    摘要： A collet chucking assembly for gripping bar stock having a tubular spindle through which bar stock may be fed, separate front and rear chuck sleeves, separate front and rear collets, and a chuck nut that is screw tightened on the threaded end of the spindle. The rear chuck sleeve is slidably positioned within the threaded end of the spindle and the forward end of its bore tapered to mate with a tapered surface of the rear collet. A front chuck sleeve is slidably positioned within the spindle, one end engaging the rear collet, the forward end being tapered to mate with a tapered surface of the front collet. A chuck nut holds the collets within the spindle.

    摘要： The disclosure of the invention is a diaphragm-type pneumatic logic element having two formed plates mounted in facing relation with complementary pairs of chamber recesses and interconnecting channel recesses formed in the facing surfaces of said plates, and a flexible diaphragm bonded to the facing surface of each plate excepting only a narrow area surrounding each chamber recess which is left unbonded. The improvement consists of a diaphragm support interposed between the diaphragms. The diaphragm support is a thin but relatively stiff sheet of material, preferably beryllium copper in the order of 0.002 inches thick, which is formed with apertures which register with and are of slightly larger diameter than the chamber recesses, but of less diameter than the usual unbonded area between the diaphragm and plate surrounding each chamber recess.
