Abstract: A garden sprayer for dispensing pressurized liquids has a pressure vessel mounted within a liquid reservoir container. The pressure vessel carries a diaphragm pump which is detachable as a complete unit and which extends from the container for connection to a pivoted actuating lever that is fulcrumed on the container. The diaphragm, which is directly driven by the pivoted lever, is guided in position and orientation by a guide piston fixed to the diaphragm and slidably guided within the pumping chamber. A pair of input and output check valves, mounted at the end of the pump, permit liquid from the container to be drawn into the pumping chamber and to be forced from the pumping chamber into the pressure vessel. A manually controlled valve on a spray nozzle, which is connected to the pressure vessel, controls pressurized discharge of liquid.

Abstract: A method for spraying pesticides, herbicides or the like in a moving path from above includes extending a support cable across and over the area to be sprayed and tensioning the cable between two vehicles, one on each side of the area to be sprayed. One or more material spraying nozzles or outlets are supported on the cable and fed by a material-delivering conduit also supported on the cable and connected to a source of material supply on one of the vehicles. The cable is tensioned to a preselected tension sufficient to limit sag in the cable, and tension in maintained substantially constant as the two vehicles are advanced forward with the cable and spray nozzle over the path to be sprayed, irrespective of convergence and divergence of the two vehicles. Constant tension is maintained by a hydraulic motor driving a cable storage reel at constant force.

Abstract: Air is detected from opposing ends of a trough-like continuous contour which defines a guide path for the two opposing streams. The air streams will be attached to flow along the trough and where the oppositely directed streams impact or impinge upon each other, they will be deflected normal to their path and the two combined streams will be projected or directed perpendicularly outwardly from the trough in the form of a fan-shaped jet. By controlling the velocity of the two opposing jets, the point of impact or impingement of the two jets can be moved along the trough with the trough defining the path of movement of the point or virtual outlet of outward projection of the combined jets. In preferred embodiments, the defrost and heating and air conditioning outlets for automobiles incorporate the invention so as to avoid protrusions and provide a continuous clean and unbroken appearance.
