Die neuesten Ergebnisse der Ultraschall-Forschung in Anwendung und Ausblick auf die moderne Technik by Reimar Pohlman Estimated delivery 3-12 business days Format Paperback Condition Brand New Description Theoretical considerations and experimental references are introduced to show that the science of supersonics is not so much a matter of the inaudible sounds themselves as essentially of their practical applications in the new "mechanical high-frequency techniques": these lie predomin antly in liquids and solids. Apart from underwater communications, one of the oldest fields of application for ultrasonics is the testing of materials for flaws. This technique has been considerably developed in recent years. Fully automatic testing devices for coarse and fine pressed steel, metal strip, tubes, round sections and wire are shown, and their mechanism explained. An important place in industry today is taken by high-frequency cleaning. It is now possible to clean inaccessible machine parts without any manual intervention: the cleaning of machine interiors is also possible, since high-frequency vibrations can to a large extent penetrate machine walls. Ways of ensuring the best possible sound wave permeability are being discussed. It is further demonstrated that even indismantled parts can be satisfactorily cleaned in ultrasonically charged baths, a fact which is of great importance for all re-assembly work Publisher Description Theoretical considerations and experimental references are introduced to show that the science of supersonics is not so much a matter of the inaudible sounds themselves as essentially of their practical applications in the new "mechanical high-frequency techniques" these lie predomin- antly in liquids and solids.

Seller sent me the wrong book, but the book they sent sounded interesting enough for me to keep it. I still contacted the seller and communication was fast and professional. They apologized for sending me the wrong book and said I could return it for a refund. I told them that I liked the book they sent me and wanted to keep it. They were happy. Told them thank you and happy new year. People make mistakes, but the fact that this seller was quick and professional and apologized made a difference.
The basket is perfectly what I ordered and as listed. It came in the factory packaging and was perfect upon delivery. Thank you postal service lol. The delivery took way longer than listed though, it was listed to come in a week from purchase, but took a whole month. I had some concerns at first, but communication with the company was top notch and they were very professional and answered most of my questions satisfyingly. Just prepare for a longer wait than listed, but I got what I bought lol.
The two new out-of-print books I ordered were exactly as described and shipped promptly. I did ask the seller's support person (an AI chatbot, I think) to be sure to package the items carefully, and "he" said that he'd make that request of the shipping department. I knew this was hooey, and as I expected, the books were shipped in nothing but a padded paper mailer, no other protection. I got lucky, no damage, but don't bother making special requests of this seller.
