It gives mssisue protection against toxic dusts, to the perodLssabla limits of lead, plus fibrosis dusts.

Afterwards on several occasions the cooling unit was put in service again, however, leading to the same undesired, condition.

The process leads to the existing level instruments on the fresh VCM receivers will be heat traced and insulated. 3- Revisions to the standard operating procedure have been made to require termina tion of polymerization with the emergency kill system if the reactor pressure reaches 1^5 PSIG during production of 5385 grade resin.

These data lead to the conclusion that in relation to mesolhul i cr..a crocidolite is more carcinogenic than chrysotilc or. amosite.

UMMARY OF THE INVENTION I have discovered that railroad brake shoes that meet AAR (Association of American Railroads) standards for brake shoes can be made from compositions having a low, non-asbestos fiber content which includes synthetic fiber The friction matenals according to this invention compnse, by weight, 0 5-11 0% non-asbestos fiber, including at least 0 5% synthetic fiber, 66-81% filler and 14-21% organic binder A preferred embodiment of this composition friction material for railroad car use contains 2 73 5% synthetic fiber, 74-82% filler and 16-19% organic binder DETAILED DESCRIPTION OF THE INVENTION The criterion for suitability of a composition friction material for railroad car brake shoe use is the ability of the friction material to pass the standards set forth in the A A R Specification M-926-72, Feb 13, 1973 Revision Some of the pertinent dynamometer performance test criteria called for m this AAR Specification are as follows. 1 Instantaneous Retarding Force During 45 Minute Dynamometer Drag Test Drag Heavy load Light load Retarding Force 400 lbs min 300 lbs mm 2 Static Coefficient of Friction 9 Test Average--0 38 mm 3 Stop Distances From 90, 70, 50, 30, 10 mph Under Light and Heavy Brake Shoe Loads (all stop distances must be within varying tolerances) 4 Wear Loss Drag Tests (total)-O 60 in sup 3 max Test Stops (total per sequence)--1 20 in sup 3 max As used herein, the term "synthetic fiber" means fiber made from a substance which does not naturally occur in a fibrous state and includes glass, polyester and kaowool The term "synthetic fiber" excludes all forms of cellulose, which naturally occurs in a fibrous state, but which can also be processed into a different fibrous form (e g , rayon) Some example mixes used a single type of synthetic fiber, while others used several types of synthetic fibers in combination Other example mixes contained a mixture of synthetic and cellulose fibers All mixes were totally free of asbestos and lead Organic binders, such as styrene butadiene rubber (SBR), nitrile butadiene rubber (NBR) and modified phenolic and cashew resins were used Cunng agents for the organic binders included sulfur, zinc oxide and hexamethylene tetramine http //patft uspto gov/netacgi/nph-Parser9Sectl=PT02&Sect2=HITOFF&u=/netahtml/sea 10/18/2003

This leads me to conclude that the numbering scheme shown in the second set of reports is correct.

Releases requested prior to this date will be shipped at present price levels assuming proper lead times were given.

As a result of this the three leading Companies in the asbestos industry, B.B.A.

The statement on ventilation appears to us to lead towards misunderstanding.

OREtCC PPoollyyvvinyl Chloride Task Force From: p Brooks, Bill Nichols Preliminary explorations both with the companies and with appropriate people in OSHA indicate that the recently reported additional research results------namely that white mice have incurred angiosarcoma of the liver at a concentration of 50 ppm of polyvinyl chloride ------ lead to the tentative con clusion that the proposed mortality study of users of polyvinyl chloride (fabricators, processors, etc.) is more important than ev r, provided that it can be done within a very limited time frame.
