Abstract: Method and apparatus for analyzing current microclimate weather data and generating watering schedules according to present need. This method and apparatus further transmits these watering schedules to receivers within individual irrigation timers to adjust water application and saver water. Microclimate weather data is applied to each irrigation timer according to actual local watering need. Water supply flow and starting times are adjusted to distribute delivery loads on water pumping stations. Whereas each individual irrigation timer starts and stops independently in accord with the latest received schedules, immediate control is always available to the transmitting authority.

Abstract: To provide inexpensively a connector constructed of a steel pipe and bearing a tie function of a ladder-type sleeper for railway tracks, in a connector constructed of a steel pipe 1 used in the ladder-type sleeper for railway tracks integrated with longitudinal beams made of concrete and the connectors constructed of steel pipes 1 by feeding concrete, both end portions of the connector constructed of the steel pipe 1 are flattened in the horizontal direction and a corrosion resistant coating 4 is coated at portions of the connector constructed of the steel pipe 1 exposed to the atmosphere.

Abstract: A rail tie has a pair of rail supporting portions disposed on opposite sides of a central portion. The central portion is elevated relative to the central portion and supports a reaction rail of a linear induction motor used to propel a vehicle along the guideway. The reaction rail is secured to flanges extending laterally from the central portion to reduce the unsupported span of the reaction rail between ties. The tie is supported on the deck of the guideway by resilient pads. An eccentric insert cooperates with a securing stud to allow alignment of the tie.
