Abstract: A method and apparatus for dispensing compressed gas from n storage vessels containing compressed gas. Gas is sequentially dispensed from each of the storage vessels until predetermined delivery conditions are reached for each storage vessel. After the predetermined delivery conditions are reached in storage vessel n, storage vessel n is backfilled using the remaining compressed gas from the other storage vessels. The backfilling provides greater extraction of stored gas in the storage vessels and consistently fast fill times.

Abstract: A fuel tank having a trapping device arranged in its filler pipe for trapping fuel vapors during refuelling which has an internal closure flap which not only closes off an end of the filler pipe but also closes off connection to an activated carbon filter. Insertion of a fuel nozzle opens the flap valve.

Abstract: An apparatus for filling containers, under counterpressure, with carbonated liquids. The return gas that is to be withdrawn from a container that is being filled is conveyed, accompanied by a pressure differential, into a return gas chamber via a connection that is provided with a flow control mechanism. In this return gas chamber a pressure is regulated that is adjustable within a range that is between the filling pressure and the critical pressure of the flow control mechanism. In this way, the flow velocity with which the dispensed liquid flows into a container that is being filled can be smoothly adapted in an infinitely variable manner to the filling characteristics of a respectively dispensed liquid, and/or to the respective output requirements of the filling apparatus.

Abstract: An apparatus for filling a liquid friction pump with a liquid comprises a metering pump and plug connector means for connection to the liquid friction coupling. During a testing of the filling ratio of the liquid friction pump it may be necessary not only to supply viscous liquid to said coupling but also to withdraw viscous liquid from such coupling. For that purpose the plug connector means are preceded by a manifold, which communicates with two nonreturn valves, which normally prevent a flow of liquid from said manifold through said valves. A discharge line from the metering pump communicates with a first of said nonreturn valves. The second nonreturn valve is incorporated in a return line leading from said manifold to a reservoir, from which the metering pump is adapted to suck liquid. Said second nonreturn valve is adapted to be opened preferably by the application of pneumatic pressure for a flow in said return line from said manifold through said second valve to said reservoir.

Abstract: The disclosed gaseous fuel torch apparatus is adapted for use in cutting, welding, heating or other such operations involving the heating, cutting, or fusing of either metallic or non-metallic materials. The apparatus includes a fueling module for supplying gaseous fuel to a torch at an elevated pressure from a relatively low pressure gaseous fuel source, such as a natural gas supply system for example. The fueling module also preferably includes a selectively-operable alternate system for supplying such compressed gaseous fuel for other applications, including the recharging of one or more storage vessels for example. The fueling module includes features by which its gaseous fuel discharge pressure can be infinitely varied and preselectively adjusted within the capabilities of the fueling module's compressor device.

Abstract: Combustible fuel gas at low or moderate pressure is supplied to an inlet in the top of an upright working cylinder. The working cylinder then is filled with liquid through a bottom liquid inlet to force the gas from the cylinder and direct it into a storage cylinder. A check valve prevents backflow of gas from the storage cylinder as the liquid is drained from the working cylinder and as the working cylinder again is filled with low or moderate pressure gas. The process of filling the working cylinder with liquid to force the gas from it into the storage cylinder and holding the gas in the storage cylinder while the liquid is drained and the working cylinder is refilled with gas is repeated until the gas in the storage cylinder is a desired high pressure, such as 1500 psi or higher. Two working cylinders can be provided so that, as one of them is drained, the other is filled with liquid, such that gas is substantially continuously forced into the storage cylinder until the desired high pressure is achieved.

Abstract: An electrochemical cell, carried along a cell production line, is filled with liquid electrolyte under pressure. First, the electrolyte is dispersed on top of the cell electrode assembly within an open ended cell casing. Then a pressurizing chamber is mated with the cell support member of the conveyor mechanism so as to form a pressurizing volume surrounding the cell, whereupon a gas under pressure is introduced into the chamber and forces the electrolyte into the separator of the electrolyte assembly for rapid and complete absorption of the electrolyte.

Abstract: A filling device for use in a bottling machine, which device is provided with a sealing member for closing the opening of a bottle, a filling tube for supplying the bottle with a filling liquid and an exhaust tube for discharging the air from the bottle to the outside during the filling operation. When the opening of the bottle is closed by the sealing member, the filling liquid is fed into the bottle through the filling tube and the air in the bottle is simultaneously discharged outside. The filling device is provided with a valve mechanism which receives the pressure of the air remaining in the bottle as an indication pressure when the filling liquid in the bottle blocks the lower end of the exhaust tube. The valve mechanism closes the exhaust tube or the filling tube when the indication pressure exceeds a predetermined value.

Abstract: The present invention relates to valves for racking machines which are known as isobarometric machines comprising an upper reservoir which is actuated by a rotational movement and which is provided with a certain number of valve devices or tap devices making it possible to simultaneously fill several containers or bottles.
