    摘要: A method for converting methane to higher hydrocarbon products and coproduct water wherein a gas comprising methane and a gaseous oxidant are contacted with a nonacidic catalyst at temperatures within the range of about 700.degree. to 1200.degree. C. in the presence of a halogen promoter, the contacting being conducted in the substantial absence of alkali metals or compounds thereof.

    摘要: Apparatus for pressure testing fluid transmission pipelines comprising spaced apart annular inflatable seal members supported by support members which are interconnected by an elongated flexible tube to define an annular space which may be pressurized to pressure test a section of pipe between the seal members. The tubular member defines a flow passage for pipeline fluid during operation of the apparatus. A fluid motor is disposed in the passage and drivably connected to a hydraulic pump which receives fluid from the pipeline to pressurize the seal members and the annular space. The pump may be remotely controlled by radio control receiver-transmitter apparatus to operate the pressure testing apparatus and to monitor pressures in the seal members and the test space. The pump and control members may be disposed in a housing which is mounted adjacent one end of the apparatus. The apparatus is propelled through a pipeline by pressure fluid in the line.

    摘要: The weight of a transport vehicle and the actuator of an impact type seismic source carried thereby is partially transferred by means of hydraulic lift cylinders to a freely movable earth contacting baseplate positioned beneath the actuator. In operation a mass is propelled by the actuator along a prescribed slant path to strike the baseplate. Shear strain is induced in elastomeric pads sandwiched between the hydraulic lift cylinders and the baseplate if the baseplate shifts sideways under such a slanting blow. The pads then exert a force to restore the vehicle and the actuator to a correct perpendicular alignment over the baseplate. Upper and lower position locator means fixed respectively to the hydraulic lift cylinders and to the baseplate interface with the elastomeric pads and fit slidably within each other so as to transmit vertical force from vehicle to baseplate. Intentional slight misalignment between the upper and lower locator means induces further restorative strain in the elastomeric pads as the locator means engage with each other.

    摘要: An improved lubricant and coolant removal system for a roll stand includes suction boxes surrounding the sheet formed by the roll stand and a series of pipes connecting the suction boxes to various coolant traps. Special doctor blades and air knives remove coolant from the rolls. An enclosing shroud prevents coolant overspray and mist from escaping.

    摘要: A method for rendering stresses and strains in a well casing more uniform throughout the length of the casing in a permafrost zone, the permafrost adjacent the casing being at least partially thawed, wherein the permafrost is allowed to refreeze at least in part until the well casing can physically move relative to the thawed soil thereby rendering such stresses and strains more uniform throughout the casing length.
