Abstract: A device for coupling a propulsor to a marine vessel. The device includes a mounting bracket configured for attachment to the marine vessel. A support frame has a carriage and is configured for the propulsor to be coupled thereto, where the carriage is configured to slidably engage with the mounting bracket into a fixed position. A member is manually engageable to prevent the carriage from sliding out of the fixed position. The propulsor is coupled to the marine vessel by sliding the carriage into the fixed position and engaging the member, where the propulsor is operable to propel the marine vessel in water when the carriage is in the fixed position, and where the propulsor is configured for decoupling from the marine vessel by disengaging the member and sliding the carriage out of engagement with the mounting bracket.

Abstract: A multi-purpose tool that is compact, easily stored, and readily transported and can provide a substantial number of the tools needed on a typical camping trip or outdoor activity. A multi-purpose tool comprises an outer elongated nesting member, an intermediate elongated nesting member, and an inner elongated nesting member. In various configurations, the inner nestable member and the intermediate nestable member may extend from either end of the outer nestable member to form any number of elongated tools. In another configuration of the embodiment, the inner nestable member and the intermediate nestable member may be retracted to the end of the outer nestable member to form more compact tools. A number of application-specific heads may be operably coupled to the nestable members to form camping tools. In another configuration, the nestable members may be unnested and operably coupled as individual members to form tripod or non-linear-shaped tools.

Abstract: The present invention generally provides a method and apparatus for injecting a compressible fluid at a controlled flow rate into a geological formation at multiple zones of interest. In one aspect, the invention provides a tubing string with a pocket and a nozzle at each isolated zone. The nozzle permits a predetermined, controlled flow rate to be maintained at higher annulus to tubing pressure ratios. In another aspect, the present invention assures that the fluid is supplied uniformly to a long horizontal wellbore by providing controlled injection at multiple locations that are distributed throughout the length of the wellbore. In another aspect, the invention ensures that saturated steam is injected into a formation in a predetermined proportion of water and vapor by providing a plurality of apertures between a tubing wall and a pocket.

Abstract: Embodiments include providing a gas lift system comprising production tubing disposed within a wellbore, the production tubing capable of allowing fluid flow in a first direction from outside the production tubing through a wall of the production tubing to inside the production tubing to introduce a gas into the bore of the production tubing, while preventing fluid flow in a second direction from inside the production tubing through the wall of the production tubing to outside the production tubing. In one aspect, fluid flow in the second direction is prevented by operation of at least two valve members disposed within a side pocket of a side pocket mandrel in the production tubing. At least one of the valve members is capable of preventing fluid flow in the second direction even when the other valve member is removed from the wellbore or is at least partially inoperative.

Abstract: An air-cooled weather-protected motor (10) configured for vertical-shaft applications, such as mounting above an outdoor, vertical-shafted pump (P) for pumping fluid (e.g., water, oil, etc.) through a pipeline (L), is disclosed. The illustrated motor (10) broadly includes a stator (12), a shafted rotor assembly (14) rotatably supported relative to the stator (12), and a vented protective motor enclosure (16) enclosing the stator (12) and the rotor assembly (14). The enclosure (16) includes a primary motor housing (18) and a pair of filtration boxes (20) and (22) removably coupled to either side of the housing (18) to guard air intake through the housing (18) to the stator (12) and the rotor assembly (14). The improved motor enclosure (16) provides an inventive coupling mechanism that enables the modular filtration housings (20,22) to be quickly and easily secured to the primary motor housing (18) to protect the air intake openings (68,70) from weather and other undesired debris.
