| 101 | Thermal fog generator | US502505 | 1983-06-09 | US4512515A | 1985-04-23 | William L. Tenney |
| A thermal fog generator having an internal combustion engine rotating a blower to discharge a continuous stream of air through a tube into the atmosphere. The hot exhaust gas from the engine is directed to an enclosed muffler and exhaust pipe into the air moving through the tube. A liquid formulation stored in a container is delivered to the muffler. The hot exhaust gas in the muffler atomizes and vaporizes the liquid formulation and carries the atomized and vaporized liquid formulation to the air moving in the tube. The cool air condenses the vaporized liquid formulation to produce a fog. A hand-operated control is used to regulate the supply of engine crankcase gases under pressure derived from the engine crankcase to the container. The control includes a valve unit operable to bypass the crankcase gases under pressure from the engine to the atmosphere and vent the gases under pressure from the container to promptly terminate the flow of liquid formulation to the muffler. | ||||||
| 102 | Technique for heating an agricultural area | US892649 | 1978-04-03 | US4216614A | 1980-08-12 | William C. Triplett |
| There is disclosed a system for heating the atmosphere adjacent a ground surface in an agricultural area as well as the process and apparatus for constructing the system. The system comprises an elongate heat distributing structure which extends through the cultivated area and means for circulating a relatively warm fluid through the heat distributing structure. The heat distributing structure includes a plastic shell member disposed in an upwardly concave configuration having a plurality of imperforate wall conduits bonded thereto. The shell member is filled with sand, crushed rock or gravel to provide a heat sink. The top of the plastic shell member is covered with an asphaltic material which acts to close the top of the heat distributing structure and radiate heat to the atmosphere in the cultivated area. The apparatus for laying the heat distributing structure comprises a tracked vehicle having a plow thereon for excavating a shallow furrow in the earth, a reel containing the spooled shell member, a trough on which the shell member runs during unreeling, means for delivering crushed rock into the top of the shell member and means for applying the asphaltic material to the top of the shell member. | ||||||

| 104 | Heater for orchards and the like | US600453 | 1975-07-30 | US3982524A | 1976-09-28 | Richard E. Diggs |
| A heater for orchards and the like includes a stackable, heat transmitting, upright housing. A fuel burner is supported in the housing near a lower end thereof and includes an air inlet chamber having an annular, upwardly directed outlet at the periphery of a fuel dispersing plate and air flows through the outlet under pressure in an upward direction and with a spinning motion to vaporize fuel and convey it to a combustion zone for turbulent, substantially pollution-free combustion of the fuel. The burner may also be used with conventional orchard heater housings to provide substantially pollution-free heating of orchards and the like. | ||||||
| 105 | Orchard heater | US33051273 | 1973-02-08 | US3857671A | 1974-12-31 | COX W |
| A relatively inexpensive, effective orchard heater capable of being used without significantly causing atmospheric pollution can be constructed utilizing an elongated stack, the upper end of which is open and the bottom end of which is closed, with a cover provided with a centrally located opening. A carburetor plate is located so as to extend across the interior of the stack between the ends of the stack and is located so as to be spaced from the interior of the stack. First air holes are located in the stack between the carburetor plate and the upper end of the stack and second air holes are located in the stack away from its lower end beneath the carburetor plate. The openings and the holes are dimensioned with reference to the amount of fuel to be used in the heater so as to permit partial combustion of the fuel beneath the carburetor plate. Such partial combustion causes heating of the stack and of this plate which tends to vaporize the unburned fuel beneath the carburetor plate around it so as to draw in air through the air holes to a sufficient extent so that a flame is created above the upper end of the stack.

| 107 | Heater | US29129972 | 1972-09-22 | US3814574A | 1974-06-04 | DARLEY R |
| A heater having primary and secondary fire combustion chambers, the primary chamber being formed by a bowl and the secondary chamber being formed by a stack vertically disposed atop the bowl and communicating with the primary combustion chamber. A nozzle assembly is provided for spraying fuel into the primary chamber, and the stack has secondary fire draft holes therein. The primary combustion chamber has a plurality of primary draft or air entry holes in the upper surface thereof, and a fire stabilizing device in the form of an arcuate shield is disposed between the primary draft holes and the nozzle assembly. The shield deflects the incoming air about the inside periphery of the primary chamber for providing thorough mixing of the fuel and air, the burning of a portion of the mixture in the primary combustion chamber. Ultimate complete combustion occurs in the secondary combustion chamber. The heater may be used as a pipeline heater in an automated system with a plurality of similar heaters.

| A natural-draft space heater, having a conventional fuel jet which produces a hollow fuel cone when fed with pressurized fuel oil or compressed gas. The jet is spaced below a base plate having a central hole therethrough and is disposed centrally within the hole with the axis of the fuel cone perpendicular to the base plate. The heater also comprises an upright chimney, having a preferred height of 24 inches, which is disposed on the base plate, and a dispersal plate, of the same size as the central hole, spaced thereabove, aligned therewith, and spaced therefrom so that it intercepts the tulip-shaped hollow cone to produce a wet ring (before ignition) about 1/8 inch to 1/16 inch in thickness adjacent to its circular edge. The preferred diameter of the dispersal plate is about 3 1/2 inches, and the preferred interplate spacing is about 3 inches. The intercepted cone is reflected outwardly and downwardly and may be ignited with a 6-volt ignition device attached to the base plate. After ignition, the deflected flame extends radially from the circular edge but does not exist between the orifice and the circular edge. With fuel oil at 70 psig, the flame is about 4 inches long; with pressurized gas at 0.5 psig, the flame is about 3 inches long, 0.5 gallons per hour of each fuel being burned at these conditions. Tested particulate emissions were 0.2 grams per minute for diesel fuel and 0.005 grams per minute for propane gas at these conditions.
