Abstract: A vapor pressure equalizer system for reducing the pressure of a storage tank that contains volatile liquid or fuel. A conduit is connected to the storage tank that draws vapors present in the ullage of the storage tank into the conduit. The vapors are circulated through the conduit to cool the vapor and return the vapor to the storage tank. In this manner, the pressure of the storage tank is reduced since the vapors being returned are cooler and smaller in volume than when the vapors entered the conduit. The conduit may be an open system that circulates vapors, or may be a closed system that circulates a cooling media through a radiator in the ullage of the storage tank. An electronic controller controls the operation of the system according to measurements that indicate an overpressure condition or a likelihood of future over-pressurization.

Abstract: A level sensor and fuel pump assembly insertable through an access hole of a fuel tank so that an elongated fuel pump is disposed substantially completely within the fuel tank, and so that a flange of the assembly covers the hole and is engaged sealably to the wall of the fuel tank. The fuel level sensor has an arm which projects generally laterally when in a biased operating position from the elongated fuel pump to a float at a distal end. During insertion of the fully pre-assembled fuel sensor and pump assembly through the access hole of the fuel tank, the fuel level sensor is pivoted from the biased operating position to a collapsed position by an external force thus pivoting the fuel level sensor generally parallel, and closely orientated, to the fuel pump. This temporary orientation permits insertion of the fuel pump assembly through the relatively small access hole of the tank.

Abstract: A method is described of operating a hot-chamber pressure diecasting machine and a pressure diecasting machine suitable for the implementation of this method, by which a prefilling of the casting system can be carried out before the actual mold filling operation. During this prefilling operation, the air present in the casting system after each shot when the casting plunger is withdrawn, is pressed out during this prefilling operation through the mold which is still open during this time period. This amount of air therefore no longer has to escape during the subsequent mold filling operation. The mold filling operation and the pressing-in operation can therefore be implemented more effectively and within a shorter period of time.
