Description

Tank interior cleaner

The present invention relates to an apparatus for cleaning internal surfaces of containers, in particular barrels or tanks.

Such devices are known per se. With them, the inner surfaces of the container are cleaned by means of a fluid impinging on the inner surfaces in the form of at least one fluid jet.

Typically, water may be used as the fluid with additives such as surfactants or the like. When cleaning wooden wine barrels but you use preferably taste-neutral water without additives.

Such devices typically include a pressure line extending from a water inlet of the device through the device to a nozzle region of the device having at least one nozzle hole, and a suction line extending from one

At least one suction-suction region of the device extends through the device to a water outlet of the device. The water outlet is outside the container to be cleaned anordnebar, and the nozzle region and the suction region of the device can be arranged in the interior of the container to be cleaned. As a result, water issuing from the nozzle area is blasted in the interior of the container to be cleaned on its inner walls, thereby adhering to the inner walls

Impurities are mechanically torn away and / or gradually dissolved or detached from the inner walls. The water bouncing off the inner walls, dripping or flowing down with them leads to these impurities and finally collects at the lowest point of the container. From there, the water together with the impurities is sucked in via the suction area and brought to the fluid outlet. In this way, the container inner walls are gradually getting cleaner.

In conventional devices of this type separate drives (pumps) are used for the pressure line and the suction line. The invention has for its object to simplify the structure and operation of such a device.

To achieve this object, the invention provides a device for cleaning internal surfaces of containers, in particular of barrels or tanks, by means of a fluid in the form of at least one fluid jet impinging on the inner surfaces, with a first fluid path (pressure line), which extends from a fluid inlet extending the device through the device to a nozzle region of the device having at least one nozzle hole; a second fluid path

(Suction line) which extends from a suction region having at least one suction hole of the device through the device to a

Fluid outlet of the device extends; wherein the fluid outlet can be arranged outside the container to be cleaned; and the nozzle area and the suction area of the device can be arranged inside the container to be cleaned. According to the invention, a fluid inlet to a

Fluid pressure (potential energy) and a fluid flow (kinetic energy) providing fluid source connectable, wherein during the

Cleaning operation of the device with connected fluid source both the flow energy of a fluid emerging from a nozzle hole fluid jet and the suction energy are provided at a suction hole through the connected to the fluid inlet fluid source, and wherein the

Nozzle region is formed by a nozzle head or spray head having at least one nozzle hole, preferably a plurality of nozzle holes, which is rotatably mounted multi-axially in the first fluid path and which is rotationally driven by the potential and / or kinetic energy of the fluid originating from the connectable fluid source.

When the fluid source is connected to this device, it provides both the energy for fluid transport in the first fluid path, i. in the pressure line, as well as for the fluid transport in the second fluid path, i. in the suction line.

As fluid liquids and / or gases or mixtures thereof, in particular water and / or air, but also others Liquids such as oil, can be used. For special applications, especially for cleaning wooden wine barrels, pure water can be used. Other applications can use others

Liquids or liquids with suspended, in particular abrasive solid particles (micro or nano particles) can be used. There are also applications where solid particles entrained in a gas are used.

According to a particularly advantageous embodiment of the device, the fluid source which can be connected to the fluid inlet is the only active drive element of the device, while all other elements of the device

Device passive, i. are directly or indirectly driven by the energy of the fluid source. This facilitates the handling of the

inventive device. After the nozzle area and the

Suction area have been introduced into the interior of the container to be cleaned, only this one source of fluid or energy source to be connected to the device, thus cleaning the internal

To begin surfaces of the container.

The fluid source may be a water reservoir with a water pump, a compressor for generating compressed air or simply a water reservoir higher than the device, e.g. the public supply network for water. As a fluid source, an oil tank with an oil pump, e.g. serve in the form of a gear pump.

The first fluid path can be assigned a first fluid delivery device, with which a fluid can be conveyed through the first fluid path from the fluid inlet to the nozzle region. Preferably, the first fluid delivery means is disposed within the first fluid path. In the same way, a second fluid delivery device can be associated with the second fluid path, with which fluid can be conveyed through the second fluid path from the suction region to the fluid outlet. Preferably, the second fluid conveying means is also arranged in the interior of the second fluid path. It is again particularly advantageous if both the first fluid conveying means and the second fluid conveying means by the energy, ie by the fluid pressure and / or the fluid flow rate of the through

fluid supplied to the fluid source provided, so that during operation of the device, both the flow energy of a nozzle jet exiting fluid jet and the suction energy are provided at a suction hole through the fluid inlet connected to the fluid source.

In a specific embodiment, the nozzle area is at least part of the first fluid delivery means, i. at least part of the conversion of the potential and / or kinetic energy of the fluid originating from the external fluid source into rotational energy of the nozzle head takes place in and / or at the nozzle head itself. a jet head water drive combination, i. the pulse-transmitting elements of the water drive are arranged in or on the nozzle head itself.

Conveniently, the nozzle head is a multi-part structure in which a first nozzle head part is rotatably mounted on a housing or line section of the inventive device about a first axis of rotation, and a second nozzle head part rotatably mounted on the first nozzle head part about a second axis of rotation is. The second nozzle head portion includes a plurality of nozzles, typically one to four nozzles, which are coronary,

typically along a concentric to the second axis of rotation

Circumferential direction, are arranged around the second axis of rotation around. Depending on the application, the first and the second axis of rotation to each other

arranged at right angles or at an angle smaller than 90 ° to each other.

This results in liquid jet patterns which reach the entire container inner surface or reach a portion of the container inner surface with correspondingly more beam energy. In the corona-like or along a circumferential direction on the second nozzle head part arranged nozzles, the nozzle axes may be arranged radially with respect to the second axis of rotation or with respect to the radial direction of a respective nozzle obliquely. By this alignment of the nozzles, the liquid jet pattern, ie the spray pattern, can also be influenced. The first nozzle head part contains a first bevel gear concentrically extending about the first axis of rotation. The second nozzle head portion includes a second bevel gear concentrically extending about the second axis of rotation and meshing with the first bevel gear. The first nozzle head part is rotationally driven by the energy of the fluid source and transmits this drive energy via the two meshing bevel gears on the second nozzle head part.

In order to achieve the rotary drive of the nozzle head, the nozzle head is preferably a part of a mechanical drive train, which has a first section for converting the flow energy of the fluid into

Having rotational energy of the drive train and thus in rotational energy of the nozzle head. The first nozzle head part is doing by the energy of

Fluid source rotates about this drive train and transmits this drive energy through the two meshing bevel gears on the second nozzle head part.

The above-mentioned first part or first section of the

Drive train can be designed as an impeller, as a turbine, as a reverse-rotating rotary pump, etc. Between this first section of the drive train and the rotatable nozzle head, the drive train may have a further part or further section with a transmission or reduction gear to the speed of the above the first section (impeller, turbine, etc.) registered in the drive train

Rotary movement for the rotatable nozzle head adapt.

Conveniently, the speed generated in the first section is reduced via the transmission to a lower speed for the rotatable nozzle head. As a transmission, various types of reduction gears, such as e.g. Planetary gearbox, "Harmony Drive",

Cycloidal gear, etc. can be used. These reduction gear units can both single-stage and multi-stage in the other section

(Transmission section) of the drive train may be arranged, wherein if necessary. Also different types of reduction gear units can be used mixed in a multi-stage arrangement. Alternatively, the function of the first section of the

Drive train (impeller, turbine, etc.) and the function of the rotatable nozzle head or spray head) are combined with each other, i. the impeller or the turbine, etc., on the one hand, and the nozzle head, on the other hand, are combined in one unit, wherein the nozzle channels are uniformly bent or curved in the nozzle head at least in partial regions of the radial extent of the nozzle head relative to the radial direction.

According to a further alternative, a part of the fluid flowing through the first fluid path, which supplies the flow energy necessary for the rotary drive, can be branched out of the first fluid path into a path parallel thereto, i. a first part of the fluid flowing in from the connected fluid source passes directly into the rotatable nozzle head, while a second part of the fluid flowing from the connected fluid source enters the rotatable nozzle head indirectly via the first section (impeller, turbine, etc.) described above. By adjusting the ratio of the split between the directly flowing direct fluid flow rate and the indirectly flowing and for the rotary drive providing indirect fluid flow rate can be achieved similar to the above-mentioned transmission adjustment of the rotational speed of the nozzle head. It is advantageous that the adjustment of the ratio and thus the nozzle head speed can be stepless or stepped.

In a further advantageous embodiment, the suction region is at least a part of the second fluid conveying means and is formed by a suction head having at least one suction hole, which is arranged in the second fluid path and by the potential and / or kinetic energy of originating from the connectable fluid source Fluid is suction driven.

To produce the suction for the suction head works in a particularly advantageous embodiment, the second fluid-conveying means according to the Venturi principle (jet pump with jet nozzle), which from the

connected fluid source forms the suction jet. this has the advantage that no moving parts are needed for the generation of the suction function.

Conveniently, the suction drive includes a suction line nozzle section, in which a jet nozzle (injector) protrudes, the opening in the interior of the suction line nozzle section opens in the suction direction. The

Jet nozzle is in fluid communication with a pressure line section. This fluid connection is a pressure line branch from the pressure line leading to the nozzle head (spray head). In operation, a portion of the cleaning liquid flowing to the nozzle head, preferably after having given up some of its energy for conversion into rotational energy of the mechanical drive train, enters the jet nozzle from which it discharges in the suction direction into the suction line nozzle section and there another part of its Energy for conversion into suction energy gives. It is particularly advantageous if in the pressure line downstream (downstream of the delivery) from the pressure nozzle branch leading to the jet nozzle, a shut-off device, e.g. in the form of a rotary valve (faucet) is arranged. As long as the energy-providing fluid source is connected to the device according to the invention, results in this structure of the suction drive

regardless of the position (open or closed) of the obturator a constant suction. The supply of cleaning fluid to the nozzle head, however, depends on the position of the obturator. When open

Shut-off fluid flows cleaning fluid to the nozzle head. at

closed shut-off no cleaning liquid flows to the nozzle head. In other words, when the obturator is open, both cleaning liquid is sucked out of the container interior and

Cleaning liquid is sprayed into the container interior; and if that

Absperrrorgan is to suck only cleaning liquid from the container interior, but no new cleaning liquid sprayed into the container interior.

In an alternative embodiment for generating the suction drive for the suction head, the second fluid delivery means is preferably a part of the mechanical drive train or coupled to this drive, which has a second portion for converting flow energy of the fluid into suction energy of the suction head.

This second part or second section of the drive train, like the first section described above, can be designed as an impeller, as a turbine, etc., but in the reverse arrangement, ie. the rotational energy of the drive train is converted into flow energy in the second fluid path.

Preferably have movably mounted parts, in particular rotatably mounted parts of the device between the respective part and the respective bearing a game or a gap, wherein originating from the connected fluid source and in the gap penetrating fluid as

Fluid lubrication for the rotatably mounted parts acts. Through this

Hydrodynamic bearing unnecessary further measures for

Lubrication. When a liquid containing micro or nano-solid particles is used as the cleaning fluid, the maximum particle size, i. the diameter of approximately spherical or cube-shaped particles, only a fraction, preferably less than 1/4, of this game.

Preferably, the first fluid path, i. the pressure line, and / or the second fluid path, i. the suction line, at least in a portion of the respective path straight and are adjustable in length in this rectilinear portion. For this purpose, e.g. a telescopic arrangement are provided, by means of which the total length of the pressure line and / or the suction line is adjustable. Alternatively, interchangeable,

be provided differently long suction lines, at the end of each of the suction head is arranged. In this way it can be ensured in containers of different size and / or shape that the suction head rests at the lowest point of the container interior space on the container inner wall, while the nozzle head is arranged in a central region of the container volume. Thus one reaches a practical one

complete extraction of pollutants containing Cleaning fluid and at the same time a good distribution of in the

Container interior rotating fluid jet pattern.

Preferably, the first fluid path, i. the pressure line, and the second fluid path, i. the suction line, at least in the rectilinear portion parallel to each other and are preferably concentric

arranged to each other. It is particularly advantageous if the

Pressure line has an annular cross section which extends concentrically around a circular cross section of the suction line. As a result, the power train, which also drives the two nozzle head parts of the nozzle head, more power (torque x speed) can be supplied.

Preferably, the device has a formation which is sealingly attachable to an opening of the container to be cleaned, preferably the opening, wherein both the first fluid path (pressure line) and the second fluid path (suction line) extend through the formation. Conveniently, this sealing formation contains a vent opening. This prevents that in the interior of the container too much negative pressure is created, which would make it difficult to aspirate cleaning fluid from the interior of the container or even impossible. In the vent, an air filter can be used. Preferably, the air filter is replaceable e.g. in the form of an air filter cartridge inserted in a venting channel of the sealing formation.

It is particularly advantageous if the device has three formations, by means of which it can be supported or fastened to three regions of the container, wherein preferably a first formation of the device can be fastened to the opening of the container to be cleaned and a second formation and a third formation of Device can be supported on an outer surface or an inner surface of the container. Typically, in the case of a (wine) keg, the first formation is a bunghole plug with vent hole, the second formation is an outside support e.g. in the form of an extendable support leg and the third formation as

Internal support suction pad with suction head. This will be a stable Three-point positioning of the device with respect to the to be cleaned

Container ensured.

The drive of the device according to the invention preferably contains four different movably mounted, in particular rotatably mounted assemblies and contains a total of a maximum of 30 different individual parts.

In a particularly preferred, especially for cleaning staggered stacked wine barrels suitable embodiment of the device includes the second fluid path forming suction line, which is different from the

Suction area of the device through the device through to the

Fluid outlet of the device extends, a sprung bendable

Section, wherein preferably the rotational energy transmitting drive train is also angled. The bendable portion is in its relaxed rest position, i. when there is no bending force, essentially

straight. If e.g. manually a bending force is exerted on the bendable portion, this gets into its curved-angled and cocked position. In this position, the suction line of the device in the opening of the container to be cleaned can also be introduced easily

("Threading") when there is little space in the external environment of this container opening, as is the case, for example, with staggered wine barrels.

The sprung bendable portion is preferably a hose extending inside a coil spring along the longitudinal direction of the coil spring. This elastically bendable suction line section preferably forms a bridge between two rigid suction line sections, one of which leads to the suction head and the other leads to the second fluid conveying means, ie to the suction drive. The helical spring has tightly contiguous or even touching turns with only very little play in the axial direction or no clearance of preferably less than 1/5 of the filament diameter. As a result, a high bending stiffness and thus a high buckling load is achieved, from which the bendable hose / coil spring section of the suction line is kinked. This high kink resistance of the hose / coil spring section the suction line is important for the support function effected by the suction line, ie by its suction foot.

Other advantages, features and applications of the invention will become apparent from the following, not limiting

to be understood description of embodiments of the invention with reference to the drawing, wherein:

Fig. 1A, 1 B and 1 C show a first embodiment of the invention as a perspective view, an exploded view and a sectional view, respectively; and

2A, 2B and 2C show a second embodiment of the invention as a perspective view, an exploded view and a sectional view, respectively.

In Fig. 1A, 1 B and 1 C, the first embodiment of the invention in the form of a particular suitable for wine barrels container interior cleaner as a perspective view, as an exploded view or as

Section view shown. The container internal cleaner BIR1 has a plurality of components, some of which are summarized as modules and described in the other figures, namely a Saugfuss- assembly 1, a nozzle head assembly 2, a bung-pin assembly 3, a connecting pipe assembly 4, an injector assembly 5, a

Water drive assembly 6, a support assembly 7, a handle tube piece 8, a handle 9 and a connecting line assembly 10th

In the following description of the figures, the components designated with the suffix "assembly" and the reference symbols 1, 2, 3, 4, 5, 6, 7 or 10 are also used without the suffix "assembly" for the sake of simplicity. Nevertheless, the respective module should always be meant.

In this rectilinear container interior cleaner BIR1 are the axis of the water drive 6, the axis of the Saugfusses 1 and the axis of the Connecting pipe 4 substantially on a straight line. It is particularly suitable for cleaning the inner walls of a wine barrel.

In order to carry out a container interior cleaning, this rectilinear container internal cleaner BIR1 is introduced into a container (not shown) and supplied via the water drive 6 to a water source (not shown) which supplies the drive energy for the container internal cleaner BIR1.

connected. When inserting the squeegee 1 is inserted through a bunghole (not shown) of the container into the container interior, which seeks to bring the squeegee 1 with its suction head 1 a possible at the lowest point of the container interior into abutment, so at the end of

Cleaning process, the entire cleaning water can be sucked out of the container.

When fully inserted into the container suction cup 1 is also the nozzle head 2a in the container interior. The nozzle head 2a is mounted biaxially and has for this purpose two mutually orthogonal axes of rotation. As a result, the new cleaning water sprayed in the form of water jets during the cleaning operation by the rotating nozzle head 2a can reach the entire inner surface of the container to be cleaned.

When the squeegee 1 is fully inserted, the bunghole pin 3 provided with a vent opening is in a form-fitting manner in the bunghole of the container to be cleaned.

The connecting pipe 4 is located during the

Cleaning process outside the container. Inside the

Connecting pipe 4 extends in the axial direction, a portion 13 a of a mechanical drive train 13 a, 13 b, which transmits a generated in the water drive 6 rotational movement of the water drive 6 to the nozzle head 2 a. In addition, extends in the interior of the connecting pipe 4 in the axial direction, a portion 14 a of a suction line 14 a, 14 b, the one

Fluid connection between the suction head 1 a of the Saugfusses 1 and the

Injector 5 forms. Thereby, during the cleaning operation by the negative pressure generated in the injector 5 spent cleaning water on the Suction cup 1 are sucked out of the container interior. Finally, a portion of a pressure line (not visible in FIG. 1) extends in the axial direction in the interior of the connecting tube 4 and forms a fluid connection between the water drive 6 and the nozzle head 2a. As a result, water supplied during the cleaning operation by the connected external water source can be supplied to the nozzle head 2a.

The connecting pipe 4 includes a transversely projecting from him high pressure connection nozzle 4a, through which the to the nozzle head 2a

reaching high pressure line to the line section 12 of

Bypass line 8, 9, 10, 12 is connected. The connecting pipe 4 also includes a transversely projecting from him suction connection stub 4 b, via which the reaching to the suction head 1 a suction line is connected to the injector 5.

The arranged in the interior of the connecting pipe 4 section 13 a of the mechanical drive train 13 a, 13 b is also formed as a tube so that it generated in addition to the transmission of the water drive 6

Rotary movement and the arranged in the interior of the connecting pipe 4 section 14a of the suction line 14a, 14b forms. In an axial region of the connecting pipe 4, in which the suction connection 4b is arranged, is located in the interior of the connecting pipe 4, an intermediate chamber 15 indicated, in which the pointing to the water drive 6 end portion of the suction line 14a and the drive train portion 13a axially protrudes through a fluid-tight pivot bearing (at 16). Via one or more openings 17 in this end region of the suction line 14a or of the drive train section 13a, the continuity of the suction line 14a, 14b is ensured even during operation with the drive train 13a, 13b rotating and with the opening or openings 17 rotating. The mentioned in the previous paragraph high pressure line is thus in its running in the connecting pipe 4 section through a channel with annular

Cross section between the inner surface of the connecting pipe 4 and the

Outer surface of serving as the suction line section 14a

Powertrain section 13a formed. The injector 5 forms the suction drive of the container Innereinigers BIR1. Into a suction pipe nozzle portion 5a projects a jet nozzle 5b

(Injector nozzle) whose opening in the interior of the suction line nozzle section 5a opens in the suction direction. This jet nozzle 5b is in fluid communication with a pressure line section 18 via a pressure line branch 19 from the pressure line leading to the nozzle head 2. In operation, a part of the high-pressure water flowing to the nozzle head 2 is branched off into the injector 5 and flows there into the suction line nozzle section 5a. In the pressure line section 18, a stopcock 20 is downstream of the delivery line branch 19 leading to the jet nozzle arranged downstream. When the stopcock 20 is open, water flows to the nozzle head. at

closed shut-off valve 20 no water flows to the nozzle head. When the stopcock 20 is open, both water is sucked out of the container interior and water is sprayed into the container interior; and if that

Stopcock is 20 to, only used or polluted water is sucked out of the container interior, but no fresh water sprayed into the container interior.

The water drive 6 forms the first section of the mechanical drive train, which extends from the water drive 6 via the axially extending in the interior of the connecting pipe 4 section of the drive train to the nozzle head 2a. The water drive 6 includes a 6a

indicated impeller whose output shaft is rotatably connected to the input shaft of a transmission indicated by 6b. The transmission 6b includes three planetary gear stages (not shown) for adjusting the rotational speed of the rotational movement for the rotary nozzle head 2a registered in the mechanical drive train via the impeller 6a.

The support 7 is attached to the pressure line in an area where it branches off from the pressure line branch 19 to the jet nozzle 5b. The support 7 extends substantially parallel to the connecting pipe 4 and has at its end a foot 7 a, which the curvature of the

Outer surface of a wine barrel corresponds. Together with the suction head 1 a at the end of the Saugfusses 1 and the bunghole pin 3 forms this

Support 7 with its foot 7a a stable three-point storage of the container Internal cleaner BRI1 on the container to be cleaned and in particular on a wine barrel.

The connecting line 10 forms part of the pressure line and constitutes a bypass line 8, 9, 10, 12, which as a parallel branch bypasses a section of the mechanical drive train 13a, 13b which extends axially inside the connecting tube 4. This bypass line 8 containing the connecting line 8, 9, 10, 12 opens out of the

downstream end portion of the water drive 6 out. The

Bypass then branches on the one hand into a first

Line branch, which opens into the pressure line section leading to the nozzle head 2 in the interior of the connecting pipe 4, and on the other hand into a second line branch, which opens into the leading to the Saugfuss 1 suction line section in the interior of the connecting pipe 4. This second line branch of the bypass line thus forms the above-mentioned pressure line branch 19 to the jet nozzle of the injector. 5

In Figs. 2A, 2B and 2C, the second embodiment of the invention in the form of a particular for staggered wine barrels suitable container interior cleaner as a perspective view, as

Exploded view or shown as a sectional view. The container interior cleaner BIR2 has a plurality of components, some of which are summarized as assemblies and described in the other figures, namely a Saugfuss assembly 1 ^* a nozzle head assembly 2, a bung-hole assembly 3, a connecting pipe assembly 4, an injector assembly 5, a water drive assembly 6, a support assembly 7, a connecting line assembly 10 and a bevel gear assembly 1 1.

In the following description of the figures, the components designated with the suffix "assembly" and the reference symbols 1 ^* 2, 3, 4, 5, 6, 7, 10 or 1 1 are used without the suffix "assembly" for the sake of simplicity. Nevertheless, the respective module should always be meant. In this angled container interior cleaner BIR2 are the axis of the Saugfusses 1 ^* and the axis of the connecting pipe 4 in

essentially on a straight line, while the axis of the water drive 6 is angled with respect to this line. It is particularly suitable for cleaning the interior walls of staggered stacked wine barrels.

The container internal cleaner BIR2 differs from the container internal cleaner BIR1 essentially in two points.

The first major difference is that the squeegee 1 ^* of the internal container cleaner BIR2 has a sprung, bendable one

Suction foot section 1b has.

The second essential difference is that the container internal cleaner BIR2 contains no handle tube piece 8 and no handle 9 (see Fig. 1). Instead, there is the angled

arranged water drive 6. The bending of the water from the drive 6 via the interior of the connecting pipe 4 to the nozzle head 2a extending mechanical drive train via the disposed between the water drive 6 and the connecting pipe 4 angle gear assembly 1 1

The Saugfuss 1 ^* has a sprung bendable Saugfuss- section 1 b, which contains a tube 21, which is located inside a

Coil spring 22 extends along the longitudinal direction of the coil spring. This elastically bendable suction line section 1 b of the Saugfusses 1 is disposed between the two rigid suction line sections, of which one leads to the suction head 1 a and the other to the suction, ie the injector 5 leads. In the illustrated embodiment, the sprung bendable suction line section 1 b is located between the arranged at the end of the Saugfusses 1 ^* suction head 1 a and arranged at the end of the pressure line nozzle head 2a.

The angle gear 1 1 has two mutually angled shafts 1 1 a, 1 1 b, of which one 1 1 a is rotatably connected to the downstream output shaft of the water drive 6 and the other 1 1 b with the section 13 a of the mechanical drive train is rotatably connected, which extends in the interior of the connecting pipe 4 in the axial direction to the nozzle head 2. The angled mechanical drive train thus formed transmits the rotational movement generated in the water drive 6 from the water drive 6 to the nozzle head 2a.

Since the nozzle head assembly 2, the bung-punch assembly 3, the connection-pipe assembly 4, the injector assembly 5, the

Water drive assembly 6, the support assembly 7 and the

Connecting line assembly 10 are contained in both the rectilinear container interior cleaner BIR1 and in the angled container interior cleaner BIR2 identical, it is unnecessary at this point already given with reference to FIGS. 1A, 1 B and 1 C description of these modules.
