Holes \ will be drilled in concrete 4' O.C. horizontally, and lead shields will \ be inserted. 5/16" x 3-1/2" lag screws will be used to attach sleepers. .v Johns-Manvilie J-X 2" Blanket will be cemented between sleepers using .

Dense white fumes are evolved during the process, leading to contamination of the furnace rooms, where fatal conditions have resulted.

Under this program a new flat wall vehicle has been developed which will have better odor than the previous material. 4) Development of non-chalking white, Y-l892 - Trim White was developed as a non-chalking white for trim and to serve as a shading base for painters for light tints, 5) House paint tests have been exposed with lower lead content and we expect to further reduce the cost of our house paint in the near future.

The problem with which you appear to be faced may be a difficult one for economic reasons, since the industrial people concerned with the reclamation of used lead appear to have some difficulty in making a profit unless they cut corners.

Pipes made of cpper, brass, or lead may usually be classified as smooth.

Certain conclusions appear valid at the present time* Ho agent which is an effective wetting agent for CPC in water has been effective by itself in grinding water-borax mixtures* The only ' agents which have been effective alone are poor wetting agents but generally known as good dispersing agents for aqueous slurries, such as Blancol and DaxadXI (formaldehyde condensation products of naphthalene sulfonic acid derivatives), Marasperse CD (composition unknown) and carboxy methyl cellulose* Recently attempts have been made to use combinations of wetting and dispersing agents with some evidence of improved repro ducibility and some slight improvement in strength obtained* Finally, some of these recent leads were applied in a series of regular ball mill grinds in which a remarkable advance was made where borax was included in grinds containing Blancol* The role of the borax is not clear, but it could not be replaced with either NH40H or HaOH* Xylene deflocculation Was not effective in improving the strength of products ground with Blancol* * * Semi-Works studies on H.F* Grinding included two trials of grinding crude Green press cake in acetone-borax mixtures and good strength was developed in from 1 to 2 hours* However, the hue was distinctly bluer than that of GT-674-D, lot 430* The presence of chromate in the grind appeared without significance* This deserves more study* *2 Two grinds were made using chlorine-free crude press cake* One, made with press cake from sulfated crude, was very slow in changing phase and was quite weak at the end of 8 hours* The other, Rising steam distilled crude press cake, appeared to he in the beta gjphase throughout and reached the strength of BT-297-D, lot 373 in about 2 hours with no evidence of advantage in grinding longer* There was some tendency to dullness b&t this type of process may deserve more attention* AJSsMPH DUP05006916'

Few positive reactions occurred with ' lead and calcium arsenates, on account of their low solubility..

This, in turn, would lead us to the discussion of milk and the lactic acid forming bacteria.
