An example system for deployment of a compacting head in a waste compartment includes an eutectic alloy fusible link positioned within a waste compartment that breaks at or above a predetermined temperature, a spring tensioned deploy lever that is deployed based on a break of the eutectic alloy fusible link, a pivotal joint assembly that collapses based on deployment of the deploy lever, and a compacting head of a trash compactor that is deployed to compact contents of the waste compartment based on collapse of the pivotal joint assembly.

A system includes a fusible cap, an adapter, and a hydraulic valve. The fusible cap includes a fusible body having a first box end. The first box end has first box threads. The adapter includes a first pin end and a second box end. The first pin end has first pin threads, and the second box end has second box threads. The hydraulic valve includes a second pin end having second pin threads. The first box threads mate with the first pin threads to form a first connection and the second box threads mate with the second pin threads to form a second connection.

A fluid flow control valve includes a valve body having a bore configured to convey fluid from an inlet port to an outlet port. The inlet and outlet ports, and the bore therebetween, define a fluid flow path through the valve body. A gate element is disposed in the bore. The gate element is positionable in the bore from a first position, which allows fluid flow through the bore, to a second position which restricts fluid flow through the bore. An actuator is coupled to the gate element and is configured to urge the gate element from the first position toward the second position. A fuse consisting of a transformable retainer is configured to retain the gate element in the first position, while the retainer is in a first condition, and to allow the gate element to move toward the second position when the retainer transforms to a second condition. The transformable retainer may be configured to transform from the first condition to the second condition responsive to a signal, e.g., a signal indicative of a thermal change or a fluid leak. The innovative valves are especially but not exclusively suited for governing flow in a heat transfer system, particularly a heat transfer system for dissipating heat from a plurality of computer servers. The innovative valves may be embodied in systems, methods, apparatuses, and components.

When using oxygen gas pipes 3, situations can arise, in particular due to slag return and similar dangers, in which the operator must initiate safety measures. Slag return safety devices are known which, in such a case, ensure that the gas flow is stopped by melting a cap 35 of a heat sensor 5. The response of this outlet valve 6 of the slag return safety device can be recognized, for example, by the fact that the inlet pressure of the existing oxygen gas 4 is used to push pins 21 located in the wall 19 of the oxygen gas pipe 3 beyond the outside 27 of the oxygen gas pipe 3, so that they cannot be overlooked as a warning signal. The movement of the pins 21 can be used to activate further signal systems 30 in order to provide additional indications of this movement optically and/or acoustically.

This invention relates to a safety valve for a pressurised gas cylinder, the valve comprising: (a) a housing comprising a proximal end and a distal end, the housing comprising a conduit which extends through the housing from an inlet at the proximal end to one or more outlets at the distal end, the inlet being connectable to a gas cylinder so that it is capable of providing fluid communication between the conduit and the gas cylinder; (b) a closure member within the conduit which is movable from a closed position in which it substantially seals the inlet to an open position which provides fluid communication through the conduit from the inlet to the one or more outlets at the distal end of the housing; and (c) a thermal release element within the conduit in the form of a fluid-filled glass bulb comprising a first end which abuts a stop on the housing and an opposing second end which abuts a distal side of the closure member in order to hold the closure member in the closed position.

A valve assembly for controlling the release or delivery of a fire suppression medium from a vessel, the assembly comprising an inlet connectable to a pressurised vessel, an outlet connectable to a delivery device, a valve operable to selectively open or close fluid communication between the inlet and the outlet, an opening device for moving the valve from a closed condition to an open condition, first and second actuators and an environmental triggering device, wherein the opening device is operable, in use, remotely by the first actuator or manually by the second actuator or automatically by the environmental triggering device. A fire suppression system employing the above-described valve and a vehicle including the fire suppression system also form a part of this invention.

One or more techniques and/or systems are disclosed for interrupting fluid flow when experiencing fuel leaking conditions, such as an out of specification connection between the fuel source and a device utilizing the fluid. A distal end of a valve body has interfaces with at least a portion of a connection to a fluid supply; and a proximal end interfaces with at least a portion of a fuel intake. An internal passage runs between the proximal end and distal ends of. A displacement member in the internal passage comprises a distal portion that extends out of the valve to engage a valve to the fuel supply. A retention cap selectably engaged with the valve body can comprise a material that deforms under force at a predetermined temperature, resulting in a release of the displacement member under a biasing force form a biasing component between the cap and displacement member.

A fluid supply assembly having a conduit through which a fluid may be supplied. A thermal shut-off may be provided to control the supply of fluid through the conduit in response to an environmental temperature condition.

A fire protection sprinkler is provided, including a body having an output orifice, a closure element or seal cap to seal a flow of fluid from the output orifice, and a thermally-responsive element positioned to releasably retain the seal cap. A clip, having a first portion and a second portion, is provided, the first portion being engaged with the closure element, and the second portion being in contact with the sprinkler body such that upon actuation of the fire protection sprinkler, the closure element rotates about a pre-determined axis and moves away from the sprinkler body to permit flow of fluid from the output orifice. In particular, the portion of the sprinkler body which the clip contacts is a detent provided on the wrench boss of the sprinkler.

A nuclear plant includes a nuclear reactor, a containment structure that at least partially defines a containment environment of the nuclear reactor, and a passive containment cooling system that causes coolant fluid to flow downwards from a coolant reservoir to a bottom of a coolant channel coupled to the containment structure and rise through the coolant channel toward the coolant reservoir due to absorbing heat from the nuclear reactor. A check valve assembly, in fluid communication with the coolant reservoir, selectively enables one-way flow of a containment fluid from the containment environment to the coolant reservoir, based on a pressure at an inlet being equal to or greater than a threshold magnitude. A fusible plug, in fluid communication with the coolant reservoir at a bottom vertical depth below the bottom of the coolant reservoir, enables coolant fluid to flow into the containment structure based on at least partially melting.
