Talk:Ultrasonic welding

message: I reworked the history section, but this article is still seriously lacking pictures.  If someone would add some it would be much appreciated.Marylee23 (talk) 14:30, 9 April 2008 (UTC)
thread_title: Pictures

message: The reference article for "the first ultrasonic welded car" is unverifiable. A car is never mentioned in that article. I was never able to find a reference to a vehicle made entirely out of ultrasonic plastic welding.  — Preceding unsigned comment added by Mazerinth (talk • contribs) 18:37, 30 November 2013 (UTC)
replies: text: The earliest reference I can find from the US Patent Office is Patent #2891180 issued in June 1959.  The patent shows the original design, and confirm that this was indeed awarded to Aeroprojects (now Sonobond).  I can't confirm if there were designs before this or if something like this existed in another country, but the above listed patent is the earliest I could find.  There are some pictures in this patent as well, but I would suggest using more recent ultrasonic welding device patents for a picture.  I actually have a picture of the process in my manufacturing textbook, but I don't know if it would be legal to scan that in or what.  128.180.77.6 (talk) 03:12, 7 April 2010 (UTC)
replies: text: Unfortunately scanning images is illegal unless it was printed before 1923 in the US. Same goes for patents. I've got an ultrasonic press here at work that I can try and take a picture of when I get a chance. Wizard191 (talk) 12:40, 7 April 2010 (UTC)
replies: text: After doing a little more patent digging, I found that #2891180 is a vibration mount, and is not the earliest such device.  The method for ultrasonic welding seems to be first mentioned in #2,522,082 in Feb 1945.  Raytheon has a patent for a general vibration device (#2,651,148) from Nov. 1949 which they claim can be used for "bonding plastics and other materials by localized heating", among other things.  The first patent to use ultrasonic welding with respect to metals was Aeroprojects (Sonobond) in April 1956, but they do not seem to be the first to pioneer this process in any other regard. I will continue to read up on patent searches and let you know how it goes.  128.180.55.169 (talk) 01:15, 9 April 2010 (UTC)

message: I think, the main point should not be "industrial technique" (this is nearly everything) but "type of friction welding" as it is seen by FW and USW specialists.--UtzOnBikeEN (talk) 19:50, 11 August 2008 (UTC)

thread_title:  What is the relationship between ultrasonic welding and heat staking? 

message: From my own personal experience as a victim of directed energy technology, is that they are using ultrasound energy, as I have used lead, iron and aluminum for shielding but with no effect, but fuzzy materials tend to diminish the energy. In addition, the energy seems to be focused on the surface of the target, that is to say the fuzzy shielding inches away from the target surface do not provide protection. Aaron Alexis and Richard Weston Jr each claimed to be victims of directed energy, but the news reports discredit those claims as they also were reported to hear voices. I point out three flaws 1)that sleep deprivation from these devices can cause outward symptoms of mental illness, 2) sound communication can be modulated by this technology, 3) there is no rule that prohibits these devices to be covertly used on the mentally ill.  My guess is that pulsed microwaves or pulsed lasers are being used to generate ultrasound vibrations in distant targets. 
Another point is that even though the crowd control devices have been in field testing since at least 1998, they have not been marketed in public view to police departments despite clearly crowd control problems. I say this in an effort to make the public aware of this covert activity, please do not delete it.  — Preceding unsigned comment added by 50.104.194.10 (talk) 06:24, 29 May 2015 (UTC)

thread_title: Crowd control weapons, covert uses

message: There are some problems with the sources. The "Plastics Technology" and "The Welding Institute" links are dead. Some of the sources are magazine articles or from industry sources.
Also, I think the References section should not have Notes and Bibliography subsections. Some notes are not included in the bibliography and vice versa.--Missstarsineyes (talk) 03:53, 22 January 2018 (UTC)
replies: text: Without looking closely, and without more details on what to look for, I don't think there are any problems. The breakdown of Notes and Bibliography is not as common as other approaches, but superior in many ways. Dead links themselves aren't a problem, though they should be replaced with working links if possible (from the same organizations, from archives, or legal copies hosted elsewhere). --Ronz (talk) 18:16, 22 January 2018 (UTC)
