Abstract: Among other things, there is disclosed a cylindrical device which is used to remove broken paintballs and other unwanted material from the barrel of a paintball marker or from other paintball equipment. Cylindrical cleaning devices currently known in the art are prone to separation and failure after use. The present disclosure includes structure such as barbs and/or openings, a snap-fit sleeve element, and/or one or more spacers to limit or prevent such failure. Structure for cleaning, including squeegee elements movable between an insertion configuration and a cleaning configuration, and other materials and configurations, are also disclosed.

Abstract: Among other things, there is shown embodiments of a feedgate for a paintball loader having vanes or paddles that permit supplying paintballs into the loader but limit or inhibit escape of paintballs from the loader through the supply hole. Embodiments can include a frame, which may be a single piece or multiple-piece structure, and an insert with flexible vanes or paddles. Embodiments can include a pivotable cap, and/or the insert can snap into the frame.

Abstract: Among other things, there is disclosed a cylindrical device which is used to remove broken paintballs and other unwanted material from the barrel of a paintball marker or from other paintball equipment. Cylindrical cleaning devices currently known in the art are prone to separation and failure after use. The present disclosure utilizes a series of barbs and/or openings such as through holes to prevent such failure.

Abstract: An oilfield tubular string 10, 60, 60A comprising a plurality of elongate joints having one or both ends threaded. The joints may be connected by a coupling including a generally sleeve shaped coupling body having a tapered upstream thread profile and a tapered downstream thread profile for threaded engagement with a mating profile of a respective joint. The coupling body includes a low stress flex groove 30 having a selected box thread runout bevel angle, and all transitions in the flex groove between surfaces are radiused to greater than 0.100 inches to minimize stress risers. A pin-in-box connection between tubular joints includes mating tapered threads 72, engagement of end shoulder 74, 76, 78, and 80, and a low stress flex groove 82. The present invention allows the elongate joints to be used as both a casing string and a drill string, thereby saving significant time and expense.

Abstract: A verification engine for verifying the design of a target system having a plurality of components interconnected by a plurality of target system buses is disclosed. The verification engine comprises a first hardware model and a second hardware model, both configured as a component and having a set of hardware model input/output pins. In addition, a first bus wrapper is connected to the first hardware model and a second bus wrapper is connected to the second hardware model. Further, a set of bus lines are each connected to the first bus wrapper and the second bus wrapper. Each bus wrapper also has switchable communicative circuitry that switchably communicatively connects each hardware model input/output pin to a bus line and has a control block controlling the switchable communicative circuitry. A system controller is connected to at least some of the bus lines and is adapted to transmit a sequence of time synchronization information to each bus wrapper control block by way of the bus lines.

Abstract: A threaded connection for improving fatigue resistance to cyclic loading is disclosed. The threaded connection basically comprises a pair of interlocking members having corresponding radially inner and radially outer spiral threads thereon, each spiral thread including a spiral compression flank and a spiral tension flank wherein at least one of the spiral compression flanks and spiral tension flanks on the inner spiral threads are in mating planar engagement with a corresponding spiral compression flank and spiral tension flank on the outer spiral thread. Axial spacing between the tension flanks and the compression flanks on the radially inner and radially outer spiral threads further define a stress reducing spiral root surface on at least one of the radially inner and radially outer threads and a corresponding crest surface on the other radially inner and radially outer spiral threads.
