Filed:

Jan 7, 1992

Appl. No.:

7/817699

Inventors:

Neil C. Smith - Fremont NE

Gary Tuma - Blair NE

Assignee:

Concrete Equipment Company - Blair NE

International Classification:

B28C 904

US Classification:

414332

Abstract:

A portable concrete batch plant which may be pulled from one location to another and which may be used either as a transit mix batch plant or a central mix batch plant. The batch plant is mounted on a wheeled frame comprised of a rear frame section and a front frame section removeably secured thereto. The batch plant is transported from one location to another with the rear and front frame sections connected together. If the batch plant is desired to be used as a transit mix plant, the front and rear frame sections remain connected together. If it is desired to use the concrete batch plant as a central mix batch plant, the front and rear frame sections are separated with the front frame section being spaced horizontally and vertically from the rear frame section with an extension conveyor being positioned there between.

Abstract:

A center pivot irrigation system having an elongated concuit assembly with an inner end pivotally connected to a water source at a center pivot and having a plurality of discharge nozzles at spaced intervals along its length has one or more short range and a long range end gun mounted near the outer end of the conduit for irrigating the corner areas of a rectangular or square field. The long range end gun is adjusted to have a spray pattern which extends inwardly to provide water to that area normally irrigated by the sprinklers along the outer section of conduit in addition to an area extending beyond the outer edge of the arc farther than that covered by the short range guns. By turning off sprinklers along a section of conduit, water is diverted to help provide a sufficient pressure and flow rate as is necessary for efficient operation of the long range end gun. The end guns are sequenced on and off by a control system using only one wire to transmit control signals to operate two different ranges of end guns. A switch and diode arrangement produces a series of positive going pulses for one range end gun and a series of negative going pulses for a second range end gun.
