Well, something just happened that has caused me to reconsider developing my idea further.
I was just at a company meeting, where we were discussing equipment used to apply agricultural chemicals. As with most such meetings, we spent a good portion discussing spray nozzle tips, which spray chemicals onto the crops. There are hundreds of different nozzle designs for use in different applications, because of differences in speed, spacing, rate used, etc. Selecting the wrong nozzle can (and does many times every year) cause a poor job, or a drift complaint, both of which easily become multi thousand dollar problems. Field conditions vary so widely, that it is pretty much impossible to use one nozzle that will do a good job for everything.
A year and a half ago, after sitting through another such meeting where we spent a whole afternoon on this subject, I wondered why someone didn't just make a nozzle that would self adjust to the pressure and rate. ??? So within an hour of thought, I worked up a simple design that used a spring loaded piston to adjust to pressure variances. I drew it up on the back of a notepad, and shared this idea that night with a coworker at our hotel. He said, "Well, ya aught to patent it before someone else does", or something like that.
I just found out someone else has developed such a nozzle based on my same idea. The man speaking basically said they are still refining the design, but it will make all these hundreds of current spray nozzle designs obsolete, and will become the industry standard within the next several years.
I also have a simple idea for improving certain modern muzzle loading rifles. One of these days, I bet I'll see someone else's name on it as well.
I think even if my pivot screw idea never takes off, I'd at least like to say I did it first. But, as with most ideas, they're 10% inspiration, and 90% perspiration. I better get to work.
