    摘要: A scavenger for purifying inert gas mixtures to remove Lewis acid and oxidant impurities therefrom, comprising (i) an inert inorganic support, and (ii) an active scavenging species on the support, formed by deposition thereon of an organometallic precursor and pyrolysis thereof at a selected elevated temperature. The organometallic precursor is an alkyl metal compound comprising a metal of Group IA, IIA, and/or IIIA, wherein the pyrolysis temperature may range from about 150.degree. C. to about 250.degree. C., depending on the specific alkyl metal compound employed as the precursor. Also disclosed are: a corresponding method of making the scavenger; a process for purifying inert gases by contacting same with the scavenger; and a vessel containing a bed of the scavenger, useful as an apparatus for purifying inert gases.

    摘要: A high flash point cycloolefin composition, including at least 50% by weight dicyclopentadiene, the composition having a flash point of greater than 100.degree. F. and a viscosity of from about 3 cps to about 3000 cps at about 70.degree. F. and about 1 atmosphere pressure. The cycloolefin composition is used in a method of preparation of cycloolefin for polymerization by metathesis catalysis to form a substantially crosslinked thermoset polymer by: distilling the cycloolefin to form distilled cycloolefin, and contacting the distilled cycloolefin and an adsorbant.

    摘要: An electrochemical drive circuitry and method, such as may be employed in electroplating bath chemical monitoring. A microcontroller can be utilized to selectively apply galvanostatic or potentiostatic conditions on the electrochemical cell, for measurement of response of the electrochemical cell to such conditions, with the microcontroller arranged to generate an offset potential to control potential across the electrochemical cell within a range of potential accommodated by a unipolar power supply, and/or a CMOS analog switch can be employed in combination with individual digital-to-analog converters for each of the current-controlled and potential-controlled conditions, to provide high-speed, dual mode operating capability.
