Abstract: An actuation assembly for a refueling port or charging port flip cover assembly is rotatably mounted on a base and includes a locking means, a flip cover rotating shaft, a transmission gear, a drive gear and a drive member. The locking means is movably disposed on the base and configured to lock or release a flip cover. The flip cover rotating shaft is configured to rotate the flip cover and includes a fitting portion. The transmission gear includes a receiving portion and is installed around the fitting portion. The drive gear and the drive member are configured to synchronously rotate. The drive gear is meshed with the transmission gear and the drive member is configured to drive the locking means. In moving the locking means from a release position to a locking position, the drive gear blocks the rotation of the transmission gear and prevents the flip cover from opening.

Abstract: A refueling coupling has an annular fitting 101 having a bore 102, bayonet lugs 103 and slots 104 suiting it for connection to a pressure filling nozzle. A flange 122, drilled with screw holes for securement to a fuel tank (not shown), extends out from the fitting 101. Also not shown for the sake of clarity is a tube extending own from the flange. Rods extend down from the flange 122 to a spider 125, with springs bearing upwards onto the underside of a dry-break member 105, through which the rods extend. The rods, springs and spider are within the non-shown tube. On attaching and opening of a pressure filling nozzle to the coupling, the dry-break member 105 is displaced resiliently inwards fuel can flow past this member and into the tank. The dry-break member has a central aperture 111, normally closed by a plug 112, which is threaded externally 114 and carries an O-ring seal 115 above the thread. The central aperture has a plain bore orifice 116 and is threaded 117 below the plain bore.

Abstract: A fuel tank comprises a circular column-shaped fuel tank body, a handle, and a lock mechanism. The circular column-shaped fuel tank body is provided so as to be capable of being detachably attached to a fuel-powered device. The handle is formed on one end side in a length direction of the fuel tank body. The lock mechanism is capable of switching between a locked state in which the fuel tank body cannot be removed from the fuel-powered device, and a lock-released state in which the locked state has been released, due to the fuel tank body being rotated in a circumferential direction in a state of being installed to the fuel-powered device.

Abstract: It is imperative that the integrity of a train and its railcars be maintained. A defective part or parts on a train may cause the derailment of the train and its railcars. A derailment often causes serious personal and property damage. The use of artificial intelligence that has been applied to this system will detect possible flaws or defects in the railroad car. A portal through which the train will pass houses cameras and a means of illumination to take high resolution images of the train through the portal. This information is then stored on a software platform. It has a feature which can include a human in the loop process that verifies the accuracy of the information. The solution also transmits detected defect images and information to a remote location for analysis.

Abstract: A method for controlling a pitch angle of blades of a cooling fan of associated with a radiator of an engine, the blades extending radially from a central hub, the fan having an axis. The method includes regulating a pitch angle of the blades from a first limit value for which a cooling flux of the cooling fan has a first value to a second limit value for which the cooling flux has a second value greater than the first value. The pitch angle is determined based on quantities measured in the engine. The method further includes steps of detecting an engine speed; calculating a first derivative of the engine speed to detect accelerations of the engine; comparing the calculated first derivative with a threshold value and if the calculated first derivative is greater than the threshold value, setting the pitch angle to the first minimum limit value.

Abstract: A walk-behind lawnmower and accompanying method of use allows for height adjustment of the cutting deck relative to all four wheels simultaneously. This is achieved using a linkage that runs along the cutting deck and that connects the front and rear wheel assemblies. Movement of the entire mechanism is achieved using a lever operatively connected to the linkage. The linkage is retained in place through the use of a locking mechanism. The locking mechanism includes a locking pin, a pin engagement mechanism, such as a lug, provided on the linkage, and an array of pin receptacles spaced longitudinally along the cutting deck. The pin engagement mechanism selectively engages the pin when the pin engages a designated pin receptacle on the cutting deck, retaining the cutting deck at a height determined by the prevailing location of the pin which, in turn, is determined by the selected pin receptacle.

Abstract: The present invention provides a power device generating greater propelling force and finds that traditional power devices do not include all propelling forces based on the fundamental core propelling force source problem. External pressure is guided to the traditional power devices since the inner speed is higher the outer speed, power consumption for overcoming fluid resistance is high, and mutual contradiction results are obtained. The unique difference between the present invention and general common sense lies in opposite fluid pressure directions; inner fluid channels and outer fluid channels with higher flow speeds are formed to generate pressure differences which guides the fluid pressure to the outside and serve as propelling force, thus the present invention creatively finds three propelling force sources, two lifting force or propelling force sources of helicopters or airplanes driven by propellers and two propelling force sources for sufficient burning of fuel in combustion chambers of engines.

Abstract: A brush cutter device having a latch assembly for securing a movable cutter guard in a closed position when the brush cutter is tilted beyond a predetermined angle. The guard is combined with a side of the housing and movable between a closed position and an open position. A latch is combined with a portion of the housing and is capable of moving between a retracted position wherein the guard is able to move freely between its open position and its closed position and an engaged position wherein the latch prevents the guard from moving to its open position. Upon tilting the brush cutter beyond a certain angle, gravity acts on the latch causing it to move from its retracted position to its engaged position. The guard would move from its closed position to its open position upon tilting the brush cutter beyond a certain angle, however, the latch is moved beyond its pivot point before the guard moves beyond its pivot point to lock the guard in its closed position.
