摘要:
Fire-extinguishing compositions of low ozone depletion potential comprise dry particles of ammonium bromide coated with an abherent such as zinc stearate to improve flowability. The coated particles enhance the fire-extinguishing properties of chlorofluorocarbons and halogenated paraffins having low ozone depletion properties, when dispersed therein.

The disclosure herein describes a system for extinguishing fires which consists in first maintaining a supply of liquid fire extinguishing medium in a tank under a pressure cushion of expellant material; the medium is delivered upon detection of a hazard by opening a normally closed valve in a delivery line connected to the tank; this operation triggers a sequential operation of a plurality of groups of expellant containers which causes additional expellant material to be delivered to the tank to maintain therein a given pressure so as to effect quick and total evacuation of the fire extinguishing medium from the tank to the hazard.
摘要:
A method and apparatus to prevent ignition or inhibit reignition of a fuel issuing from a conduit in which an extinguishing liquid is injected into the fuel upstream of the conduit outlet and a turbulence is established by the injection and/or by the conduit cross-section which intimately mixes the fuel and liquid throughout the cross-section of the fuel upstream of the outlet.
摘要:
The application of ablative water in combating fire is improved by wetting the surfaces of the combustible materials to be protected with water containing a surfactant prior to the application of ablative water to such surfaces in order that the subsequently applied ablative water readily penetrates the combustible material down to where the fire is in order that the ablative water be available where it is required.
摘要:
When dumping grain from a truck box through the tailgate opening, grain lodges in the corners upon each side of the tailgate opening and the operator normally has to stand on the auger or the like in order to reach over the tailgate with a shovel and is therefore at risk due to the danger of slippage with the danger perhaps of coming into contact with the rotating discharge auger assembly. The present device consists of a handle and an arcuately curved rake blade secured at one end with the major portion of the blade extending on one side thereof. This can be engaged within the tailgate opening and reaches into each back corner of the box thus enabling the operator to pull the lodged grain towards the opening readily and easily.
摘要:
A fire extinguisher system using liquid-ballast tires of a vehicle, such as a tractor or log skidder. The tire has a fire retardant liquid, and it may be water, and it has several valves spaced therearound. A gas supply can be attached to one of the valves to force the liquid from the tire, and a hose can be attached to another one of the valves for directing the evacuating liquid from the tire and toward the fire.

A new fire extinguishing composition in the form of a high aqueous content thick viscous material which forms an effective water blanket when applied or sprayed on horizontal or vertical surfaces and the like.
