A simple and immediate in-line process, the Loctite AssureCure Systemincludes a new adhesive technology, a fiber optic light source, a light detector unit, and software that ties into the users existing PC or PLC.
naperlou - The manufacturer does mention a good correlation between their technique and FTIR. My consternation involved a fiber optic detection probe. I'm familiar with reflective FTIR techniques such as Attenuated Total Reflection (ATR) and Diffuse Reflection (DRIFTs), but I've only seen them used with sample stages and compartments having very known and calibrated sample geometries and optics. My suggestion of Raman was that it is a sister vibrational technique that often employs fiber optic probes as part of the detection optics. I don't know if Henkel is keeping the information close to the vest to simplify the technology or to keep it proprietary. I would love to learn more about it. -Bill =]
As a kid, mr orthodontist used a "new" adhesive to adhere my braces to my teeth. It was a quick procedure that avoided the long time spent in the chair. It worked well and was quick. This is something that could really help manufacturing items that need quick adhesion.
A visit to Henkel's AssureCure(TM) website contains a tab for Adhesives. It displays an image of Henkel LOCTITE 3924AC, which I assume contains the AC suffix for use with the AssureCure system. Their technology overview does not give specifics but it appears that it is a reflective or emissive technology that utilizes LEDs or Diode Lasers for illumination and fiber optics for collection. The displayed response signal is broad like an IR spectrum but from the configuration it looks like it may be based on RAMAN scattering. Changes to the RAMAN features exhibited between the cured/uncured adhesive would probably not be very large. Henkel provides a technical paper in which they mention a "specially developed algorithm" that calculates a direct correlation to the adhesive's degree of cure. I am definitely interested in learning more about their technology.
If Henkel isn't providing an adhesive along with this new testing system, it seems you might have identified some good partnership opportunities, Rob. It would seem that the light cure technology and test system would need to part of the same package/installation. I would hate to be one of those manufacturers that invested in the light cure technology only to find later on that the lightening source didn't curate the bond and I was stuck with a sizeable inventory of defective parts. Even the threat of such a scenario would quash any interest in the bonding technology, I would think.
More often than not, with the purchase of a sports car comes the sacrifice of any sort of utility. In other words, you can forget about a large trunk, extra seats for the kids, and more importantly driving in snowy (or inclement) weather. But what if there was a vehicle that offered the best of both worlds; great handling and practicality?
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
