Air Cylinders, Fittings and Solenoids Valves

The Story: I am a member of the Robot Group in Austin Texas, and recently they received a series of "test beds" that were retired from one of the semiconductor plants here in Austin. These were disassembled into various components. I went through and found some bits and pieces that I thought might be useful for my haunt, but I wanted to get some feedback from other list members as to the purpose of some of these parts. We have quite a few boxes full of parts like this and this is only a small cross section. Oh, and the two 14" stroke Bimba's did not come with it, they were purchased from MPJA recently. I just put them in the picture to give an idea of scale. Each thumbnail is "clickable" to get a much higher resolution picture. :)
