Abstract: A method for controlling a device for metering granular material and a metering device for metering granular material comprises a feed for the granular material from a container into a metering chamber. A metering piston can be actuated by a control device such that a gap between the feed and the metering chamber is opened by a predefined first distance and a second distance which is greater than the first distance. At least one sensor is arranged in a delivery line leading away from the metering chamber and is connected to the control device so that the metering piston can be actuated for a predefined duration such that the gap between the feed for the granular material and the metering chamber can be opened by the second distance if a blockage of the granular material is detected by the at least one sensor, so that the blockage is dispersed.

Abstract: An independent cart system with safety functions prevents unintended motion independently within different sections of the track while permitting motion along other sections of the track. A safety controller receives one or more input signals corresponding to operating conditions along the track. A safety program executing in the safety controller monitors the state of the input signals to determine whether a safety function is to be executed. When a safety program is executed, the safety controller transmits an output signal to one or more segment controllers present in one section along the track. Each segment controller is responsible for regulating current flow to the coils mounted to the corresponding track segment. In response to the signal from the safety controller, each segment controller in the section controls the power output to the coils along that section of track to achieve the safe operation desired in that segment.

Abstract: There is a damper wedge for a railroad car truck. It has a removable and replaceable friction element that reciprocates on the wear plate of the side frame column of the railroad car truck. It has a non-metallic wear surface; a spring seat that, in use, engages a spring of the railroad car truck; and an inclined damper wedge surface having a primary angle, alpha, and a secondary angle, beta.

The nonmetallic wear surface material is mounted to a carrier that mounts removably to the damper wedge body. The carrier has fingers that span the wedge and that transfer shear and resist torsion, the fingers preventing the non-metallic member from migrating out of position.

Abstract: A self guarded frog copper weld fixture has a rail form and a pair of transverse locator arms. The rail form is configured to abut with a damaged rail frog and define a proper repaired geometry for the rail frog. A pair of locator arms transversely and vertically locate and secure the rail form against one of the rails of a damaged rail frog, by applying an opposing force against a second one of the damaged rail frog rails. Any wear will present as small gaps between the rail form and rail frog. The transverse locator arms are pivotal with respect to the rail form, and so may be rotated from transverse to the rail form to align longitudinally for compact transport or storage, and may also be reversed to allow either one of the longitudinal vertical side edges of the rail form to be abutted to the rail frog.

Abstract: A locked-axle spring compression system and method configured to raise a rail vehicle wheel off a rail and transport the raised wheel along a rail is presented. In one embodiment, the present disclosure discloses a system that can raise the locked-axle rail wheel off the rail and allowing the locked-axle train to be transported off the main line. One or more coil springs can be disposed between the truck frame and the journal box to distribute the weight of the train and forces acting thereon. The present disclosure provides a technological solution missing from conventional systems by at least providing a platform for an actuator configured to exert a force on one or more train elements to compress the coil springs and allow the locked-axle wheel to be raised off a surface (e.g., railroad track rail), by overcoming the coil spring pressure to raise the wheel off the rail.
