Thanks. My poorly composed original post should had beed focused in the area of interest, the copper cladding of zinc as blank rounds metal source. The process of minting is explained in several sites. Do you know details about that process ? Edited, added: Found something at many sites, by searching with proper terminology ----> http://smt-holland.com/#/explosive_cladding

Hi. Over twenty years ago, I was told that the cent coins (pennies) were made from zinc sheets with bonded copper foils above and under by a very high pressure explosive method, and then the blank rounds cut from the resulting layered sheet, to be later stamped at a mint. Is that true ?

Hi. Do bimetallic junctions with no electrolyte at all, and both at same temperature (no thermoelectrics related) produce a minute amount of voltage ? As in explosive bonding, electroplating, sputtering or other processes, where two dissimilar metals are intimately joined.

In spanish the 'voy a tener', 'van a ser' , and zillion more are products of bad translation from English mostly originated in translated news, sadly from ignorant translators that have deeply contaminated spanish to the point of being widely used, rarely being noticed even by people self-convinced they speak properly; to the point of wrong language being disseminated. Correct spanish for the above is tendré; serán. Hasta el irrisorio 'vamos a venir' ¿O vas o vienes ? Ninguno de ellos. The correct is 'vendremos'. Fourth grade of elementary school. And very few people notices. ----> You were not aware of such by replying Spanish being an example. Wrong. Widely misusing a language does not make it correct.

Hello. Always had this doubt about the expression being perfect English. - He is going to switch this on. - He will switch this on. (He is going nowhere to switch this on. The switch is right here) Understandable in this case: - We are going to eat at the restaurant tomorrow. - We will eat at the restaurant tomorrow. (Because the restaurant is not here, we have to go there) - There is going to be elections next week. - There will be elections next week. ( I believe 'going to' is not correct, or better said, 'not perfect') Yes, both ways are commonly used, perhaps the 'going to' more often. Even when there is no actual going anywhere/moving/traveling to express future. The point is if the 'going to' is an accepted aberration or degenaration from an antique/pure/perfect 'will' expression. English has no verb conjugation as other languages, or very limited. But the 'going to' smells like widely misused or from vernacular. Educate me please ?

Hi all. Along my life, I have seen some variety of manufacturing machinery. Never had the luck to see how mechanical wristwatch parts are made. Not even pictures. And they have been built since at least 1700. How were the parts made then ? The tooling is a mystery to me. And beyond this, who makes and how is the machinery to make wristwatch parts ? The entire factory fits in a suitcase, right ? There is a hidden universe there. What do you know about ?

Hi all. Name the favorite toys, the ones that stayed in your retina, the ones you had, the ones your rich friend had and you always drooled for... Starting... - Pedal firetruck... well, I was like six. Unforgettable. Zero plastic. - A building blocks set. Not Lego, did not exist then ! - 9 transistor radio. Had shortwave band ! Fixed it when was ~15 - Lionel electric train given used from rich people, and still in the family. Real all metal. - A free-flight diesel engined model airplane balsa kit, given to me by someone out of the family because was too complex to put together. I did, and crashed first launch as I was reluctant to give full trottle. - An electric boat, about 30cm, made with real wood, 'D' batteries and perfect metal fittings, zero plastic; a perfection masterpiece that should had cost a brutal amount to my poor dad salary. But he saw me drooling for it on a store window. - A firetruck, with a pressurizable reservoir, hose and valves. Tadpoles grew to frogs in it, as I forgot them for a week+. Ah... metal cast, zero plastic. - A CocaCola metal delivery truck with dozens of individual 1cm bottles, and cases and shelves for them. - A Schuco Mercedes benz, windup, with working gear shifting and steering. All cast metal too. - A .177 caliber air pistol. Nobody else had or seen one. - A galena radio. This kicked me into electronics engineering. Envy from friends: - Real chemistry set, when you could really make experiments without today's legalese intrusion, - A vacuum-forming set. Made objects from plastic sheets... still want one. - Bicycle So sad to see kids today hooked to the f'kn Nintendos and other screen crap. Your turn...

Thanks ! Was not that far. In English, simply, gentilic it is. And a bonus from your responses, gentilic = demonym <--- That, I did not know.

Gentilice is french. Gentilicio is spanish. Volksbezeichnung in german. Gentilico in portuguese. -AFAIK- Is there such word, or perfect translation/meaning in proper English? I thought having seen such word somewhere within English text, but may be confounding the spelling to look for it. I do not want to believe in on-line dictionaries for this one.

Thanks, dear very respected gentlemen. Most modern TV tuners use mosfets/fets devices at front end. Being high impedance gate devices, I believe they do not respond properly to circuits ahead of them to force near matching to 75 ohm antennas, wasting signal capture. Am just trying to confirm that is a cause for marginal reception/pixelation in ATSC. And attempt overcoming the limitation. So far, using a 280 ohm antenna on a TV instead of its original configuration, got rid of a plague of marginal/multipath/loss reception problems. Suspect the industry would do much better breaking ties with 75 ohm pseudo standards that correspond to other eras and not to modern tuner design. But instruments are based fixed on mostly 50 ohm standards and their response to other impedances equipment is simply wrong. And manufacturing/design uses such 50 ohm intruments. There are no others. I believe modern tuners are forced to near match 75 ohm because nobody builds antennas in other impedances that could outperform the currently available ones. Will, at some point, modify a few tuners to route the antenna signal to the gate without much loading and evaluate results. All within my limited skills as you have noticed. Now I changed the configuration of my test equipment for evaluation. The analyzer in duplex mode, 0 MHz shift, instead of tracking generator. Means both RF generation and reception analysis simoultaneously working. Switchin-in the tuner in circuit is revealing sharp deep valleys loading the generator at many spots in the span. Well, there are compartmentalized tuning sections for each band, some of that is justifiable. Yes, I have a Celwave circulator model CC460-S sort of directional coupler, but of limited frequency span. Spanking welcome.

Thanks, gentlemen. Knowledge, knowledge... the key for everything. Having the test equipment shown is not the whole story.

Thanks. I do have a antenna analyzer up to 170 MHz. Even if was the range I want, it is not the case. Reworded ----> Am looking to measure the impedance a television tuner antenna input presents to over-the-air signals. Not a tv antenna impedance. And if you think it is 75 ohms; well, cannot be at more than a few points in the range. Unable to find credible plotted data on the net. TV tuner data sheets do not reveal the truth. A typical antenna (not tuner !) plot looks like : ----> http://s588.photobucket.com/user/Innernet/media/Screenshot-TVantennapdf.png.html?sort=6&o=40

Hi. This could be on some other forum, but, here it goes. If any electronics guru is around, I would like to know how to measure the (antenna) input impedance of a television. From ~50MHz to ~800MHz. in whatever steps. 1 MHz, 5MHz, 10 MHz... Would you have the proper instrument ? What is it ?

Hi. Would partial vacuum desalination or distilling produce also cooling as for 'air conditioning' ? The vessel containing the liquid being distilled will get cold, right ?

They are not, never been cheaper than now (scroll down) ----> http://sunelec.com/ And these are prices to public, not manufacturer's ! Depends on your energy costs. Solar panels don't work when the clouds are overcast... Wrong : they just yield less. Did you expect other ?----> http://www.leisurebatteriesireland.com/store/image/data/AKT/AKT20%20web%20output%20graphs.jpg ...sunny areas of roofs are too small to accommodate all electrical needs That is a roofing fault, not a solar panel fault, and you thinking that is the only place they can be mounted. Battery storage is useless because there is no place to put the DC to AC inverters. That is room fault, not a solar panel fault. And inverters can be very small ----> http://www.solarelectricsupply.com/solar-inverter/magnum Circuit breaker panels are not accessible to parallel wire hookups, To parallel what ? You have to disconnect the main breaker to feed power from your inverter into an existing breaker panel, or can kill someone working on power company lines; ...and buying a new one is a huge extra expense. No, it is not huge. A breaker panel is less expensive than solar panels or inverters or batteries. If there is no basement or a place to install the inverters, a small outside building will be needed to house them. An inverter can be smaller than you think. Did you expect it to be the size of your smart phone ? And one suffice.----> http://www.solarelectricsupply.com/solar-inverter/magnum

Among all human organs, which are less prone to illnesses, failure, cancers; found in better condition than others at old age death, or rarely give/harbor health problems ? To what would you attribute such endurance ?

Could natural particles collision with genetic tissues be a casual causal of genetic mutations or evolution ? Like the ones observed in a cloud chamber, or others that escape observation, hitting by chance a key/sensitive location of a gene? Would deep undersea creatures have less chance to evolve if this is factual ?

¿? That is the opposite from your original post. And their business is providing education, not housing. What I did is bought a home were I was able to afford, rented out, and with that income paid rent nearby my workplace (or college for you).

There is flying cars, but they are called Piper, Cessna... and likely you can not afford them. Most of the others exist too. But not in your budget. The prediction was not far from reality, what differs is the speculators never revealed you would not have them. Having the mean$, you can have those toys. If Cessnas were $5000, the skies would be the most horrible mess you can imagine, likely dying on first flight. The key is in your own paragraph above. Past speculations on science fiction.

You have shifted college costs on the original post to housing costs. That is why I moved from Silicon Valley to a national forest in KY. Hords of just arrived orientals with suitcases filled with cash paying more than asking price for California real estate the locals cannot afford. I wonder the legality of the funds origin. And sellers singing on their way to the bank together with the real estate agent and laughing at the idiot buyer who paid ten times its reasonable value. (fact) Living styles in USA have changed since the fifties; people moving to affordable rural suburbs and commuting loooong distances. Nothing new.

Colleges/universities are not put together to teach youth. Are businesses. The more they wring students and parents wallets, the better for them. And they start by fishing high school graduates even paying flights and accomodations to potential 'victims' to familiarize with their college offerings and status, promising huge discounts on overinflated tuition as another hook. -Smile- , tomorrow will be worse.
