CMF provides a solid mass at any depth ?

You do not know the ways of dealing with the Patent Office to ask for a description.

Does it work on the same principle as the Viper - CMF oxygen mixed with a variable amount of diluent SCR style?

CMR (Constant Mass Ratio) O2 and inert directly proportional to the hydrostatic pressure, all my solutions count ventilation.

That's not any proof it works. I could get a patent on cold fusion, it doesn't mean I have a working reactor.

You did not answer my two questions, regarding the application and liquid dosage scaling, in your solution.

Know or not, do not find anywhere any link to your patent.
If it was granted the description or at least short description would be available.

Description You can read after writing a registered letter to the Patent Office, then in the early stages is access to a document if the author agrees.
The most interesting is the first version, the final will be truncated on the theory of this class of SCR SMS.
It is in the process of decision-making one decision became final, then this will be the final for this application. It will take a few months before the description is rewritten and published. I guess I do not want published a possibility also exists.

The first steps that can keep CMF always supercritical flows are known (Air Liquide) and laminar resistance in the dosing system (Cobham).

Begging the question: "Why Bother"?

(1): SCC in all of it's versions is an evolutionary dead end. Nobody seriously considers them for the huge majority of diving. Even the last of the holdouts, GUE et-al, is migrating towards eCCR's.

(2): Bleed orifice 02 flow is available with small orifices and high IP's to depths nearing human limits already. If you want to dive to 200 meters, you are smart enough to either use a good eCCR and a manual add valve if things go wrong with the controller or are smart enough to know that you don't really need to add 02 for your bottom time, or (most likely) you carry two 02 supplies anyhow.


So <yawn> to all of the above ways of making a silk purse out of a sows ear.

1. The diving direction military is quite durable. This year, at a meeting of NATO in Turkey was presented IS-MIX Interspiro, Aqua Lung Military also has a SCR, Draeger also, Russians Respirator also, some with chemically acumulated oxygen.
A few years ago I heard that it is a closed course.
Was founded SCR with chemically acumulated oxygen (constant ppO2). This solution is widely opened the door to talks in Nice Aqua Lung Military. In addition, they created modification to constant ppO2 SCR CVR.
It can be used to GEM constant ppO2. When Mike Young to understand what's going on, in the patent, which was.
This is not a closed direction.

2 To SMS SCR constant ppO2, I needed to know the basic family models ventilation: CMF, CVR and CMR. I realize this right.
Exactly the point to add valves always at the same time, give out the same dose of oxygen, at any depth.
The CMR solution is very simple and I got it patented.
The CMF is a little more complicated design of this to be achieved.

Note the two sources of O2, interesting thank you.

Perceptive for one of them 'mericans... ;)
 
Some sort of pressure transducer on the CMF valve? So the deeper you go, the less gas is delivered. I could be way off, just throwing an idea out there.
 
So when you press purge what controls ratio of gasses?

Relation of psia O2 vs psig of N2... but how this relates to what you inhale I am not sure, I think it would come down to tuning and servicing of first stages, obviously restrictions of pipework being very closely controlled.

I think it could be controlled, but it would be very empirical. You calibrate and hope nothing changes. One first stage gets one grain of salt inside and goes a bit slow... change of PP02. Not absolute and not scientific.

Given the comment here, I don't think that's the intent??

Blanket patents for the sake of them seems to be the fashion, get the lot then send the lawyers out to do the hard work, this stuff in sheds is for fools it seems. I still suspect the only reason we had so many photoshoped iCCRs in the wild is for an attempt at prior art on the CO2 exhale sensor.

Perhaps a JV for our friend with Mr D might produce a better love child?

Military procurement systems tend to be.. peculiar. And I'm not talking about operational requirements. Extremely long use time, extremely long buying processes, sometimes managed by multiple individuals as dictated by promotions, and not necessarily domain experts, intensely political...

Military radios are technologically at the level of your 90s mobile, and telcos are not exactly fast-moving.

Just because the military's buying it (never mind using it) does not mean it's any good (although obviously some of the kit is the state of the art).

It does mean you still may have a market, tho.

Just thought I'd point this out...

Cheers,

I know the theory behind MCCR, and I've also been diving one for a while.

I dive a hybrid CCR. It has a CMF (fixed IP first stage, plus orifice in the hose) and a solenoid from a separate cylinder with a compensated first stage.

I'm not a guru, but I do dive in the Channel a lot in the 70m range with the odd dip below 80m. I've not been deeper than 100m outside training. My IP is set to 10.5 bar.

The CMF flow has to be set low (to your deco O2 consumption) and so any mCCR diver is going to have to add a bit of O2 for the bottom phase of the dive. This is true at 30m as at 90m.

I might have to add a bit of extra O2 during the deeper dives, but I can't say I really notice. Depth changes and swimming hard have a bigger effect.

The only thing I really worry about is exceeding the IP of the reg, in which case there's a danger of loop gases (which will be humid) being forced back through the orifice and into the reg. I've had a little bit of corrosion in my orifice (fnar fnar) but an ultrasonic bath sorts it out.

So for me, a fixed IP and an orifice is great, but I don't do 130m dives like some. If I did I'd get a stronger spring and a smaller orifice and up the IP to 18 bar or so.

I've lost count of the great ideas that have passed our portcullis that just won't work. Life turns out very different when that idea must work at 100 or when dedicating a guildermeister to it. In this instance, I don't get a warm feeling with you. It might be the one liner answers or obfuscation.

To patent something, the solution must be new.
There can be anywhere similar solution previously reported in any Patent Office in the World. Also in any of published sources. Even in our forum.
Wherever previously released information legible to experts, the solution can not be patented. It was previously revealed.

An exception can sign the NDA, the company does not want to sign such a contract.

They prefer to give solutions without any protection from the author!
So lose the good ideas.

Respectable companies only talk about patented solutions.

My solution works.
You do not have adequate capacity. Nov We do not produce complete CCR and SCR advanced.
