    Sensing Moist objects

    Thanks for the suggestions. I have been checking the capacitive sensor market, but most of those are used as proximity sensors, and need to be very close, within a few millimeters. Due to some movement issues, we can't be that close, we need to be at least an inch or two away from the objects...

    Sensing Moist objects

    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...

    Structural Insulated Panels

    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...

    Air classifiers/Particle Separators

    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...

    Engineering Standards

    You might want to check programs like Workflow that help organize and track engineering documents. Talk to the people at AutoCAD, I think they will have plenty of suggestions.

    Sustainable Chemistry and Agriculture

    How interesting. Drip irrigation is the only exception you cite, but the very material drip tubing is made from is a plastic. This is not only the product of chemistry, but it is a non biodegradable material (this should change soon with the new plastics coming from corn).  I believe...

    lightweight concrete

    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>

    Pneumatic Transport

    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...

    Vibration Analysis

    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...

    Size Classification of Granular Materials

    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...

    to learn programming with FEA and CAD

    Anyone have any knowledge or experience with a program called ALGOR? They claim to do surface analysis, including FEA.

    Injection of fertilizer and insecticides into irrigation systems

    MikeVV,<br> Yes, there are many off the shelf injector units like this available through greenhouse and hort suppliers, as well as some companies that sell animal medications which are put in the water. They range greatly in price and style, depending on the flow rates and accuracy you need...
