    摘要: Fire-fighting apparatus including a main cistern to be suspended from a flying machine and flown to fires. One or more openings in the bottom readily admit water to fill the cistern and are then closed by a gate until the cistern has been flown to the fire. A second cistern contains an additive to be dispensed into the water to help fight the fire. The dispensing apparatus includes a cylinder, a piston in the cylinder, and a piston driver connected to the suspension apparatus. A draw-spring pulls the piston toward the bottom of the water cistern, and the gate is connected to the piston to be closed to seal the cistern when the piston is drawn toward the bottom of the cylinder. A first conduit and first valve control the transfer of the additive from the second cistern to the cylinder when the piston is moving downwardly. A controllable valve and second conduit allow the additive to be transferred from the cylinder to the water cistern when the apparatus reaches the fire area. Resulting upward movement of the piston opens the gate and dispenses water with the additive onto the fire. An additional conduit allows excess additive to be transferred from the cylinder back to the second cistern after enough additive has been dispensed into the water cistern for one load.

    摘要: A plant for de-icing especially surfaces of aeroplanes, comprising the use of at least two sources (10, 12) of liquid media that are different from each other and capable of being sprayed separately or as a mixture, comprising a number of positive liquid pumps (16, 22) corresponding to the number of media, which pumps all have the same capacity or a predetermined interrelated capacity ratio and terminate in a common spray pipe (24). The connection of the liquid pumps to the sources includes at least one of the sources to at least one of the liquid pumps. In a hydraulic system comprising hydraulic motors (56, 52) for driving the liquid pumps (16, 22) at least two of motors are connected to a common hydraulic pressure pump (32) controlled by way of pressure compensation (33) to work with at least two pressure stages subject to a ratio corresponding to that of the capacity of at least one liquid pump to the total capacity of both liquid pumps. In such a plant the compostion of the spray liquid to be dispensed is determined solely by the capacity of the liquid pumps, thereby eliminating any throttling effects which may cause the de-icing medium to coagulate.

    摘要: A spray can for resin paints under pressure incorporates a secondary container in its interior for holding a catalyst. A spray means including a spray valve is received on one end of the cam and includes an elongated tube extending into the can. The secondary container includes inertia means in the form of a weight. The arrangement is such that shaking of the can causes the weight to shatter the secondary container thereby placing the catalyst and resin in communication with each other. Mixing of the ingredients can thus take place just prior to a spraying operation, the mixture passing up through the tube and out the spray means when the spray valve is opened.
