Abstract: An irrigation device comprising a moisture responsive barrier is provided. At least a portion of the barrier has perforations, at least some of the perforations are associated with a water swellable material. The perforations are configured to open as the water swellable material loses moisture and dries out and are configured to close as said water swellable material is exposed to and absorbs water, such as during a watering step. According to another aspect the irrigation method includes the steps of positioning a perforated barrier between a source of irrigation water and an area to be irrigated, wherein the perforations are associated with a water swellable material; exposing the water swellable material to water to cause the water swellable material to swell to close the perforations; and permitting the water swellable material to dry, to open the perforations, whereby the opening and closing of the perforations regulates the amount of irrigation water being applied across the barrier in the irrigation method.

Abstract translation: 提供了包括湿气响应屏障的灌溉装置。 屏障的至少一部分具有穿孔，至少一些穿孔与水可溶胀材料相关联。 穿孔被配置成当水溶胀材料失去水分并干燥时打开，并且如所述水可溶胀材料暴露并吸收水（例如在浇水步骤期间）被构造成关闭。 根据另一方面，所述灌溉方法包括以下步骤：在冲洗水源和待灌溉区域之间设置穿孔障碍物，其中所述穿孔与水可溶胀材料相关联; 将水可膨胀材料暴露于水中，使水膨胀材料膨胀以封闭穿孔; 并且允许水可溶胀材料干燥以打开穿孔，由此穿孔的打开和关闭调节在冲洗方法中跨越屏障施加的冲洗水的量。

Abstract: A roof vent for an off peak roof location. The roof vent has a base and vent cap. The base includes an attachment flange, a central opening and an upstanding wall surrounding the central opening. The vent cap covers the central opening and has a solid periphery extending down to the attachment flange, and a grill portion located on an outer upwardly facing surface of the cap. A barrier platform is disposed under the grill portion over the central opening to deflect moisture passing through the grill away from the central opening. Vented air passes through the central opening, between the underside of the barrier platform and the attachment flange, between the top side of the barrier platform and the underside of the vent cap and then out through the grill.
