Abstract: An arrangement is provided for improving the yield of potato crops. The arrangement includes a bed, a plurality of pairs of parallel rows of potato plants, and a drip irrigation tape. The bed is provided for multiple rows of potato plants. The plurality of pairs of parallel rows of potato plants in the bed have an inter-row gap between the rows in each pair of rows spaced from one another sufficiently to provide a moisture permeable agronomic soil corridor between the rows in each pair of rows to provide a supply of water to a root zone of each row within each pair of rows of potato plants while maintaining aerated soil within and above the agronomic soil corridor to reduce excessively wet conditions adjacent the crop canopy and a solar light corridor provided between adjacent pairs of rows to provide increased solar energy to the potato plants.

Abstract: A fluid delivery and control system is provided for a fluid delivery line having elastic components. The system includes a pressure sensor, an electronically controlled valve, processing circuitry, and computer program code logic. The pressure sensor is operative to detect fluid pressure within a fluid delivery line. The electronically controlled valve includes an adjustable flow regulating aperture disposed in the line, interposed along a linear flow axis, and operative to regulate fluid flow through the line. The processing circuitry communicates with the pressure sensor and the electronically controlled valve. The computer program code logic is executed by the processing circuitry and is configured to generate an output signal. The output signal comprises an operating parameter of at least one of the pressure sensor and the electronically controlled valve to adjust flow capacity of the flow regulating aperture of the valve to dissipate pressure oscillations within the fluid delivery line.

Abstract: Apparatus is disclosed having a circular wobble plate centrally mounted to a base plate via a spherical bearing. A roller assembly is attached about the center mounting point and radially projects intermediate the wobble plate and base plate to create a raised position of one portion of the wobble plate so that weight displacement atop the wobble plate will cause the wobble plate raised position to angularly rotate relative to the base plate.

Abstract: Apparatus is disclosed for removing snow from an inclined surface such as a structural roof, including an elongated flexible sheet having a low surface coefficient of friction, and adapted for sliding along the inclined surface, the sheet being attached to a rod and the rod having an attachment for propelling the apparatus.
