Abstract: This invention relates to methods and compositions for combating mountain pine beetle (Dendroctonus ponderosae) which causes severe damage to pine trees in North America. A method and apparatus for reducing attack by mountain pine beetles Dendroctonus ponderosae on pine trees, Pinus species, by spacially deploying verbenone (4,6,6-trimethylbicyclo[3.1.1]hept-3-en-2-one) in stands of pine trees.

Abstract: A device (1) for ejection of boxes (30) through an exit (3) of a container (2). Such a device (1) may be used for the ejection of chaff for the purpose of radar jamming. The device (1) is provided with gear wheels (13, 13') located adjacent to the exit (3). In order to eject chaff boxes (30) the gear wheels (13, 13') engage with peripherally located gear means (37, 38) on the boxes (30). Ejection by means of such a gear arrangement enables the number of boxes (30) released and the time interval between subsequent releases to be controlled very accurately.

Abstract: The invention relates to a container for jamming means (4), for example, radar chaff, IR burning bodies or similar. Such containers (1) filled with jamming means (4) are arranged behind each other in a storing space in connection to dispensing device on an aircraft, for example, an aeroplane. For the purpose of diverting or for other purpose the containers are dispensed from the dispenser device. The container according to the invention comprises a frame construction (2) and a loosly installed insert (3) in this frame construction defining a space for the jamming means (4). The assembled container has a low weight in combination with good rigidity when the insert is installed in the frame construction, but in a separated condition as the frame construction and the insert are easily deformable.

Abstract: A releasing device for disconnecting a buoyant body from an anchor a predetermined period after having been sunk into water.In order to accomplish a reliable device, which may be stored for very long periods of time, a piston is movable in a cylinder under the influence of a spring and a water pressure differential. The piston controls the disconnection of the buoyant body and the anchor, as the cylinder is connected to one part and the piston will release an element connected to the other part in a disconnecting position under the influence of the spring.
