    摘要： A utility vehicle or other device for excavating soil or the like includes a utility mechanism, such as, e.g., a trencher, an auger or the like, with a motor-driven utility drum. In preferred embodiments, the motor is contained substantially entirely inside the drum. Preferably, the drive shaft is operatively connected to the drum to rotate the drum at a connection location that is displaced inward from ends of the drum. In some embodiments, the drive shaft is also preferably operatively connected to a second utility mechanism, such as, e.g., a trencher chain. In some embodiments, a planetary transmission is also located inside the drum.

    摘要： A boom and linkage mechanism for a skid-steer loader includes a frame and a right and a left loader arms. An implement may be vertically pivotally mounted to the forward ends of the loader arms, and a pair of tilt actuators may be respectively connected between the forward ends and the implement. Right and left forward guide links are connected between the frame and the loader arms. Right and left rearward guide links are connected substantially proximate to a rear of the frame and the loader arms. The lower ends of the rear guide links may be substantially lower than the lower ends of the forward guide links. Right and left lift actuators may be connected between the frame and the loader arms. The right and left lift actuators may extend and retract to raise the right and left loader arms such that the implement moves between a fully lowered position and a fully raised position, and wherein the fully raised position is located substantially vertically above the fully lowered position.

    摘要： A blur film is made of a polymeric film material transmissive to infrared energy of a selected waveband, which is affixed to a surface of a substrate transmissive to energy of the same selected infrared waveband. The blur film has a texture or a plurality of lenslets thereon, where the surface of each lenslet is a surface of revolution. In a spatial-filter wheel application, the blur film and substrate are affixed to a support, which in turn is rotatably mounted on a drive. The support is structured such that a portion of its circumference is covered by the blur film and a portion of its circumference is not covered by the blur film. The spatial-filter wheel is rotated in front of a detector to produce alternating blurred and direct images on the detector.

    摘要： A plurality of water- and oil-porous sacks are partially filled with a number of generally toroidal bodies of a polymer material that entraps oil and including mesh fragments scattered throughout the bodies. Each sack is sewn with a perimeter stiffening ring, to retain a flat profile, and has a netting that closes to help inhibit outflow of the oil when the sack is retrieved. When deployed from ship or by air onto a spill, the sacks spread into a pancake shape and the polymer matter forms a single layer that retains the oil. The inventive sacks will float indefinitely without releasing the oil or allowing it to emulsify, so the oil can remain in place until collection efforts are feasible. The sacks can be burned in situ, or standard fishing boats or specialized collection boats can be used to retrieve the sacks, and the collected material can be burned to capture the energy content of the oil or processed to separate the oil from the polymer. The inventive sacks can be used in conjunction with other, known containment or retrieval equipment, such as booms or skimmers. The system is specifically designed for rapid deployment and efficiency in rough water.
