A lightning protection system can include a storage battery comprising at least one tank, a pressure control valve coupled to the storage battery, a vacuum pump fluidly coupled to the storage battery, and a controller communicatively coupled to the vacuum pump that executes a lightning protection application that modulates the vacuum pump to draw a vacuum within the storage battery.

A fleet refueling silo tank system gravity feeds fuel through hoses to fleet units without requiring pressurizing pumps. Specialized valves at the fleet unit fuel tanks prevent vapor escape and admit fuel at low, gravity fed pressures. The cylindrical silo tank includes an upper, gravity feed dispensing chamber and a lower reservoir chamber. A fuel pump doubles as means for moving fuel from the reservoir chamber to the dispensing chamber and for refilling the reservoir from fuel delivery trucks. Onboard telemetry transmits fuel consumption and flow rates wirelessly to a control center where operators monitor safety parameters in real time. Stored data may be analyzed to calculate fleet unit maintenance and service intervals. A tractor trailer hauls the silo tank horizontally on roads and highways and includes a gantry and hydraulic lifts to erect the silo tank into vertical operating position supported by a built-in platform.

A container (10) is produced from a spiral-shaped, bent sheet strip (20) having a first edge section (22) extending in a spiral shape, being bent, and forming a bending edge (24) extending in a spiral shape toward the inside or the outside of the container (10). The sheet strip (20) has a second edge section (32) opposite the first edge section (22) in the longitudinal direction of the sheet strip (20) and extends in a spiral shape. The second edge section (32) overlaps a third section (28) opposite the first edge section (22) in relation to the bending edge (24) and is adjacent to the bending edge (24). The second edge section (32) and the third section (28) are welded to each other in the region of the overlap (30). The welding seam (40) extends at least partially into the region between the second edge section (32) and the third section (28) of the sheet strip (20).

A safety door latch system is presented for a grain bin having a door frame. An inner door is connected to the door frame that is configured to move between an open position and a closed position. An outer door is connected to the door frame and is configured to move between an open position and a closed position. A safety mechanism is connected to the door frame and is configured to move between an open position and a closed position. When the inner door frame is moved to a closed position, a portion of the inner door engages the safety mechanism thereby causing the safety mechanism to move to the closed position. When the safety mechanism is in the closed position, the outer door may be latched to the safety mechanism. When the safety mechanism is in the open position, the outer door cannot latch to the safety mechanism.

A robot comprises an auger-based drive system, a memory, and a processor coupled with the memory and configured to control movement of the robot via the auger-based drive system. The processor obtains a first measurement of an angle of slope of a portion of piled granular material in a bulk store. In response to the first measurement satisfying a first condition, the robot traverses the portion of piled granular material to incite sediment gravity flow in the portion of piled granular material by disruption of viscosity of the portion of piled granular material through agitation of the portion of piled granular material by auger rotation of the auger-based drive system. The processor obtains a second measurement of the angle of slope of the portion of piled granular material. In response to the second measurement satisfying a second condition, the robot ceases traversal of the portion of piled granular material.
