Abell Gsntlerrm: Heating was called to order at 10ti5 A.M. on June 6, 1957 in th9 Aurora Conference Eoou, The next seating vill be held at the sane place on. Jul7 11th, 1957 due to the July 4th holiday weekend. Tho nev 711 Insulating Cesent sample bags are here and in use, A discussion of sewing vs wire tie on the considerable auaber of 5# Utility Finish bags '.as held and it vas decided to cut approximately four inches ires the top of the bag and then sev than without trying to fora a gussst. 1. E2-A - Sot Strength Testing, John Eoscein is afraid of cutting into the stack per Dan Fin's study sketch of .vi-7 22, 1957. Ho talked viik Earl Davis >-ho stated that a siaple aspirating burner night bo a 'cotter choice then a H;.on Presix. Earl also suggested v/ating this furnace directly into the atmosphere of the roaa. This suggestion ves deossd impractical, due to ths voodea floor structure directly above the test unit and vho rslciiveiy snail cubical content of the roaa in which th? structure would be. Earl then suggested a hood arrangement -ranted into the stack via snail openings and taking in a great deal of cold air so that ve would not need tba large amounts of insulation cm such an elaborate flus structure. 1. If. Higgins is to visit Esyes Laboratory at H-V. in Pitts burg to observo this type of furnace end see hsv they handle the venting problem. On using an oapirating type burner vs would bo liaitad to negative pressures in this unit and would be forced to forgo ths plus pressure tests that vers saigimllv. planned. Ed Harden suggested the possibility of a tunnel under ths stack base ccaing up in the niddlo So that all of the hot gases would bs kept away frea the seta! portions of the stack. Bob Higgins will be in Pittsburgh during the week of June 10, 1957 and vill discuss this project completely with Earl Daria and John Hosbeiu. Va will new wait vith a ay purchases on this project until more iafonaatioc is received frea this soafersacs. R. B. Aball vLll check with Naxoa on their safety recosaandc-tions, purge cycles, etc., end also with ths Eclipse Fuel Ccnpany in Rockford vho nak-3 -the aspirating tyue bumsr. 2.

This installation should be finished by July 16th at the end of cur vacation shut down/ B. ASTM proposed hendleability equipment is ready for use now. We ..ill test block 6sn36* storting with l$a3 2a and 3a thickness to 'try obtain a correlation between thicknesses.

Exploratory tests using small Roots blower for vacuum pumps removed 6ne f pounds of water per board foot of block at 5-6* of vacuum. Veter removed at block machine materially increases'drying production .and reduces costs, j * J. t.. -r* VC. r / 1. 9. P2-A Slug Free Wool and Snot Reduction. To improve on our naw slug separating system we need a more constant feed to the wool granulator. The new beat resisting steel divider was put in service June 5, 1957.- Work on using shot in cupola is continuing also consider ing the possibility of screening and grading shot for sand blasting usage. 10. E2-B Pyroscat Work in progress. 1-2-4 Concrete ebsorbed 9$ of water by weight (135r/cu. ft.) while Pyroscat absorbed 55% b7 weight (50#/cu. ft.) During the first forty eight hours both lost 60$ of their total water, that is the concrete lost 7.3?/ cu. ft, while Pyroscat lost 16.5#/ cu. ft. As scon as this report is finished it will be forwarded to Dick Moore in cur Cleveland office. 11. D4-A Utility Finish. 1. il&vy specifications. Work in progress. 2. Finish for highly absorbent material. Work in progress, 3. Paining qualities vs 8me coat. 50# of SS2 tried at Ft.

Our present greatest need for a new block is one that will meet ASTM spec C333-5AI for DE block and Harry Levis also suggested that this specification be used as a yard stick for our future work on this project, a considerable discussion vss held on the basic premises of this entire project reviewing its history and vhat trends the Committee thought the project should tak9. Mr. Harden "trill present the economics of his varaiculite block, mentioned in previous minutes, at a future meeting.
