    摘要： An off road vehicle of the kind having fluid-distensible bag rollers for supporting the vehicle load uses bag rollers which are constructed to afford maximum flexibility in both the walls and tread and which are also constructed to be dynamically balanced. The vehicle also incorporates suspensions which effectively dampen oscillation of the bag rollers to facilitate and to permit high speed operations of the vehicle across rough terrain. A top drive roller is associated with a bag roller in certain embodiments of the off road vehicle in ways which minimize bag wear. Specific bag constructions are provided for improved operation of the off road vehicle for on-highway use. The vehicle includes two frame sections which are connected to permit frame (yaw) steering and swiveling (roll) between the two sections while preventing a bending between the frame sections (pitch) to thereby provide a strong back mode of operation. When equipped with 4 bags on each frame, the vehicle permits increased speed over rough terrain. The bag roller in a fixed position serves as a transport device for supporting and moving material having uneven and/or fragile surfaces and, in a specific embodiment, is mounted in a support for use as a transportation element in a conveyer system, or as a forceful puller for lineal objects, such as pipelines, accommodating uneven dimensions.

    摘要： An arctic vehicle is provided for the rapid transport of goods, machinery, and personnel over ice, snow and frozen ground surfaces.The vehicle is supported partially while at rest and/or under way by a cushion of air which is entrained by a system of seals. Seals along the sides terminate in runners for guiding and partially supporting the vehicles. A cutter system is deployed in front of each runner to form smooth running tracks or furrows over ice, snow, and frozen ground surfaces. A transverse cutter may be deployed in front of the forward transverse seal for removing major ice protrusions between the runners, to reduce seal leakage and wear, and improve ride characteristics. The cut tracks, in addition to providing smooth transit, engage the runners and side seals to prevent lateral shifting of the vehicle by the action of crosswinds and sideslopes.The vehicle may be self-propelled or towed. Through the use of the air cushion, frictional resistance to movement is substantially reduced, requiring correspondingly less motive power or towing force. Also the load of the vehicle is distributed over a larger area.The vehicle may be part of a train system pulling similar cars whose running friction is reduced by a common air bubble formed between longitudinal seals of the driving vehicle and drawn cars and end seals. In the alternative, the driving vehicle and each drawn car may be provided with an air pressure seal system to provide individually contained air bubbles.

    摘要： A cleated roller enclosing an internal combustion engine is provided with two handles containing means for engaging the posterior of a skier. The engine is mounted within the roller on a frame which in turn is mounted to both of the roller hubs which are hollow. The roller hubs are connected to the handles. The engine's output shaft is operatively connected to both end walls of the roller so as to rotate the roller relative to the roller hubs. The roller hubs are in direct fluid communication with the atmosphere outside the roller so as to permit efficient cooling of the engine by a forced airflow through the hubs and the roller.
