Abstract: A waterway for a boat amusement ride comprising first and second water troughs connected by a basin such that water flowing in the waterway changes direction through a sharp turning angle in flowing from the basin inlet to the basin outlet. Vanes in the basin cause a boat buoyantly supported and propelled by the water flow to move laterally such that the end of the boat first entering the basin leaves the basin behind the end of the boat last entering the basin, the orientation of the boat thereby being reversed as it passes through the basin. Optional elements for moving the boat laterally include water jets directed by nozzles on sidewalls of the basin and a rotating pushing member for engaging the last entering boat end. The pushing member may also be actuated laterally while abutting the last entering boat end.

Abstract: A vehicle system for high-speed passenger transport between metropolitan centers comprises a guideway having a pair of parallel guideway tubes; a plurality of carriages levitated and propelled by pressurized air stored within one or both tubes; and a passenger car connected to ride atop the carriages and tilt relative thereto. The passenger car and carriages cooperate to define lateral air cushion zones under the floor of the passenger car for supporting and tilting the passenger car by air pressure. The carriages have pluralities of lift cells partially surrounding each guideway tube, with active peripheral skirts for minimizing air leakage. Pressurized air stored within the guideway is used to supply the lift cells and cushion zones, and also to propel and brake the carriages. Ram air is collected during vehicle motion to help supply the lift cells and cushion zones.

Abstract: An improved runner for use with a SAILRAIL hydrostatic bearing levitation system is disclosed. The runner uses a substantially solid core having a degree of flexibility in a vertical plane, a thin pad of flexible, compliant material extending transversely around the core, and an outer flexible, compliant sheath enclosing the pad and the core. Flexibility is enhanced by a longitudinally extending slot cut into the core from the upper surface thereof. The side walls of the core are flat and straight and meet the lower convex surface of the core at a generally sharp longitudinal edge. Also the ends of the runner can angle upwardly to enhance the ability of the runner to traverse joints, gaps, or imperfections in the SAILRAIL rail. The runner can be secured to a deck member and provides specific advantages over prior art runners which had a larger profile, were more expensive and were not as efficient as the low profile runner of this invention.

Abstract: A Land transportation system has an unmanned mobile box which rides in a tube from one place to another. Guides are affixed to the center of the tube to cooperate with guide rollers on the box to stabilize the running of the box. Wings are provided on the side of the mobile box to provide a buoyancy effect while the box is running, thereby reducing the friction between the box and tube. Additional rollers are placed on the bottom of the box, and come into contact with the bottom surface of the tube when the box is running at slow speeds. The mobile box is driven by linear motor, with the controller for the motor being located outside the tube, and the primary and secondary coils of the motor being located in the tube and on the box. The mobile box also has a signal generator which transmits a prememorized identification signal to a receiver outside the box, to identify destination and other information about the mobile box as it traverses the tube.

Sheet material, such as ribbed plastic (nylon) sheeting, is automatically dispensed between the fingers and loading deck so that it provides a smooth surface as the finger traverses the dock. A frame is mounted to the front of the finger, with a shaft on which the sheet material is coiled mounted to the frame, and an air motor for applying a generally constant tension (e.g. about 10 lbs. per square inch) to the plastic sheet. A hook or magnet is mounted in a recess in the deck and engages the free, leading end of the sheet material to hold it stationary on the deck as the finger traverses the deck, and thereby provide for automatic dispensing and take up of the sheet material.

Abstract: A wafer transporter comprising a plurality of plane electrodes which are horizontally coplanar with each other. The plane electrodes face the wafer to be transported. A plurality of air nozzles are provided through the electrodes, and air is blown from the nozzles perpendicularly toward the wafer surface. A voltage is applied between the electrodes facing the wafer. The applied voltage is divided by the capacitances between the wafer which is electrically conductive, and the electrodes, thus the wafer is attracted vertically toward the electrode, and is maintained without friction by the balance of the repulsive force of the air blowing and the attractive electrostatic force. The divided voltages become unequal due to the difference of the wafer area facing respective electrodes. This voltage difference produces a horizontal force which moves the wafer in a horizontal direction. The wafer is forced to stay at a balancing point where the induced voltages are equal.

Abstract: Motion is imparted to a car (12) by a cable (10) that runs along the length of a guideway (14) in sheaves (22). To accommodate directional changes in the guideway (14), the sheaves (22) are oriented in a range of configurations, including orientations (22C, 22D) above the cable (10). A guiderail (30) is located high on a side of the guideway (14) and imparts guidance to the car (12) via a rail follower (38) on the car. A cable clamp (54) attaches the car (12) to the cable (10) and displaces the cable (10) a large amount from the sheaves (22) to avoid impingement of the clamp (54) and sheaves (22). The cable clamp (54) is disposed so as to occupy the area defined by the rail follower (38). Cable supports (56,56), disposed forward and rearward of the cable clamp (54) displace the cable (10) by a small amount from the sheaves (22) and replace the cable (10) onto the sheaves (22). The cable supports (56,56) are disposed so as to occupy the area defined by the cable as displaced (55) by the cable clamp (54).
