A system for delivering objects from a fixed-wing aircraft has a first tether having a connector on a deployed end, an anchor apparatus fixed to a point on the ground, a slide ring assembled over the first tether, a drag line connected to the slide ring by one end, and a drag-producing device connected to at a second end, and an object carrying apparatus connected by a support line. The aircraft is flown at an altitude in an orbit at a diameter and a speed such that the deployed first tether assumes a spiral pattern. An object is placed in the object-carrying apparatus and released from the aircraft, with the slide ring guiding along the first tether, and the drag-producing element slows descent of the object in the carrying apparatus in the spiral pattern until the object reaches the ground, where the object is removed from the object-carrying apparatus.

Methods, apparatus, systems and articles of manufacture are disclosed for a first link to rotate about a pin joint, a second link rotatably coupled to the first link, the second link having a nozzle at a first end and a weight at a second end opposite the first end, and a fluid inlet including a funnel portion and an opening, the funnel portion having a conical taper converging towards the opening.

A distribution station includes a mobile trailer, a pump on the mobile trailer, a manifold on the mobile trailer and connected with the pump, a plurality of hoses in communication with the manifold, and a plurality of valves on the mobile trailer. Each of the valves is situated between the manifold and a respective different one of the hoses. Each of a plurality of fluid level sensors is associated with a respective different one of the hoses. The fluid level sensors are operable to detect respective different fluid levels. A controller is configured to operate the valves responsive to signals from the fluid level sensors, activate and deactivate the pump, identify whether there is a risk condition based upon at least one variable operating parameter, and deactivate the pump responsive to the risk condition.

A system and method for fueling multiple saddle tanks of hydraulic fracturing equipment from a single cart. The cart having multiple retractable fuel lines for providing and obtaining fuel. Each retractable fuel supply line uses a flowmeter, a ball valve, and an electrically actuated valve to provide remote control to a controller based upon a user's selected fueling requirements. An electronic reporting system provides fuel data to operators and users. Fuel data such as fuel tank status, amount of fuel usage over a stage level, a daily level, or job level along with a fill level of the fuel tank.
