An automatic fire extinguishing system includes a canister having a central axis, an outlet port disposed on the canister, a dip tube disposed in the canister about the central axis and in partial fluid communication with the canister and coupled to the outlet port, a propellant gas mixture of COand Ndisposed within the canister and a gaseous fire suppression agent disposed in the canister.

N2/CO2 fire extinguishing system propellant gas mixture

An automatic fire extinguishing system includes a canister having a central axis, an outlet port disposed on the canister, a dip tube disposed in the canister about the central axis and in partial fluid communication with the canister and coupled to the outlet port, a propellant gas mixture disposed within the canister; and a gaseous fire suppression agent disposed in the canister, wherein a diameter of the outlet port is sized relative to a pressure of the propellant gas mixture.

Automatic fire extinguishing system having outlet dimensions sized relative to propellant gas pressure

An automatic fire extinguishing system includes a canister having a central axis, an outlet port disposed on the canister, a dip tube having dip tube side holes and inlet openings, and disposed in the canister about the central axis and in partial fluid communication with the canister and coupled to the outlet port, a propellant gas mixture disposed within the canister and a gaseous fire suppression agent disposed in the canister.

Automatic fire extinguishing system with internal dip tube

An automatic fire extinguishing system includes a canister having a central axis, an outlet port disposed on the canister, a dip tube disposed in the canister about the central axis and in partial fluid communication with the canister and coupled to the outlet port, a propellant gas mixture disposed within the canister, a gaseous fire suppression agent disposed in the canister and a dry powder fire suppression agent disposed in the canister.

A fire suppression cylinder includes a valve at an outlet of a canister, and a control for the valve. The canister receives a liquid suppressor agent and a pressurized gas. A feature within a portion of the canister will receive the liquid suppressor agent. The feature increases the formation of gas bubbles within the liquid suppressor agent.

Fire suppressor cylinders with enhanced bubble production

A sensor apparatus includes a metal oxide semiconductor ('MOS') sensor with a gas-sensing surface normally having a first sensitivity to a first species of flammable gas and a second sensitivity to a second, different species of flammable gas. A selective sensitivity-enhancement layer is disposed on the gas-sensing surface such that the first sensitivity becomes increased and the second sensitivity remains substantially unchanged.

Sensor apparatus and method therefor

A sensor apparatus includes a metal oxide semiconductor sensor and a housing having an internal chamber in which the sensor is disposed. The housing includes at least one window for the ingress of a gas into the internal chamber from an atmosphere exterior to the housing. A gas-selective barrier is disposed across the at least one window.
