The smoke alarm works on the principle that infrared scatters in the  smoke to probe the smoke which is generated by the incomplete combustion at the initial stage of the fire. It consists of photoelectric system, signal processing identification circuit and alarm circuit. The infrared scatters on the surface of the smoke when the smoke enters the darkroom of the detector, then the photoelectric diode receives the scattered light and generates the photoelectric signal current. The photoelectric signal generates the alarm signal after being processed by the identification circuit, accordingly the purpose of alarming is achieved. mini

Q:What to do about my house's humidity level?
Since most of your shirts are girly, I wouldn't mess with them in case you want to go back to that style. For the same reason, I wouldn't rip your jeans. What you can do to try out the rocker look is to take a plain black knit top and cut some diagonal slits in it and then pin a couple of safety pins on one of the cuts like you're trying to hold the opening closed and not succeeding. Ha!! The other thing you can do is to wear a heavy black belt on your hips instead of at the waist and on top of a long fitted top. A black cuff bracelet with studs makes an instant rocker look and you can attach a plain open link silver chain necklace to the waist of your jeans. Attach one end and then about a foot away, attach the other end so it hangs down in a loop over one hip. This would be a substitute for the heavy belt option. You could also take one of your oldest plain hoodies and dye it black if you can't afford a new one or trade one of your hoodies with a friend who has a black one. Good luck!! : P
Q:overheating colored glass bowl for resin?
The man may have had to give up some land for what is called public domain. Call City Hall, find out if this is the case. If the authorities took the land for the better of the public, or whatever, then he does not actually own , or have any right to it than anybody else. He might just be harassing, and know it. Find out, officially, who owns the road. Is there a county road sign there? It should be marked, but I think you want to use the road, so find out, for sure, who owns it.
Q:All Important Question Of The Day 342?
because steam contains heat setting of the sensor
Q:Please help me solve this problem?
Cables break too easily and chains provide superior traction..
Q:Why do plastic bottles contract and get deformed when hot water is poured into them?
I would believe its because like with a life jacket it wont let you go down far and you could come up and hit your head on the diving board. And with goggles probably because they could fall off while diving and break and then you may have pieces floating in the pool. I've seen that most public pools don't allow at least life jackets on their diving board and thats why only experienced swimmers should be using them.

Q:What's a fire retardant carpet? Flame retardant carpet grades are divided into several kinds
At present, building materials fire retardant carpet, there are 5 grades:Class A1: non flammable building materials, almost no burning material, no fire, no smoke and dust.Class A2: non flammable building materials that produce hardly any burning materials and produce a lot of smoke and dust.Class B1: nonflammable building materials, nonflammable materials have good flame retardant effect. It is difficult to fire when exposed to flame or high temperature in air. It will not spread quickly and will stop burning immediately when the fire source is removed.B2 grade: flammable building materials, flammable materials have certain flame retardant effect. In case of fire or air will immediately burst into flames at high temperature, easily lead to the spread of fire, such as wood, wooden frame, wooden beams, wooden stairs etc..B3 grade: flammable building materials, without any flame retardant effect, easy to burn, fire risk is great.Fireproof carpet is generally used in 4 star above hotels, high-grade office buildings, leisure and entertainment, especially the hotel carpet particularly demanding.Wuxi hotel carpet if you want to fire B1, are generally selected Axminster carpets, and more than 1200 grams of nylon color printing blanket, nylon PVC carpet tile, wool carpets.  According to GB8624-2006 "building materials and products combustion performance classification", the flame retardant performance of carpet can be divided into B1 class and B2 class. The B1 class is subdivided into Bf1 and Cf1, and B2 is subdivided into Df1 and Ef1.
Q:Why does my smoke detector keep going off?
The distance to park away from a fire hydrant is usually determined by state or local codes and rules. Some areas may be as little as 5 feet, others it can be up to 10 or 15 feet each direction. As for calling the fire department, most firefighters will not help because code enforcement or traffic enforcment is not with in their job or with in their legal realm. Your best bet would be to talk to either your local code enfocement officer (call city) or local police department (city or county) and they can either deal with it or let you know who is dealing with it. As a firefighter, I see 10 feet as being a reasonable distance from a hydrant, so you might be better to go after them for being a nusance for being in the road.
