Device for reporting the end of a milking period

A device for detecting and signalling an end of a milking period in an arrangement wherein a teat cup is affixed to an udder and milk is conveyed during a given time period by a milk line connected to the teat cup, comprising means for sensing variations of the quantity of milk flowing in the milk line and providing a corresponding output signal, said sensing means including a pair of electrodes arranged to be mounted on the milk line in opposed spaced apart relationship relative to each other;

• means for indicating the end of the milking period;
• means coupled to said sensing means and said indicating means for controlling said indicating means in accordance with said output signal, said controlling means comprising a detecting circuit for generating a detecting signal in response to a variation of the quantity of the milk flowing in the milk line which is sensed by said sensing means, a time delay circuit coupled to said detecting circuit for delaying said detecting signal by a given length of time, signal generating means for providing an indicating signal to actuate said indicating means, a biasing circuit coupled to said signal generating means and said time delay circuit for providing a biasing signal in accordance with the delayed detection signal, and a driving circuit coupled to said biasing circuit for actuating said indicating means in response to said biasing signal;
• and means for supplying power to said sensing means, said controlling means and said indicating means.
