    Abstract: A lamp clamp uses a portion of the lamp as a moveable clamping jaw. This portion is screw-threaded into a threaded aperture of one of the arms of a C-shaped member. The other arm of the C-shaped member includes an object-engaging portion which further includes two pressure pads separated by a dished portion. The C-shaped member includes a coextensive flange around the inner periphery of the "C". The flange assists in stabilizing the clamp against the object, such as, the side edge of a worktable. The end of the moveable portion is attached to a swivel head which is pivotably engageable with the object in several orientations. The arrangement is especially useful when it is desired to mount a flashlight having a flexible stem (such as the Black & Decker.RTM. SnakeLight.TM. flashlight). The moveable clamping jaw defines a cylindrical tube into which is slideably mounted the graspable portion of the flashlight. Inasmuch as the graspable portion includes a tab member, an elongated groove is formed in the lamp-receiving receptacle moveable clamping jaw so that the tab may slideably and snugly engage the groove, and, accordingly, maintain a specific orientation relative to the worksurface. All of the component parts are made of plastic.

    Abstract: The present method produces treated water from a direct steam generator. The method begins by injecting water into a direct steam generator. The injected water is then vaporized with the direct steam generator to produce steam and an effluent stream. The combustible water impurities in the water are then combusted inside a chamber in the direct steam generator and the solid particles are removed from the effluent stream to produce a treated stream.

    Abstract: A method for preheating a formation prior to beginning steam assisted gravity drainage production. The method proceeds by forming a steam assisted gravity drainage production well pair within a formation. A preheating stage is then begun by injecting an activator into the formation. The preheating stage is then accomplished by exciting the activator with radio frequencies. This is followed by beginning the steam assisted gravity drainage operation.

    Abstract: Methods and apparatus relate to producing hydrocarbons. Injecting a fluid mixture of steam and carbon dioxide into a hydrocarbon bearing formation facilitates recovery of the hydrocarbons. Further, limiting amounts of non-condensable gases in the mixture may promote dissolving of the carbon dioxide into the hydrocarbons upon contact of the mixture with the hydrocarbons.

    Abstract: A method relates to improving production rate and recovery of heavy oil or bitumen and reducing heat loss to over and under burden in a steam-assisted production process. The method includes strategically injecting recycled carbon dioxide into the reservoir between production wells. The heat insulation and solvent effects provided by carbon dioxide dissolved in the oil phase facilitate the desired improvement on oil recovery, and simultaneously sequester the CO2 back into the reservoir.

    Abstract: A method for reducing thermal loss in a formation comprising two zone capable of production. The method first begins drilling a pair of wells, comprising a first well and a second well in a formation having two production zones, wherein one production zone is a thief zone such that the first well and the second well are in fluid communication with the thief zone. A sealing agent is injected into the thief zone via a first well and produced from the second well. Either the first well or the second well is then capped to form a capped well and a uncapped well. An amount of activating agent is injected into the uncapped well to form in-situ a thermally restrictive substance inside the thief zone.

    Abstract: A reciprocating saw includes a carrier operable to cooperate with a motor to translate rotational movement of the motor into reciprocal linear actuation of a saw blade. A carrier is slidably disposed within the housing and includes a first portion adapted to receive a saw blade and a second portion having a slot therethrough. A rotatable element is fixed for rotation about an output shaft of the motor. A follower operably interconnects the carrier and the rotatable element wherein rotation of the rotatable element provides reciprocal linear motion of the carrier whereby the follower follows a reciprocal linear path within the slot.
