ACTION TAKEN OH REGULAR AGENDA: S-13-B TEMPERATURE GRADIENT COMPARATOR E-37-A Mr. Riggins will write Mr. Geo. Cohaugh, of Herbi*on-Walker, for gradients and samples of their material and Mr. Harden will test and evaluate the resales as outlined on previous Laboratory Reports. Messrs. John Eosbela and mgg<TM will /h<rWj discuss patent application within the nest several weeks. DEVELOPMENT OF "MS" HALLS AND A&CSES - MODELS ui tW.. A**'4 ;i Under this elasaifieatloo current models have been esogplaead with >tha exception of the proposed Plastic Firebrick noee. Castings for this construction, have been designed but are not yet available. CMilUvullc Qit suALL J^tcL+u- (9 S-36-B ABRBSXST CEMEHT Materials still to he teeted are "Amanita" by Ealleaite and Resin Cement "S" by Callcote. Other sceples svaliable era by Flintkote. Mr. Harden developed a Limite cement base anterial which ia workable far 1% hours and has a complete set in 3 hours. This cement was tasted by Mr. R. Ho*bein but no report is avail able. The "Xarbo" neterlsl now at the plane requires several additives which. If not used carefully, oould result la e violent reaction. Before proceeding with tbs teat of "Karbo" Mr. Bruce Abell will be consulted on the proper procedure in safely hand ling these netarials. K-3B-A DRTUB COT DATA This prajeet requires one additional test before completion at which tine s full report will be submitted. The following tests, on wall sections, have now been completed: 1. Using Calcrete "40" (24hr.ewre) 800 F Set Face 2. Using Decrees "40" (24hr.eum) 800 F Hot Face 3. Using Decrees "40"( 7 day cure) 800 +1000 F Hot Face 4. Using Calcrete "40" (72br.eure) 1000 F Hot Face Still to be tasted: S.

One was vr\.\ Kc the Consistency Test and the other the Shrinkage Test. Under the Consistency Test there are ewe acceptable Methods out lined under ASTM standards designated as Methods "A" and "B" We have equlpnent for testing under Method "A" whereas our cenpeeitors use Method "B". A eonperlson of results ob N: 7^ ,^ tained fron these tests show sene variance. Because of these inconsistencies the Bureau of Ships has indicated it can re- s# nova these teat requireaents tesqwrerily and Mr. Clousing will Vs t * irequest than to do this. Under Shrinkage Teata - Mr. Speelaea reported that Bentonite < -N Clay, aa received, has always checked out within the specifi >|tfjcations as sat up by the Supplier and Mr. Abell. Because of excessive shrinkage, tests were nade an other eenents requir ing Bentonite and these also indicated a greater shrinkage. This procedure apparently Indicated the clay was at fault. Therefore samples ware returned to the Supplier for further teetiag.^ Because of large purchases by Hsval and other emtd services, Mr. Clousing will neks a detailed study of these specifica tions and datemine uhat available equipoant ws have for east ing under Havy Specifications and what other equipnent will be required and the approadnste coat. Mr. Pohl will arrange to obtain a hag of Kagle "66" for testing purposes. B2-B 7TBOSCAT Mr. Spaalnaa read a copy of a latcar written by Mr. H. 0. Lock of Bow Cheaieel Service and Developnent Department, addressed to McKaaaon-lohhlna relative to an additive known ee "Mathoeel" for reducing checkering sad erasing on fyroscat.
