in the accompanying drawings , which form a part of the specification and are to be read in conjunction therewith , and in which like reference numerals are employed to indicate like parts in the various views : fig1 is a perspective view of a fluidizing apparatus constructed according to a preferred embodiment of the present invention , with portions of the storage tank broken away for illustrative purposes ; fig2 is a schematic diagram of the fluidizing apparatus shown in fig1 ; and fig3 is a fragmentary sectional view on an enlarged scale taken generally along line 3 -- 3 of fig1 in the direction of the arrows . referring initially to fig1 and 2 , numeral 10 generally designates an apparatus for producing fluidized lime which is made in accordance with a preferred embodiment of the present invention . the fluidizing apparatus 10 includes a storage tank 12 for holding the fluid medium with which the lime is mixed and storing the end product prior to application thereof . the type , size and physical configuration of the tank are not critical ; however , it is preferable to use a tank with a hollow interior having a cylindrically shaped body portion 14 and a cone shaped bottom portion 16 . an output line 18 is attached to the bottom portion of the tank such that the hollow interior of the line communicates with the hollow interior of the tank . output line 18 extends from the bottom portion of the tank to the intake or suction side of a fluid pump 20 which is driven by a motor 22 . a manual valve 24 is located in the output line 18 between tank 12 and pump 20 . this valve is of a standard design which is well known to those of ordinary skill in the art . the output side of pump 20 connects with a &# 34 ; t &# 34 ; fitting 26 which in turn connects with two separate conduits 28 and 30 through respective elbows 29 and 31 . conduit 28 is equipped with an inductor unit that is generally designated by the numeral 32 . a manual valve 34 is mounted between fitting 26 and elbow 29 . inductor unit 32 is of a conventional construction and is best illustrated in fig3 . unit 32 has a hollow casing 32a having an inlet port 32b and an outlet port 32c . leading to connection with port 32b is a reduced size conduit 28a forming part of conduit 28 . a nozzle 33 is mounted within casing 32a and receives incoming fluid entering port 32b . nozzle 33 has an outlet 33a which is considerably reduced in diameter and which is located within casing 32a a short distance from outlet port 32c . connected with outlet port 32c is a flared conduit 28b which forms part of conduit 28 . conduit 28b gradually diverges as its extends away from its connection with port 32c . the top of casing 32a is provided with a port 32d which serves as a lime intake port . nozzle end 33a is in close proximity to port 32d to induce lime into the inductor unit , as will be explained in more detail . a tubular conduit 36 is coupled with the lime intake port 32d of the inductor unit such that the hollow inner portion of the conduit communicates with the lime intake port . conduit 36 is equipped with a valve 38 which in turn connects with a coupling 40 which serves to connect a flexible hose 41 with the inductor unit . hose 41 leads to a tank truck or the like ( not shown ). the outlet port 32c of inductor input 32 is coupled with the interior of storage tank 12 by means of conduit 28b , an elbow 42 , and a return line 43 which connects through a valve 44 with elbow 42 . return line 43 passes through the outer wall of storage tank 12 and simply terminates in an open end located within the interior area of the tank . this end of line 43 is left open so that the fluid medium which is being conveyed by the return line is capable of passing through the open end of the return line back to the storage tank . conduit 30 connects with return line 43 at a location downstream of valve 44 . a pair of mixing lines 46 and 48 branch outward from conduit 30 at spaced apart locations . mixing lines 46 and 48 enter storage tank 12 at diametrically opposite points thereon and extend upward along the inner side walls of the tank . each line terminates in a closed end and is provided with a plurality of vertically spaced discharge openings indicated at 50 . these openings allow fluid to be sprayed into the inner area of the tank when the fluid medium is being conveyed through the mixing lines . a first manual valve 52 is located upstream of the point where mixing lines 46 and 48 branch outward from conduit 30 . a second manual valve 54 is located downstream of this point . in addition , mixing line 46 is equipped with a manual valve 56 , while another manual valve 58 is included in mixing line 48 . the fluidizing apparatus can also be equipped with an auxilliary mixing line 60 . auxilliary mixing line 60 is comprised of a tubular conduit which enters storage tank 12 through the open top of the tank to provide an alternative means for introducing powdered lime into the fluid medium if inductor unit 32 becomes clogged during use . in use , a prescribed amount of fluid medium is initially placed within storage tank 12 . the amount and composition of the fluid medium is critical to the effectiveness of the finished product and is determined by the character of the soil on which the finished product is to be used . the fluid medium which is initially placed in storage tank 12 is typically comprised of a wetting agent , a suspending agent such as attapulgite clay , and water . water may be replaced with a nitrogen solution and water soluble potash may be added to the medium to enhance the effectiveness of the finished product . the fluid medium is then thoroughly mixed . to mix the fluid medium , pump 20 is started with valves 24 , 52 , 56 and 58 in an open condition while valves 34 , 38 , 44 and 54 are in a closed condition . this configuration causes the fluid medium to be drawn out of the storage tank via output line 18 and to be pumped back into the tank through tee fitting 26 , elbow 31 , conduit 30 and mixing lines 46 and 48 . the fluid medium returns to the storage tank through openings 50 in mixing lines 46 and 48 , thereby causing the fluid medium stored within a tank to be vigorously agitated by the fluid medium being returned to the tank . the vertically spaced discharge openings 50 enchance the mixing action imparted to the fluid . once the fluid medium is fully mixed , pump 20 is shut off . thereafter , valves 52 , 54 , 56 and 58 are closed while valves 34 and 44 are opened . the hose 41 from a pneumatic tank truck containing powdered lime is then coupled with coupling 40 of intake line 36 . pump 20 is then started causing the fluid medium to be drawn out of the storage tank 12 via output line 18 and to be pumped through inductor unit 32 before being returned to storage tank 12 via return line 43 . the fluid medium flowing through inductor unit 32 passes through nozzle 33 and the reduced outlet end 33a to create a vacuum within the casing 32a of the inductor unit . this vacuum or low pressure produces a suction on intake line 36 and port 32d . valve 38 is then opened and the pressure within the pneumatic tank truck is applied to hose 41 , thereby causing the powdered lime which is stored within the pneumatic tank to be drawn into the inductor unit from the tank of the truck due to the suction effect created within the inductor unit and the pressure created by the pneumatic tank truck . in this way , the powdered lime is drawn into the inductor unit 32 and is mixed with the fluid medium under pressure . this procedure continues until all of the lime in the pneumatic tank truck has been mixed . by mixing the powdered lime with the fluid medium in this manner , the problem of air pollution is eliminated . in particular , the powdered lime is mixed with the fluid medium in the closed conduit 28 , thereby eliminating the generation of dust during the mixing operation . once all of the powdered lime has been mixed with the fluid medium , valves 34 , 38 and 44 are closed while valves 52 , 56 and 58 are open . pump 20 is maintained in an active condition thereby causing the fluid medium to be drawn out of storage tank 12 and circulated back to the tank by means of mixing lines 46 and 48 . this circulatory action , in conjunction with the spray discharge through openings 50 , causes the mixture of powdered lime and fluid medium which is contained within storage tank 12 to be agitated . the mixture of powdered lime and fluid medium which is contained within storage tank 12 is pumped out of the storage tank by placing valves 44 , 52 , 54 , 56 and 58 in a closed position and placing valves 24 , 34 and 38 in an open condition . a hose from a delivery vehicle is then attached to coupling 40 of intake line 36 . thereafter , pump 20 is activated causing the mixture of powdered lime and fluid medium to be drawn out of storage tank 12 . this mixture is then pumped to the delivery vehicle through inductor unit 32 , conduit 36 , and the hose leading to the vehicle . once the entire mixture of powdered lime and fluid medium has been pumped out of storage tank 12 , the hose is disconnected from the delivery vehicle . pump 20 , however , is maintained in an active condition to pump the mixture of powdered lime and fluid medium which remains in output line 18 , fitting 26 and branch line 28 through the inductor unit 32 . passage of this material through the inductor unit 32 causes a vacuum to be created within the outer housing of the inductor unit . this vacuum draws the mixture of powdered lime and fluid medium remaining in lime intake line 36 and the hose which was connected to the delivery vehicle to be drawn back into the inductor unit thereby eliminating the chance of spillage . from the foregoing , it will be seen that this invention is one well adapted to attain all the ends and objects hereinabove set forth together with other advantages which are obvious and which are inherent to the structure . it will be understood that certain features and subcombinations are of utility and may be employed without reference to other
