  • Patent number: 5590605
    Abstract: A transport system for moving along a track on a support surface. The system includes a body, a guide system and a powered self-steering caster assembly. The guide system cooperates with the track to apply lateral forces to the body to guide it along a predetermined path when a propulsive force is applied to the body. The powered self-steering caster assembly has a pivot joint and a wheel driven by a motor. The wheel has a center of rotation and is rotatably mounted to engage the support surface and roll in a forward direction. The pivot joint is mounted to the body to allow the wheel to pivot about a predetermined axis intersecting the support surface forward of the engagement between the wheel and the support surface. The wheel drives the body and pivots in response to frictional side slip forces between the wheel and the support surface without restraint from a steering linkage.

  • Patent number: 5586504
    Abstract: A propulsion and stabilization system with a plurality of superconducting magnetic devices affixed to the dual-keels of a vehicle, where the superconducting magnetic devices produce a magnetic field when energized. The system also includes a plurality of figure-eight shaped null-flux coils affixed to opposing vertical sides of slots in a guideway. The figure-eight shaped null-flux coils are vertically oriented, laterally cross-connected in parallel, longitudinally connected in series, and continue the length of the vertical slots providing levitation and guidance force. An external power source energizes the figure-eight shaped null-flux coils to create a magnetic traveling wave that interacts with the magnetic field produced by the superconducting magnets to impart motion to the vehicle.

  • Patent number: 5584248
    Abstract: A tamping vehicle uses a split tool mechanical vibrator having corresponding front and back vibrator units powered by a single motor. Sprockets and a synchronous sprocket belt drive front and back units to vibrate 180 degrees out of phase. A lubricant carrying belt carries oil to the top of a housing for lubricating and cooling various moving parts. Squeeze cylinders are used to move tamping tools to squeeze in positions by rotating the tamping tools about the same axes as rotation of vibration inducing shafts. Independently liftable gauge and field side tamping assemblies allow use at railroad switches and other locations where narrow width tamping is needed. A tamping tool provides easy connection to a tamping tool holder in such a way that two tamping tools may be mounted to one tool holder.

  • Patent number: 5575409
    Abstract: A nozzle configuration for a static mixer having a retaining shoulder with a square cross-section, an inclined front face and a flat retaining face that is normal to the longitudinal axis of the nozzle. An undercut having a octagonal cross-section is provided immediately adjacent to the retaining face. The faces of the undercut alternately define access surfaces, that are in the same plane as and join with corresponding outer edges of the retaining shoulder, and locking surfaces that undercut the corners of the retaining shoulder for retaining a locking hub on the nozzle. Travelling clockwise around the undercut, each locking face is inclined relative to the preceding access face at an angle of 40.degree. such that it is harder to unlock a locking hub in the clockwise direction than it is to lock it.

  • Patent number: 5575217
    Abstract: The wheel set comprises a pair of load-carrying wheels that run on a track, and that are steerable about parallel axes on a fixed portion, together with two pairs of guide wheels for bearing laterally against the track. The pairs of guide wheels are situated on either side of the load-carrying wheels, and they are carried by the same guide frame which is displaceable relative to the fixed portion only in rotation about a vertical axis. The guide frame is connected to the load-carrying wheels by a forced steering linkage for the load-carrying wheels. The fixed portion is constituted by a transverse box girder placed above the guide frame and provided with steering pivots for the load-carrying wheels, which pivots are placed beneath suspension cushions for the vehicle.

  • Patent number: 5573126
    Abstract: When slack-free railcar connector assemblies are placed under very high tensile loading, the connector assembly components will stretch and allow a typical "rigid" gravity wedge to descend into a fully seated position between the components and lock-in the tensile loads. The locked-in loads become additive in nature when successively encountered compressive loads are experienced by the connector assembly, thereby increasing the lateral drawbar angling forces, as well as accelerating coupling component wear. The wedge component of the present invention includes a means for vertically supporting and retaining the wedge in a holding position slightly above the normally fully seated position during the tensile loading, thereby eliminating the build up of tensile forces in the connector assembly.

  • Patent number: 5566623
    Abstract: An improved wheel and bearing assembly for a load transporting overhead trolley with a load support bracket having opposed stems mounting laterally offset wheels in rolling engagement with an overhead track has wheel-incorporated radially inner and outer race members with anti-friction load bearing balls between them in an annular trackway. The radially inner race member is split offset from the line connecting the center of the balls and formed of mating laterally outer and laterally inner abutting members which have laterally mating non-compressible radially abutting surfaces with radially aligned annular grooves therein. A circumferentially compressible retention spring is carried in one of the annular grooves and resiliently projects radially from the groove so that a snap fit is achieved when the inner race members are moved relatively laterally into mating assembly.

  • Patent number: 5562042
    Abstract: The elastic membrane is designed as a flat, three-dimensional object. It has prominences and depressions. This makes possible a deformation which is substantially free of stress, in particular free of tensile stress, simultaneously in all three dimensions. The elastic membranes of this type which are known today suffer from the disadvantage that they are not substantially free of stress, and in particular free of tensile stress, in all three dimensions and therefore cannot meet certain requirements.
