Abstract: A disaster preventive apparatus has a gas cylinder support to which the head of a gas cylinder filled with CO.sub.2 gas is fixed, and the support is screwed in a top cover. When a bottom cover is turned by one hand while the top cover being held by the other hand after a lock pin, which locks the top cover and the gas cylinder support in a nonrotatable manner, is pulled out, the gas cylinder can be moved in the axial direction to the trigger side while being turned with a small force. Since the trigger is formed into a special shape such that the tip end face thereof and the outer peripheral surface of trigger tip end portion make an obtuse angle, a seal plate can be broken easily. Also, the broken portion of the seal plate is not separated from the seal plate and is bent inward in the gas cylinder, so that the ejection of CO.sub.2 gas is not hindered by seal plate chips. There is less possibility of bending and breaking of the trigger.

Abstract: A fire extinguisher for automotive use is provided with the additional capability of sealing and reinflating a flat tire without any wheel removal. The device is charged with a combination fire-extinguishing and tire-sealing composition, and fitted with a removable nozzle for extinguishing fires. To seal and inflate a flat tire, the nozzle is removed, and, in its place, one end of an adaptor hose assembly is attached to the fire extinguisher, and the other end is connected to the tire valve with the wheel rotated to place the puncture or leak at the bottom. Then actuating the device dispenses sealant into the tire while inflating it, after which vehicle movement distributes the sealant and generates heat which accelerates the tire-sealing action and further inflates the tire to a higher pressure, enabling the vehicle to proceed to a service station.

Abstract: A check system for a chemical fire extinguisher utilizes a normally-closed check valve to prevent escape of pressurized chemical during periodic maintenance of a pressure monitoring system, such as a pressure gauge. An actuator member which is disposed within the flow channel of the fire extinguisher system is used to apply a force to the check system whereby a normally-closed check valve is urged to its open state. This open state establishes communication between the interior of the pressurized tank and the pressure monitoring system. Removal, or loosening, of a coupler, or union, which secures the pressure monitoring system to the chemical tank, permits the check valve to return to its normally-closed state. Thus, the pressure monitoring system can be removed and serviced periodically without requiring the pressurized tank to be emptied.
