    • An apparatus for blocking a medium flow passage in a spray head, said apparatus comprising a blocking element (1), such as a burst disk, arranged in the passage and, when unbroken, blocking the passage of medium flow from a first side of the blocking element to a second side of the blocking element, on the first side of which blocking element a first pressure (p1) prevails in the passage (2) while on the second side a second pressure (p2) prevails in the passage (3), said blocking element (1) being arranged to be ruptured so that a medium flow passage is formed through the blocking element when the pressure difference between the first and the second sides of the blocking element reaches a preset value. The apparatus comprises a supporting element (4) provided at least on that side of the blocking element where the pressure of the medium is lower at least just before the instant of rupture of the blocking element, which supporting element can be moved between at least two positions, a first position where the supporting element supports the blocking element (1) so that the blocking element cannot be ruptured even if the pressure difference in the passage between the first and the second sides of the blocking element is greater than the preset value, and a second position where the supporting element does not support the blocking element.

    • A compressed gas release system including a compressed gas source (42), the gas within the source is released as a response to a combination of a predetermined threshold external pressure and a defined chemical environment. In particular, the compressed gas release system includes a housing defining a space; a material (64) being in the space and being solid in a first chemical environment and the material dissolving in a second chemical environment; a biasing member (62) being activated when pressed against the material when the material is solid and, the biasing member is relaxed when the material dissolves; a firing pin (52) including a gas releasing end and, the firing pin being fired when the biasing member is relaxed; a source of compressed gas, the source of compressed gas releasing gas as when the firing pin is fired; a diaphragm (50) having an internal side and an external side, the diaphragm being mounted onto the housing, the internal side of the diaphragm facing the space of the housing, thereby sealing the first chemical environment in the space.

    • A pressure relief panel assembly (20) for rupture discs, explosion vents and the like has a plurality of frangible panel portions (140, 44, 50) which burst at different pressures to present a pressure relieving aperture having a cross-sectional area which varies in accordance with the number of panel portions (40, 44, 50) which have ruptured. In one embodiment of the invention, the assembly comprises two frangible panels (26, 30) positioned in face-to-face relationship in covering disposition to a vent opening, and the innermost panel has an orifice which functions as a pressure relieving aperture once the outermost panel ruptures; subsequently, further build up of pressure causes the innermost panel to burst and present a pressure relieving aperture larger than the orifice so that the structure to be protected is fully vented. In certain forms of the invention, a dis­continuous pattern of perforated lines of weakness in the innermost panel serve as pressure relieving apertures once the outermost panel ruptures. In another embodiment, the assembly comprises a single panel (125) having one set of weakness lines (142) defining a first frangible panel portion (140) and a second set of weakness lines (142) surrounding the first set and de­fining a second frangible panel portion (144).

    • Bei einer Sicherheitseinrichtung gegen unzulässigen Druck in einem Behälter, ist ein schneidbares, in der Art einer Membrane ausgebildetes Verschlußelement (4) vorgesehen, das eine Druckentlastungsöffnung einer Behälterwand hermetisch abschließt. Dem Verschlußelement (4) ist eine Schneideinrichtung (5) zugeordnet, die in einerAusgangslage von einem starren Halteglied (6) gehalten ist, das unter dem Innendruck des Behälters steht und eine Sollbruchstelle (6a) aufweist. Das Halteglied (6) ist starr mit der Schneideinrichtung (4) verbunden, die ihrerseits starr mit einer Platte (8) verbunden ist. Das Verschlußelement (4) dagegen ist, ausschließlich eines freien Randes für den Angriff der Schneideinrichtung (5), zwischen der Platte 8 und einer weiteren Platte 9 eingespannt, die auf der dem Innendruck des Behälters entgegengesetzten Seite des Verschlußelementes (4) angeordnet ist. Alle anderen Teile (5, 6, 7, 8) der Verschlußeinrichtung befinden sich auf der vom Innendruck des Behälters beaufschlagten Seite des Verschlußelementes (4). Die Sicherheitseinrichtung spricht schlagartig an, wobei das Verschlußelement passive ist. Hierdurch wird die Materialauswahl freier und die Form des Umrisses ist nicht auf die Kreisform beschränkt.
