The first basestock includes a Group II bright stock having a kinematic viscosity (ASTM D445, 40° C.) of from 250 mm2/s to 600 mm2/s, a kinematic viscosity (ASTM D445, 100° C.) of from 20 mm2/s to 70 mm2/s, a viscosity index (ASTM D2270) of from 80 to 120, and a pour point (ASTM D97) of from ?50° C. to ?20° C. The second basestock includes a polyalphaolefin (PAO) basestock having a kinematic viscosity (ASTM D445, 40° C.) of from 500 mm2/s to 3500 mm2/s, a kinematic viscosity (ASTM D445, 100° C.) of from 60 mm2/s to 300 mm2/s, a viscosity index (ASTM D2270) of from 150 to 250, and a pour point (ASTM D97) of from ?50° C. to ?20° C.

Abstract: A method for positioning a robotic device connector relative to a body access point in a patient, including: coupling a robotic device to a movable base located at a distal end of an adjustable arm; manipulating the adjustable arm to align a connector of the robotic device with an elongate surgical tool extending from a body access point; linearly moving the movable base coupled to the robotic device towards the body access point to position the connector of the robotic device in proximity to a proximal end of the elongate surgical tool; connecting the proximal end of the elongate surgical tool to the connector of the robotic device

Abstract: A system for extracting hydrogen from a gas containing methane, especially natural gas. Hydrocarbons contained in the gas are catalytically broken down in a reformer by steam in order to form hydrogen, carbon monoxide and carbon dioxide. Catalytic conversion of the obtained carbon monoxide with steam occurs in a downstream conversion step in order to form carbon monoxide and water. Carbon dioxide is removed from the converted gas flow by gas washing, and the washed hydrogen-rich gas flow is subsequently divided in a pressure-swing adsorption system into a product gas flow made of hydrogen and a waste gas flow. The waste gas flow is introduced with hydrogen, which is separated from the gas flow after gas washing, into a reformer which is essentially a carbon-free combustible gas, and is combusted there.

Abstract: The invention relates to a method for extracting hydrogen from a gas containing methane, especially natural gas. Hydrocarbons contained in the gas are catalytically broken down in a reformer (4) by steam in order to form hydrogen, carbon monoxide and carbon dioxide. Catalytic conversion of the obtained carbon monoxide with steam occurs in a downstream conversion step in order to form carbon monoxide and water. Carbon dioxide is removed from the converted gas flow (8) by gas washing (7), and the washed hydrogen-rich gas flow (10) is subsequently divided in a pressure-swing adsorption system (11) into a product gas flow (12) made of hydrogen and a waste gas flow (13). The waste gas flow (13) is introduced with hydrogen (14), which is separated from the gas flow (10) after gas washing, into a reformer (4) which is essentially a carbon-free combustible gas, and is combusted there. The invention also relates to a system for carrying out the method.
