A sustained drain system circuit and a sustained drain quality control system are constructed in which no mechanical or electrical driving and control mechanism is required at all, siphoning automatically occurs when some volume of urine is retained in the urinary bladder by the mass of urine, its potential energy, intrinsic pressure of filling and contraction of the urinary bladder, and abdominal pressure, and sustained drain continues even with a portion with a height difference higher than a drain source. In the sustained drain system circuit, a fluid is caused to be sustainedly drained by siphoning from an intracorporeal elastic closed space that can extend and contract as a drain source. The circuit is a siphoning circuit in which an inner diameter of a pipe space is designed so that a siphoning volume condition is satisfied and the fluid is drained as filling without a gap.

A liquid container, meeting all federal, state and local regulations, comprising a vessel with an opening and a self-venting spout which is mounted to the vessel in a manner allowing the spout, from a stowed position, to rotate into its operational position and coupling to the opening with a coupler. Both open ends of the spout are automatically covered when stowed. A valve assembly at the opening of the vessel is operated externally by a trigger located near the underside of the primary handle. The valve assembly controls flow of liquid out of the vessel and through the self-venting spout. Venting of the vessel is allowed through a series of channels, respectively comprising an interior channel within the spout, an intake port, and an intake channel leading to the rear of the vessel above the liquid line. The vessel opening is covered by a lid mounted to the vessel that rotates into operational or stowed position and is sealed by the coupler.

A rigid entry fitting configured to form a seal between a flexible pipe segment and a sump wall includes a fitting body having an inner surface defining a tapered opening, an insert received in the tapered opening, a shell received in an opening of the insert, a first pair of gaskets between an outer surface of the insert and the inner surface of the fitting body, a second pair of gaskets contacting an inner surface of the shell and opposite ends of the insert, and a nut configured to engage threads on an outer surface of the fitting body. When the nut is threaded onto the threads, the nut presses the shell and the insert into the tapered opening and presses the first pair of gaskets against the inner surface of the fitting body and the second pair of gaskets against the outer surface of the flexible pipe segment.

A pouring spout for dispensing a liquid present in a liquid container is provided. The pouring spout includes a first tubular body for connecting to the liquid container and a second tubular body which together with the first tubular body forms a passage for dispensing the liquid. The first and second tubular bodies are telescopically movable here relative to each other for leaving clear a radial opening through which the liquid can leave the pouring spout. The pouring spout further includes a venting channel for drawing in air. The invention is characterized in that the venting channel is fixedly connected to the second tubular body.

A weldless thru wall fitting that provides a leak free connection to a vessel that can easily be installed and removed. The fitting also provides an integrated, removable, and repositionable dip tube to allow the liquid stored in the vessel to the drained via gravity to a level below the entry point of the fitting.

A fuel cell-type industrial vehicle according to the present disclosure includes a vehicle main body in which a fuel cell unit is installed, and controller configured to control operations of the vehicle main body. The fuel cell unit includes a charging plug which is connectable to a charging socket for supplying fuel gas, and a detection mechanism configured to detect the connection state between the charging plug and the charging socket. The detection mechanism includes a sensor having an output signal that shifts in accordance with the connection state of the charging socket relative to the charging plug. The controller prohibits operation of the vehicle main body after determining, on the basis of the output signal of the sensor, that the charging socket is connected to the charging plug.

Described herein is a fuel authorization program that requires data to be dynamically retrieved from a vehicle data bus during the fuel authorization process. This can be implemented using a smart cable that is installed in enrolled vehicles. The smart cable includes a housing suitable for commercial environments, a cable to logically couple the smart cable to the vehicle data bus, a second data link to be used to logically couple the smart cable to a fuel authorization “puck” in a vehicle, and a controller. The puck handles communication with the fuel vendor. The controller automatically implements the functions responding to a query from the puck received over the second data link by dynamically acquiring data from the vehicle data bus using the first data link, and conveying the data to the puck using the second data link.
