Reading Mark's comment on a previous posting, I felt like asking people on this BBS, what are their coutermeasures by their set-ups.
The air amount from the opened register hole and its dispersion may be causes of its emission trouble.The less amount and the more dispersion,the better.
Typical counter measures may be:
#1)Register cork elevation should be minimized to around 1mm..
#2)Cork pad should have a concave of a shape enabling good air dispersion.
#3)A special shape register tube(Moennig way)
#4)Galper's device
I myself adopt #1 and #2. I do not know precisely about #3 and #4. Do they work?

I find that reeds also have an impact. For me, Mitchell Lurie reeds give noticeably better throat tones than Vandoren. So if I'm going to be playing a lot of slow, exposed throat tones, I'll simply use a Mitchell Lurie reed that day.

I admire your precision, Hiroshi.
I have found, however, that careful venting with RH fingers eliminates any need for this in my case. I did know of someone who literally cut off a portion of the register tube in their A clarinet, but I've also heard that this can lead to intonation problems.

Shortening or replacing the A clarinet register tube has more to do with subtones above the staff than the throat tones. It is a very common procedure on Buffet A clarinets.

My LeBlanc L7 has a "pinch" Bb of fine clarity, hard to tell the diff. from the A + trill key. Its reg. tube is into the bore no more than 1/4 of the diameter [about 1/8 ?]and is raised outside so that prob. the tube length is same as usual. My good friend's old [but very good] Buffet with the wrap-around [front located] tube is also raised externally, dont know re: bore tip location but will ask. There are several patents, Galper in particular[and references cited in it] which are available for reading and text-copying [drawings may not be conveniently available] via IBM or USPTO sites. I'll post the pat no shortly. Don

I believe Av Galper's patent no. is 5,241,890, the Briccialdi mechanism is 5,524,520, a Yamaha may be of interest,4,922,792, and the early Stubbins-Kasper [not easily available] is 2,508,550.. Likely some of these have been patented in Europe [EP] and world [PCT - WIPO] systems.

I agree with Robin that carefull venting will drasticaly improve the throat tone problem with most clarinets. For A and Bb, I vent using my 2nd and 3d left-hand fingers plus a little finger on the "long" B/E key. Sounds awkward, but over the years is has become "second nature" and I use them 98% of the time and have had good results on Buffet and LeBlanc clarinets. For G#, I sometimes use the third left-hand and first right-hand fingers to improve this note. On "open" G, I have been using the first and second right-hand fingers to improve and raise the pitch on my LeBlanc Concertos--strange, but it seems to help me. (When you play like I do, you need all the help you can get) Hope all this helps--good luck!!

Yep, I'd go with that, William.
But instead of the long B/E key, I find the RH C/F key is best on my instrument. And as you say, It sounds strange, but it truly does get to the stage where you can play really fast passages with these vents.

I believe that the Ridenour fingering book has lots of throat tone fingerings to help intonation. I think the posters above have found their own solutions for their horns along the same vein.
