Abstract: A single-point connection apparatus for a closed fluid transfer delivery system having a mobile dispense to transfers liquid from a chemical delivery vessel to a chemical-receiving device, e.g., a dry cleaning machine, with return flow of vapor therefrom to the delivery vessel. A first passage selectively connects the delivery vessel to the liquid-receiving device. Liquid is only then pumped to the liquid-receiving device. A second passage connects the receiving device to the delivery vessel for a vapor return flow. A chamber of the apparatus has a filling valve to receive a filling adapter to deliver liquid. Associated with the filling valve is a relief valve mechanism providing continuous, uninterrupted liquid flow at an increased liquid flow rate through the first passage, inhibiting backflow of liquid through the second passage for continuous, uninterrupted vapor flow from the liquid-receiving device while liquid is being received by that device.

Abstract: A lightweight carbon fiber air/gas supply vessel storing high pressure air/gas. The air/gas supply vessel output is controlled by an adjustable pressure reduction valve which varies output pressure from very high to low pressure levels. An alternative multi-valve system uses a first pressure reduction valve to reduce output pressure from the very high levels in the air/gas supply vessel to an intermediate pressure level, and a second pressure reduction valve that reduces the air/gas pressure from the intermediate level to a fine tunable low pressure level. In both embodiments, the output of the last pressure reduction valve used is connected to a high pressure cable which in turn uses a standard universal fitting which can be coupled to most pneumatically powered equipment. Additional high pressure reservoir vessels can be used to replenish the lightweight air/gas supply vessel when its supply of air/gas is depleted.

Abstract: Fuel is dispensed into a fuel tank fill tube by a hand-held tool assembly having a body with an outlet tube connected to a fuel supply passage through an air actuated control valve. Spring biased arcuate jaws surround the outlet tube and expand outwardly into engagement with an inner surface of the fill tube by an air actuated annular clamping piston surrounding the outlet tube. An air actuated annular sealing piston surrounds the clamping piston and is effective to seal the outer end of the fill tube after the fill tube is clamped. The position of the fill tube is sensed by a pin which actuates a proximity switch, and a handle and fluid line connectors projecting from the body at right angles to the outlet tube. Thumb operated control switches are located adjacent the handle.

Abstract: The present invention relates to a system which makes use of a multiple reel on which groups of flexible lines supported by articulated structures (8, 9) are wound. The groups of flexible lines are interconnected at one end to flexible production and utility lines (4) emerging from the seabed and, at the other end, to connection blocks (10, 11) which may be connected to connection plates (15, 16, 17, 18) on at least one connection tower (13, 14) fixed to the vessel. As the connections are redundant, it is always possible to reposition one group of flexible lines while another group is connected, which gives the transfer system (2) total freedom of movement.
