    automatic swinging door

    I assume you are thinking of a patent. Be careful as there are crooked patent agencies out there. Start with the us government patent office. Do a web rearch for patent office and you will get a lot of (488529) references. wzkb <They are just Jealous that the Voices don't talk to Them>

    Seek advise on an NC machine to tak

    Seek advise on an NC machine to take 3-D .STL files and produce an object whose visible surface matches that of the object. Desired output max size: H=45 cm, L=30 cm, W=30 cm (smaller could be OK to begin). Should be capable of thin (i.e. around 1-2 mm). Example: coffee cup from wood or a cat's...

    3-D machines

    Seek advise on an NC machine to take 3-D CAD output and produce an object whose visible surface matches that of the CAD object. Desired output max size: h = 45 cm, w = 30 cm (smaller could be OK to begin). Should be capable of thin (i.e. around 1-2 mm). Example: coffee cup made from wood As an...

    i need tips on circuits in basic telephone system

    The best allin one place source is &quot;Transmission Systems for Communications&quot; by Bell Telephone Labs. I have the fifth edition (1982) and have used it extensively. Try to fine it in the library as it's out of print. wzkb <They are just Jealous that the Voices don't talk to Them>

    Who knows of useful Chemical Eng spreadsheet or Mathcad downloads?

    Unless there is something on the MathSoft site I cannot help much. I have a copy of some work - &quot;Vortex Method Simulation of Turbulent Flow&quot;&nbsp;&nbsp;by Peter S. Bernard that I could send you if you will contact me directly.&nbsp;&nbsp;I found it on the net.<br><br>Summary:This...

    multivibrator, A-STABILE

    Use capacitor cross-coupled transistors, the CD4528 (or123, 221, 423) or build one from schmidt triggers (HC14s).<br><br>Look im most circuit design texts for a detailed amalysis of the transistor ckt.<br><br>You can also look at the LM555 timer chip.&nbsp;&nbsp;National had a great app. book on...
