Description

Arrangement for shielding earth rays

The invention relates to an arrangement according to the preamble of patent claim 1.

An arrangement of this kind is e.g. known from CH-PS 671 338; however, the effectiveness of this arrangement leaves something to be desired; their structure is also complex.

In the present case, the term earth rays is understood to mean all radiations that cannot be measured physically, and possibly have biological effects, for example the radiation of water veins, power lines, electrical equipment and machines, geodesic stimulation zones and other radiation that can be detected by radio aesthetes.

Radiations of this type can be detected by divining rod walkers or radio aesthetes and can under certain circumstances have a detrimental influence on living beings; The aim of the invention is therefore to create arrangements with which the effects of earth rays on humans and / or animals can be shielded or switched off.

An arrangement with which this goal is achieved is characterized according to the invention by the features stated in the characterizing part of patent claim 1.

Another embodiment of the invention is realized by the features stated in claim 2. Trials showed savings in fuel consumption, be it for a quieter driving style or for other reasons. Such an arrangement can easily be carried in motor vehicles and prevents the occupants from being influenced by radiation occurring in the vehicle, e.g. Electrosmog.

Another arrangement, which can also be used in particular in combination with the first arrangement mentioned, is characterized by the features stated in the characterizing part of patent claim 3.

Investigations showed that the influence of recognized radio aesthetes found stimulation zones could be switched off or minimized to a minimum extent that was considered harmless.

An advantageous further development of the arrangement provided for rooms, in particular if microwave ovens, hot air ovens or the like are used in these. are present, is characterized in that a series connection of a glow lamp with a series resistor or a parallel connection of two series connections, each with one as an additional device Glow lamp and a series resistor is provided, wherein the conductor to the glow lamp (s) has a connection to the earth conductor and / or

Neutral conductor of the power supply system and the conductor (s) to the

Series resistor (stand) have a connection to the phase of the power supply system.

According to the invention it is further provided that the wire made of an iron or steel alloy, preferably a resistance alloy, advantageously a CEKAS or a tungsten-containing alloy, in particular an alloy containing 15 to 25% Cr, 2 to 8% Al, Remainder iron and impurities; the diameter of the wire is advantageously 0.1 to 1 mm; the diameter of the wire winding is advantageously between 1 and 9 mm.

It was also shown that a coil with a length of 60 to 210 mm is sufficient to shield blocks of flats; longer lengths are not considered beneficial for the organism.

It is also essential that the coil is wound only in one layer or has the form of a single-layer tension spring, so that only a single coil is wound continuously or without interruptions. It was also shown that it is expedient to design the coil without a core and to provide for the coil to be free of a metallic sheath touching it and, if appropriate, to be accommodated in a preferably non-metallic housing, in particular made of wood or plastic. It is also advantageous that the adjacent turns of the

Coil touch each other, but in particular electrically non-conductive, and that an arrangement comprises only a single coil.

The coil can be connected to the earth connection either directly with the wire of the coil or with the interposition of an electrical conductor; the earth contact is made via a metallic component, e.g. via a wall plug or screw, a support plate or an earth spike. However, it is essential that the metallic platen is not placed on an insulating floor, e.g. made of wood, rubber, plastic, linoleum, carpet or the like is provided; the platen should be on concrete, tiles, pounded earth or the like. be provided in order to ensure a corresponding earth potential.

The other end of the coil is connected to the earth conductor, which either supplies the electrical installation that supplies the premises directly or via a connection or a connecting line; the connection to a socket close to the electricity meter is advantageously made; it was found that the shielding effect extended to all rooms which are connected to the earth conductor of this socket. A particularly advantageous shielding results if the procedure is carried out in accordance with the features of claims 14, 15 or 16.

An improvement in the shielding results if the procedure is carried out in accordance with the features of patent claim 17. It is particularly advantageous if the conductor coming from the coil ends in a plug, in particular a safety plug, which can be inserted into the usual sockets set in the wall; this design avoids pins that can be inserted into the sockets, since confusion between the phase and the neutral conductor can occur if this is not tested beforehand. According to the invention, it is also essential that the earth line in motor vehicles is rubber-insulated from the body, e.g. by means of a rubber hose, out of the vehicle and suspended or extended until it comes into contact with the ground while driving and / or at a standstill.

Further advantageous features of the invention result from the description, the patent claims and the drawing.

The invention is explained in more detail below with reference to the drawing. 1 shows a schematic arrangement for shielding rooms, FIGS. 2 and 3 design variants, FIG. 4 shows an additional device for shielding rooms, FIG. 5 shows an embodiment of a device for shielding rooms, FIGS. 6 and 12 arrangements for shielding of motor vehicles, FIGS. 7, 8, 9 and 10 different design variants and FIG. 11 a section through a spiral according to the invention.

Fig.l shows the principle of the present invention. A right-handed wound, core-free coil 1, which is optionally arranged in a housing made of wood or plastic, which housing 19 surrounds the coil 1 without contact, is either with one end (with a correspondingly long-wound coil wire) directly or via an electrical or Metallic connecting conductor 3 with a corresponding connection 7 connected to an earth line 5 of a socket 30 of the electrical installation system which supplies the rooms with shielding. As shown in Fig.l, the socket 30 is offset in a wall 4 and the extension 7 is the earth conductor contact one in the socket 30 insertable plug 6.

The other end of the coil 1 is either direct (in this case the coil wire is provided with a correspondingly long length) or with a further metallic connecting conductor 2 with earth potential 25, i.e. connected to a wall anchor or wall plug 13. In addition or instead of a connection to the wall 4, a contact with the ground 16 can also be provided as a connection to earth potential; for this purpose, an earth spike or a support plate 24 for ground contact is connected to the coil 1 via the line 2 shown in broken lines. As an alternative or supplement, it can be provided that the end of the coil 1 or the conductor 3 that is particularly close to the earth conductor is approached or connected to the neutral conductor N of the power supply system into the receptacle space of the socket; in Fig.l a conductor 8 is shown, which ends just before the socket 11 of the neutral conductor or is extended with a pin 10 in the socket 11. A further alternative or supplement is achieved when the conductor 3 or the corresponding end of the coil 1 is brought closer to the phase R or the socket 12 of the phase conductor R by means of a line 9; however, a connection to the phase should be avoided. It is not important per se whether the connections 7, 8, 9 are each extended with their own lines and connected to the end of the coil 1 or whether the three conductors in the plug component 6 are in contact with one another and only one line 3 is connected Coil is guided.

3 shows an embodiment in which the conductors 8 and 9 are connected by means of a web 22 which runs in front of the sockets 11, 12 of the neutral conductor N or the phase R. The connection 7 is connected to the earth line.

In principle, it should be noted that the same arrangements can be used if there is more than one phase in the plug.

The main shielding effect is achieved by contacting the earth wire; at most, an additional shielding effect is brought about by bringing the line 3 or line parts 8 and 9 connected to it to the neutral conductor N or to the phase R. The shielding effect according to the invention is also achieved in power supply systems in which the neutral conductor N is coupled or connected to the earth conductor E.

Fig.2 shows in detail a connection of the line 2 with the Wall dowel 13 or the extension of a support plate 24, which can be placed on the floor. The line 2 is with a clamp 15 or the like. connected, which is placed with the interposition of a lead layer 14 on the connecting part of the wall plug 13 or the support plate 24.

A device for shielding any residual radiation that may be present is shown in FIG. 4; this device comprises a plug which can be inserted into existing room sockets 30; This device consists of the series connection or a parallel connection of two series connections, each comprising a series resistor 26 and a glow lamp 27. It should be noted that the connections of the series resistors 26 to phase R and the connections leading to the glow lamp 27 to the Neutral conductor N or connected to the earth line; As glow lamps, conventional glow lamps for power lines can be provided, such as those e.g. in glow plug, screwdriver or the like. be used. The same applies to the series resistors 26. In order to be able to control this connection condition by the glow lamp 27 lighting up, a circuit 41 which takes into account the current flow direction can be built into the series circuit and only allows the glow lamp 27 to light up when the resistor 26 is present on the phase .

A further arrangement for shielding, which can advantageously be used in combination with the arrangement described in FIGS. 1 to 3, is shown schematically in FIG. A line 2 leads from corresponding earth potential connections, which are illustrated by 13 and 24, to the coil 1, which can be arranged in a housing 19. The other end of the coil 1 is connected via line 3 with a metal foil 23, a thin metal sheet, e.g. made of aluminum, iron, steel or the like. connected; this metal foil 23 is brought into contact with earth potential 25 by a further line 29; it may be sufficient to bring line 29 into contact with a wall or a stone floor, but it is advantageous if the same precautions are taken for line 29 as for line 2, i.e. the line is brought into contact with the earth using a wall plug.

A metal foil 23 ′ corresponding to the foil 23 shown in FIG. 10 can also be used as an additional device for the arrangement according to the invention, said metal foil being connected via a conductor 3, for example with a plug, to the Earth conductor E of the power supply system is connected.

6 shows an embodiment for shielding motor vehicles. The battery 18 of the motor vehicle 17 is connected with its pole connected to the ground 28 of the motor vehicle to one end of the coil 1 via the conductor 2. The other end of the coil 1 or the extension conductor 3 connected to the other end of the coil is led out of the motor vehicle via a rubber hose 20 and suspended so that it is in contact with the ground at least when driving. The arrangement of a rubber hose 20 is essential; the arrangement of plastic hoses reduces the effect.

For the coil former 1, it is advantageous if the turns of the coil 1 are at a mutual distance of less than 0.3 mm, preferably less than 0.2 mm, in particular less than 0.1 mm, it being expedient can, if adjacent turns of the coil touch. It was found to be advantageous to use non-plastic insulated wire; however, it is possible for adjacent turns of the coil 1 to be insulated from one another with a layer of lacquer. It has been shown that conventionally designed single-layer tension springs or spiral tension springs made of appropriate spring materials can be used as a coil or winding.

11 shows a torn section through a single-layer tension spring coil 1, as is used in arrangements according to the invention. The spring effect results from the material used. An improvement in the effect could be achieved if the

Wire of the coil is tinned or gold-plated.

It was also shown that it was possible either to extend the wire of the coil 1 and either to bring the respective ends into contact with the earth line E of the power supply system or into contact with earth potential 25 or to the two ends of the coils accordingly Head 2,3, e.g. to be attached to the copper wire, in particular with block terminals 31, and to bring them into contact with the earth line E or with earth potential 25.

It also turned out to be essential that the length of the winding or coil 1 is 60 to 210 mm, preferably 70 to 180 mm, in particular 80 to 160 mm. Windings that were too short resulted in a shielding effect that was too low; coils that were too long had an unfavorable influence due to their own radiation. It has proven to be particularly advantageous that the end of the conductor 3, which is guided, for example, in the form of a pin 10 into the socket 11 of the neutral conductor N, and / or the ends of the conductors 8, 9 which extend close to the neutral conductor N and / or close to the phase R. are arranged in a connector body 6 and are preferably welded with thermoplastic plastic in the connector body or are at least partially surrounded with thermoplastic plastic. The pins or wires 8, 9 used in conventional connector bodies 6 were surrounded with thermoplastic material and covered both in the direction of the neutral conductor N and the phase R, and on the opposite side.

The film body 23 or 23 'provided in the additional arrangement according to FIGS. 5 and 10 is preferably 0.1 to 0.8 mm, in particular 0.3 to 0.5 mm, thick and can be surrounded by a fabric covering; it is possible to arrange such film bodies below a carpet. As explained with reference to FIG. 1, one end of the coil 1 can be brought directly into connection with the neutral conductor and / or the earth line of the power supply network. However, it is already sufficient in most applications if the connecting line 3 is brought close to the neutral and / or earth conductor of the power supply network. Such an embodiment is shown in Fig.8. Advantageously, the connecting line 3 is introduced into a plug component 6, either a female or a plug component with the plugs removed, and connected there to the connections or, if the connections or plug fingers have been removed, fixed in any way. The one or two provided end (s) of the connecting line 3 are introduced at least into the central region of the plug component 6 and there, if necessary, covered with thermoplastic 37. Furthermore, a winding 36 is connected to the connecting line 3 and surrounds the end region of the plug component 6 protruding from the socket 30. The number of turns, preferably made of copper wire, can be between 10 and 50 or even more. In principle, the winding 36 can also be provided within the plug component and surround the two insulated ends of the connecting line 3. It is preferred if the electrical resistance of the coil is 5 to 150 ohms, preferably 10 to 80 ohms, in particular 10 to 30 ohms. These resistance values have been shown to be useful for an advantageous effect. In order to avoid an expansion of the coil 1 in the housing 19, it is provided that the coil or winding 1 in the housing with strain reliefs 31, preferably the block terminals connecting the coil 1 and the connecting wires 2, 3, located just in front of the housing walls, is fixed (Fig. 5). By "leading" or "approaching" a line to the earth line E and / or the neutral conductor N, there is a distance of about 0.3 to 20 mm between the conductor 3 and / or the earth conductor E or the neutral conductor N or an insertion of the conductor into the recess of the socket understood. Such a distance is also achieved if, for example, customary plugs with plug fingers cut off on the housing are used in sockets to which plug fingers or their connections in the plug housing the line (s) 3 coming from the spiral 1 is connected ( become) .

7 shows a preferred embodiment of a connection of the winding 1 to a socket 30 with a plug 6 with removed or cut plug fingers 8, 9. The line 3 to the coil 1 can be formed by two or three separate conductors, or the conductors coming from the earth connection 7, the neutral conductor connection 8 or the phase connection 9 are still connected to one another in the plug or on the way to the coil and as one only head continued.

An advantageous embodiment of the plug part consists in the use of known plugs cast in rubber or plastic or conventional plastic plugs with a corresponding number of connections, in particular with an earth conductor or earth conductor connection, in which the connector pins have been separated essentially flush with the housing or have been completely removed.

In the case of zeroed circuits, there is an approach or a connection to the earth contact and / or the neutral conductor of the socket or the power supply system with two conductors connected to the plug finger connections of the plug.

FIG. 9 shows a particularly advantageous embodiment, in which the coil end or the extension lead (s) 3 is (are) connected to a copper block 41 which in particular essentially fills the connector receptacle of the socket 30. This approximately cylindrical copper block 41 can be inserted into the socket 30 such that it is in contact with the earth connections 7 of the earth line E of the socket 30. At most, the copper block 41 can also be screwed into the socket 30 with the indicated screw 42. This is an optimal one Contacting of the earth line E or approach to the neutral conductor and / or phase given.

The floor connector 21 for cars can also be made from known, commercially available, metallic conductors, e.g. a stranded wire can be formed in a band of preferably conductive rubber or plastic sheathing, which are connected to the end of the coil 1.

12 shows an arrangement which is particularly suitable for attachment to motor vehicles. The coil 1 is arranged in a housing 13 made of silicone rubber or plastic. The ends of the recess 50 of the housing 19 can be closed, e.g. by casting, inserting or gluing plugs, lids or the like. A metallic fastening web 51, which is provided with holes 52 for fastening to the body 28, extends through the housing 19, which may be produced by injection molding or casting. One end of the coil 1 is connected to the web 51, which is possibly cast with the housing, e.g. soldered hard; the other end of the coil 1 is connected to the band electrode 21; the strap 21 or its strand is fastened in the present case with a screw 53 which is screwed into a nut 55 located in the housing 19, which is connected to the coil 1, e.g. is hard soldered. The web 51 can also be screwed to the housing 19 and is intended for connecting the coil 1 to the ground. In this way, an isolated and splash-proof arrangement e.g. take place in the engine compartment or on the underside of a body part (as indicated in FIG. 6) and the strap electrode 21 is removed and easily replaced or extended.
