The device for conveying fuel from a fuel tank (10) to an engine (18) of a motor vehicle has a conveying unit (14), communicating on the intake side with the fuel tank (10) and, on the pressurized side, with the engine (18), and a return line (22), which leads to a jet pump (24), located near a tank bottom (11), that pumps excess fuel via a mixing region into a reserve pot (12), from which the conveying unit (14) draws fuel. According to the invention a siphon-like mixing region (29) is provided between the reserve pot (12) and the tank bottom (11). An opening (32) or a filter element (48) is provided in a transitional region (31) of the mixing region (29) to the reserve pot (12). The opening (32) or filter element (48) which extends parallel to the tank bottom is closable by an axially movable closing element (44,51) so that a fuel flow can occur into the reserve pot (12) but not back from the reserve pot (12) into the mixing region (29).

The vehicle terminal includes a button module, a positioning module, a camera module, a control module and a prompt module, and managementserver includes a processing module and a database module. The device can obtain the image information of the accident scene through the emergency button, save the evidence of accident scene in time,and prompt the vehicle in the road to make the way, so that the rescue vehicle can reach the accident scene more smoothly and perform timely rescue.

A stopper includes a hollow casing with a resilient, ribbed sleeve that forms a valve seat. An interior plunger has a tip configured to mesh with the valve seat when in its down position and to open the valve when in its up position. An upper flange in the plunger provides an additional seal and is visible through a transparent wall in the casing. A vacuum in the bottle draws the plunger downward increasing the pressure with which the plunger presses against the seat, thus securing a long-lasting seal that maintains the vacuum in the bottle. When the vacuum is released, the resilience of the seat structure pushes the plunger upward, rendering it visible as an indicator of vacuum through the transparent wall. An opening in the casing allows connection to a pump to create the vacuum in the bottle.

At least one tube may be provided with one end attached to the container in communication with the interior of the container and the other end connected to a suction mechanism. When the fluid is evacuated from the container, the container constricts around the granular substance and becomes relatively rigid. An absorbent sleeve or layer may be provided surrounding the container. The granular substance may be provided as loose fill or as a layer over at least a portion of the inner wall. Alternatively, the inner walls of the container may be provided with a very rough surface. Further, the outer surface of the bottom of the pouch is enhanced frictionally.

A method for operating a device configured to deliver a liquid includes: a) back-suctioning a liquid situated in a pressure line section counter to a usual delivery direction by at least one pump; b) monitoring at least one operating parameter of the at least one pump during the back-suctioning, the at least one operating parameter being representative of a counterpressure that the at least one pump operates against during the back-suctioning; and c) detecting an increase in the counterpressure, and stopping the back-suctioning.

A device for employing sonic transmissions is utilized to determine fluid level in a well or a container. The device may be utilized while the well is operating. It is known that wells replenish fluid at different rates even in the same formation or well field. Increased well production at minimum pumping cost is achieved for a given well.

A bit assembly is for a percussive drill that includes a casing with an interior chamber and includes a bit connectable with the casing and having a longitudinal bore and an axis through the bore. The bore has a retainer portion with one or more generally. conical inner surfaces extending circumferentially about and facing generally toward the axis. A generally cylindrical valve has a longitudinal passage with an inlet fluidly connectable with the casing chamber and an outlet fluidly connectable with the bit central bore and an axis through the passage. An engagement portion with at least one generally conical outer surface extends circumferentially about and faces generally away from the valve axis. The valve engagement portion is disposable within the bit bore retainer portion such that the valve conical outer surface is disposed within and against the bit conical inner surface to retain the valve coupled with the bit.

The invention discloses an emergency guiding linkage system for an urban rail transit. The emergency guiding linkage system for the urban rail transit comprises an automatic fire alarming system, a linkage controller, a main controller, an emergency evacuation strobe light, an audible and visual alarm and an operation dispatching workstation, wherein the automatic fire alarming system is used foracquiring fire position information in a subway station; the linkage controller is used for reading the fire position information; the main controller is used for receiving the fire position information; the emergency evacuation strobe light is connected with the main controller; the audible and visual alarm is arranged at a passageway of the subway station, and is connected with the main controller; the operation dispatching workstation is connected with the main controller and is used for inputting emergency level marks; the main controller controls the emergency evacuation strobe light to indicate an evacuation direction and controls the audible and visual alarm to send out audible and visual alarming according to the fire position information or emergency level marks to guide passengers in the subway station to evacuate out of the station. By the emergency guiding linkage system for the urban rail transit, boundedness of a single guiding means can be avoided, meanwhile, automated systems of the subway station can be linked to guide and cooperate with evacuation of the passengers, and the passenger evacuation efficiency is improved.
