Abstract: A plant extracting assembly includes a fulcrum; a lifting arm subassembly carried by the fulcrum in fixed relation thereto, the lifting arm subassembly having a lifting arm jaw; a kinetic arm subassembly having a kinetic arm jaw disposed in facing relation to the lifting arm jaw of the lifting arm subassembly; and a pivoting lever carried by the lifting arm subassembly and pivotally engaging the kinetic arm subassembly, the lever operable to selectively displace the kinetic arm jaw toward and away from the lifting arm jaw by pivotal actuation of the kinetic arm subassembly responsive to pivoting of the lever relative to the fulcrum.

Abstract: A process for the in-situ formation of a lubricating phase comprising sulphur and tin in a friction material, wherein reaction of a sulphur source with a tin source in said friction material results in the formation of said lubricating phase, and wherein said reaction is initiated or effected by heat resulting, in use, from the generation of friction, wherein said sulphur source is selected from one or both of sulphur and/or a metal sulphide selected from one or more of iron, copper, zinc, titanium and bismuth, and wherein said tin source is selected from one or more of tin, a tin-containing compound and/or a tin-containing alloy.

Abstract: A decorative A-frame type water transfer bridge is provided for selectively siphoning water from one or more aquarium fish tanks. A siphon pump evacuates the desired amount of air to cause the water to enter and fill the bridge. A bleeder valve with a visually perceptible air lock permits the user to control the exact amount of air to be evacuated without spillage of water or retention of unwanted air bubbles.
