First Claim
1. A system comprising:
- a distribution boom;
a first pump device configured to provide a flow stream of a carrier substance for the distribution boo;
a second pump device configured to supply a chemical substance into the flow stream of the carrier substance; and
a control module,wherein the distribution boom includes a plurality of boom sections, wherein a boom section includes;
one or more dispensers;
a mixing device configured to provide an initial combination of chemical and carrier substance to the one or more dispensers; and
a control valve configured to supply the chemical substance to the mixing device, wherein the control module is configured to individually duty cycle on and off times of the control valves of the plurality of boom sections to control a rate of supply of the chemical substance to individually adjust a combination of carrier and chemical independently for each boom section.

Abstract
A system comprises a distribution boom, a first pump device configured to provide a flow stream of a carrier substance for the distribution boom, a second pump device configured to supply a chemical substance into the flow stream of the carrier substance, and a control module. The distribution boom includes a plurality of boom sections. A boom section includes one or more dispensers, a mixing device configured to provide a combination of chemical and carrier to the one or more dispensers, and a control valve configured to supply the chemical substance to the mixing device. The control module is configured to individually control a rate of supply of the chemical substance to the boom section by the control valve.

12. A method comprising:
-
providing a flow stream of a carrier substance in a distribution boom using a first pump device, wherein the flow stream is provided from a storage container configured to store the carrier substance to a plurality of boom sections of the distribution boom; adding a chemical substance into the flow stream of the carrier substance at the plurality of boom sections via a mixing device configured to provide an initial combination of chemical and carrier substance to the plurality boom sections; and using a control valve configured to supply the chemical substance to the mixing device to adjust a rate at which the chemical substance is added to a first boom section independently from a rate at which the chemical substance is added to a second boom section by independently duty cycling on and off tires of the control valves of the first and second boom sections. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. An apparatus comprising:
-
means for providing a flow stream of a carrier substance in a distribution boom, wherein the flow stream is provided from a storage container of the carrier substance to a plurality of boom sections of the distribution boom; a mixing device configured to provide initial combination of a chemical substance and carrier substance to the plurality of boom sections; a plurality of control valves for the plurality of boom sections, wherein the control valves are configured to supply the chemical substance into the mixing device to mix with the flow stream of the carrier substance at the plurality of boom sections; and means for independently duty cycling on and off times of the control valves of a first boom section and a second boom section to adjust a rate at which the chemical substance is added to the first boom section independently from a rate at which the chemical substance is added to the second boom section to adjust a combination of carrier and chemical independently for the first and second boom sections. - View Dependent Claims (20)
