you have to apreceate that many of the effects you have listed go back to the 1800s.The broom suspension could be credited to Jean Eugene Robert Houdin.
The sword suspension, do you mean the one with 3 swords, 2 of which are removed, thus one at the nape of the neck supports the weight? or do you mean the impaler Ilusion?.
If it's the impaler, then the first variation was created by Les Levant, altough a more practical version is favoured today.
The disembodied princess, is the creation of P.T Selbit, who also created the first saw through a woman, as well as many other Ilusions.
I believe tha you will find that the hindu basket is litraly as old as time it's self. As is the Coconut, althouh you will find variations of this in Fabian's excelent book on Louis s Histead, Published in the 1040s.
The electric saw through, as described in your post, was, as far as i know the Invention of Jack Hughes.
It was in turn a variation of the Harbin bow saw through, and i am guessing that, since Jack and Robbert harbing developed many ideas together, Harbin had some input on it as well.
I hope that these answers are of some use...
