Abstract: A process monitoring probe within a sample container is cleaned by flushing a sample process stream from the container and then discharging a jet of water from a nozzle at the probe within the container. A chemical cleaning agent is injected into the water to be discharged from the nozzle.

Abstract: A smooth, plastic-lined corrugated pipe having an intermediate layer of plastic foam. The pipe is made by internally coating a corrugated pipe with a foaming mixture and pressing an expandable cylinder of plastic sheet liner against the foaming mixture until the foam solidifies. An expandable mandrel apparatus presses the plastic sheet liner into position. The apparatus comprises a hollow cylinder, an elastomeric cylinder fitted on the outside of the hollow cylinder defining an annular space therebetween and a fluid conducting means communicating with the annular space.

Abstract: Support apparatus for a vertically disposed furnace having a unique mantle-to-bosh configuration and lower stack section to provide for expansion and contraction between the mantle and bosh jackets.

Abstract: A process for quenching hot coke in a one-spot coke quench car. The process utilizes a unique arrangement of pipes and spray nozzles to quench the hot coke in a substantially watertight coke quench car having a sloping bottom. A plurality of pipes are directed downwardly from a header mounted on the bench side of the quench car to provide solid streams of water onto the shallow coke bed portion at the top of the sloped bottom for a portion of the quench period. After an initial period a flow of water from a plurality of spray nozzles mounted on additional headers is directed onto the substantially horizontal deep coke bed portion for the remainder of the quenching period. The unvaporized quench liquid is retained in the watertight car until the completion of the quench cycle when it is rapidly drained away.

Abstract: Apparatus for an automatic system for cleaning a process monitoring probe inserted into a process stream for monitoring said stream. The apparatus comprises a flushing water supply, a high pressure water jet mixed with a cleansing agent and sequential timing apparatus for selectively applying the water jet to the process monitoring probe.

Abstract: A process for quenching hot coke discharged from an oven of a battery of coke ovens into a one-spot car. The process utilizes a unique arrangement of two sets of narrow angle spray nozzles to quench the coke. In addition to quenching the coke, one set of spray nozzles initially knocks down the peak portion of the coke pile and distributes the coke so that the exposed surface of the coke is substantially level. The quench liquid discharged through the narrow angle spray nozzles contacts about 50% to about 70% of the substantially level, exposed surface of the hot coke. Sufficient openings are provided adjacent the bottom of the one-spot car to drain the quench liquid to prevent the buildup of quench liquid in the quench car.

Abstract: Apparatus for providing the proper spread between the switch rail and stock rail in a railway switch which includes a heel block of unique design which assures accurate alignment of the parts of the switch heel block.

Abstract: Apparatus for use in positioning a pouring tube on a bottom pour nozzle of a hot metal casting vessel including a pouring tube support carriage having universal or two dimensional movement in a horizontal plane and pouring tube transfer car mounted on the carriage to extend the pouring tube from an inboard position adjacent the carriage to an outboard position in alignment with the bottom pour nozzle. The apparatus is designed to raise and lower the pouring tube with respect to the bottom pour nozzle when in alignment therewith. The apparatus is also provided to move the pouring tube from an inboard vertical position to a horizontal travel position and finally to a vertical outboard position with the bottom portion of the pouring tube projecting into the molten metal bath of a tundish positioned beneath the casting vessel and the top of the pouring tube engaging the casting vessel bottom pour nozzle. The pouring tube transfer car is designed to be rapidly withdrawn in an emergency.

Abstract: A process for controlling emissions resulting from hot coke being discharged from an oven of a battery of coke ovens from the beginning of discharge until the time when the coke arrives at a quenching station. The coke from the oven passes through a coke guide and a fume hood into an open-top, one-spot quenching car. The hood covers the car during discharge and is connected to an exhaust system, including a gas cleaning device, which draws air into the hood in an amount sufficient to control emissions and for combustion of the volatile matter and other combustibles emitted from the coke during the time coke is discharged into the quenching car and for a short period of time thereafter. During the movement of the open-top, one-spot quenching car from under the hood to the quenching station, the visible emissions given off by the hot coke are less than 40% opacity.

Abstract: Apparatus for use in guying transmission towers or the like which comprises an assembly of a plurality of lengths of wire strands which are anchored to a tension equalizer device at one end of the strand lengths and terminate in a single wire rope socket at the other ends thereof.

Abstract: A pipe is cradled at rest on a weighing scale at the end of a pipe mill production line. Pipe end sensors are driven axially in opposite directions until each one makes contact with an end of the pipe. Movement of each sensor toward an end of the pipe causes a pulse generator to produce pulses that decrement from a preset value indicative of the distance between two axially disposed reference points.

Abstract: The amount of solid carbon deposited on a surface by a gas during the coking cycle in a coke oven is determined by measuring the thickness by electrical resistance readings, as a function of time, of carbon deposited on a probe passing through the roof of the oven and into the path of the gases flowing out of the oven.

Abstract: Rectangular floor panels are supported at each corner by a pedestal head. The pedestal head is supported by a vertical post and is formed of a single piece of sheet metal. The head has four orthogonally disposed arms extending outwardly, and each arm is provided with depending surfaces that engage a face of the post.

Abstract: Method and apparatus for receiving and transporting hot coke in a coke oven pushing operation and controlling emissions resulting therefrom comprising a one spot quench car having a receptacle which is tiltable to a coke receiving position, a travel and quench position, and a coke discharging position. A hood structure is provided to confine the gases during pushing and a collecting main removes the gases to a remote location for cleaning thereof.
