摘要:
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. The method still further includes closing the collecting apparatus, storing it in a container, closing the container, transporting the container to a product recovery site, cleaning the closed collecting apparatuses at the product recovery site, opening the clean collecting apparatuses, and recovering the secretions from the clean collecting apparatuses.
摘要:
An apparatus and method for fluid emission control of a conductive fluid utilizes a passive electrolytic reaction to ionize the conductive fluid. The apparatus includes a fluid emission system having a reaction chamber that includes an anode and cathode to initiate an electrolytic reaction within the conductive fluid and reaction chamber. An ion-generating member is disposed within the reaction chamber and enhances the electrical bias in the conductive fluid. An oxidation-controlling member disposed within the reaction chamber retards oxidation of the anode and cathode. The metallic component parts and amount of such component parts used in the reaction chamber are chosen to achieve a target voltage, which that amount of voltage created, by the electrolytic reaction necessary to charge a fluid droplet of any density to achieve a maximum acceleration of fluid droplets as the fluid droplets enter and leave a spray cone.
摘要:
A method of improving the spraying of liquid droplets from a spray device onto a surface which method comprises imparting a unipolar charge to the said liquid droplets by double layer charging during the spraying of the liquid droplets from the spray device, the unipolar charge being at a level such that the said droplets have a charge to mass ratio of at least ±1×10−4 C/kg, whereby the charged droplets of the liquid are mutually repelled thereby increasing the spread of the droplets from a central spray line extending from the head of the spray device and avoiding coalescence of the droplets, thus providing a more even coverage of the surface which is to be sprayed. In particular, the method enables liquid droplets to be sprayed onto a surface which is obscured by all object located between the surface and the spray device.

摘要:
A device for protecting the connection of a tubular conduit to a main tube of a maple sap collecting system wherein sap collected from maple trees are directed under vacuum to a pumping station of a sap processing center. The device comprises a band having a first end adapted to be mounted to the main tube and an opposite end adapted to be mounted externally onto the tubular conduit at a given distance from the main tube. This distance is greater than the distance between the first and opposite ends of the band so that accidental impact on the tubular conduit resulting from falling objects and tension applied to the attachment of the conduit to the main tube are taken by the band to thereby protect the connection of the tubular conduit to the adapter.

The invention provides an aerosol delivery method and system for producing a charged electrohydrodynamic (EHD) aerosol, discharging the aerosol and moving the discharged aerosol in a desired direction without substantial wetting of the device. The delivery system may include a spray nozzle for dispensing the fluid to be aerosolized and negatively charging the aerosol droplets, a discharge electrode generally downstream of the spray nozzle for generating a positive ion stream which intercepts and electrically neutralizes the negative aerosol droplets while also imparting a desired movement on the aerosol in a direction generally away from the discharge electrode and a reference electrode between the spray nozzle and the discharge electrode for modifying the electric field between the spray nozzle and the discharge electrode.
