try to appreciate...

Self work, a hard stuff...

BTW, sorry, a PS on my previous msg:
- while working on power semiconductors market, I got a really GREAT, absolutely definitive and still original design for the very best Heat-Sink...

[murilo]

This is also a huge work!
Maravilha!

If you are NOT my friend, please, be kind to never read this matter, ok?

( I stopped with smoking in 20th/oct/1988, at 4:20PM... 26 years without smoking BUT still a heavy non-operational smoker... B[[[
I'll try this, even if I still remember that at 11PM, every night, I have had troubles with the depressive tobacco effects! )B

Kind of like strolling through Henry Ford Museum in Dearborn Michigan.

This is VERY interesting, with old age dementia and other neuromuscular disease ailments what they are. VERY interesting, indeed. I'll be following this in the future.

I wonder if they could isolate the specific nicotine components that provide the effect?

[murilo]

TGM,
yep... pure nicotine from Glaxo abs.

One can find in market those patch dedicated and indicated to people who want stop smoking and will 'find' some nicotine replacement.

Down here they are found in 3 concentrations. Bf~

Art, could you post a diagram of how you implemented this arrangement vertically?

It is interesting to see peoples different interpretations as to the operation, and the way in which people imagine an advantage is to be had.

My interpretation of the single sided John device being that he uses a motor which vertically lifts the weight through horizontal displacement of the lever end. The mass then travels down as if on a ramp to rotate the bottom gearbox/generator. Although I do not see the advantage input vs output, I fail to see how this movement can be achieved with a balanced mass.

Hi Tarsier ,

Sorry for the delay in replying , I had a catastrophic computer crash three weeks ago which propelled me back to cave man living and I didn't get to see your post until yesterday . Hadn't realised how dependent I have been getting to the digital master box until I lost it all.
I have a new computer system now which I have taken a solemn oath to that I will religiously backup up on a regular basis on an independant system that will allow me to recover quickly if it ever happens again . You live and learn , and learn and learn .


In regards to the "John Device" I think your explaination of the single sided design is what occurs at slow speeds , ie gravity supplies the force which torques the shaft for the first approx 180 degrees , but then of course the weight must be raised vertically during the rest of the 360 degrees of rotation so it is reset for the next cycle . The force that you have to input to raise the weight again is what torques the shaft . As you intimate - there is no difference between input and output in terms of energy . The single sided system is really no different than swinging a weight on a string in a circle . The input energy is converted to rotational energy by virtue of the force of the inertia of the weight (as centripital/centrifugal force ).


In a balanced system ,as you mention , this can't and doesn't work . However the system as drawn in GV-1b isn't balanced in three dimensions ,ie the weights are 'balanced in the x/y plane but not in the z plane . The two weights are offset on the rotor axle . This allows an input of energy to the rotor by means of the forces of precession . The force from the input energy has to be applied to the opposite sides of the shaft offset by 180 degrees to each other . In the GV-1b drawing he doesn't offset the shaft at the driver/generator end , but it doesn't make much difference since it is the absolute "excentricity" of the shaft to the centre of rotation of the shaft that is important and this can be varied by the 'excentricity' of the other shaft bearing and the distance of the centre of gravity of the rotating mass from it.


In my experiments with a vertical version of this system I found that the positioning of the offset weights on the wheel in relation to the direction of the position of the excentric displacement of the shaft is critical [ ie the weights say at the 12 and 6 o clock positions verses the shaft excentricity direction in the 3 and 9 o clock direction ]

It's about 14 years ago since I fiddled with this type of system ,and my possibly delusional conclusions were that the system gives almost unity ( input = output ) but nothing extra .

However , in retrospect I have identified one aspect of it that I didn't think of testing which could lead somewhere and that will be on the table if my current build doesn't give me what I know its going to : )

Hope the attached diagrams might make it a bit clearer [ if I can figure out in this new computer system how to scan and attach it : ) ]

Oops sorry about the gigantic size of the drawing in that j-peg !

Any ideas how to shrink it ?

I have a process I use in the free program "IrfanView"

Resize/Resample
Right side - select 640 button

Save(Original Folder)
Add a letter like "S" for small to the filename

Voila! Much smaller but legible on any website. I use it to post pics of my car on my car website.

Thanks TGM , I'll give that a go after I get a bit more I experience with my new computer setup . A bit nervous about fiddling with drivers just now and the Irfan View site seems to want to change 15 of them !

Cheers Art

TGM,

So where is your car web site, you do not have it listed in your profile.

I am a 1950's hot-rod and custom build hangover, I like autos and pickups chopped shaved, leaded and lowered.

As soon as spring arrives, I am starting a project of refurbishing and customizing a 1992 diesel 3/4 ton Dodge Ram. Removing the pickup bed, to be replaced with a wider low as it can go flat bed with full skirted sides and teardrop fender wells. Front end will receive new custom grill retaining the seal beam headlights that are of real glass. Frenched in not unlike the 55 chevy.

Also intend to add a custom windshield sun-visor molded into the roof with ICC running lights.

Add a highlighted stripe on the sides, full length of the cab and bed, this gives the illusion of it being longer and lower. Fender skirts are also being considered.

This will become my "Tote Goat" for pulling a single drop RV 5th wheel trailer which the front step (frame) is lowered to just clear the lowered wheel wells
