Abstract: An overfill prevention valve that is testable to ensure proper functionality of the valve. More particularly, in one embodiment the invention is an overfill prevention valve system including an overfill prevention valve having a blocking component. The blocking component is movable between a closed position, wherein the blocking component generally blocks fluid from flowing through the valve, and an open position, wherein the blocking component generally allows fluid to flow through the valve. The valve further including a float operatively coupled to the blocking component. The system additionally has an actuator that is operable to directly or indirectly move the blocking component to at least one of its open or closed positions to thereby enable testing of the overfill prevention valve.

Abstract: A gravity-fed fuel delivery system is provided. A central storage tank holds fuel to re-supply a number of pump trucks or other mechanized equipment, such as on a hydraulic fracturing location, and can be selectively raised or lowered. Hoses or other conduits extend from the central storage tank to individual fuel tanks of the equipment to be refueled. Adapters allow connection of the distal end of each hose or conduit to an inlet opening of a fuel tank. A float valve assembly senses when fuel inside an individual fuel tank is below a predetermined level, thereby mechanically opening a valve assembly to permit fluid to flow from the central storage tank, through a conduit, through the float valve assembly and into the fuel tank.

Abstract: A method for preventing mesothelial cell trauma is described. The method comprises applying at pool of conditioning techniques prior and/or during surgery for decreasing detrimental factors and optimally using beneficial factors. The pool of conditioning techniques thereby comprises at least applying an irrigation liquid to irrigate at least part of the area of surgery wherein the irrigation liquid is a pH buffering liquid.

Abstract: A simple and reliable locking device for a quick-action connection coupling for transferring gaseous and/or liquid fluids, especially for refuelling vehicles, is provided. Said device comprises a hand lever (50) for actuating a valve and a lock which is positioned on the end side thereof and engages with a hand grip (45) in the refuelling position. To this end, an unlocking lever (46) which can be pivoted on the hand grip (45) is mounted adjacent to the end region of the hand lever (50). The unlocking lever (46) comprises at least one, preferably two laterally protruding journals (47), arranged inside the hand grip (45), especially for simple handling.

Abstract: A simple design of an actuating device for a rapid coupling used for transferring gaseous and/or liquid fluids includes a tubular housing and a slide which is movably mounted relative to the housing and is coupled to a lever mechanism that is provided with at least one pivoted lever laterally mounted on the housing. At least one connecting lever extends to the slide on the pivoted lever, thus also obtaining safe handling.

Abstract: A portable cleaning apparatus comprises a base module for movement along a surface and a plenum. The base module comprises a base housing enclosing a fan for moving air through the housing from the interior of the housing to the exterior of the housing through an exhaust outlet in the housing. The plenum fluidly communicates at one end with the exhaust outlet and at another end with at least one plenum outlet opening adjacent the surface to direct air exhausted from the housing interior along the surface.

Abstract: A device for filling an aerosol container with a liquid using in particular a filling arrangement equipped with a pusher element, includes a cup that is designed to accommodate the liquid for filling the aerosol container, this cup being provided on its bottom with an injection opening that can be adapted to the valve of the aerosol container, a piston head acting by pushing on the filling liquid contained in the cup for transferring it from the cup to the container. The piston head has the form of a scraper in continuous contact with the inside wall of the cup during the transfer operation, this piston head being shaped to work with the cup after transfer to keep the piston head within the cup to form an airtight wall that retains the residual liquid that has not been transferred within the cup.

Abstract: A method and an apparatus (1) serve to place tablets (2) into pockets (3) of thermoformed bottom foil (4). The tablets (2) are accumulated as they are located in their flat position. The tablets (2) are rotated in an erecting station (9) such that they reach an approximately upright position. A plurality of lines of approximately upright tablets (2) is formed. The approximately upright tablets (2) are rotated back into their flat position by a transfer unit (24) including a plurality of channels (28). The tablets (2) are then placed into the pockets (3) of the bottom foil (4) by the transfer unit (24).

Abstract: A liquid filling apparatus includes a discharge head having a cavity for storing liquid, a nozzle communicated with the cavity, and a discharge device for discharging liquid stored in the cavity through the nozzle. In addition, the apparatus includes a liquid supply section which supplies the liquid to the nozzle of the discharge head by contacting the liquid with the nozzle, and a suction device connected to a cavity side of the discharge head, which draws liquid supplied from the liquid supply section to inside the cavity, by suction from the nozzle via the cavity.

Abstract: A process for the dynamic manufacture and packaging of gas mixtures containing a first component and a second component in predefined proportions, the first and second components being chosen from the group formed by O2, N2, He and N2O, in which predetermined proportions of the first and second components are dynamically mixed in order to obtain a gas mixture of the desired composition and the temperature of the mixture is adjusted in order to keep it above the demixing threshold temperature of the mixture. This process is particularly suitable for the production of analgesic gas mixtures that can be used in the medical field, particularly a mixture formed from 50% oxygen and 50% nitrous oxide.

Abstract: A float actuated valve for automatically shutting off the flow of fluid into a storage tank when the tank is filled to a predetermined level includes a pair of shutter plates movable transversely across the flow passage from an open position wherein the plates are retracted clear of opposite sides of the passage and a fully closed position in which the plates project into and cooperatively block the passage. A spring biased rotary trip plate underlying the shutter plates controls actuation of the shutter plates and may be held by first and second detents in rotative positions locating the shutter plates in the fully closed or a partially closed position. A lower float located within the tank releases the first detent to cause the trip plate to drive the shutter plates from the fully closed to the partially closed position when the level of fluid in the tank rises to a first level.
