Description

TECHNICAL FIELD [0001] The present invention relates to a filter disk filter having a fiber link,

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a fiber disk filter filter apparatus, and more particularly, to a fiber disk filter filter apparatus that supports a suction unit for sucking and removing foreign substances collected on the surface of a disk filter by a polygonal link.

In general, a fiber disk filter filter device is a filtration device for filtering a fluid such as waste water or wastewater by filtering a foreign substance into a disk-shaped filter having a surface formed of a filter cloth having a fleece, In such a fiber disk filter, the foreign matter is collected on the outer surface of the disk-shaped filter, that is, on the outer surface of the filter cloth, since the filtration proceeds while the fluid flows into the disk-shaped filter. Accordingly, the fiber disk filter filter apparatus includes a suction unit for removing foreign matter collected on the outer surface of the filter cloth.

The suction unit is installed so as to suck foreign matter collected on the outer surface of the disk-shaped filter through a slit having a length in the direction from the center to the edge of the disk-shaped filter, for example, in the radial direction if the disk- That is, the suction unit causes the fluid to flow in a direction opposite to that when the disk-type filter filters fluid such as wastewater or wastewater, thereby removing foreign matter collected in the filter cloth.

The disk type filter is installed so that at least one of the disk type filters rotates by one rotation axis depending on the size of the filtration facility. When it is determined that the foreign matter collected on the surface of the disk type filter needs to be removed, The foreign object is sucked and the foreign substance is removed by the back washing method.

On the other hand, in order to simultaneously remove foreign substances from all of the disk-shaped filters, the capacity of the pump for providing the suction force to the suction unit must be very large, so that the foreign substances are sequentially removed from the plurality of disk-

However, since the plurality of disk-shaped filters are rotated by one rotation axis, the disk-shaped filters in which the foreign matter is not removed are rotated together with the disk-shaped filter from which the foreign matter is removed. Accordingly, the filter cloth of the disk-shaped filter is continuously and unnecessarily pressed by the suction unit which is not sucking the foreign substance. As described above, when the filter cloth is pressed by the suction unit, the foreign substances trapped between the flecks are squeezed and the backwashing performance may be deteriorated.

Further, in order to enhance the backwashing effect, an elastic member such as a spring is used to bring the suction unit into close contact with the surface of the disk-shaped filter.

However, when the spring for urging the suction unit against the disk-shaped filter pushes the suction unit too strongly, the suction unit strongly presses the surface of the disk-shaped filter, which acts as an unnecessary frictional resistance to the rotating disk-shaped filter. Therefore, an unnecessary load is generated in the motor for rotating the disk-type filter, and strong friction between the suction unit and the disk-type filter causes wear and tear on the filter cloth.

Also, when the suction unit is in close contact with the disk-shaped filter, the collected foreign substances are buried deeply in the flecks, so that the reverse cleaning does not smoothly proceed and the foreign matter removing effect may be lowered.

Further, the surface of the disk-shaped filter can not always maintain a uniform plane. That is, since one disk-shaped filter is formed by assembling several parts, assembly steps of the parts may be generated, and the surface of the disk-shaped filter may have irregularities due to foreign matter. And warping may occur as the disk type filter is used for a long time.

However, the conventional suction unit is uniformly adhered to the surface of the disk-shaped filter uniformly and can not cope with steps, irregularities, and bent portions of the disk-shaped filter.

Specifically, the suction unit sucks foreign matter through a slit having a length in the direction from the center of the disk-shaped filter toward the edge, and when a protruding portion of the disk-shaped filter and a part of the slit are in contact with each other The other section of the slit is spaced apart from the filter, and the foreign matter can not be effectively sucked.

On the other hand, if the suction unit is provided so as to come into close contact with the depressed portion of the disk-shaped filter due to the step, the concavo-convexity, and the warpage, foreign matter is touched by the suction unit at the relatively protruded portion of the disk- Can be reduced.

And to the same structure, element or component appearing in more than one drawing, the same reference numerals are used to denote similar features.

The embodiments of the present invention specifically illustrate ideal embodiments of the present invention. As a result, various variations of the illustration are expected. Thus, the embodiment is not limited to any particular form of the depicted area, but includes modifications of the form, for example, by manufacture.

Hereinafter, a fiber disk filter filtering apparatus 101 according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG.

1 and 2, a fiber disk filter filter apparatus 101 according to the first embodiment of the present invention includes a filtration tank 200, a disk-shaped filter 300, a support frame 400, Member 610, a second link member 620, a suction unit 500, and a pump 800.

The fiber disc filter filtering apparatus 101 may further include a motor 700, a rotating shaft 310, a hollow drum 320, and a connecting pipe 850.

3 to 5, the fiber disc filter filtering apparatus 101 according to the first embodiment of the present invention includes an elastic pressing portion 900, a support shaft 461, a support bush 471, And further includes a fixing member 481, a link hinge shaft 462, a link bushing 472, a linking member 482, a guide pin 463, a guide bush 473, and a guide engaging member 483 .

The filtration tank 200 receives the fluid to be filtered, such as waste water or wastewater. The rotary shaft (310) is rotatably installed in the filtration tank (200). The hollow drum 320 is coupled with the rotary shaft 310 or formed integrally with the rotary shaft 310. The hollow drum 320 is formed in the shape of a hollow tube, and becomes a passage through which the fluid passing through the disk-shaped filter 300, which will be described later, is moved.

The motor 700 rotates the rotation shaft 310. For example, the motor 700 may be connected to the rotating shaft 310 by a power transmitting means such as a pulley or a chain to transmit power.

The disc-shaped filter 300 is connected to the rotary shaft 310 and is rotatable together with the hollow drum 320. The disk-shaped filter 30 has a surface formed with a filter cloth having a fleece 305. The fluid to be filtered, such as wastewater or wastewater, flows into the disk-shaped filter 300 and is filtered by the filter cloth installed in the disk-shaped filter 300. That is, foreign matter contained in the fluid is filtered on the surface of the disk-shaped filter 300. The fluid filtered while passing through the disk-shaped filter 300 moves along the inside of the hollow drum 320 and is discharged to the outside of the filtration tank 200.

2, the disk-shaped filter 300 is circular, but the first embodiment of the present invention is not limited thereto. That is, the disk-shaped filter 300 may be polygonal. For example, the disk-shaped filter 300 may have a hexagonal shape.

In addition, the disk-shaped filter 300 may be installed so that at least one of the disk-shaped filters 300 is rotated by one rotation axis 310, depending on the size of the filtration facility.

The suction unit 500 removes the foreign matter collected on the surface of the disk-shaped filter 300, and the pump 800 provides the suction unit 500 with the suction force necessary for removing the foreign matter.

Specifically, the suction unit 500 includes a body portion 550 and a suction bar 510. The body portion 550 is connected to the pump 800 through a connection pipe 850. The suction bar 510 is connected to the main body portion 550 so as to face the disc shaped filter 300 and extends in the direction from the center to the edge of the disc shaped filter 300, for example, when the disc shaped filter 300 is circular And includes a slit 517 having a length in the radial direction. In addition, the suction bar 510 may include a shape curved convexly toward the disk-shaped filter 300 about the slit 517. That is, the suction bar 510 may include a shape that is spaced apart from the disk-shaped filter 300 as the slits 517 are moved up and down.

As described above, the suction unit 500 is installed to suck foreign matter collected on the outer surface of the disk-shaped filter 300 through the slit 517 having a length in the radial direction of the disk-shaped filter 300. That is, the suction unit 500 allows the fluid to flow in the direction opposite to the direction in which the disk-shaped filter 300 filters fluid such as wastewater or wastewater, thereby removing foreign matter collected in the filter cloth.

Further, the suction unit 500 may be provided on each of the plurality of disk filters 300, one on each side. That is, the suction unit 500 can be installed twice as many as the plurality of disk filters 300. When it is judged that it is necessary to remove foreign matter collected on the surface of the disk-shaped filter 300, foreign substances are removed through the suction unit 500 while rotating the rotating shaft 310, The capacity of the pump 800 for providing the suction force to the suction unit 500 must be very large in order to simultaneously remove the collected foreign substances. Thus, the foreign substances can be sequentially removed one by one without removing the foreign substances collected in the plurality of disk-shaped filters 300 at the same time. That is, the pump 800 may sequentially provide suction force to one or more of the plurality of suction units 500. Further, the pump 800 may be composed of one or a plurality of pumps. When a plurality of pumps 800 are used, a plurality of pumps 800 may operate simultaneously or a plurality of pumps 800 may operate sequentially.

In addition, in the first embodiment of the present invention, the disk-shaped filter 300 can rotate in the top-down direction with respect to the portion in contact with the suction unit 500. However, the rotational direction of the disk-shaped filter 300 can be changed according to the installation position of the motor 700 and the installation position of the suction unit 500. [

The support frame 400 is installed inside the filtration tank 200 so as to face one surface of the plurality of disc-shaped filters 300. The support frame (400) supports the suction unit (500). That is, the support frame 400 may be provided in the same number as the suction unit 500 or may be provided to support the two suction units 500 with one support frame 400.

In addition, in the first embodiment of the present invention, the support frame 400 may include an installation slot 409 having a length in the same direction as the rotation axis 310 of the disk-shaped filter 300.

The first link member 610 is rotatably coupled to the support frame 400 at one side. At this time, the first link member 610 is rotatably coupled to the mounting slot 409 of the support frame 400. One side of the second link member 620 is rotatably coupled to the other side of the first link member 610. The other side of the second link member 620 is engaged with the main body portion 550 of the suction unit 500.

Both sides of the suction unit 500 are each suspended on the support frame 400 through a pair of first link members 610 and a pair of second link members 620. Therefore, both longitudinal ends of the suction unit 500 can have different motions. That is, the first link member 610 and the second link member 620 that support one side of the suction unit 500 are rotated differently from the first link member 610 and the second link member 620 that support the other side, Can operate.

Specifically, the first link member 610 includes a hinge hole 615 serving as a rotation center of one side of the second link member 620, a second link member 620 spaced from the hinge hole 615 in the other end direction, And a guide elongated hole 619 formed to be elongated in a tangential direction with respect to the rotation direction or the rotation direction of the guide plate 619.

The link hinge shaft 462 is coupled to one side of the second link member 620 and can be rotatably inserted into the hinge hole 615 of the first link member 610.

The guide pin 463 is spaced from the link hinge shaft 462 in the direction of the suction unit 500 and is coupled to the second link member 620 and is inserted into the guide elongated hole 619 of the first link member 610 . The guide pin 463 may be used to limit the tilting angle of the suction unit 500. That is, the second link member 620 rotates about the link hinge axis 462 by the distance that the guide pin 463 flows in the guide slot 619, so that the suction unit 500 can be tilted.

The link bush 472 is inserted into the hinge hole 615 of the first link member 610 and the link hinge shaft 462 can be inserted therein. The link bushing 472 can rotatably fix the link hinge shaft 462. [

The guide bush 483 is inserted into the guide elongated hole 619 of the first link member 610 and the guide pin 463 can be inserted therein. The guide bush 483 can support the guide pin 463 so that it can flow in the guide slot 619.

The link engagement member 482 can engage the link bush 472 with the hinge hole 615 of the first link member 610. [ The guide engaging member 483 can support the guide bush 473 so as not to be detached from the guide elongated hole 619 of the first link member 610.

Further, the support bush 471 can be inserted into the installation slot 409 of the support frame 400. The support shaft 461 is engaged with one end of the first link member 610 and is rotatably inserted into the support bush 471. The fixing member 481 can fix the supporting bush 471 in one area of the installation long hole 409. [ That is, in the state where the support shaft 461 is rotatably inserted into the support bush 471, the support bush 471 is fixed to one region of the attachment slot 409 of the support frame 400 by using the fixing member 481 Can be fixed.

The mounting elongated hole 409 of the support frame 400 can be used to adjust the position of the suction unit 500 in contact with the disk shaped filter 300 by its own weight when the suction unit 500 is installed. The suction unit 500 can be rotated about the support shaft 461 while the support shaft 461 is fixed by using the support bush 471. That is, the position of the supporting bush 471 can be fixed by using the fixing member 481 at a position where the suction unit 500 contacts the disk-shaped filter 300 by its own weight.

In one example, the support shaft 461, the link hinge shaft 462, and the guide pin 463 may be bolts, and the fastening member 481, the linkage member 482, and the guide engagement member 483 may be bolts, Lt; / RTI > The support bush 471, the link bush 472, and the guide bush 473 may be hollow cylinders.

Thus, the suction unit 500 can rotate about the support shaft 461, and can rotate at a predetermined angle also on the link hinge shaft 461. [ That is, according to the first embodiment of the present invention, the suction unit 500 is suspended by the support frame 400 by a two-bar link.

Accordingly, the suction unit 500 is in contact with the disk-shaped filter 300 by its own weight, but the support frame 400 supporting the suction unit 500 and the first link member 610 and the second link member 620 The interval between the suction unit 500 and the disk-shaped filter 300 can be adjusted depending on the situation.

In addition, both longitudinal ends of the suction unit 500 can have different motions, so that both longitudinal ends of the suction unit 500 can be inclined so as to have different distances to the disk-shaped filter 300 have.

The elastic pressing portion 900 can elastically press the first link member 610 in the direction of the disk-shaped filter 300. Specifically, the elastic pressing portion 900 includes a first pressing support bar 940, a second pressing support bar 960, and a pressing elastic member 980. The elastic pressing portion 900 may further include a spring guide 970, a tension adjusting plate 930, and a tension adjusting bolt 950.

The first pressing support bar 940 may extend from the support frame 400 in the direction of the suction unit 500. [ The second pressing support bar 960 may extend from the first link member 610 and one side may be positioned between the one side of the first pressing support bar 940 and the disk-shaped filter 300.

The pressing elastic member 980 is interposed between the first pressing support bar 940 and the second pressing support bar 960 so as to press the first pressing support bar 940 and the second pressing support bar 960, Can be elastically pressed in directions away from each other. Accordingly, the elastic pressing portion 900 can finally elastically press the suction bar 510 of the suction unit 500 toward the disk-shaped filter 300.

Further, the pressing elastic member 980 may be a spring. However, the first embodiment of the present invention is not limited to the above, and various elastic members known to those skilled in the art can be used as the pressing elastic member 980.

The spring guide 970 is provided on one side of either the first pressing support bar 940 or the second pressing support bar 960 to support the pressing elastic member 980. That is, the spring guide 970 guides the contraction and extension of the pressing elastic member 980 so that the pressing elastic member 980 does not separate from the correct position.

The tension regulating plate 930 is opposed to one side of the pressing elastic member 980 supported by the spring guide 970. The tension adjusting bolt 950 passes through one side of the first pressing support bar 940 or the second pressing supporting bar 960 and is engaged with the tension adjusting plate 930 and presses the pressing elastic member 980, Can be adjusted. That is, by controlling the degree to which the tension regulating plate 930 compresses the pressing elastic member 980 through the tension adjusting bolt 950, the pressing elastic member 980 elastically presses the first link member 610 You can control the force.

The elastic pushing unit 500 may be configured such that the suction bar 510 of the suction unit 500 which is placed in contact with the disc filter 300 by its own weight exerts an external impact or a specific protrusion It is possible to prevent the disk-shaped filter 300 from being separated too easily from the disk-shaped filter 300 due to foreign substances of a predetermined size or other steps formed on the surface of the disk-shaped filter 300. Here, the steps generated on the surface of the disk-shaped filter 300 will be described. For example, when one disk-shaped filter 300 is assembled with various parts, assembly steps of the parts may be generated, Depending on the shape, a part of the surface of the disk-shaped filter 300 may not be flat. Also, warping may occur as the disk-shaped filter 300 is used for a long time. Due to the shape of the disk-shaped filter 300, it may occur that the suction bar 510 of the suction unit 500 is caught by the step of the disk-shaped filter 300 and moves away from the disk-shaped filter 300 instantaneously .

Even when the support frame 400 and the disk-shaped filter 300 are not installed horizontally due to various reasons due to defects during manufacturing, the elastic pressing part 500 can be easily removed from the suction bar 510 of the suction unit 500 The contact of the disk-shaped filter 300 can be maintained. Here, the case in which the support frame 400 and the disk-shaped filter 300 are not horizontally installed will be described in detail with reference to FIG. 7 to FIG.

With this structure, even when the surface of the disk-shaped filter 300 is not flat, the fiber disk filter filtering apparatus 101 according to the first embodiment of the present invention can stably remove foreign matter.

Hereinafter, the operation principle of the fiber disk filter filtering apparatus 101 according to the first embodiment of the present invention will be described in detail with reference to FIGS. 6 to 10. FIG.

As shown in Fig. 6, when the frame forming the disk-shaped filter 300 is deformed due to a defect in manufacturing, long-term use, or a portion where the frame and the frame are engaged are displaced, The surface of the substrate may not be maintained flat and a step may be generated.

For example, when a plurality of parts are combined to form one disc-shaped filter 300, an assembling step may be generated at a joint portion between the respective parts, so that a step may be generated on the surface of the filter fabric.

However, according to the first embodiment of the present invention, even when deformation occurs in the frame forming the disk-shaped filter 300 as described above, the support shaft 461 and the link hinge shaft 462 rotate, The distance between the suction unit 500 and the disk-shaped filter 300 can be adjusted while moving the unit 500 in the direction away from or in the direction away from the disk-shaped filter 300 corresponding to the step formed on the surface of the filter cloth.

Therefore, since the distance between the suction unit 500 and the disk-shaped filter 300 is adjusted while the suction bar 510 opposed to the disk-shaped filter 300 is kept parallel to the disk-shaped filter 300, The suction unit 500 can stably remove the foreign matter collected in the disk-shaped filter 300.

7, the thickness protruded from the surface of the disk-shaped filter 300 due to the thickness of the foreign matter M collected in the disk-shaped filter 300 or the shape of the disk-shaped filter 300, A pair of first link members 610 and a pair of second link members 620, which support both sides of the suction unit 500, are provided on both sides in the direction from the center to the edge of the filter 300, The suction bar 510 of the suction unit 500 may be inclined in the left and right direction to have a tilt? 1 by rotating the supporting shaft 461 and the link hinge shaft 462 at different angles with respect to each other. For example, when one disk-shaped filter 300 is formed by assembling several parts, assembly steps of the parts may be generated, and the surface of the disk-shaped filter 300 may have irregularities depending on the shape of the parts . Also, warping may occur as the disk-shaped filter 300 is used for a long time. Therefore, due to the shape of the disk-shaped filter 300, the thickness protruding from the surface of the disk-shaped filter 300 can be diverted toward the edge from the center of the disk-shaped filter 300.

The thickness of the foreign matter C protruding from the disk-shaped filter 300 toward the suction unit 500 or the thickness of the foreign material C protruding from the disk-shaped filter 300 toward the suction unit 500 can be reduced when the foreign substance M is sucked and removed by the suction force of the pump 800. [ The suction unit 500 is inclined to keep the contact with the foreign matter M captured by the disk-shaped filter 300 as much as possible even when the thickness protruded from the surface of the disk-shaped filter 300 is uneven The foreign matter M can be stably removed. That is, due to the thickness of the foreign matter C protruding from the surface of the disk-shaped filter 300 toward the suction unit or the shape of the disk-shaped filter 300, the thickness protruded from the surface of the disk- It is possible to minimize the phenomenon that the suction unit 500 can not suck the foreign matter M because the clearance between the foreign matter M and the foreign matter M is increased.

As described above, according to the first embodiment of the present invention, when the pump 800 does not provide the suction force, the suction unit 500 is brought into contact with the disk-shaped filter 300 by its own weight, The suction unit 500 can be easily moved in a direction away from the disk-shaped filter 300. [0064] As shown in FIG. Therefore, it is possible to minimize the phenomenon that the suction unit 500 crushes the foreign matter M captured by the disk-shaped filter 300 or causes friction with the disk-shaped filter 300.

When the elastic pressing portion 900 presses the suction unit 500 toward the disk filter 300, the surface of the disk filter 300 is not flat and a step is generated on the surface of the disk filter 300, The suction bar 510 of the suction unit 500 is temporarily caught by the stepped portion so that the partial or entire portion of the slit 517 of the suction bar 510 can not come into contact with the segment disc type filter 300 And can be prevented from being separated.

Since the suction unit 500 can perform various motions through the first link member 610 and the second link member 620 when the pump 800 provides the suction force, The distance between the suction unit 500 and the disk-shaped filter 300 is adjusted in a state in which the slit 517 of the disk-shaped filter 510 and the surface of the disk-shaped filter 300 intersect each other, that is, As well as the suction bar 510 of the suction unit 500 may be inclined in the left and right direction to have a tilt? 1. Therefore, the suction unit 500 can stably remove various foreign substances M collected on the surface of the disk-shaped filter 300. [

Therefore, it is possible to prevent the suction bar 510 of the suction unit 500 from pressing the disc-shaped filter 300 too hard, thereby causing frictional resistance or damaging the filter cloth wrapping the surface of the disc-shaped filter 300.

In addition, the support frame 400 and the disk-shaped filter 300 should be installed in parallel.

However, as shown in FIGS. 8 and 9, during the fabrication and installation of the fiber disk filter filter apparatus 101, the support frame 400 may not be installed parallel to the disk-shaped filter 300.

Specifically, as shown in Fig. 8, the supporting frame 400 is erroneously installed, the supporting frame 400 and the disk-shaped filter 300 are not parallel to each other and have a tilt? 2, The disk-shaped filter 300 may be erroneously produced or deformed, so that the support frame 400 and the disk-shaped filter 300 may not be parallel and have a tilt? 3.

Even in such a situation, according to the first embodiment of the present invention, a pair of first link members 610 and a pair of second link members 620 supporting both sides of the suction unit 500 Since the suction bar 510 of the suction unit 500 can be inclined in the left and right direction and tilted by rotating the support shaft 461 and the link hinge shaft 462 at different angles with respect to each other, The pair of first link members 610 and the pair of second link members 620 can correct the installation direction of the support frame 400 that is not installed in parallel with the support frame 400.

Therefore, the suction unit 500 can stably remove the foreign matter collected in the disk-shaped filter 300. [

In the conventional fiber disk filter filter apparatus, when the support frame and the disk-shaped filter are not installed parallel to each other, the support structure for supporting the suction unit has a low degree of freedom in operation, And the clearance must be generated. As a result, the foreign matter trapped in the disk-shaped filter can not be effectively removed.

9, the support frame 400 is properly installed in a direction perpendicular to the rotation axis 310. However, even when the disk-shaped filter 300 coupled to the hollow drum 320 is bent, A pair of first link members 610 and a pair of second link members 620 that support both sides of the link shaft 500 are disposed at angles different from each other about the support shaft 461 and the link hinge shaft 462, The suction bar 510 of the suction unit 500 can be inclined in the left and right direction to have a tilt? 3, so that the angle at which the disk-shaped filter 300 is bent can be defined by the pair of first link members 610 and 610, The pair of second link members 620 can correct.

Therefore, the suction unit 500 can stably remove the foreign matter collected in the disk-shaped filter 300. [

As shown in Fig. 10, a pair of second link members 620 are respectively coupled to both sides of the suction unit 500, and due to manufacturing defects or deformation due to long-term use, The axial line connecting one side of the suction pipe 620 may not be parallel to the suction bar 510.

As described above, even when a pair of second link members 620 directly supporting the suction unit 500 are twisted, the first link member 610 can correct it, and therefore, the pair of first link members 610 may be parallel to the suction bar 510. In this case,

Specifically, due to manufacturing defects or deformation due to long-term use, the second link member 620 is twisted so that the first axis of rotation ax1 between the pair of first link members 610 and the support frame 400, Even when the second axis of rotation ax2 between the pair of first link members 610 and the pair of second link members 620 is not parallel to the first axis of rotation ax1 and the suction unit 500, The suction surface SP of the suction muffler can maintain parallelism.

Therefore, the suction unit 500 can effectively remove foreign matter collected in the disk-shaped filter 300. [

Hereinafter, a second embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 11, in the fiber disk filter filter apparatus according to the second embodiment of the present invention, the support frame 400 includes a round support hole 408. The fiber disk filter filter includes a support shaft 461 coupled to one end of the first link member 610 and inserted into a support hole of the support frame 400 and a fixing member 481 for fixing the support shaft 461, (Shown in FIG. 3).

According to the third embodiment of the present invention, the overall configuration of the fiber disk filter filter device can be simplified and the installation time can be shortened.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. will be.

It is therefore to be understood that the embodiments described above are to be considered in all respects only as illustrative and not restrictive, the scope of the invention being indicated by the appended claims, It is intended that all changes and modifications derived from the equivalent concept be included within the scope of the present invention.
