S. Kevlin New York . Central Files Product Development 1. Stress Corrosion The only major deficiency of stress corrosion ware to show in the recently conducted test market program was softness up Products made from the Product Testing Lab approved 10L batch are not as hard as standard Kaylo Efforts are being directed toward properties of the stress corrosion product via canent upgrading physical of the batch modifications . Batch formulations containing various percentages of - cament and various S ratios were poured and samples submitted to Product Testing for evaluation Manufacturing decided 2397 glass used in to go outside the company to obtain the proprie stress corrosion batch formulations The Legal Department Quartz prepared and Toledo General Purchasing submitted to Philadelphia & secrecy agreement covering disclosure of the proprietary composition of 2399 glass Philadelphis Quarts signed the secrecy agree- ment and a meeting was set up in Philadelphia for August 1 to discuss the technical aspects of the product R. Shannon was assigned by Toledo Purchasing and Manufacturing to represent OCF at this meeting 2. Replacement of Asbestos The search for substitutes for asbestos fibers was temporarily delayed A beavy vacation schedule reduced overall activity in the Laylo R & D Laboratory Also per agreement with Marketing priority vas assigned to the stress corrosion program Samples of Kaylo reinforced with glass and submitted to Product Testing for hot pipe tests in June have not been tested to date 3. Competitive Insulations Recent testing of competitive insulations indicate products of several of our competitors have deteriorated in recent months in thermal condustiv- ity and in shrinkage at maximum recommended temperature usages . ze: At the request of Marketing June 14 Kayle Team Meeting a report 3s > umrizing umrizing Marketing thermal physical properties of competitive high tempera- ture core pipe and block insulations was completed and submitted to I and C Marketing personnel PLAINTIFF'S EXHIBIT Blumberg 698 01 027 0356 339 Kr L.

Canadian Manufacturoef Kayle or manufacture in Canada This we did and comments were written and suggestions made within the confines of the Legal Department's clarifica- tion of the scope of the agreement between CCF and FCL & Fiberglas Candda Limited for their personnel to request visit Berlin by by the Legal Department Overman was denied ce Process Development 1. Process Audit Productivity and job officiencies have dropped drastically at Berlin during the past several months Manufacturing requested the assistance of R. Shannon to make an depth audit of the plant process to determine causes for lower throughput and job officiencies This audit started in July and extending inte August will require a major effort on the part of the Kaylo R Laboratory and may delay other planned and timing including activity on stress corrosion and programs asbestos substitutes for A major cause for offvare at Berlin is recent loss of whole trains of material due to softness of vare In most cases the cause was traced back to errors in mixing or malfunctioning equipment Another cause of software software is incorrect S ratio for cycle used An possible Laboratory study was made to determine optimm S ratios for extensive both 1-10 and 17 batch The results of these studies indicated the using higher than desired S ratios for optimum strengths plant was Flant evaluation of Lover S ratio batch formulations are under my - = 2. 20 o Over the years the major cause for 17 20 offware has been XIX notnot enough material This is causedcaused movement of the batch after it is in the mold and eccurs when the molds are transported from station to station within the plant we . ; 01 027 0357 340
