We want to monitor an "assembly line" situation where we have solid, porous objects coming down the line, somewhat equally spaced, running at about 4 feet/second. Any optical sensor can watch for a missing piece, but some of the pieces did not get wet like they should. Anyone aware of...

I've been reading about SIPS (structural insulated panels), and they seem very impressive for use in walls, floors and roofs. Has anyone got any good or bad experience with these to share? Different foams are used for the core, most use OSB for the exterior, although some now come with sheet...

We are interested in air classifiers. Units referred to as "aspirators" are usually designed to take dust and fines out of larger particles. They often rely on turbulance to stir the material and the waste material is channeled through a fan. This is not the right approach for us. We...

I've heard about some lightweight concretes used in Europe for years (air injected?) that are now being used in the USA. Does anyone have the background story on this material, what its limits and assets are, and who is working with it or selling it in the US?<br>

I've been reading about dilute and dense phase pneumatic transport of granular materials and powders. I'm trying to find someone who is familiar with saltation and particle segregation issues; often these are hydraulics people. Does anyone have any leads or referrals? Perhaps I should be posting...

Anyone have any suggestions for someone who wants to learn about vibration analysis from zip? I've been looking over some books on the topic and talking with equipment vendors, but anyone have any ideas beyond that or have any favorites that should be on my to-check list?<br> thx <A...

We work with granular materials quite a bit, in the 5 to 10mm range. Often we do size classification using screens with round holes. We are looking to improve this system, but also looking at alternatives, like air classification, optical methods, etc. Anyone with similar interests or...

Hi,<br> I'm looking for information, products and services related to geodesic domes, spaceframes and shell structures. These can be journals, websites, books, technical reports, engineers/architechs, etc, e.g. anything you this is helpful. Any leads appreciated.<br> thx <A...
