Abstract: A manual reset actuator includes a main drain, a diaphragm release aperture fluidly coupled to a flow control valve, an upper chamber, a control port, a control orifice, an upper chamber supply orifice, and a sealing assembly, which includes a button, and a plunger. A pressure in the upper chamber exerts a downward force on the plunger. A spring exerts an upward force on the plunger. The fluid in the upper chamber is released via the control orifice, which lowers the pressure in the upper chamber, decreasing the downward force exerted on the plunger. When the downward force is less than the upward force, the spring forces the plunger upwards into an open configuration, which unseals the diaphragm release aperture. When the upward force is less than the downward force, the plunger remains in a closed configuration, which keeps the diaphragm release aperture sealed.

Abstract: A fluid-conveying device for conveying a fluid, such as in particular water, from a tank. The fluid can be conveyed along a dosing line to an injection point by a pump, wherein the dosing line is attached at a pressure side of the pump by a connection plug which is attached to an outlet line. The fluid-conveying device has at least one first valve, which is preloaded by a spring and which is configured to prevent a fluid flow from the dosing line to the outlet line and which is furthermore configured to permit the fluid flow from the outlet line to the dosing line if a predefined minimum pressure p1 is reached on that side of the first valve which faces toward the outlet opening.

Abstract: This disclosure relates generally to blowout preventers, or “BOPs,” for use in a well. The BOPs according to the present disclosure can include a substrate assembly, which can include a substrate body having a base and a protrusion. The substrate assembly can also include pressure components. The substrate assembly can result in overall improved BOP performance. Additionally, whereas prior art BOP ram bodies are typically made of rubber, BOP ram bodies according to the present disclosure can also include graphene. This results in a harder BOP ram that is more resistant to wear and tear. Normally the additional hardness would result in difficulty forming a seal in the well, but this problem is alleviated by the substrate assembly design.
