to control the apparatus. But also, one direct control of the apparatus, d. H. without relay, is possible.

The pen board must be designed in such a way that it is particularly suitable for the purposes mentioned. Although the time it takes for the balls to generate their down-device is indiscriminate

fall arbitrarily from the entry point to the mentioned facility at the bottom of the pen board is, it still corresponds to the mathematical laws of the so-called Gaussian distribution or Normal distribution. Such a distribution is determined by the average time for the fall of the Balls and the standard deviation that occurs in each case. The standard deviation is a measure of the size of the arbitrariness and a fixed property of the respective. Pen board, the respective ball and the way it is used. The standard deviation can be in a wide range be set so that it corresponds to the particular purposes by z. B. a different ball size is used, the angle of the inclination of the pen board to the horizontal is changed, another Number of rows of pins is chosen differently or the lower exit end of a labyrinth for the balls The rows of pins representing the figure are not made at right angles to the direction in which the balls fall. The pen board, whose bottom row of pins forms a right angle with the direction of fall has the lowest standard deviation Compared to pen boards in which parts of the bottom row of pens are missing or additional parts Rows of pins are added to achieve a triangular finish.

The time for the balls to fall is for them Invention meaningless. Nevertheless, the determination of these fall times, e.g. B. for 1000 consecutively falling balls, the basis for choosing a pen board for a specific task because so that the standard deviation of a table can be determined.

As a result, the time-interrupted effects have, it is important not only for the duration during which the spheres on which the electrical devices are randomly printed conductive rails remain, arbitrarily and according to 55, but this random printing must exceed the Gaussian distribution, so that not only the highs are effective, because the eye can see a repetition, periods in a perfectly sufficient way if they are present. In addition, the pulse duration is arbitrary, it was found that a complete arbitrariness is not controlled. This property can also be quite satisfactory if it just happens to result in a certain size by the selection of the 60 production of fabric surfaces with a medium density length of the electrically conductive rails or one of prints that are completely different from the other facility and also by ^T W ahl their goods are different as such.
Inclination to the horizontal can be adjusted. In such an application of the invention, the one field of application of the invention is that one obtains a new effect of indiscriminately producing yarns with thin and thick printing with the help of a small pressure roller, the places where in the production of such yarns lies transversely to the fabric web, while the web is moved forward in a certain way at one of the points at which uniform or non-uniform velocity thickenings occur along the thread.
