Abstract: A tool mount for use with a sleever bar includes a locking handle moveable between a secured position and a locked position. The tool mount further includes a positioning wheel aligned adjacent to the locking handle. The positioning wheel may be configured to engage the locking handle when the locking handle is in the locked position, and rotate freely relative to the locking handle when the locking handle is in the secured position. The tool mount further includes a tool holder coupled to the positioning wheel and configured to receive the sleever bar, wherein the tool holder rotates freely with the positioning wheel when the locking handle is in the secured position.

Abstract: A chalk line reel system includes a chalk cartridge having a cartridge housing including a chalk compartment at least partially filled with chalk and a chalk dispensing opening to the chalk compartment. The chalk cartridge has a frangible seal closing the chalk dispensing opening. The chalk line reel system includes a chalk line housing having an interior space, a mount structure for releasably mounting the chalk cartridge, and a seal breaking structure configured to break the frangible seal to allow chalk to be dispensed from the chalk compartment into the interior space with the chalk cartridge engaged in the mount structure. The chalk line reel system includes a reel mounted to the housing for rotation relative to the housing about a reel axis, and a chalk line wound around the reel and engageable with chalk contained in the interior space.

Abstract: A vehicle behavior system comprises a computer system, an observation processor, and neural networks. The observation processor and the neural networks are located in the computer system. The observation processor is configured to receive observations for a vehicle system. The observations are for a current time. The observation processor is configured to extract features from the observations. The neural networks are configured to receive the features extracted from the observations and estimate a behavior for the vehicle system for time steps in response to receiving features extracted from the observations processed by the observation processor. Each of the neural networks is trained to estimate the behavior for the vehicle system for a different time step in the time steps.

Abstract: A method and apparatus for containing one or more shaped charges in a single plane, using a shaped charge housing containing a cluster of one or more shaped charges. The cluster contains with the apex ends facing each other, arrayed about the center axis of a gun body, and detonated from a single initiator located in the middle of the cluster of the one or more shaped charges. The shaped charge housing can be one of many shaped charge housings coupled together to perforate in a plurality of single planes.

Abstract: Methods for providing wellbores for electromagnetic heating of a hydrocarbon formation positioned below a ground surface and apparatus thereof are provided. The apparatus includes two or more wellbore casings positioned within two or more wellbores. The two or more wellbores extend from a proximal end at the ground surface to a distal end at the underground hydrocarbon formation. Each of the two or more wellbore casings have a proximal portion and a distal portion. The two or more wellbores are in proximity to one another at a junction. The apparatus also includes a first electrical connection between the proximal portions of the two or more wellbore casings for grounding the two or more wellbore casings and a second electrical connection between the distal portions of the two or more wellbore casings. The second electrical connection is located at the junction and provides a short circuit that reduces current traveling on the two or more wellbore casings to the ground surface.

Abstract: A method and apparatus for attenuating a shaped charge explosive by layering shock attenuation materials in between an internal liner and external shell to form a shaped charge case.

Abstract: A shaped charge having a liner with three frustoconical segments and a bottom portion configured to provide consistent perforating holes over a range of distances from the shaped charge.

Abstract: A method and apparatus for perforating a wellbore by firing one or more projectiles into a casing and formation using a single source of energy.

Abstract: The device disclosed herein is suitable for simultaneously cleaning opposing surfaces of the Juliette-style balcony windows. The device is constructed to have dimension that, when in a compact form, it can be inserted into the gap formed between a balcony or patio door and a balcony facade and hand rail. A pair of cleaning heads, situated on opposite sides of an expandable or inflatable member, can be positioned to contact the opposing glass surfaces by actuation of the expandable or inflatable member from the compact to the expanded position. Subsequent manual movement of the opposing pair of cleaning heads, in combination with the application of water and optional cleaning products, resulting in the cleaning of the opposing surfaces of the Juliette balcony window.

Abstract: A tubing string, such as a coiled tubing or jointed tubing string, has an agitator mounted within an interior of the tubing string at an intermediate position between an uphole end and a downhole end of the tubing string. A tubing agitator is structured to be installed within a tubing string. A method includes: forming or installing a seat within an interior of a tubing string at an intermediate position between an uphole end and a downhole end of the tubing string; and conveying an agitator through the interior of the tubing string until the agitator contacts the seat. A hammer drift tool is also described.

Abstract: A firearm accessory is operable in two modes. A first mode in which the firearm accessory is coupled, at least indirectly, to a firearm to define a foregrip. In the first mode, a blade on the accessory is in a sheathed position. A second mode in which the firearm is disconnected from the firearm to define a knife. In the second mode, the blade is in an extended position. In each mode and position, the tip of the blade is vertically above the upper end of the grip body. The firearm accessory has prongs that connect the grip body to an attachment mechanism or coupler. Within the coupler are flexible liner locks that have sloped protrusions that engage recess in the blade to lock the blade in the extend position. The liner locks may be flexibly unlocked by depressing a button carried by the grip body.
