Abstract: A device for removing unwanted vegetation consisting of a pole with a pair of cutting members on one end and two control handles on the other end. In use, the end with the cutting members is pulled through the vegetation and as the device moves, the offending vegetation is cut off by the cutting action produced by the pulling movement. If, during the cutting, the unwanted vegetation is found to be supple and yielding, a first handle is depressed. This brings the cutting members closer together and causes the supple vegetation to be sheared off. On the other hand, if, during the cutting, the unwanted vegetation pulls out of the ground and becomes lodged in the device, a second handle is depressed. This permits the cutting members to rotate away from each other thereby releasing the unwanted vegetation from the device.

Abstract: A fuel gas injector for a gas turbine engine employs a plurality of closely spaced parallel venturi tubes disposed in a pair of spaced-apart header plates. The venturi tubes are brazed to the header plates and the perimeters of the header plates are sealed to form a plenum into which pressurized gaseous fuel is supplied.
