Abstract: A rupture disk assembly comprises: a single-part or multi-part body with an opening that forms an outlet for a conduit or a container; a rupture disk that closes the opening and bursts subject to the action of a rupture pressure in order to unblock the opening; an actuator to reduce the rupture pressure, wherein the actuator includes a plunger to reduce the rupture pressure on the rupture disk, the plunger being configured to strike against the rupture disk; and a housing to receive the actuator, the housing including a housing opening for the plunger.

Abstract: This invention relates to an explosion pressure relief device with a wall and a framework fixing the wall. In the case of an explosion in a container to which an explosion pressure relief device is attached, such explosion pressure relief device serves to allow the pressure wave to escape at best greatly weakened.

Abstract: A device for measuring a mass flow (5) with guide means (4) having a surface shaped as a circular arc, across which the mass flow can flow during the measurement, and a force sensor (2), wherein the guide means (4) is supported above the force sensor (2) and the support occurs on a straight line extending through an endpoint of a radius vector TO of a resulting friction force F acting on the mass flow (5) in the direction of the resulting friction force F acting on the mass flow (5).

Abstract: 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.
