Abstract: An original method and products are described for fire quenching in all substrata such as forests, cultivated areas, city areas, industrial units, transport vehicles, etc. Aqueous suspensions of fire quenching special products contain endomolecularly water up to 300 g water/g of polymeric product, and the water is kept very strongly so that pressure is needed to take the water out. These products are used in quantities of 1-3%, and to the quenching water are added complimentary other products such as detergents, emulsifiers, adhesion promoters, and inorganic products such as carbonates, sulfates silicones etc. Quenching fires utilizes the solution containing these or a selection of these products, and the solution is thrown in the fire edges to rapidly extinguish the fires, because the water contained in the special organic products is liberated in the fire edges, where quenching immediately occurs.

Abstract: The invention is a lawn sprinkler head protector that is placed around the sprinkler head and pressed into the grass and/or soil in which the sprinkler head is located.

Abstract: A system for deployment of traction enhancing agents uses an infrared detecting sensor to receive ambient IR from a roadway, whereby the road surface temperature is determined. The determined temperature is supplied to a traction enhancing agent deployment controller, so that the amount and selection of particular agents can be governed based on the particular road surface temperature. Variations are thereby accommodated, so the most appropriate agent or agents in an appropriate combination and density can be applied.

Abstract: The metering valve has a shutter for a discharge conduit, and an electromagnet for controlling an armature disconnected from the respective stem and sliding along the stem by means of a sleeve. The stem is guided by a fixed sleeve and is pushed by a first spring to hold the shutter in the closed position, and a second spring keeps a shoulder of the armature resting axially against a C-shaped ring fitted to the stem. To reduce the overtravel of the armature with respect to the travel of the stem to move the shutter into the closed position, and to damp oscillation of the armature, provision is made, between the two sleeves, for a bush of calibrated thickness, which slides along the stem and is such as to form a small axial clearance with the sleeves.

Abstract: Fluid and air nozzle assemblies are capable of propelling streams of a cleaning fluid and air mixture onto a vehicle headlight. These nozzle assemblies are mounted on a vehicle adjacent to the headlights and positioned such that liquid and air jets from the nozzles intersect prior to engaging the headlight to form a spray mixture that cleans the headlight. These nozzle assemblies have an adjustment feature for the purpose of aiming the fluid-air spray toward the headlight lens. The nozzle assemblies are associated with a control valve capable of connection in a pressurized air system on the vehicle and in the pressurized washer system for the windshield wipers and also capable of automatically directing liquid from the vehicle washer system and pressurized air on the vehicle to the liquid and air nozzles to form a headlight cleaning function upon manual activation of the pressurized windshield washer system of the vehicle.

Abstract: The present invention provides a fluid discharging apparatus that delivers fluid in a substantially uniform distribution. The movement of the apparatus is a wobbling motion, preferably combined with some rotational motion. The wobbling motion is generated by disposing a wobble inducing member or wobble turbine in the path of the fluid supply. The water flowing over the wobble turbine causes the turbine to wobble. In certain embodiments, the wobbling turbine then causes the body or housing to wobble.
