Win Hill: Inverse Marx Generator ??

fairly old looking (~1980s) 4700uF 50V electrolytic. It looked to be made of moist kraft paper (i.e., the brown untreated stuff they make paper bags out of, but the thickness and strength of tissue paper) and two sheets of ~5mil aluminum (one grayer than the other, probably because it was the anode).

etc., but if they use generally the same thickness for all voltages, you'll see essentially constant CV over a series.

I think that aluminum caps pay a big volumetric penalty for the carrier foil thickness as compared to the aluminum oxide, the real dielectric. So a thicker AlO2 layer shifts the tradeoff towards more dielectric, less aluminum overhead.

For some reason, for a given C, higher voltage caps have lower ESR. I guess they just have more surface area.

Sorry, retard boy, but I have had this one for years.

Too bad that you are such a green, Usenet ditz.

Those were most commonly referred to as "stripper clips", and the dipshit already mentioned them to try to make his position, but it failed, as did he.

I thought the "police special" rounds were about right. I guess the police did too, since they were called "police specials."

Firing the magnums at the range, I'd have to stand sideways and use both hands. One shot, and guys would come running up saying "WHAT was that?"

Time-variant caps are unusual in electronics. Varicaps, of course, but we don't often care about their energy considerations.

Any voltage-variable capacitor, like a varicap or a high-K ceramic cap, can be used parametrically to get power gain. Both are also used to make shock lines, nonlinear transmission lines that have output risetimes faster than their inputs. Fun stuff.

I guess the reason we don't have any true three-terminal variable capacitors (like, say, a gate that controls the capacitance between two other terminals) is that CV would be conserved so 0.5*C*V^2 would have to change, so where would the energy come from?

No. A stripper clip is stripped off the ammo as you push it down into the magazine, then discarded, hence stripper. Used mainly on bolt action rifles, like the Mauser Gew98, and Lee-Enfield.

An en-bloc clip stays on the ammo, in the weapon, when it's loaded, and gets ejected when the last round is fired, leaving the action open, as in the gas-operated M1.

The link I quoted explains the difference.

Not the same thing. See the link I quoted above for an explanation of the difference between stripper, and en-bloc clips.

That term was coined by Colt long before cops decided on them.

It is the original .38 Long Colt revolver round with a bit more juice and a few variations on the projectile as well. It is actually .357 caliber.

It has been around since 1899 and economics had more to do with its ongoing selection than any other factor.

Good way to get killed.

Always count your shots and stop short of the last one, and reload

*without* the telltale fling-and-ring.

Well, he insists that he right, even when he's *clearly* wrong. Always.

You're not paying attention. You may see that while he's got his nose up your ass, but DimBulb carries on as ever in other threads.

Because he won't accept the corrections and is otherwise useless. Pay attention.

If they are a subset of "machine gun", then he's right; (some) machine guns have clips/magazines. If you define a "machine gun" as one where an outside power source drives the mechanism, then I can't think of any that aren't belt-fed. OTOH, gas-driven automatics generally are magazine fed.

I have a stainless .357Mag, S&W 868 (and it's twin, chambered in .22, the

617). It's pretty but not as nice as my Beretta 92FS "Inox". ;-)

It does take a little practice but it's not *that* bad. The flash-bang is impressive due to the leakage around the cylinder but the kick is quite manageable.

(You forgot "cylinder" ;-)

Sure it matters, at least to anyone interested in how these things work.

Many didn't believe they had enough "stopping power", so used .357s (same caliber, more power). Same deal with the 9mm vs. .45. The 9mm is very similar to the .38 special.

Not much of a range. .357s, .45s, and .44Mags are all popular at the ranges I've been to. I like the .357 because it'll take the *much* cheaper .38 ammo for plinking, yet makes a big boom for fun. ;-)

Define "machine gun". What true "machine gun" uses a magazine?

Well it's more than just molecules. It could be electrons, ions, atoms, photons, and lots of other 'things'. The magnetic moments in a system can have a 'temperature'. I'm sure you've heard of magnetic cooling.
