Abstract: A two part encapsulated cementing system is mixed downhole in a method of plugging an abandoned well. Using this two part system, one of the components is first placed in the well at the desired plugging depth. Next, the other component is placed in the well above the first placed component. Densities of the components have been selected such that the density of the second placed component is sufficiently higher then the density of the first placed component to facilitate gravity mixing of the two components as the second placed component moves through the first placed component and in the process activation occurs.

Abstract: A method of remediation of a well is provided utilizing a cement and cement activator plugging composition, in which one of the components is first placed in the well at the desired remediation depth. Next, the other component is placed in the well above the first placed component. Densities of the components have been selected such that the density of the second placed component is sufficiently higher then the density of the first placed component to facilitate gravity mixing of the two components as the second placed component moves through the first placed component and in the process activation occurs.

Abstract: An apparatus and method for aligning a housing such as a flywheel housing with a crankshaft or other rotating member. The apparatus includes a main shaft and a mount by which the main shaft is mounted to the center axis of a member rotating in a housing. A sleeve is received upon and rotates relative to the main shaft and is provided with a mount for a dial indicator. The dial indicator is positioned so that any misalignment between the rotating member and the housing is output by the dial indicator as the sleeve is rotated relative to the housing. Depending upon the output of the dial indicator, the position of the housing is changed relative to the rotating member to align the center axis of the rotating member with the center axis of the housing.

Abstract: A dual diameter centralizing sub for maintaining stand-off and/or centralizing a tubular member inside a larger diameter tubular member, for instance, in a wellbore. The centralizer is provided with bow springs that compress into grooves between radially outwardly-extending vanes that are spaced around the outer diameter of the sub when compressive force is applied to the bow springs. The vanes extend radially outwardly far enough that the effective diameter of the sub in the area of the vanes is greater than the diameter of the sub and/or the tubing to which it is mounted to provide stand-off even under conditions in which the bow springs are fully compressed.

Abstract: There is disclosed a vacuum storage and dispensing container for use with perishable items, particularly food products, and more particularly for use with roasted whole-bean coffee in any retailing application, to extend the shelf life of the perishable item for several months. The invention comprises a storage and dispensing container having a cylinder with a top end and a bottom end. An upper enclosure is attached to the top end and a lower enclosure to the bottom end. There is provided a system for releasing and creating a vacuum in the cylinder, upper enclosure, and lower enclosure for maintaining freshness of the perishable item. In another aspect, there is disclosed a merchandising unit for storing and dispensing perishables comprising a plurality of storage and dispensing containers. Each container includes a cylinder having a top end and a bottom end. An air-tight upper enclosure is attached to the top end and an air-tight lower enclosure to the bottom end.

Abstract: A method and apparatus for sampling and analyzing gas. In particular landfill gas, which consists primarily of methane and contains volatile organic components, is passed through a quantity of liquid tetraglyme to cause the volatile organic components to be absorbed in the tetraglyme. The tetraglyme containing the absorbed volatile organic components, is then disposed in a sealed container and transported to a laboratory testing facility. At the testing facility, at least a portion of the tetraglyme is withdrawn from the container, dispersed in water, and subjected to a gas chromatography/mass spectrometry procedure to analyze the volatile organic components.

Abstract: Disclosed is a mobile vibratory abrasive cleaning apparatus that includes a flatbed having wheels upon which are mounted the other components of the apparatus which include a cleaning tank, a vibrator for vibrating the tank, a loop system for circulating the abrasive cleaner through the tank, control panel and power generator supplying electricity for running the apparatus. The loop system for circulating abrasive cleaner through the tank includes sprayers in the tank, an abrasive cleaner surge tank, filter system and drain system. In operation, the abrasive cleaner is pumped from the cleaner surge tank to the sprayers in the cleaning tank, and after contacting the articles to be cleaned, the abrasive cleaner drains from the cleaning tank and is pumped back to the cleaner surge tank. Contaminants are removed via a filter provided in the surge tank and/or the drain system.

Abstract: A method for removing volatile organics from landfill gas, in which the landfill gas, which consists primarily of methane and contains volatile organic components, is passed through a quantity of liquid tetraglyme to cause the volatile organic components to be absorbed in the tetraglyme.

Abstract: A mud saver valve has been developed for controlling flow of drilling fluid through an upper portion of a drill string, the mud saver valve in one aspect has a tubular housing, a ball closure rotatably disposed within the tubular housing, the ball closure having a body, a flow channel therethrough, a first body side and a second body side opposite the first body side, a first lug projecting from the first body side and a second lug projecting from the second body side, a sleeve assembly movably disposed within the tubular housing, the sleeve assembly having a first and a second actuator e.g, dogs, to engage corresponding first and second lugs of the ball closure to open or close the ball closure in response to fluid pressure conditions as well as engagement and disengagement of the tubular housing with the drill pipe against the force of a coil spring disposed within the tubular housing.

Abstract: In combination, a generally conical structure for collecting air and providing a confined space for solar heating of such air, connected, at the upper end of the conical structure, with a vertically placed electric generator through which the solar-heated air passes. The combination utilizes the principle that the heated air expands and becomes lighter, causing it to be displaced by the cooler, atmospheric air at the bottom of the air collecting structure, creating an upward flow of the heated air through the electric generator. The generator is unique for the purpose in that the generator rotor and turbine turn in concert and are a single unit.

Abstract: A safety cover for a gas outlet comprising a mounting plate for securement to a gas outlet pipe and a cover hinged to the plate whereby the cover may be positioned over the outlet and pivotally moved out of the way to permit access to the gas outlet. Typically, the cover is color-coded to identify the source of gas available at cite of use.

Abstract: Gaseous streams containing carbonyl compounds are reduced in carbonyl compounds by reacting a vapor phase with catalyst comprising as the major cation portion at least two metals of Periodic Table Groups 1b, 2b, 4b, 6b, 7b and 8. Reactor effluent from oxidative dehydrogenation reaction to produce butadiene-1,3 is reacted with iron oxide - copper chromite on AMC catalyst to remove carbonyl compounds.
