Abstract: An integrated process for the conversion of methanol to high octane gasoline and distillate. Methanol is converted to olefins in the presence of zeolite type catalyst. C.sub.4 and C.sub.5 olefin fraction is converted to MTBE and TAME in the presence of excess methanol and acid etherification catalyst. Unreacted methanol and hydrocarbons are passed to an olefins to gasoline and distillate oligomerization unit in conjunction with C.sub.3, C.sub.6 and C.sub.7 olefins from the methanol to olefins unit whereby distillate and LPG products are produced. Gasoline products from the oligomerization unit are passed to the etherification unit whereby an ether-rich gasoline fraction is separated.

Abstract: An improved process for oligomerizing olefins is provided in which olefin feed is contacted with phosphoric acid catalyst to form an olefin oligomerization product containing phosphorous-containing foulant precursors. The olefin oligomerization product is then contacted with a foulant adsorbent comprising at least one member selected from the group consisting of alumina, activated alumina and magnesium oxide in an amount and under conditions sufficient to effect removal of at least a portion of said foulant precursors. The treated olefin oligomerization product stream can then be passed to downstream recovery and process equipment with minimized fouling.

Abstract: A method is disclosed for reducing combustion chamber deposits in an internal combustion engine by the passage of an aqueous deadhering agent such as water to the combustion chamber at cold start conditions and permitting the engine to crank for a period of time until said deposits deadhere from the walls of the combustion chamber. The aqueous deadhering agent can be water or the same with a diluent, such as a lower alkyl ketone. This invention is applicable to combustion chamber deposits which have resulted from the use of an additive agent, such as an amine-urea type detergent additive in as low a concentration in gasoline fuel as 50 ppm.

Abstract: A method and apparatus are provided for distillation of hydrocarbon oil subject to coking threshold temperature limits. A hydrocarbon oil is heated to a first predetermined maximum temperature above which coking is likely to occur. The heated hydrocarbon oil is introduced into a first distillation zone, wherein the heated hydrocarbon oil is separated into a liquid portion and a vapor portion. The descending liquid portion is withdrawn from the bottom region of the first distillation zone, and the withdrawn liquid is reheated to a second predetermined maximum temperature, above which coking is likely to occur in the return heater line. Finally, the heated withdrawn liquid is returned to a second distillation zone, wherein a second separation occurs to achieve increased valuable products recovery. A divider arrangement maintains the first and second distillation zones physically separate from each other.

Abstract: A method for analyzing the biomechanical behavior of the cardiac muscle and for diagnosing pathological conditions of the heart. The apparatus measures and records the rise and fall of intra-ventricular isovolumetric pressure monitored by a transducer installed at the tip of a cardiac catheter. The pressure versus time recordings during both the systolic and diastolic phases are mathematically analyzed, and two parameters indicative of the biomechanical conditions of the muscle are derived. The parameters are then plotted against each other on a map in which diagnostic zones of various normal and pathological heart conditions are delineated. The cardiac catheter is fitted with a balloon inflation valve used to close the aortic port during a single heartbeat in order to override the aortic valve and maintain the isovolumetric condition during contraction and relaxation of the cardiac muscle organ.
