  • Patent number: 4600147
    Abstract: Apparatus is provided for release of liquid propane from the holding chamber of a cloud-seeding rocket. The invention includes a liquid propane-filled bag within the chamber to expand and apply continuous pressure on the liquid propane in the chamber as it exits the chamber to be used for cloud-seeding purposes. A second aspect of the invention has a valve mechanism triggered by the ignition of a fuse to release a lever action. Admixing of small amounts of other gaseous compounds with the liquid propane enhances the ice nucleation of the liquid propane as it is discharged from the rocket.

  • Patent number: 4573636
    Abstract: An improved method of and apparatus for making artificial snow. The snow making machine disclosed for practicing the invention includes a ducted fan within a housing for generating a substantially unidirectional, high volume air current over the area to be deposited with snow. High velocity water sprays are injected into the air current from above and below the air current via a plurality of nozzles connected to an annular water manifold circumferentially disposed around the discharge end of the housing. Nucleated ice crystals are also injected into the air current by a high velocity vapor spray emitted from a pair of seeder nozzles disposed at the center of the housing. The vapor spray is comprised of a mixture of water and compressed air which is vaporized in a venturi-type expansion chamber prior to emission through the seeder nozzles.

  • Patent number: 4572438
    Abstract: A spray gun for airless atomization for electrostatic deposition of a coating material upon a substrate includes a novel dual electrode element having a spring loop portion. The two electrodes are the respective end portions of a single electrode wire, which has its major portion between the electrodes formed into a spiral spring. A tip resistor is provided with a conductive fitting that presents a broad and sturdy bearing surface which abuts the electrode spring portion to thereby directly connect the electrode with a high voltage charging circuit. The electrode spring accommodates spacing variations between the electrode and tip resistor, and provides a continuous electrical connection regardless of the rotational position of the electrode relative to the tip resistor. The dual electrode spring further serves to secure a number of otherwise loose parts of the gun nozzle assembly together, and prevents the parts from falling out and getting lost when the nozzle assembly is removed from the spray gun.

  • Patent number: 4569482
    Abstract: A cleaning apparatus and method is disclosed which utilizes a nozzle generally comprising a cylindrical drum having external and internal air chambers, each of which terminates in a pipe having a rectangular cross-section. One of the pipes has a smaller cross-section than the other, and is disposed within the larger pipe. A high-pressure water pipe is concentrically disposed along the longitudinal axis of the smaller pipe. The space between the two pipes defines a passageway for a stream of compressed air which shapes the stream of water emanating out of the center of the smaller pipe into a jet of water having a bar-shaped cross-section, and a uniform pressure gradient at all points across this cross-section. The smaller pipe is provided with a symmetrical array of apertures for shunting part of the air stream flowing between the two pipes in a radial direction toward the pressurized stream.

  • Patent number: 4569484
    Abstract: A device to atomize and inject a coal slurry in the combustion chamber of an internal combustion engine, and which eliminates the use of a conventional fuel injection pump/nozzle. The injector involves the use of compressed air to atomize and inject the coal slurry and like fuels. In one embodiment, the breaking and atomization of the fuel is achieved with the help of perforated discs and compressed air. In another embodiment, a cone shaped aspirator is used to achieve the breaking and atomization of the fuel. The compressed air protects critical bearing areas of the injector.

  • Patent number: 4566635
    Abstract: A fuel injection nozzle for internal combustion engines, having a valve needle, which at the end of a pre-stroke directly or indirectly opens an auxiliary conduit, by way of which the fuel pressure acts upon a reservoir piston and a pressure shoulder which acts in the closing direction of the valve needle. As a result, the valve needle is temporarily returned to the valve seat and the closing pressure is notably increased. The subsequent primary injection phase is initiated at a correspondingly higher pressure, and the higher closing pressure continues effective until the end of the injection event, thereby bringing about an exact closure of the valve.

  • Patent number: 4565323
    Abstract: Improvements in an oscillating sprinkler having an improved discharge of fluid wherein the fluid being discharged enters two side by side curved chambers and is split into two separate streams. The spring controlling the oscillation of the sprinkler is centered on the impact arm of the sprinkler by a spring retainer and a boss on the arm itself so as to provide a smooth transition for the water and disperse it evenly with less operating pressure. The arm may have a removable reactor spoon portion so that the spoon portion can be quickly and easily replaced, if desired.

  • Patent number: 4562962
    Abstract: A sprinkler or water circulating system having a selected number of sprinkler heads, bubblers or the like, each having an associated valve mechanism adapted to effect valve closure upon displacement of the sprinkler head, bubbler, etc., during water flow thereby preventing loss of sprinkler effect and fluid. A normally open spring loaded valve is positioned in a conduit to which the sprinkler head or the like is attached. A stem or rod is positioned in engagement between sprinkler head and valve so that upon displacement the stem may be broken off if of frangible material, or otherwise displaced and the valve is urged into closed position. Upon replacement of the sprinkler head or the like in proper position the rod is replaced to maintain the valve in open position.

  • Patent number: 4562963
    Abstract: A garden sprinkler is provided and consists of a hollow tubular frame in an endless closed path that has a first set of inwardly facing apertures along one portion of the frame forming a first spray tube and a second set of inwardly facing apertures along an opposite portion of the frame forming a second spray tube and a device for removably connecting a standard garden hose to the hollow tubular frame. When the hollow tubular frame is placed on a ground surface and water pressure through the garden hose is low the first spray tube and the second spray tube will spray water inside the endless closed path area. When water pressure through the garden hose is high the first spray tube and the second spray tube will overshoot the endless closed path area and spray water to other areas of the ground surface.

  • Patent number: 4560107
    Abstract: Aerial spraying apparatus includes two sets of nozzles located at spaced locations on an aircraft. Each nozzle has an electrode associated with it to induce a charge on the cloud of droplets issuing from the nozzle. A high potential is maintained on each electrode by a power pack that induces an equal and opposite potential on the electrodes of each set. By virtue of the opposed polarity of the electrodes, the aircraft is maintained at a neutral potential. To prevent a potential being imposed due to spray being deposited on the electrodes, a pair of corona needles are provided to establish a leakage current and maintain the electrodes at the required potential. This prevents the system becoming imbalanced and a potential being established on the aircraft.
