20080216916 | FUELING SYSTEM VAPOR RECOVERY AND CONTAINMENT PERFORMANCE MONITOR AND METHOD OF OPERATION THEREOF - A method and apparatus for monitoring and determining fuel vapor recovery performance is disclosed. The dispensing of liquid fuel into a tank by a conventional gas pump nozzle naturally displaces a mixture of air and fuel ullage vapor in the tank. These displaced vapors may be recovered at the dispensing point nozzle by a vapor recovery system. A properly functioning vapor recovery system recovers approximately one unit volume of vapor for every unit volume of dispensed liquid fuel. The ratio of recovered vapor to dispensed fuel is termed the A/L ratio, which should ideally be approximately equal to one (1). The A/L ratio, and thus the proper functioning of the vapor recovery system, may be determined by measuring liquid fuel flow and return vapor flow (using a vapor flow sensor) on a nozzle-by-nozzle basis. The disclosed methods and apparatus provide for the determination of A/L ratios for individual nozzles using a reduced number of vapor flow sensors. The disclosed methods and apparatus also provide for the determination of fuel dispensing system vapor containment integrity, and the differentiation of true vapor recovery failures as opposed to false failures resulting from the refueling of vehicles provided with onboard vapor recovery systems. | 09-11-2008 |
20090071566 | DEVICE FOR FILLING VESSELS - A device for the filling of vessels, with a container for liquid and pressurized gas and at least one filling pipe connected with this, which filling pipe comprises a liquid valve and a return gas pipe, whereby a gas pipe discharges into the filling pipe outside the return gas pipe, which gas pipe is connected with the container by means of a pre-stressing valve, so that the pre-stressing valve is positioned on the upper side of the container and the gas pipe discharges into the container from above. | 03-19-2009 |
20100037983 | NECK RING SEAL - A filling valve device having a gripper and a container mouth seal, in which vertical movement of the gripper holding an empty beverage container relative to a filling valve causes a filling valve container mouth seal to be brought into contact with a neck ring to form a gas seal and fill a beverage containing carbon dioxide. The cross-sectional shape of the container mouth seal approximates an inwardly facing lip shape. Flexibility is imparted in the vertical direction of the filling valve. The inside of the container mouth seal is brought into contact with the neck ring during beverage filling, and a sealing force is applied to the beverage container and the container mouth seal by the gas pressure applied during filling. | 02-18-2010 |
20140076460 | OIL FILLING NOZZLE WITH VAPOR RECOVERY FUNCTION - To provide an oil filling nozzle with vapor recovery function capable of controlling opening degree of a vapor passage depending on flow rate and adjusting recovery rate. The oil filling nozzle includes a discharge pipe | 03-20-2014 |
20140096866 | TIPLESS CAN FILLING VALVE - A filling valve is provided for filling containers such as beverage cans. The valve includes a tipless nozzle having ports oriented for directing flow. The nozzle includes a valve seat having a planar sealing surface. A spring actuated vent seal is provided for closing the vent tube. The valve stem may have protrusions for centering the stem in the valve body. The filling valve may have a bell forming a cavity between the bell and the valve body, and an aperture for directing cleaning fluid from within the bell to the cavity. The valve body may have a duct for directing cleaning fluid from the cavity to an outlet. | 04-10-2014 |
20150053307 | DISPOSABLE VALVE AND FLEXIBLE CONTAINERS FOR PRESSURIZED BIOREACTORS - Disclosed herein are embodiments of a valve assembly for preventing dead leg spaces in a container or tubing, the embodiments including a three-way valve system for controlling back-pressure in a fluid generating device, such as a single-use high pressure bioreactor. Also disclosed is a pressurized reactor system for bioprocessing, comprising a single-use container including a flexible wall or a semi-rigid wall. | 02-26-2015 |
