Abstract: A process and a device for atomization of a liquid extinguishing medium, in which the liquid extinguishing medium and a liquid inert gas are mixed in a mixing unit to form a liquid extinguishing medium mixture. The mixture is conveyed through a conduit to a distributing device such as extinguishing nozzles. As the mixture exits the distributing device the mixture is atomized, forming an aerosol spray for extinguishing a fire within an extinguishing area defined by the aerosol spray. A detector arranged in the extinguishing area for detection of parameters relating to extinguishing of the fire is connected to an evaluation device which in turn is connected to a control valve. The control valve regulates the quantity of liquid inert gas supplied to the mixing unit.

Abstract: A granular material spreader is adapted for towing behind a yard tractor. A frame upports an inverted cone which is sized to contain a supply of granular material for distribution. The bin sweep rod is carried adjacent to the inside surface of the cone, and turns a drive spring. The drive spring drives a helix, which rotates about the bin sweep rod, driving the granular material toward the narrow base of the cone. Should the helix become jammed, the drive spring snaps past the helix, rather than risk damage by forcing its movement. A bin sweep drive wheel is also driven by the revolution of the bin sweep. Movement of the wheel against the an upper portion of the outside surface of the cone moves the bin sweep rod and helix in a circular path about the inside surface of the cone. A valve at the base of the cone allows granular material to drop into a housing which defines slots about portions of its perimeter.

Abstract: Valve, in particular glue valve, having a magnetostrictive actuator (14) for actuating a closure member (15) in consequence of a change in a magnetic field. In order to nullify the effects of uncontrolled changes in length of the actuator (14), in particular in consequence of temperature fluctuations, the actuator (14) is connected to a holder, more specifically a holding block (23), which can be moved with inertia.

Abstract: A hand holdable pump spray system where the pump mechanism is in the hand holdable wand rather than in the liquid container. The wand may be held with one hand while the pump handle is extended with the other hand. This creates a pressure differential which allows liquid to flow from the container into the wand. A biased spring provides force against the liquid so that when a thumb actuated trigger opens the nozzle, the liquid will be ejected. Should all of the liquid not be ejected, there is a liquid return mechanism which opens a check valve and allows the liquid to return to the container through a supply tube connecting the wand and the container.

Abstract: A multifunctional air gun, designed to be operable in a sucking mode, a blowing mode or a sucking and blowing mode, is disclosed. In the air gun, a tubular body has an on/off valve unit in addition to upper and lower openings communicating with each other. A fixed spool is set within the upper opening of the tubular body and connects the air supply tube to an air jet pipe while controlling the flowing direction of compressed air. A vacuum valve unit is set within the lower opening of the tubular body and is assembled with suction and exhaust nozzles at both ends while allowing the two nozzles to communicate with each other. The vacuum valve unit vacuumizes the interior of the two nozzles due to the compressed air. A first control knob is assembled with the fixed spool to control the compressed air for the vacuum valve unit, thus controlling the suction force generated by the compressed air for the vacuum valve unit.

The fuel injection valve is especially suitable for injecting fuel directly into the combustion chamber of a mixture-compressing internal combustion engine with externally supplied ignition.

Abstract: A hydraulically actuated fuel injector includes an injector body that defines a high pressure passage, a low pressure passage, a control passage, a fuel inlet, and a nozzle outlet. The injector body includes upper surface and a lower surface that partially define an armature cavity. The injector body also defines a fluid displacement passage that is separated from the upper surface and the lower surface and extends between the armature cavity and a low pressure area. The fluid displacement passage is positioned and sized such that an amount of oil is always maintained in the armature cavity at least to a level below the fluid displacement passage but above the lower surface. In addition, the fluid displacement passage is sized and positioned to ensure adequate drainage for cold start, yet provide a flow restriction especially at idle conditions to produce sufficient valve damping that a substantial reduction in impact noise occurs.

The fuel injection valve includes a swirl disk downstream from a valve seat, the swirl disk being made of at least one metallic material, having at least two swirl channels opening into a swirl chamber, and in which all layers are adheringly deposited directly one on top of the other by electroplating (multilayer electroplating). A perforated spray disk having an outlet opening shaped so that it directly influences the flow of the fuel exiting through the outlet opening of the swirl disk is arranged directly downstream from the swirl disk. The fuel injection valve is particularly well suited for direct injection of fuel into the combustion chamber of a compressed mixture externally ignited internal combustion engine.

Abstract: An airless sprayer adapted to spray both paint and texture material. The sprayer uses a reciprocating piston that mechanically forces the material to be dispensed out of a charging chamber. The piston is driven by a motor mounted within a motor chamber. A working surface of the piston has a surface area adapted to dispense texture material. The sprayer is gravity fed with an overhead hopper. The sprayer is provided with a detachable overflow member that defines an overflow chamber for capturing texture material that leaks around the piston. This overflow chamber is configured relative to the motor chamber such that material leakage is contained within the overflow chamber and does not reach the motor chamber.

Abstract: A flame spray system employs splatter blocking and automated rod delivery apparatuses. The splatter blocking apparatus includes a barrier member and an actuation mechanism. The barrier member is adapted to be moved between a blocking position in which the barrier member is extended across a spray path from a flame spray gun of a flame spray system preventing travel of particles of fusible material from the flame spray gun to a product being coated and an unblocking position in which the barrier member is displaced from the spray path of the flame spray gun permitting travel of particles fusible material from the flame spray gun to the product being coated. The actuation mechanism is connected to the barrier member and adapted to be selectively actuated to move the barrier member between the blocking and unblocking positions.
