Abstract: A component many of which to be joined together to form a rodent barrier consists of a protruding rod and two protruding rods and two holes for linking the component with other components which have the same or similar dimensions and constructions of the component to be joined; the protruding rod is generally perpendicular to the two protruding rods and the two holes for linking the component with other components; two variations of the components presented.

Abstract: A rat/squirrel barrier which consists of a row of rods which extrude from a strip that is bendable to form a loop to be mounted on a tree branch so that the row of rods fan outwards from the loop to form a barrier; the strip having many generally “V” or “U”-shaped notches to facilitate the bendability of the strip; the strip having a step-up section beyond the row of rods; the strip and its step-up section having many studs and/or holes which when being put together can engage each other to enable the joining of two or more of the strips or the loop; the strip optionally having a longitudinal depressed area.

Abstract: A water vapor collector assembly, which consists of an optional capillary net, a dome, a water conveying channel, an optional capillary mat, a floatation base, and a water tube anchor, which many of it can be looped together by ropes and tubes and can float on sea surface to take sun rays to generate freshwater.

Abstract: A water vapor collector assembly consists of a transparent cover and a box which will float on a water surface. The transparent cover allows sun rays to evaporate some water in the box which confines and collect the vapor condensates. The condensates will be conveyed away by a tube under the box. A water wave operated shaker, a wind operated knocker, inserts to increase the water condensation surfaces, and various kinds of the box are also introduced.

Abstract: A water vapor collector bottle consists of a transparent cover, a top box, a water supplier, an optional insulator, an optional bottom cover, and a bottom box. The transparent cover allows sun rays to evaporate some water to the top box which confines and collect the vapor condensate. The condensates will drop into a container in the bottom box. A wind operated knocker and an insert to increase the water condensation surfaces are also introduced.

Abstract: For combination with a faucet having an upper surface, and a downward water outlet below the upper surface, the combination comprising a cup shaped flexible gasket that opens upwardly, the gasket having an annular wall adapted to interfit the faucet outlet, the gasket having a lower portion defining a discharge outlet and which is downwardly urged in response to water pressure entrains into the gasket via the faucet outlet, and means for releasably holding the gasket upwardly in annularly interfitting relation with the faucet outlet whereby the gasket annular wall seals against the faucet in response to the downwardly urging of the gasket.

Abstract: A jet flow propelled surfboard assembly comprises a longitudinally forwardly elongated structure including a flotation board to support a surfer and two positive displacement pumps which pistons can be manually operated in seesaw-like actions by feet of the surfer to generate jet flows to propel the surfboard assembly.
