A process for solvent dewaxing a waxy oil feed to produce a lubricating oil by contacting a warm waxy oil feed in counter-current with a cold oil/solvent filtrate stream through a selectively permeable membrane to transfer cold solvent through the membrane to the feed and simultaneously cool the feed, dilute it with solvent and separate solvent from the cold oil/solvent filtrate stream. The cooled...

A chair with a fabric sling backrest and seat which suspend under tension when the chair is expanded from stretcher and support tubes. The chair collapses by unlocking studs-mounted on the chair's stretcher tubes-from receiver slots, and rotating the stretcher tubes ninety degrees into one plane. The back support tubes also pivot down into the same plane. The chair then easily folds into a compact...

An electrode carrying catheter (10) of high flexibility along substantially its entire length includes an elongate, flexible tube (12) defining a proximal end (14), a distal end (16), and an electrically insulative outer tubular surface (20) intermediate the ends (14) and (16). At least one electrode (30), formed of a thin, flexible layer of an electrically conductive ink, is disposed on the tube ...
