Award For Best Answer

 * Thanks, 33. I really appreciate the feedback. The moral of the story: on the Reference Desk, it's better to direct the questioner to the right article on Wikipedia than to try to explain everything all over again. Best wishes, --Heron (talk) 09:26, 28 January 2009 (UTC)

noise spectra images: thanks
Thanks for finding that other white noise image. I think we've reverted everything that needs it. Baccyak4H (Yak!) 19:30, 25 February 2009 (UTC)


 * Cool. I had a quick look at the Brown noise and purple noise plots, and they seemed to be about right. --Heron (talk) 19:39, 25 February 2009 (UTC)


 * I disagree with your pink noise plot. Pink noise is constant energy per %age bandwidth and so an FFT should FALL with frequency. Can you check this please? Greglocock (talk) 01:27, 26 February 2009 (UTC)


 * The plot is correct. The response falls with frequency if you use a linear frequency axis, but this plot has a log frequency axis and is therefore flat. (Well, actually, it rises slightly, but I think that's just due to inaccuracy in the calculation.) Please see Colors of noise, which confirms what I just wrote. --Heron (talk) 19:46, 26 February 2009 (UTC)


 * No it should depend on the sampling algorithm not the axis display. You can see this for yourself from the definition. If you use an FFT then white noise should be flat, pink noise falls as 1/f. Greglocock (talk) 03:32, 27 February 2009 (UTC)


 * Looks like you are right, Greg. My apologies.  Pink noise should fall off at 10 dB/decade.  I'll see if I can find a suitable image to replace the bad one.  Thanks for pointing out my error. --Heron (talk) 09:47, 27 February 2009 (UTC)

Shaft collar
Thanks for adding a photo to this article, however, I'm not sure that what's pictured is a shaft collar because it's part of the gear. As I understand a shaft collar, it's a separate entity, and I believe that's the way the article states it as well. Let me know your thoughts. Wizard191 (talk) 22:31, 7 March 2009 (UTC)


 * You're quite right. I misread the article. Thanks for explaining it to me. I've just removed the photo. Looks like I need to buy a bigger Meccano set! --Heron (talk) 23:02, 7 March 2009 (UTC)


 * It's all good. Thanks for the quick reply! Wizard191 (talk) 23:38, 7 March 2009 (UTC)

 * Which edit are you referring to? --Heron (talk) 18:56, 22 May 2009 (UTC)
 * Oh, never mind, I see which one you reverted. Your automated comment is not appropriate to this situation, so I'm going to do the edit again. I will be happy to discuss my edit with you if you want to. Best wishes, --Heron (talk) 19:06, 22 May 2009 (UTC)


 * Hello Heron, just dropping you a quick note to let you know I commented on Pekayer11's talk page about his use of rollback and his use of an inaccurate template. No need for you to comment there, but since it directly related to your edits I thought I should let you know that I brought it up with the editor (I have the page watchlisted which is how I saw the reversions in the first place). Please leave me a talkback notice if you reply to me here, thanks. The   Seeker 4   Talk  19:31, 22 May 2009 (UTC)
 * Thanks for the note. I read his/her talk page and noticed that I wasn't the only one disagreeing with his reverts. I don't want to be too critical of him at this early stage, so I'll ignore this incident unless a nuisance develops. Oh, and more thanks for alerting me to the existence of the talkback template! --Heron (talk) 20:34, 22 May 2009 (UTC)

Updating the "flush toilet" article, could you help out a bit?
Hi Heron, I couldn't help but notice that you have made some good contributions to the Wikipedia "Flush toilet" article over the years. I am an American plumber, who has traveled a small bit around the world, and who is only somewhat familiar with British and continental toilets. As such, I have recently significantly re-organized and edited this article. In doing so, I have tried to the best of my ability to accurately represent the status of the toilet industry in the UK and the continent, but unfortunately I have had to make a few 'educated guesses' along the way. From the nature of your contributions to Wikipedia, I am guessing that you are most probably a Brit, and thus I was wondering if you might be able to check out my assumptions in the article, particularly about the prevalence of true "siphon-style" toilets, and of the prevalence of flapper-flush-valve toilets in both the UK and on the continent. I know that up until the last few decades, true siphon-style toilets were quite rare in the UK and in the continent, but I am wondering if the American type siphon-style toilets and flapper-flush-valves might be making inroads into these two markets. If you might have time, could you kindly review the the newly revised "Flush toilet" article for accuracy on these and other points? Sincerely, Scott P. (talk) 23:56, 30 May 2009 (UTC)


 * Hi Scott. Thanks for your interest. I like the way that the article is becoming more international, although it still has a long way to go. I will make a few small changes to the article, but it seems mostly OK. My only disagreement is with the statement that bowls outside the USA are mostly of the non-siphon type. I have seen (or rather heard) many siphon-type bowls in the UK over the last 40 years, and I had assumed that they were universal in the UK. However, you have made me realise that many modern bowls don't make a gurgling noise, so perhaps there has been a silent revolution here, with washdown types replacing siphon types.


 * As for the tank flush mechanism, the siphon type is the most common in older houses in the UK. I have seen the flapper type in South East Asia, and it may be in use in newer houses here too, but I am not aware of it. I shall see if I can find any evidence of this. --Heron (talk) 12:35, 31 May 2009 (UTC)


 * Thanks for your generous help with this. I must say that I am curious as to the true relationship between the washdown and the siphon type toilet.  Unfortunately getting to the bottom of this question is also somewhat complicated by the fact that there seems to be a general lack of understanding regarding the topic, even amongst plumbers and plumbing sales people.  Furthermore, there is also a lack of a standardized vocabulary just to enable meaningful discussion of the subject!  For example on the Kohler USA website, a "washdown" toilet is defined as a siphoning toilet, yet I've seen washdown toilets defined in most other places as non-siphoning toilets.  I think I'll opt against Kohler on this one.  Since I wrote you I've trawled the Armitage Shanks (A/S) website and found that all of the toilets I found there were of the "washdown" style.  Apparently A/S is the largest toilet manufacturer in the UK, so I think it's probably safe to assume that this style is the most popular in the UK.


 * For whatever it may (or may not) be worth, I would think that a properly designed washdown toilet would probably be more maintenance free than a siphoning style toilet, at least in the bowl department. I am guessing this, due to the much larger waterway that is found in a washdown toilet.  Typically, siphoning toilets here in the US seem to all need to have a plunger kept somewhere nearby, for that inescapable eventuality, the dreaded "clog".  My guess is that you folks over there have no such need with your washdown toilets.  Am I correct in this theory?  As you wrote earlier, perhaps the siphoning style toilets were tried in the UK for some time, then abandoned?  Who knows?  The "down-side" that I would imagine for the washdown style toilet would be the possibility that occasionally it might have to be flushed more than once, in order to fully clear the bowl, due to the fact that the surface of the water in the bowl never goes lower than the top of the drain inlet, as it does in a siphon-style toilet.  Personally I would much rather have to simply flush a second time, than to have to face the dreaded "clog", which requires multiple flushes anyways!


 * I know that the flush of a UK washdown toilet seems to me to be rather loud, efficient sounding and all, but amongst all of that noise, I don't think the last bit of the flush includes that noise signifying the breaking of the siphon. Perhaps you never differentiated before?  As far as toilets on the continent, I only have a few clues.  I know that a German made toilet that I recently installed here in the US was a siphoning style toilet, and I am guessing that perhaps most of the continent uses the siphoning style.  This is something that perhaps I will try to verify with some ceramics manufacturers from the continent.


 * I'll look forward to your reply.


 * Thanks much, Scott P. (talk) 23:03, 31 May 2009 (UTC)


 * Well, I've now become a toilet bowl spotter. The two in my house are both from Armitage Shanks. The older one is a siphon type, judging by the sound, and the newer one is a washdown.


 * On the subject of clogging, I have not experienced a clogged toilet in a private house in the UK since the 1970s, so something must have improved since then. I think we have now arrived at the limit of my knowledge on this subject, so I'm not sure that I can help you any more, but feel free to ask. --Heron (talk) 19:01, 2 June 2009 (UTC)

Innovative ideas
Hi! heron. I would like you to give some ideas on future studies in electronics that helps students in current scenario to come with innovative ideas. --n9t8 17:45, 5 June 2009 (UTC) —Preceding unsigned comment added by N9t8 (talk • contribs)


 * Hi N9t8. You will need to explain your question a bit more carefully before I can help you. Are you asking me to think of research projects for students? Or do you want to know about methods of teaching? I am not an expert in either of these areas, but I could try to give you some ideas if you want. Or, more likely, I could point you in the direction of some better source of information. --Heron (talk) 19:30, 5 June 2009 (UTC)
