Abstract
Abstract Irrigation of plants and control of the temperature and humidity of the air in the vicinity of plants is provided through the same water supply system. Nozzles located adjacent the plants along a water supply conduit are shaped to produce a small stream of water at low water pressure for irrigating the plants and to produce a fine spray or mist of water at high water pressure for temperature and humidity control. The pressure of the water which is supplied to the system is controlled to cause either irrigation or temperature and humidity control.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
113 words
The method of selectively irrigating and controlling the temperature and humidity of plants through a water irrigation system for supplying water to orifices adjacent each plant from a water pressure control means coupled to a water supply, the water irrigation system containing a multiplicity of intercommunicating orifices comprising supplying water at a low pressure from the water pressure control means to the multiplicity of intercommunicating orifices of the irrigation system to the plants in a small stream to irrigate the plants, and alternatively supplying water at a high pressure to the multiplicity of intercommunicating orifices of the irrigation system to produce fine sprays Of water adjacent the plants for temperature and humidity control.
Claim 2
Independent Claim
113 words
The method of selectively irrigating and controlling the temperature and humidity of plants through a water irrigation system for supplying water to orifices adjacent each plant from a water pressure control means coupled to a water supply, the water irrigation system containing a multiplicity of intercommunicating orifices comprising supplying water at a low pressure from the water pressure control means to the multiplicity of intercommunicating orifices of the irrigation system to the plants in a small stream to irrigate the plants, and alternatively supplying water at a high pressure to the multiplicity of intercommunicating orifices of the irrigation system to produce fine sprays Of water adjacent the plants for temperature and humidity control.
Claim 3
Independent Claim
108 words
The method of irrigating and controlling temperature through a water irrigation system coupled to a water supply through water pressure control means and having a multiplicity of intercommunicating nozzle means located along the system and pointed upwardly and shaped to produce a small stream of water at low water pressure and to produce a fine spray at high pressure, comprising reducing, at the water pressure control means, the pressure of the water in the irrigation system to a low pressure to selectively cause irrigation or switching, at the water pressure control means, the pressure of the water in the irrigation system to a high pressure to control temperature.
Claim 4
Independent Claim
108 words
The method of irrigating and controlling temperature through a water irrigation system coupled to a water supply through water pressure control means and having a multiplicity of intercommunicating nozzle means located along the system and pointed upwardly and shaped to produce a small stream of water at low water pressure and to produce a fine spray at high pressure, comprising reducing, at the water pressure control means, the pressure of the water in the irrigation system to a low pressure to selectively cause irrigation or switching, at the water pressure control means, the pressure of the water in the irrigation system to a high pressure to control temperature.
Claim 5
Independent Claim
123 words
The method of irrigating and controlling temperature of plants through a water irrigation system coupled by water pressure control means to a water supply which comprises causing the irrigation system to simultaneously emit a small stream of water from each of a multiplicity of intercommunicating orifices at a low pressure to the ground adjacent the plants for irrigation by reducing water pressure to the water irrigation system at the water pressure control means, and alternatively causing the irrigation system to simultaneously emit a fine spray of water from each of the multiplicity of intercommunicating orifices to the air adjacent the plants at high water pressure by increasing water pressure to the water irrigation system at the water pressure control means for temperature control.
Claim 6
Independent Claim
123 words
The method of irrigating and controlling temperature of plants through a water irrigation system coupled by water pressure control means to a water supply which comprises causing the irrigation system to simultaneously emit a small stream of water from each of a multiplicity of intercommunicating orifices at a low pressure to the ground adjacent the plants for irrigation by reducing water pressure to the water irrigation system at the water pressure control means, and alternatively causing the irrigation system to simultaneously emit a fine spray of water from each of the multiplicity of intercommunicating orifices to the air adjacent the plants at high water pressure by increasing water pressure to the water irrigation system at the water pressure control means for temperature control.
Claim 7
Independent Claim
94 words
The method of irrigating and controlling temperature of plants through a water irrigation system comprising providing from a water pressure control means coupled to a water supply and the water irrigation system, high pressure hollow cone-shaped fine sprays of water at a multiplicity of locations adjacent plants to be protected from low temperature damage, or providing water at a low pressure from the water pressure control means to the system in small streams of water at each of said locations for irrigation to selectively cause irrigation or temperature control of a multiplicity of plants.
Claim 8
Independent Claim
94 words
The method of irrigating and controlling temperature of plants through a water irrigation system comprising providing from a water pressure control means coupled to a water supply and the water irrigation system, high pressure hollow cone-shaped fine sprays of water at a multiplicity of locations adjacent plants to be protected from low temperature damage, or providing water at a low pressure from the water pressure control means to the system in small streams of water at each of said locations for irrigation to selectively cause irrigation or temperature control of a multiplicity of plants.
Claim 9
Independent Claim
111 words
The method of irrigating and controlling temperature through a water irrigation system comprising producing in response to high pressure in the system a hollow cone-shaped fine spray at locations spaced from one another a distance equal to or greater than the maximum horizontal dimension of the cone-shaped spray so as to provide effective temperature control with a small amount of water and thereby avoid applying excessive water to the area being controlled, producing in response to low pressure in the system a small stream of water at each of said locations for irrigation, and controlling the pressure of the water in the irrigation system to selectively cause irrigation or temperature control.
Claim 10
Independent Claim
111 words
The method of irrigating and controlling temperature through a water irrigation system comprising producing in response to high pressure in the system a hollow cone-shaped fine spray at locations spaced from one another a distance equal to or greater than the maximum horizontal dimension of the cone-shaped spray so as to provide effective temperature control with a small amount of water and thereby avoid applying excessive water to the area being controlled, producing in response to low pressure in the system a small stream of water at each of said locations for irrigation, and controlling the pressure of the water in the irrigation system to selectively cause irrigation or temperature control.
