Abstract: An outlet gate assembly includes a body and an elongated discharge opening. An elongated discharge conduit is generally adjacent the discharge opening and is configured to pass material through either of the first discharge end and the second discharge end. A valve assembly controls the flow of material from the discharge opening into the discharge conduit and includes a direct motion component and a lost motion component and a lost motion coupling between the direct motion component and the lost motion component. Each of the direct motion component and the lost motion component is rotatable to move between an open position and a closed position and the valve assembly is operable from either the first end or the second end of the body.

Abstract: A gasket for a railroad car manway nozzle and cover includes an inner leg portion and an outer leg portion joined by a generally planar annular body portion defining an upper annular cover sealing surface and a lower annular nozzle body sealing surface. Concentric annular chevrons are formed on the upper and lower annular sealing surfaces. In one form, the chevrons have a uniform height relative to the upper and lower sealing surfaces. In a modified form, the height of the chevrons varies relative to the surfaces from the which they extend. The height of the chevrons is a minimum where the gasket is radially aligned with cover clamping bolts and a maximum at radial locations midway between clamping bolts. A tab depending from the outer leg portion provides visual verification of the presence of the gasket.

Abstract: A system for monitoring railroad cars comprising a hatch cover assembly including a cover body, a sensor, a wireless transmitter for transmitting data received from the sensor, a wireless receiver for receiving the data from the wireless transmitter, and a satellite transmitter for transmitting the data to a satellite. The wireless receiver and the satellite transmitter are attached to the hatch cover assembly. In one embodiment, the sensor is a pressure sensor having a sensing unit situated in the plenum of a vented hatch cover. In another embodiment, the sensor is an air flow sensor having a sensing unit situated in the plenum of a vented hatch cover. In another embodiment, the sensor is a chain tension sensor attached to a handbrake chain. In another embodiment, the sensor is a hatch cover position attached to the hatch cover assembly.

Abstract: A multiple port, parallel access, piping flange has a body with a forward face, a rear face and a throughbore. A plurality of extension segments include a partial bore extending from the forward face, and a radial bore in fluid communication with the partial bore, at least some of which are in communication with the throughbore. In one form, the piping flange includes a tube secured in the throughbore having holes in communication with the radial bores in some extension segments. A separate partial bore extends through the rear face of the body and communicates with at least one radial bore in at least one extension segment. A metal segmented ring is employed to support connection elements.

Abstract: A pickling process for descaling metal includes a two-stage filtering process to remove pickling liquor fog, mist, and/or vapors from a gas collected during the descaling process. The process includes a two-stage filtering arrangement that includes a first stage filter, which is arranged to remove a liquid phase of the pickling liquor from the gas, and a second stage filter, which is arranged to remove a gaseous phase of the pickling liquor the said gas. The recovered pickling liquor can advantageously be recycled for reuse because it is recovered in a relatively higher concentration that has heretofore been possible.
