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: A device inhibiting propagation of explosions using a pipe having an inlet and an outlet. The inlet is connectable to a container to be protected or to a conduit to be protected. The device further includes a mechanism for building up a pressure difference so that a higher pressure is generated in a first region of the pipe located upstream of the outlet in the direction of the inlet and a lower pressure is generated in a second region located upstream of the first region in the direction of the inlet.

Abstract: The invention relates to a device (1) inhibiting propagation of explosions, with a pipe (10) having an inlet (11) and an outlet (12), wherein the inlet (11) can be connected to a container (3) to be protected or to a conduit (2) to be protected, wherein the device (1) includes a means (17, 18, 19) for building up a pressure difference, wherein with the means (17, 18, 19) a high pressure can be generated in a first region (13) of the pipe (10) located upstream of the outlet (12) in the direction of the inlet (11) and a low pressure can be generated in a second region (14) located upstream of the second region (14) in the direction of the inlet.

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).
