  • Patent number: 4108078
    Abstract: In a coupling apparatus for a circulating tow conveyor in which the carriages are held on a track with a portion running parallel to circulating tow chain and in which a coupling finger on the tow chain cooperates with coupling means on the conveyor, the coupling finger of the tow chain is pivotally mounted in a housing and is normally held in its vertical position by means of a locking lever which prevents the finger from pivoting out of contact with the cooperating coupling on the carriage but does not prevent pivotal movement of the finger in the opposite direction so that carriages pushed faster than the tow chain moves can be moved past one or more fingers on the tow chain. A releasing lever is provided to release the locking lever and, therefore, the carriage when the release lever is operated.

  • Patent number: 4102272
    Abstract: A high-speed transportation system employing a pivotally supported guide rail structure made of sections connected by expansion joints, with a self-propelled airplane automatically steered to fly along the guide rail with minimum force therebetween by a control system that is inclusive of displacement sensors associated with air bearings coupling the aircraft to the guide rail. A wheeled construction having wheels that can be driven, braked or free wheeling is provided that is automatically lowered or maintained in a lowered position contacting the guide rail whenever the aircraft lacks flying speed or the wheels are either driven or braked. The air bearings urge centering of the rail both vertically and laterally with respect thereto. Flight stability of the aircraft is enhanced by the provision of a ground effect bed, and gust spoilers, with the latter additionally functioning as a noise abatement device.

  • Patent number: 4096806
    Abstract: In a track tamping machine, opposed pivotally mounted tamping arms are oscillated by respective single acting hydraulic cylinders controlled by one or more hydraulic duplex rotary distributing valves. Fluid supply and return lines for each piston assembly are connected to a source of pressurized hydraulic fluid by way of a respective rotary valve. Each valve has a stationary ported shell which receives a rotary cylindrical spool having a pair of axially displaced supply and return throughports which alternately register with supply and return line ports in the shell to open and close the connections between the oscillating cylinder and the supply and return lines. Such oscillating cylinders are useful in controlling the vibration of the tamper arms in a track tamper unit.
