The part in the photo looked very familiar. I went to my "secondary" desk behind me and picked up the part. The photo looks identical except mine has a hole for safety wire. The inner part is made up of two 180 degree parts, each with a "thread" cut on the inside and the clamp holds both parts together. It is used on a Gulfstream G1 turboprop 40kw auxillary power unit. The plane itself was built in 1958! This mechanism was designed so one mechanic could hold the heavy generator in place while another attached the "nut" to remove the loading. The strap holds it all in place and is safety wired to prevent it from coming apart unexpectedly in the air, always bad juju! It was no doubt an expensive part. It appears that auto manufacturers have found a cheaper was to fabricate them, but it is most certainly not new.
Spiralok has been around for a long time, but engineering folks need to be reminded or newly presented with this product's capability, every so often. I still have a Spirolok demonstration assembly on my desk. It reminds me of this potential solution, every time I glance at it. Many coworkers have picked it up and examined it, over the years.
I believe you missed the point they are trying to make. I would blame the author for not showing an illustration of the thread form. It is not the V-Band Clamp that they are talking about as new. It is the thread form that they refer to as Spiralock. By the way, this thread form is not new either. Someone just seem to be promoting it for a new found application.
Way back (late 1960's) when I worked summers as a part-time janitor for a school district, they had cleaning supplies deliverd in fibre drums (sweeping compound, etc). The lids on these drums were retained with exactly the same form device with the band in a U or V form to lock the lid to the top rim of the drum and with either a draw screw or over-center-snap link to draw thins tight.
OK this is a high temp alloy as needed by the application, but this is not new.
I agree Naperlou. With all of the attention on the innovation going into EVs and hybrids, I think some of the innovation on traditional gas engines is getting overlooked. In the long run, improved internal combustion engines may save more gas than electric vehicles.
Rob, that's just what I have been saying! It is interesting that in Formula 1 racing the turbocharged engines are limited to 1.5L as oppossed to the naturally aspirated engines at 3.0L. Just an aside, these engines put out over 700HP. We can get the horsepower we need to drive our vehicles with less fuel, but it will take lots of engineering to make them as reliable as the current engines. This is just one good example of an engineering "detail" that is critical to success.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
