I tried to send this to M.G. Devour at [email protected] but got an error message saying that this address was not deliverable (error 550 - Domain has no MX or ANAME record) so I will send this to the list. ======================= I'm afraid I began the "Trem-bashing" I certainly did not mean to start any sort of personal attack. Trem shared his research findings that current regulation may well be essential for proper CS production, which makes good sense, pending some actual lab measurements. But then he added: >>Yes, current limiting does work and quite well. We have a current regulator >>in our generators which hold the current at 1 milliampere throughout the >>whole operating time. The end product is always the same: uniform small >>particle size and little or no fallout. >>I would post the circuit for the members but after all we are in business to >>sell generators, not to give our proprietary circuit away. =================== I responded --- >>What is proprietary about a current regulator? >>This has been a standard electronic circuit for over 30 years (older than >>that in the tube version). >>National Semiconductor came out with an integrated circuit version in the >>70's, I believe, the LM334 -- the data sheet is available at >>http://www.national.com/ds/LM/LM134.pdf (The LM334 is the cheap commercial >>version of the LM134). It costs about a dollar. >>It has 3 terminals V+ V- and R. It's been years since I actually used one, >>but as I read the data sheet, the V+ goes to the Plus terminal of the >>battery, the V- terminal will go to the silver electrode and the other >>electrode goes to the Minus terminal of the battery. The current setting >>resistor is connected between V+ and R -- . It looks like a 68 ohm resistor >>will set the current to a steady 1 milliamp with a battery range of about 3 >>volts to 40 volts. >>Or am I missing something? I tried to keep this a level-headed response, but this was apparently seen otherwise. I have designed circuits of this type for 30 years, and as far as I know, current regulators are standard text book circuits. I just wanted to point this out and I asked to be corrected if there really was anything unique. The next response was >What I said was, I wasn't interested in showing OUR circuit, which IS >proprietary. Of course there are many current regulator designs out there. >Some are quite complicated; some aren't. Ours just works quite well at >holding low current levels with very little temperature drift and undue >complexity. We use discrete components; i.e. transistors, diodes, >resistors. Anyone is free to use whatever they think they can assemble. We >just design and assemble colloid generators for others and charge them for >our expertise and labor and make a profit at the same time. No problem with >that as far as I can see. >Good luck on your home electronic project. ======================== I meant to respond privately but inadvertantly sent this to the list: What you implied was that you are doing something that nobody else can. That the non-technical person better buy from the expert. Your systems seem fine and reasonably priced. But why pretend that you have a big secret. > What I said was, I wasn't interested in showing OUR circuit, which IS > proprietary.

This implies that discrete components have some superiority over I.C.s. Sorry but in this application it ain't so. I would agree for an audio application where there many complex factors involved, but we are talking simple direct current here. > Good luck on your home electronic project. This is a rather patronizing statement. The current regulator component is built by a leading semiconductor company and has been used in thousands of professional products for decades. We are talking about a power source, a current regulator, and wires. Not exactly complex and it does NOT require expertise, just enough skill to know which end of a soldering iron gets hot. =============== That's about it. What came through to me was an effort to make a simple technique seem somehow mysterious. I am not a tinkerer and would gladly purchase a tested professional instrument rather than try to develop a design myself. I know how time-consuming this process is, even for a relatively simple circuit. But this is a VERY simple circuit, well within reach of anyone with hobbyist level skills. The spirit of this field has been to share the research and charge for the service of assembling and testing a device. As soon as someone claims an essential secret technique this spirit is damaged.
