Title: Metal oxide films
IPC: C23C14/00
Filed: 1971-05-19
Abstract: In a method of depositing a transparent electrically conductive metal oxide coating by reactive sputtering onto the surface of a substrate, the substrate is supported, in spaced relationship with a cathode which is to be sputtered, in a vacuum chamber containing an atmosphere comprising an inert gas and a controlled oxygen concentration at a selected total pressure. The substrate is heated prior to sputtering to a selected elevated temperature, and reactive sputtering is caused by applying a selected negative potential relative to the substrate. The oxygen in the atmosphere is provided and maintained at a selected concentration, and the heating of said substrate is controlled during sputtering to maintain the substrate temperature substantially constant at the selected temperature during substrate heating caused by sputtering. The selected values of the oxygen concentration substrate temperature, vacuum chamber pressure, and cathode potential are so chosen that the deposited coating is haze-free, and its specific electrical resistivity lies at or close to the minimum of the curve which is obtained by plotting specific electrical resistivity against oxygen concentration while maintaining the substrate temperature, vacuum chamber pressure and cathode potential all constant at the selected values. Glass articles with stable, transparent and haze-free coatings having acceptable resistance are produced by the method.

Patent ES-451790-A1 (ES)
Title: Process for separating normal and isoparaffins
IPC: C07C1/00
Filed: 1976-09-23
Abstract: An improved process for separating normal paraffins from a feed stream containing a mixture of normal paraffins, isoparaffins and aromatic hydrocarbons to produce a normal paraffin product stream having a reduced concentration of contaminant aromatic hydrocarbons. The general process comprises the steps of contacting the feed stream with an adsorbent comprising a crystalline aluminosilicate wherein normal paraffins are adsorbed within the pores of the adsorbent and contaminant aromatics are adsorbed on the surface of the adsorbent and subsequently contacting the adsorbent with a desorbent material to remove both adsorbed normal paraffins and contaminant aromatics. The improvement resides in using a two-stage desorption step in which a first desorbent material contacts the adsorbent and removes surface-adsorbed aromatic contaminants and then a second desorbent material contacts the adsorbent to remove normal paraffins adsorbed within the pores of the adsorbent.
