  • Patent number: 7069612
    Abstract: One end of a passenger bridge or a goods-handling device of mobile type can be expediently and securely connected to a door on a craft, especially an aircraft, by determining the position of the door in relation to a reference point on the craft and storing it in a computer system. Furthermore, the absolute position of the door when the craft has come to a halt and the passenger bridge or the goods-handling device is to be connected, is determined by measuring the distance from a reference point on the ground to the craft. Finally, the computer system guides the passenger bridge to the door of the craft, the position of the end of the passenger bridge or the goods-handling device being determined during the guiding operation and inputted into the computer system.

  • Patent number: 6988851
    Abstract: A vibratory concrete screed includes a vibration isolation system that minimizes the transmission of vibrations to the operator under normal operating conditions, but becomes more rigid during screed control forces applied to the blade through the isolation system when the operator applies greater forces to the operator handle. The system includes low durometer elastomer vibration isolators isolating the operator handle from the vibration exciter and screed blade in a manner that limits vertical compressive movement of the isolators, yet permits substantially greater horizontal shear movement to effectively isolate the operator from vibration. The isolator mounting arrangement also includes retainers that engage the isolator to limit the amplitude of horizontal shear movement when the operator applies a greater control force to the operator handle.

  • Patent number: 6942041
    Abstract: A self-propelled agricultural vehicle is constructed by assembling the parts of a standard row-crop tractor to the point where the next step is that of mounting the cab to the chassis. At this point, a cab adapter module is mounted to the chassis using the mounting points normally used for mounting the cab to the chassis. The cab, provided in a form without the usual access ladder and fenders, is mounted to the cab adapter module so as to face in a direction opposite to that which it would face if mounted to the chassis. The seat and all controls for operating the tractor remain in the same locations in the cab regardless which direction the cab faces. Minor reconfigurations of hydraulic circuitry and the differential are required for permitting the vehicle to be operated in a forward direction opposite to that for the operation of the standard tractor.

  • Patent number: 6935435
    Abstract: A cultivating implement has transversely opposing sub-frames slidably mounted in the main frame of the implement to permit lateral positional adjustment of work implements carried by the sub-frames. The work implements are supported by a mounting apparatus providing a tilt adjustment, a horizontal rotational adjustment, and a transverse spacing adjustment for each respective work implement. A tilt control plate limits the transverse tilting movement of the work implement, while a rotation control plate limits the rotational movement of the work implement in a horizontal plane. A rotatable powered brush attachment can be supported on the sub-frame to provide a gentle cultivating action for the edges of plastic material covering the crop row. A pivot linkage operated through a hydraulic actuator provides simultaneous lateral movement of the opposing sub-frames to affect selective positional adjustment of the work implements. The frame is pivoted to the hitch to offset side hill operation.
