Abstract: A method of inserting a tree tap into a tree, the tree tap including a blade in which a passageway is defined. The method includes abutting a distal end of the blade against an outer surface of the tree, followed by impacting the tree tap to drive the blade in to the tree. Afterwards, a cavity is drilled in the tree adjacent the blade distal end through the passageway. Also, a tree tap usable to perform the method.

Abstract: The invention relates to a method for collecting sap from a tree. The method comprises a collection stage and an analysis stage, in which the purity of the sap being collected is determined and, on the basis of the information obtained, the collection stage is terminated. With the aid of the method, sap is produced, in which additives are not used, and which is not heat-treated, and which has, however, good preservability at room temperature. The invention also relates to an apparatus for collecting sap from a tree.

Abstract: A sap collection assembly to collect sap from sap producing trees includes a cover superposed about a sapling or branch cut surface with one or more spacers used to maintain a gap between the cover and the cut surface. Elastomeric bands with an optional hose clamp are used to secure the cover to the sapling or branch to create an airtight seal between the cover and the cut surface. A bore hole is created in the sapling or tree branch has one end substantially central to the cut surface and a second end exiting a sidewall of the sapling or branch. Taps with optional tabs are secured to the sapling or branch to retrieve sap from the cut surface and bore. For angled bore holes, a modified tap includes a sapling nozzle angled relative to the tap body to accommodate an angled bore.

Abstract: The device is provided for collecting sap from a tapped hole of a tree. It includes a collector having a substantially frustoconical outer peripheral wall surface and an inner peripheral wall surface. The collector also has a portion that is removably insertable into the tapped hole with a frictional engagement. The material between the peripheral wall surfaces at the removably-insertable collector portion is elastically and temporality deformable in response to a peripheral pressure exerted inwardly on the outer peripheral wall surface when the removably-insertable collector portion is inserted with a forced frictional fit into the tapped hole.

Abstract: Pervaporation device for the desalination of salt water comprising a channel or cavity for holding or transporting salt water and a liquid-water-impermeable, water-vapour-permeable non-porous membrane, which is made of a copolyether amide wherein the polyether and (poly)amide segments are linked via amide bridges.
