A container may comprise a support frame with sides and at least one of the sides being an open side defining an opening, a flexible panel configured to at least partially cover the open side of the support frame, and a panel mounting assembly configured to removably mount the panel over the opening. The panel mounting assembly may comprise at least one panel mounting element including a leverage structure configured to provide a fulcrum edge along at least a portion of the opening, with the at least one portion of the panel being tensionable over the fulcrum edge. The panel mounting element may also comprise a tensioning structure mountable on the leverage structure and configured to selectively apply tension to the at least one portion of the panel with the thicker thickness over the fulcrum edge of the leverage structure.

A pump-storage device includes a tank, a treatment container, and a vacuum pump. The treatment container includes a first chamber in communication with an inlet. The first chamber includes a bottom wall having a first valve intercommunicated with a second chamber. The second chamber includes a bottom wall having a second valve. The treatment container includes a first control valve having a first duct in communication with the first chamber, a second duct in communication with the second chamber, and a third duct in communication with the tank. The treatment container includes an actuation cylinder for actuating an actuation rod to extend or retract. A first valve plate and a second valve plate are mounted on the actuation rod for controlling opening and closing of the first valve and the second valve. The treatment container includes a second control valve in communication with the first chamber and the vacuum pump.

A flexible tank for carrying liquid or liquid-based material in a vehicle chassis or in a container is provided, and the flexible tank has a body which defines a closed volume, at least one ring part which narrows the cross-section of said body and which forms at least one first compartment and at least one second compartment, and the flexible tank further has at least one filling inlet. Accordingly, the improvement is that the subject matter flexible tank includes at least one folding region defined between one each folding lines provided at a first distance at both sides of the ring part and folded onto or under at least one of the first compartment and the second compartment after approaching of the folding lines to each other.

An apparatus that provides a durable, reusable device with handles and adjustable straps and connectors, which may be padded internally, the external layer made of water-shedding or water-proof fabric, and thus able to effectively secure for transport a wide range of large, heavy or awkward items, without requiring a pre-cut or custom fit. The invention allows for a multiplicity of configurations and sizes, providing a virtually universal protective bag, with adjustable straps and connectors, and multiple built-in handles, to safely and securely transport any type of furnishing item, including but not limited to appliances, beds, sofas, loveseats, tables, shelves, entertainment centers, cabinets, dressers, and armoires.

A bag body 10 is filled with stones 12. A restraining rope 14 extends from the bottom of the bag body 10 through the center of the bag body 10 and is pulled up together with a lifting rope 15 to lift the bag body 10. The bag body 10 is within a predetermined range centered about a curve given by W/H1 (diameter/restraining rope length)=15.898?(W/W0).sup.2?17.784?(W/W0)+6.6314, where W represents the diameter of the bag body 10, H1 represents the length of the restraining rope 14 from the bottom portion of the bag body 10 to a root position of a mouth closing rope 13 of a bag material through the center of the bag body 10, and W0 represents the diameter when the bag material 11 is filled with the filling material 12.

Various techniques are provided for an energy absorbing fluid bladder. In one example, the fluid bladder includes a bladder body and a perforated baffle structure. The perforated baffle structure can be disposed within the bladder body and configured to mitigate a pulse of fluid (e.g., fuel) moving within the bladder body before the pulse reaches the bladder body. Related methods are also disclosed.

A container for filling, processing, transporting, storing, transferring, etc., of small parts for the pharmaceutical industry consists of a preformed, flexible container which has a predefined spatial shape and the form of which is changed by larger pressures due to its flexibility such that it may support enough pressure (e.g. 50-500 mbar) over a larger period (e.g. 1 year) in order to ensure the integrity of the content.
