FR2712143A1 - Electronic apparatus for rat extermination and elimination of cockroaches and similar vermin - Google Patents

Abstract

The invention relates to an apparatus intended for repelling or killing rats, mice, cockroaches and similar vermin. This apparatus includes a generator (1) of signals which are processed in a preamplifier (2) for driving a power amplifier (3), the output signal of which is sent to an antenna or a transducer (10) which converts the electrical signals into magnetic waves. Experiments have shown that these waves interfere with the biological guidance system of the undesirable animals, which they repel or even kill.

Description

The invention relates to an electronic device for deratization

  tion and elimination of cockroaches and similar vermin.

  The systems currently used to combat mice, rats, cockroaches and other similar vermin have shown their

  limits. The remarkable social organization and the extraordinary capacity

  The adaptation of these living species has compromised the effectiveness of new toxic molecules (anticoagulant substances causing internal bleeding). The preparations in question present significant dangers in the places intended for the storage of foodstuffs

  food or work places.

  Indeed, either by natural convection or because of

  air conditioning, toxic substances are dispersed

  in the environment, and cause deadly poisoning-

  the. A first step towards the use of substances

  chemicals came with the realization of devices using the emis-

  ion of infrasonic and ultrasonic waves.

  The main limitation of these systems is that they cause addiction in animals, and they have negative effects on the human hearing system, resulting in nausea, headache associated with loss of balance, a raise

  notable of the anxious state and even of the dangerous phenomena of "cavita-

tion "at the cellular level.

  The object of the present invention is to provide an apparatus which functions by emitting signals in the form of magnetic waves which interfere with the biological system for guiding animals in

  question, and which therefore do not have the indi-

as above.

  The apparatus according to the invention comprises an appropriately constructed signal generator, the signals thus produced

  first being processed in a preamplification stage, then amplified

  trusted to be emitted as magnetic waves. These, as already said, interfere with the biological system, to cause the

  more often remoteness, even death.

  The invention that we have just outlined will be better

  understood on reading the detailed description below, referenced

  this in the accompanying drawings, in which: - Figure 1 is a block diagram of the apparatus according to the invention, - Figure 2 is a diagram of a preferred embodiment

of the device.

  With reference to these figures, and in particular to FIG. 1, the apparatus according to the invention comprises a generator 1 which produces the signals processed in a pre-amplifier 2, in order to be able to drive a power amplifier 3 which receives these signals and sends them to

a transducer 10.

  The transducer 10 consists essentially of a transmitting antenna adapted to transform the electrical signals into

magnetic waves.

  In FIG. 2, a diagram of an embodiment has been represented.

  preferred station of the invention, comprising an integrated circuit 4 functions

  operating as a generator and producing a signal formed by rectangular waves

  laires ("clock") at a variable frequency from 40 kHz to 200 kHz, this frequency being 160 kHz in the preferred embodiment. This signal is processed in a circuit 5 by means of a variable algorithm, comprising from 2 to "n" binary elements, called "bits". In the mode of

  preferred embodiment, we operate with a 17-bit algorithm.

  The new signal emitted by circuit 5 is subject to the frequency

  quence produced in circuit 11 whose period is between ms and 100 ms, the value adopted in the preferred solution being

  62 ms, and this frequency used to adjust the transmission power.

  The subsequent introduction of a frequency of 1 Hz produced by circuit 8 allows the timing of the output signals, at a rate

  a sequence of 4 sec. emission and 12 sec. break.

  The output signal of circuit 5, in synchronism with the algo-

  previously introduced rithm, is sent to a controlled cathode relay (5A) which has the role of adapting the impedance of circuit 5 and

the next floor.

  The output signal of the controlled cathode relay 5A is sent to a switching circuit formed by two transistors 6A and 7A which are controlled by circuit 4 and which carry the two signals alternately, taken via time constants 6

  and 7, to send them to the preamplifier 9.

  The output signals from the preamplifier 9 are sent to the power amplifier 9A. Said amplifier 9A is connected to a suitable transmitting antenna 10 which transforms them into magnetic waves. As already explained, these magnetic waves interfere with the biological guiding system of animals, in particular mice, rats, cockroaches and similar vermin, and cause the escape of these

  animals and in some cases their death.
