Do you have that evidence of thermite being capable of cutting through a thick, vertical girder?
Don't post the link to the patent again, that didn't support your theory. Stop going from one topic to another like a drunken squirrel and provide evidence or revise your original claim.
ETA: All this talk of jello and pancakes is making me hungry.
Just found out today that Google has a new search page for US patents.
Here's another one that might actually work for cutting something vertical, but again, it's not explicitly clear that it can do that.
Some money quotes:
Referring now to FIGS. 1, 7 and 8, any conventional holding device (not shown) such as clamps, thermite welding magnets, suction devices, or counter thrust devices may be employed to maintain the housing 2 in substantial contact with the target material 11. The holding device is provided to engage a surface of the target material 11 and to maintain stability for the housing 2 including end plates 30,31 positioned on the target material 11.
Referring again to FIGS. 1 through 3, the housing 2 of the apparatus 1 for cutting material is preferably composed of a material selected from the group consisting of high density graphite and phenolic composites. The housing 2 may be composed of any suitable material adapted to withstand generation of a thermite-based cutting flame. It will be appreciated that the housing 2 has relatively high flexural and tensile strengths which are also consistent with relatively low thermal conductivity. A housing 2 composed of mineral phenolic is preferable given its performance characteristics in the practice of the present invention. Other suitable materials which may be used to construct the housing may include, for example, graphite, polymer composite materials, and glass-filled PEEK (polyetheretherketone). Graphite, for example, generally provides a preferable degree of erosion resistance and has relatively low flexural strength and relatively high thermal conductivity.
Seems king of small though:
The nozzle 46 preferably has a length L2 of 0.3 to 0.4 inches
Here's the real goods:
It will be appreciated by those skilled in the art that the cutting apparatus of the present invention may be oriented in any angle or configuration deemed most expedient for application of the cutting apparatus to a target material to be cut.
Unfortunately, he doesn't give any more explicit descriptions of it's use, and this sounds like standard patentee "Cover all my bases in case someone thinks of something clever I didn't" language.
On the size issue again:
Referring again to FIGS. 8 and 10, in another embodiment of the present invention, a ganged apparatus 51 for cutting target material 11 is also provided in the present invention. The ganging of individual housings 61-64 to each other may be accomplished by providing a plurality of holes 32 in each of the end plates 56-60 of the housings 61-64.
.....
The ganged together nozzles 52-55 provide an extended, linear cutting action by spreading the cutting flame between adjacent nozzles 52-55 thereby cutting substantially all of the target material 11 underneath the ganged apparatus 51. Slots 23 (as shown in FIG. 8) in each end plate 56-60 facilitate the spread of the cutting flame of each housing 61-64.
But, oh, sorry, notice he slips up and mentions material "underneath" the apparatus? So maybe it won't work vertically after all.
Then he says this:
The respective nozzle channels of the housings 102,112 are positioned to be substantially opposed in order to effect a cutting action on the same target material from two opposite directions.
So, maybe it will? Hmm.....
On the issue of size again:
It will be appreciated that the dimensions of the cutting apparatus may be modified within the scope of the present invention to cut various sizes and shapes of target materials. Preferably, the cutting apparatus of the present invention may be employed, for example, to cut steel bars of up to one inch in diameter. It is believed that the diameter of a bar which can be successfully cut by the present invention is proportional to the diameter of the thermite charge employed in the cutting apparatus of the present invention. The charge diameter may range from about 0.25 to 12 inches
So, if you want to cut a large target, you'd need a similarly sized apparatus, roughly speaking.
Here we have what is probably the best candidate for your hypothesised thermite devices. It even has the benefit of having been available before 9/11. Now, can you show any such apparatus (thousands of them) on ground zero? Can you find any record of these being manufactured in that size in the needed quantities? The patent lists the company that owns the patent, perhaps you could phone them and ask about it.
The deep dark secret of the patent world is, the vast majority of patents never actually get made into actual products, as the market forces deem most of them to be unacceptable for one reason or another. It's possible the company never actually made any of these in any significant quantity.
And, does anyone else find it amusing that a skeptic has done more to prove his case than he has? Perhaps my willingness to actually point out evidence that supports him will show we're not just mindless sheeple......Naw, who am I kidding?
