    Cork-resin ablative insulation for complex surfaces and method for applying the same

    Get PDF
    A method of applying cork-resin ablative insulation material to complex curved surfaces is disclosed. The material is prepared by mixing finely divided cork with a B-stage curable thermosetting resin, forming the resulting mixture into a block, B-stage curing the resin-containing block, and slicing the block into sheets. The B-stage cured sheet is shaped to conform to the surface being insulated, and further curing is then performed. Curing of the resins only to B-stage before shaping enables application of sheet material to complex curved surfaces and avoids limitations and disadvantages presented in handling of fully cured sheet material

    The Atchison. Topeka and Santa Fe Railway System.Railway Exchange, 9 Jackson Boulevard, Chicago.W. J. BLACK,Passenger Traffic Manager.OFFICE OF PASSENGER TRAFFIC MANAGER.W. H. SIMPSON,Advertising Agent.Chicago, May 31,1906.New DISCOVERIES PETRIFIED FORESTMr. john Muir,Martinez, California. Dear Mr. Muir:Your favor May 20th received, enclosing sketch of the various deposits in the Petrified Forest and describing the new discoveries made toy you in the vicinity of Adamana.Am very much obliged for this information, which will be of great use in our advertising. If I go west this summer will make it a point to visit the new sections. What you say about the age of the petrified trees is very interesting; also the fact that they probably grew where they now are.As you may know, a bill is now before Congress to set aside the Petrified Forest as a national park, thus preserving it to the people of the country for all time to come. The area included only comprises what are popularly known as the first, second and thirdforests. It looks as though the recently discovered Blue and NorthSigillaria Forests, ought to be likewise included.Would you also recommend that Bibo Grove, eight miles east of Adamana and the three Sigillaria Groves, lying between four and five miles Northeast of Adamana should be brought in with the others, or are they of minor value?Should you again wish to visit Adamana, will be glad to furnish you with transportation over the Santa Fe, unless that item has already been arranged by Mr. Byrne or Mr. Gregory.Yours truly,[illegible]Cy-GTN-JJB-WJB0373463 73
