    摘要: A method for making a hydropneumatic accumulator with a replaceable bladder for an active vehicle suspension comprising the steps chemically treating a resilient single layer bladder with a gas to provide imperviousness of a compressible gas through the bladder, bonding a spherical bumper to a closed end of the bladder, engaging an inward facing seal portion extending around an "open mouth" portion of the bladder with an external groove extending around a cylindrical cap to close off the "open mouth" portion, slideably mounting the cap and said bladder in the interior of an accumulator housing to divide the housing into a first sealed chamber for a hydraulic liquid and a second sealed chamber for a compressible gas; and engaging a detachable ring with a groove in the interior of the accumulator housing to retain the cover and the bladder in the housing.

    摘要: A method of making and an amperometric electrode are provided. An electrode carbon ink is applied to a polymer substrate to form a working electrode. The substrate carrying the working electrode is placed in a gas plasma cleaner, such as an oxygen or nitrogen plasma, to clean the working electrode. A high radio frequency signal excites the gas plasma for a short exposure time in a range between 10 seconds and 30 seconds. Then a reagent layer is deposited to the plasma treated working electrode.

    摘要: The present invention relates to a number of innovative electrophilic substitution reactions involving 2,5-dithienylpyrrole (2,5-DTP). More specifically, these reactions are used in the synthesis of monomers for preparing functionalized conducting organic polymers.The electrophilic substitution reactions in this invention are accomplished under conditions not requiring the use of N-1 pyrrole blocking groups to direction reaction at the pyrrole C-3 position. This is because the steric bulk of the 2,5-dithienyl groups prevent N-acylation and therefore direct reactions with electrophiles at the pyrrole C-3 position.The reaction conditions chosen have also demonstrated a greater regioselectively towards functionalization at the pyrrole 3-position than the basic reaction conditions suggested in the prior art. This result may be explained by an activation of the pyrrole 3-position towards electrophilic substitution. This is attributed to an electron donating resonance contribution of the 2,5 thienyl groups.Other advantageous reaction conditions have been discovered which direct electrophilic substitution preferentially at the pyrrole or thiophene groups depending upon the amount of acidic catalyst.
