When I used mousetraps it was easy to find the dead mice. But when they crawl into the wall to die after being poisened, it's not so easy. I could always locate the area, but I didn't cut through the wall. So I quit using poisen.
My guess is that it did, until it was thouroughly dessicated by the current passing through it. We had just rented the house, and the cooked rat in the range came with it. Who can account for some people not investigating smells. I have always tried to locate the source of any unusual odors, whether foul or pleasant. In fact, I have often located the failed component on circuit boards by the smell, usually confirmed by either discoloration or deformity caused by the overheating when it failed.
I would think the rat would stink and alert the occupants that something was amiss behind the stove. I once used rodent poisen to get rid of mice. They would eat the poisen, then crawl into the walls to die. We could smell them for a week, but we couldn't get to them.
When I was a young teen, we moved into a rented house, where the electric range did not work properly. On pulling the range out from the wall, we found a rat that had been electrocuted and cooked across the terminals where the 240 VAC feed from the wall socket connected inside the range.
"A good example of what happens with the latter (self-reset) type can be found in most lamp ballasts: we've all seen fluorescent and other discharge-type lamps that SLOOOOOOOOOWLY cycle on and off all by themselves as the ballast and/or lamp gets old and triggers the device during "normal" operation. It's especially annoying in vapor-discharge (mercury or sodium) street lights (even more so if it's the one right beside you bedroom window!). "
Actually in this case it isn't a reseting cutout but a fundamental property of the gas discharge lamp. As the lamp ages the voltage required to maintain the arc discharge rises, eventually (about 20k-25k hours for HPS lamps, about 3/4 that for mercury & metal halide) reaching a level higher than the max running voltage available from the ballast and the arc extinguishes. The discharge tube then cools to a point that the arc can be restruck by the ballest whereupon the lamp's arc tube reheats and the cycle repears. The solution is to relamp the fixture.
I thought that was a huge disappointment when it was cancelled, Ratski. So instead of Texas, Europe gets all the glory, all of the jobs, and all of the resulting technology.
At least your dishes should be super clean as they were being sand blasted as well as washed. The each little chip probably became part of the blasting process. I wonder just how far it would have gone before blowing a hole through the door. Just a thought.
The Superconducting Super Collider (SSC) (also nicknamed the Desertron[1]) was a particle accelerator complex under construction in the vicinity of Waxahachie, Texas that was set to be world's largest and most energetic, surpassing the current record held by the Large Hadron Collider. Its planned ring circumference was 87.1 kilometres (54.1 mi) with an energy of 20 TeV per proton. The project's director was Roy Schwitters, a physicist at the University of Texas at Austin and Harvard University. Dr. Louis Ianniello served as Associate Director.[2] The project was cancelled in 1993 due to budget problems.[3]
Waxahatchie is about 30 miles due south of Dallas, and certainly would have both fire ants and sandy/shifty soil structure. I suspect part of the "budget problems" was failure to see how expensive solving foundation problems would be! Typical government boondoggle IMHO. Thought so at the time, still do!
I'm afraid neither I nor Google can remember or find anything about that! Try Snopes; sounds like an (non)urban legend! There may have been other reasons. Most of Texas has relatively unstable soil formations (that's why few newer houses have basements, because the codes now require floating slab foundations).
Most transformers of this type need to have such a device to get their UL/CSA approvals. The unfortunate part about this particular one was the manufacturer's choice to use one embedded deep within the windings (presumably at the potential hottest spot), and to use a non-self-resetting one. This unit was potted, so I wasn't about to try to rewind it! A good example of what happens with the latter (self-reset) type can be found in most lamp ballasts: we've all seen fluorescent and other discharge-type lamps that SLOOOOOOOOOWLY cycle on and off all by themselves as the ballast and/or lamp gets old and triggers the device during "normal" operation. It's especially annoying in vapor-discharge (mercury or sodium) street lights (even more so if it's the one right beside you bedroom window!). However, I suppose that's better (from a safety standpoint) than a street light that's out and stays that way!
For 3D printing to make the jump from rapid prototyping to manufacturing, engineers will need to find easier ways to move products from their CAD screens to their printers.
Gigabit and PoE are two networking technologies moving ahead in tandem as industrial users power remote Ethernet devices such as IP security cameras at 1,000 Mbps over existing CAT5 cable.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
