This book was released on 2018-07-11 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flight 5 aft segments with nozzles were exposed to -17 F temperatures while awaiting shipment to KSC in February, 1989. No records were found which show that any previous nozzles were exposed to air temperatures as low as those seen by the Flight 5 nozzles. Thermal analysis shows that the temperature of the fixed housing, and forward and aft exit cone components dropped as low as -10 F. Structural analysis of the nozzles at these low temperatures show the forward and aft exit cone adhesive bonds to have a positive margin of safety, based on a 2.0 safety factor. These analyses show the normal and shear stresses in the fixed housing bond as low values. However, the hoop and meridinal stresses were predicted to be in the 4000 psi range; the failure stress allowable of EA913NA adhesive at -7 F. If the bonds did break in directions perpendicular to the surfaces, called bond crazing, no normal bond strength would be lost. Testing was conducted in two phases, showing that no degradation to the adhesive bonds occurred while the Flight 5 nozzles were subjected to subzero temperatures. The results of these tests are documented. Phase 1 testing cooled a full-scale RSRM insulated fixed housing to -13 F, with extensive bondline inspections. Phase 2 testing cooled the witness panel adhesive tensile buttions to -13 F, with failure strengths recorded before, during, and after the cooldown. Bolieau, D. J. Unspecified Center NAS8-30490...

Download or read book Phenolic Resins A Century of Progress written by Louis Pilato and published by Springer Science & Business Media. This book was released on 2010-03-10 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: The legacy of Leo Hendrik Baekeland and his development of phenol formal- hyde resins are recognized as the cornerstone of the Plastics Industry in the early twentieth century, and phenolic resins continue to ?ourish after a century of robust growth. On July 13, 1907, Baekeland ?led his “heat and pressure” patent related to the processing of phenol formaldehyde resins and identi?ed their unique utility in a plethora of applications. The year 2010 marks the Centennial Year of the prod- tion of phenolic resins by Leo Baekeland. In 1910, Baekeland formed Bakelite GmbH and launched the manufacture of phenolic resins in Erkner in May 1910. In October 1910, General Bakelite began producing resins in Perth Amboy, New Jersey. Lastly, Baekeland collaborated with Dr. Takamine to manufacture phenolic resins in Japan in 1911. These events were instrumental in establishing the Plastics Industry and in tracing the identity to the brilliance of Dr. Leo Baekeland. Phenolic resins remain as a versatile resin system featuring either a stable, thermoplastic novolak composition that cures with a latent source of formaldehyde (hexa) or a heat reactive and perishable resole composition that cures thermally or under acidic or special basic conditions. Phenolic resins are a very large volume resin system with a worldwide volume in excess of 5 million tons/year, and its growth is related to the gross national product (GNP) growth rate globally.

Download or read book Complications in Regional Anesthesia and Pain Medicine written by Joseph Neal and published by Lippincott Williams & Wilkins. This book was released on 2012-07-18 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: This short text addresses complications of regional anesthesia and pain medicine. Each chapter is written by an expert in the area and follows a strict format: Definition of the complication, Scope of the problem, Pathophysiology or proposed mechanism of causation, Risk factors, Diagnostic evaluation, Prevention, Treatment and rehabilitation, Summary. Emphasis in each chapter is placed around what levels of evidence the recommendations in the chapter carry. The complications covered in regional anesthesia include complications in neuraxis and peripheral nerve blocks. There is also a section on complications associated with unintended local anesthetic destinations. The complications in pain medicine include complications of acute pain management, of sympathetic blocks, of neuraxis approaches and device placement. The first edition was published by Elsevier. They have returned copyright to Rathmell and Neal, who will turn it over to us. The audience includes anesthesiologists, pain medicine specialists, and neurologists.

Available in PDF, EPUB and Kindle. Book excerpt: The memorandum summarizes the available information on the compatibility of liquid rocket propellants with prominent materials of construction. Fuels and oxidizers of current interest are discussed. The corrosion data which are presented will apply to storing, handling, and control equipment outside of missiles and to missile components excluding combustion chamber. The compatibility of materials with reaction products in combustion chambers, nozzles, etc., is not considered. Included in the summary are data for many nonmetallic materials. The memorandum is subdivided into sections according to the propellant. Each material of construction is rated for a given medium as belonging to one of four classes, based primarily upon corrosion resistance. Consideration also is given to such factors as catalytic decomposition and sensitivity to impact.
