    摘要: A novel process effective for the removal of organic sulfur compounds, organic nitrogen compounds and light olefins from liquid hydrocarbons is disclosed. The process more specifically addresses the removal of these contaminants from aromatic compounds including benzene and toluene and from naphtha. The liquid hydrocarbons are contacted with a blend of at least one metal oxide and an acidic zeolite. Preferably, the metal oxide comprises nickel oxide and molybdenum oxide and the acidic zeolite is acidic stabilized zeolite Y. This blend has a significant capacity for adsorption of impurities and can be regenerated by oxidative treatment.

    摘要: In a system for locating the position of a transmitter, a platform containing an antenna is moved through a measurement path. The frequency received by the antenna is measured at measurement points distributed along a measurement path. The frequency is measured by cross correlating coherent pulses of the received frequency signal. An inertial navigation system on the platform indicates the position of the measurement path. A computer determines estimated locations by non-linear least squares convergence starting from trial locations. The non-linear least squares convergence is based on the frequency equation for the received frequency ##EQU1## in which f.sub.0, is the transmitter frequency, V is the antenna velocity and r is the range of the transmitter. The computer evaluates a cost function derived from the frequency equation, for each location estimated by the non-linear least squares convergence and selects the estimated location with the lowest cost function as the best solution.

    摘要: In the process flow scheme for chromatographically separating para-xylene from C.sub.8 isomers containing substantial amounts of C.sub.9 aromatic hydrocarbon impurities with BaX or KY zeolite adsorbent and heavy desorbents, e.g., tetralin and diethyltoluene, a bottoms stream from the extract fractionation column containing desorbent is recycled to the separation unit and a sidecut stream, containing C.sub.9 aromatic hydrocarbon impurities and a minor amount of the desorbent from the raffinate stream, is directed to the raffinate fractionation column, thereby removing C.sub.9 aromatic hydrocarbons from the desorbent before recycling the desorbent to the separation unit, and preventing C.sub.9 aromatics from building up in the desorbent input. A fractionator for the extract column bottoms stream is eliminated, lowering capital costs, and energy requirements for the raffinate column are reduced.

    摘要: A dual function cart convertible between a wheelbarrow-type load transporter and a vehicle towed cart. The cart comprises a frame supporting a load carrying tube, the frame including a transversing extending axle having relatively large diameter spoked wheels journaled for rotation on opposed ends of the axle. Pivotally secured to the frame is a handle assembly in the form of a rectangular loop which, when latched by a removable rod in a first position orients the handle in an upright plane where the vehicle can be operated as a wheelbarrow. Alternatively, the removable rod may be used to latch the handle in a generally horizontal plane at an elevation facilitating connection thereof by a clevis to a hitch on a towing vehicle. The cart also includes an auxiliary side member which may be secured to the tub for increasing the effective load-carrying volume of the tub.
