Abstract: A yard debris transportation device includes a multi-panel assembly that is moveable between a collection configuration and a transport configuration. The panel assembly includes first, second, third, and fourth panel sections that are hingeably connected in series. In the collection configuration, the panel sections are open and substantially flat, such as laying against the ground. After yard debris is placed thereon, the panel assembly is changed to the transport configuration, forming a shell about a cavity having the yard debris therein. The end panel sections overlap in the transport configuration so that cutouts on the end panel sections overlay one another, thereby forming at least one gripping hole. The gripping hole(s) are used as a handle to carry the panel assembly with the yard debris trapped therein from the collection location to the remote dumping location. The panel assembly is inserted into a trash bag and the gripping hole(s) is released.

Abstract: A regulating system for regulating a double-shaft gas turbine, wherein simultaneously: the fuel feed electrovalve is governed by a signal proportional to the difference between the number of revolutions per minute of the power turbine and a reference value; the movable nozzles of the power turbine are governed by a signal either proportional to the difference between the number of revolutions per minute of the compressor and a reference value, or proportional to the difference between the temperature of the exhaust gases and a relevant reference value; and the movable stator-blades of the compressor are governed by a signal proportional to the ratio between the revolutions per minute of the compressor to the square root of the ratio of the absolute ambient temperature to an absolute reference or design temperature.
