Re: re: United States Patent Application 20080011552

Thought a working model was required prior to a Patent being applied for in the States. G'day ectropy and all, This is a moot point. The USPTO can, if it so wishes, demand a working model. In practice they hardly ever do. There are a myriad of unworkable and outright idiotic patents given out all t...

Steve
There is a crack available that makes the programme 100% functional.
If you want details mail me hans@keelytech.com

re: Interesting Design

You are correct, WM2D can be a good guide if the models are simple but the ultimate test is a prototype.

There are a lot of bugs in WM2D. I have a whole collection of perpetual motion machines that run in WM2D. Here is one of them put together by Stefan Hartmann.

re: Interesting Design

I'm sorry to say, but your simulation is invalid. I know now what you have done. When you first started the programme you got an error message something like object x is overlapping object b do you wish to continue? Evidently you pressed yes and this is when the whole thing went haywire. WM2D cannot...

re: Interesting Design

but it isn't failing, it's running more vigorously in the simulation

re: Interesting Design

G'day Dave,

Welcome to this forum. I have been playing a little with your design and I am beginning to harbour the suspicion that you have struck yet another bug in WM2D

Have a look at this.

re: Simple CrossBar Oscillator

If you have a look at my other simulation you can see why your arrangement behaves like this. In this type of arrangement the centre of gravity shifts along the y-axis mainly. In a pure system there is no movement along the x-axis at all. In your arrangement there is some but it is erratic, taking o...

It is working now. Just tested it.

re: Simple CrossBar Oscillator

Sorry Ruggero,

The file must have become corrupt during transfer. The avi on my computer works fine but when I downloaded I had a problem. Will try to upload it again.

re: Simple CrossBar Oscillator

G'day all, Here is an interesting experiment. In the simulation there is a sliding weight with a pendulum attached. The fascinating thing here is the movement of the combined Centre of Gravity, which is exclusively along the y axis, there is no movement along the x axis at all. It would appear here ...

re: Simple CrossBar Oscillator

G'day all,

In my view Bessler chose the use of the word Ding here with care. Here the word is used in my view in the sense of object. By being non-specific he implies that no matter what the shape, weight or material of the object, it is the ability to move it that counts.

re: Simple CrossBar Oscillator

G'day Ruggero, Here is your simulation in avi form. The system does not work, the movement of the balance beam is erratic and random. The reason is that when the pendulum swings to the right the sliding fulcrum moves to the left moving the centre of gravity or the moving parts more or less in the sa...

re: Simple CrossBar Oscillator

G'day all, Just as a general comment. Reading the passage as a poem one could easily get the impression he is talking here about a mechanism that is released by a one pound weight dropping a short distance onto something like a catch on a spring, liberating the spring and propelling a four pound wei...

Sorry guys but I do not quite agree with the translation, though it makes little difference as to meaning. Der wird ein grosser Künstler heissen/ Wer ein schwer Ding leicht hoch kan schmeissen/ Und wenn ein Pfund ein Viertel fällt/ Es vier Pfund hoch vier Viertel schnellt. &c. schmeissen I wou...

re: Simple CrossBar Oscillator

Yes Ruggero,

I will make a simulation and an AVI so you can see it. Give me a couple of days.
