A hinge assembly for a rupture disk is disclosed. More particularly, a hinge assembly is disclosed having a first hinge member with a flange body and a collapsible hinge, and a second hinge member with a platform hinge, wherein the collapsible hinge is configured to be positioned between the platform hinge and a rupture disk. A rupture disk hinge is also disclosed, having a flange body and a collapsible hinge extending from the flange body. The collapsible hinge may have an approach extending from the flange body, a platform extending from the approach, and a lip extending from the platform. A rupture disk hinge also is disclosed having a hinge extension that extends along a diameter of a flange body across a central fluid flow path.

The invention relates to a container (1) for a fluid for metering a reagent into a microfluidic system. The container comprises a chamber (4) and a first film (3) which seals off the chamber (4) so that the fluid is encapsulated in the chamber. Advantageously, the first film (3) is an aluminum sealing film. A second film (7) is sealingly arranged on the first film, for example by adhesive bonding of the film layers. The films differ in their tear strength such that when pressure is applied simultaneously to both films the first film tears while the second film deforms elastically and/or plastically. By tearing the first film a connection is produced between the container chamber and an inlet channel so that a fluid contained in the chamber flows into the microfluidic system.

A rupture disk is provided for relieving pressure between the interior of a battery box and the exterior of the battery box, the box having an outlet opening. A first layer provides a gasket which abuts the battery box, the gasket having a central opening which aligns with the battery box opening. A second layer is in the form of a reverse buckling disk having a disk flange, a domed portion and a weakened portion on the dome that defines a disk burst pressure, the second layer having concave and convex sides. A third layer that is an outlet ring that sandwiches the second layer in between the first and the third layer layers, the outlet ring having a central opening surrounded by an edge. A plurality of teeth on the third layer extend from said edge inwardly. A plurality of tabs are provided on the first and third layers.

The present invention is directed to pressure relief devices and to corresponding pressure relief assemblies that have improved vacuum resistance, improved fragmentation resistance, and/or improved burst control while maintaining low mass. The pressure relief device includes a substantially flat flange section and a domed section. The domed section may include a transitional line that defines a change in the shape of the domed section. The pressure relief device may also include a bracket for securing or aligning a domed section to a flange section. The pressure relief device may further include a stress distribution feature that is disposed transversely to a line of weakness in the domed section. The pressure relief assembly may include a fastener having a wire that is configured to break and release the pressure relief device when subject to a predetermined tensile load.

A rupture disk (20), along with associated methods, is disclosed. More particularly, a miniaturized rupture disk is disclosed, comprising a transition area (23) configured to determine a pressure at which the rupture able portion will rupture. A method for forming a rupture disk is also disclosed, wherein a radius (R) of a transition area is configured to set the burst pressure of the rupture disk. A rupture disk having an indent at its apex (24) and a circular line of weakness configured to improve opening performance is also disclosed. Additionally, a method of relieving pressure in a pressurized system is disclosed, wherein a set of rupture disks is provided, wherein each rupture disk in the set has a different radius of transition area. A rupture disk may be selected from the set and installed based on a burst pressure set by the radius of transition area.

The bursting disc assembly has a primary bursting disc (10) and a secondary bursting disc (20) immediately behind and supporting the primary bursting disc. Each of the said discs (10,20) is made of metal and is gas impermeable, and the bursting strength of the assembly is derived from both of the bursting discs acting in combination. The primary and secondary bursting discs are in contact over the whole of the operating area of the disc, and are shaped together as a pair. The materials of the two discs can be chosen suitably for their functions. The primary disc is for example corrosion-resistant.

The invention concerns a Diesel engine, in particular a two stroke crosshead large Diesel engine comprising at least one combustion chamber, which is enclosed on multiple sides by a cylinder, and by at least one upper side of at least one piston moving up and down in the cylinder, which form an outer wall for the combustion chamber, wherein the combustion chamber on its outer wall presents a predetermined breaking point. The predetermined breaking point is suited to protect the Diesel engine against possible damages which might be caused by an undesirably high overpressure (py) of gases in the combustion chamber during a malfunction of the Diesel engine, wherein the predetermined breaking point comprises a predetermined breaking pressure (ps) below the overpressure (py) above which damages are expected, and above a combustion chamber normal pressure (pn) provided at a maximum during normal engine operation conditions. A predetermined breaking component comprising the predetermined breaking point, and a method in which for preventing the damages at least one predetermined breaking component is provided in the outer wall of at least one combustion chamber.

A tear out test plug for plumbing installations includes a cylindrical body having a peripheral sidewall, a closed end and an open end. A positioning flange extends outwardly from the peripheral sidewall at the open end. An end wall closes the closed end. A frangible strip extends from the open end, down the peripheral sidewall, and across at least a portion of the end wall.

A method for manufacturing a bursting disk from a sheet or foil is disclosed. The bursting disk has an edge for clamping the bursting disk in a clamping device and a middle region enclosed by the edge, with the following manufacturing steps: the sheet or foil is clamped with a first portion forming the future edge of the bursting disk, said first portion defining a second portion which corresponds to the future middle region of the bursting disk. A third region is defined, which is located within the second portion of the sheet or foil, a part of the second portion enclosing the third portion of the sheet or foil is clamped completely by means of a pair of clamping jaws or female dies, the sheet or foil is deformed for a first time in the third portion, the third portion being located within the second portion, which remains undeformed.
