I have just applied for a provisional patent on an ST design.
Application # 61526030 , Filing date 22-AUG-2011
Title: Midpoint Reversed Directionally Coupled Double Chamber Structure For The Natural Induction Of A Tornado.
This design is to good and to practical not to apply. Here is an excerpt from the application.
Description Of Preferred Embodiments
Figures 1 and 2 show the structure of the ST. The end views shown in these figures are what one would see if one were to bend up the ends of the
structure shown in the center drawings. Referring to figure 1, item 1 is one of the two chambers. Item 2 is a channel connecting the two chambers
and is responsible for the directional coupling. Item 3 is the mid reversal point where the channel (item 2) is moved form the top of the structure
to the bottom. This is shown with the hidden lines (item 2) in figure 2.
There are no dimensions shown in these figures (1 and 2) because they can very widely and the ST will work. As a starting point, the channel (item 2)
thickness should be equal to 1/6 of the chamber (Item 1) diameter. This structure will most likely be very long and very thin and will be coiled up
to make a compact unit. As can be seen, the structure is the same on either side of the reversal point (item 3). It is simply flipped over at the
reversal point. The halves have the same cross section for their entire lengths which makes it easy to fabricate through extrusion. This extrude
able material will be referred to as “Directionally Coupled Double Chamber” material or DCDC or DC^2 (pronounced DC squared). Although figures 1
and 2 shows the to halves butted together like this, they could also be connected by Ying out the ends and then connecting the Y’s together. The
Ying process will be explained in the “Tips for experimenters” section.
Figure 3 shows the air flow pattern inside the ST structure. The flow consists of 2 helical flow tornadoes. One in each chamber. The air of each
tornado is fed into the other to form a loop. This is known as a positive feed back loop.
The flow arrows (Item 3) show the longitudinal component of the helical flow it the upper chamber while item 4 shows the same for the lower chamber.
The flow arrows (Item 8) show the rotational component of the helical flow it the upper chamber while item 9 shows the same for the lower chamber.
Notice that the helical flows are the same on both sides of the reversal point (item 10). The flow arrows (Item 6), on one side of the reversal point
(item 10), shows the air flow through the directionally coupling channel transferring air from the helical flow in the upper chamber to that in the
lower chamber. The flow arrows (Item 7), on the other side of the reversal point (item 10), shows the air flow through the directionally coupling
channel transferring air from the helical flow in the lower chamber to that in the upper chamber. The flow arrows in sequence from items 3 to 6 to 4
to 7 show the path of the positive feed back air flow loop.
Referring to the illustration on the left of figure 4, the air flow arrow (item 2) is in the same direction as the tangential velocities at the top of
the rotational component flow arrows (items 1 and 3) in each chamber. Putting the coupling channel at the top with these air flows as shown here will
result in the rotational components forcing air into the channel from one side and sucking it out from the other in the direction of flow arrow Item
2. This one way forced coupling is what is being referred to as directional coupling. The illustration on the right of figure 4 shows another
example of directional coupling.
The descriptions in this document deal with two equal size round cross section chambers containing a helical flow tornado in each chamber. This is
not the only configuration for an ST. The chambers could be just about any size or shape and still allow for helical flow tornadoes to exist. If a
channel connecting these chambers is placed in the right spot then directional coupling will occur. There could be more that just two helical flow
tornado containing chambers. As long as the helical air flow in the chambers combined with the air flow through directional couplings between these
chambers results in a positive feed back air flow loop, The ST structure in question is covered by this patent.
Referring back figure 3, If the ends of the lower chamber and the ends of the coupling channels are plugged as shown with item 5, The helical flow
tornado in the upper chamber will suck in air at the input (item 2) and blow it out the output (item 1). The ST is an air pump utilizing the same
natural mechanism behind a real tornado.
