Abstract: A safety coupling for the releasable connection of a nozzle to a duct system is disclosed. The safety coupling is adjustable between a coupled position, in which the coupling parts are coupled together to lock the connection of the nozzle to the duct system, and a decoupled position, in which the coupling parts are separable to allow release of the nozzle from the duct system. An actuating member is arranged to move the coupling member from the coupled position into the decoupled position when the coupling member is subjected to a disengagement force exceeding a predetermined limit value.

Abstract: The invention relates to a safety coupling, for the releasable connection of a nozzle to a duct system, which nozzle and duct system form part of an extraction system. The safety coupling comprises a coupling member having a first coupling part, which is adapted for fitting in the nozzle, and a second coupling part, which is adapted for fitting in the duct system. The first and second coupling parts are adapted to be brought together for connection of the nozzle to the duct system. In the joined state of the coupling parts, the coupling member is adjustable between a coupled position, in which the coupling parts are coupled together to lock the connection of the nozzle to the duct system, and a decoupled position, in which the coupling parts are separable to allow release of the nozzle from the duct system.

Abstract: Disclosed is an adhesive for gluing of biological tissue, in particular human body tissue. The adhesive contains fibrinogen, a substance capable of supplying calcium ions, blood-coagulating factor XIIIa and, as a fibrinogen-splitting substance, a snake-venom enzyme.

Abstract: A method and an apparatus for sucking up and transporting liquids of various kinds through a suction unit (D) to a mixing and defoaming unit (F). A liquid or a liquid/air/gas mixture is sucked up by a suction nozzle (17) at the end of a suction unit (D) and, concurrently therewith, a dosing unit (E) with an additive (20, 20') is sucked up, proportionally to the amount of sucked up liquid from the nozzle (17). The dosing agent (20) is supplied directly into the liquid, as soon as there is any liquid in the suction unit (D) whereby, and is controlled such that no dosing agent is supplied to the mixing and defoaming unit when only air is sucked up through the nozzle (17). The fluid and dosing agent is passed into the mixing and defoaming unit (F) and is subjected to a G-force via a flexible hose (27) which is clamped between two mounts (30, 31). The intermediate portion of the flexible hose is rotated by an eccentric carrier (32) to provide a centrifugal G-force.

Abstract: A method and a device designed to suck and to convey various types of liquids through a suction hose (45) and at the same time does (4) an additive to the liquid in an accurate proportion to the amount of the sucked liquid. A liquid or a liquid/air/gas mixture is sucked by means of a suction nozzle (2,45), which is influenced by a certain pressure P2 with a moderate suction action, and is passed through the suction hose (45). A dosage device (4), which includes a flexible dosage container (20), which is enclosed in a rigid casing (21), and which is influenced by a certain relatively lower pressure P3 (providing a stronger suction action) than the pressure in the suction hose (45), is connected directly to the suction hose (45).
