  • Patent number: 7406919
    Abstract: A method and apparatus for operating a vehicle to be driven on the road as well as railroad tracks includes an auxiliary drive suspended below a frame of the vehicle. The auxiliary drive includes a hydraulic roller assembly having a roller component for engaging a tire of a vehicle to be propelled. A hydraulic cylinder extends said roller component from a first, unengaged position to a second, engaged position. A hydraulic motor is operatively connected to a chain drive for driving said roller component so that said roller component rotates and imparts a corresponding rotary force to the tire of the vehicle. In operation, the vehicle is placed in neutral and the auxiliary drive is actuated. The auxiliary drive can be controlled at any location, thereby allowing the vehicle to be driven without a driver.

  • Patent number: 5623878
    Abstract: A dynamic ride vehicle for executing a sequence of distinct motion patterns and for providing unique ride experiences in an amusement park attraction or other environment includes a movable chassis and a body having a passenger seating area. A motion apparatus, including computer controlled actuators, imparts motion to the body along a plurality of axes independent of any motion of the chassis as it moves along a path. As the vehicle travels along the path, articulation of the body and appropriate steering of the vehicle enables the vehicle to execute, in cooperation with the motion apparatus, a sequence of distinct motion patterns. Execution of the motion patterns enhances the passengers' sensation of vehicle movement that is actually taking place, as well as the sensation of a realistic moving ride vehicle experience that is actually not happening.

  • Patent number: 5473990
    Abstract: This disclosure provides to a ride vehicle for used in an amusement attraction. The ride vehicle mounts a structure upon a hydraulically-actuated motion base, so that the passenger holding structure may be articulated about one or more axes as the vehicle moves. Thus, this "simulator ride" carries passengers through three-dimensional scenery and articulates the passenger holding structure in synchronism with motions of the ride vehicle, the motions of moving show sets, which are external to the vehicle, sound, projection and other effects. The ride vehicle is programmably-controlled, and derives electrical power from a track mounted power bus to drive vehicle hydraulics, which drive motion base actuation, steering and vehicle velocity.

  • Patent number: 5441434
    Abstract: A magnetic conveyance system uses magnetic drivers within a tube having pressurized fluid moving therethrough. The magnetic drivers have magnets mounted at an angle other than 90 degrees to the central axis of the tube. Outside of the tube, a cart has a magnet thereon and is moved by magnetic force interaction when the driver is moved by pressure of the fluid, preferably a liquid such as water. A number of balls flow in the tube and keep the magnetic drivers spaced apart. The balls also serve to push the magnetic drivers as the balls are more directly pushed by the pressure of the fluid. A water wheel is connected by gears to an index wheel and serves to keep the balls, and thus the magnetic drivers and associated carts, moving in the proper direction. The carts may be configured as model cars, trucks, and other such vehicles which move on a board having a simulated road surface with the pressurized fluid tube mounted thereunder.

  • Patent number: 4590420
    Abstract: The invention proposes apparatus for testing plastic profiles or sections, particularly extruded polyethylene tubes which have been cross-linked by radiation, although the application of the invention is not restricted to that field. An electrode at a high potential and a grounded electrode are provided and surround the moving plastic section. A probe consisting preferably of a metal braid is disposed inside the profile or section adjacent to the apparatus and is preferably magnetically held and is not directly conductively grounded to the outside. Defects such as electron punctures in the wall of the plastic profile or section are detected by the breakdowns which are effected at the locations of said defects. It will be understood that the apparatus proposed by the invention can also be used to detect the location of other defects, such as contraction holes, inclusions, bubbles etc., and to deliver control signals to suitable devices for marking, rejecting etc.

  • Patent number: 4512260
    Abstract: The piston rod of at least one hydraulic cylinder is axially connected to a pivot pin about which the car holding arm of a car holding device rotates in a vertical plane to engage the couplings between railroad cars. In the case of a single hydraulic cylinder, the inner chamber of the cylinder, located closest to the car holding arm, is connected to the outer chamber on the other side of the piston by a conduit. When hydraulic cylinders are connected to each pivot pin of the car holding arm, the inner chambers of the two cylinders are interconnected by a conduit as are the two outer chambers. When flow through the conduits is blocked by a solenoid valve, movement of the car holding arm in the direction parallel to the track is resisted and the arm holds the train in position.
