摘要： An irrigation emitter is provided for delivering irrigation water from a water supply conduit, such as an irrigation supply tube, pipe, or other water supply apparatus, at a low volume or drip-like flow rate. The emitter operates generally through the use of a reduced size orifice and a relatively long tortuous flow channel that cause a pressure reduction between the water supply conduit and an emitter outlet. The emitter includes an inlet for tapping a portion of the water flow from the water supply conduit and, when the water pressure is above a predetermined minimum level, directing the flow to and through the flow channel for subsequent discharge to a desired location. The emitter also may regulate to accommodate for changes in supply pressure. The emitter also may include multiple emitter outlets.

摘要： Methods and apparatus are provided herein for sensing rain fall for use in irrigation control. In one embodiment, a wireless rain sensor comprises a housing at least partially covering a first sensor, a controller and a wireless transmitter. The first sensor comprises a moisture absorptive material located to be contacted by rain fall and configured to expand in response to the contact with the rain fall and contract in response to an absence of the rain fall. The controller is coupled to the first sensor and configured to output signals corresponding to a variable amount of expansion and contraction of the moisture absorptive material. The wireless transmitter is configured to transmit wireless signals, at least one wireless signal comprising data corresponding to the variable amount of expansion and contraction of the moisture absorptive material.

摘要： A paint roller assembly for a pressurized paint supply system including a hollow roller arm, a delivery tube within the roller arm for receiving pressurized coating material such as paint therethrough, the tube terminating in a horizontally disposed end portion, a circular flange mechanically coupled to the roller arm inwardly of the end portion to prevent relative rotation therebetween, an annular sealing member received over the end portion and arranged to abut the circular flange while permitting relative rotational movement therebetween, a cylindrical roller core having one end received on the end portion, the core having an axially extending relatively shallow groove at its periphery along a major portion of its length, the roller core being recessed at the discharge end of the end portion to provide a sump therein of greater depth than the groove and communicating with the groove. Distributor means are positioned in the groove and have spaced apertures therealong to permit paint to flow from the groove into a perforated paint roller cover positioned over the roller core.
