Two of these bulletins were circulated* 2 3 * * 6 7 to members In this quarter. 2. ASHE. The Secretary attended the annual meeting of the American Institute of Mining, Metallurgical and Petroleum Engineers In St. Louis. 3. Annuau. "~-tlng. Arrargenc^lu ver- virtually completed for the Annual M-e-Mng nf t Ma, May 2-3, and for an Interesting program. U. Annual Review. The Secretary's annual review of the lead situation was prepared for "Engineering and Mining Journal" and appeared In the February Issue. Reprints were distributed to members. 3. Statistics. Data on lead statistics were prepared and supplied to the "American Metal Market" for inclusion In their annual publication, "Metal Statistics." 6. "Iron Age."

At the Instigation of the Secretary, meeting was held In Pittsburgh with the Research Ccmlttee of the U. 3. Potters Association end Dr. Robert A. Kehoe In connection with recent poisonings from improperly fired lead-glazed pottery. As a result. Dr. Kehoe and hit associates aro conducting tests on pottery made by a variety of manufacturers and will use the results to establish standard test methods and tolerances for lead that will be universally acceptable. The work It being Jointly financed by the Potters Association and LIA In the hope that it will develop acceptable procedures without government intervention and avoid restrictive legislation In the use of lead in glaze*. i iii i ih Quarterly Report of the Secretary January 1 to March 31* l?6l -2- April 3, 1961 8. ASA Comlttee. LIA vaa represented at another meeting of the ASA comittee dealing with childhood lead poisoning and la supplying secretarial service for this coccittee. 9. Milwaukee law Suit. Trial of the suit involving alleged lead poisoning from water pipes in a Milwaukee apartment building, mentioned in several of our previous reports and in which ve are cooperating with the defendant in compiling evidence favorable to lead, has again been postponed from the last week in January to May. Latest inforcation ve have been able to get Is that the plaintiff la not anxious to see the case brought to trial because of the weakness of her case. 10. Lead Poisoning from Red Lead. Another case due for immediate trial'has been brought against the Delaware River Port Authority by several painters claiming lead poisoning from spray painting the Delaware Rivor Bridge at Philadelphia with a standard red lead paint. We have been cooperating with defense attorneys In gathering evidence and ob taining expert witnesses. This case has been long drawn out and has been referred to previously, but is now due for trial. PiPUSTBT DEVELOPMENT--CSSm 11. Architectural Consultant. LIA has engaged the full time ser vices of Edwin D. Martin to provide better service to architects and promote the use of lead products In construction. Mr. Martin studied architecture at Yale, from which he graduated in 1935* He has worked with several of Hew York1 a leading architectural firms in his 25 year* of architectural practice. 12. "Lead," The first 1961 issue of this quarterly was prepared for calling In April. A brand new modernized cover was designed better to reflect the modern image of lead. 13. Advertising. Two one-page ads in our Newsletter series appeared in "Materials in Design Engineering" and one in "Product Engineering." It. 'Lead--Its Alloys and Compounds." This was the title of the annual review of technical developments in lead which vas prepared and appeared in the January Issue of "Industrial and Engineering Chemistry." Reprints were distributed to members and a selected list of 1,600 name*. 15, Home Builders Exhibit. LIA had Its usual exhibit booth at the annual Rational Ecce Builders Show in Chicago. The display embraced * vide variety of lead products that are or may be used In home construction. 16. Design Engineering Show. Wort was begun on the adaptation of our exhibit to be used at the Design Engineering Show, which will be held In Detroit In May. in --j * m igu'<" ye* iwmm wtwww* LI A2AA93 Quarterly Report of the Secretary January 1 to March 11, 1961 -3- O April 3, 19^1 17- Thermoelectricity.

A meeting of this cremittee vaa held in March* Final approval vaa given the material for a nev Technical Letter designed to consolidate current reconsendatlons for red lead paints for various purposes contained in earlier Technical Letters new out of print. An outline for a Lead Pigments Manual vaa also prepared and recanmendatlcms made for a series of Technical Kevs Letters reporting nev and experimental pigment developments. 19. Advertising. Two ads cn anticorrosive lead pigments appeared in "Engineering Nevs-Record" and one in "Marine Engineering/Log." DTOSTRY DEVELOPMENT--BOISE ARP VTBP-ATIOS SO. Insurance Companies. At our .v^estion, the Association of Casualty and Surety Companies and the Association of Mutual Casualty 0 Companies both distributed copies .f our sound barrier report to their members. We supplied nearly 400 copies far this purpose. 21. Advertising. The first ad in a nev series to appear In "Progressive Architecture" and "Machine Design" vaa prepared. It deals vlth noise control. The same ad appeared in March In our regular aeries in "Engineering Revs-Record. " 22. "Lead-Asbestos Pads Isolate Cooling Tovcr Vibrations," Reprints vere obtained of an article vith this title by A1 Leichtmaa of Weinberger, Frierson, Leichtmaa and Quinn, Rev York consulting engineers, vhich appeared in the January issue of "Air Conditioning, Keating and Ventilating." They vere distributed to our calling list of architects and engineers concerned vith building construction. 23. Aatlvlbrntlon Data. Considerable time has been devoted to sa Intensive study of nil available data on the performance of lead-asbestes antivibration pads under both building foundations and machinery. A re port on this study is being prepared. It is hoped that this study vill reveal reliable engineering data vhich vill help engineers us* these pads most effectively and provide LIA vith munition for encouraging vlder use of the pads. 2U. B1overs. We haru prevailed _*ioo Buffalo Forge Co. to experiment in their ovn laboratories vith certain lead products as noise-reducing materlsls on their blotters. T -mm' mmmm mutm* mating! n.
