DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
The present invention is a transition unit 10. The transition unit 10 is an assembly that is preferably located sub grade.
The transition unit 10 includes an elongated outer cylinder 12 that is preferably made of magnetic stainless steel. The cylinder 12 is located within a hole 14 in the ground 16 at a position vertical to the ground 16. A concrete slab 18, free of metal, is placed over a vapor barrier on well compacted sand and gravel fill 20. The slab 18 must be perfectly level and a drain sump 22 is positioned below the elevation of the slab 18 for removing water.
A base 24, supported by the slab 18, is located at the lower end of the outer cylinder 12 for supporting an inner cylinder 26. The base 24 includes four separate wings 28 that are offset at 90 degree angles from one another. Each wing 28 is preferably made of wood and the base 24 is centrally positioned within the outer cylinder 12 in order to maintain trueness. A recess 30 at the upper end of each wing provides a centering feature for locating the lower part of inner cylinder 26 precisely in place relative to the centerline 32. The centerline 32 extends axially in the outer cylinder 12 and is vertical to the ground.
A plurality of grounding rods 34 is driven to the water table 36 in order to establish a ground. Each grounding rod 34 is connected to the outer cylinder 12 by a copper braid 38 in order to ground the outer cylinder 12.
The inner cylinder 26 is preferably made of non-magnetic stainless steel and has an outside diameter of K and a length of Kx Pi. K is a variable and starting point for the configuration and manufacture of the unit 10. K represents the diameter of the inner cylinder. K is a variable and starting point for the configuration and manufacture of the unit 10. K represents the diameter of the inner cylinder. K could be in the range of 10-140 inches in diameter. A flange 40, has a width of K/Pi, and is positioned at the lower end of the inner cylinder 26 at a distance of K/2 from the lower end of the cylinder. The outside diameter of the flange 40 is K+2(K/Pi). The space between the inside diameter of the outer cylinder 12 and the edge of the flange 40 is K/4Pi. The positioning is precise and the flange 40 is preferably made of magnetic silicon steel. A plate 41 located within the cylinder 26 is aligned with a centerline 42 that extends through the flange 40 which is also at a right angle from the wall 43 of the inner cylinder 26. The outer cylinder 12 has a midpoint 44 and the inner cylinder 26 is positioned so that the centerline 42 is in alignment. The length of the outer cylinder 12 is (Kx 2Pi)+2(K/4Pi) and its inside diameter is K+2(K/Pi)+2(K/4Pi).
Struts 48 are positioned between the inner wall of the outer cylinder 12 and the outer wall of the inner cylinder 26 for arranging the inner cylinder 26 in a perfectly upright position. The struts 48 are preferably made of wood and are spaced equally around the perimeter of the inner cylinder 26. Copper wire braids are a cable connection 50. The cable connection 50 grounds the flange 40 to the outer cylinder 12.
A canister 52 for housing substances is located within the inner cylinder 26. The canister 52 is preferably made of aluminum alloy and has a diameter that is slightly smaller than the inside diameter of the inner cylinder 26 so as to provide a loose fit there between. The canister 52 has an open top that is recessed below the top of the inner cylinder 26. Pads or bumpers made preferably of neoprene are secured to the bottom of the canister 52 for aiding in the insertion of the canister 52 into the inner cylinder 26 and on top of the plate 41.
With reference to FIGS. 3 and 4, the canister 52 can be easily removed to and from the transition unit 10 by a hoist assembly 54. The hoist assembly 54 allows the canister 52 to be removed and substances 56 to be put into the transition unit 10 for processing. A top panel 58 that is preferably made of wood extends over the opening of the outer cylinder 12. An access hole 60 in the top panel 58 can be accessed by removing cover 62. Once the cover 62 is removed, the hoist assembly 54 can be lowered within the outer cylinder 12 to facilitate maneuvering of the canister 52.
The hoist assembly 54 includes cables 64 that in turn are connected to a plate 66. Suspension bars 68 are pivotally connected to the plate 66 at one end, and at the other end to linkage rods 70. Lifting bars 72 extend outwardly from the suspension bars 68 for engaging an inner surface of the canister 52. The inner and outer movement of the lifting bars 72 is effectuated by a control rod 74 that extends vertically through the plate 66. A handle 76 connected to the control rod 74 allows an operator to lift the rod 74 into a disengaged position as shown in FIG. 3, or to an engaged position as shown in FIG. 4. When the hoist assembly 54 is in the engaged position, the canister 52 can be maneuvered to or from the transition unit 10. The transition unit 10 can be reused repeatedly by removing the canister 52 from the inner cylinder 26. Thus, the canister 52 is not permanently placed into the ground 16. This flexibility allows the transition unit 10 to be used over and over again such that a variety of substances 56 can be placed in the canister 52. The processed substances 56 can be solid or liquid. The canister 52 is operable of being repeatedly removed from the inner cylinder 26, filled with a substance 56, and relocated within the inner cylinder 26.
FIG. 5 depicts an alternative transition unit 100. The transition unit 100 is designed substantially the same as the transition unit 10 as previously discussed, except that the transition unit 100 is operable to specifically handle fluids. The transition unit 100 includes an outer cylinder 12, a slab 18, grounding rods 34, a base 24, and inner cylinder 26 and a canister 52. However, the new aspects are the fluid means 102 that transports fluid to and from the transition unit 100. An inlet 104 provides a supply of fluid, or even a gas, into the transition unit 100 by means of piping. Connectors 106 allow for quick disconnect of the fluid lines from the canister 52. Within the canister 52 are circulation lines 108 that pass the incoming contaminated fluids through a field 110. An outlet 112 transports fluid from the transition unit 100 to where it can now be used. It will be appreciated that the transition units 10 and 100 can be modified to handle other substances by modifying their size and configuration.
The description of the invention is merely exemplary in nature and, thus, variations that do not depart from the gist of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
