  • Patent number: 8924050
    Abstract: In a railway signalling system which transmits a control order to an on-board signalling system by a trackside signalling system, the on-board signalling system being mounted on a train running on a line and the control order being compliant with a signalling system of the line, the present invention allows the train to run through into lines with different signalling systems using a single on-board signalling system. When the train enters a line with a different signalling system from a current line, the on-board signalling system installs a train control application program compliant with the signalling system of the entering line. Then, the on-board signalling system executes the train control application program, allowing the train to be controlled on the entering line according to a control order created by the trackside signalling system of the entering line.

    Abstract: An autonomous robotic transport system has been developed in which the individual robot vehicles are able to move in multiple directions, such as vertically as well as around curves. Through the use of a unique rail system, the vehicle is able to move around corners and turns without the need for expensive modifications. This eliminates the need for various differentials or multiple electric motors to provide the difference between inner and outer wheels in a turn. Moreover, a number of switches have been developed that allow the vehicles to move not only vertically but also horizontally as well as transition between vertical and horizontal movement. A technique for operating the robotic vehicles is also described.

  • Patent number: 5007351
    Abstract: A mobile storage system includes mobile carriages that roll on rails embedded in a building floor. The carriages are driven along the rails by at least two flanged wheels that engage a grooved rail. The flanged wheels are preferably mounted in parallel channels located at the center of the carriages. The flanged wheels are driven in synchronization by a sprocket and chain drive. Either electric or manual power may be provided. In both cases, the sproket and chain drive is adjustable to provide proper chain tension to the wheels to improve tracking. Chain adjustment may be accomplished by an idler sprocket movably mounted to a carriage channel.

  • Patent number: 4876967
    Abstract: The transporter has a frame which is fastened to a side rail of a foremost one of a plurality of juxtapositioned plant trays. It has an electric motor mounted thereon, and a gear reducer coupled to the output or power end of the motor. The trays are supported on a pair of extended beams by rollers, underlying the trays, and fixed to the trays. The gear reducer drives a sprocket, and three rubber-tired wheels are rotatably supported by the frame and engage one of the beams; two of the wheels engage one side of the beam, and the other is equi-distant from the axes of the two and engaged with the beam on the opposite side. Each wheel has an axle journalled in the frame and having a sprocket fixed to an end thereof. A continuous chain is engaged with the driven sprocket, and with the other three; upon the motor being turned on, this causes the wheels to turn and travel along the engaged beam and, in this way, the whole plurality of trays are pushed along the two beams.

  • Patent number: 4811669
    Abstract: A portable drive for coaction with a band is provided with a motor driven drive roller for transporting the drive along the band. The drive roller with coacting structure for maintaining operative coaction with the band are settable to two main positions, viz, an operative and a neutral position, the band in the neutral position running freely while the drive roller with coacting structure being cantilevered so that the band can be freely taken aside for disengagement of the band from the drive, or for inserting the band from the side over the drive roller to coact therewith after resetting to the operative position. The inventive drive is primarily intended to be attachable to a skier allowing him to be towed up a hill along a band which is anchored at its upper end to a tree, for example.

  • Patent number: 4604020
    Abstract: A system for transfering discs, such as integrated circuit wafers during manufacture, from a location at atmospheric pressure into a vacuum chamber of an electron microscope or the like with a minimum of vacuum loss to the chamber. A wafer is placed on a moveable holder in a small sealable chamber having a sealable top door and which is mounted to the outer surface of the vacuum chamber at the position of a small gate through the chamber wall. The wafer holder carries a magnet that is magnetically coupled to a second magnet outside of the sealable chamber and which is motor driven to transfer the wafer through the gate and into the vacuum chamber and upon a stage that has a three-point grasping mechanism operated by the leading end of the moving wafer holder. The wafer holder includes a solenoid operated clip that engages the leading edge of a wafer during pick-up of the wafer for its removal from the vacuum chamber.

  • Patent number: 4576099
    Abstract: A pallet transport apparatus includes individual pallets which travel in succession on a run way, each of the pallets containing an in-line indexing dual-cam mechanism and a drive motor for the cam mechanism for controlled rotation, and the run way including pairs of cam followers which are arranged at regular intervals along the run way and each of which engages the corresponding cam plates on a pallet facing it. The pallets can travel and remain motionless every one pitch as determined by the interval between the adjacent cam follower pairs.

  • Patent number: 4538522
    Abstract: An improved cable following apparatus especially suitable for use in replacing an existing underground cable is disclosed herein. This apparatus utilizes a telescopically configured main body disposed around a cable in question and front and rear cable gripping mechanisms which alternatively grip the cable so as to cause the telescopic body to slide along the latter in a forward direction. The cable following apparatus also includes a technique for releasing both of the gripping mechanisms from the cable at the same time in order to be able to pull the entire apparatus rearwardly in the event it becomes necessary or desirable to do so.

  • Patent number: 4467924
    Abstract: A movable aisle storage system is provided having rail and panel connector units which perform the dual functions of forming the rails and interconnecting the deck panels of the system track and deck assembly. Each connector unit has a substantially cylindrical rail portion and a depending support portion having a pair of upwardly and outwardly extending flange sections which support and secure the sides of the deck panels. Levelling screws threadedly engaging the unit support portion are seated in a channel to facilitate system installation and prevent floor damage. Flexible seal strips are used between the rails and panels thereby reducing system maintenance and permitting access to the levelling screws after system installation. Rail sections are joined to form an extended track by a self-tightening rail section joiner having a pair of tapered head machine screws which threadedly engage holes in abutting rail sections. A joiner member overlies the rail section holes and has openings to receive the screws.

  • Patent number: 4334816
    Abstract: An automated assembly, maintenance, and repair system for the construction of a large space structure. The space structure comprises a plurality of trusses and truss junctions that in turn are made up of a plurality of individual struts and nodes. The truss assemblies are progressively built by an assembler trolley as the trolley crawls along the constructed truss. The trolley comprises a forward crawler and a rear crawler joined by an articulated coupler. The crawlers are carried along the structure by belt transports incorporating grippers that engage the truss structure at the nodes. Manipulator arms for strut and node assembly are located on the forward crawler, and the majority of control, power, and communication systems are located in the rear crawler. Cargo canisters filled with component parts for constructing the space structure are carried by the forward crawler. The space structure configuration is determined by the arrangement of the individual struts and nodes during the assembly process.
