by ali member* or the committee and .the.topic*. presented there-in were subsequently diseussed at the oommlttee meeting.
Bauseh & Lomb Automatic Dust Counter: Hr, JP, Vronski gar* a rep< on the tests that were^conducted at the Raybestos-Hanhattan plant 1: Manhelm,?a. The attempt to find a oorrelation between the Impinger
and the Deuaeh k Lamb Duet Counter lead to the eonelusion that little oorrelation between the two instruments exists, particularly in regards to large particle else as well as in areas of high dust
concentrations. This phenomenon Is due to the low trapping velocity of the Bausoh A Lamb Ifest Counter, which Is tt trefore not to be eon eldered as a replacement for the Zmplnger, However,the Bausoh k Lon Itost Counter has proven Its feasibility as an excellent monitoring device,
Mr, C*L, Sheokler reported on the Hambrano-Piltsr Method and vll
presant a paper on that method at the next meeting.
Dust Control In the Manufacturing Process : Equipment designed for tiie reduction of dust in the various operations of textile manu facturing was extensively diseussed:
L, A bag opening, emptying and storage system, designed by Barkley k Dexter, Ino.
2, A bag dtmspcr, designed by the Vilkra Co, I 3, Bag opening and handling devices, designed by the member
companies It, Various systesis of moving blonds to oardt, 5. Balloonless spinning and twisting, 6, Vet weaving
I
One member company reported on a balloonless spinning frame based on the woolen ay stem. Balloonists spinning sesms to bs desirable
inasmuch as ths absence of a balloon results In a much lower dust
eount, Voolsn type spinning frames operate usually at a considerabl
higher spindle speed than those now being used in the asbestos tex-
tile Industry, As a rssult broksa snda will stir up a grsat deal of
dust* Zt is therefore imperative that the spindle will stop as soon
t
as an and breaks. Ths manufacturer of ths spinning fraathas designs an automatic spindle step motion and is at present experimenting
with such a device, which is similar to the one already being used
