Abstract: A process for harvesting organic material recovers sugars, proteins, aromatics, organic acids and mixtures thereof, from the sapwood of trees or recently pruned sections, e.g. branches. The process involves drilling entry and exit ports to access the sapwood layer and the use of spiles, driven into the ports, to create fluid tight seals for the tubing, which delivers and recovers the solution, which solubilizes the harvested organic material and flows through the sapwood layer. The close proximity of entry and exit ports permits the flow of a pressurized solution. The recovered pumped solution or products therefrom, if desired, can be used in a fermentation medium to prepare products, e.g. alcohol, fatty acids.

Abstract: A method for stimulating resin formation in all breeds of Aquilaria tree. The method including selecting an Aquilaria tree that is at least five years old, having a trunk diameter between 4 inches and 6 meters. The method also includes wounding the tree by removing section of an outer layer of the trunk and forming holes in the wounding. Finally, the resin which results from the holes in the wound is harvested.

Abstract: An air driven liquid pump includes a reservoir, a liquid inlet aperture extending through the reservoir wall for fluid coupling to a liquid inlet duct, a liquid outlet aperture extending through the reservoir wall for fluid coupling to a liquid outlet duct. The liquid outlet aperture is in fluid communication with an outlet level inside the reservoir chamber located below the liquid inlet aperture and corresponding to a predetermined lower threshold value of the volume of the liquid within the reservoir chamber. The liquid pump also includes an air aperture extending through the reservoir wall for pneumatically coupling the reservoir chamber with the atmospheric air located exteriorly to the reservoir, a liquid inlet valve operationally coupled to the liquid inlet aperture and an air valve operatively coupled to the air aperture.

Abstract: A method and compositions for increasing ectomycorrhizal colonization of the roots of trees using an alkali metal formononetinate, formononetin or mixtures thereof is described. The method enhances the growth of healthy and impaired trees.

Abstract: The invention relates to a chassis structure for a working machine moving on a terrain, the chassis structure (40, 60) comprising a pair of front wheels and a pair of rear wheels supporting the frame (41 to 42, 61 to 62), and a controlled frame joint (63) between the frame parts (41, 42, 61, 62), when the frame is composed of two frame parts. The chassis structure (40, 60) further comprises a suspension (1a) controlled by actuators and arranged to move each wheel in a level transverse in relation to the frame. Each wheel is mounted rotatably and to turn by means of the actuators to the suspension, and each wheel is usually provided with hub motor means for drive transmission. The chassis structure (40, 60) can further comprise a pair of middle wheels for a second frame part (42, 62). In a method related to the chassis structure (40, 60) the forest machine can also be turned in place.

Abstract: The Planter Security Barricade System or PSBS is a lightweight decorative planter with pre-engineered interior barrier form and steel rebar caging. The planter and interior barrier are made of glass fiber reinforced concrete, a proprietary compound of graded stone and cement reinforced with long-strand alkaline resistant glass fibers. The result is a composite that combines the strength and lightweight characteristics of conventional fiberglass with the durability and longevity of cast stone. Specifically, the planter barricade consist of: 1) an outer planter shell made of composite cement and graded stone embedded with strands of glass fibers; 2) a pre-engineered barrier form that has an upwardly extending narrow wall portion and a wide base lower portion; and 3) a standard rebar caging design consisting of a plurality of L-shaped standard grade steel rebar assembled to a cross-member from the top and middle portions.

Abstract: A method of collecting secretions from trees including making a predetermined shaped incision through the bark to the surface of the wood and applying a secretion flow activation agent to the incision. The method further includes placing a receptacle in the incision, wherein the receptacle comprises a lower outer part and a flow tube portion located at the lower outer part, and wherein a portion of the receptacle has the same shape as the predetermined shape of the incision. The method further includes fixing a collecting apparatus to the flow tube and subsequently removing the collecting apparatus from the flow tube when the collecting apparatus contains secretions from the trees.

Abstract: Described is a method of chemically increasing the amount of extractable cedarwood oil from Juniperus Mexicana (commonly known as "Texas cedarwood") by treating standing living Juniperus Mexicana with a solution comprising a bipyridylium salt and permitting said trees to continue to grow in their natural environment for a period of time of at least two months. Portions of the trees are then cut and the cedarwood oil is extracted therefrom using unit operations including, but not limited to, steam distillation, in relatively large yields.

Abstract: Disclosed is an improved method of inducing lightwood formation in a living conifer. The improved method comprises heating the sapwood of a selected section of a conifer to a temperature of from about 40.degree. C. to about 100.degree. C. by means of an energy source such as radiant energy.

Abstract: An apparatus for shielding the tapping cuts of rubber trees from rainwater is disclosed, which comprises an aluminum foil strip sufficiently malleable to conform to the pattern of the bark of the tree to which it is affixed. The foil strip is preferably pleated, folded or wrinkled so as to provide for sufficient elongation to accommodate both the perimeter of the bark and expansion in the girth of the tree. A method for preparing the foil strip and adhering it to the tree is also disclosed.

Abstract: Stimulation of oleoresin production associated with living cells can be chemically induced with dilute systemic application of ethylene or ethylene-releasing compounds. One such ethylene-releasing compound is 2-chloroethylphosphonic acid. A further increase in oleoresin production can be accomplished by using ethylene-releasing chemicals in combination with the bipyridilium salts, diquat or paraquat. Through the application of ethylene-releasing chemicals in combination with a bipyridilium salt, the effect of lightwood inducing chemicals is expanded over a larger portion of the treated tree, and more oleoresin is produced. Oleoresins are extracted from the trees by known methods, and the naval stores products are recovered therefrom.

Abstract: Apparatus and method for drilling a borehole into the sapwood of a tree and injecting a chemical solution into the borehole, preferably during withdrawal of the drill bit, including facilities for supplying a liquid through a passageway within the bit and facilities for injecting a quantity of liquid, proportional to the volume of the borehole and allocated simultaneously with and in response to progression of the drill bit, into the borehole as the drill bit is being withdrawn therefrom.

Abstract: In a process for chemically stimulating the production of oleoresinous material in association with living wood cells it is advantageous to use a dilute dispersion of primary amine.

Abstract: Disclosed is a method of preparing a treatment site on the bole of a conifer.
