Oct 24, 2014

Appl. No.:

14/523098

Inventors:

- Sioux Falls SD, US
Patrick A. Hansen - Tea SD, US
Warren L. Thompson - Baltic SD, US
Nicholas O. Michael - Sioux Falls SD, US

International Classification:

F28F 1/12
F28F 13/12

US Classification:

1651091, 165181

Abstract:

A heat exchange unit for a heat exchanger system includes a heat exchange tube. The heat exchange tube including a heat exchange tube inlet and one or more heat exchange fins coupled along the heat exchange tube. The heat exchange tube extends from the heat exchange tube inlet to a refrigerant return. A heat exchange jacket is interposed between the heat exchange tube and a unit housing. The heat exchange jacket includes a jacket passage in communication with the refrigerant return. A first product passage extends from the product inlet to a product return. The heat exchange fins turbulate agricultural product in the first product passage while heat is transferred from the agricultural product to refrigerant in one or more of the heat exchange tube or the heat exchange jacket. Heat is transferred from the agricultural product to the refrigerant through the heat exchange jacket in the second product passage.

International Classification:

A01C 23/00

US Classification:

239 11, 239 71

Abstract:

This document discusses, among other things, apparatus and methods for a multi-section applicator having variable-rate sections. In an example, an apparatus can include a flow meter to provide a substance to plurality of sections, and an applicator controller including memory configured to store a coverage map of the substance. In certain examples, each section can include a metering device configured to receive a flow command and to provide a flow of the substance to a manifold using the flow command. In certain examples, the applicator controller can be configured to receive speed information and position information of the apparatus, to receive the flow rate information, to determine application rate information of the substance for each section using the speed and position information, and the coverage map, and to provide the flow command to each metering device using the application rate and flow rate information.

International Classification:

B05B 1/30

US Classification:

239 11, 239156

Abstract:

This document discusses, among other things, apparatus and methods for a multi-section applicator having variable-rate sections. In an example, an apparatus can include at least one distribution manifold, a user interface, and an applicator controller. The at least one distribution manifold distributes a substance and can include an inlet port configured to receive the substance, a plurality of outlet ports, one or more sensors located at an outlet port, a controllable valve that supplies the substance to the inlet port. The applicator controller measures a value of the distribution parameter using the sensor signal produced by the at least one sensor of an outlet port, detects when the measured value differs from a specified target value by more than a specified error threshold value, and presents an indication, using the user interface, that the measured value differs from the target value according to the detection.

US Classification:

700283

Abstract:

This document discusses, among other things, apparatus and methods for applying liquid substances, including gaseous/liquid substances using an adjustable pump control system. In certain examples, an example liquid application apparatus can include, a metering device to provide a flow of a first substance, one or more distribution branches to receive the flow of the first substance and release the first substance through an orifice of one of the one or more distribution branches; and an applicator controller including memory configured to store an application map, the applicator controller configured to receive speed information and position information of the apparatus, to determine application rate information of the first substance for each distribution branch using the speed information, the position information and the application map, and to provide a flow command to the metering device using the application rate information.
