摘要： A device for the recovery of dry chemicals found in powdered form for fire extinguishers utilizing a container having first and second openings. A conduit permits the powder material to enter the container through the first opening. Another conduit permits the material to exit the second opening into the fire extinguisher. Lumping is prevented by the use of screens and the like within the container. As the material flows through the second opening of the container, air in the fire extinguisher is conveyed through the first opening in the container.

摘要： This invention relates to systems for clearing smoke from buildings when a fire occurs therein. Smoke detectors are provided in communal units in the building and means are provided for maintaining the pressure in accommodation units of the building above that in the communal units under normal conditions, so that there is a flow of air from the accommodation units to the communal units through the cracks in the doorways separating the accommodation units from the communal units. This flow of air ensures that, if a fire occurs in any one of the accommodation units, smoke will be carried into one of the communal units where it will be detected by one of the smoke detectors. When smoke is detected, conditions are reversed, so that the pressure in the communal units is maintained above that in the accommodation units. As a result, there will be a flow of air from the communal units to the accommodation units, once again through the cracks in the doorways. This flow of air will prevent further smoke from entering the communal units from the accommodation unit in which the fire has occurred, and will ensure that the communal units remain free of smoke to provide a means of escape for the occupants of the accommodation units.
